Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/mdp5: Fix global state lock backoff
We need to grab the lock after the early return for !hwpipe case.
Otherwise, we could have hit contention yet still returned 0.
Fixes an issue that the new CONFIG_DRM_DEBUG_MODESET_LOCK stuff flagged
in CI:

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFS: Fix a race when updating an existing write
After nfs_lock_and_join_requests() tests for whether the request is
still attached to the mapping, nothing prevents a call to
nfs_inode_remove_request() from succeeding until we actually lock the
page group.
The reason is that whoever called nfs_inode_remove_request() doesn't
necessarily have a lock on the page group head.
So in order to avoid races, let's take the page group lock earlier in
nfs_lock_and_join_requests(), and hold it across the removal of the
request in nfs_inode_remove_request().

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: microchip: Fix refcount leak in mc_pcie_init_irq_domains()
of_get_next_child() returns a node pointer with refcount incremented, so we
should use of_node_put() on it when we don't need it anymore.
mc_pcie_init_irq_domains() only calls of_node_put() in the normal path,
missing it in some error paths. Add missing of_node_put() to avoid
refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Drop snd_BUG_ON() from snd_usbmidi_output_open()
snd_usbmidi_output_open() has a check of the NULL port with
snd_BUG_ON(). snd_BUG_ON() was used as this shouldn't have happened,
but in reality, the NULL port may be seen when the device gives an
invalid endpoint setup at the descriptor, hence the driver skips the
allocation. That is, the check itself is valid and snd_BUG_ON()
should be dropped from there. Otherwise it's confusing as if it were
a real bug, as recently syzbot stumbled on it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: fix memory leak in mlx5e_fs_tt_redirect_any_create
The memory pointed to by the fs->any pointer is not freed in the error
path of mlx5e_fs_tt_redirect_any_create, which can lead to a memory leak.
Fix by freeing the memory in the error path, thereby making the error path
identical to mlx5e_fs_tt_redirect_any_destroy().

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/handshake: fix null-ptr-deref in handshake_nl_done_doit()
We should not call trace_handshake_cmd_done_err() if socket lookup has failed.
Also we should call trace_handshake_cmd_done_err() before releasing the file,
otherwise dereferencing sock->sk can return garbage.

Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: tegra20-slink: fix UAF in tegra_slink_remove()
After calling spi_unregister_master(), the refcount of master will
be decrease to 0, and it will be freed in spi_controller_release(),
the device data also will be freed, so it will lead a UAF when using
'tspi'. To fix this, get the master before unregister and put it when
finish using it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cpufreq: amd-pstate: fix global sysfs attribute type
In commit 3666062b87ec ("cpufreq: amd-pstate: move to use bus_get_dev_root()")
the "amd_pstate" attributes where moved from a dedicated kobject to the
cpu root kobject.
While the dedicated kobject expects to contain kobj_attributes the root
kobject needs device_attributes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: do not allow CHAIN_ID to refer to another table
When doing lookups for chains on the same batch by using its ID, a chain
from a different table can be used. If a rule is added to a table but
refers to a chain in a different table, it will be linked to the chain in
table2, but would have expressions referring to objects in table1.
Then, when table1 is removed, the rule will not be removed as its linked to
a chain in table2. When expressions in the rule are processed or removed,
that will lead to a use-after-free.
When looking for chains by ID, use the table that was used for the lookup
by name, and only return chains belonging to that same table.

Summary
In the Linux kernel, the following vulnerability has been resolved:
misc: fastrpc: fix possible map leak in fastrpc_put_args
copy_to_user() failure would cause an early return without cleaning up
the fdlist, which has been updated by the DSP. This could lead to map
leak. Fix this by redirecting to a cleanup path on failure, ensuring
that all mapped buffers are properly released before returning.

Summary
In the Linux kernel, the following vulnerability has been resolved:
comedi: fix race between polling and detaching
syzbot reports a use-after-free in comedi in the below link, which is
due to comedi gladly removing the allocated async area even though poll
requests are still active on the wait_queue_head inside of it. This can
cause a use-after-free when the poll entries are later triggered or
removed, as the memory for the wait_queue_head has been freed. We need
to check there are no tasks queued on any of the subdevices' wait queues
before allowing the device to be detached by the `COMEDI_DEVCONFIG`
ioctl.
Tasks will read-lock `dev->attach_lock` before adding themselves to the
subdevice wait queue, so fix the problem in the `COMEDI_DEVCONFIG` ioctl
handler by write-locking `dev->attach_lock` before checking that all of
the subdevices are safe to be deleted. This includes testing for any
sleepers on the subdevices' wait queues. It remains locked until the
device has been detached. This requires the `comedi_device_detach()`
function to be refactored slightly, moving the bulk of it into new
function `comedi_device_detach_locked()`.
Note that the refactor of `comedi_device_detach()` results in
`comedi_device_cancel_all()` now being called while `dev->attach_lock`
is write-locked, which wasn't the case previously, but that does not
matter.
Thanks to Jens Axboe for diagnosing the problem and co-developing this
patch.

This can\ncause a use-after-free when the poll entries are later triggered or\nremoved, as the memory for the wait_queue_head has been freed.

This includes testing for any\nsleepers on the subdevices\u0027 wait queues. It remains locked until the\ndevice has been detached. This requires the `comedi_device_detach()`\nfunction to be refactored slightly, moving the bulk of it into new\nfunction `comedi_device_detach_locked()`.\n\nNote that the refactor of `comedi_device_detach()` results in\n`comedi_device_cancel_all()` now being called while `dev-\u003eattach_lock`\nis write-locked, which wasn\u0027t the case previously, but that does not\nmatter.\n\nThanks to Jens Axboe for diagnosing the problem and co-developing this\npatch."

Summary
In the Linux kernel, the following vulnerability has been resolved:
cpufreq: amd-pstate-ut: Fix kernel panic when loading the driver
After loading the amd-pstate-ut driver, amd_pstate_ut_check_perf()
and amd_pstate_ut_check_freq() use cpufreq_cpu_get() to get the policy
of the CPU and mark it as busy.
In these functions, cpufreq_cpu_put() should be used to release the
policy, but it is not, so any other entity trying to access the policy
is blocked indefinitely.
One such scenario is when amd_pstate mode is changed, leading to the
following splat:
[ 1332.103727] INFO: task bash:2929 blocked for more than 120 seconds.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: usb: asix_devices: add phy_mask for ax88772 mdio bus
Without setting phy_mask for ax88772 mdio bus, current driver may create
at most 32 mdio phy devices with phy address range from 0x00 ~ 0x1f.
DLink DUB-E100 H/W Ver B1 is such a device. However, only one main phy
device will bind to net phy driver. This is creating issue during system
suspend/resume since phy_polling_mode() in phy_state_machine() will
directly deference member of phydev->drv for non-main phy devices. Then
NULL pointer dereference issue will occur. Due to only external phy or
internal phy is necessary, add phy_mask for ax88772 mdio bus to workarnoud
the issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix memleak due to fentry attach failure
If it fails to attach fentry, the allocated bpf trampoline image will be
left in the system. That can be verified by checking /proc/kallsyms.
This meamleak can be verified by a simple bpf program as follows:
SEC("fentry/trap_init")
int fentry_run()
{
return 0;
}
It will fail to attach trap_init because this function is freed after
kernel init, and then we can find the trampoline image is left in the
system by checking /proc/kallsyms.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: Fix potential invalid access when MAC list is empty
list_first_entry() never returns NULL - if the list is empty, it still
returns a pointer to an invalid object, leading to potential invalid
memory access when dereferenced.
Fix this by using list_first_entry_or_null instead of list_first_entry.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix memory leaks in __check_func_call
kmemleak reports this issue:
unreferenced object 0xffff88817139d000 (size 2048):
comm "test_progs", pid 33246, jiffies 4307381979 (age 45851.820s)
hex dump (first 32 bytes):

[<0000000000506b7f>] entry_SYSCALL_64_after_hwframe+0x63/0xcd
The root case here is: In function prepare_func_exit(), the callee is
not released in the abnormal scenario after "state->curframe--;". To
fix, move "state->curframe--;" to the very bottom of the function,
right when we free callee and reset frame[] pointer to NULL, as Andrii
suggested.
In addition, function __check_func_call() has a similar problem. In
the abnormal scenario before "state->curframe++;", the callee also
should be released by free_func_state().

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: storvsc: Fix handling of virtual Fibre Channel timeouts
Hyper-V provides the ability to connect Fibre Channel LUNs to the host
system and present them in a guest VM as a SCSI device. I/O to the vFC
device is handled by the storvsc driver. The storvsc driver includes a
partial integration with the FC transport implemented in the generic
portion of the Linux SCSI subsystem so that FC attributes can be displayed
in /sys. However, the partial integration means that some aspects of vFC
don't work properly. Unfortunately, a full and correct integration isn't
practical because of limitations in what Hyper-V provides to the guest.
In particular, in the context of Hyper-V storvsc, the FC transport timeout
function fc_eh_timed_out() causes a kernel panic because it can't find the
rport and dereferences a NULL pointer. The original patch that added the
call from storvsc_eh_timed_out() to fc_eh_timed_out() is faulty in this
regard.
In many cases a timeout is due to a transient condition, so the situation
can be improved by just continuing to wait like with other I/O requests
issued by storvsc, and avoiding the guaranteed panic. For a permanent
failure, continuing to wait may result in a hung thread instead of a panic,
which again may be better.
So fix the panic by removing the storvsc call to fc_eh_timed_out(). This
allows storvsc to keep waiting for a response. The change has been tested
by users who experienced a panic in fc_eh_timed_out() due to transient
timeouts, and it solves their problem.
In the future we may want to deprecate the vFC functionality in storvsc
since it can't be fully fixed. But it has current users for whom it is
working well enough, so it should probably stay for a while longer.

I/O to the vFC\ndevice is handled by the storvsc driver. The storvsc driver includes a\npartial integration with the FC transport implemented in the generic\nportion of the Linux SCSI subsystem so that FC attributes can be displayed\nin /sys. However, the partial integration means that some aspects of vFC\ndon\u0027t work properly. Unfortunately, a full and correct integration isn\u0027t\npractical because of limitations in what Hyper-V provides to the guest.\n\nIn particular, in the context of Hyper-V storvsc, the FC transport timeout\nfunction fc_eh_timed_out() causes a kernel panic because it can\u0027t find the\nrport and dereferences a NULL pointer. The original patch that added the\ncall from storvsc_eh_timed_out() to fc_eh_timed_out() is faulty in this\nregard.\n\nIn many cases a timeout is due to a transient condition, so the situation\ncan be improved by just continuing to wait like with other I/O requests\nissued by storvsc, and avoiding the guaranteed panic. For a permanent\nfailure, continuing to wait may result in a hung thread instead of a panic,\nwhich again may be better.\n\nSo fix the panic by removing the storvsc call to fc_eh_timed_out(). This\nallows storvsc to keep waiting for a response. The change has been tested\nby users who experienced a panic in fc_eh_timed_out() due to transient\ntimeouts, and it solves their problem.\n\nIn the future we may want to deprecate the vFC functionality in storvsc\nsince it can\u0027t be fully fixed. But it has current users for whom it is\nworking well enough, so it should probably stay for a while longer."

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: cp2112: prevent a buffer overflow in cp2112_xfer()
Smatch warnings:
drivers/hid/hid-cp2112.c:793 cp2112_xfer() error: __memcpy()
'data->block[1]' too small (33 vs 255)
drivers/hid/hid-cp2112.c:793 cp2112_xfer() error: __memcpy() 'buf' too
small (64 vs 255)
The 'read_length' variable is provided by 'data->block[0]' which comes
from user and it(read_length) can take a value between 0-255. Add an
upper bound to 'read_length' variable to prevent a buffer overflow in
memcpy().

CP2112 deployments typically have responding I2C slaves (EEPROMs/sensors) that the attacker can address.\nPR:L - i2cdev_open() performs no capability check; access is governed by /dev/i2c-* permissions, commonly 0660 root:i2c or similarly granted to unprivileged service accounts on embedded/industrial systems. That is basic local access, not real root/init-namespace admin rights.\nUI:N - Exploitation requires only the attacker issuing ioctl(I2C_SMBUS) with I2C_SMBUS_I2C_BLOCK_DATA; no victim action is needed.\nS:U - This is ordinary kernel memory corruption within the host OS authority (local privilege escalation/DoS), with no VM escape, IOMMU bypass, or other cross-boundary impact.\nC:H - The bug is an out-of-bounds write of attacker-chosen length (and I2C-sourced contents) past union i2c_smbus_data on the stack, which is memory corruption that can be leveraged for information disclosure.\nI:H - Out-of-bounds stack write via memcpy(data-\u003eblock+1, buf, read_length) with read_length up to 61 into a 33-byte destination enables integrity compromise and potential control-flow hijacking.\nA:H - The same memory corruption can crash the kernel (oops/panic) even when not fully exploited for code execution."

The attacker needs local control of an assigned VF \u2014 kernel/root inside a guest VM, or possession of the VFIO device \u2014 so reachability is local, not network or adjacent.\nAC:L - The attacker simply loops `VIRTCHNL_OP_ADD_CLOUD_FILTER` with a filter matching its own MAC; there is no duplicate check, no race, and no memory grooming, so growth is deterministic from the first message. The only precondition \u2014 ADq enabled with spoofchk off \u2014 is inherent to any ADq-capable SR-IOV deployment and is a standard runtime configuration.\nPR:L - Only the ability to drive the VF\u0027s admin queue is needed, which is a low-privileged position relative to the host PF driver under attack, and no host privileges of any kind are required. Notably `i40e_validate_cloud_filter()` accepts basic-mode filters from an untrusted VF, so even the trusted-VF bit is unnecessary.\nUI:N - The malicious VF drives the entire message flood on its own initiative. No host administrator or other user action is required at exploitation time.\nS:C - The attacking VF resides in a guest VM (or VF-assigned container) while the unbounded allocations, leaked memory, service-task starvation and hardware filter-table exhaustion all land in the host PF driver\u0027s security authority. The damage extends to the host and to every other VF sharing the adapter, crossing the guest/host and inter-tenant SR-IOV boundary.\nC:N - The defect is a missing upper bound on counted allocations; there is no out-of-bounds read, no uninitialized data returned, and the VF only ever receives an `aq_ret` status code. The `u16` counter wrap has no consumers, so no memory contents are exposed.\nI:L - Each successful add emits an unratelimited `dev_info()` from `i40e_add_del_cloud_filter()`, so a guest can push tens of thousands of lines through the host kernel log and roll away the host\u0027s diagnostic and audit records, and can also monopolize the PF-wide hardware cloud-filter table so the host\u0027s and other tenants\u0027 legitimate steering rules fail to install. The attacker has no control over which host data is displaced, so the modification is limited rather than arbitrary.\nA:H - A guest can allocate `struct i40e_cloud_filter` objects without limit until the host OOMs, and because `i40e_free_vf_res()`/`i40e_free_vfs()` never walk `vf-\u003ecloud_filter_list`, the memory is permanently leaked across every VF reset and SR-IOV teardown. The flood also monopolizes the PF\u0027s single service-task workqueue with synchronous firmware AQ round-trips, stalling watchdog, link and reset handling and taking host networking \u2014 and thus every guest on the adapter \u2014 down with it."

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs: Prevent file descriptor table allocations exceeding INT_MAX
When sysctl_nr_open is set to a very high value (for example, 1073741816
as set by systemd), processes attempting to use file descriptors near
the limit can trigger massive memory allocation attempts that exceed
INT_MAX, resulting in a WARNING in mm/slub.c:
WARNING: CPU: 0 PID: 44 at mm/slub.c:5027 __kvmalloc_node_noprof+0x21a/0x288
This happens because kvmalloc_array() and kvmalloc() check if the
requested size exceeds INT_MAX and emit a warning when the allocation is
not flagged with __GFP_NOWARN.
Specifically, when nr_open is set to 1073741816 (0x3ffffff8) and a
process calls dup2(oldfd, 1073741880), the kernel attempts to allocate:
- File descriptor array: 1073741880 * 8 bytes = 8,589,935,040 bytes
- Multiple bitmaps: ~400MB
- Total allocation size: > 8GB (exceeding INT_MAX = 2,147,483,647)
Reproducer:
1. Set /proc/sys/fs/nr_open to 1073741816:
# echo 1073741816 > /proc/sys/fs/nr_open
2. Run a program that uses a high file descriptor:
#include <unistd.h>
#include <sys/resource.h>
int main() {
struct rlimit rlim = {1073741824, 1073741824};
setrlimit(RLIMIT_NOFILE, &rlim);
dup2(2, 1073741880); // Triggers the warning
return 0;
}
3. Observe WARNING in dmesg at mm/slub.c:5027
systemd commit a8b627a introduced automatic bumping of fs.nr_open to the
maximum possible value. The rationale was that systems with memory
control groups (memcg) no longer need separate file descriptor limits
since memory is properly accounted. However, this change overlooked
that:
1. The kernel's allocation functions still enforce INT_MAX as a maximum
size regardless of memcg accounting
2. Programs and tests that legitimately test file descriptor limits can
inadvertently trigger massive allocations
3. The resulting allocations (>8GB) are impractical and will always fail
systemd's algorithm starts with INT_MAX and keeps halving the value
until the kernel accepts it. On most systems, this results in nr_open
being set to 1073741816 (0x3ffffff8), which is just under 1GB of file
descriptors.
While processes rarely use file descriptors near this limit in normal
operation, certain selftests (like
tools/testing/selftests/core/unshare_test.c) and programs that test file
descriptor limits can trigger this issue.
Fix this by adding a check in alloc_fdtable() to ensure the requested
allocation size does not exceed INT_MAX. This causes the operation to
fail with -EMFILE instead of triggering a kernel warning and avoids the
impractical >8GB memory allocation request.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: unset reloc control if transaction commit fails in prepare_to_relocate()
In btrfs_relocate_block_group(), the rc is allocated. Then
btrfs_relocate_block_group() calls
relocate_block_group()
prepare_to_relocate()
set_reloc_control()
that assigns rc to the variable fs_info->reloc_ctl. When
prepare_to_relocate() returns, it calls
btrfs_commit_transaction()
btrfs_start_dirty_block_groups()
btrfs_alloc_path()
kmem_cache_zalloc()
which may fail for example (or other errors could happen). When the
failure occurs, btrfs_relocate_block_group() detects the error and frees
rc and doesn't set fs_info->reloc_ctl to NULL. After that, in
btrfs_init_reloc_root(), rc is retrieved from fs_info->reloc_ctl and
then used, which may cause a use-after-free bug.
This possible bug can be triggered by calling btrfs_ioctl_balance()
before calling btrfs_ioctl_defrag().
To fix this possible bug, in prepare_to_relocate(), check if
btrfs_commit_transaction() fails. If the failure occurs,
unset_reloc_control() is called to set fs_info->reloc_ctl to NULL.
The error log in our fault-injection testing is shown as follows:

If the failure occurs,\nunset_reloc_control() is called to set fs_info-\u003ereloc_ctl to NULL.\n\nThe error log in our fault-injection testing is shown as follows:\n\n [ 58.751070] BUG: KASAN: use-after-free in btrfs_init_reloc_root+0x7ca/0x920 [btrfs]\n ...\n [ 58.753577] Call Trace:\n ...\n [ 58.755800] kasan_report+0x45/0x60\n [ 58.756066] btrfs_init_reloc_root+0x7ca/0x920 [btrfs]\n [ 58.757304] record_root_in_trans+0x792/0xa10 [btrfs]\n [ 58.757748] btrfs_record_root_in_trans+0x463/0x4f0 [btrfs]\n [ 58.758231] start_transaction+0x896/0x2950 [btrfs]\n [ 58.758661] btrfs_defrag_root+0x250/0xc00 [btrfs]\n [ 58.759083] btrfs_ioctl_defrag+0x467/0xa00 [btrfs]\n [ 58.759513] btrfs_ioctl+0x3c95/0x114e0 [btrfs]\n ...\n [ 58.768510] Allocated by task 23683:\n [ 58.768777] ____kasan_kmalloc+0xb5/0xf0\n [ 58.769069] __kmalloc+0x227/0x3d0\n [ 58.769325] alloc_reloc_control+0x10a/0x3d0 [btrfs]\n [ 58.769755] btrfs_relocate_block_group+0x7aa/0x1e20 [btrfs]\n [ 58.770228] btrfs_relocate_chunk+0xf1/0x760 [btrfs]\n [ 58.770655] __btrfs_balance+0x1326/0x1f10 [btrfs]\n [ 58.771071] btrfs_balance+0x3150/0x3d30 [btrfs]\n [ 58.771472] btrfs_ioctl_balance+0xd84/0x1410 [btrfs]\n [ 58.771902] btrfs_ioctl+0x4caa/0x114e0 [btrfs]\n ...\n [ 58.773337] Freed by task 23683:\n ...\n [ 58.774815] kfree+0xda/0x2b0\n [ 58.775038] free_reloc_control+0x1d6/0x220 [btrfs]\n [ 58.775465] btrfs_relocate_block_group+0x115c/0x1e20 [btrfs]\n [ 58.775944] btrfs_relocate_chunk+0xf1/0x760 [btrfs]\n [ 58.776369] __btrfs_balance+0x1326/0x1f10 [btrfs]\n [ 58.776784] btrfs_balance+0x3150/0x3d30 [btrfs]\n [ 58.777185] btrfs_ioctl_balance+0xd84/0x1410 [btrfs]\n [ 58.777621] btrfs_ioctl+0x4caa/0x114e0 [btrfs]\n ..."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: core: Remove the /proc/scsi/${proc_name} directory earlier
Remove the /proc/scsi/${proc_name} directory earlier to fix a race
condition between unloading and reloading kernel modules. This fixes a bug
introduced in 2009 by commit 77c019768f06 ("[SCSI] fix /proc memory leak in
the SCSI core").
Fix the following kernel warning:

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: usb: asix_devices: Fix PHY address mask in MDIO bus initialization
Syzbot reported shift-out-of-bounds exception on MDIO bus initialization.
The PHY address should be masked to 5 bits (0-31). Without this
mask, invalid PHY addresses could be used, potentially causing issues
with MDIO bus operations.
Fix this by masking the PHY address with 0x1f (31 decimal) to ensure
it stays within the valid range.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_event: call disconnect callback before deleting conn
In hci_cs_disconnect, we do hci_conn_del even if disconnection failed.
ISO, L2CAP and SCO connections refer to the hci_conn without
hci_conn_get, so disconn_cfm must be called so they can clean up their
conn, otherwise use-after-free occurs.

"value": "AV:A - The bug is in the Bluetooth HCI event handler, triggered by a Command Status event for HCI_Disconnect whose failure status is induced by a peer device terminating the link concurrently with the host\u0027s disconnect. Exploitation requires only Bluetooth radio proximity to the target (phones, cars, headsets, laptops), which is CVSS Adjacent.\nAC:L - The attacker controls both sides of the race: closing the last L2CAP channel forces hcon-\u003edisc_timeout=0 and an immediate host Disconnect, and the attacker then tears down the link-layer connection at that moment so the controller answers Unknown Connection Identifier/Command Disallowed. The attempt costs nothing and can be repeated indefinitely by reconnecting.\nPR:N - No credentials or pairing are required \u2014 an L2CAP/ISO connection reaches l2cap_conn_add/iso_conn_add before authentication, and no capability check exists on the path. The attacker needs no account or privilege on the target system.\nUI:N - The dangling l2cap_conn-\u003ehchan and iso_conn-\u003ehcon are used by ordinary background traffic \u2014 the reported crash occurred in bluetoothd\u0027s normal write path \u2014 with no victim action needed. The attacker can also trigger the use itself via further protocol activity.\nS:U - The freed objects and the resulting corruption are entirely within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed hci_chan lives in the generic kmalloc-64 cache and hci_send_acl dereferences chan-\u003econn-\u003ehdev straight out of it, so a groomed reallocation yields a controlled pointer read of arbitrary kernel memory. Per kernel guidance, use-after-free is scored High confidentiality.\nI:H - Beyond the read primitive, hci_queue_acl writes skb list pointers into the freed object\u0027s data_q and later code operates on the forged hci_conn, giving heap-spray-driven write and control-flow influence. Use-after-free of a sprayable kmalloc object is scored High integrity.\nA:H - The bug reproduces as a KASAN slab-use-after-free in hci_send_acl and as a NULL pointer dereference oops in iso_sock_sendmsg, both fatal to the kernel context. Any kernel oops/panic is High availability."

Code: a83f15e0 0200001a 0630a0e1 c3ffffea (f201f0e7)
The issue seems similar to commit 90b3b339364c ("net: hisilicon: Fix a BUG
trigered by wrong bytes_compl") and potentially introduced by commit
b38c83dd0866 ("bgmac: simplify tx ring index handling").
If there is an RX interrupt between setting ring->end
and netdev_sent_queue() we can hit the BUG_ON as bgmac_dma_tx_free()
can miscalculate the queue size while called from bgmac_poll().
The machine which triggered the BUG runs a v4.14 RT kernel - but the issue
seems present in mainline too.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xsk: fix refcount underflow in error path
Fix a refcount underflow problem reported by syzbot that can happen
when a system is running out of memory. If xp_alloc_tx_descs() fails,
and it can only fail due to not having enough memory, then the error
path is triggered. In this error path, the refcount of the pool is
decremented as it has incremented before. However, the reference to
the pool in the socket was not nulled. This means that when the socket
is closed later, the socket teardown logic will think that there is a
pool attached to the socket and try to decrease the refcount again,
leading to a refcount underflow.
I chose this fix as it involved adding just a single line. Another
option would have been to move xp_get_pool() and the assignment of
xs->pool to after the if-statement and using xs_umem->pool instead of
xs->pool in the whole if-statement resulting in somewhat simpler code,
but this would have led to much more churn in the code base perhaps
making it harder to backport.

Summary
In the Linux kernel, the following vulnerability has been resolved:
posix-timers: Ensure timer ID search-loop limit is valid
posix_timer_add() tries to allocate a posix timer ID by starting from the
cached ID which was stored by the last successful allocation.
This is done in a loop searching the ID space for a free slot one by
one. The loop has to terminate when the search wrapped around to the
starting point.
But that's racy vs. establishing the starting point. That is read out
lockless, which leads to the following problem:
CPU0 CPU1
posix_timer_add()
start = sig->posix_timer_id;
lock(hash_lock);
... posix_timer_add()
if (++sig->posix_timer_id < 0)
start = sig->posix_timer_id;
sig->posix_timer_id = 0;
So CPU1 can observe a negative start value, i.e. -1, and the loop break
never happens because the condition can never be true:
if (sig->posix_timer_id == start)
break;
While this is unlikely to ever turn into an endless loop as the ID space is
huge (INT_MAX), the racy read of the start value caught the attention of
KCSAN and Dmitry unearthed that incorrectness.
Rewrite it so that all id operations are under the hash lock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: sme: cap SSID length in __cfg80211_connect_result()
If the ssid->datalen is more than IEEE80211_MAX_SSID_LEN (32) it would
lead to memory corruption so add some bounds checking.

This is the standard WiFi frame-injection adjacent-network vector.\nAC:L - The attacker fully controls every precondition \u2014 the rogue AP\u0027s per-link beacon contents, the SSID element length (up to 255), the link IDs, and which link is used for association \u2014 and can force (re)association with deauthentication frames. No condition lies outside the attacker\u0027s control.\nPR:N - No credentials or account on the victim system are required; the code runs during association processing on the client, triggered purely by frames the attacker transmits. An open/evil-twin AP suffices.\nUI:N - Association and roaming are performed automatically by the WiFi stack for remembered and open networks, and an attacker can force reassociation with deauth frames, so no deliberate victim action is needed.\nS:U - The corruption is confined to kernel heap memory belonging to the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `wdev-\u003eu.client.ssid_len` is set to the full unclamped datalen, so `nl80211.c:4530` copies up to 223 bytes of adjacent kernel heap out to userspace via NL80211_ATTR_SSID, and the write primitive over BSS pointers enables broader disclosure.\nI:H - An out-of-bounds write of up to 223 fully attacker-controlled bytes overwrites `wdev-\u003elinks[]`, including `client.current_bss` pointers that are later dereferenced and refcount-decremented, yielding a controlled-pointer primitive suitable for control-flow hijacking.\nA:H - Corrupting the `wdev-\u003elinks[]` BSS pointers and surrounding `ieee80211_sub_if_data` state leads to bogus pointer dereferences in `cfg80211_wdev_release_bsses()` and kernel panic; heap overflow reliably crashes the system."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: tunnels: annotate lockless accesses to dev->needed_headroom
IP tunnels can apparently update dev->needed_headroom
in their xmit path.
This patch takes care of three tunnels xmit, and also the
core LL_RESERVED_SPACE() and LL_RESERVED_SPACE_EXTRA()
helpers.
More changes might be needed for completeness.
BUG: KCSAN: data-race in ip_tunnel_xmit / ip_tunnel_xmit

On hibernating, pm core calls into related hooks in sequence like:
.freeze
.freeze_noirq
.thaw_noirq
.thaw
With .thaw_noirq hook being absent, the clock will be disabled in a
unbalanced call which results the warning above.
imx_uart_freeze()
clk_prepare_enable()
imx_uart_suspend_noirq()
clk_disable()
imx_uart_thaw
clk_disable_unprepare()
Adding the missing .thaw_noirq hook as imx_uart_resume_noirq() will have
the call sequence corrected as below and thus fix the warning.
imx_uart_freeze()
clk_prepare_enable()
imx_uart_suspend_noirq()
clk_disable()
imx_uart_resume_noirq()
clk_enable()
imx_uart_thaw
clk_disable_unprepare()

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/ism: fix concurrency management in ism_cmd()
The s390x ISM device data sheet clearly states that only one
request-response sequence is allowable per ISM function at any point in
time. Unfortunately as of today the s390/ism driver in Linux does not
honor that requirement. This patch aims to rectify that.
This problem was discovered based on Aliaksei's bug report which states
that for certain workloads the ISM functions end up entering error state
(with PEC 2 as seen from the logs) after a while and as a consequence
connections handled by the respective function break, and for future
connection requests the ISM device is not considered -- given it is in a
dysfunctional state. During further debugging PEC 3A was observed as
well.
A kernel message like
[ 1211.244319] zpci: 061a:00:00.0: Event 0x2 reports an error for PCI function 0x61a
is a reliable indicator of the stated function entering error state
with PEC 2. Let me also point out that a kernel message like
[ 1211.244325] zpci: 061a:00:00.0: The ism driver bound to the device does not support error recovery
is a reliable indicator that the ISM function won't be auto-recovered
because the ISM driver currently lacks support for it.
On a technical level, without this synchronization, commands (inputs to
the FW) may be partially or fully overwritten (corrupted) by another CPU
trying to issue commands on the same function. There is hard evidence that
this can lead to DMB token values being used as DMB IOVAs, leading to
PEC 2 PCI events indicating invalid DMA. But this is only one of the
failure modes imaginable. In theory even completely losing one command
and executing another one twice and then trying to interpret the outputs
as if the command we intended to execute was actually executed and not
the other one is also possible. Frankly, I don't feel confident about
providing an exhaustive list of possible consequences.

The attacker never needs local access.\nAC:L - The attacker controls both sides of the race by churning concurrent SMC-D connection setups and teardowns, which execute `ism_cmd()` in parallel on different CPUs (setup under `smc_*_lgr_pending`, teardown under no serialization at all). The commit confirms ordinary workloads already hit this \"after a while,\" so deliberate hammering is reliable.\nPR:N - The SMC CLC handshake has no authentication and `af_smc.c` contains no capability checks, so `smc_ism_cantalk()` reaches `ism_cmd()` with peer-supplied GID/CHID before any credential is ever presented. Locally the equivalent path needs only an unprivileged AF_SMC socket or `TCP_ULP=smc`.\nUI:N - Triggering requires only that the attacker open and close connections; no action by any local user or administrator is needed. The victim host merely has to have an ISM device and SMC-D in use, which is configuration, not interaction.\nS:U - The corrupted commands and misrouted DMB registrations affect resources managed by the same kernel/ISM-function security authority, and bad DMA is contained by the zPCI translation hardware. No hypervisor, LPAR, or IOMMU boundary is escaped.\nC:H - A response read back for the wrong command makes `ism_register_dmb()` store another command\u0027s `dmb_tok`, and that token is advertised to the remote peer in the CLC message, so the local socket ends up reading a different connection\u0027s DMB contents \u2014 cross-connection, cross-user, cross-LPAR payload disclosure. Corrupted `REG_DMB.rgid` similarly exposes a buffer to an unintended remote GID.\nI:H - With a misassigned DMB token the remote peer\u0027s ISM move writes application data directly into a different connection\u0027s receive buffer, and a corrupted `UNREG_DMB.dmb_tok` unregisters the wrong DMB in firmware while the driver\u0027s view diverges. The maintainer states commands may be partially overwritten or executed twice with outputs misinterpreted, and declines to bound the consequences.\nA:H - Command corruption puts the ISM PCI function into error state (PEC 2/3A), breaking every SMC-D connection on it, and the ISM driver implements no error recovery so the device is permanently excluded from future connections until manual intervention. This is a persistent denial of service affecting all users of the adapter."

Summary
In the Linux kernel, the following vulnerability has been resolved:
misc: fastrpc: fix memory corruption on probe
Add the missing sanity check on the probed-session count to avoid
corrupting memory beyond the fixed-size slab-allocated session array
when there are more than FASTRPC_MAX_SESSIONS sessions defined in the
devicetree.

Summary
In the Linux kernel, the following vulnerability has been resolved:
start_kernel: Add __no_stack_protector function attribute
Back during the discussion of
commit a9a3ed1eff36 ("x86: Fix early boot crash on gcc-10, third try")
we discussed the need for a function attribute to control the omission
of stack protectors on a per-function basis; at the time Clang had
support for no_stack_protector but GCC did not. This was fixed in
gcc-11. Now that the function attribute is available, let's start using
it.
Callers of boot_init_stack_canary need to use this function attribute
unless they're compiled with -fno-stack-protector, otherwise the canary
stored in the stack slot of the caller will differ upon the call to
boot_init_stack_canary. This will lead to a call to __stack_chk_fail()
then panic.

Per the pure-crash guidance, there is no information disclosure.\nI:N - Nothing is written out of bounds and no object is corrupted \u2014 the canary in the caller\u0027s frame is intact; the comparison is a false positive caused by the canary *source* changing underneath it. There is no write primitive and no control-flow hijack potential.\nA:H - The outcome is `panic(\"stack-protector: Kernel stack is corrupted in: start_kernel\")`, i.e. an unbootable system, or a panic during secondary-CPU bring-up via `start_secondary()` on hotplug/resume. This is total, unrecoverable loss of availability for the affected machine."

Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: uinput - zero-initialize uinput_ff_upload_compat to avoid info leak
Struct ff_effect_compat is embedded twice inside
uinput_ff_upload_compat, contains internal padding. In particular, there
is a hole after struct ff_replay to satisfy alignment requirements for
the following union member. Without clearing the structure,
copy_to_user() may leak stack data to userspace.
Initialize ff_up_compat to zero before filling valid fields.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm: bridge: anx7625: Fix NULL pointer dereference with early IRQ
If the interrupt occurs before resource initialization is complete, the
interrupt handler/worker may access uninitialized data such as the I2C
tcpc_client device, potentially leading to NULL pointer dereference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: tcpm: fix warning when handle discover_identity message
Since both source and sink device can send discover_identity message in
PD3, kernel may dump below warning:

---[ end trace 0000000000000000 ]---
Below sequences may trigger this warning:
tcpm_send_discover_work(work)
tcpm_send_vdm(port, USB_SID_PD, CMD_DISCOVER_IDENT, NULL, 0);
tcpm_queue_vdm(port, header, data, count);
port->vdm_state = VDM_STATE_READY;
vdm_state_machine_work(work);
<-- received discover_identity from partner
vdm_run_state_machine(port);
port->vdm_state = VDM_STATE_SEND_MESSAGE;
mod_vdm_delayed_work(port, x);
tcpm_pd_rx_handler(work);
tcpm_pd_data_request(port, msg);
tcpm_handle_vdm_request(port, msg->payload, cnt);
tcpm_queue_vdm(port, response[0], &response[1], rlen - 1);
--> WARN_ON(port->vdm_state > VDM_STATE_DONE);
For this case, the state machine could still send out discover
identity message later if we skip current discover_identity message.
So we should handle the received message firstly and override the pending
discover_identity message without warning in this case. Then, a delayed
send_discover work will send discover_identity message again.

</TASK>
The bug occurs when the dbAllocDmapLev()function attempts to access
dp->tree.stree[leafidx + LEAFIND] while the leafidx value is negative.
To rectify this, the patch introduces a safeguard within the
dbAllocDmapLev() function. A check has been added to verify if leafidx is
negative. If it is, the function immediately returns an I/O error, preventing
any further execution that could potentially cause harm.
Tested via syzbot.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/rtas_flash: allow user copy to flash block cache objects
With hardened usercopy enabled (CONFIG_HARDENED_USERCOPY=y), using the
/proc/powerpc/rtas/firmware_update interface to prepare a system
firmware update yields a BUG():
kernel BUG at mm/usercopy.c:102!

The blocks of the firmware image are copied directly from user memory
to objects allocated from flash_block_cache, so flash_block_cache must
be created using kmem_cache_create_usercopy() to mark it safe for user
access.

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: imx: clk-imx8mp: improve error handling in imx8mp_clocks_probe()
Replace of_iomap() and kzalloc() with devm_of_iomap() and devm_kzalloc()
which can automatically release the related memory when the device
or driver is removed or unloaded to avoid potential memory leak.
In this case, iounmap(anatop_base) in line 427,433 are removed
as manual release is not required.
Besides, referring to clk-imx8mq.c, check the return code of
of_clk_add_hw_provider, if it returns negtive, print error info
and unregister hws, which makes the program more robust.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xfrm: add NULL check in xfrm_update_ae_params
Normally, x->replay_esn and x->preplay_esn should be allocated at
xfrm_alloc_replay_state_esn(...) in xfrm_state_construct(...), hence the
xfrm_update_ae_params(...) is okay to update them. However, the current
implementation of xfrm_new_ae(...) allows a malicious user to directly
dereference a NULL pointer and crash the kernel like below.
BUG: kernel NULL pointer dereference, address: 0000000000000000

Summary
In the Linux kernel, the following vulnerability has been resolved:
video: fbdev: i740fb: Check the argument of i740_calc_vclk()
Since the user can control the arguments of the ioctl() from the user
space, under special arguments that may result in a divide-by-zero bug.
If the user provides an improper 'pixclock' value that makes the argumet
of i740_calc_vclk() less than 'I740_RFREQ_FIX', it will cause a
divide-by-zero bug in:
drivers/video/fbdev/i740fb.c:353 p_best = min(15, ilog2(I740_MAX_VCO_FREQ / (freq / I740_RFREQ_FIX)));
The following log can reveal it:
divide error: 0000 [#1] PREEMPT SMP KASAN PTI

Fix this by checking the argument of i740_calc_vclk() first.

Summary
In the Linux kernel, the following vulnerability has been resolved:
spmi: trace: fix stack-out-of-bound access in SPMI tracing functions
trace_spmi_write_begin() and trace_spmi_read_end() both call
memcpy() with a length of "len + 1". This leads to one extra
byte being read beyond the end of the specified buffer. Fix
this out-of-bound memory access by using a length of "len"
instead.
Here is a KASAN log showing the issue:

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: abort transaction on unexpected eb generation at btrfs_copy_root()
If we find an unexpected generation for the extent buffer we are cloning
at btrfs_copy_root(), we just WARN_ON() and don't error out and abort the
transaction, meaning we allow to persist metadata with an unexpected
generation. Instead of warning only, abort the transaction and return
-EUCLEAN.

No remote peer data or network protocol handler reaches `btrfs_copy_root()`.\nAC:L - Once the volume carries a tree block with a future generation \u2014 a state the attacker authors directly in a crafted image, or that pre-exists from bit rot or an earlier bug \u2014 the trigger is a single deterministic ioctl with no race to win and no memory layout to groom. The attacker controls both the on-disk state and the snapshot request, so nothing is beyond their influence.\nPR:L - `__btrfs_ioctl_snap_create()` gates snapshots only on `inode_owner_or_capable()` against the source subvolume, and plain subvolume creation is explicitly unrestricted, so any unprivileged user with write access to a btrfs mount can create a subvolume and then snapshot it to drive `create_pending_snapshot()` into `btrfs_copy_root()`.\nUI:N - The attacker issues the snapshot ioctl themselves against a filesystem that is already mounted, and the balance/relocation path likewise runs without any victim action. No one has to open a file or mount anything at exploitation time.\nS:U - The mishandled metadata, the corrupted extent tree, and the resulting crashes all stay within the kernel\u0027s own security authority on the same host; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Persisting the clone means the bogus-generation block later makes `btrfs_block_can_be_shared()` return false (`buf_gen \u003e btrfs_root_last_snapshot()`), so COW skips ref accounting for a block the new snapshot references; extents are subsequently freed while still in use and reallocated to other files, letting the attacker read data belonging to other users through their own subvolume.\nI:H - The kernel writes metadata it has already recognised as invalid, and the resulting extent-refcount divergence causes in-use blocks to be handed out to unrelated files \u2014 arbitrary, persistent corruption of other users\u0027 file contents and of filesystem metadata that survives reboot.\nA:H - The `WARN_ON()` alone is an immediate panic under `panic_on_warn`, and the corrupted metadata that gets committed makes later tree reads fail the parent-transid check, leaving the filesystem unmountable or forcing it read-only \u2014 a persistent denial of service the attacker can trigger at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: hisilicon/qm - set NULL to qm->debug.qm_diff_regs
When the initialization of qm->debug.acc_diff_reg fails,
the probe process does not exit. However, after qm->debug.qm_diff_regs is
freed, it is not set to NULL. This can lead to a double free when the
remove process attempts to free it again. Therefore, qm->debug.qm_diff_regs
should be set to NULL after it is freed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: adc: at91_adc: fix possible memory leak in at91_adc_allocate_trigger()
If iio_trigger_register() returns error, it should call iio_trigger_free()
to give up the reference that hold in iio_trigger_alloc(), so that it can
call iio_trig_release() to free memory when the refcount hit to 0.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/platform/uv: Use alternate source for socket to node data
The UV code attempts to build a set of tables to allow it to do
bidirectional socket<=>node lookups.
But when nr_cpus is set to a smaller number than actually present, the
cpu_to_node() mapping information for unused CPUs is not available to
build_socket_tables(). This results in skipping some nodes or sockets
when creating the tables and leaving some -1's for later code to trip.
over, causing oopses.
The problem is that the socket<=>node lookups are created by doing a
loop over all CPUs, then looking up the CPU's APICID and socket. But
if a CPU is not present, there is no way to start this lookup.
Instead of looping over all CPUs, take CPUs out of the equation
entirely. Loop over all APICIDs which are mapped to a valid NUMA node.
Then just extract the socket-id from the APICID.
This avoid tripping over disabled CPUs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: DPCM: Don't pick up BE without substream
When DPCM tries to add valid BE connections at dpcm_add_paths(), it
doesn't check whether the picked BE actually supports for the given
stream direction. Due to that, when an asymmetric BE stream is
present, it picks up wrongly and this may result in a NULL dereference
at a later point where the code assumes the existence of a
corresponding BE substream.
This patch adds the check for the presence of the substream for the
target BE for avoiding the problem above.
Note that we have already some fix for non-existing BE substream at
commit 6246f283d5e0 ("ASoC: dpcm: skip missing substream while
applying symmetry"). But the code path we've hit recently is rather
happening before the previous fix. So this patch tries to fix at
picking up a BE instead of parsing BE lists.

Summary
In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: Add validation before accessing cgx and lmac
with the addition of new MAC blocks like CN10K RPM and CN10KB
RPM_USX, LMACs are noncontiguous and CGX blocks are also
noncontiguous. But during RVU driver initialization, the driver
is assuming they are contiguous and trying to access
cgx or lmac with their id which is resulting in kernel panic.
This patch fixes the issue by adding proper checks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: iforce - invert valid length check when fetching device IDs
syzbot is reporting uninitialized value at iforce_init_device() [1], for
commit 6ac0aec6b0a6 ("Input: iforce - allow callers supply data buffer
when fetching device IDs") is checking that valid length is shorter than
bytes to read. Since iforce_get_id_packet() stores valid length when
returning 0, the caller needs to check that valid length is longer than or
equals to bytes to read.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Wait for io return on terminate rport
System crash due to use after free.
Current code allows terminate_rport_io to exit before making
sure all IOs has returned. For FCP-2 device, IO's can hang
on in HW because driver has not tear down the session in FW at
first sign of cable pull. When dev_loss_tmo timer pops,
terminate_rport_io is called and upper layer is about to
free various resources. Terminate_rport_io trigger qla to do
the final cleanup, but the cleanup might not be fast enough where it
leave qla still holding on to the same resource.
Wait for IO's to return to upper layer before resources are freed.

An attacker on the same FC fabric can force that loss without Internet-wide reachability, so Adjacent is the correct vector.\nAC:L - A fabric-adjacent attacker can induce remote-port loss while I/O is outstanding against an FCP-2 target; the FCP-2 hang-until-terminate behavior is a deterministic driver path, not a condition outside attacker influence. Missing the wait makes the UAF reliably follow that sequence.\nPR:N - Remote-port deletion and the subsequent terminate_rport_io callback are driven by FC fabric/link events processed in the host driver with no host authentication or privilege check. No local account or capability on the victim host is required.\nUI:N - After port loss, the FC transport automatically runs the dev_loss_tmo/fast_io_fail timers and calls terminate_rport_io without any user action such as mounting a filesystem or opening a device.\nS:U - The vulnerability corrupts and crashes the host kernel that owns the qla2xxx driver. It does not cross a VM, IOMMU, or other separate security authority boundary.\nC:H - The commit documents a use-after-free on resources still referenced by outstanding I/O after the upper layer frees them. Per kernel UAF guidance, that enables disclosure of freed-object contents via heap reuse.\nI:H - The same use-after-free on SCSI/command path structures can be leveraged for heap shaping and arbitrary write or control-flow hijacking once the freed object is reclaimed.\nA:H - The fix explicitly addresses a system crash from the use-after-free when straggling I/Os complete against freed resources, so availability impact is a kernel oops/panic."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: 8852a: rfk: fix div 0 exception
The DPK is a kind of RF calibration whose algorithm is to fine tune
parameters and calibrate, and check the result. If the result isn't good
enough, it could adjust parameters and try again.
This issue is to read and show the result, but it could be a negative
calibration result that causes divisor 0 and core dump. So, fix it by
phy_div() that does division only if divisor isn't zero; otherwise,
zero is adopted.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mtd: rawnand: brcmnand: Fix potential out-of-bounds access in oob write
When the oob buffer length is not in multiple of words, the oob write
function does out-of-bounds read on the oob source buffer at the last
iteration. Fix that by always checking length limit on the oob buffer
read and fill with 0xff when reaching the end of the buffer to the oob
registers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/amd/iommu_v2: Fix pasid_state refcount dec hit 0 warning on pasid unbind
When unbinding pasid - a race condition exists vs outstanding page faults.
To prevent this, the pasid_state object contains a refcount.
* set to 1 on pasid bind
* incremented on each ppr notification start
* decremented on each ppr notification done
* decremented on pasid unbind
Since refcount_dec assumes that refcount will never reach 0:
the current implementation causes the following to be invoked on
pasid unbind:
REFCOUNT_WARN("decrement hit 0; leaking memory")
Fix this issue by changing refcount_dec to refcount_dec_and_test
to explicitly handle refcount=1.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Drivers: hv: vmbus: Don't dereference ACPI root object handle
Since the commit referenced in the Fixes: tag below the VMBus client driver
is walking the ACPI namespace up from the VMBus ACPI device to the ACPI
namespace root object trying to find Hyper-V MMIO ranges.
However, if it is not able to find them it ends trying to walk resources of
the ACPI namespace root object itself.
This object has all-ones handle, which causes a NULL pointer dereference
in the ACPI code (from dereferencing this pointer with an offset).
This in turn causes an oops on boot with VMBus host implementations that do
not provide Hyper-V MMIO ranges in their VMBus ACPI device or its
ancestors.
The QEMU VMBus implementation is an example of such implementation.
I guess providing these ranges is optional, since all tested Windows
versions seem to be able to use VMBus devices without them.
Fix this by explicitly terminating the lookup at the ACPI namespace root
object.
Note that Linux guests under KVM/QEMU do not use the Hyper-V PV interface
by default - they only do so if the KVM PV interface is missing or
disabled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bridge: switchdev: Fix memory leaks when changing VLAN protocol
The bridge driver can offload VLANs to the underlying hardware either
via switchdev or the 8021q driver. When the former is used, the VLAN is
marked in the bridge driver with the 'BR_VLFLAG_ADDED_BY_SWITCHDEV'
private flag.
To avoid the memory leaks mentioned in the cited commit, the bridge
driver will try to delete a VLAN via the 8021q driver if the VLAN is not
marked with the previously mentioned flag.
When the VLAN protocol of the bridge changes, switchdev drivers are
notified via the 'SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL' attribute, but
the 8021q driver is also called to add the existing VLANs with the new
protocol and delete them with the old protocol.
In case the VLANs were offloaded via switchdev, the above behavior is
both redundant and buggy. Redundant because the VLANs are already
programmed in hardware and drivers that support VLAN protocol change
(currently only mlx5) change the protocol upon the switchdev attribute
notification. Buggy because the 8021q driver is called despite these
VLANs being marked with 'BR_VLFLAG_ADDED_BY_SWITCHDEV'. This leads to
memory leaks [1] when the VLANs are deleted.
Fix by not calling the 8021q driver for VLANs that were already
programmed via switchdev.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sunrpc: fix potential memory leaks in rpc_sysfs_xprt_state_change()
The issue happens on some error handling paths. When the function
fails to grab the object `xprt`, it simply returns 0, forgetting to
decrease the reference count of another object `xps`, which is
increased by rpc_sysfs_xprt_kobj_get_xprt_switch(), causing refcount
leaks. Also, the function forgets to check whether `xps` is valid
before using it, which may result in NULL-dereferencing issues.
Fix it by adding proper error handling code when either `xprt` or
`xps` is NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
watchdog: sp5100_tco: Fix a memory leak of EFCH MMIO resource
Unlike release_mem_region(), a call to release_resource() does not
free the resource, so it has to be freed explicitly to avoid a memory
leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bcache: Fix __bch_btree_node_alloc to make the failure behavior consistent
In some specific situations, the return value of __bch_btree_node_alloc
may be NULL. This may lead to a potential NULL pointer dereference in
caller function like a calling chain :
btree_split->bch_btree_node_alloc->__bch_btree_node_alloc.
Fix it by initializing the return value in __bch_btree_node_alloc.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ppp: fix race conditions in ppp_fill_forward_path
ppp_fill_forward_path() has two race conditions:
1. The ppp->channels list can change between list_empty() and
list_first_entry(), as ppp_lock() is not held. If the only channel
is deleted in ppp_disconnect_channel(), list_first_entry() may
access an empty head or a freed entry, and trigger a panic.
2. pch->chan can be NULL. When ppp_unregister_channel() is called,
pch->chan is set to NULL before pch is removed from ppp->channels.
Fix these by using a lockless RCU approach:
- Use list_first_or_null_rcu() to safely test and access the first list
entry.
- Convert list modifications on ppp->channels to their RCU variants and
add synchronize_net() after removal.
- Check for a NULL pch->chan before dereferencing it.

Per kernel CNA guidance, tc/qdisc paths reachable via user namespaces are PR:L, not PR:H.\nUI:N - The attacker performs the entire sequence (create qdisc/class, repeatedly issue the failing filter add, delete the class, send traffic) unaided.

Per guidance, a UAF that grants control over freed-object contents is High confidentiality impact.\nI:H - The same use-after-free lets a sprayed replacement object supply `cl-\u003elevel`, `cl-\u003eleaf.q` and the qdisc function pointers dereferenced in the enqueue path, yielding a write/control-flow-hijack primitive \u2014 the same primitive that produced working local privilege escalation for the sibling cls_u32 tcf_result bugs. Type-confused/UAF corruption of kernel objects is High integrity impact.\nA:H - Even without exploitation, the leaked `filter_cnt` permanently pins the class and its qdisc so `tc class del` always returns `-EBUSY` and the memory is never reclaimed, and the dangling `res.class` dereference in the packet enqueue path oopses the kernel. Any kernel crash or use-after-free is High availability impact."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ata: libata-transport: fix error handling in ata_tdev_add()
In ata_tdev_add(), the return value of transport_add_device() is
not checked. As a result, it causes null-ptr-deref while removing
the module, because transport_remove_device() is called to remove
the device that was not added.
Unable to handle kernel NULL pointer dereference at virtual address 00000000000000d0
CPU: 13 PID: 13603 Comm: rmmod Kdump: loaded Tainted: G W 6.1.0-rc3+ #36

Fix this by checking and handling return value of transport_add_device()
in ata_tdev_add(). In the error path, device_del() is called to delete
the device which was added earlier in this function, and ata_tdev_free()
is called to free ata_dev.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ip_vti: fix potential slab-use-after-free in decode_session6
When ip_vti device is set to the qdisc of the sfb type, the cb field
of the sent skb may be modified during enqueuing. Then,
slab-use-after-free may occur when ip_vti device sends IPv6 packets.
As commit f855691975bb ("xfrm6: Fix the nexthdr offset in
_decode_session6.") showed, xfrm_decode_session was originally intended
only for the receive path. IP6CB(skb)->nhoff is not set during
transmission. Therefore, set the cb field in the skb to 0 before
sending packets.

Although forwarded traffic from a remote peer would also hit vti_tunnel_xmit on a router so configured, the vulnerable state depends entirely on local device/qdisc configuration, so Local is the defensible vector.\nAC:L - The attacker creates every precondition: the vti device, the sfb qdisc, and its rehash_interval/warmup_time tunables that control when q-\u003eslot flips and hashes[1] is populated with a siphash value overlapping IP6CB-\u003enhoff. Once slot==1 every transmitted IPv6 packet performs the wild nh[nhoff] read, making the trigger deterministic and repeatable.\nPR:L - Creating the vti tunnel and attaching the sfb qdisc requires CAP_NET_ADMIN, but ip_vti is fully network-namespace aware (register_pernet_device with a per-netns ip_vti0 fallback), so an unprivileged user obtains the needed capability with unshare -Urn. Per kernel scoring guidance, CAP_NET_ADMIN reachable through user namespaces is Low, not High.\nUI:N - The attacker performs the entire sequence \u2014 configure the device and qdisc, add a route, send an IPv6 packet \u2014 with no action by any other user or administrator.\nS:U - The out-of-bounds access occurs in kernel heap memory and its consequences remain within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - decode_session6() reads a byte from freed or adjacent slab memory at an offset up to 64KB beyond the network header \u2014 an unbounded use-after-free read rather than a small bounded one \u2014 and that value steers the protocol state machine and xfrm flow key, providing an oracle on kernel heap contents.\nI:H - The kernel\u0027s IPsec flow decode (flowi6_proto, ports, and the ensuing ip6_route_output/xfrm_lookup_route policy selection) is driven by data read out of freed heap memory, so a security-relevant kernel decision is made on corrupted state; consistent with treating slab-use-after-free as a high integrity impact.\nA:H - The wild read dereferences an address up to 65535 bytes past the skb data allocation, which faults on unmapped memory or memory holes and reliably produces a KASAN slab-use-after-free splat and kernel oops. The attacker can repeat it on every transmitted packet, so it is a sustained crash/DoS."

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: j1939: implement NETDEV_UNREGISTER notification handler
syzbot is reporting
unregister_netdevice: waiting for vcan0 to become free. Usage count = 2
problem, for j1939 protocol did not have NETDEV_UNREGISTER notification
handler for undoing changes made by j1939_sk_bind().
Commit 25fe97cb7620 ("can: j1939: move j1939_priv_put() into sk_destruct
callback") expects that a call to j1939_priv_put() can be unconditionally
delayed until j1939_sk_sock_destruct() is called. But we need to call
j1939_priv_put() against an extra ref held by j1939_sk_bind() call
(as a part of undoing changes made by j1939_sk_bind()) as soon as
NETDEV_UNREGISTER notification fires (i.e. before j1939_sk_sock_destruct()
is called via j1939_sk_release()). Otherwise, the extra ref on "struct
j1939_priv" held by j1939_sk_bind() call prevents "struct net_device" from
dropping the usage count to 1; making it impossible for
unregister_netdevice() to continue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: fix use-after-free in cmp_bss()
Following bss_free() quirk introduced in commit 776b3580178f
("cfg80211: track hidden SSID networks properly"), adjust
cfg80211_update_known_bss() to free the last beacon frame
elements only if they're not shared via the corresponding
'hidden_beacon_bss' pointer.

Per kernel guidance, WiFi frame injection is Adjacent.\nAC:L - The attacker controls every precondition: SSID hiding, BSSID, the two channels, the beacon/probe-response pairs that build the hidden groups, and the CSA that fires `cfg80211_update_assoc_bss_entry()`; the victim\u0027s routine background scans supply the rest without attacker effort. The freed object\u0027s size is attacker-chosen via IE length, so heap grooming is also under attacker control.\nPR:N - No credentials or account on the target system are needed; beacons, probe responses and public action frames are unauthenticated and unprotected (beacon protection/BIGTK is rarely deployed), so a rogue AP or frame injector reaches the code with zero privileges.\nUI:N - Scanning, beacon processing and CSA handling are performed automatically by the kernel for an associated STA \u2014 no user action is required, and the attacker can spoof the legitimate AP\u0027s frames against an already-connected victim.\nS:U - The freed `cfg80211_bss_ies` allocation and all corrupted state live in the kernel\u0027s own slab and cfg80211 BSS list; no VM, IOMMU or sandbox boundary is crossed.\nC:H - The stale `beacon_ies`/`ies` pointers are read by `cmp_bss()` and, critically, copied wholesale to userspace via `NL80211_BSS_BEACON_IES` in scan dumps, disclosing reallocated freed heap contents \u2014 and an attacker-controlled `len` after reallocation extends this to a large out-of-bounds kernel memory read.\nI:H - The shared IEs are freed while still owned by the beacon BSS, so the later `bss_free()` performs a second `kfree_rcu()` on the same object \u2014 a double free of an attacker-sized allocation, a well-established primitive for arbitrary write and control-flow hijack; freed-memory contents also drive rb-tree ordering decisions.\nA:H - Use-after-free reads in `cmp_bss()` plus the subsequent double free corrupt the slab allocator and reliably produce oopses/panics, and the condition can be re-triggered at will by an in-range attacker."

Summary
In the Linux kernel, the following vulnerability has been resolved:
gfs2: Fix possible data races in gfs2_show_options()
Some fields such as gt_logd_secs of the struct gfs2_tune are accessed
without holding the lock gt_spin in gfs2_show_options():
val = sdp->sd_tune.gt_logd_secs;
if (val != 30)
seq_printf(s, ",commit=%d", val);
And thus can cause data races when gfs2_show_options() and other functions
such as gfs2_reconfigure() are concurrently executed:
spin_lock(>->gt_spin);
gt->gt_logd_secs = newargs->ar_commit;
To fix these possible data races, the lock sdp->sd_tune.gt_spin is
acquired before accessing the fields of gfs2_tune and released after these
accesses.
Further changes by Andreas:
- Don't hold the spin lock over the seq_printf operations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iavf: fix hang on reboot with ice
When a system with E810 with existing VFs gets rebooted the following
hang may be observed.
Pid 1 is hung in iavf_remove(), part of a network driver:

During reboot all drivers PM shutdown callbacks are invoked.
In iavf_shutdown() the adapter state is changed to __IAVF_REMOVE.
In ice_shutdown() the call chain above is executed, which at some point
calls iavf_remove(). However iavf_remove() expects the VF to be in one
of the states __IAVF_RUNNING, __IAVF_DOWN or __IAVF_INIT_FAILED. If
that's not the case it sleeps forever.
So if iavf_shutdown() gets invoked before iavf_remove() the system will
hang indefinitely because the adapter is already in state __IAVF_REMOVE.
Fix this by returning from iavf_remove() if the state is __IAVF_REMOVE,
as we already went through iavf_shutdown().

Summary
In the Linux kernel, the following vulnerability has been resolved:
sch_hfsc: Fix qlen accounting bug when using peek in hfsc_enqueue()
When enqueuing the first packet to an HFSC class, hfsc_enqueue() calls the
child qdisc's peek() operation before incrementing sch->q.qlen and
sch->qstats.backlog. If the child qdisc uses qdisc_peek_dequeued(), this may
trigger an immediate dequeue and potential packet drop. In such cases,
qdisc_tree_reduce_backlog() is called, but the HFSC qdisc's qlen and backlog
have not yet been updated, leading to inconsistent queue accounting. This
can leave an empty HFSC class in the active list, causing further
consequences like use-after-free.
This patch fixes the bug by moving the increment of sch->q.qlen and
sch->qstats.backlog before the call to the child qdisc's peek() operation.
This ensures that queue length and backlog are always accurate when packet
drops or dequeues are triggered during the peek.

If the child qdisc uses qdisc_peek_dequeued(), this may\ntrigger an immediate dequeue and potential packet drop. In such cases,\nqdisc_tree_reduce_backlog() is called, but the HFSC qdisc\u0027s qlen and backlog\nhave not yet been updated, leading to inconsistent queue accounting. This\ncan leave an empty HFSC class in the active list, causing further\nconsequences like use-after-free.\n\nThis patch fixes the bug by moving the increment of sch-\u003eq.qlen and\nsch-\u003eqstats.backlog before the call to the child qdisc\u0027s peek() operation.\nThis ensures that queue length and backlog are always accurate when packet\ndrops or dequeues are triggered during the peek."

Per kernel scoring guidance, tc/netlink qdisc configuration is a local attack vector.\nAC:L - The attacker fully controls both the qdisc hierarchy (hfsc + netem with an inner qdisc that rejects on enqueue) and the packet that drives hfsc_enqueue(), so the peek-time drop and the resulting qlen underflow are triggered deterministically with no race to win and no reliance on uncontrolled state.\nPR:L - Qdisc configuration is gated by netlink_net_capable(CAP_NET_ADMIN) against the netns owning user_ns, which any unprivileged user obtains via `unshare -Urn` and then applies to lo/dummy/veth inside the namespace. No real root in the init namespace is needed.\nUI:N - The attacker performs the qdisc setup and generates the triggering traffic entirely on their own; no victim action or interaction is required.\nS:U - The corruption is confined to kernel scheduler state in the same security authority; it is a standard local kernel privilege escalation with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The accounting inconsistency leaves a freed/empty hfsc_class linked in the eligible and vt-trees, and the commit explicitly states this leads to use-after-free; a UAF on a ~512-byte generic-kmalloc object with embedded rb_nodes yields a controlled read primitive over sprayed kernel objects.\nI:H - Dangling rb_node linkage of a freed hfsc_class means subsequent eltree/vttree insert, update, and rebalance operations write attacker-influenced values into reclaimed heap memory, giving a write primitive suitable for control-flow hijacking and privilege escalation.\nA:H - Even without full exploitation, the q.qlen/backlog underflow to 0xFFFFFFFF and the stale active-list entry cause use-after-free oopses, KASAN splats, and reported infinite loops in hfsc_dequeue(), crashing or hanging the machine."

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: dvb-frontends: w7090p: fix null-ptr-deref in w7090p_tuner_write_serpar and w7090p_tuner_read_serpar
In w7090p_tuner_write_serpar, msg is controlled by user. When msg[0].buf is null and msg[0].len is zero, former checks on msg[0].buf would be passed. If accessing msg[0].buf[2] without sanity check, null pointer deref would happen. We add
check on msg[0].len to prevent crash.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/bnxt_re: wraparound mbox producer index
Driver is not handling the wraparound of the mbox producer index correctly.
Currently the wraparound happens once u32 max is reached.
Bit 31 of the producer index register is special and should be set
only once for the first command. Because the producer index overflow
setting bit31 after a long time, FW goes to initialization sequence
and this causes FW hang.
Fix is to wraparound the mbox producer index once it reaches u16 max.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tty: n_gsm: add sanity check for gsm->receive in gsm_receive_buf()
A null pointer dereference can happen when attempting to access the
"gsm->receive()" function in gsmld_receive_buf(). Currently, the code
assumes that gsm->recieve is only called after MUX activation.
Since the gsmld_receive_buf() function can be accessed without the need to
initialize the MUX, the gsm->receive() function will not be set and a
NULL pointer dereference will occur.
Fix this by avoiding the call to "gsm->receive()" in case the function is
not initialized by adding a sanity check.
Call Trace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: fix mid leak during reconnection after timeout threshold
When the number of responses with status of STATUS_IO_TIMEOUT
exceeds a specified threshold (NUM_STATUS_IO_TIMEOUT), we reconnect
the connection. But we do not return the mid, or the credits
returned for the mid, or reduce the number of in-flight requests.
This bug could result in the server->in_flight count to go bad,
and also cause a leak in the mids.
This change moves the check to a few lines below where the
response is decrypted, even of the response is read from the
transform header. This way, the code for returning the mids
can be reused.
Also, the cifs_reconnect was reconnecting just the transport
connection before. In case of multi-channel, this may not be
what we want to do after several timeouts. Changed that to
reconnect the session and the tree too.
Also renamed NUM_STATUS_IO_TIMEOUT to a more appropriate name
MAX_STATUS_IO_TIMEOUT.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: intel-ish-hid: ipc: Fix potential use-after-free in work function
When a reset notify IPC message is received, the ISR schedules a work
function and passes the ISHTP device to it via a global pointer
ishtp_dev. If ish_probe() fails, the devm-managed device resources
including ishtp_dev are freed, but the work is not cancelled, causing a
use-after-free when the work function tries to access ishtp_dev. Use
devm_work_autocancel() instead, so that the work is automatically
cancelled if probe fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
kprobes: Skip clearing aggrprobe's post_handler in kprobe-on-ftrace case
In __unregister_kprobe_top(), if the currently unregistered probe has
post_handler but other child probes of the aggrprobe do not have
post_handler, the post_handler of the aggrprobe is cleared. If this is
a ftrace-based probe, there is a problem. In later calls to
disarm_kprobe(), we will use kprobe_ftrace_ops because post_handler is
NULL. But we're armed with kprobe_ipmodify_ops. This triggers a WARN in
__disarm_kprobe_ftrace() and may even cause use-after-free:
Failed to disarm kprobe-ftrace at kernel_clone+0x0/0x3c0 (error -2)
WARNING: CPU: 5 PID: 137 at kernel/kprobes.c:1135 __disarm_kprobe_ftrace.isra.21+0xcf/0xe0
Modules linked in: testKprobe_007(-)

[...]
For the kprobe-on-ftrace case, we keep the post_handler setting to
identify this aggrprobe armed with kprobe_ipmodify_ops. This way we
can disarm it correctly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev/ep93xx-fb: Do not assign to struct fb_info.dev
Do not assing the Linux device to struct fb_info.dev. The call to
register_framebuffer() initializes the field to the fbdev device.
Drivers should not override its value.
Fixes a bug where the driver incorrectly decreases the hardware
device's reference counter and leaks the fbdev device.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: When HCI work queue is drained, only queue chained work
The HCI command, event, and data packet processing workqueue is drained
to avoid deadlock in commit
76727c02c1e1 ("Bluetooth: Call drain_workqueue() before resetting state").
There is another delayed work, which will queue command to this drained
workqueue. Which results in the following error report:
Bluetooth: hci2: command 0x040f tx timeout

To fix this, we can add a new HCI_DRAIN_WQ flag, and don't queue the
timeout workqueue while command workqueue is draining.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm raid: fix address sanitizer warning in raid_status
There is this warning when using a kernel with the address sanitizer
and running this testsuite:
https://gitlab.com/cki-project/kernel-tests/-/tree/main/storage/swraid/scsi_raid
==================================================================
BUG: KASAN: slab-out-of-bounds in raid_status+0x1747/0x2820 [dm_raid]

The warning is caused by reading conf->max_nr_stripes in raid_status. The
code in raid_status reads mddev->private, casts it to struct r5conf and
reads the entry max_nr_stripes.
However, if we have different raid type than 4/5/6, mddev->private
doesn't point to struct r5conf; it may point to struct r0conf, struct
r1conf, struct r10conf or struct mpconf. If we cast a pointer to one
of these structs to struct r5conf, we will be reading invalid memory
and KASAN warns about it.
Fix this bug by reading struct r5conf only if raid type is 4, 5 or 6.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ARM: bcm: Fix refcount leak in bcm_kona_smc_init
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ring-buffer: Check for NULL cpu_buffer in ring_buffer_wake_waiters()
On some machines the number of listed CPUs may be bigger than the actual
CPUs that exist. The tracing subsystem allocates a per_cpu directory with
access to the per CPU ring buffer via a cpuX file. But to save space, the
ring buffer will only allocate buffers for online CPUs, even though the
CPU array will be as big as the nr_cpu_ids.
With the addition of waking waiters on the ring buffer when closing the
file, the ring_buffer_wake_waiters() now needs to make sure that the
buffer is allocated (with the irq_work allocated with it) before trying to
wake waiters, as it will cause a NULL pointer dereference.
While debugging this, I added a NULL check for the buffer itself (which is
OK to do), and also NULL pointer checks against buffer->buffers (which is
not fine, and will WARN) as well as making sure the CPU number passed in
is within the nr_cpu_ids (which is also not fine if it isn't).

Summary
In the Linux kernel, the following vulnerability has been resolved:
tty: n_gsm: fix deadlock and link starvation in outgoing data path
The current implementation queues up new control and user packets as needed
and processes this queue down to the ldisc in the same code path.
That means that the upper and the lower layer are hard coupled in the code.
Due to this deadlocks can happen as seen below while transmitting data,
especially during ldisc congestion. Furthermore, the data channels starve
the control channel on high transmission load on the ldisc.
Introduce an additional control channel data queue to prevent timeouts and
link hangups during ldisc congestion. This is being processed before the
user channel data queue in gsm_data_kick(), i.e. with the highest priority.
Put the queue to ldisc data path into a workqueue and trigger it whenever
new data has been put into the transmission queue. Change
gsm_dlci_data_sweep() accordingly to fill up the transmission queue until
TX_THRESH_HI. This solves the locking issue, keeps latency low and provides
good performance on high data load.
Note that now all packets from a DLCI are removed from the internal queue
if the associated DLCI was closed. This ensures that no data is sent by the
introduced write task to an already closed DLCI.

This ensures that no data is sent by the\nintroduced write task to an already closed DLCI.\n\nBUG: spinlock recursion on CPU#0, test_v24_loop/124\n lock: serial8250_ports+0x3a8/0x7500, .magic: dead4ead, .owner: test_v24_loop/124, .owner_cpu: 0\nCPU: 0 PID: 124 Comm: test_v24_loop Tainted: G O 5.18.0-rc2 #3\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014\nCall Trace:\n \u003cIRQ\u003e\n dump_stack_lvl+0x34/0x44\n do_raw_spin_lock+0x76/0xa0\n _raw_spin_lock_irqsave+0x72/0x80\n uart_write_room+0x3b/0xc0\n gsm_data_kick+0x14b/0x240 [n_gsm]\n gsmld_write_wakeup+0x35/0x70 [n_gsm]\n tty_wakeup+0x53/0x60\n tty_port_default_wakeup+0x1b/0x30\n serial8250_tx_chars+0x12f/0x220\n serial8250_handle_irq.part.0+0xfe/0x150\n serial8250_default_handle_irq+0x48/0x80\n serial8250_interrupt+0x56/0xa0\n __handle_irq_event_percpu+0x78/0x1f0\n handle_irq_event+0x34/0x70\n handle_fasteoi_irq+0x90/0x1e0\n __common_interrupt+0x69/0x100\n common_interrupt+0x48/0xc0\n asm_common_interrupt+0x1e/0x40\nRIP: 0010:__do_softirq+0x83/0x34e\nCode: 2a 0a ff 0f b7 ed c7 44 24 10 0a 00 00 00 48 c7 c7 51 2a 64 82 e8 2d\ne2 d5 ff 65 66 c7 05 83 af 1e 7e 00 00 fb b8 ff ff ff ff \u003c49\u003e c7 c2 40 61\n80 82 0f bc c5 41 89 c4 41 83 c4 01 0f 84 e6 00 00\nRSP: 0018:ffffc90000003f98 EFLAGS: 00000286\nRAX: 00000000ffffffff RBX: 0000000000000000 RCX: 0000000000000000\nRDX: 0000000000000000 RSI: ffffffff82642a51 RDI: ffffffff825bb5e7\nRBP: 0000000000000200 R08: 00000008de3271a8 R09: 0000000000000000\nR10: 0000000000000001 R11: 0000000000000000 R12: 0000000000000000\nR13: 0000000000000030 R14: 0000000000000000 R15: 0000000000000000\n ? __do_softirq+0x73/0x34e\n irq_exit_rcu+0xb5/0x100\n common_interrupt+0xa4/0xc0\n \u003c/IRQ\u003e\n \u003cTASK\u003e\n asm_common_interrupt+0x1e/0x40\nRIP: 0010:_raw_spin_unlock_irqrestore+0x2e/0x50\nCode: 00 55 48 89 fd 48 83 c7 18 53 48 89 f3 48 8b 74 24 10 e8 85 28 36 ff\n48 89 ef e8 cd 58 36 ff 80 e7 02 74 01 fb bf 01 00 00 00 \u003ce8\u003e 3d 97 33 ff\n65 8b 05 96 23 2b 7e 85 c0 74 03 5b 5d c3 0f 1f 44\nRSP: 0018:ffffc9000020fd08 EFLAGS: 00000202\nRAX: 0000000000000000 RBX: 0000000000000246 RCX: 0000000000000000\nRDX: 0000000000000004 RSI: ffffffff8257fd74 RDI: 0000000000000001\nRBP: ffff8880057de3a0 R08: 00000008de233000 R09: 0000000000000000\nR10: 0000000000000001 R11: 0000000000000000 R12: 0000000000000000\nR13: 0000000000000100 R14: 0000000000000202 R15: ffff8880057df0b8\n ? _raw_spin_unlock_irqrestore+0x23/0x50\n gsmtty_write+0x65/0x80 [n_gsm]\n n_tty_write+0x33f/0x530\n ? swake_up_all+0xe0/0xe0\n file_tty_write.constprop.0+0x1b1/0x320\n ? n_tty_flush_buffer+0xb0/0xb0\n new_sync_write+0x10c/0x190\n vfs_write+0x282/0x310\n ksys_write+0x68/0xe0\n do_syscall_64+0x3b/0x90\n entry_SYSCALL_64_after_hwframe+0x44/0xae\nRIP: 0033:0x7f3e5e35c15c\nCode: 8b 7c 24 08 89 c5 e8 c5 ff ff ff 89 ef 89 44 24\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: zero i_disksize when initializing the bootloader inode
If the boot loader inode has never been used before, the
EXT4_IOC_SWAP_BOOT inode will initialize it, including setting the
i_size to 0. However, if the "never before used" boot loader has a
non-zero i_size, then i_disksize will be non-zero, and the
inconsistency between i_size and i_disksize can trigger a kernel
warning:
WARNING: CPU: 0 PID: 2580 at fs/ext4/file.c:319
CPU: 0 PID: 2580 Comm: bb Not tainted 6.3.0-rc1-00004-g703695902cfa
RIP: 0010:ext4_file_write_iter+0xbc7/0xd10
Call Trace:
vfs_write+0x3b1/0x5c0
ksys_write+0x77/0x160
__x64_sys_write+0x22/0x30
do_syscall_64+0x39/0x80
Reproducer:
1. create corrupted image and mount it:
mke2fs -t ext4 /tmp/foo.img 200
debugfs -wR "sif <5> size 25700" /tmp/foo.img
mount -t ext4 /tmp/foo.img /mnt
cd /mnt
echo 123 > file
2. Run the reproducer program:
posix_memalign(&buf, 1024, 1024)
fd = open("file", O_RDWR | O_DIRECT);
ioctl(fd, EXT4_IOC_SWAP_BOOT);
write(fd, buf, 1024);
Fix this by setting i_disksize as well as i_size to zero when
initiaizing the boot loader inode.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Check for NOT_READY flag state after locking
Currently the check for NOT_READY flag is performed before obtaining the
necessary lock. This opens a possibility for race condition when the flow
is concurrently removed from unready_flows list by the workqueue task,
which causes a double-removal from the list and a crash[0]. Fix the issue
by moving the flag check inside the section protected by
uplink_priv->unready_flows_lock mutex.

Summary
In the Linux kernel, the following vulnerability has been resolved:
octeon_ep: cancel queued works in probe error path
If it fails to get the devices's MAC address, octep_probe exits while
leaving the delayed work intr_poll_task queued. When the work later
runs, it's a use after free.
Move the cancelation of intr_poll_task from octep_remove into
octep_device_cleanup. This does not change anything in the octep_remove
flow, but octep_device_cleanup is called also in the octep_probe error
path, where the cancelation is needed.
Note that the cancelation of ctrl_mbox_task has to follow
intr_poll_task's, because the ctrl_mbox_task may be queued by
intr_poll_task.

Summary
In the Linux kernel, the following vulnerability has been resolved:
jfs: upper bound check of tree index in dbAllocAG
When computing the tree index in dbAllocAG, we never check if we are
out of bounds realative to the size of the stree.
This could happen in a scenario where the filesystem metadata are
corrupted.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfc: nfcmrvl: Fix potential memory leak in nfcmrvl_i2c_nci_send()
nfcmrvl_i2c_nci_send() will be called by nfcmrvl_nci_send(), and skb
should be freed in nfcmrvl_i2c_nci_send(). However, nfcmrvl_nci_send()
will only free skb when i2c_master_send() return >=0, which means skb
will memleak when i2c_master_send() failed. Free skb no matter whether
i2c_master_send() succeeds.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: s390/diag: fix racy access of physical cpu number in diag 9c handler
We do check for target CPU == -1, but this might change at the time we
are going to use it. Hold the physical target CPU in a local variable to
avoid out-of-bound accesses to the cpu arrays.

After commit e6d5dbdd20aa ("xdp: add multi-buff support for xdp running in
generic mode"), the original skb may be freed in skb_pp_cow_data() when
XDP program was attached, which was allocated in tun_napi_alloc_frags().
However, the napi->skb still point to the original skb, update it after
XDP process.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: xhci_plat_remove: avoid NULL dereference
Since commit 4736ebd7fcaff1eb8481c140ba494962847d6e0a ("usb: host:
xhci-plat: omit shared hcd if either root hub has no ports")
xhci->shared_hcd can be NULL, which causes the following Oops

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Return the firmware result upon destroying QP/RQ
Previously when destroying a QP/RQ, the result of the firmware
destruction function was ignored and upper layers weren't informed
about the failure.
Which in turn could lead to various problems since when upper layer
isn't aware of the failure it continues its operation thinking that the
related QP/RQ was successfully destroyed while it actually wasn't,
which could lead to the below kernel WARN.
Currently, we return the correct firmware destruction status to upper
layers which in case of the RQ would be mlx5_ib_destroy_wq() which
was already capable of handling RQ destruction failure or in case of
a QP to destroy_qp_common(), which now would actually warn upon qp
destruction failure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
comedi: Fix use of uninitialized memory in do_insn_ioctl() and do_insnlist_ioctl()
syzbot reports a KMSAN kernel-infoleak in `do_insn_ioctl()`. A kernel
buffer is allocated to hold `insn->n` samples (each of which is an
`unsigned int`). For some instruction types, `insn->n` samples are
copied back to user-space, unless an error code is being returned. The
problem is that not all the instruction handlers that need to return
data to userspace fill in the whole `insn->n` samples, so that there is
an information leak. There is a similar syzbot report for
`do_insnlist_ioctl()`, although it does not have a reproducer for it at
the time of writing.
One culprit is `insn_rw_emulate_bits()` which is used as the handler for
`INSN_READ` or `INSN_WRITE` instructions for subdevices that do not have
a specific handler for that instruction, but do have an `INSN_BITS`
handler. For `INSN_READ` it only fills in at most 1 sample, so if
`insn->n` is greater than 1, the remaining `insn->n - 1` samples copied
to userspace will be uninitialized kernel data.
Another culprit is `vm80xx_ai_insn_read()` in the "vm80xx" driver. It
never returns an error, even if it fails to fill the buffer.
Fix it in `do_insn_ioctl()` and `do_insnlist_ioctl()` by making sure
that uninitialized parts of the allocated buffer are zeroed before
handling each instruction.
Thanks to Arnaud Lecomte for their fix to `do_insn_ioctl()`. That fix
replaced the call to `kmalloc_array()` with `kcalloc()`, but it is not
always necessary to clear the whole buffer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/tests: helpers: Avoid a driver uaf
when using __drm_kunit_helper_alloc_drm_device() the driver may be
dereferenced by device-managed resources up until the device is
freed, which is typically later than the kunit-managed resource code
frees it. Fix this by simply make the driver device-managed as well.
In short, the sequence leading to the UAF is as follows:
INIT:
Code allocates a struct device as a kunit-managed resource.
Code allocates a drm driver as a kunit-managed resource.
Code allocates a drm device as a device-managed resource.
EXIT:
Kunit resource cleanup frees the drm driver
Kunit resource cleanup puts the struct device, which starts a
device-managed resource cleanup
device-managed cleanup calls drm_dev_put()
drm_dev_put() dereferences the (now freed) drm driver -> Boom.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netem: Update sch->q.qlen before qdisc_tree_reduce_backlog()
qdisc_tree_reduce_backlog() notifies parent qdisc only if child
qdisc becomes empty, therefore we need to reduce the backlog of the
child qdisc before calling it. Otherwise it would miss the opportunity
to call cops->qlen_notify(), in the case of DRR, it resulted in UAF
since DRR uses ->qlen_notify() to maintain its active list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: tuner: xc5000: Fix use-after-free in xc5000_release
The original code uses cancel_delayed_work() in xc5000_release(), which
does not guarantee that the delayed work item timer_sleep has fully
completed if it was already running. This leads to use-after-free scenarios
where xc5000_release() may free the xc5000_priv while timer_sleep is still
active and attempts to dereference the xc5000_priv.
A typical race condition is illustrated below:
CPU 0 (release thread) | CPU 1 (delayed work callback)
xc5000_release() | xc5000_do_timer_sleep()
cancel_delayed_work() |
hybrid_tuner_release_state(priv) |
kfree(priv) |
| priv = container_of() // UAF
Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensure
that the timer_sleep is properly canceled before the xc5000_priv memory
is deallocated.
A deadlock concern was considered: xc5000_release() is called in a process
context and is not holding any locks that the timer_sleep work item might
also need. Therefore, the use of the _sync() variant is safe here.
This bug was initially identified through static analysis.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda: fix a possible null-pointer dereference due to data race in snd_hdac_regmap_sync()
The variable codec->regmap is often protected by the lock
codec->regmap_lock when is accessed. However, it is accessed without
holding the lock when is accessed in snd_hdac_regmap_sync():
if (codec->regmap)
In my opinion, this may be a harmful race, because if codec->regmap is
set to NULL right after the condition is checked, a null-pointer
dereference can occur in the called function regcache_sync():
map->lock(map->lock_arg); --> Line 360 in drivers/base/regmap/regcache.c
To fix this possible null-pointer dereference caused by data race, the
mutex_lock coverage is extended to protect the if statement as well as the
function call to regcache_sync().
[ Note: the lack of the regmap_lock itself is harmless for the current
codec driver implementations, as snd_hdac_regmap_sync() is only for
PM runtime resume that is prohibited during the codec probe.
But the change makes the whole code more consistent, so it's merged
as is -- tiwai ]

The direct cause of this issue is that after smc_listen_out_connected(),
newclcsock->sk may be NULL since it will releases the smcsk. Therefore,
if the application closes the socket immediately after accept,
newclcsock->sk can be NULL. A possible execution order could be as
follows:
smc_listen_work | userspace
-----------------------------------------------------------------
lock_sock(sk) |
smc_listen_out_connected() |
| \- smc_listen_out |
| | \- release_sock |
| |- sk->sk_data_ready() |
| fd = accept();
| close(fd);
| \- socket->sk = NULL;
/* newclcsock->sk is NULL now */
SMC_STAT_SERV_SUCC_INC(sock_net(newclcsock->sk))
Since smc_listen_out_connected() will not fail, simply swapping the order
of the code can easily fix this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: tls: handle backlogging of crypto requests
Since we're setting the CRYPTO_TFM_REQ_MAY_BACKLOG flag on our
requests to the crypto API, crypto_aead_{encrypt,decrypt} can return
-EBUSY instead of -EINPROGRESS in valid situations. For example, when
the cryptd queue for AESNI is full (easy to trigger with an
artificially low cryptd.cryptd_max_cpu_qlen), requests will be enqueued
to the backlog but still processed. In that case, the async callback
will also be called twice: first with err == -EINPROGRESS, which it
seems we can just ignore, then with err == 0.
Compared to Sabrina's original patch this version uses the new
tls_*crypt_async_wait() helpers and converts the EBUSY to
EINPROGRESS to avoid having to modify all the error handling
paths. The handling is identical.

Summary
In the Linux kernel, the following vulnerability has been resolved:
jbd2: check 'jh->b_transaction' before removing it from checkpoint
Following process will corrupt ext4 image:
Step 1:
jbd2_journal_commit_transaction
__jbd2_journal_insert_checkpoint(jh, commit_transaction)
// Put jh into trans1->t_checkpoint_list
journal->j_checkpoint_transactions = commit_transaction
// Put trans1 into journal->j_checkpoint_transactions
Step 2:
do_get_write_access
test_clear_buffer_dirty(bh) // clear buffer dirty，set jbd dirty
__jbd2_journal_file_buffer(jh, transaction) // jh belongs to trans2
Step 3:
drop_cache
journal_shrink_one_cp_list
jbd2_journal_try_remove_checkpoint
if (!trylock_buffer(bh)) // lock bh, true
if (buffer_dirty(bh)) // buffer is not dirty
__jbd2_journal_remove_checkpoint(jh)
// remove jh from trans1->t_checkpoint_list
Step 4:
jbd2_log_do_checkpoint
trans1 = journal->j_checkpoint_transactions
// jh is not in trans1->t_checkpoint_list
jbd2_cleanup_journal_tail(journal) // trans1 is done
Step 5: Power cut, trans2 is not committed, jh is lost in next mounting.
Fix it by checking 'jh->b_transaction' before remove it from checkpoint.

The window can be retried indefinitely at no cost, and the unclean shutdown that exposes the loss is routine in the deployment classes most affected (embedded, automotive, IoT, battery devices, cloud instances subject to host failure).\nPR:L - Any unprivileged local user with write access to any ext4/ocfs2 filesystem \u2014 /tmp or their own home directory suffices \u2014 generates the journal commits and reclaim pressure that hit the racy path. No capabilities, mount privileges, or user-namespace tricks are needed.\nUI:N - The attacker\u0027s own filesystem workload plus background commit/reclaim activity is sufficient; no action by any other user is required. The subsequent power loss or crash is an environmental event, not user interaction.\nS:U - The corruption stays within the kernel\u0027s own filesystem stack and the affected block device; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Rolling a metadata block back to a pre-trans1 state resurrects stale inode block pointers and allocation bitmaps, cross-linking blocks that were freed and have since been reallocated to other users\u0027 files, so an unprivileged user can end up reading arbitrary other-tenant file contents. The exposure is unbounded in size rather than a small fixed leak.\nI:H - The bug causes silent, permanent loss of committed filesystem metadata \u2014 inode tables, block/inode bitmaps, extent trees and directory blocks (and file data under data=journal) \u2014 that survives journal replay, which is exactly the \"corrupt ext4 image\" outcome described by the fix author. This is arbitrary, attacker-influenced modification of on-disk state with no integrity protection remaining.\nA:H - The resulting inconsistency triggers `ext4_error()` on the next access, which takes the filesystem read-only under the default errors=remount-ro or panics the machine under errors=panic; a corrupted root filesystem leaves an embedded, automotive, or appliance device unbootable until an offline fsck."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: rose: convert 'use' field to refcount_t
The 'use' field in struct rose_neigh is used as a reference counter but
lacks atomicity. This can lead to race conditions where a rose_neigh
structure is freed while still being referenced by other code paths.
For example, when rose_neigh->use becomes zero during an ioctl operation
via rose_rt_ioctl(), the structure may be removed while its timer is
still active, potentially causing use-after-free issues.
This patch changes the type of 'use' from unsigned short to refcount_t and
updates all code paths to use rose_neigh_hold() and rose_neigh_put() which
operate reference counts atomically.

Summary
In the Linux kernel, the following vulnerability has been resolved:
comedi: Make insn_rw_emulate_bits() do insn->n samples
The `insn_rw_emulate_bits()` function is used as a default handler for
`INSN_READ` instructions for subdevices that have a handler for
`INSN_BITS` but not for `INSN_READ`. Similarly, it is used as a default
handler for `INSN_WRITE` instructions for subdevices that have a handler
for `INSN_BITS` but not for `INSN_WRITE`. It works by emulating the
`INSN_READ` or `INSN_WRITE` instruction handling with a constructed
`INSN_BITS` instruction. However, `INSN_READ` and `INSN_WRITE`
instructions are supposed to be able read or write multiple samples,
indicated by the `insn->n` value, but `insn_rw_emulate_bits()` currently
only handles a single sample. For `INSN_READ`, the comedi core will
copy `insn->n` samples back to user-space. (That triggered KASAN
kernel-infoleak errors when `insn->n` was greater than 1, but that is
being fixed more generally elsewhere in the comedi core.)
Make `insn_rw_emulate_bits()` either handle `insn->n` samples, or return
an error, to conform to the general expectation for `INSN_READ` and
`INSN_WRITE` handlers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: do not allow SET_ID to refer to another table
When doing lookups for sets on the same batch by using its ID, a set from a
different table can be used.
Then, when the table is removed, a reference to the set may be kept after
the set is freed, leading to a potential use-after-free.
When looking for sets by ID, use the table that was used for the lookup by
name, and only return sets belonging to that same table.
This fixes CVE-2022-2586, also reported as ZDI-CAN-17470.

Summary
In the Linux kernel, the following vulnerability has been resolved:
md/raid10: prevent soft lockup while flush writes
Currently, there is no limit for raid1/raid10 plugged bio. While flushing
writes, raid1 has cond_resched() while raid10 doesn't, and too many
writes can cause soft lockup.
Follow up soft lockup can be triggered easily with writeback test for
raid10 with ramdisks:
watchdog: BUG: soft lockup - CPU#10 stuck for 27s! [md0_raid10:1293]

Fix the problem by adding cond_resched() to raid10 like what raid1 did.
Note that unlimited plugged bio still need to be optimized, for example,
in the case of lots of dirty pages writeback, this will take lots of
memory and io will spend a long time in plug, hence io latency is bad.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Take RTNL lock when needed before calling xdp_set_features()
Hold RTNL lock when calling xdp_set_features() with a registered netdev,
as the call triggers the netdev notifiers. This could happen when
switching from uplink rep to nic profile for example.
This resolves the following call trace:

Above issue may happens as follows:
ext4_da_write_begin
ext4_create_inline_data
ext4_clear_inode_flag(inode, EXT4_INODE_EXTENTS);
ext4_set_inode_flag(inode, EXT4_INODE_INLINE_DATA);
__ext4_ioctl
ext4_ext_migrate -> will lead to eh->eh_entries not zero, and set extent flag
ext4_da_write_begin
ext4_da_convert_inline_data_to_extent
ext4_da_write_inline_data_begin
ext4_da_map_blocks
ext4_insert_delayed_block
if (!ext4_es_scan_clu(inode, &ext4_es_is_delonly, lblk))
if (!ext4_es_scan_clu(inode, &ext4_es_is_mapped, lblk))
ext4_clu_mapped(inode, EXT4_B2C(sbi, lblk)); -> will return 1
allocated = true;
ext4_es_insert_delayed_block(inode, lblk, allocated);
ext4_writepages
mpage_map_and_submit_extent(handle, &mpd, &give_up_on_write); -> return -ENOSPC
mpage_release_unused_pages(&mpd, give_up_on_write); -> give_up_on_write == 1
ext4_es_remove_extent
ext4_da_release_space(inode, reserved);
if (unlikely(to_free > ei->i_reserved_data_blocks))
-> to_free == 1 but ei->i_reserved_data_blocks == 0
-> then trigger warning as above
To solve above issue, forbid inode do migrate which has inline data.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/mm/64: define ARCH_PAGE_TABLE_SYNC_MASK and arch_sync_kernel_mappings()
Define ARCH_PAGE_TABLE_SYNC_MASK and arch_sync_kernel_mappings() to ensure
page tables are properly synchronized when calling p*d_populate_kernel().
For 5-level paging, synchronization is performed via
pgd_populate_kernel(). In 4-level paging, pgd_populate() is a no-op, so
synchronization is instead performed at the P4D level via
p4d_populate_kernel().
This fixes intermittent boot failures on systems using 4-level paging and
a large amount of persistent memory:
BUG: unable to handle page fault for address: ffffe70000000034
#PF: supervisor write access in kernel mode
#PF: error_code(0x0002) - not-present page

Summary
In the Linux kernel, the following vulnerability has been resolved:
igb: revert rtnl_lock() that causes deadlock
The commit 6faee3d4ee8b ("igb: Add lock to avoid data race") adds
rtnl_lock to eliminate a false data race shown below
(FREE from device detaching) | (USE from netdev core)
igb_remove | igb_ndo_get_vf_config
igb_disable_sriov | vf >= adapter->vfs_allocated_count?
kfree(adapter->vf_data) |
adapter->vfs_allocated_count = 0 |
| memcpy(... adapter->vf_data[vf]
The above race will never happen and the extra rtnl_lock causes deadlock
below

Since the igb_disable_sriov() will call pci_disable_sriov() before
releasing any resources, the netdev core will synchronize the cleanup to
avoid any races. This patch removes the useless rtnl_(un)lock to guarantee
correctness.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix optc2_configure warning on dcn314
[Why]
dcn314 uses optc2_configure_crc() that wraps
optc1_configure_crc() + set additional registers
not applicable to dcn314.
It's not critical but when used leads to warning like:
WARNING: drivers/gpu/drm/amd/amdgpu/../display/dc/dc_helper.c
Call Trace:
<TASK>
generic_reg_set_ex+0x6d/0xe0 [amdgpu]

amdgpu_dm_crtc_configure_crc_source+0x5d/0xe0 [amdgpu]
[How]
Use optc1_configure_crc() directly

Through the vmcore, I found it's because in tracing_read_pipe(),
ring_buffer_empty_cpu() found some buffer is not empty but then it
cannot read anything due to "rb_num_of_entries() == 0" always true,
Then it infinitely loop the procedure due to user buffer not been
filled, see following code path:
tracing_read_pipe() {
... ...
waitagain:
tracing_wait_pipe() // 1. find non-empty buffer here
trace_find_next_entry_inc() // 2. loop here try to find an entry
__find_next_entry()
ring_buffer_empty_cpu(); // 3. find non-empty buffer
peek_next_entry() // 4. but peek always return NULL
ring_buffer_peek()
rb_buffer_peek()
rb_get_reader_page()
// 5. because rb_num_of_entries() == 0 always true here
// then return NULL
// 6. user buffer not been filled so goto 'waitgain'
// and eventually leads to an deadloop in kernel!!!
}
By some analyzing, I found that when resetting ringbuffer, the 'entries'
of its pages are not all cleared (see rb_reset_cpu()). Then when reducing
the ringbuffer, and if some reduced pages exist dirty 'entries' data, they
will be added into 'cpu_buffer->overrun' (see rb_remove_pages()), which
cause wrong 'overrun' count and eventually cause the deadloop issue.
To fix it, we need to clear every pages in rb_reset_cpu().

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers: base: Free devm resources when unregistering a device
In the current code, devres_release_all() only gets called if the device
has a bus and has been probed.
This leads to issues when using bus-less or driver-less devices where
the device might never get freed if a managed resource holds a reference
to the device. This is happening in the DRM framework for example.
We should thus call devres_release_all() in the device_del() function to
make sure that the device-managed actions are properly executed when the
device is unregistered, even if it has neither a bus nor a driver.
This is effectively the same change than commit 2f8d16a996da ("devres:
release resources on device_del()") that got reverted by commit
a525a3ddeaca ("driver core: free devres in device_release") over
memory leaks concerns.
This patch effectively combines the two commits mentioned above to
release the resources both on device_del() and device_release() and get
the best of both worlds.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbcon: fix integer overflow in fbcon_do_set_font
Fix integer overflow vulnerabilities in fbcon_do_set_font() where font
size calculations could overflow when handling user-controlled font
parameters.
The vulnerabilities occur when:
1. CALC_FONTSZ(h, pitch, charcount) performs h * pith * charcount
multiplication with user-controlled values that can overflow.
2. FONT_EXTRA_WORDS * sizeof(int) + size addition can also overflow
3. This results in smaller allocations than expected, leading to buffer
overflows during font data copying.
Add explicit overflow checking using check_mul_overflow() and
check_add_overflow() kernel helpers to safety validate all size
calculations before allocation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mptcp: fix NULL pointer in can_accept_new_subflow
When testing valkey benchmark tool with MPTCP, the kernel panics in
'mptcp_can_accept_new_subflow' because subflow_req->msk is NULL.
Call trace:
mptcp_can_accept_new_subflow (./net/mptcp/subflow.c:63 (discriminator 4)) (P)
subflow_syn_recv_sock (./net/mptcp/subflow.c:854)
tcp_check_req (./net/ipv4/tcp_minisocks.c:863)
tcp_v4_rcv (./net/ipv4/tcp_ipv4.c:2268)
ip_protocol_deliver_rcu (./net/ipv4/ip_input.c:207)
ip_local_deliver_finish (./net/ipv4/ip_input.c:234)
ip_local_deliver (./net/ipv4/ip_input.c:254)
ip_rcv_finish (./net/ipv4/ip_input.c:449)
...
According to the debug log, the same req received two SYN-ACK in a very
short time, very likely because the client retransmits the syn ack due
to multiple reasons.
Even if the packets are transmitted with a relevant time interval, they
can be processed by the server on different CPUs concurrently). The
'subflow_req->msk' ownership is transferred to the subflow the first,
and there will be a risk of a null pointer dereference here.
This patch fixes this issue by moving the 'subflow_req->msk' under the
`own_req == true` conditional.
Note that the !msk check in subflow_hmac_valid() can be dropped, because
the same check already exists under the own_req mpj branch where the
code has been moved to.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm stats: check for and propagate alloc_percpu failure
Check alloc_precpu()'s return value and return an error from
dm_stats_init() if it fails. Update alloc_dev() to fail if
dm_stats_init() does.
Otherwise, a NULL pointer dereference will occur in dm_stats_cleanup()
even if dm-stats isn't being actively used.

The driver is not bound to any network stack, so exploitation requires local access to the media device.\nAC:L - The condition is simply an HFI message whose header `size` field disagrees with the queue-derived word count, which the message producer fully controls (compromised/misbehaving Venus firmware, the `rd_idx == qsize` wrap edge case, or a shared-memory TOCTOU with the co-processor); no unpredictable memory layout or victim state is required, and the message queue can be pumped repeatedly.\nPR:L - An unprivileged local user needs only access to the venus video device node (video group on Qualcomm Linux boards/Chromebooks, the mediacodec sandbox on Android) to instantiate a session and cause `SESSION_INIT_DONE`/`SYS_INIT_DONE` messages to be parsed; no CAP_SYS_ADMIN or root is involved.\nUI:N - Once a codec session exists, the malformed packet is consumed automatically by `venus_isr_thread()` on the firmware interrupt. No action by any other user is needed.\nS:U - The out-of-bounds access occurs in kernel memory and the impacted component is the same kernel that contains the vulnerable driver; no VM, IOMMU, or sandbox authority boundary is crossed.\nC:H - `hfi_parser()` and `event_seq_changed()` walk up to `hdr-\u003esize` (a full u32, ~4 GB) past the 12 KB `pkt_buf` inside `struct venus_hfi_device`, reading adjacent kernel heap; the harvested bytes are stored into `core-\u003ecaps` (formats, profile/level, capability ranges) and event data that userspace can read back via `VIDIOC_ENUM_FMT`, `QUERY_EXT_CTRL`, and V4L2 events, giving a practical kernel-memory disclosure primitive.\nI:H - The unbounded parse writes attacker-influenced out-of-bounds data into persistent driver state \u2014 codec capability arrays, profile/level tables, and `hfi_buffer_requirements` \u2014 which later drive buffer sizing and control ranges, corrupting kernel state in a way that can cascade into further memory corruption.\nA:H - An oversized `hdr-\u003esize` makes the parser walk far beyond the slab-allocated `venus_hfi_device` into unmapped memory, producing a kernel oops/panic in the interrupt thread; it can be triggered repeatedly by any process able to open the codec device."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: bcd2000: Fix a UAF bug on the error path of probing
When the driver fails in snd_card_register() at probe time, it will free
the 'bcd2k->midi_out_urb' before killing it, which may cause a UAF bug.
The following log can reveal it:
[ 50.727020] BUG: KASAN: use-after-free in bcd2000_input_complete+0x1f1/0x2e0 [snd_bcd2000]
[ 50.727623] Read of size 8 at addr ffff88810fab0e88 by task swapper/4/0
[ 50.729530] Call Trace:
[ 50.732899] bcd2000_input_complete+0x1f1/0x2e0 [snd_bcd2000]
Fix this by adding usb_kill_urb() before usb_free_urb().

Summary
In the Linux kernel, the following vulnerability has been resolved:
xfrm: Duplicate SPI Handling
The issue originates when Strongswan initiates an XFRM_MSG_ALLOCSPI
Netlink message, which triggers the kernel function xfrm_alloc_spi().
This function is expected to ensure uniqueness of the Security Parameter
Index (SPI) for inbound Security Associations (SAs). However, it can
return success even when the requested SPI is already in use, leading
to duplicate SPIs assigned to multiple inbound SAs, differentiated
only by their destination addresses.
This behavior causes inconsistencies during SPI lookups for inbound packets.
Since the lookup may return an arbitrary SA among those with the same SPI,
packet processing can fail, resulting in packet drops.
According to RFC 4301 section 4.4.2 , for inbound processing a unicast SA
is uniquely identified by the SPI and optionally protocol.
Reproducing the Issue Reliably:
To consistently reproduce the problem, restrict the available SPI range in
charon.conf : spi_min = 0x10000000 spi_max = 0x10000002
This limits the system to only 2 usable SPI values.
Next, create more than 2 Child SA. each using unique pair of src/dst address.
As soon as the 3rd Child SA is initiated, it will be assigned a duplicate
SPI, since the SPI pool is already exhausted.
With a narrow SPI range, the issue is consistently reproducible.
With a broader/default range, it becomes rare and unpredictable.
Current implementation:
xfrm_spi_hash() lookup function computes hash using daddr, proto, and family.
So if two SAs have the same SPI but different destination addresses, then
they will:
a. Hash into different buckets
b. Be stored in different linked lists (byspi + h)
c. Not be seen in the same hlist_for_each_entry_rcu() iteration.
As a result, the lookup will result in NULL and kernel allows that Duplicate SPI
Proposed Change:
xfrm_state_lookup_spi_proto() does a truly global search - across all states,
regardless of hash bucket and matches SPI and proto.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSv4.2 fix problems with __nfs42_ssc_open
A destination server while doing a COPY shouldn't accept using the
passed in filehandle if its not a regular filehandle.
If alloc_file_pseudo() has failed, we need to decrement a reference
on the newly created inode, otherwise it leaks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vxlan: Fix NPD in {arp,neigh}_reduce() when using nexthop objects
When the "proxy" option is enabled on a VXLAN device, the device will
suppress ARP requests and IPv6 Neighbor Solicitation messages if it is
able to reply on behalf of the remote host. That is, if a matching and
valid neighbor entry is configured on the VXLAN device whose MAC address
is not behind the "any" remote (0.0.0.0 / ::).
The code currently assumes that the FDB entry for the neighbor's MAC
address points to a valid remote destination, but this is incorrect if
the entry is associated with an FDB nexthop group. This can result in a
NPD [1][3] which can be reproduced using [2][4].
Fix by checking that the remote destination exists before dereferencing
it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ftrace: Fix invalid address access in lookup_rec() when index is 0
KASAN reported follow problem:
BUG: KASAN: use-after-free in lookup_rec
Read of size 8 at addr ffff000199270ff0 by task modprobe
CPU: 2 Comm: modprobe
Call trace:
kasan_report
__asan_load8
lookup_rec
ftrace_location
arch_check_ftrace_location
check_kprobe_address_safe
register_kprobe
When checking pg->records[pg->index - 1].ip in lookup_rec(), it can get a
pg which is newly added to ftrace_pages_start in ftrace_process_locs().
Before the first pg->index++, index is 0 and accessing pg->records[-1].ip
will cause this problem.
Don't check the ip when pg->index is 0.

Summary
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: devicetree: fix null pointer dereferencing in pinctrl_dt_to_map
Here is the BUG report by KASAN about null pointer dereference:
BUG: KASAN: null-ptr-deref in strcmp+0x2e/0x50
Read of size 1 at addr 0000000000000000 by task python3/2640
Call Trace:
strcmp
__of_find_property
of_find_property
pinctrl_dt_to_map
kasprintf() would return NULL pointer when kmalloc() fail to allocate.
So directly return ENOMEM, if kasprintf() return NULL pointer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSv4/pnfs: Fix a use-after-free bug in open
If someone cancels the open RPC call, then we must not try to free
either the open slot or the layoutget operation arguments, since they
are likely still in use by the hung RPC call.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: handle get_client_locked() failure in nfsd4_setclientid_confirm()
Lei Lu recently reported that nfsd4_setclientid_confirm() did not check
the return value from get_client_locked(). a SETCLIENTID_CONFIRM could
race with a confirmed client expiring and fail to get a reference. That
could later lead to a UAF.
Fix this by getting a reference early in the case where there is an
extant confirmed client. If that fails then treat it as if there were no
confirmed client found at all.
In the case where the unconfirmed client is expiring, just fail and
return the result from get_client_locked().

No local access to the server is needed.\nAC:L - The attacker controls its own side of the race and can issue unauthenticated SETCLIENTID_CONFIRM operations at arbitrary rate, and the vulnerable window (force_expire_client() parked in wait_event for cl_rpc_users to drain) stays open as long as the attacker keeps RPCs in flight, so the window is attacker-widened rather than narrow. The forced-expire trigger is an administrative action, but it is the documented response to exactly the kind of misbehaving client the attacker can pose as.\nPR:N - OP_SETCLIENTID_CONFIRM is ALLOWED_WITHOUT_FH/ALLOWED_ON_ABSENT_FS, so no filehandle or export access check is performed, and under the default AUTH_SYS/AUTH_NULL flavors the RPC credentials are self-asserted and never verified. Any host able to reach the NFS port can reach the bug.\nUI:N - The attack is completed entirely by the attacker\u0027s own NFS traffic; no victim opens a file, mounts a filesystem, or otherwise interacts. The concurrent client-expiry is a system/administrative state condition folded into Attack Complexity, not user interaction.\nS:U - The corrupted object (struct nfs4_client) and all consequences remain within the kernel of the NFS server; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed struct nfs4_client is used after free (fsnotify_dentry, nfsd4_probe_callback) and its slab can be re-occupied by attacker-groomed data, giving a path to disclose arbitrary kernel memory. Per kernel scoring guidance a UAF is scored C:H.\nI:H - The UAF yields concrete write primitives on freed memory \u2014 set_bit() on cl_flags, memcpy() into cl_cb_conn, and an unbalanced atomic_dec() in put_client_renew_locked() \u2014 plus a function-pointer dereference via nfsd4_run_cb(\u0026clp-\u003ecl_cb_null), which is exploitable for control-flow hijacking.\nA:H - The use-after-free reliably oopses or panics the NFS server; additionally renew_client_locked() hits WARN_ON(1) (fatal with panic_on_warn) and the cl_rpc_users underflow to -1 leaves force_expire_client() stuck forever in wait_event, producing an unkillable hung task."

Summary
In the Linux kernel, the following vulnerability has been resolved:
FS: JFS: Fix null-ptr-deref Read in txBegin
Syzkaller reported an issue where txBegin may be called
on a superblock in a read-only mounted filesystem which leads
to NULL pointer deref. This could be solved by checking if
the filesystem is read-only before calling txBegin, and returning
with appropiate error code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: don't fail inserts if duplicate has expired
nftables selftests fail:
run-tests.sh testcases/sets/0044interval_overlap_0
Expected: 0-2 . 0-3, got:
W: [FAILED] ./testcases/sets/0044interval_overlap_0: got 1
Insertion must ignore duplicate but expired entries.
Moreover, there is a strange asymmetry in nft_pipapo_activate:
It refetches the current element, whereas the other ->activate callbacks
(bitmap, hash, rhash, rbtree) use elem->priv.
Same for .remove: other set implementations take elem->priv,
nft_pipapo_remove fetches elem->priv, then does a relookup,
remove this.
I suspect this was the reason for the change that prompted the
removal of the expired check in pipapo_get() in the first place,
but skipping exired elements there makes no sense to me, this helper
is used for normal get requests, insertions (duplicate check)
and deactivate callback.
In first two cases expired elements must be skipped.
For ->deactivate(), this gets called for DELSETELEM, so it
seems to me that expired elements should be skipped as well, i.e.
delete request should fail with -ENOENT error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: copy last block omitted in ice_get_module_eeprom()
ice_get_module_eeprom() is broken since commit e9c9692c8a81 ("ice:
Reimplement module reads used by ethtool") In this refactor,
ice_get_module_eeprom() reads the eeprom in blocks of size 8.
But the condition that should protect the buffer overflow
ignores the last block. The last block always contains zeros.
Bug uncovered by ethtool upstream commit 9538f384b535
("netlink: eeprom: Defer page requests to individual parsers")
After this commit, ethtool reads a block with length = 1;
to read the SFF-8024 identifier value.

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: gs_usb: fix time stamp counter initialization
If the gs_usb device driver is unloaded (or unbound) before the
interface is shut down, the USB stack first calls the struct
usb_driver::disconnect and then the struct net_device_ops::ndo_stop
callback.
In gs_usb_disconnect() all pending bulk URBs are killed, i.e. no more
RX'ed CAN frames are send from the USB device to the host. Later in
gs_can_close() a reset control message is send to each CAN channel to
remove the controller from the CAN bus. In this race window the USB
device can still receive CAN frames from the bus and internally queue
them to be send to the host.
At least in the current version of the candlelight firmware, the queue
of received CAN frames is not emptied during the reset command. After
loading (or binding) the gs_usb driver, new URBs are submitted during
the struct net_device_ops::ndo_open callback and the candlelight
firmware starts sending its already queued CAN frames to the host.
However, this scenario was not considered when implementing the
hardware timestamp function. The cycle counter/time counter
infrastructure is set up (gs_usb_timestamp_init()) after the USBs are
submitted, resulting in a NULL pointer dereference if
timecounter_cyc2time() (via the call chain:
gs_usb_receive_bulk_callback() -> gs_usb_set_timestamp() ->
gs_usb_skb_set_timestamp()) is called too early.
Move the gs_usb_timestamp_init() function before the URBs are
submitted to fix this problem.
For a comprehensive solution, we need to consider gs_usb devices with
more than 1 channel. The cycle counter/time counter infrastructure is
setup per channel, but the RX URBs are per device. Once gs_can_open()
of _a_ channel has been called, and URBs have been submitted, the
gs_usb_receive_bulk_callback() can be called for _all_ available
channels, even for channels that are not running, yet. As cycle
counter/time counter has not set up, this will again lead to a NULL
pointer dereference.
Convert the cycle counter/time counter from a "per channel" to a "per
device" functionality. Also set it up, before submitting any URBs to
the device.
Further in gs_usb_receive_bulk_callback(), don't process any URBs for
not started CAN channels, only resubmit the URB.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing/histograms: Add histograms to hist_vars if they have referenced variables
Hist triggers can have referenced variables without having direct
variables fields. This can be the case if referenced variables are added
for trigger actions. In this case the newly added references will not
have field variables. Not taking such referenced variables into
consideration can result in a bug where it would be possible to remove
hist trigger with variables being refenced. This will result in a bug
that is easily reproducable like so
$ cd /sys/kernel/tracing
$ echo 'synthetic_sys_enter char[] comm; long id' >> synthetic_events
$ echo 'hist:keys=common_pid.execname,id.syscall:vals=hitcount:comm=common_pid.execname' >> events/raw_syscalls/sys_enter/trigger
$ echo 'hist:keys=common_pid.execname,id.syscall:onmatch(raw_syscalls.sys_enter).synthetic_sys_enter($comm, id)' >> events/raw_syscalls/sys_enter/trigger
$ echo '!hist:keys=common_pid.execname,id.syscall:vals=hitcount:comm=common_pid.execname' >> events/raw_syscalls/sys_enter/trigger

"value": "AV:L - The vulnerability is reached only by writing hist trigger commands to tracefs files under /sys/kernel/tracing/events/*/trigger, which requires local access to the machine. There is no network or remote-peer path into `event_hist_trigger_parse()`.\nAC:L - The upstream reproducer is four deterministic shell writes with no race window, memory-layout requirement, or timing dependency, and the dangling reference is then dereferenced by the attacker\u0027s own syscalls via `raw_syscalls:sys_enter`. `CONFIG_HIST_TRIGGERS` is enabled in all major distro and Android kernels, so the code is present in practice.\nPR:L - tracefs is not user-namespace mountable, but write access to the tracing hierarchy is routinely delegated to non-root principals in real deployments (Android/Perfetto `traced_probes`, ChromeOS debugd, `gid=`-mounted tracing groups), so a low-privileged account can reach the trigger files. This matches the established scoring for tracefs-gated tracing use-after-frees (CVE-2025-21899, CVE-2025-22035, CVE-2025-38101), all rated PR:L.\nUI:N - The attacker performs every step \u2014 creating both triggers, removing the defining one, and firing the event through their own syscalls. No action by any other user or administrator is needed.\nS:U - The use-after-free is confined to kernel heap objects owned by the tracing subsystem within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a slab use-after-free where `hist_field-\u003evar.hist_data` and the chased `map`/`entry`/`elt` pointers come from reallocatable freed memory, and `tracing_map_read_var()` writes the dereferenced value into a synthetic event the attacker reads back from the trace ring buffer \u2014 an attacker-controllable kernel memory disclosure channel.\nI:H - After reclaiming the freed `hist_trigger_data`, `__tracing_map_insert()` performs `cmpxchg` on `entry-\u003ekey`, `atomic64_inc(\u0026map-\u003ehits)`, and `tracing_map_var_set()` writes `elt-\u003evar_set[var_idx] = true` through attacker-influenced pointers, giving a heap write primitive suitable for further corruption.\nA:H - The bug reproduces as a KASAN slab-use-after-free read in `resolve_var_refs()` and, without KASAN, dereferences a stale pointer chain that readily oopses the kernel. It fires from the extremely hot `sys_enter` tracepoint, so the crash is immediate and repeatable."

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/core: Fix null-ptr-deref in ib_core_cleanup()
KASAN reported a null-ptr-deref error:
KASAN: null-ptr-deref in range [0x0000000000000118-0x000000000000011f]
CPU: 1 PID: 379
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996)
RIP: 0010:destroy_workqueue+0x2f/0x740
RSP: 0018:ffff888016137df8 EFLAGS: 00000202
...
Call Trace:
ib_core_cleanup+0xa/0xa1 [ib_core]
__do_sys_delete_module.constprop.0+0x34f/0x5b0
do_syscall_64+0x3a/0x90
entry_SYSCALL_64_after_hwframe+0x63/0xcd
RIP: 0033:0x7fa1a0d221b7
...
It is because the fail of roce_gid_mgmt_init() is ignored:
ib_core_init()
roce_gid_mgmt_init()
gid_cache_wq = alloc_ordered_workqueue # fail
...
ib_core_cleanup()
roce_gid_mgmt_cleanup()
destroy_workqueue(gid_cache_wq)
# destroy an unallocated wq
Fix this by catching the fail of roce_gid_mgmt_init() in ib_core_init().

Summary
In the Linux kernel, the following vulnerability has been resolved:
platform/chrome: cros_ec_chardev: fix kernel data leak from ioctl
It is possible to peep kernel page's data by providing larger `insize`
in struct cros_ec_command[1] when invoking EC host commands.
Fix it by using zeroed memory.

WHen the ring exits, cleanup is done and the final cancelation and
waiting on completions is done by io_ring_exit_work. That function is
invoked by kworker, which doesn't take any signals. Because of that, it
doesn't really matter if we wait for completions in TASK_INTERRUPTIBLE
or TASK_UNINTERRUPTIBLE state. However, it does matter to the hung task
detection checker!
Normally we expect cancelations and completions to happen rather
quickly. Some test cases, however, will exit the ring and park the
owning task stopped (eg via SIGSTOP). If the owning task needs to run
task_work to complete requests, then io_ring_exit_work won't make any
progress until the task is runnable again. Hence io_ring_exit_work can
trigger the hung task detection, which is particularly problematic if
panic-on-hung-task is enabled.
As the ring exit doesn't take signals to begin with, have it wait
interruptibly rather than uninterruptibly. io_uring has a separate
stuck-exit warning that triggers independently anyway, so we're not
really missing anything by making this switch.

Summary
In the Linux kernel, the following vulnerability has been resolved:
regulator: da9063: better fix null deref with partial DT
Two versions of the original patch were sent but V1 was merged instead
of V2 due to a mistake.
So update to V2.
The advantage of V2 is that it completely avoids dereferencing the pointer,
even just to take the address, which may fix problems with some compilers.
Both versions work on my gcc 9.4 but use the safer one.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/xe/pf: Clear all LMTT pages on alloc
Our LMEM buffer objects are not cleared by default on alloc
and during VF provisioning we only setup LMTT PTEs for the
actually provisioned LMEM range. But beyond that valid range
we might leave some stale data that could either point to some
other VFs allocations or even to the PF pages.
Explicitly clear all new LMTT page to avoid the risk that a
malicious VF would try to exploit that gap.
While around add asserts to catch any undesired PTE overwrites
and low-level debug traces to track LMTT PT life-cycle.
(cherry picked from commit 3fae6918a3e27cce20ded2551f863fb05d4bef8d)

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: kprobe: Fix potential null-ptr-deref on trace_event_file in kprobe_event_gen_test_exit()
When trace_get_event_file() failed, gen_kretprobe_test will be assigned
as the error code. If module kprobe_event_gen_test is removed now, the
null pointer dereference will happen in kprobe_event_gen_test_exit().
Check if gen_kprobe_test or gen_kretprobe_test is error code or NULL
before dereference them.

Summary
In the Linux kernel, the following vulnerability has been resolved:
md/raid5-cache: fix null-ptr-deref for r5l_flush_stripe_to_raid()
r5l_flush_stripe_to_raid() will check if the list 'flushing_ios' is
empty, and then submit 'flush_bio', however, r5l_log_flush_endio()
is clearing the list first and then clear the bio, which will cause
null-ptr-deref:
T1: submit flush io
raid5d
handle_active_stripes
r5l_flush_stripe_to_raid
// list is empty
// add 'io_end_ios' to the list
bio_init
submit_bio
// io1
T2: io1 is done
r5l_log_flush_endio
list_splice_tail_init
// clear the list
T3: submit new flush io
...
r5l_flush_stripe_to_raid
// list is empty
// add 'io_end_ios' to the list
bio_init
bio_uninit
// clear bio->bi_blkg
submit_bio
// null-ptr-deref
Fix this problem by clearing bio before clearing the list in
r5l_log_flush_endio().

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix null pointer dereference in tracing_err_log_open()
Fix an issue in function 'tracing_err_log_open'.
The function doesn't call 'seq_open' if the file is opened only with
write permissions, which results in 'file->private_data' being left as null.
If we then use 'lseek' on that opened file, 'seq_lseek' dereferences
'file->private_data' in 'mutex_lock(&m->lock)', resulting in a kernel panic.
Writing to this node requires root privileges, therefore this bug
has very little security impact.
Tracefs node: /sys/kernel/tracing/error_log
Example Kernel panic:
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000038

No condition outside attacker influence is required.\nPR:L - Gadgetfs endpoint nodes are created with configurable `default_uid`/`default_gid`/`default_perm`, and realistic gadget deployments (Android/embedded USB gadget daemons) expose ep files to unprivileged service uids, matching FunctionFS `uid=`/`gid=`/`fmode=` precedent. No init-namespace root is required once those nodes are openable.\nUI:N - The attacker opens the endpoint file, issues read/write, signals their own wait, and triggers teardown themselves. No separate victim action (mount, confirm, or open) is required beyond an already-active gadget deployment.\nS:U - Stack corruption from `complete()` on the freed on-stack completion stays within the same host kernel security authority. This is standard local kernel memory corruption, not a VM escape, IOMMU bypass, or sandbox boundary cross.\nC:H - `epio_complete()` calling `complete()` on a returned `DECLARE_COMPLETION_ONSTACK` writes into reused kernel stack memory; that stack use-after-free is memory corruption that can be leveraged for kernel information disclosure under CNA guidance.\nI:H - `complete()` performs locked writes (`done++`, waiter wakeups) into whatever reused the stack frame, corrupting kernel stack control/data state and enabling control-flow hijack. Out-of-lifetime stack writes are scored High integrity.\nA:H - Completing into freed stack reliably corrupts stack frames or hits hardening checks, causing kernel oops/panic. The attacker can retrigger the interrupt-and-teardown sequence for sustained denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
octeontx2-pf: Fix SQE threshold checking
Current way of checking available SQE count which is based on
HW updated SQB count could result in driver submitting an SQE
even before CQE for the previously transmitted SQE at the same
index is processed in NAPI resulting losing SKB pointers,
hence a leak. Fix this by checking a consumer index which
is updated once CQE is processed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/active: Fix misuse of non-idle barriers as fence trackers
Users reported oopses on list corruptions when using i915 perf with a
number of concurrently running graphics applications. Root cause analysis
pointed at an issue in barrier processing code -- a race among perf open /
close replacing active barriers with perf requests on kernel context and
concurrent barrier preallocate / acquire operations performed during user
context first pin / last unpin.
When adding a request to a composite tracker, we try to reuse an existing
fence tracker, already allocated and registered with that composite. The
tracker we obtain may already track another fence, may be an idle barrier,
or an active barrier.
If the tracker we get occurs a non-idle barrier then we try to delete that
barrier from a list of barrier tasks it belongs to. However, while doing
that we don't respect return value from a function that performs the
barrier deletion. Should the deletion ever fail, we would end up reusing
the tracker still registered as a barrier task. Since the same structure
field is reused with both fence callback lists and barrier tasks list,
list corruptions would likely occur.
Barriers are now deleted from a barrier tasks list by temporarily removing
the list content, traversing that content with skip over the node to be
deleted, then populating the list back with the modified content. Should
that intentionally racy concurrent deletion attempts be not serialized,
one or more of those may fail because of the list being temporary empty.
Related code that ignores the results of barrier deletion was initially
introduced in v5.4 by commit d8af05ff38ae ("drm/i915: Allow sharing the
idle-barrier from other kernel requests"). However, all users of the
barrier deletion routine were apparently serialized at that time, then the
issue didn't exhibit itself. Results of git bisect with help of a newly
developed igt@gem_barrier_race@remote-request IGT test indicate that list
corruptions might start to appear after commit 311770173fac ("drm/i915/gt:
Schedule request retirement when timeline idles"), introduced in v5.5.
Respect results of barrier deletion attempts -- mark the barrier as idle
only if successfully deleted from the list. Then, before proceeding with
setting our fence as the one currently tracked, make sure that the tracker
we've got is not a non-idle barrier. If that check fails then don't use
that tracker but go back and try to acquire a new, usable one.
v3: use unlikely() to document what outcome we expect (Andi),
- fix bad grammar in commit description.
v2: no code changes,
- blame commit 311770173fac ("drm/i915/gt: Schedule request retirement
when timeline idles"), v5.5, not commit d8af05ff38ae ("drm/i915: Allow
sharing the idle-barrier from other kernel requests"), v5.4,
- reword commit description.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/packet: fix a race in packet_set_ring() and packet_notifier()
When packet_set_ring() releases po->bind_lock, another thread can
run packet_notifier() and process an NETDEV_UP event.
This race and the fix are both similar to that of commit 15fe076edea7
("net/packet: fix a race in packet_bind() and packet_notifier()").
There too the packet_notifier NETDEV_UP event managed to run while a
po->bind_lock critical section had to be temporarily released. And
the fix was similarly to temporarily set po->num to zero to keep
the socket unhooked until the lock is retaken.
The po->bind_lock in packet_set_ring and packet_notifier precede the
introduction of git history.

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: 8250: fix panic due to PSLVERR
When the PSLVERR_RESP_EN parameter is set to 1, the device generates
an error response if an attempt is made to read an empty RBR (Receive
Buffer Register) while the FIFO is enabled.
In serial8250_do_startup(), calling serial_port_out(port, UART_LCR,
UART_LCR_WLEN8) triggers dw8250_check_lcr(), which invokes
dw8250_force_idle() and serial8250_clear_and_reinit_fifos(). The latter
function enables the FIFO via serial_out(p, UART_FCR, p->fcr).
Execution proceeds to the serial_port_in(port, UART_RX).
This satisfies the PSLVERR trigger condition.
When another CPU (e.g., using printk()) is accessing the UART (UART
is busy), the current CPU fails the check (value & ~UART_LCR_SPAR) ==
(lcr & ~UART_LCR_SPAR) in dw8250_check_lcr(), causing it to enter
dw8250_force_idle().
Put serial_port_out(port, UART_LCR, UART_LCR_WLEN8) under the port->lock
to fix this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/ttm: fix CCS handling
Crucible + recent Mesa seems to sometimes hit:
GEM_BUG_ON(num_ccs_blks > NUM_CCS_BLKS_PER_XFER)
And it looks like we can also trigger this with gem_lmem_swapping, if we
modify the test to use slightly larger object sizes.
Looking closer it looks like we have the following issues in
migrate_copy():
- We are using plain integer in various places, which we can easily
overflow with a large object.
- We pass the entire object size (when the src is lmem) into
emit_pte() and then try to copy it, which doesn't work, since we
only have a few fixed sized windows in which to map the pages and
perform the copy. With an object > 8M we therefore aren't properly
copying the pages. And then with an object > 64M we trigger the
GEM_BUG_ON(num_ccs_blks > NUM_CCS_BLKS_PER_XFER).
So it looks like our copy handling for any object > 8M (which is our
CHUNK_SZ) is currently broken on DG2.
Testcase: igt@gem_lmem_swapping
(cherry picked from commit 8676145eb2f53a9940ff70910caf0125bd8a4bc2)

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: debug: Fix potential buffer overflow by snprintf()
snprintf() returns the would-be-filled size when the string overflows
the given buffer size, hence using this value may result in the buffer
overflow (although it's unrealistic).
This patch replaces with a safer version, scnprintf() for papering
over such a potential issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm ioctl: fix misbehavior if list_versions races with module loading
__list_versions will first estimate the required space using the
"dm_target_iterate(list_version_get_needed, &needed)" call and then will
fill the space using the "dm_target_iterate(list_version_get_info,
&iter_info)" call. Each of these calls locks the targets using the
"down_read(&_lock)" and "up_read(&_lock)" calls, however between the first
and second "dm_target_iterate" there is no lock held and the target
modules can be loaded at this point, so the second "dm_target_iterate"
call may need more space than what was the first "dm_target_iterate"
returned.
The code tries to handle this overflow (see the beginning of
list_version_get_info), however this handling is incorrect.
The code sets "param->data_size = param->data_start + needed" and
"iter_info.end = (char *)vers+len" - "needed" is the size returned by the
first dm_target_iterate call; "len" is the size of the buffer allocated by
userspace.
"len" may be greater than "needed"; in this case, the code will write up
to "len" bytes into the buffer, however param->data_size is set to
"needed", so it may write data past the param->data_size value. The ioctl
interface copies only up to param->data_size into userspace, thus part of
the result will be truncated.
Fix this bug by setting "iter_info.end = (char *)vers + needed;" - this
guarantees that the second "dm_target_iterate" call will write only up to
the "needed" buffer and it will exit with "DM_BUFFER_FULL_FLAG" if it
overflows the "needed" space - in this case, userspace will allocate a
larger buffer and retry.
Note that there is also a bug in list_version_get_needed - we need to add
"strlen(tt->name) + 1" to the needed size, not "strlen(tt->name)".

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: rfkill: gpio: Fix crash due to dereferencering uninitialized pointer
Since commit 7d5e9737efda ("net: rfkill: gpio: get the name and type from
device property") rfkill_find_type() gets called with the possibly
uninitialized "const char *type_name;" local variable.
On x86 systems when rfkill-gpio binds to a "BCM4752" or "LNV4752"
acpi_device, the rfkill->type is set based on the ACPI acpi_device_id:
rfkill->type = (unsigned)id->driver_data;
and there is no "type" property so device_property_read_string() will fail
and leave type_name uninitialized, leading to a potential crash.
rfkill_find_type() does accept a NULL pointer, fix the potential crash
by initializing type_name to NULL.
Note likely sofar this has not been caught because:
1. Not many x86 machines actually have a "BCM4752"/"LNV4752" acpi_device
2. The stack happened to contain NULL where type_name is stored

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: fix NULL access of tx->in_use in ice_ll_ts_intr
Recent versions of the E810 firmware have support for an extra interrupt to
handle report of the "low latency" Tx timestamps coming from the
specialized low latency firmware interface. Instead of polling the
registers, software can wait until the low latency interrupt is fired.
This logic makes use of the Tx timestamp tracking structure, ice_ptp_tx, as
it uses the same "ready" bitmap to track which Tx timestamps complete.
Unfortunately, the ice_ll_ts_intr() function does not check if the
tracker is initialized before its first access. This results in NULL
dereference or use-after-free bugs similar to the issues fixed in the
ice_ptp_ts_irq() function.
Fix this by only checking the in_use bitmap (and other fields) if the
tracker is marked as initialized. The reset flow will clear the init field
under lock before it tears the tracker down, thus preventing any
use-after-free or NULL access.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: fix use-after-free bug in refresh_cache_worker()
The UAF bug occurred because we were putting DFS root sessions in
cifs_umount() while DFS cache refresher was being executed.
Make DFS root sessions have same lifetime as DFS tcons so we can avoid
the use-after-free bug is DFS cache refresher and other places that
require IPCs to get new DFS referrals on. Also, get rid of mount
group handling in DFS cache as we no longer need it.
This fixes below use-after-free bug catched by KASAN

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check correct bounds for stream encoder instances for DCN303
[Why & How]
eng_id for DCN303 cannot be more than 1, since we have only two
instances of stream encoders.
Check the correct boundary condition for engine ID for DCN303 prevent
the potential out of bounds access.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: fix double free on tx path.
We see kernel crashes and lockups and KASAN errors related to ax210
firmware crashes. One of the KASAN dumps pointed at the tx path,
and it appears there is indeed a way to double-free an skb.
If iwl_mvm_tx_skb_sta returns non-zero, then the 'skb' sent into the
method will be freed. But, in case where we build TSO skb buffer,
the skb may also be freed in error case. So, return 0 in that particular
error case and do cleanup manually.

A local process sending large GSO TCP traffic over an Intel iwlwifi interface is sufficient.\nAC:L - An attacker can reliably create GSO/TSO skbs by sending large TCP payloads over WiFi (TSO is advertised by default on affected devices), and iwl_mvm_tx_mpdu failure after segmentation is reachable via attacker-influenced conditions such as GFP_ATOMIC tx-cmd allocation failure under memory pressure or STATUS_FW_ERROR; no uncontrolled race is required.\nPR:L - Any unprivileged local user can trigger the path with a normal TCP sendto on the WiFi interface, as shown in the KASAN stack; no root or special capabilities are required.\nUI:N - The attacker triggers the bug by sending their own traffic; no separate victim action is required.\nS:U - This is kernel heap memory corruption within the host kernel\u0027s authority and does not cross a VM, IOMMU, or other security boundary.\nC:H - The bug is a double-free/UAF of an skbuff_fclone_cache object, which per CVSS kernel guidance enables heap reuse and arbitrary read primitives.\nI:H - Double-free of an skb enables heap spraying and corruption suitable for arbitrary write or control-flow hijacking, so integrity impact is High.\nA:H - The double-free produces kernel UAF crashes, oopses, and lockups as reported (KASAN use-after-free and observed crashes), so availability impact is High."

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: af_alg - Set merge to zero early in af_alg_sendmsg
If an error causes af_alg_sendmsg to abort, ctx->merge may contain
a garbage value from the previous loop. This may then trigger a
crash on the next entry into af_alg_sendmsg when it attempts to do
a merge that can't be done.
Fix this by setting ctx->merge to zero near the start of the loop.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sched: Fix sched_numa_find_nth_cpu() if mask offline
sched_numa_find_nth_cpu() uses a bsearch to look for the 'closest'
CPU in sched_domains_numa_masks and given cpus mask. However they
might not intersect if all CPUs in the cpus mask are offline. bsearch
will return NULL in that case, bail out instead of dereferencing a
bogus pointer.
The previous behaviour lead to this bug when using maxcpus=4 on an
rk3399 (LLLLbb) (i.e. booting with all big CPUs offline):

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null pointer check in mod_hdcp_hdcp1_create_session()
The function mod_hdcp_hdcp1_create_session() calls the function
get_first_active_display(), but does not check its return value.
The return value is a null pointer if the display list is empty.
This will lead to a null pointer dereference.
Add a null pointer check for get_first_active_display() and return
MOD_HDCP_STATUS_DISPLAY_NOT_FOUND if the function return null.
This is similar to the commit c3e9826a2202
("drm/amd/display: Add null pointer check for get_first_active_display()").
(cherry picked from commit 5e43eb3cd731649c4f8b9134f857be62a416c893)

There is no network-facing consumer of fs/hfsplus/unicode.c.\nAC:L - The overread length is the raw 16-bit `hfsplus_unistr.length` field the attacker writes into the Catalog/Attributes b-tree node, so a single purpose-built image triggers it deterministically on the first `readdir`, with no race, timing window, or memory-layout precondition outside the attacker\u0027s control. Adjacent kmalloc-2k contents can be groomed by repeated allocations before the directory read.\nPR:L - hfsplus is FS_REQUIRES_DEV without FS_USERNS_MOUNT, so a bare mount(2) needs CAP_SYS_ADMIN, but in the most severe reasonable deployment an unprivileged local user routinely gets a crafted HFS+ image mounted through udisks2 loop-setup, desktop/kiosk removable-media automounters, or `user`/autofs fstab delegation. Once mounted, the getdents64 or listxattr that fires the overread requires no privilege at all.\nUI:N - The attacker performs every step personally \u2014 presents the crafted volume, which an automounter consumes with no human action, and then runs the directory read itself. No second victim user has to be induced into any action.\nS:U - The out-of-bounds access occurs in HFS+ unicode conversion inside the kernel and its effects remain within that same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The loop stops only when the 1530-byte output buffer fills, so it reads up to ~3 KB past the 1036-byte `hfs_find_init()` key allocation \u2014 through the object tail and into neighbouring kmalloc-2k objects \u2014 and every harvested byte is handed to `dir_emit()`/`copy_name()` and returned to userspace as a filename or xattr name. That is a repeatable, attacker-length-controlled kernel heap disclosure primitive suitable for defeating KASLR and lifting secrets from groomed adjacent slab objects.\nI:N - The defect is strictly a read overrun; every store through `op` remains bounded by the remaining output length enforced by `nls-\u003euni2char`, and the `-EINVAL` fallback stays inside the `+1` slack of `strbuf`. No kernel memory is modified.\nA:H - The multi-kilobyte overread can walk off the end of the slab page into unmapped memory, faulting in the middle of `iterate_dir()` while the btree mutex and inode lock are held, which oopses and wedges the filesystem; under KASAN, SLUB_DEBUG, or debug_pagealloc \u2014 common in hardened, appliance, and embedded builds \u2014 it faults immediately, and with panic_on_oops it is a full system panic the attacker can repeat at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ppp: fix memory leak in pad_compress_skb
If alloc_skb() fails in pad_compress_skb(), it returns NULL without
releasing the old skb. The caller does:
skb = pad_compress_skb(ppp, skb);
if (!skb)
goto drop;
drop:
kfree_skb(skb);
When pad_compress_skb() returns NULL, the reference to the old skb is
lost and kfree_skb(skb) ends up doing nothing, leading to a memory leak.
Align pad_compress_skb() semantics with realloc(): only free the old
skb if allocation and compression succeed. At the call site, use the
new_skb variable so the original skb is not lost when pad_compress_skb()
fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
pcmcia: Add error handling for add_interval() in do_validate_mem()
In the do_validate_mem(), the call to add_interval() does not
handle errors. If kmalloc() fails in add_interval(), it could
result in a null pointer being inserted into the linked list,
leading to illegal memory access when sub_interval() is called
next.
This patch adds an error handling for the add_interval(). If
add_interval() returns an error, the function will return early
with the error code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: use timestamp to check for set element timeout
Add a timestamp field at the beginning of the transaction, store it
in the nftables per-netns area.
Update set backend .insert, .deactivate and sync gc path to use the
timestamp, this avoids that an element expires while control plane
transaction is still unfinished.
.lookup and .update, which are used from packet path, still use the
current time to check if the element has expired. And .get path and dump
also since this runs lockless under rcu read size lock. Then, there is
async gc which also needs to check the current time since it runs
asynchronously from a workqueue.

Per kernel scoring guidance, netfilter/nftables netlink control-plane bugs are Local.\nAC:L - The attacker controls both sides of the timing window: `NFTA_SET_ELEM_TIMEOUT`/`NFTA_SET_ELEM_EXPIRATION` set the expiry instant at millisecond granularity, and the length of the netlink batch determines how long the transaction runs under `commit_mutex`, so the element can be made to flip to expired at a chosen point mid-transaction with no reliance on uncontrolled conditions.\nPR:L - `nfnetlink` only requires `netlink_net_capable(skb, CAP_NET_ADMIN)`, which is `ns_capable` against the user namespace owning the netns, so an unprivileged user obtains it with `unshare -Urn`. No real root in the init namespace is needed.\nUI:N - The attacker performs every step from their own process \u2014 create the set, add the timed element, submit the batch \u2014 with no victim action of any kind.\nS:U - The corruption is of kernel heap objects and results in privilege escalation within the same kernel security authority; no VM, IOMMU, or hypervisor boundary is crossed.\nC:H - The double-free/use-after-free on `nft_rhash_elem`/`nft_rbtree_elem`/`nft_pipapo_elem` lets the attacker reclaim the freed slab chunk with a chosen object and read it back via `NFT_MSG_GETSETELEM` dumps and element counter/quota expressions, yielding an arbitrary kernel-memory read primitive; the `use`-counter underflow additionally exposes freed `nft_chain`/`nft_object` contents.\nI:H - The abort path writes into the freed element (`nft_setelem_data_activate()` + `ops-\u003eactivate()` incrementing refcounts through a dangling pointer) and the duplicate-key/double-free conditions give a controllable heap write primitive suitable for control-flow hijacking and root privilege escalation; the dangling-interval side effect also silently alters firewall verdicts.\nA:H - Even without successful exploitation, the double free and the `nft_use_dec` refcount underflow reliably trigger kernel oops/panic (slab corruption, `refcount_t` warnings, freeing a chain still referenced by the packet path), crashing the system."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/mdp5: Don't leak some plane state
Apparently no one noticed that mdp5 plane states leak like a sieve
ever since we introduced plane_state->commit refcount a few years ago
in 21a01abbe32a ("drm/atomic: Fix freeing connector/plane state too
early by tracking commits, v3.")
Fix it by using the right helpers.

There is no remote or adjacent-network path into openvswitch flow-action validation.\nAC:L - Triggering requires only a single well-formed netlink message containing an OVS_ACTION_ATTR_SET whose inner nlattr declares nla_len of 1-3; there is no race, no timing window, and no dependence on memory layout the attacker cannot influence. The negative-length path is fully in-bounds and deterministic, and the actions are validated before the datapath lookup so not even a datapath must exist.\nPR:L - The OVS flow genl ops use GENL_UNS_ADMIN_PERM with .netnsok = true, so the CAP_NET_ADMIN check is scoped to the netns\u0027s owning user namespace and any unprivileged user can satisfy it with `unshare -Urn`. The openvswitch module is autoloaded from an unprivileged CTRL_CMD_GETFAMILY lookup via MODULE_ALIAS_GENL_FAMILY.\nUI:N - The attacker performs the entire sequence themselves via socket()/sendmsg(); no action by any other user or administrator is needed.\nS:U - The corruption is confined to kernel memory under the same security authority as the attacking process; no VM, IOMMU, or hypervisor boundary is crossed.\nC:H - The bug produces out-of-bounds reads beyond the netlink skb \u2014 the KMSAN-confirmed header read, the unbounded forward scan in validate_masked() with a negative length, and a memcpy whose source is read for up to SIZE_MAX bytes. Data copied out of bounds lands in the flow\u0027s actions buffer, which is echoed back to userspace by OVS_FLOW_CMD_GET/DUMP, giving an arbitrary kernel-memory disclosure primitive.\nI:H - With key_len underflowing to (size_t)-1, `memcpy(nla_data(at), nla_data(ovs_key), key_len)` and the following `memset(..., 0xff, key_len)` perform an effectively unbounded out-of-bounds write over the kernel heap using attacker-influenced data. An out-of-bounds write of this scope is a full integrity compromise.\nA:H - The wild memcpy/memset will fault as soon as it walks off mapped memory, and the negative-length validate_masked() loop scans up to 4G of memory; either way the result is a kernel panic, and on sanitizer builds it is an immediate KASAN/KMSAN report. The crash is reachable repeatedly by an unprivileged local user."

Summary
In the Linux kernel, the following vulnerability has been resolved:
sched/core: Do not requeue task on CPU excluded from cpus_mask
The following warning was triggered on a large machine early in boot on
a distribution kernel but the same problem should also affect mainline.
WARNING: CPU: 439 PID: 10 at ../kernel/workqueue.c:2231 process_one_work+0x4d/0x440
Call Trace:
<TASK>
rescuer_thread+0x1f6/0x360
kthread+0x156/0x180
ret_from_fork+0x22/0x30
</TASK>
Commit c6e7bd7afaeb ("sched/core: Optimize ttwu() spinning on p->on_cpu")
optimises ttwu by queueing a task that is descheduling on the wakelist,
but does not check if the task descheduling is still allowed to run on that CPU.
In this warning, the problematic task is a workqueue rescue thread which
checks if the rescue is for a per-cpu workqueue and running on the wrong CPU.
While this is early in boot and it should be possible to create workers,
the rescue thread may still used if the MAYDAY_INITIAL_TIMEOUT is reached
or MAYDAY_INTERVAL and on a sufficiently large machine, the rescue
thread is being used frequently.
Tracing confirmed that the task should have migrated properly using the
stopper thread to handle the migration. However, a parallel wakeup from udev
running on another CPU that does not share CPU cache observes p->on_cpu and
uses task_cpu(p), queues the task on the old CPU and triggers the warning.
Check that the wakee task that is descheduling is still allowed to run
on its current CPU and if not, wait for the descheduling to complete
and select an allowed CPU.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: Fix double free in idxd_setup_wqs()
The clean up in idxd_setup_wqs() has had a couple bugs because the error
handling is a bit subtle. It's simpler to just re-write it in a cleaner
way. The issues here are:
1) If "idxd->max_wqs" is <= 0 then we call put_device(conf_dev) when
"conf_dev" hasn't been initialized.
2) If kzalloc_node() fails then again "conf_dev" is invalid. It's
either uninitialized or it points to the "conf_dev" from the
previous iteration so it leads to a double free.
It's better to free partial loop iterations within the loop and then
the unwinding at the end can handle whole loop iterations. I also
renamed the labels to describe what the goto does and not where the goto
was located.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/ttm: don't leak the ccs state
The kernel only manages the ccs state with lmem-only objects, however
the kernel should still take care not to leak the CCS state from the
previous user.
(cherry picked from commit 353819d85f87be46aeb9c1dd929d445a006fc6ec)

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/siw: Fix the sendmsg byte count in siw_tcp_sendpages
Ever since commit c2ff29e99a76 ("siw: Inline do_tcp_sendpages()"),
we have been doing this:
static int siw_tcp_sendpages(struct socket *s, struct page **page, int offset,
size_t size)
[...]
/* Calculate the number of bytes we need to push, for this page
* specifically */
size_t bytes = min_t(size_t, PAGE_SIZE - offset, size);
/* If we can't splice it, then copy it in, as normal */
if (!sendpage_ok(page[i]))
msg.msg_flags &= ~MSG_SPLICE_PAGES;
/* Set the bvec pointing to the page, with len $bytes */
bvec_set_page(&bvec, page[i], bytes, offset);
/* Set the iter to $size, aka the size of the whole sendpages (!!!) */
iov_iter_bvec(&msg.msg_iter, ITER_SOURCE, &bvec, 1, size);
try_page_again:
lock_sock(sk);
/* Sendmsg with $size size (!!!) */
rv = tcp_sendmsg_locked(sk, &msg, size);
This means we've been sending oversized iov_iters and tcp_sendmsg calls
for a while. This has a been a benign bug because sendpage_ok() always
returned true. With the recent slab allocator changes being slowly
introduced into next (that disallow sendpage on large kmalloc
allocations), we have recently hit out-of-bounds crashes, due to slight
differences in iov_iter behavior between the MSG_SPLICE_PAGES and
"regular" copy paths:
(MSG_SPLICE_PAGES)
skb_splice_from_iter
iov_iter_extract_pages
iov_iter_extract_bvec_pages
uses i->nr_segs to correctly stop in its tracks before OoB'ing everywhere
skb_splice_from_iter gets a "short" read
(!MSG_SPLICE_PAGES)
skb_copy_to_page_nocache copy=iov_iter_count
[...]
copy_from_iter
/* this doesn't help */
if (unlikely(iter->count < len))
len = iter->count;
iterate_bvec
... and we run off the bvecs
Fix this by properly setting the iov_iter's byte count, plus sending the
correct byte count to tcp_sendmsg_locked.

Summary
In the Linux kernel, the following vulnerability has been resolved:
soc: qcom: qmi_encdec: Restrict string length in decode
The QMI TLV value for strings in a lot of qmi element info structures
account for null terminated strings with MAX_LEN + 1. If a string is
actually MAX_LEN + 1 length, this will cause an out of bounds access
when the NULL character is appended in decoding.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/slub: avoid accessing metadata when pointer is invalid in object_err()
object_err() reports details of an object for further debugging, such as
the freelist pointer, redzone, etc. However, if the pointer is invalid,
attempting to access object metadata can lead to a crash since it does
not point to a valid object.
One known path to the crash is when alloc_consistency_checks()
determines the pointer to the allocated object is invalid because of a
freelist corruption, and calls object_err() to report it. The debug code
should report and handle the corruption gracefully and not crash in the
process.
In case the pointer is NULL or check_valid_pointer() returns false for
the pointer, only print the pointer value and skip accessing metadata.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: s390: Fix use-after-free of PCI resources with per-function hotplug
On s390 PCI functions may be hotplugged individually even when they
belong to a multi-function device. In particular on an SR-IOV device VFs
may be removed and later re-added.
In commit a50297cf8235 ("s390/pci: separate zbus creation from
scanning") it was missed however that struct pci_bus and struct
zpci_bus's resource list retained a reference to the PCI functions MMIO
resources even though those resources are released and freed on
hot-unplug. These stale resources may subsequently be claimed when the
PCI function re-appears resulting in use-after-free.
One idea of fixing this use-after-free in s390 specific code that was
investigated was to simply keep resources around from the moment a PCI
function first appeared until the whole virtual PCI bus created for
a multi-function device disappears. The problem with this however is
that due to the requirement of artificial MMIO addreesses (address
cookies) extra logic is then needed to keep the address cookies
compatible on re-plug. At the same time the MMIO resources semantically
belong to the PCI function so tying their lifecycle to the function
seems more logical.
Instead a simpler approach is to remove the resources of an individually
hot-unplugged PCI function from the PCI bus's resource list while
keeping the resources of other PCI functions on the PCI bus untouched.
This is done by introducing pci_bus_remove_resource() to remove an
individual resource. Similarly the resource also needs to be removed
from the struct zpci_bus's resource list. It turns out however, that
there is really no need to add the MMIO resources to the struct
zpci_bus's resource list at all and instead we can simply use the
zpci_bar_struct's resource pointer directly.

In particular on an SR-IOV device VFs\nmay be removed and later re-added.\n\nIn commit a50297cf8235 (\"s390/pci: separate zbus creation from\nscanning\") it was missed however that struct pci_bus and struct\nzpci_bus\u0027s resource list retained a reference to the PCI functions MMIO\nresources even though those resources are released and freed on\nhot-unplug. These stale resources may subsequently be claimed when the\nPCI function re-appears resulting in use-after-free.\n\nOne idea of fixing this use-after-free in s390 specific code that was\ninvestigated was to simply keep resources around from the moment a PCI\nfunction first appeared until the whole virtual PCI bus created for\na multi-function device disappears. The problem with this however is\nthat due to the requirement of artificial MMIO addreesses (address\ncookies) extra logic is then needed to keep the address cookies\ncompatible on re-plug. At the same time the MMIO resources semantically\nbelong to the PCI function so tying their lifecycle to the function\nseems more logical.\n\nInstead a simpler approach is to remove the resources of an individually\nhot-unplugged PCI function from the PCI bus\u0027s resource list while\nkeeping the resources of other PCI functions on the PCI bus untouched.\n\nThis is done by introducing pci_bus_remove_resource() to remove an\nindividual resource. Similarly the resource also needs to be removed\nfrom the struct zpci_bus\u0027s resource list. It turns out however, that\nthere is really no need to add the MMIO resources to the struct\nzpci_bus\u0027s resource list at all and instead we can simply use the\nzpci_bar_struct\u0027s resource pointer directly."

Summary
In the Linux kernel, the following vulnerability has been resolved:
sched/fair: Don't balance task to its current running CPU
We've run into the case that the balancer tries to balance a migration
disabled task and trigger the warning in set_task_cpu() like below:

---[ end trace 0000000000000000 ]---
Further investigation shows that the warning is superfluous, the migration
disabled task is just going to be migrated to its current running CPU.
This is because that on load balance if the dst_cpu is not allowed by the
task, we'll re-select a new_dst_cpu as a candidate. If no task can be
balanced to dst_cpu we'll try to balance the task to the new_dst_cpu
instead. In this case when the migration disabled task is not on CPU it
only allows to run on its current CPU, load balance will select its
current CPU as new_dst_cpu and later triggers the warning above.
The new_dst_cpu is chosen from the env->dst_grpmask. Currently it
contains CPUs in sched_group_span() and if we have overlapped groups it's
possible to run into this case. This patch makes env->dst_grpmask of
group_balance_mask() which exclude any CPUs from the busiest group and
solve the issue. For balancing in a domain with no overlapped groups
the behaviour keeps same as before.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i2c: piix4: Fix adapter not be removed in piix4_remove()
In piix4_probe(), the piix4 adapter will be registered in:
piix4_probe()
piix4_add_adapters_sb800() / piix4_add_adapter()
i2c_add_adapter()
Based on the probed device type, piix4_add_adapters_sb800() or single
piix4_add_adapter() will be called.
For the former case, piix4_adapter_count is set as the number of adapters,
while for antoher case it is not set and kept default *zero*.
When piix4 is removed, piix4_remove() removes the adapters added in
piix4_probe(), basing on the piix4_adapter_count value.
Because the count is zero for the single adapter case, the adapter won't
be removed and makes the sources allocated for adapter leaked, such as
the i2c client and device.
These sources can still be accessed by i2c or bus and cause problems.
An easily reproduced case is that if a new adapter is registered, i2c
will get the leaked adapter and try to call smbus_algorithm, which was
already freed:

single adapter so it can be normally removed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: ucsi: Fix NULL pointer deref in ucsi_connector_change()
When ucsi_init() fails, ucsi->connector is NULL, yet in case of
ucsi_acpi we may still get events which cause the ucs_acpi code to call
ucsi_connector_change(), which then derefs the NULL ucsi->connector
pointer.
Fix this by not setting ucsi->ntfy inside ucsi_init() until ucsi_init()
has succeeded, so that ucsi_connector_change() ignores the events
because UCSI_ENABLE_NTFY_CONNECTOR_CHANGE is not set in the ntfy mask.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_set_pipapo: do not free live element
Pablo reports a crash with large batches of elements with a
back-to-back add/remove pattern. Quoting Pablo:
add_elem("00000000") timeout 100 ms
...
add_elem("0000000X") timeout 100 ms
del_elem("0000000X") <---------------- delete one that was just added
...
add_elem("00005000") timeout 100 ms
1) nft_pipapo_remove() removes element 0000000X
Then, KASAN shows a splat.
Looking at the remove function there is a chance that we will drop a
rule that maps to a non-deactivated element.
Removal happens in two steps, first we do a lookup for key k and return the
to-be-removed element and mark it as inactive in the next generation.
Then, in a second step, the element gets removed from the set/map.
The _remove function does not work correctly if we have more than one
element that share the same key.
This can happen if we insert an element into a set when the set already
holds an element with same key, but the element mapping to the existing
key has timed out or is not active in the next generation.
In such case its possible that removal will unmap the wrong element.
If this happens, we will leak the non-deactivated element, it becomes
unreachable.
The element that got deactivated (and will be freed later) will
remain reachable in the set data structure, this can result in
a crash when such an element is retrieved during lookup (stale
pointer).
Add a check that the fully matching key does in fact map to the element
that we have marked as inactive in the deactivation step.
If not, we need to continue searching.
Add a bug/warn trap at the end of the function as well, the remove
function must not ever be called with an invisible/unreachable/non-existent
element.

The same namespace also lets the attacker send the packets that dereference the freed element, making the whole chain self-contained for an ordinary local user.\nUI:N - The attacker performs every step \u2014 creating the set, driving the add/delete batch, and generating the traffic that hits the stale mapping entry.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mtd: parsers: ofpart: Fix refcount leak in bcm4908_partitions_fw_offset
of_find_node_by_path() returns a node pointer with refcount incremented,
we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: usb: lan78xx: Limit packet length to skb->len
Packet length retrieved from descriptor may be larger than
the actual socket buffer length. In such case the cloned
skb passed up the network stack will leak kernel memory contents.
Additionally prevent integer underflow when size is less than
ETH_FCS_LEN.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ata: libata-transport: fix error handling in ata_tport_add()
In ata_tport_add(), the return value of transport_add_device() is
not checked. As a result, it causes null-ptr-deref while removing
the module, because transport_remove_device() is called to remove
the device that was not added.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: don't check PageError in __extent_writepage
__extent_writepage currenly sets PageError whenever any error happens,
and the also checks for PageError to decide if to call error handling.
This leads to very unclear responsibility for cleaning up on errors.
In the VM and generic writeback helpers the basic idea is that once
I/O is fired off all error handling responsibility is delegated to the
end I/O handler. But if that end I/O handler sets the PageError bit,
and the submitter checks it, the bit could in some cases leak into the
submission context for fast enough I/O.
Fix this by simply not checking PageError and just using the local
ret variable to check for submission errors. This also fundamentally
solves the long problem documented in a comment in __extent_writepage
by never leaking the error bit into the submission context.

Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: cadence-quadspi: Implement refcount to handle unbind during busy
driver support indirect read and indirect write operation with
assumption no force device removal(unbind) operation. However
force device removal(removal) is still available to root superuser.
Unbinding driver during operation causes kernel crash. This changes
ensure driver able to handle such operation for indirect read and
indirect write by implementing refcount to track attached devices
to the controller and gracefully wait and until attached devices
remove operation completed before proceed with removal operation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: avoid resizing to a partial cluster size
This patch avoids an attempt to resize the filesystem to an
unaligned cluster boundary. An online resize to a size that is not
integral to cluster size results in the last iteration attempting to
grow the fs by a negative amount, which trips a BUG_ON and leaves the fs
with a corrupted in-memory superblock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/arm-smmu-qcom: Add SM6115 MDSS compatible
Add the SM6115 MDSS compatible to clients compatible list, as it also
needs that workaround.
Without this workaround, for example, QRB4210 RB2 which is based on
SM4250/SM6115 generates a lot of smmu unhandled context faults during
boot:
arm_smmu_context_fault: 116854 callbacks suppressed
arm-smmu c600000.iommu: Unhandled context fault: fsr=0x402,
iova=0x5c0ec600, fsynr=0x320021, cbfrsynra=0x420, cb=5
arm-smmu c600000.iommu: FSR = 00000402 [Format=2 TF], SID=0x420
arm-smmu c600000.iommu: FSYNR0 = 00320021 [S1CBNDX=50 PNU PLVL=1]
arm-smmu c600000.iommu: Unhandled context fault: fsr=0x402,
iova=0x5c0d7800, fsynr=0x320021, cbfrsynra=0x420, cb=5
arm-smmu c600000.iommu: FSR = 00000402 [Format=2 TF], SID=0x420
and also failed initialisation of lontium lt9611uxc, gpu and dpu is
observed:
(binding MDSS components triggered by lt9611uxc have failed)

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm thin: fix use-after-free crash in dm_sm_register_threshold_callback
Fault inject on pool metadata device reports:
BUG: KASAN: use-after-free in dm_pool_register_metadata_threshold+0x40/0x80
Read of size 8 at addr ffff8881b9d50068 by task dmsetup/950
CPU: 7 PID: 950 Comm: dmsetup Tainted: G W 5.19.0-rc6 #1
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc33 04/01/2014
Call Trace:
<TASK>

This can be easily reproduced using:
echo offline > /sys/block/sda/device/state
dd if=/dev/zero of=/dev/mapper/thin bs=4k count=10
dmsetup load pool --table "0 20971520 thin-pool /dev/sda /dev/sdb 128 0 0"
If a metadata commit fails, the transaction will be aborted and the
metadata space maps will be destroyed. If a DM table reload then
happens for this failed thin-pool, a use-after-free will occur in
dm_sm_register_threshold_callback (called from
dm_pool_register_metadata_threshold).
Fix this by in dm_pool_register_metadata_threshold() by returning the
-EINVAL error if the thin-pool is in fail mode. Also fail pool_ctr()
with a new error message: "Error registering metadata threshold".

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: bpf: Add BHB mitigation to the epilogue for cBPF programs
A malicious BPF program may manipulate the branch history to influence
what the hardware speculates will happen next.
On exit from a BPF program, emit the BHB mititgation sequence.
This is only applied for 'classic' cBPF programs that are loaded by
seccomp.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: Fix vmalloc out-of-bounds write in fast_imageblit
This issue triggers when a userspace program does an ioctl
FBIOPUT_CON2FBMAP by passing console number and frame buffer number.
Ideally this maps console to frame buffer and updates the screen if
console is visible.
As part of mapping it has to do resize of console according to frame
buffer info. if this resize fails and returns from vc_do_resize() and
continues further. At this point console and new frame buffer are mapped
and sets display vars. Despite failure still it continue to proceed
updating the screen at later stages where vc_data is related to previous
frame buffer and frame buffer info and display vars are mapped to new
frame buffer and eventully leading to out-of-bounds write in
fast_imageblit(). This bheviour is excepted only when fg_console is
equal to requested console which is a visible console and updates screen
with invalid struct references in fbcon_putcs().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ARM: OMAP2+: Fix refcount leak in omap3xxx_prm_late_init
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix calltrace warning in amddrm_buddy_fini
The following call trace is observed when removing the amdgpu driver, which
is caused by that BOs allocated for psp are not freed until removing.
[61811.450562] RIP: 0010:amddrm_buddy_fini.cold+0x29/0x47 [amddrm_buddy]

For smu v13_0_2, if the GPU supports xgmi, refer to
commit f5c7e7797060 ("drm/amdgpu: Adjust removal control flow for smu v13_0_2"),
it will run gpu recover in AMDGPU_RESET_FOR_DEVICE_REMOVE mode when removing,
which makes all devices in hive list have hw reset but no resume except the
basic ip blocks, then other ip blocks will not call .hw_fini according to
ip_block.status.hw.
Since psp_free_shared_bufs just includes some software operations, so move
it to psp_sw_fini.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xen/privcmd: fix error exit of privcmd_ioctl_dm_op()
The error exit of privcmd_ioctl_dm_op() is calling unlock_pages()
potentially with pages being NULL, leading to a NULL dereference.
Additionally lock_pages() doesn't check for pin_user_pages_fast()
having been completely successful, resulting in potentially not
locking all pages into memory. This could result in sporadic failures
when using the related memory in user mode.
Fix all of that by calling unlock_pages() always with the real number
of pinned pages, which will be zero in case pages being NULL, and by
checking the number of pages pinned by pin_user_pages_fast() matching
the expected number of pages.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix kernel-infoleak in nilfs_ioctl_wrap_copy()
The ioctl helper function nilfs_ioctl_wrap_copy(), which exchanges a
metadata array to/from user space, may copy uninitialized buffer regions
to user space memory for read-only ioctl commands NILFS_IOCTL_GET_SUINFO
and NILFS_IOCTL_GET_CPINFO.
This can occur when the element size of the user space metadata given by
the v_size member of the argument nilfs_argv structure is larger than the
size of the metadata element (nilfs_suinfo structure or nilfs_cpinfo
structure) on the file system side.
KMSAN-enabled kernels detect this issue as follows:

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Limit access to parser->buffer when trace_get_user failed
When the length of the string written to set_ftrace_filter exceeds
FTRACE_BUFF_MAX, the following KASAN alarm will be triggered:
BUG: KASAN: slab-out-of-bounds in strsep+0x18c/0x1b0
Read of size 1 at addr ffff0000d00bd5ba by task ash/165
CPU: 1 UID: 0 PID: 165 Comm: ash Not tainted 6.16.0-g6bcdbd62bd56-dirty
Hardware name: linux,dummy-virt (DT)
Call trace:
show_stack+0x34/0x50 (C)
dump_stack_lvl+0xa0/0x158
print_address_description.constprop.0+0x88/0x398
print_report+0xb0/0x280
kasan_report+0xa4/0xf0
__asan_report_load1_noabort+0x20/0x30
strsep+0x18c/0x1b0
ftrace_process_regex.isra.0+0x100/0x2d8
ftrace_regex_release+0x484/0x618
__fput+0x364/0xa58
____fput+0x28/0x40
task_work_run+0x154/0x278
do_notify_resume+0x1f0/0x220
el0_svc+0xec/0xf0
el0t_64_sync_handler+0xa0/0xe8
el0t_64_sync+0x1ac/0x1b0
The reason is that trace_get_user will fail when processing a string
longer than FTRACE_BUFF_MAX, but not set the end of parser->buffer to 0.
Then an OOB access will be triggered in ftrace_regex_release->
ftrace_process_regex->strsep->strpbrk. We can solve this problem by
limiting access to parser->buffer when trace_get_user failed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: sdhci-pci: Fix possible memory leak caused by missing pci_dev_put()
pci_get_device() will increase the reference count for the returned
pci_dev. We need to use pci_dev_put() to decrease the reference count
before amd_probe() returns. There is no problem for the 'smbus_dev ==
NULL' branch because pci_dev_put() can also handle the NULL input
parameter case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: mcp2221: prevent a buffer overflow in mcp_smbus_write()
Smatch Warning:
drivers/hid/hid-mcp2221.c:388 mcp_smbus_write() error: __memcpy()
'&mcp->txbuf[5]' too small (59 vs 255)
drivers/hid/hid-mcp2221.c:388 mcp_smbus_write() error: __memcpy() 'buf'
too small (34 vs 255)
The 'len' variable can take a value between 0-255 as it can come from
data->block[0] and it is user data. So add an bound check to prevent a
buffer overflow in memcpy().

Summary
In the Linux kernel, the following vulnerability has been resolved:
batman-adv: fix OOB read/write in network-coding decode
batadv_nc_skb_decode_packet() trusts coded_len and checks only against
skb->len. XOR starts at sizeof(struct batadv_unicast_packet), reducing
payload headroom, and the source skb length is not verified, allowing an
out-of-bounds read and a small out-of-bounds write.
Validate that coded_len fits within the payload area of both destination
and source sk_buffs before XORing.

This is the classic same-broadcast-domain / WiFi-mesh injection scenario, i.e. Adjacent.\nAC:L - The attacker controls both halves of the primitive \u2014 the small buffered source frame (routed through the victim so send.c clones it into the decoding hash) and the oversized coded packet carrying coded_len, the MAC-based path key and the CRC packet_id, all computable offline. No race, no memory-layout guessing, and NC-capable nodes self-advertise via the BATADV_TVLV_NC OGM container, so the trigger is deterministic and repeatable.\nPR:N - batman-adv performs no authentication, encryption, or authorization on received frames; any node able to emit frames on the mesh segment reaches batadv_nc_recv_coded_packet(). No credentials, capabilities, or prior mesh membership approval are required.\nUI:N - The victim node processes the injected coded packet automatically in softirq receive context. No action by any user or administrator is needed beyond the mesh already running.\nS:U - The out-of-bounds read and write corrupt kernel heap memory within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The missing nc_packet-\u003eskb-\u003elen check allows reading roughly 1.4 KB of kernel heap past the buffered source skb, and because the data is XORed against attacker-known plaintext and then forwarded to an attacker-chosen orig_dest, the raw heap bytes are recovered remotely. This is a directly weaponizable kernel memory disclosure, not a bounded leak.\nI:H - The XOR overruns the destination skb by up to h_size (10) bytes with attacker-influenced content, landing in skb_shared_info (nr_frags, frag_list, dataref, gso fields) when tailroom is zero. Corrupting those fields drives bogus frag iteration and page puts in skb_release_data(), giving a heap-corruption/UAF primitive exploitable for control-flow hijack.\nA:H - The ~1.4 KB out-of-bounds read readily walks off the slab into unmapped memory, and the skb_shared_info overwrite corrupts refcounts and frag pointers, producing KASAN splats, oopses, or panics. The attacker can repeat this at will with no authentication."

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: don't skip expired elements during walk
There is an asymmetry between commit/abort and preparation phase if the
following conditions are met:
1. set is a verdict map ("1.2.3.4 : jump foo")
2. timeouts are enabled
In this case, following sequence is problematic:
1. element E in set S refers to chain C
2. userspace requests removal of set S
3. kernel does a set walk to decrement chain->use count for all elements
from preparation phase
4. kernel does another set walk to remove elements from the commit phase
(or another walk to do a chain->use increment for all elements from
abort phase)
If E has already expired in 1), it will be ignored during list walk, so its use count
won't have been changed.
Then, when set is culled, ->destroy callback will zap the element via
nf_tables_set_elem_destroy(), but this function is only safe for
elements that have been deactivated earlier from the preparation phase:
lack of earlier deactivate removes the element but leaks the chain use
count, which results in a WARN splat when the chain gets removed later,
plus a leak of the nft_chain structure.
Update pipapo_get() not to skip expired elements, otherwise flush
command reports bogus ENOENT errors.

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: csum: Fix OoB access in IP checksum code for negative lengths
Although commit c2c24edb1d9c ("arm64: csum: Fix pathological zero-length
calls") added an early return for zero-length input, syzkaller has
popped up with an example of a _negative_ length which causes an
undefined shift and an out-of-bounds read:

Summary
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Fix data-races around user->unix_inflight.
user->unix_inflight is changed under spin_lock(unix_gc_lock),
but too_many_unix_fds() reads it locklessly.
Let's annotate the write/read accesses to user->unix_inflight.
BUG: KCSAN: data-race in unix_attach_fds / unix_inflight

Use raw_smp_processor_id() instead of smp_processor_id().
Also use queue_work() across the driver instead of queue_work_on() thus
avoiding usage of smp_processor_id() when CONFIG_DEBUG_PREEMPT is enabled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: endpoint: pci-epf-test: Add NULL check for DMA channels before release
The fields dma_chan_tx and dma_chan_rx of the struct pci_epf_test can be
NULL even after EPF initialization. Then it is prudent to check that
they have non-NULL values before releasing the channels. Add the checks
in pci_epf_test_clean_dma_chan().
Without the checks, NULL pointer dereferences happen and they can lead
to a kernel panic in some cases:
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000050

The stale-stack values feeding `hdr.sector` and `struct vring_desc` are groomable with ordinary syscalls.\nPR:L - `vhost_vdpa_open()` and the vhost-vdpa ioctl handlers contain no `capable()`/`CAP_*` checks, so any user holding the device node can drive the full path, and in standard virtualization deployments that node is granted to an unprivileged VMM process. Only device *creation* needs admin, which is the normal host configuration, not an attacker step.\nUI:N - The attacker performs every step itself \u2014 map, truncate, kick the virtqueue \u2014 within its own process. No victim action or interaction is required.\nS:U - The corruption and disclosure occur in the host kernel that already governs the attacking process; this is standard local kernel compromise. No IOMMU, VM, or sandbox authority boundary is crossed by the bug itself.\nC:H - A silently-swallowed short pull causes `vdpasim_net_work()` to push a full PAGE_SIZE of the non-zeroed `kvmalloc` buffer `net-\u003ebuffer` into the attacker\u0027s RX ring, directly disclosing stale kernel heap. Additionally the uninitialized `hdr.sector` drives `vringh_iov_push_iotlb(..., blk-\u003ebuffer + offset, ...)` past the wrapped `VDPASIM_BLK_CAPACITY - start_sector` guard, giving an out-of-bounds kernel heap read echoed back to the attacker.\nI:H - In `vdpasim_blk_handle_req()` the uninitialized stack `hdr.sector` becomes the destination offset for `vringh_iov_pull_iotlb(..., blk-\u003ebuffer + (sector \u003c\u003c SECTOR_SHIFT), to_pull)`, an out-of-bounds kernel heap write of attacker-supplied data at a groomable offset. `__vringh_iov()` likewise builds iov entries whose `iov_base`/`iov_len` come from uninitialized kernel stack, giving further attacker-influenced memory corruption.\nA:H - Descriptors and request headers fabricated from uninitialized kernel stack yield bogus IOVAs and lengths up to 4 GB, and the resulting out-of-bounds heap accesses and invalid `pfn_to_page()`/page translations cause kernel oops or panic. The condition is repeatable at will from a single unprivileged process."

Summary
In the Linux kernel, the following vulnerability has been resolved:
loop: Check for overflow while configuring loop
The userspace can configure a loop using an ioctl call, wherein
a configuration of type loop_config is passed (see lo_ioctl()'s
case on line 1550 of drivers/block/loop.c). This proceeds to call
loop_configure() which in turn calls loop_set_status_from_info()
(see line 1050 of loop.c), passing &config->info which is of type
loop_info64*. This function then sets the appropriate values, like
the offset.
loop_device has lo_offset of type loff_t (see line 52 of loop.c),
which is typdef-chained to long long, whereas loop_info64 has
lo_offset of type __u64 (see line 56 of include/uapi/linux/loop.h).
The function directly copies offset from info to the device as
follows (See line 980 of loop.c):
lo->lo_offset = info->lo_offset;
This results in an overflow, which triggers a warning in iomap_iter()
due to a call to iomap_iter_done() which has:
WARN_ON_ONCE(iter->iomap.offset > iter->pos);
Thus, check for negative value during loop_set_status_from_info().

Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock: Do not allow binding to VMADDR_PORT_ANY
It is possible for a vsock to autobind to VMADDR_PORT_ANY. This can
cause a use-after-free when a connection is made to the bound socket.
The socket returned by accept() also has port VMADDR_PORT_ANY but is not
on the list of unbound sockets. Binding it will result in an extra
refcount decrement similar to the one fixed in fcdd2242c023 (vsock: Keep
the binding until socket destruction).
Modify the check in __vsock_bind_connectible() to also prevent binding
to VMADDR_PORT_ANY.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: wil6210: debugfs: fix uninitialized variable use in `wil_write_file_wmi()`
Commit 7a4836560a61 changes simple_write_to_buffer() with memdup_user()
but it forgets to change the value to be returned that came from
simple_write_to_buffer() call. It results in the following warning:
warning: variable 'rc' is uninitialized when used here [-Wuninitialized]
return rc;
^~
Remove rc variable and just return the passed in length if the
memdup_user() succeeds.

Summary
In the Linux kernel, the following vulnerability has been resolved:
octeontx2-pf: Fix potential use after free in otx2_tc_add_flow()
This code calls kfree_rcu(new_node, rcu) and then dereferences "new_node"
and then dereferences it on the next line. Two lines later, we take
a mutex so I don't think this is an RCU safe region. Re-order it to do
the dereferences before queuing up the free.

"lang": "en",
"value": "AV:L - The vulnerable path is reached only through a local `RTM_NEWTFILTER` netlink message installing a tc flower filter with a police action on an octeontx2 PF/VF/representor netdev. There is no remote packet-processing path into `otx2_tc_add_flow()`.\nAC:L - The attacker deterministically forces the `free_leaf:` error path by installing police-action flower rules until MCAM/mbox resources are exhausted, and widens the RCU grace-period window at will by contending `nic-\u003embox.lock` from a second thread so `mutex_lock()` sleeps. Both the free and the reclaim/spray side are under attacker control.\nPR:L - Only CAP_NET_ADMIN over the netns owning the device is needed, and `otx2_setup_tc` is shared by the VF (`otx2_vf.c:535`) and representor (`rep.c:495`) drivers, whose netdevs are commonly delegated into container netns owned by unprivileged user namespaces where container-root holds CAP_NET_ADMIN with no init-namespace privilege.\nUI:N - The entire sequence is driven by the attacker\u0027s own netlink filter-install requests. No victim action or cooperation is involved.\nS:U - The use-after-free corrupts kernel heap and driver state within the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed `struct otx2_tc_flow` is read back after reclaim, giving a read primitive over whatever slab object replaced it, and the stale `rq`/`leaf_profile` values are further exposed to userspace through `netdev_err()` kernel-log messages.\nI:H - `__clear_bit(new_node-\u003erq, \u0026nic-\u003erq_bmap)` uses a UAF-derived u16 index against a single `unsigned long`, yielding an out-of-bounds bit clear up to ~8 KB into and past `struct otx2_nic` (mbox state, queue and function pointers), and the stale `leaf_profile` makes firmware tear down another flow\u0027s hardware policer, silently defeating QoS/rate-limit enforcement.\nA:H - A use-after-free on a slab object combined with an out-of-bounds bit clear into the driver\u0027s private structure reliably oopses the kernel or wedges the NIC\u0027s mailbox/queue state, and the attacker can repeat it at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: Fix memory leak in devm_clk_notifier_register()
devm_clk_notifier_register() allocates a devres resource for clk
notifier but didn't register that to the device, so the notifier didn't
get unregistered on device detach and the allocated resource was leaked.
Fix the issue by registering the resource through devres_add().
This issue was found with kmemleak on a Chromebook.

In the Linux kernel, the following vulnerability has been resolved:
media: rc: fix races with imon_disconnect()
Syzbot reports a KASAN issue as below:

The iMON driver improperly releases the usb_device reference in
imon_disconnect without coordinating with active users of the
device.
Specifically, the fields usbdev_intf0 and usbdev_intf1 are not
protected by the users counter (ictx->users). During probe,
imon_init_intf0 or imon_init_intf1 increments the usb_device
reference count depending on the interface. However, during
disconnect, usb_put_dev is called unconditionally, regardless of
actual usage.
As a result, if vfd_write or other operations are still in
progress after disconnect, this can lead to a use-after-free of
the usb_device pointer.
Thread 1 vfd_write Thread 2 imon_disconnect

while

if
pipe = usb_sndintpipe(
ictx->usbdev_intf0) UAF
else
pipe = usb_sndctrlpipe(
ictx->usbdev_intf0, 0) UAF
Guard access to usbdev_intf0 and usbdev_intf1 after disconnect by
checking ictx->disconnected in all writer paths. Add early return
with -ENODEV in send_packet(), vfd_write(), lcd_write() and
display_open() if the device is no longer present.
Set and read ictx->disconnected under ictx->lock to ensure memory
synchronization. Acquire the lock in imon_disconnect() before setting
the flag to synchronize with any ongoing operations.
Ensure writers exit early and safely after disconnect before the USB
core proceeds with cleanup.

The disconnect that frees the `usb_device` is a triggering condition the attacker supplies (their own removable/emulated iMON device or an unplug event), not the attack interface itself.\nAC:L - The attacker controls both sides of the race: they drive an unbounded loop of `write()` calls that hold `ictx-\u003elock` for seconds at a time (`send_packet` waits up to 10 s per packet, six packets per write) while triggering device removal, giving an extremely wide and repeatable window. Syzkaller reproduces it, and failed attempts are harmless, so it can be retried until it lands.\nPR:L - No capability, `CAP_SYS_ADMIN`, or other privilege check exists anywhere on the path \u2014 `display_open()` only checks `display_supported`/`display_isopen`, and `vfd_write`/`lcd_write` go straight to `send_packet()`. Any unprivileged process able to open the display node (routinely group-accessible on media/HTPC systems, and the node the LIRC/LCDproc userspace stack writes to) can trigger it.\nUI:N - The attacker\u0027s own process performs the writes, and the disconnect side is produced by the attacker\u0027s device or unplug action rather than by a victim. No action by another user is needed at any point.\nS:U - The use-after-free corrupts kernel memory within the same kernel security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - The freed `struct usb_device` is read via `__create_pipe()` (`dev-\u003edevnum`) and then throughout `usb_submit_urb()` (`dev-\u003estate`, `dev-\u003eep_out[]`, `dev-\u003ebus`), so an attacker who reclaims the slab object can read back kernel data and pointers, and the UAF is a general primitive for arbitrary memory disclosure.\nI:H - The stale pointer is stored into the URB and submitted, causing `usb_get_dev(urb-\u003edev)` to write (atomic increment) into freed memory and `bus_to_hcd(urb-\u003edev-\u003ebus)-\u003edriver-\u003eurb_enqueue()` to make an indirect call through a chain rooted in attacker-reclaimable memory \u2014 a control-flow hijack and arbitrary-write primitive.\nA:H - Even without heap grooming, dereferencing and submitting an URB against a freed `usb_device` reliably produces a KASAN splat, oops, or panic, as shown in the syzbot report, and the attacker can repeat it at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
perf/core: Fix perf_output_begin parameter is incorrectly invoked in perf_event_bpf_output
syzkaller reportes a KASAN issue with stack-out-of-bounds.
The call trace is as follows:

commit 267fb27352b6 ("perf: Reduce stack usage of perf_output_begin()")
use on-stack struct perf_sample_data of the caller function.
However, perf_event_bpf_output uses incorrect parameter to convert
small-sized data (struct perf_bpf_event) into large-sized data
(struct perf_sample_data), which causes memory overwriting occurs in
__perf_event_header__init_id.

Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: bcm-qspi: return error if neither hif_mspi nor mspi is available
If neither a "hif_mspi" nor "mspi" resource is present, the driver will
just early exit in probe but still return success. Apart from not doing
anything meaningful, this would then also lead to a null pointer access
on removal, as platform_get_drvdata() would return NULL, which it would
then try to dereference when trying to unregister the spi master.
Fix this by unconditionally calling devm_ioremap_resource(), as it can
handle a NULL res and will then return a viable ERR_PTR() if we get one.
The "return 0;" was previously a "goto qspi_resource_err;" where then
ret was returned, but since ret was still initialized to 0 at this place
this was a valid conversion in 63c5395bb7a9 ("spi: bcm-qspi: Fix
use-after-free on unbind"). The issue was not introduced by this commit,
only made more obvious.

Summary
In the Linux kernel, the following vulnerability has been resolved:
video: fbdev: amba-clcd: Fix refcount leak bugs
In clcdfb_of_init_display(), we should call of_node_put() for the
references returned by of_graph_get_next_endpoint() and
of_graph_get_remote_port_parent() which have increased the refcount.
Besides, we should call of_node_put() both in fail path or when
the references are not used anymore.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/drv: Fix potential memory leak in drm_dev_init()
drm_dev_init() will add drm_dev_init_release() as a callback. When
drmm_add_action() failed, the release function won't be added. As the
result, the ref cnt added by device_get() in drm_dev_init() won't be put
by drm_dev_init_release(), which leads to the memleak. Use
drmm_add_action_or_reset() instead of drmm_add_action() to prevent
memleak.

not checked. As a result, it causes null-ptr-deref while removing
the module, because transport_remove_device() is called to remove
the device that was not added.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: qrtr: start MHI channel after endpoit creation
MHI channel may generates event/interrupt right after enabling.
It may leads to 2 race conditions issues.
1)
Such event may be dropped by qcom_mhi_qrtr_dl_callback() at check:
if (!qdev || mhi_res->transaction_status)
return;
Because dev_set_drvdata(&mhi_dev->dev, qdev) may be not performed at
this moment. In this situation qrtr-ns will be unable to enumerate
services in device.
---------------------------------------------------------------
2)
Such event may come at the moment after dev_set_drvdata() and
before qrtr_endpoint_register(). In this case kernel will panic with
accessing wrong pointer at qcom_mhi_qrtr_dl_callback():
rc = qrtr_endpoint_post(&qdev->ep, mhi_res->buf_addr,
mhi_res->bytes_xferd);
Because endpoint is not created yet.
--------------------------------------------------------------
So move mhi_prepare_for_transfer_autoqueue after endpoint creation
to fix it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Fix use-after-free in l2cap_sock_cleanup_listen()
syzbot reported the splat below without a repro.
In the splat, a single thread calling bt_accept_dequeue() freed sk
and touched it after that.
The root cause would be the racy l2cap_sock_cleanup_listen() call
added by the cited commit.
bt_accept_dequeue() is called under lock_sock() except for
l2cap_sock_release().
Two threads could see the same socket during the list iteration
in bt_accept_dequeue():
CPU1 CPU2 (close())
---- ----
sock_hold(sk) sock_hold(sk);
lock_sock(sk) <-- block close()
sock_put(sk)
bt_accept_unlink(sk)
sock_put(sk) <-- refcnt by bt_accept_enqueue()
release_sock(sk)
lock_sock(sk)
sock_put(sk)
bt_accept_unlink(sk)
sock_put(sk) <-- last refcnt
bt_accept_unlink(sk) <-- UAF
Depending on the timing, the other thread could show up in the
"Freed by task" part.
Let's call l2cap_sock_cleanup_listen() under lock_sock() in
l2cap_sock_release().

"value": "AV:A - The vulnerability lives in the Bluetooth L2CAP socket layer, and the objects that get freed and reused are child sockets that only ever exist because an adjacent Bluetooth peer established L2CAP connections to the listening PSM (`l2cap_connect_cfm` \u2192 `l2cap_sock_new_connection_cb`). The attack surface therefore spans the Bluetooth piconet/radio range.\nAC:L - The attacker controls both sides of the race \u2014 one thread blocked in `accept()` on the listening L2CAP socket and another calling `close()` on the same fd \u2014 and can retry indefinitely while keeping many pending children queued to widen the `bt_accept_dequeue()` iteration window. Nothing about the race depends on conditions outside the attacker\u0027s influence.\nPR:L - `l2cap_sock_create()` requires no capability for `SOCK_SEQPACKET`/`SOCK_STREAM` (only `SOCK_RAW` gates on `CAP_NET_RAW`), and binding a dynamic PSM \u2265 0x1001 bypasses the `CAP_NET_BIND_SERVICE` check, so an ordinary unprivileged local user can create, listen on, accept from and close the socket that triggers the race.\nUI:N - The race is driven entirely by the attacker\u0027s own threads performing `accept()` and `close()` syscalls plus inbound L2CAP connections; no victim action is needed.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The freed `struct sock` is read after free (`debug_spin_lock_before`/`release_sock`) and lives in a general kmalloc cache, so an attacker who sprays replacement objects into the freed slot can read back attacker-chosen or sensitive kernel data through the stale socket, giving an arbitrary-read path.\nI:H - After the free the kernel still writes into the object \u2014 `list_del_init()` on the freed `accept_q` node (an unlink write of attacker-groomable pointers), `sk_acceptq_removed()`, a refcount decrement, and spinlock stores \u2014 yielding a write primitive into reclaimed heap memory that is exploitable for control-flow hijack and privilege escalation.\nA:H - The bug is a confirmed slab use-after-free (syzbot KASAN splat) that corrupts the parent\u0027s accept queue list and takes a spinlock on freed memory, reliably producing an oops/panic and unbootable-level kernel instability."

Summary
In the Linux kernel, the following vulnerability has been resolved:
erofs: Fix detection of atomic context
Current check for atomic context is not sufficient as
z_erofs_decompressqueue_endio can be called under rcu lock
from blk_mq_flush_plug_list(). See the stacktrace [1]
In such case we should hand off the decompression work for async
processing rather than trying to do sync decompression in current
context. Patch fixes the detection by checking for
rcu_read_lock_any_held() and while at it use more appropriate
!in_task() check than in_atomic().
Background: Historically erofs would always schedule a kworker for
decompression which would incur the scheduling cost regardless of
the context. But z_erofs_decompressqueue_endio() may not always
be in atomic context and we could actually benefit from doing the
decompression in z_erofs_decompressqueue_endio() if we are in
thread context, for example when running with dm-verity.
This optimization was later added in patch [2] which has shown
improvement in performance benchmarks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: Don't finalize CSA in IBSS mode if state is disconnected
When we are not connected to a channel, sending channel "switch"
announcement doesn't make any sense.
The BSS list is empty in that case. This causes the for loop in
cfg80211_get_bss() to be bypassed, so the function returns NULL
(check line 1424 of net/wireless/scan.c), causing the WARN_ON()
in ieee80211_ibss_csa_beacon() to get triggered (check line 500
of net/mac80211/ibss.c), which was consequently reported on the
syzkaller dashboard.
Thus, check if we have an existing connection before generating
the CSA beacon in ieee80211_ibss_finish_csa().

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: uvcvideo: Fix 1-byte out-of-bounds read in uvc_parse_format()
The buffer length check before calling uvc_parse_format() only ensured
that the buffer has at least 3 bytes (buflen > 2), buf the function
accesses buffer[3], requiring at least 4 bytes.
This can lead to an out-of-bounds read if the buffer has exactly 3 bytes.
Fix it by checking that the buffer has at least 4 bytes in
uvc_parse_format().

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/sun4i: dsi: Prevent underflow when computing packet sizes
Currently, the packet overhead is subtracted using unsigned arithmetic.
With a short sync pulse, this could underflow and wrap around to near
the maximal u16 value. Fix this by using signed subtraction. The call to
max() will correctly handle any negative numbers that are produced.
Apply the same fix to the other timings, even though those subtractions
are less likely to underflow.

fs/ntfs3: Enhance sanity check while generating attr_list
ni_create_attr_list uses WARN_ON to catch error cases while generating
attribute list, which only prints out stack trace and may not be enough.
This repalces them with more proper error handling flow.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: amd_sfh: Fix for shift-out-of-bounds
Shift operation of 'exp' and 'shift' variables exceeds the maximum number
of shift values in the u32 range leading to UBSAN shift-out-of-bounds.

==================================================================
The problem is that the inode contains an xattr entry with ea_inum of 15
when cleaning up an orphan inode <15>. When evict inode <15>, the reference
counting of the corresponding EA inode is decreased. When EA inode <15> is
found by find_inode_fast() in __ext4_iget(), it is found that the EA inode
holds the I_FREEING flag and waits for the EA inode to complete deletion.
As a result, when inode <15> is being deleted, we wait for inode <15> to
complete the deletion, resulting in an infinite loop and triggering Hung
Task. To solve this problem, we only need to check whether the ino of EA
inode and parent is the same before getting EA inode.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm raid: fix address sanitizer warning in raid_resume
There is a KASAN warning in raid_resume when running the lvm test
lvconvert-raid.sh. The reason for the warning is that mddev->raid_disks
is greater than rs->raid_disks, so the loop touches one entry beyond
the allocated length.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rcu/rcuscale: Stop kfree_scale_thread thread(s) after unloading rcuscale
Running the 'kfree_rcu_test' test case [1] results in a splat [2].
The root cause is the kfree_scale_thread thread(s) continue running
after unloading the rcuscale module. This commit fixes that isue by
invoking kfree_scale_cleanup() from rcu_scale_cleanup() when removing
the rcuscale module.
[1] modprobe rcuscale kfree_rcu_test=1

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: wilc1000: avoid buffer overflow in WID string configuration
Fix the following copy overflow warning identified by Smatch checker.
drivers/net/wireless/microchip/wilc1000/wlan_cfg.c:184 wilc_wlan_parse_response_frame()
error: '__memcpy()' 'cfg->s[i]->str' copy overflow (512 vs 65537)
This patch introduces size check before accessing the memory buffer.
The checks are base on the WID type of received data from the firmware.
For WID string configuration, the size limit is determined by individual
element size in 'struct wilc_cfg_str_vals' that is maintained in 'len' field
of 'struct wilc_cfg_str'.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: Intel: cnl: Do not process IPC reply before firmware boot
It is not yet clear, but it is possible to create a firmware so broken
that it will send a reply message before a FW_READY message (it is not
yet clear if FW_READY will arrive later).
Since the reply_data is allocated only after the FW_READY message, this
will lead to a NULL pointer dereference if not filtered out.
The issue was reported with IPC4 firmware but the same condition is present
for IPC3.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: asus: fix UAF via HID_CLAIMED_INPUT validation
After hid_hw_start() is called hidinput_connect() will eventually be
called to set up the device with the input layer since the
HID_CONNECT_DEFAULT connect mask is used. During hidinput_connect()
all input and output reports are processed and corresponding hid_inputs
are allocated and configured via hidinput_configure_usages(). This
process involves slot tagging report fields and configuring usages
by setting relevant bits in the capability bitmaps. However it is possible
that the capability bitmaps are not set at all leading to the subsequent
hidinput_has_been_populated() check to fail leading to the freeing of the
hid_input and the underlying input device.
This becomes problematic because a malicious HID device like a
ASUS ROG N-Key keyboard can trigger the above scenario via a
specially crafted descriptor which then leads to a user-after-free
when the name of the freed input device is written to later on after
hid_hw_start(). Below, report 93 intentionally utilises the
HID_UP_UNDEFINED Usage Page which is skipped during usage
configuration, leading to the frees.

Summary
In the Linux kernel, the following vulnerability has been resolved:
soundwire: revisit driver bind/unbind and callbacks
In the SoundWire probe, we store a pointer from the driver ops into
the 'slave' structure. This can lead to kernel oopses when unbinding
codec drivers, e.g. with the following sequence to remove machine
driver and codec driver.
/sbin/modprobe -r snd_soc_sof_sdw
/sbin/modprobe -r snd_soc_rt711
The full details can be found in the BugLink below, for reference the
two following examples show different cases of driver ops/callbacks
being invoked after the driver .remove().

This was not detected earlier in Intel tests since the tests first
remove the parent PCI device and shut down the bus. The sequence
above is a corner case which keeps the bus operational but without a
driver bound.
While trying to solve this kernel oopses, it became clear that the
existing SoundWire bus does not deal well with the unbind case.
Commit 528be501b7d4a ("soundwire: sdw_slave: add probe_complete structure and new fields")
added a 'probed' status variable and a 'probe_complete'
struct completion. This status is however not reset on remove and
likewise the 'probe complete' is not re-initialized, so the
bind/unbind/bind test cases would fail. The timeout used before the
'update_status' callback was also a bad idea in hindsight, there
should really be no timing assumption as to if and when a driver is
bound to a device.
An initial draft was based on device_lock() and device_unlock() was
tested. This proved too complicated, with deadlocks created during the
suspend-resume sequences, which also use the same device_lock/unlock()
as the bind/unbind sequences. On a CometLake device, a bad DSDT/BIOS
caused spurious resumes and the use of device_lock() caused hangs
during suspend. After multiple weeks or testing and painful
reverse-engineering of deadlocks on different devices, we looked for
alternatives that did not interfere with the device core.
A bus notifier was used successfully to keep track of DRIVER_BOUND and
DRIVER_UNBIND events. This solved the bind-unbind-bind case in tests,
but it can still be defeated with a theoretical corner case where the
memory is freed by a .remove while the callback is in use. The
notifier only helps make sure the driver callbacks are valid, but not
that the memory allocated in probe remains valid while the callbacks
are invoked.
This patch suggests the introduction of a new 'sdw_dev_lock' mutex
protecting probe/remove and all driver callbacks. Since this mutex is
'local' to SoundWire only, it does not interfere with existing locks
and does not create deadlocks. In addition, this patch removes the
'probe_complete' completion, instead we directly invoke the
'update_status' from the probe routine. That removes any sort of
timing dependency and a much better support for the device/driver
model, the driver could be bound before the bus started, or eons after
the bus started and the hardware would be properly initialized in all
cases.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: ipset: add the missing IP_SET_HASH_WITH_NET0 macro for ip_set_hash_netportnet.c
The missing IP_SET_HASH_WITH_NET0 macro in ip_set_hash_netportnet can
lead to the use of wrong `CIDR_POS(c)` for calculating array offsets,
which can lead to integer underflow. As a result, it leads to slab
out-of-bound access.
This patch adds back the IP_SET_HASH_WITH_NET0 macro to
ip_set_hash_netportnet to address the issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
misc: fastrpc: fix memory corruption on open
The probe session-duplication overflow check incremented the session
count also when there were no more available sessions so that memory
beyond the fixed-size slab-allocated session array could be corrupted in
fastrpc_session_alloc() on open().

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: macvlan: fix memory leaks of macvlan_common_newlink
kmemleak reports memory leaks in macvlan_common_newlink, as follows:
ip link add link eth0 name .. type macvlan mode source macaddr add
<MAC-ADDR>
kmemleak reports:
unreferenced object 0xffff8880109bb140 (size 64):
comm "ip", pid 284, jiffies 4294986150 (age 430.108s)
hex dump (first 32 bytes):
00 00 00 00 00 00 00 00 b8 aa 5a 12 80 88 ff ff ..........Z.....
80 1b fa 0d 80 88 ff ff 1e ff ac af c7 c1 6b 6b ..............kk
backtrace:
[<ffffffff813e06a7>] kmem_cache_alloc_trace+0x1c7/0x300
[<ffffffff81b66025>] macvlan_hash_add_source+0x45/0xc0
[<ffffffff81b66a67>] macvlan_changelink_sources+0xd7/0x170
[<ffffffff81b6775c>] macvlan_common_newlink+0x38c/0x5a0
[<ffffffff81b6797e>] macvlan_newlink+0xe/0x20
[<ffffffff81d97f8f>] __rtnl_newlink+0x7af/0xa50
[<ffffffff81d98278>] rtnl_newlink+0x48/0x70
...
In the scenario where the macvlan mode is configured as 'source',
macvlan_changelink_sources() will be execured to reconfigure list of
remote source mac addresses, at the same time, if register_netdevice()
return an error, the resource generated by macvlan_changelink_sources()
is not cleaned up.
Using this patch, in the case of an error, it will execute
macvlan_flush_sources() to ensure that the resource is cleaned up.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mwifiex: avoid possible NULL skb pointer dereference
In 'mwifiex_handle_uap_rx_forward()', always check the value
returned by 'skb_copy()' to avoid potential NULL pointer
dereference in 'mwifiex_uap_queue_bridged_pkt()', and drop
original skb in case of copying failure.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: fix use-after-free when rescheduling brcmf_btcoex_info work
The brcmf_btcoex_detach() only shuts down the btcoex timer, if the
flag timer_on is false. However, the brcmf_btcoex_timerfunc(), which
runs as timer handler, sets timer_on to false. This creates critical
race conditions:
1.If brcmf_btcoex_detach() is called while brcmf_btcoex_timerfunc()
is executing, it may observe timer_on as false and skip the call to
timer_shutdown_sync().
2.The brcmf_btcoex_timerfunc() may then reschedule the brcmf_btcoex_info
worker after the cancel_work_sync() has been executed, resulting in
use-after-free bugs.
The use-after-free bugs occur in two distinct scenarios, depending on
the timing of when the brcmf_btcoex_info struct is freed relative to
the execution of its worker thread.
Scenario 1: Freed before the worker is scheduled
The brcmf_btcoex_info is deallocated before the worker is scheduled.
A race condition can occur when schedule_work(&bt_local->work) is
called after the target memory has been freed. The sequence of events
is detailed below:
CPU0 | CPU1
brcmf_btcoex_detach | brcmf_btcoex_timerfunc
| bt_local->timer_on = false;
if (cfg->btcoex->timer_on) |
... |
cancel_work_sync(); |
... |
kfree(cfg->btcoex); // FREE |
| schedule_work(&bt_local->work); // USE
Scenario 2: Freed after the worker is scheduled
The brcmf_btcoex_info is freed after the worker has been scheduled
but before or during its execution. In this case, statements within
the brcmf_btcoex_handler() — such as the container_of macro and
subsequent dereferences of the brcmf_btcoex_info object will cause
a use-after-free access. The following timeline illustrates this
scenario:
CPU0 | CPU1
brcmf_btcoex_detach | brcmf_btcoex_timerfunc
| bt_local->timer_on = false;
if (cfg->btcoex->timer_on) |
... |
cancel_work_sync(); |
... | schedule_work(); // Reschedule
|
kfree(cfg->btcoex); // FREE | brcmf_btcoex_handler() // Worker
/* | btci = container_of(....); // USE
The kfree() above could | ...
also occur at any point | btci-> // USE
during the worker's execution|
*/ |
To resolve the race conditions, drop the conditional check and call
timer_shutdown_sync() directly. It can deactivate the timer reliably,
regardless of its current state. Once stopped, the timer_on state is
then set to false.

Although an adjacent attacker can induce the free side by halting the firmware (`BRCMF_D2H_DEV_FWHALT` \u2192 `brcmf_fw_crashed()` \u2192 `brcmf_bus_reset()`), a single attacker capable of both halves of the race operates locally.\nAC:L - The attacker controls both sides: the crit-proto `duration` makes the handler arm the timer at a deterministic `jiffies + 2s`, so the callback\u0027s execution moment is known in advance, and the same actor drives the teardown (bus reset / driver unbind / firmware halt) to land inside it. The attempt is cheap to repeat in a loop until the window is hit, and the freed `kmalloc-192` object can be sprayed with standard heap-grooming syscalls.\nPR:L - `NL80211_CMD_CRIT_PROTOCOL_START` carries `GENL_UNS_ADMIN_PERM` (CAP_NET_ADMIN), which on Android and embedded targets is held by the confined non-root Wi-Fi/supplicant service account rather than by real root in the init namespace, and the free side can be reached without root by making the firmware halt. Basic account-level access with that delegated network capability is sufficient, so this is Low rather than High.\nUI:N - The attacker issues the crit-proto start and triggers the teardown itself; no victim needs to mount a filesystem, open a file, or take any other action for the use-after-free to occur.\nS:U - The freed object, the corrupted slab, and the hijacked workqueue dispatch all live within the kernel\u0027s own security authority, with no crossing into a hypervisor, IOMMU, or other protection domain.\nC:H - The use-after-free lets the attacker reoccupy the freed `brcmf_btcoex_info` slot, after which `brcmf_btcoex_handler()` dereferences attacker-chosen `btci-\u003evif`, `btci-\u003evif-\u003eifp`, and `btci-\u003ecfg-\u003epub` pointers, yielding an arbitrary kernel-memory read primitive and disclosure of kernel addresses.\nI:H - `process_one_work()` loads `work-\u003efunc` out of the freed structure and calls it (`worker-\u003ecurrent_func = work-\u003efunc; worker-\u003ecurrent_func(work);`), so a resprayed slot gives a controlled indirect call, and `schedule_work()` on freed memory additionally corrupts worker-pool list linkage \u2014 a full control-flow-hijack and arbitrary-write primitive.\nA:H - Even without successful grooming, scheduling and executing work on a kfree\u0027d object dereferences poisoned/recycled memory and reliably produces a KASAN splat, oops, or kernel panic, taking the system down."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dcb: choose correct policy to parse DCB_ATTR_BCN
The dcbnl_bcn_setcfg uses erroneous policy to parse tb[DCB_ATTR_BCN],
which is introduced in commit 859ee3c43812 ("DCB: Add support for DCB
BCN"). Please see the comment in below code
static int dcbnl_bcn_setcfg(...)
{
...
ret = nla_parse_nested_deprecated(..., dcbnl_pfc_up_nest, .. )
// !!! dcbnl_pfc_up_nest for attributes
// DCB_PFC_UP_ATTR_0 to DCB_PFC_UP_ATTR_ALL in enum dcbnl_pfc_up_attrs
...
for (i = DCB_BCN_ATTR_RP_0; i <= DCB_BCN_ATTR_RP_7; i++) {
// !!! DCB_BCN_ATTR_RP_0 to DCB_BCN_ATTR_RP_7 in enum dcbnl_bcn_attrs
...
value_byte = nla_get_u8(data[i]);
...
}
...
for (i = DCB_BCN_ATTR_BCNA_0; i <= DCB_BCN_ATTR_RI; i++) {
// !!! DCB_BCN_ATTR_BCNA_0 to DCB_BCN_ATTR_RI in enum dcbnl_bcn_attrs
...
value_int = nla_get_u32(data[i]);
...
}
...
}
That is, the nla_parse_nested_deprecated uses dcbnl_pfc_up_nest
attributes to parse nlattr defined in dcbnl_pfc_up_attrs. But the
following access code fetch each nlattr as dcbnl_bcn_attrs attributes.
By looking up the associated nla_policy for dcbnl_bcn_attrs. We can find
the beginning part of these two policies are "same".
static const struct nla_policy dcbnl_pfc_up_nest[...] = {
[DCB_PFC_UP_ATTR_0] = {.type = NLA_U8},
[DCB_PFC_UP_ATTR_1] = {.type = NLA_U8},
[DCB_PFC_UP_ATTR_2] = {.type = NLA_U8},
[DCB_PFC_UP_ATTR_3] = {.type = NLA_U8},
[DCB_PFC_UP_ATTR_4] = {.type = NLA_U8},
[DCB_PFC_UP_ATTR_5] = {.type = NLA_U8},
[DCB_PFC_UP_ATTR_6] = {.type = NLA_U8},
[DCB_PFC_UP_ATTR_7] = {.type = NLA_U8},
[DCB_PFC_UP_ATTR_ALL] = {.type = NLA_FLAG},
};
static const struct nla_policy dcbnl_bcn_nest[...] = {
[DCB_BCN_ATTR_RP_0] = {.type = NLA_U8},
[DCB_BCN_ATTR_RP_1] = {.type = NLA_U8},
[DCB_BCN_ATTR_RP_2] = {.type = NLA_U8},
[DCB_BCN_ATTR_RP_3] = {.type = NLA_U8},
[DCB_BCN_ATTR_RP_4] = {.type = NLA_U8},
[DCB_BCN_ATTR_RP_5] = {.type = NLA_U8},
[DCB_BCN_ATTR_RP_6] = {.type = NLA_U8},
[DCB_BCN_ATTR_RP_7] = {.type = NLA_U8},
[DCB_BCN_ATTR_RP_ALL] = {.type = NLA_FLAG},
// from here is somewhat different
[DCB_BCN_ATTR_BCNA_0] = {.type = NLA_U32},
...
[DCB_BCN_ATTR_ALL] = {.type = NLA_FLAG},
};
Therefore, the current code is buggy and this
nla_parse_nested_deprecated could overflow the dcbnl_pfc_up_nest and use
the adjacent nla_policy to parse attributes from DCB_BCN_ATTR_BCNA_0.
Hence use the correct policy dcbnl_bcn_nest to parse the nested
tb[DCB_ATTR_BCN] TLV.

Summary
In the Linux kernel, the following vulnerability has been resolved:
kprobes: don't call disarm_kprobe() for disabled kprobes
The assumption in __disable_kprobe() is wrong, and it could try to disarm
an already disarmed kprobe and fire the WARN_ONCE() below. [0] We can
easily reproduce this issue.
1. Write 0 to /sys/kernel/debug/kprobes/enabled.
# echo 0 > /sys/kernel/debug/kprobes/enabled
2. Run execsnoop. At this time, one kprobe is disabled.
# /usr/share/bcc/tools/execsnoop &
[1] 2460
PCOMM PID PPID RET ARGS
# cat /sys/kernel/debug/kprobes/list
ffffffff91345650 r __x64_sys_execve+0x0 [FTRACE]
ffffffff91345650 k __x64_sys_execve+0x0 [DISABLED][FTRACE]
3. Write 1 to /sys/kernel/debug/kprobes/enabled, which changes
kprobes_all_disarmed to false but does not arm the disabled kprobe.
# echo 1 > /sys/kernel/debug/kprobes/enabled
# cat /sys/kernel/debug/kprobes/list
ffffffff91345650 r __x64_sys_execve+0x0 [FTRACE]
ffffffff91345650 k __x64_sys_execve+0x0 [DISABLED][FTRACE]
4. Kill execsnoop, when __disable_kprobe() calls disarm_kprobe() for the
disabled kprobe and hits the WARN_ONCE() in __disarm_kprobe_ftrace().
# fg
/usr/share/bcc/tools/execsnoop
^C
Actually, WARN_ONCE() is fired twice, and __unregister_kprobe_top() misses
some cleanups and leaves the aggregated kprobe in the hash table. Then,
__unregister_trace_kprobe() initialises tk->rp.kp.list and creates an
infinite loop like this.
aggregated kprobe.list -> kprobe.list -.
^ |
'.__.'
In this situation, these commands fall into the infinite loop and result
in RCU stall or soft lockup.
cat /sys/kernel/debug/kprobes/list : show_kprobe_addr() enters into the
infinite loop with RCU.
/usr/share/bcc/tools/execsnoop : warn_kprobe_rereg() holds kprobe_mutex,
and __get_valid_kprobe() is stuck in
the loop.
To avoid the issue, make sure we don't call disarm_kprobe() for disabled
kprobes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tty: n_gsm: Don't block input queue by waiting MSC
Currently gsm_queue() processes incoming frames and when opening
a DLC channel it calls gsm_dlci_open() which calls gsm_modem_update().
If basic mode is used it calls gsm_modem_upd_via_msc() and it
cannot block the input queue by waiting the response to come
into the same input queue.
Instead allow sending Modem Status Command without waiting for remote
end to respond. Define a new function gsm_modem_send_initial_msc()
for this purpose. As MSC is only valid for basic encoding, it does
not do anything for advanced or when convergence layer type 2 is used.

Summary
In the Linux kernel, the following vulnerability has been resolved:
phy: ralink: mt7621-pci: add sentinel to quirks table
With mt7621 soc_dev_attr fixed to register the soc as a device,
kernel will experience an oops in soc_device_match_attr
This quirk test was introduced in the staging driver in
commit 9445ccb3714c ("staging: mt7621-pci-phy: add quirks for 'E2'
revision using 'soc_device_attribute'"). The staging driver was removed,
and later re-added in commit d87da32372a0 ("phy: ralink: Add PHY driver
for MT7621 PCIe PHY") for kernel 5.11

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/meson: Fix refcount bugs in meson_vpu_has_available_connectors()
In this function, there are two refcount leak bugs:
(1) when breaking out of for_each_endpoint_of_node(), we need call
the of_node_put() for the 'ep';
(2) we should call of_node_put() for the reference returned by
of_graph_get_remote_port() when it is not used anymore.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau/nvif: Fix potential memory leak in nvif_vmm_ctor().
When the nvif_vmm_type is invalid, we will return error directly
without freeing the args in nvif_vmm_ctor(), which leading a memory
leak. Fix it by setting the ret -EINVAL and goto done.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Check kzalloc() in lpfc_sli4_cgn_params_read()
If kzalloc() fails in lpfc_sli4_cgn_params_read(), then we rely on
lpfc_read_object()'s routine to NULL check pdata.
Currently, an early return error is thrown from lpfc_read_object() to
protect us from NULL ptr dereference, but the errno code is -ENODEV.
Change the errno code to a more appropriate -ENOMEM.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Acquire SRCU in KVM_GET_MP_STATE to protect guest memory accesses
Acquire a lock on kvm->srcu when userspace is getting MP state to handle a
rather extreme edge case where "accepting" APIC events, i.e. processing
pending INIT or SIPI, can trigger accesses to guest memory. If the vCPU
is in L2 with INIT *and* a TRIPLE_FAULT request pending, then getting MP
state will trigger a nested VM-Exit by way of ->check_nested_events(), and
emuating the nested VM-Exit can access guest memory.
The splat was originally hit by syzkaller on a Google-internal kernel, and
reproduced on an upstream kernel by hacking the triple_fault_event_test
selftest to stuff a pending INIT, store an MSR on VM-Exit (to generate a
memory access on VMX), and do vcpu_mp_state_get() to trigger the scenario.

Summary
In the Linux kernel, the following vulnerability has been resolved:
udf: Fix uninitialized array access for some pathnames
For filenames that begin with . and are between 2 and 5 characters long,
UDF charset conversion code would read uninitialized memory in the
output buffer. The only practical impact is that the name may be prepended a
"unification hash" when it is not actually needed but still it is good
to fix this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Revert "usb: typec: ucsi: add a common function ucsi_unregister_connectors()"
The recent commit 87d0e2f41b8c ("usb: typec: ucsi: add a common
function ucsi_unregister_connectors()") introduced a regression that
caused NULL dereference at reading the power supply sysfs. It's a
stale sysfs entry that should have been removed but remains with NULL
ops. The commit changed the error handling to skip the entries after
a NULL con->wq, and this leaves the power device unreleased.
For addressing the regression, the straight revert is applied here.
Further code improvements can be done from the scratch again.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ath9k: fix use-after-free in ath9k_hif_usb_rx_cb
Syzbot reported use-after-free Read in ath9k_hif_usb_rx_cb() [0]. The
problem was in incorrect htc_handle->drv_priv initialization.
Probable call trace which can trigger use-after-free:
ath9k_htc_probe_device()
/* htc_handle->drv_priv = priv; */
ath9k_htc_wait_for_target() <--- Failed
ieee80211_free_hw() <--- priv pointer is freed
<IRQ>
...
ath9k_hif_usb_rx_cb()
ath9k_hif_usb_rx_stream()
RX_STAT_INC() <--- htc_handle->drv_priv access
In order to not add fancy protection for drv_priv we can move
htc_handle->drv_priv initialization at the end of the
ath9k_htc_probe_device() and add helper macro to make
all *_STAT_* macros NULL safe, since syzbot has reported related NULL
deref in that macros [1]

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: ti: edma: Fix memory allocation size for queue_priority_map
Fix a critical memory allocation bug in edma_setup_from_hw() where
queue_priority_map was allocated with insufficient memory. The code
declared queue_priority_map as s8 (*)[2] (pointer to array of 2 s8),
but allocated memory using sizeof(s8) instead of the correct size.
This caused out-of-bounds memory writes when accessing:
queue_priority_map[i][0] = i;
queue_priority_map[i][1] = i;
The bug manifested as kernel crashes with "Oops - undefined instruction"
on ARM platforms (BeagleBoard-X15) during EDMA driver probe, as the
memory corruption triggered kernel hardening features on Clang.
Change the allocation to use sizeof(*queue_priority_map) which
automatically gets the correct size for the 2D array structure.

No network, adjacent-network, or remote-peer data reaches the path, and Local is the higher-severity of the two plausible readings versus Physical (DTB/board substitution).\nAC:L - The size error is unconditional \u2014 `sizeof(s8)` is always half of `sizeof(s8[2])`, so the buffer is always half the needed length, and no in-tree platform_data supplies `queue_priority_mapping` to take the early return. The overflow fires deterministically on every boot of every affected TI SoC with no race to win and no memory-layout precondition, and was reported as a reproducible probe-time Oops on BeagleBoard-X15.\nPR:N - No credential, capability, or namespace check exists anywhere on the path \u2014 the heap is corrupted by the kernel\u0027s own device-tree probe machinery during boot, before any user session exists, so the vulnerable state is reached with zero privileges. Deliberate re-triggering via sysfs bind/unbind or `rmmod`/`insmod` would need root, but that is not required for the corruption to arise (same basis as CVE-2025-39882 and CVE-2025-39930).\nUI:N - The EDMA platform driver binds automatically from the device tree during kernel boot and deferred-probe retries run unattended; `edma_pm_resume()` likewise runs on every system resume. No administrator or victim action, mount, file open, or device insertion is needed.\nS:U - The overflowed slab object, the adjacent kernel heap, and the EDMA MMIO window all belong to the kernel\u0027s own security authority, and the faulting code executes in that same kernel context. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The `-1` terminator is itself written out of bounds, so once an intervening `devm_kcalloc()` in `edma_probe()` reclaims or zeroes that byte, `for (i = 0; queue_priority_mapping[i][0] != -1; i++)` walks kernel heap without bound, reading arbitrary adjacent slab contents and pushing them into the EDMA `QUEPRI` register \u2014 an unbounded out-of-bounds read with an observable exfiltration channel, and the resulting hardened-kernel splat leaks kernel pointers and a full stack trace.\nI:H - This is a slab out-of-bounds write past a `devm_kcalloc()` allocation, corrupting adjacent heap contents (including device-tree-supplied `ti,tptcs` priority values written through the undersized buffer at `edma_probe():2474`), and out-of-bounds heap writes of this class are the classic basis for heap-grooming-based write primitives. The follow-on `edma_assign_priority_to_queue()` shift-by-up-to-508 further writes heap-derived garbage into hardware registers, corrupting DMA-engine queue arbitration for all downstream consumers.\nA:H - The overflow was reported to crash the kernel outright with \"Oops - undefined instruction\" during EDMA probe on BeagleBoard-X15 under Clang hardening, and the unterminated consumer loop can spin over the heap issuing MMIO writes. On these boards EDMA is required for MMC, SPI, audio and network DMA, so a probe-time panic or corrupted queue configuration renders the system unbootable or unusable, and `edma_pm_resume()` reproduces it on every resume."

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: imx: scu: use _safe list iterator to avoid a use after free
This loop is freeing "clk" so it needs to use list_for_each_entry_safe().
Otherwise it dereferences a freed variable to get the next item on the
loop.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ring-buffer: Do not swap cpu_buffer during resize process
When ring_buffer_swap_cpu was called during resize process,
the cpu buffer was swapped in the middle, resulting in incorrect state.
Continuing to run in the wrong state will result in oops.
This issue can be easily reproduced using the following two scripts:
/tmp # cat test1.sh
//#! /bin/sh
for i in `seq 0 100000`
do
echo 2000 > /sys/kernel/debug/tracing/buffer_size_kb
sleep 0.5
echo 5000 > /sys/kernel/debug/tracing/buffer_size_kb
sleep 0.5
done
/tmp # cat test2.sh
//#! /bin/sh
for i in `seq 0 100000`
do
echo irqsoff > /sys/kernel/debug/tracing/current_tracer
sleep 1
echo nop > /sys/kernel/debug/tracing/current_tracer
sleep 1
done
/tmp # ./test1.sh &
/tmp # ./test2.sh &
A typical oops log is as follows, sometimes with other different oops logs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: xsk: prohibit usage of non-balanced queue id
Fix the following scenario:
1. ethtool -L $IFACE rx 8 tx 96
2. xdpsock -q 10 -t -z
Above refers to a case where user would like to attach XSK socket in
txonly mode at a queue id that does not have a corresponding Rx queue.
At this moment ice's XSK logic is tightly bound to act on a "queue pair",
e.g. both Tx and Rx queues at a given queue id are disabled/enabled and
both of them will get XSK pool assigned, which is broken for the presented
queue configuration. This results in the splat included at the bottom,
which is basically an OOB access to Rx ring array.
To fix this, allow using the ids only in scope of "combined" queues
reported by ethtool. However, logic should be rewritten to allow such
configurations later on, which would end up as a complete rewrite of the
control path, so let us go with this temporary fix.

This results in the splat included at the bottom,\nwhich is basically an OOB access to Rx ring array.\n\nTo fix this, allow using the ids only in scope of \"combined\" queues\nreported by ethtool. However, logic should be rewritten to allow such\nconfigurations later on, which would end up as a complete rewrite of the\ncontrol path, so let us go with this temporary fix.\n\n[420160.558008] BUG: kernel NULL pointer dereference, address: 0000000000000082\n[420160.566359] #PF: supervisor read access in kernel mode\n[420160.572657] #PF: error_code(0x0000) - not-present page\n[420160.579002] PGD 0 P4D 0\n[420160.582756] Oops: 0000 [#1] PREEMPT SMP NOPTI\n[420160.588396] CPU: 10 PID: 21232 Comm: xdpsock Tainted: G OE 5.19.0-rc7+ #10\n[420160.597893] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0008.031920191559 03/19/2019\n[420160.609894] RIP: 0010:ice_xsk_pool_setup+0x44/0x7d0 [ice]\n[420160.616968] Code: f3 48 83 ec 40 48 8b 4f 20 48 8b 3f 65 48 8b 04 25 28 00 00 00 48 89 44 24 38 31 c0 48 8d 04 ed 00 00 00 00 48 01 c1 48 8b 11 \u003c0f\u003e b7 92 82 00 00 00 48 85 d2 0f 84 2d 75 00 00 48 8d 72 ff 48 85\n[420160.639421] RSP: 0018:ffffc9002d2afd48 EFLAGS: 00010282\n[420160.646650] RAX: 0000000000000050 RBX: ffff88811d8bdd00 RCX: ffff888112c14ff8\n[420160.655893] RDX: 0000000000000000 RSI: ffff88811d8bdd00 RDI: ffff888109861000\n[420160.665166] RBP: 000000000000000a R08: 000000000000000a R09: 0000000000000000\n[420160.674493] R10: 000000000000889f R11: 0000000000000000 R12: 000000000000000a\n[420160.683833] R13: 000000000000000a R14: 0000000000000000 R15: ffff888117611828\n[420160.693211] FS: 00007fa869fc1f80(0000) GS:ffff8897e0880000(0000) knlGS:0000000000000000\n[420160.703645] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[420160.711783] CR2: 0000000000000082 CR3: 00000001d076c001 CR4: 00000000007706e0\n[420160.721399] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n[420160.731045] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n[420160.740707] PKRU: 55555554\n[420160.745960] Call Trace:\n[420160.750962] \u003cTASK\u003e\n[420160.755597] ? kmalloc_large_node+0x79/0x90\n[420160.762703] ? __kmalloc_node+0x3f5/0x4b0\n[420160.769341] xp_assign_dev+0xfd/0x210\n[420160.775661] ? shmem_file_read_iter+0x29a/0x420\n[420160.782896] xsk_bind+0x152/0x490\n[420160.788943] __sys_bind+0xd0/0x100\n[420160.795097] ? exit_to_user_mode_prepare+0x20/0x120\n[420160.802801] __x64_sys_bind+0x16/0x20\n[420160.809298] do_syscall_64+0x38/0x90\n[420160.815741] entry_SYSCALL_64_after_hwframe+0x63/0xcd\n[420160.823731] RIP: 0033:0x7fa86a0dd2fb\n[420160.830264] Code: c3 66 0f 1f 44 00 00 48 8b 15 69 8b 0c 00 f7 d8 64 89 02 b8 ff ff ff ff eb bc 0f 1f 44 00 00 f3 0f 1e fa b8 31 00 00 00 0f 05 \u003c48\u003e 3d 01 f0 ff ff 73 01 c3 48 8b 0d 3d 8b 0c 00 f7 d8 64 89 01 48\n[420160.855410] RSP: 002b:00007ffc1146f618 EFLAGS: 00000246 ORIG_RAX: 0000000000000031\n[420160.866366] RAX: ffffffffffffffda RBX: 0000000000000000 RCX: 00007fa86a0dd2fb\n[420160.876957] RDX: 0000000000000010 RSI: 00007ffc1146f680 RDI: 0000000000000003\n[420160.887604] RBP: 000055d7113a0520 R08: 00007fa868fb8000 R09: 0000000080000000\n[420160.898293] R10: 0000000000008001 R11: 0000000000000246 R12: 000055d7113a04e0\n[420160.909038] R13: 000055d7113a0320 R14: 000000000000000a R15: 0000000000000000\n[420160.919817] \u003c/TASK\u003e\n[420160.925659] Modules linked in: ice(OE) af_packet binfmt_misc\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: Disallow dirty tracking if incoherent page walk
Dirty page tracking relies on the IOMMU atomically updating the dirty bit
in the paging-structure entry. For this operation to succeed, the paging-
structure memory must be coherent between the IOMMU and the CPU. In
another word, if the iommu page walk is incoherent, dirty page tracking
doesn't work.
The Intel VT-d specification, Section 3.10 "Snoop Behavior" states:
"Remapping hardware encountering the need to atomically update A/EA/D bits
in a paging-structure entry that is not snooped will result in a non-
recoverable fault."
To prevent an IOMMU from being incorrectly configured for dirty page
tracking when it is operating in an incoherent mode, mark SSADS as
supported only when both ecap_slads and ecap_smpwc are supported.

A compromised VMM process or a user in a device-assignment group can drive the entire sequence.\nUI:N - The full sequence \u2014 hwpt allocation, dirty-tracking enable, and the subsequent device DMA \u2014 is driven entirely by the attacker\u0027s own process and the device it already controls. No victim action is needed.\nS:C - The defect is in the IOMMU\u0027s own DMA-isolation enforcement: SSADE is programmed on hardware that cannot coherently update paging-structure entries, and the unflushed cached RMW in intel_iommu_read_and_clear_dirty() can resurrect stale second-stage PTEs. An assigned device\u0027s DMA then reaches memory outside its authorized translation, crossing the IOMMU security boundary.\nC:H - Stale or incorrectly-updated second-stage paging entries leave a device-visible mapping to host pages that have been unmapped and potentially reassigned, giving the controlled device DMA reads of arbitrary host memory. Dirty-bitmap results are also unreliable, leaking incorrect state across a migration boundary.\nI:H - The same stale-translation window gives the assigned device DMA writes into host memory outside its mapping \u2014 an arbitrary write primitive from the device side that defeats IOMMU containment. Silently missed dirty pages additionally corrupt guest memory state on live migration.\nA:H - The VT-d specification mandates a non-recoverable fault whenever the hardware must atomically update A/EA/D bits in a non-snooped paging-structure entry, so the assigned device\u0027s DMA is blocked outright and the DMAR fault handler is driven repeatedly. The device and any VM depending on it are rendered inoperable."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: libiscsi: Initialize iscsi_conn->dd_data only if memory is allocated
In case of an ib_fast_reg_mr allocation failure during iSER setup, the
machine hits a panic because iscsi_conn->dd_data is initialized
unconditionally, even when no memory is allocated (dd_size == 0). This
leads invalid pointer dereference during connection teardown.
Fix by setting iscsi_conn->dd_data only if memory is actually allocated.
Panic trace:
------------
iser: iser_create_fastreg_desc: Failed to allocate ib_fast_reg_mr err=-12
iser: iser_alloc_rx_descriptors: failed allocating rx descriptors / data buffers
BUG: unable to handle page fault for address: fffffffffffffff8

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix use-after-free of nilfs_root in dirtying inodes via iput
During unmount process of nilfs2, nothing holds nilfs_root structure after
nilfs2 detaches its writer in nilfs_detach_log_writer(). Previously,
nilfs_evict_inode() could cause use-after-free read for nilfs_root if
inodes are left in "garbage_list" and released by nilfs_dispose_list at
the end of nilfs_detach_log_writer(), and this bug was fixed by commit
9b5a04ac3ad9 ("nilfs2: fix use-after-free bug of nilfs_root in
nilfs_evict_inode()").
However, it turned out that there is another possibility of UAF in the
call path where mark_inode_dirty_sync() is called from iput():
nilfs_detach_log_writer()
nilfs_dispose_list()
iput()
mark_inode_dirty_sync()
__mark_inode_dirty()
nilfs_dirty_inode()
__nilfs_mark_inode_dirty()
nilfs_load_inode_block() --> causes UAF of nilfs_root struct
This can happen after commit 0ae45f63d4ef ("vfs: add support for a
lazytime mount option"), which changed iput() to call
mark_inode_dirty_sync() on its final reference if i_state has I_DIRTY_TIME
flag and i_nlink is non-zero.
This issue appears after commit 28a65b49eb53 ("nilfs2: do not write dirty
data after degenerating to read-only") when using the syzbot reproducer,
but the issue has potentially existed before.
Fix this issue by adding a "purging flag" to the nilfs structure, setting
that flag while disposing the "garbage_list" and checking it in
__nilfs_mark_inode_dirty().
Unlike commit 9b5a04ac3ad9 ("nilfs2: fix use-after-free bug of nilfs_root
in nilfs_evict_inode()"), this patch does not rely on ns_writer to
determine whether to skip operations, so as not to break recovery on
mount. The nilfs_salvage_orphan_logs routine dirties the buffer of
salvaged data before attaching the log writer, so changing
__nilfs_mark_inode_dirty() to skip the operation when ns_writer is NULL
will cause recovery write to fail. The purpose of using the cleanup-only
flag is to allow for narrowing of such conditions.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powercap: arm_scmi: Remove recursion while parsing zones
Powercap zones can be defined as arranged in a hierarchy of trees and when
registering a zone with powercap_register_zone(), the kernel powercap
subsystem expects this to happen starting from the root zones down to the
leaves; on the other side, de-registration by powercap_deregister_zone()
must begin from the leaf zones.
Available SCMI powercap zones are retrieved dynamically from the platform
at probe time and, while any defined hierarchy between the zones is
described properly in the zones descriptor, the platform returns the
availables zones with no particular well-defined order: as a consequence,
the trees possibly composing the hierarchy of zones have to be somehow
walked properly to register the retrieved zones from the root.
Currently the ARM SCMI Powercap driver walks the zones using a recursive
algorithm; this approach, even though correct and tested can lead to kernel
stack overflow when processing a returned hierarchy of zones composed by
particularly high trees.
Avoid possible kernel stack overflow by substituting the recursive approach
with an iterative one supported by a dynamically allocated stack-like data
structure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA: hfi1: fix possible divide-by-zero in find_hw_thread_mask()
The function divides number of online CPUs by num_core_siblings, and
later checks the divider by zero. This implies a possibility to get
and divide-by-zero runtime error. Fix it by moving the check prior to
division. This also helps to save one indentation level.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: core: Fix a procfs host directory removal regression
scsi_proc_hostdir_rm() decreases a reference counter and hence must only be
called once per host that is removed. This change does not require a
scsi_add_host_with_dma() change since scsi_add_host_with_dma() will return
0 (success) if scsi_proc_host_add() is called.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cxl/acpi: Fix a use-after-free in cxl_parse_cfmws()
KASAN and KFENCE detected an user-after-free in the CXL driver. This
happens in the cxl_decoder_add() fail path. KASAN prints the following
error:
BUG: KASAN: slab-use-after-free in cxl_parse_cfmws (drivers/cxl/acpi.c:299)
This happens in cxl_parse_cfmws(), where put_device() is called,
releasing cxld, which is accessed later.
Use the local variables in the dev_err() instead of pointing to the
released memory. Since the dev_err() is printing a resource, change the open
coded print format to use the %pr format specifier.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Don't use tnum_range on array range checking for poke descriptors
Hsin-Wei reported a KASAN splat triggered by their BPF runtime fuzzer which
is based on a customized syzkaller:

RIP: 0033:0x7f917c4e2c2d
The problem here is that a range of tnum_range(0, map->max_entries - 1) has
limited ability to represent the concrete tight range with the tnum as the
set of resulting states from value + mask can result in a superset of the
actual intended range, and as such a tnum_in(range, reg->var_off) check may
yield true when it shouldn't, for example tnum_range(0, 2) would result in
00XX -> v = 0000, m = 0011 such that the intended set of {0, 1, 2} is here
represented by a less precise superset of {0, 1, 2, 3}. As the register is
known const scalar, really just use the concrete reg->var_off.value for the
upper index check.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ixgbevf: fix mailbox API compatibility by negotiating supported features
There was backward compatibility in the terms of mailbox API. Various
drivers from various OSes supporting 10G adapters from Intel portfolio
could easily negotiate mailbox API.
This convention has been broken since introducing API 1.4.
Commit 0062e7cc955e ("ixgbevf: add VF IPsec offload code") added support
for IPSec which is specific only for the kernel ixgbe driver. None of the
rest of the Intel 10G PF/VF drivers supports it. And actually lack of
support was not included in the IPSec implementation - there were no such
code paths. No possibility to negotiate support for the feature was
introduced along with introduction of the feature itself.
Commit 339f28964147 ("ixgbevf: Add support for new mailbox communication
between PF and VF") increasing API version to 1.5 did the same - it
introduced code supported specifically by the PF ESX driver. It altered API
version for the VF driver in the same time not touching the version
defined for the PF ixgbe driver. It led to additional discrepancies,
as the code provided within API 1.6 cannot be supported for Linux ixgbe
driver as it causes crashes.
The issue was noticed some time ago and mitigated by Jake within the commit
d0725312adf5 ("ixgbevf: stop attempting IPSEC offload on Mailbox API 1.5").
As a result we have regression for IPsec support and after increasing API
to version 1.6 ixgbevf driver stopped to support ESX MBX.
To fix this mess add new mailbox op asking PF driver about supported
features. Basing on a response determine whether to set support for IPSec
and ESX-specific enhanced mailbox.
New mailbox op, for compatibility purposes, must be added within new API
revision, as API version of OOT PF & VF drivers is already increased to
1.6 and doesn't incorporate features negotiate op.
Features negotiation mechanism gives possibility to be extended with new
features when needed in the future.

No possibility to negotiate support for the feature was\nintroduced along with introduction of the feature itself.\n\nCommit 339f28964147 (\"ixgbevf: Add support for new mailbox communication\nbetween PF and VF\") increasing API version to 1.5 did the same - it\nintroduced code supported specifically by the PF ESX driver. It altered API\nversion for the VF driver in the same time not touching the version\ndefined for the PF ixgbe driver. It led to additional discrepancies,\nas the code provided within API 1.6 cannot be supported for Linux ixgbe\ndriver as it causes crashes.\n\nThe issue was noticed some time ago and mitigated by Jake within the commit\nd0725312adf5 (\"ixgbevf: stop attempting IPSEC offload on Mailbox API 1.5\").\nAs a result we have regression for IPsec support and after increasing API\nto version 1.6 ixgbevf driver stopped to support ESX MBX.\n\nTo fix this mess add new mailbox op asking PF driver about supported\nfeatures. Basing on a response determine whether to set support for IPSec\nand ESX-specific enhanced mailbox.\n\nNew mailbox op, for compatibility purposes, must be added within new API\nrevision, as API version of OOT PF \u0026 VF drivers is already increased to\n1.6 and doesn\u0027t incorporate features negotiate op.\n\nFeatures negotiation mechanism gives possibility to be extended with new\nfeatures when needed in the future."

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: hv: Fix a crash in hv_pci_restore_msi_msg() during hibernation
When a Linux VM with an assigned PCI device runs on Hyper-V, if the PCI
device driver is not loaded yet (i.e. MSI-X/MSI is not enabled on the
device yet), doing a VM hibernation triggers a panic in
hv_pci_restore_msi_msg() -> msi_lock_descs(&pdev->dev), because
pdev->dev.msi.data is still NULL.
Avoid the panic by checking if MSI-X/MSI is enabled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: pvrusb2: fix memory leak in pvr_probe
The error handling code in pvr2_hdw_create forgets to unregister the
v4l2 device. When pvr2_hdw_create returns back to pvr2_context_create,
it calls pvr2_context_destroy to destroy context, but mp->hdw is NULL,
which leads to that pvr2_hdw_destroy directly returns.
Fix this by adding v4l2_device_unregister to decrease the refcount of
usb interface.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: do not ignore genmask when looking up chain by id
When adding a rule to a chain referring to its ID, if that chain had been
deleted on the same batch, the rule might end up referring to a deleted
chain.
This will lead to a WARNING like following:

This is due to the nft_chain_lookup_byid ignoring the genmask. After this
change, adding the new rule will fail as it will not find the chain.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/hisilicon/hibmc: fix the hibmc loaded failed bug
When hibmc loaded failed, the driver use hibmc_unload to free the
resource, but the mutexes in mode.config are not init, which will
access an NULL pointer. Just change goto statement to return, because
hibnc_hw_init() doesn't need to free anything.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ntfs: check overflow when iterating ATTR_RECORDs
Kernel iterates over ATTR_RECORDs in mft record in ntfs_attr_find().
Because the ATTR_RECORDs are next to each other, kernel can get the next
ATTR_RECORD from end address of current ATTR_RECORD, through current
ATTR_RECORD length field.
The problem is that during iteration, when kernel calculates the end
address of current ATTR_RECORD, kernel may trigger an integer overflow bug
in executing `a = (ATTR_RECORD*)((u8*)a + le32_to_cpu(a->length))`. This
may wrap, leading to a forever iteration on 32bit systems.
This patch solves it by adding some checks on calculating end address
of current ATTR_RECORD during iteration.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dp: Free resources after unregistering them
The DP component's unbind operation walks through the submodules to
unregister and clean things up. But if the unbind happens because the DP
controller itself is being removed, all the memory for those submodules
has just been freed.
Change the order of these operations to avoid the many use-after-free
that otherwise happens in this code path.

"value": "AV:L - The malicious input arrives as a `VIRTCHNL_OP_CONFIG_VSI_QUEUES` message on the SR-IOV VF\u2192PF admin-queue mailbox, a PCIe transport, not a network protocol. The attacker needs local control of an assigned VF (guest VM or VF-owning container), so this is local reachability rather than network or adjacent.\nAC:L - The attacker fully controls every input \u2014 `num_tc` and per-TC `count` via ENABLE_CHANNELS, then `num_queue_pairs` and the qpair array via CONFIG_VSI_QUEUES \u2014 so shrinking `num_tc` to leave stale `ch[]` entries and then walking `idx` into them is deterministic on the first attempt with no memory grooming or race. The only precondition, spoofchk disabled, is inherent to any ADq-enabled SR-IOV deployment and is a standard runtime configuration.\nPR:L - The attacker only needs to drive the VF\u0027s admin queue \u2014 kernel/root inside the assigned guest, or possession of the VFIO device \u2014 which is a low-privileged position relative to the host PF driver under attack. No privileges of any kind on the host are required.\nUI:N - The malicious VF sends the virtchnl message sequence entirely on its own initiative. No host administrator or other user action is needed at any stage.\nS:C - The attacking VF sits in a guest VM (or VF-assigned container) while the stale-index read and the resulting hardware queue-context programming occur in the host PF driver\u0027s security authority. The corrupted resources \u2014 HMC LAN Tx/Rx contexts and QTX_CTL bindings of VSIs belonging to the PF or to other VFs \u2014 are outside the attacker\u0027s scope, crossing the guest/host and inter-tenant SR-IOV boundary.\nC:H - Using a stale `ch[idx].vsi_id`, the VF resolves and reprograms the Rx queue context of a VSI it does not own, setting `rx_ctx.base` from its own `dma_ring_addr` so another VSI\u0027s received traffic is DMA\u0027d into attacker-designated memory \u2014 interception of host and cross-guest traffic. On pre-5.2 kernels the same defect additionally reads past the end of `vf-\u003ech[]` into adjacent `struct i40e_vf` state.\nI:H - `i40e_config_vsi_rx_queue()` performs no ownership check and `i40e_config_vsi_tx_queue()` validates only the VF-supplied `info-\u003evsi_id`, so the stale ID lets the VF clear and rewrite the LAN HMC Tx/Rx contexts of a foreign VSI\u0027s queues and issue a `QTX_CTL` write rebinding that PF queue to itself. This is attacker-controlled modification of host- and peer-owned hardware state.\nA:H - Clearing and rewriting queue contexts belonging to the PF\u0027s main VSI or another guest\u0027s VSI stalls or wedges those queues, and out-of-range `pf_queue_id` values (`I40E_QUEUE_END_OF_LIST`) drive HMC operations that trigger adapter error paths, PF/VF reset storms and loss of host networking. The VF can repeat the sequence at will, and a downed host PF takes every guest on the adapter with it."

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: venus: protect against spurious interrupts during probe
Make sure the interrupt handler is initialized before the interrupt is
registered.
If the IRQ is registered before hfi_create(), it's possible that an
interrupt fires before the handler setup is complete, leading to a NULL
dereference.
This error condition has been observed during system boot on Rb3Gen2.

Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix crypto buffers in non-linear memory
The crypto API, through the scatterlist API, expects input buffers to be
in linear memory. We handle this with the cifs_sg_set_buf() helper
that converts vmalloc'd memory to their corresponding pages.
However, when we allocate our aead_request buffer (@creq in
smb2ops.c::crypt_message()), we do so with kvzalloc(), which possibly
puts aead_request->__ctx in vmalloc area.
AEAD algorithm then uses ->__ctx for its private/internal data and
operations, and uses sg_set_buf() for such data on a few places.
This works fine as long as @creq falls into kmalloc zone (small
requests) or vmalloc'd memory is still within linear range.
Tasks' stacks are vmalloc'd by default (CONFIG_VMAP_STACK=y), so too
many tasks will increment the base stacks' addresses to a point where
virt_addr_valid(buf) will fail (BUG() in sg_set_buf()) when that
happens.
In practice: too many parallel reads and writes on an encrypted mount
will trigger this bug.
To fix this, always alloc @creq with kmalloc() instead.
Also drop the @sensitive_size variable/arguments since
kfree_sensitive() doesn't need it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211_hwsim: drop short frames
While technically some control frames like ACK are shorter and
end after Address 1, such frames shouldn't be forwarded through
wmediumd or similar userspace, so require the full 3-address
header to avoid accessing invalid memory if shorter frames are
passed in.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: fix potential buffer overflow in do_register_framebuffer()
The current implementation may lead to buffer overflow when:
1. Unregistration creates NULL gaps in registered_fb[]
2. All array slots become occupied despite num_registered_fb < FB_MAX
3. The registration loop exceeds array bounds
Add boundary check to prevent registered_fb[FB_MAX] access.

ASoC: qcom: q6apm-lpass-dais: Fix NULL pointer dereference if source graph failed
If earlier opening of source graph fails (e.g. ADSP rejects due to
incorrect audioreach topology), the graph is closed and
"dai_data->graph[dai->id]" is assigned NULL. Preparing the DAI for sink
graph continues though and next call to q6apm_lpass_dai_prepare()
receives dai_data->graph[dai->id]=NULL leading to NULL pointer
exception:
qcom-apm gprsvc:service:2:1: Error (1) Processing 0x01001002 cmd

Summary
In the Linux kernel, the following vulnerability has been resolved:
ath11k: fix missing skb drop on htc_tx_completion error
On htc_tx_completion error the skb is not dropped. This is wrong since
the completion_handler logic expect the skb to be consumed anyway even
when an error is triggered. Not freeing the skb on error is a memory
leak since the skb won't be freed anywere else. Correctly free the
packet on eid >= ATH11K_HTC_EP_COUNT before returning.
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.5.0.1-01208-QCAHKSWPL_SILICONZ-1

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: Refactor remove call with idxd_cleanup() helper
The idxd_cleanup() helper cleans up perfmon, interrupts, internals and
so on. Refactor remove call with the idxd_cleanup() helper to avoid code
duplication. Note, this also fixes the missing put_device() for idxd
groups, enginces and wqs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/tdx: Panic on bad configs that #VE on "private" memory access
All normal kernel memory is "TDX private memory". This includes
everything from kernel stacks to kernel text. Handling
exceptions on arbitrary accesses to kernel memory is essentially
impossible because they can happen in horribly nasty places like
kernel entry/exit. But, TDX hardware can theoretically _deliver_
a virtualization exception (#VE) on any access to private memory.
But, it's not as bad as it sounds. TDX can be configured to never
deliver these exceptions on private memory with a "TD attribute"
called ATTR_SEPT_VE_DISABLE. The guest has no way to *set* this
attribute, but it can check it.
Ensure ATTR_SEPT_VE_DISABLE is set in early boot. panic() if it
is unset. There is no sane way for Linux to run with this
attribute clear so a panic() is appropriate.
There's small window during boot before the check where kernel
has an early #VE handler. But the handler is only for port I/O
and will also panic() as soon as it sees any other #VE, such as
a one generated by a private memory access.
[ dhansen: Rewrite changelog and rebase on new tdx_parse_tdinfo().
Add Kirill's tested-by because I made changes since
he wrote this. ]

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: PPTT: Fix to avoid sleep in the atomic context when PPTT is absent
Commit 0c80f9e165f8 ("ACPI: PPTT: Leave the table mapped for the runtime usage")
enabled to map PPTT once on the first invocation of acpi_get_pptt() and
never unmapped the same allowing it to be used at runtime with out the
hassle of mapping and unmapping the table. This was needed to fetch LLC
information from the PPTT in the cpuhotplug path which is executed in
the atomic context as the acpi_get_table() might sleep waiting for a
mutex.
However it missed to handle the case when there is no PPTT on the system
which results in acpi_get_pptt() being called from all the secondary
CPUs attempting to fetch the LLC information in the atomic context
without knowing the absence of PPTT resulting in the splat like below:
| BUG: sleeping function called from invalid context at kernel/locking/semaphore.c:164

Update acpi_get_pptt() to consider the fact that PPTT is once checked and
is not available on the system and return NULL avoiding any attempts to
fetch PPTT and thereby avoiding any possible sleep waiting for a mutex
in the atomic context.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: do not run mt76_unregister_device() on unregistered hw
Trying to probe a mt7921e pci card without firmware results in a
successful probe where ieee80211_register_hw hasn't been called. When
removing the driver, ieee802111_unregister_hw is called unconditionally
leading to a kernel NULL pointer dereference.
Fix the issue running mt76_unregister_device routine just for registered
hw.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers:md:fix a potential use-after-free bug
In line 2884, "raid5_release_stripe(sh);" drops the reference to sh and
may cause sh to be released. However, sh is subsequently used in lines
2886 "if (sh->batch_head && sh != sh->batch_head)". This may result in an
use-after-free bug.
It can be fixed by moving "raid5_release_stripe(sh);" to the bottom of
the function.

SRv6 packets are not link-local, so an attacker anywhere on the network can drive the oracle.\nAC:L - The attacker controls both sides of the measurement \u2014 the candidate MAC bytes and an unlimited, self-paced stream of probe packets \u2014 so the byte-at-a-time `memcmp` leak can be amplified by repetition and statistical averaging, including jitter-immune concurrent-probe techniques. No condition depends on state the attacker cannot influence.\nPR:N - The HMAC validation is itself the authentication gate for the SR domain; nothing on the path from packet receive to `seg6_hmac_validate_skb()` checks any credential or capability. The attacker is an unauthenticated off-path/off-domain sender.\nUI:N - Exploitation requires only sending crafted SRv6 packets to the target; no victim action is involved.\nS:U - The forged authentication is consumed and acted upon within the same kernel networking authority that performs the check; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Forging the SRH MAC bypasses the SR-domain trust boundary, letting the attacker source-route packets to otherwise unreachable internal nodes and, via End.DT4/DT6/DX behaviors, into isolated tenant VRFs and L2 domains, with the return path steerable back to the attacker. The timing oracle additionally recovers secret-key-derived MAC values.\nI:H - A recovered MAC makes the kernel accept attacker-crafted segment lists as authentic, allowing arbitrary rewriting of forwarding paths and injection of spoofed traffic into tenant networks and internal L2 bridges \u2014 a complete authentication bypass of the SRv6 integrity mechanism.\nA:H - Forged segment lists can be built to loop packets repeatedly between SR nodes and to blackhole or misdirect legitimate traffic, disrupting forwarding for the node and the SR domain it serves."

In the Linux kernel, the following vulnerability has been resolved:
USB: core: Prevent nested device-reset calls
Automatic kernel fuzzing revealed a recursive locking violation in

This turned out not to be an error in usb-storage but rather a nested
device reset attempt. That is, as the rtl8712 driver was being
unbound from a composite device in preparation for an unrelated USB
reset (that driver does not have pre_reset or post_reset callbacks),
its ->remove routine called usb_reset_device() -- thus nesting one
reset call within another.
Performing a reset as part of disconnect processing is a questionable
practice at best. However, the bug report points out that the USB
core does not have any protection against nested resets. Adding a
reset_in_progress flag and testing it will prevent such errors in the
future.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/fb-helper: Fix out-of-bounds access
Clip memory range to screen-buffer size to avoid out-of-bounds access
in fbdev deferred I/O's damage handling.
Fbdev's deferred I/O can only track pages. From the range of pages, the
damage handler computes the clipping rectangle for the display update.
If the fbdev screen buffer ends near the beginning of a page, that page
could contain more scanlines. The damage handler would then track these
non-existing scanlines as dirty and provoke an out-of-bounds access
during the screen update. Hence, clip the maximum memory range to the
size of the screen buffer.
While at it, rename the variables min/max to min_off/max_off in
drm_fb_helper_deferred_io(). This avoids confusion with the macros of
the same name.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Fix handling of lrbp->cmd
ufshcd_queuecommand() may be called two times in a row for a SCSI command
before it is completed. Hence make the following changes:
- In the functions that submit a command, do not check the old value of
lrbp->cmd nor clear lrbp->cmd in error paths.
- In ufshcd_release_scsi_cmd(), do not clear lrbp->cmd.
See also scsi_send_eh_cmnd().
This commit prevents that the following appears if a command times out:
WARNING: at drivers/ufs/core/ufshcd.c:2965 ufshcd_queuecommand+0x6f8/0x9a8

"value": "AV:L - The affected code is the UFS host controller core driver, reached by submitting SCSI commands to local storage (filesystem I/O, SG_IO on the block device, or /dev/ufs-bsg) and by the kernel SCSI error handler that runs on top of them. There is no network or adjacent-network exposure, and no physical device attachment is needed since UFS is internal soldered storage.\nAC:L - A local attacker drives both halves of the sequence: they queue commands that stall the device (SG_IO lets the caller pick the command timeout, and queue saturation or long-running opcodes reliably produce timeouts), which forces scsi_send_eh_cmnd() to re-submit the same scsi_cmnd at the same tag, and the WARN_ON plus descriptor/PRDT rewrite then follow deterministically. Nothing in the trigger depends on state the attacker cannot influence, and the attempt can be repeated indefinitely.\nPR:L - Only an ordinary local account is needed \u2014 any user generating I/O against UFS-backed storage can have commands in flight that time out, and SG_IO on a readable block device (shell users on embedded/kiosk devices, `disk`-group members) lets the attacker choose the command timeout directly. No root, CAP_SYS_RAWIO, or namespace privilege is required to reach ufshcd_queuecommand() and the SCSI error handler path.\nUI:N - The SCSI error handler thread escalates and re-issues the command automatically once a timeout fires; no victim needs to mount a filesystem, open a file, or take any other action. The attacker\u0027s own I/O is sufficient.\nS:U - The corrupted state (lrbp-\u003ecmd, the transfer request descriptor, PRDT, DMA mappings, hba-\u003edev_cmd.complete) and all resulting damage stay inside the kernel that owns the UFS controller. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - Re-programming a transfer descriptor for a tag that is still in the controller doorbell mis-routes completions, so one command\u0027s response UPIU and sense data are delivered as another command\u0027s result, and the spurious complete(hba-\u003edev_cmd.complete) makes ufshcd_wait_for_dev_cmd() read hba-\u003edev_cmd.cqe and lrbp-\u003eucd_rsp_ptr while the controller is still writing them. Combined with the orphaned DMA mapping that leaves the device able to read pages after they are freed and reused, this yields disclosure of arbitrary kernel memory contents.\nI:H - ufshcd_map_sg() calls scsi_dma_map() a second time and rewrites the PRDT for a tag the controller is actively executing, and ufshcd_release_scsi_cmd() unmaps only one of the two mappings \u2014 leaving the UFS controller with DMA write access to pages that are subsequently freed and reallocated. Device-driven writes into reused kernel memory, plus the recycled device-management reserved slot being reprogrammed under an in-flight transfer, constitute kernel memory corruption usable for control-flow hijack.\nA:H - The documented symptom is a WARNING at ufshcd.c:2965 in ufshcd_queuecommand() from the SCSI error handler, which is an immediate kernel panic on the panic_on_warn configurations used by Android GKI, ChromeOS, and hardened embedded builds. Even without panic_on_warn, the descriptor/doorbell confusion and the falsely completed device-management command wedge the UFS error handler and the system\u0027s only storage device."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix potential out-of-bound accesses for Extigy and Mbox devices
A bogus device can provide a bNumConfigurations value that exceeds the
initial value used in usb_get_configuration for allocating dev->config.
This can lead to out-of-bounds accesses later, e.g. in
usb_destroy_configuration.

Summary
In the Linux kernel, the following vulnerability has been resolved:
soc: qcom: ocmem: Fix refcount leak in of_get_ocmem
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
of_node_put() will check NULL pointer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tunnels: fix kasan splat when generating ipv4 pmtu error
If we try to emit an icmp error in response to a nonliner skb, we get
BUG: KASAN: slab-out-of-bounds in ip_compute_csum+0x134/0x220
Read of size 4 at addr ffff88811c50db00 by task iperf3/1691
CPU: 2 PID: 1691 Comm: iperf3 Not tainted 6.5.0-rc3+ #309
[..]
kasan_report+0x105/0x140
ip_compute_csum+0x134/0x220
iptunnel_pmtud_build_icmp+0x554/0x1020
skb_tunnel_check_pmtu+0x513/0xb80
vxlan_xmit_one+0x139e/0x2ef0
vxlan_xmit+0x1867/0x2760
dev_hard_start_xmit+0x1ee/0x4f0
br_dev_queue_push_xmit+0x4d1/0x660
[..]
ip_compute_csum() cannot deal with nonlinear skbs, so avoid it.
After this change, splat is gone and iperf3 is no longer stuck.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: ipu-bridge: Fix null pointer deref on SSDB/PLD parsing warnings
When ipu_bridge_parse_rotation() and ipu_bridge_parse_orientation() run
sensor->adev is not set yet.
So if either of the dev_warn() calls about unknown values are hit this
will lead to a NULL pointer deref.
Set sensor->adev earlier, with a borrowed ref to avoid making unrolling
on errors harder, to fix this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: sync_linked_regs() must preserve subreg_def
Range propagation must not affect subreg_def marks, otherwise the
following example is rewritten by verifier incorrectly when
BPF_F_TEST_RND_HI32 flag is set:
0: call bpf_ktime_get_ns call bpf_ktime_get_ns
1: r0 &= 0x7fffffff after verifier r0 &= 0x7fffffff
2: w1 = w0 rewrites w1 = w0
3: if w0 < 10 goto +0 --------------> r11 = 0x2f5674a6 (r)
4: r1 >>= 32 r11 <<= 32 (r)
5: r0 = r1 r1 |= r11 (r)
6: exit; if w0 < 0xa goto pc+0
r1 >>= 32
r0 = r1
exit
(or zero extension of w1 at (2) is missing for architectures that
require zero extension for upper register half).
The following happens w/o this patch:
- r0 is marked as not a subreg at (0);
- w1 is marked as subreg at (2);
- w1 subreg_def is overridden at (3) by copy_register_state();
- w1 is read at (5) but mark_insn_zext() does not mark (2)
for zero extension, because w1 subreg_def is not set;
- because of BPF_F_TEST_RND_HI32 flag verifier inserts random
value for hi32 bits of (2) (marked (r));
- this random value is read at (5).

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/64: Init jump labels before parse_early_param()
On 64-bit, calling jump_label_init() in setup_feature_keys() is too
late because static keys may be used in subroutines of
parse_early_param() which is again subroutine of early_init_devtree().
For example booting with "threadirqs":
static_key_enable_cpuslocked(): static key '0xc000000002953260' used before call to jump_label_init()
WARNING: CPU: 0 PID: 0 at kernel/jump_label.c:166 static_key_enable_cpuslocked+0xfc/0x120
...
NIP static_key_enable_cpuslocked+0xfc/0x120
LR static_key_enable_cpuslocked+0xf8/0x120
Call Trace:
static_key_enable_cpuslocked+0xf8/0x120 (unreliable)
static_key_enable+0x30/0x50
setup_forced_irqthreads+0x28/0x40
do_early_param+0xa0/0x108

parse_early_param+0x58/0x84

So call jump_label_init() just before parse_early_param() in
early_init_devtree().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ibmvnic: Do not reset dql stats on NON_FATAL err
All ibmvnic resets, make a call to netdev_tx_reset_queue() when
re-opening the device. netdev_tx_reset_queue() resets the num_queued
and num_completed byte counters. These stats are used in Byte Queue
Limit (BQL) algorithms. The difference between these two stats tracks
the number of bytes currently sitting on the physical NIC. ibmvnic
increases the number of queued bytes though calls to
netdev_tx_sent_queue() in the drivers xmit function. When, VIOS reports
that it is done transmitting bytes, the ibmvnic device increases the
number of completed bytes through calls to netdev_tx_completed_queue().
It is important to note that the driver batches its transmit calls and
num_queued is increased every time that an skb is added to the next
batch, not necessarily when the batch is sent to VIOS for transmission.
Unlike other reset types, a NON FATAL reset will not flush the sub crq
tx buffers. Therefore, it is possible for the batched skb array to be
partially full. So if there is call to netdev_tx_reset_queue() when
re-opening the device, the value of num_queued (0) would not account
for the skb's that are currently batched. Eventually, when the batch
is sent to VIOS, the call to netdev_tx_completed_queue() would increase
num_completed to a value greater than the num_queued. This causes a
BUG_ON crash:
ibmvnic 30000002: Firmware reports error, cause: adapter problem.

"value": "AV:L - The vulnerability is reached only by mounting a crafted HFS+ volume (loop-backed image or removable media) and then issuing ordinary syscalls \u2014 `unlink(2)`/`rmdir(2)` driving `hfsplus_delete_all_attrs` \u2192 `hfs_brec_remove` \u2192 `hfs_bnode_dump`, or `readdir`/`getxattr` driving `__hfs_brec_find`. No remote or network-facing consumer of fs/hfsplus/bnode.c exists.\nAC:L - The out-of-bounds index is taken verbatim from on-disk 16-bit fields the attacker authors \u2014 record offsets returned by `hfs_brec_lenoff()` and the node descriptor\u0027s `num_recs` \u2014 so a single purpose-built image triggers it deterministically on the first unlink. There is no race, timing window, or memory-layout precondition outside the attacker\u0027s control, and the adjacent kmalloc-192 slab contents can be groomed by repeated bnode allocations.\nPR:L - The bare `mount(2)` needs CAP_SYS_ADMIN since hfsplus is FS_REQUIRES_DEV without FS_USERNS_MOUNT, but in the most severe reasonable deployment an unprivileged local user routinely gets an attacker-controlled HFS+ image mounted via udisks2 loop-setup/mount in a desktop session, removable-media automounters on kiosks and embedded systems, or `user`/autofs fstab delegation. Once mounted, the unlink/rmdir/readdir that fires the bug needs no privilege at all.\nUI:N - The attacker performs every step personally \u2014 presents the crafted volume (which the automounter consumes without any human action) and then runs the unlink or rmdir that reaches `hfs_brec_remove()`. No second, victim user has to be induced into any action.\nS:U - The corruption occurs in HFS+ btree node handling inside the kernel and its effects stay within that same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The unvalidated index loads a `struct page *` from out-of-bounds slab memory and `memcpy_from_page()` then copies up to a full page from the arbitrary kernel address that pointer resolves to. That data lands in `fd-\u003ekey` and in catalog/attribute record buffers (bfind.c:222) that are handed straight back to userspace via readdir, getxattr, and listxattr, giving a repeatable arbitrary-kernel-memory disclosure primitive.\nI:H - The identical bogus `struct page *` is used on the write side by `hfs_bnode_write()`, `hfs_bnode_clear()`, `hfs_bnode_copy()`, and `hfs_bnode_move()`, whose `memcpy_to_page()`/`memmove()` deposit attacker-chosen bytes at an arbitrary kernel address. `hfs_brec_remove()` compounds this by passing `data_off - fd-\u003ekeyoffset - size`, which underflows from on-disk u16 values into an enormous length \u2014 an out-of-bounds write suitable for corrupting adjacent kernel objects and hijacking control flow.\nA:H - Dereferencing a garbage `struct page *` faults or corrupts memory in the middle of an unlink while holding the inode lock and the btree mutex, producing an oops that wedges the filesystem and leaks the held locks. On systems with `panic_on_oops` \u2014 standard in appliances, automotive, and embedded builds \u2014 it is an immediate full system panic, and the attacker can repeat it at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix BUG_ON() when directory entry has invalid rec_len
The rec_len field in the directory entry has to be a multiple of 4. A
corrupted filesystem image can be used to hit a BUG() in
ext4_rec_len_to_disk(), called from make_indexed_dir().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ftrace: Fix use-after-free for dynamic ftrace_ops
KASAN reported a use-after-free with ftrace ops [1]. It was found from
vmcore that perf had registered two ops with the same content
successively, both dynamic. After unregistering the second ops, a
use-after-free occurred.
In ftrace_shutdown(), when the second ops is unregistered, the
FTRACE_UPDATE_CALLS command is not set because there is another enabled
ops with the same content. Also, both ops are dynamic and the ftrace
callback function is ftrace_ops_list_func, so the
FTRACE_UPDATE_TRACE_FUNC command will not be set. Eventually the value
of 'command' will be 0 and ftrace_shutdown() will skip the rcu
synchronization.
However, ftrace may be activated. When the ops is released, another CPU
may be accessing the ops. Add the missing synchronization to fix this
problem.

Fix this by initializing hfc_tl timer with DEFINE_TIMER macro.
Also, use mod_timer instead of manual timeout update.

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: hi311x: populate ndo_change_mtu() to prevent buffer overflow
Sending an PF_PACKET allows to bypass the CAN framework logic and to
directly reach the xmit() function of a CAN driver. The only check
which is performed by the PF_PACKET framework is to make sure that
skb->len fits the interface's MTU.
Unfortunately, because the sun4i_can driver does not populate its
net_device_ops->ndo_change_mtu(), it is possible for an attacker to
configure an invalid MTU by doing, for example:
$ ip link set can0 mtu 9999
After doing so, the attacker could open a PF_PACKET socket using the
ETH_P_CANXL protocol:
socket(PF_PACKET, SOCK_RAW, htons(ETH_P_CANXL))
to inject a malicious CAN XL frames. For example:
struct canxl_frame frame = {
.flags = 0xff,
.len = 2048,
};
The CAN drivers' xmit() function are calling can_dev_dropped_skb() to
check that the skb is valid, unfortunately under above conditions, the
malicious packet is able to go through can_dev_dropped_skb() checks:
1. the skb->protocol is set to ETH_P_CANXL which is valid (the
function does not check the actual device capabilities).
2. the length is a valid CAN XL length.
And so, hi3110_hard_start_xmit() receives a CAN XL frame which it is
not able to correctly handle and will thus misinterpret it as a CAN
frame. The driver will consume frame->len as-is with no further
checks.
This can result in a buffer overflow later on in hi3110_hw_tx() on
this line:
memcpy(buf + HI3110_FIFO_EXT_DATA_OFF,
frame->data, frame->len);
Here, frame->len corresponds to the flags field of the CAN XL frame.
In our previous example, we set canxl_frame->flags to 0xff. Because
the maximum expected length is 8, a buffer overflow of 247 bytes
occurs!
Populate net_device_ops->ndo_change_mtu() to ensure that the
interface's MTU can not be set to anything bigger than CAN_MTU. By
fixing the root cause, this prevents the buffer overflow.

The only check\nwhich is performed by the PF_PACKET framework is to make sure that\nskb-\u003elen fits the interface\u0027s MTU.\n\nUnfortunately, because the sun4i_can driver does not populate its\nnet_device_ops-\u003endo_change_mtu(), it is possible for an attacker to\nconfigure an invalid MTU by doing, for example:\n\n $ ip link set can0 mtu 9999\n\nAfter doing so, the attacker could open a PF_PACKET socket using the\nETH_P_CANXL protocol:\n\n\tsocket(PF_PACKET, SOCK_RAW, htons(ETH_P_CANXL))\n\nto inject a malicious CAN XL frames. For example:\n\n\tstruct canxl_frame frame = {\n\t\t.flags = 0xff,\n\t\t.len = 2048,\n\t};\n\nThe CAN drivers\u0027 xmit() function are calling can_dev_dropped_skb() to\ncheck that the skb is valid, unfortunately under above conditions, the\nmalicious packet is able to go through can_dev_dropped_skb() checks:\n\n 1. the skb-\u003eprotocol is set to ETH_P_CANXL which is valid (the\n function does not check the actual device capabilities).\n\n 2. the length is a valid CAN XL length.\n\nAnd so, hi3110_hard_start_xmit() receives a CAN XL frame which it is\nnot able to correctly handle and will thus misinterpret it as a CAN\nframe. The driver will consume frame-\u003elen as-is with no further\nchecks.\n\nThis can result in a buffer overflow later on in hi3110_hw_tx() on\nthis line:\n\n\tmemcpy(buf + HI3110_FIFO_EXT_DATA_OFF,\n\t frame-\u003edata, frame-\u003elen);\n\nHere, frame-\u003elen corresponds to the flags field of the CAN XL frame.\nIn our previous example, we set canxl_frame-\u003eflags to 0xff. Because\nthe maximum expected length is 8, a buffer overflow of 247 bytes\noccurs!\n\nPopulate net_device_ops-\u003endo_change_mtu() to ensure that the\ninterface\u0027s MTU can not be set to anything bigger than CAN_MTU. By\nfixing the root cause, this prevents the buffer overflow."

Summary
In the Linux kernel, the following vulnerability has been resolved:
hfsplus: don't use BUG_ON() in hfsplus_create_attributes_file()
When the volume header contains erroneous values that do not reflect
the actual state of the filesystem, hfsplus_fill_super() assumes that
the attributes file is not yet created, which later results in hitting
BUG_ON() when hfsplus_create_attributes_file() is called. Replace this
BUG_ON() with -EIO error with a message to suggest running fsck tool.

When setup a vlan device on dev pim6reg, DAD ns packet may sent on reg_vif_xmit().
reg_vif_xmit()
ip6mr_cache_report()
skb_push(skb, -skb_network_offset(pkt));//skb_network_offset(pkt) is 4
And skb_push declared as:
void *skb_push(struct sk_buff *skb, unsigned int len);
skb->data -= len;
//0xffff88805f86a84c - 0xfffffffc = 0xffff887f5f86a850
skb->data is set to 0xffff887f5f86a850, which is invalid mem addr, lead to skb_push() fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix race issue between cpu buffer write and swap
Warning happened in rb_end_commit() at code:
if (RB_WARN_ON(cpu_buffer, !local_read(&cpu_buffer->committing)))
WARNING: CPU: 0 PID: 139 at kernel/trace/ring_buffer.c:3142
rb_commit+0x402/0x4a0
Call Trace:
ring_buffer_unlock_commit+0x42/0x250

__schedule+0x72b/0x1580

worker_thread+0xa0/0x6f0
It is because the race between writing event into cpu buffer and swapping
cpu buffer through file per_cpu/cpu0/snapshot:
Write on CPU 0 Swap buffer by per_cpu/cpu0/snapshot on CPU 1
-------- --------
tracing_snapshot_write()
[...]
ring_buffer_lock_reserve()
cpu_buffer = buffer->buffers[cpu]; // 1. Suppose find 'cpu_buffer_a';
[...]
rb_reserve_next_event()
[...]
ring_buffer_swap_cpu()
if (local_read(&cpu_buffer_a->committing))
goto out_dec;
if (local_read(&cpu_buffer_b->committing))
goto out_dec;
buffer_a->buffers[cpu] = cpu_buffer_b;
buffer_b->buffers[cpu] = cpu_buffer_a;
// 2. cpu_buffer has swapped here.
rb_start_commit(cpu_buffer);
if (unlikely(READ_ONCE(cpu_buffer->buffer)
!= buffer)) { // 3. This check passed due to 'cpu_buffer->buffer'
[...] // has not changed here.
return NULL;
}
cpu_buffer_b->buffer = buffer_a;
cpu_buffer_a->buffer = buffer_b;
[...]
// 4. Reserve event from 'cpu_buffer_a'.
ring_buffer_unlock_commit()
[...]
cpu_buffer = buffer->buffers[cpu]; // 5. Now find 'cpu_buffer_b' !!!
rb_commit(cpu_buffer)
rb_end_commit() // 6. WARN for the wrong 'committing' state !!!
Based on above analysis, we can easily reproduce by following testcase:
``` bash
#!/bin/bash
dmesg -n 7
sysctl -w kernel.panic_on_warn=1
TR=/sys/kernel/tracing
echo 7 > ${TR}/buffer_size_kb
echo "sched:sched_switch" > ${TR}/set_event
while [ true ]; do
echo 1 > ${TR}/per_cpu/cpu0/snapshot
done &
while [ true ]; do
echo 1 > ${TR}/per_cpu/cpu0/snapshot
done &
while [ true ]; do
echo 1 > ${TR}/per_cpu/cpu0/snapshot
done &
```
To fix it, IIUC, we can use smp_call_function_single() to do the swap on
the target cpu where the buffer is located, so that above race would be
avoided.

Summary
In the Linux kernel, the following vulnerability has been resolved:
md/raid10: check slab-out-of-bounds in md_bitmap_get_counter
If we write a large number to md/bitmap_set_bits, md_bitmap_checkpage()
will return -EINVAL because 'page >= bitmap->pages', but the return value
was not checked immediately in md_bitmap_get_counter() in order to set
*blocks value and slab-out-of-bounds occurs.
Move check of 'page >= bitmap->pages' to md_bitmap_get_counter() and
return directly if true.

Summary
In the Linux kernel, the following vulnerability has been resolved:
exfat: add cluster chain loop check for dir
An infinite loop may occur if the following conditions occur due to
file system corruption.
(1) Condition for exfat_count_dir_entries() to loop infinitely.
- The cluster chain includes a loop.
- There is no UNUSED entry in the cluster chain.
(2) Condition for exfat_create_upcase_table() to loop infinitely.
- The cluster chain of the root directory includes a loop.
- There are no UNUSED entry and up-case table entry in the cluster
chain of the root directory.
(3) Condition for exfat_load_bitmap() to loop infinitely.
- The cluster chain of the root directory includes a loop.
- There are no UNUSED entry and bitmap entry in the cluster chain
of the root directory.
(4) Condition for exfat_find_dir_entry() to loop infinitely.
- The cluster chain includes a loop.
- The unused directory entries were exhausted by some operation.
(5) Condition for exfat_check_dir_empty() to loop infinitely.
- The cluster chain includes a loop.
- The unused directory entries were exhausted by some operation.
- All files and sub-directories under the directory are deleted.
This commit adds checks to break the above infinite loop.

Summary
In the Linux kernel, the following vulnerability has been resolved:
perf/x86/amd/core: Always clear status for idx
The variable 'status' (which contains the unhandled overflow bits) is
not being properly masked in some cases, displaying the following
warning:
WARNING: CPU: 156 PID: 475601 at arch/x86/events/amd/core.c:972 amd_pmu_v2_handle_irq+0x216/0x270
This seems to be happening because the loop is being continued before
the status bit being unset, in case x86_perf_event_set_period()
returns 0. This is also causing an inconsistency because the "handled"
counter is incremented, but the status bit is not cleaned.
Move the bit cleaning together above, together when the "handled"
counter is incremented.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: u_serial: Add null pointer check in gserial_suspend
Consider a case where gserial_disconnect has already cleared
gser->ioport. And if gserial_suspend gets called afterwards,
it will lead to accessing of gser->ioport and thus causing
null pointer dereference.
Avoid this by adding a null pointer check. Added a static
spinlock to prevent gser->ioport from becoming null after
the newly added null pointer check.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: multitouch: fix slab out-of-bounds access in mt_report_fixup()
A malicious HID device can trigger a slab out-of-bounds during
mt_report_fixup() by passing in report descriptor smaller than
607 bytes. mt_report_fixup() attempts to patch byte offset 607
of the descriptor with 0x25 by first checking if byte offset
607 is 0x15 however it lacks bounds checks to verify if the
descriptor is big enough before conducting this check. Fix
this bug by ensuring the descriptor size is at least 608
bytes before accessing it.
Below is the KASAN splat after the out of bounds access happens:

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: LAG, fix logic over MLX5_LAG_FLAG_NDEVS_READY
Only set MLX5_LAG_FLAG_NDEVS_READY if both netdevices are registered.
Doing so guarantees that both ldev->pf[MLX5_LAG_P0].dev and
ldev->pf[MLX5_LAG_P1].dev have valid pointers when
MLX5_LAG_FLAG_NDEVS_READY is set.
The core issue is asymmetry in setting MLX5_LAG_FLAG_NDEVS_READY and
clearing it. Setting it is done wrongly when both
ldev->pf[MLX5_LAG_P0].dev and ldev->pf[MLX5_LAG_P1].dev are set;
clearing it is done right when either of ldev->pf[i].netdev is cleared.
Consider the following scenario:
1. PF0 loads and sets ldev->pf[MLX5_LAG_P0].dev to a valid pointer
2. PF1 loads and sets both ldev->pf[MLX5_LAG_P1].dev and
ldev->pf[MLX5_LAG_P1].netdev with valid pointers. This results in
MLX5_LAG_FLAG_NDEVS_READY is set.
3. PF0 is unloaded before setting dev->pf[MLX5_LAG_P0].netdev.
MLX5_LAG_FLAG_NDEVS_READY remains set.
Further execution of mlx5_do_bond() will result in null pointer
dereference when calling mlx5_lag_is_multipath()
This patch fixes the following call trace actually encountered:

Above issue happens as follows:
ext4_iget
ext4_find_inline_data_nolock ->i_inline_off=164 i_inline_size=60
ext4_try_add_inline_entry
__ext4_mark_inode_dirty
ext4_expand_extra_isize_ea ->i_extra_isize=32 s_want_extra_isize=44
ext4_xattr_shift_entries
->after shift i_inline_off is incorrect, actually is change to 176
ext4_try_add_inline_entry
ext4_update_inline_dir
get_max_inline_xattr_value_size
if (EXT4_I(inode)->i_inline_off)
entry = (struct ext4_xattr_entry *)((void *)raw_inode +
EXT4_I(inode)->i_inline_off);
free += EXT4_XATTR_SIZE(le32_to_cpu(entry->e_value_size));
->As entry is incorrect, then 'free' may be negative
ext4_update_inline_data
value = kzalloc(len, GFP_NOFS);
-> len is unsigned int, maybe very large, then trigger warning when
'kzalloc()'
To resolve the above issue we need to update 'i_inline_off' after
'ext4_xattr_shift_entries()'. We do not need to set
EXT4_STATE_MAY_INLINE_DATA flag here, since ext4_mark_inode_dirty()
already sets this flag if needed. Setting EXT4_STATE_MAY_INLINE_DATA
when it is needed may trigger a BUG_ON in ext4_writepages().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix memory leaks in ext4_fname_{setup_filename,prepare_lookup}
If the filename casefolding fails, we'll be leaking memory from the
fscrypt_name struct, namely from the 'crypto_buf.name' member.
Make sure we free it in the error path on both ext4_fname_setup_filename()
and ext4_fname_prepare_lookup() functions.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: Correct tid cleanup when tid setup fails
Currently, if any error occurs during ath12k_dp_rx_peer_tid_setup(),
the tid value is already incremented, even though the corresponding
TID is not actually allocated. Proceed to
ath12k_dp_rx_peer_tid_delete() starting from unallocated tid,
which might leads to freeing unallocated TID and cause potential
crash or out-of-bounds access.
Hence, fix by correctly decrementing tid before cleanup to match only
the successfully allocated TIDs.
Also, remove tid-- from failure case of ath12k_dp_rx_peer_frag_setup(),
as decrementing the tid before cleanup in loop will take care of this.
Compile tested only.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: qgroup: fix race between quota disable and quota rescan ioctl
There's a race between a task disabling quotas and another running the
rescan ioctl that can result in a use-after-free of qgroup records from
the fs_info->qgroup_tree rbtree.
This happens as follows:
1) Task A enters btrfs_ioctl_quota_rescan() -> btrfs_qgroup_rescan();
2) Task B enters btrfs_quota_disable() and calls
btrfs_qgroup_wait_for_completion(), which does nothing because at that
point fs_info->qgroup_rescan_running is false (it wasn't set yet by
task A);
3) Task B calls btrfs_free_qgroup_config() which starts freeing qgroups
from fs_info->qgroup_tree without taking the lock fs_info->qgroup_lock;
4) Task A enters qgroup_rescan_zero_tracking() which starts iterating
the fs_info->qgroup_tree tree while holding fs_info->qgroup_lock,
but task B is freeing qgroup records from that tree without holding
the lock, resulting in a use-after-free.
Fix this by taking fs_info->qgroup_lock at btrfs_free_qgroup_config().
Also at btrfs_qgroup_rescan() don't start the rescan worker if quotas
were already disabled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio_net: fix memory leak inside XPD_TX with mergeable
When we call xdp_convert_buff_to_frame() to get xdpf, if it returns
NULL, we should check if xdp_page was allocated by xdp_linearize_page().
If it is newly allocated, it should be freed here alone. Just like any
other "goto err_xdp".

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: minimal: fix potential memory leak in mlxsw_m_linecards_init
The line cards array is not freed in the error path of
mlxsw_m_linecards_init(), which can lead to a memory leak. Fix by
freeing the array in the error path, thereby making the error path
identical to mlxsw_m_linecards_fini().

Summary
In the Linux kernel, the following vulnerability has been resolved:
vxlan: Fix NPD when refreshing an FDB entry with a nexthop object
VXLAN FDB entries can point to either a remote destination or an FDB
nexthop group. The latter is usually used in EVPN deployments where
learning is disabled.
However, when learning is enabled, an incoming packet might try to
refresh an FDB entry that points to an FDB nexthop group and therefore
does not have a remote. Such packets should be dropped, but they are
only dropped after dereferencing the non-existent remote, resulting in a
NPD [1] which can be reproduced using [2].
Fix by dropping such packets earlier. Remove the misleading comment from
first_remote_rcu().

VXLAN underlays are L3-routed, so the attacker is not confined to the local segment.\nAC:L - One unsolicited packet whose inner source MAC matches an nh-backed FDB entry triggers the NULL dereference deterministically \u2014 no race, no memory-layout grooming, no timing window. Learning is the kernel default for new VXLAN devices and nexthop-backed FDB entries are standard EVPN programming, so the required state is ordinary deployment configuration rather than a condition outside the attacker\u0027s control.\nPR:N - VXLAN carries no authentication and `vxlan_rcv` performs no source-address or peer validation before handing the inner frame to `vxlan_snoop`. An entirely unauthenticated off-box attacker needs no credentials or account on the target.\nUI:N - The crash happens during packet receive processing with no involvement from any local user or administrator. No victim action of any kind is required.\nS:U - The fault occurs in the kernel and its impact is confined to that same kernel\u0027s security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:N - The dereference is a read of `remote_ip` at offset 0 (and `remote_ifindex` nearby) from a NULL pointer, well inside the unmapped guard page, so no data is read or returned to the attacker. Nothing is disclosed before the fault aborts execution.\nI:N - Execution faults at the read in `vxlan_addr_equal()`, before the `rdst-\u003eremote_ip = *src_ip` assignment, so no write or state modification ever occurs. This is a pure NULL-pointer read with no corruption or control-flow primitive.\nA:H - The NULL dereference oopses in softirq/NAPI context, which takes the `in_interrupt()` path in `die()` and panics the machine (\"Fatal exception in interrupt\") rather than merely killing a task. A remote attacker can repeat the single triggering packet at will for a persistent whole-system denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
driver core: fix potential deadlock in __driver_attach
In __driver_attach function, There are also AA deadlock problem,
like the commit b232b02bf3c2 ("driver core: fix deadlock in
__device_attach").
stack like commit b232b02bf3c2 ("driver core: fix deadlock in
__device_attach").
list below:
In __driver_attach function, The lock holding logic is as follows:
...
__driver_attach
if (driver_allows_async_probing(drv))
device_lock(dev) // get lock dev
async_schedule_dev(__driver_attach_async_helper, dev); // func
async_schedule_node
async_schedule_node_domain(func)
entry = kzalloc(sizeof(struct async_entry), GFP_ATOMIC);
/* when fail or work limit, sync to execute func, but
__driver_attach_async_helper will get lock dev as
will, which will lead to A-A deadlock. */
if (!entry || atomic_read(&entry_count) > MAX_WORK) {
func;
else
queue_work_node(node, system_unbound_wq, &entry->work)
device_unlock(dev)
As above show, when it is allowed to do async probes, because of
out of memory or work limit, async work is not be allowed, to do
sync execute instead. it will lead to A-A deadlock because of
__driver_attach_async_helper getting lock dev.
Reproduce:
and it can be reproduce by make the condition
(if (!entry || atomic_read(&entry_count) > MAX_WORK)) untenable, like
below:
[ 370.785650] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables

To fix the deadlock, move the async_schedule_dev outside device_lock,
as we can see, in async_schedule_node_domain, the parameter of
queue_work_node is system_unbound_wq, so it can accept concurrent
operations. which will also not change the code logic, and will
not lead to deadlock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, cpumap: Handle skb as well when clean up ptr_ring
The following warning was reported when running xdp_redirect_cpu with
both skb-mode and stress-mode enabled:
------------[ cut here ]------------
Incorrect XDP memory type (-2128176192) usage
WARNING: CPU: 7 PID: 1442 at net/core/xdp.c:405

The reason for the warning is twofold. One is due to the kthread
cpu_map_kthread_run() is stopped prematurely. Another one is
__cpu_map_ring_cleanup() doesn't handle skb mode and treats skbs in
ptr_ring as XDP frames.
Prematurely-stopped kthread will be fixed by the preceding patch and
ptr_ring will be empty when __cpu_map_ring_cleanup() is called. But
as the comments in __cpu_map_ring_cleanup() said, handling and freeing
skbs in ptr_ring as well to "catch any broken behaviour gracefully".

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix memory leak in test_gen_synth_cmd() and test_empty_synth_event()
test_gen_synth_cmd() only free buf in fail path, hence buf will leak
when there is no failure. Add kfree(buf) to prevent the memleak. The
same reason and solution in test_empty_synth_event().

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix incomplete state save in rxe_requester
If a send packet is dropped by the IP layer in rxe_requester()
the call to rxe_xmit_packet() can fail with err == -EAGAIN.
To recover, the state of the wqe is restored to the state before
the packet was sent so it can be resent. However, the routines
that save and restore the state miss a significnt part of the
variable state in the wqe, the dma struct which is used to process
through the sge table. And, the state is not saved before the packet
is built which modifies the dma struct.
Under heavy stress testing with many QPs on a fast node sending
large messages to a slow node dropped packets are observed and
the resent packets are corrupted because the dma struct was not
restored. This patch fixes this behavior and allows the test cases
to succeed.

However, the routines\nthat save and restore the state miss a significnt part of the\nvariable state in the wqe, the dma struct which is used to process\nthrough the sge table. And, the state is not saved before the packet\nis built which modifies the dma struct.\n\nUnder heavy stress testing with many QPs on a fast node sending\nlarge messages to a slow node dropped packets are observed and\nthe resent packets are corrupted because the dma struct was not\nrestored. This patch fixes this behavior and allows the test cases\nto succeed."

The triggering error also originates in the local IP/qdisc layer.\nAC:L - The attacker fully controls the condition that produces the -EAGAIN drop \u2014 the commit itself describes it arising from many QPs sending large messages, and an unprivileged user can additionally saturate the outbound qdisc of the same netdev to force NET_XMIT_DROP on demand. The rollback path is then hit deterministically and can be retried indefinitely.\nPR:L - Only an unprivileged local account is needed: rdma-core udev rules expose /dev/infiniband/uverbs* mode 0666, so any user (including inside a container) can create QPs and post sends once an rxe link exists. No capability check gates the requester path.\nUI:N - The attacker\u0027s own posted sends plus self-generated network congestion drive the entire sequence; no action by any other user or administrator is required.\nS:U - The corrupted state and its effects stay within the kernel\u0027s RDMA subsystem and the QPs of the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The desynchronized dma cursor makes the requester transmit a different region of registered memory than the PSN/opcode declares, so registered buffer contents are delivered to memory offsets the application never intended, and short/zero-payload packets (e.g. ATOMIC_WRITE with resid already 0) drive the receiving responder to consume data past the declared payload. Treating the state corruption as leverageable for disclosure, this is scored High.\nI:H - This is the core impact \u2014 resent packets carry the wrong SGE data, so a multi-packet SEND or RDMA WRITE silently writes truncated/shifted content into the peer\u0027s registered memory while the local completion still reports IB_WC_SUCCESS, giving undetected corruption of application and (for NFS/RDMA, iSER, NVMe-oF, SMB Direct over rxe) on-disk data.\nA:H - When the dropped packet was the LAST of a message, the retry emits a zero-length END packet that the responder rejects with RESPST_ERR_LENGTH (rxe_resp.c:378-382), and early-terminated WRITEs trip the pktlen check in check_rkey(); either produces NAK_INVALID_REQUEST, driving both RC QPs into the error state and destroying the connection along with all in-flight and queued work."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: tun: Fix memory leaks of napi_get_frags
kmemleak reports after running test_progs:
unreferenced object 0xffff8881b1672dc0 (size 232):

The issue occurs in the following scenarios:
tun_get_user()
napi_gro_frags()
napi_frags_finish()
case GRO_NORMAL:
gro_normal_one()
list_add_tail(&skb->list, &napi->rx_list);
<-- While napi->rx_count < READ_ONCE(gro_normal_batch),
<-- gro_normal_list() is not called, napi->rx_list is not empty
<-- not ask to complete the gro work, will cause memory leaks in
<-- following tun_napi_del()
...
tun_napi_del()
netif_napi_del()
__netif_napi_del()
<-- &napi->rx_list is not empty, which caused memory leaks
To fix, add napi_complete() after napi_gro_frags().

Summary
In the Linux kernel, the following vulnerability has been resolved:
iavf: Fix out-of-bounds when setting channels on remove
If we set channels greater during iavf_remove(), and waiting reset done
would be timeout, then returned with error but changed num_active_queues
directly, that will lead to OOB like the following logs. Because the
num_active_queues is greater than tx/rx_rings[] allocated actually.

"value": "AV:L - The vulnerable function is reached only through the ethtool interface \u2014 `SIOCETHTOOL`/`ETHTOOL_SCHANNELS` ioctl or the `ETHTOOL_MSG_CHANNELS_SET` genetlink message \u2014 both of which require a local process on the machine running the iavf driver. No remote or adjacent-network packet path reaches `iavf_set_channels()`.\nAC:L - The attacker fully drives the triggering side and can spam `ethtool -L \u003cif\u003e combined 1/16` in a tight loop indefinitely at no cost; the required 20-second reset stall recurs routinely in the SR-IOV lifecycle (VF hot-plug/unplug, `sriov_numvfs` changes, PF driver reset, FLR, PF saturated by many simultaneous VF resets), so the OOB fires reliably rather than requiring a one-shot narrow window. Once `iavf_reset_task` enters its own 20 s \"reset never finished\" wait, any concurrently-waiting `ethtool -L` is guaranteed to time out and corrupt the counter.\nPR:L - Setting channels is gated on `ns_capable(net-\u003euser_ns, CAP_NET_ADMIN)` / `GENL_UNS_ADMIN_PERM`, i.e. CAP_NET_ADMIN relative to the owning user namespace, which an unprivileged user holds inside a user+network namespace \u2014 the standard SR-IOV-to-container deployment (SR-IOV CNI / DPDK / telco pods) moves the VF netdev into exactly such a namespace. Additionally, harvesting the resulting out-of-bounds data via `ethtool -S` (`ETHTOOL_GSTATS`) requires no privileges at all.\nUI:N - The attacker performs the entire sequence themselves with ethtool calls; no victim action, file open, or mount is needed. The concurrent reset stall is a device/PF lifecycle event, not a user interaction.\nS:U - The out-of-bounds accesses corrupt kernel slab memory belonging to the same kernel that the attacker is already interacting with; no VM, IOMMU, or sandbox boundary is crossed. Standard local kernel memory-corruption scope.\nC:H - With the counter inflated, `iavf_get_ethtool_stats()` reads `tx_rings[i]`/`rx_rings[i]` far past the kcalloc\u0027d array and copies those adjacent kernel-heap u64s directly into a userspace buffer via `ethtool -S`, which needs no privileges \u2014 a clean, repeatable multi-kilobyte heap disclosure including kernel pointers.\nI:H - `iavf_configure_tx()`/`iavf_configure_rx()` write `tail`, `rx_buf_len` and `flags` past the end of the array, and `iavf_free_tx_resources()` calls `kfree()`, `memset(desc, 0, size)` and `dma_free_coherent()` on pointers/sizes read out of bounds \u2014 an arbitrary-free and arbitrary-zeroing primitive over groomable heap that is exploitable for control-flow hijack.\nA:H - The commit\u0027s own reproducer produces a KASAN slab-out-of-bounds oops in `iavf_free_all_tx_resources()` during `iavf_remove()`; the racing `iavf_disable_vf()` path additionally leaves `tx_rings`/`rx_rings` NULL with a non-zero counter, giving a NULL+offset dereference. Either way the result is a kernel panic, plus a 20-second rtnl_lock hold that stalls the whole networking stack."

After journal aborting, __jbd2_journal_refile_buffer() is executed with
holding @jh->b_state_lock, we can fix it by moving 'is_handle_aborted()'
into the area protected by @jh->b_state_lock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sch/netem: fix use after free in netem_dequeue
If netem_dequeue() enqueues packet to inner qdisc and that qdisc
returns __NET_XMIT_STOLEN. The packet is dropped but
qdisc_tree_reduce_backlog() is not called to update the parent's
q.qlen, leading to the similar use-after-free as Commit
e04991a48dbaf382 ("netem: fix return value if duplicate enqueue
fails")
Commands to trigger KASAN UaF:
ip link add type dummy
ip link set lo up
ip link set dummy0 up
tc qdisc add dev lo parent root handle 1: drr
tc filter add dev lo parent 1: basic classid 1:1
tc class add dev lo classid 1:1 drr
tc qdisc add dev lo parent 1:1 handle 2: netem
tc qdisc add dev lo parent 2: handle 3: drr
tc filter add dev lo parent 3: basic classid 3:1 action mirred egress
redirect dev dummy0
tc class add dev lo classid 3:1 drr
ping -c1 -W0.01 localhost # Trigger bug
tc class del dev lo classid 1:1
tc class add dev lo classid 1:1 drr
ping -c1 -W0.01 localhost # UaF

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: rainshadow-cec: fix TOCTOU race condition in rain_interrupt()
In the interrupt handler rain_interrupt(), the buffer full check on
rain->buf_len is performed before acquiring rain->buf_lock. This
creates a Time-of-Check to Time-of-Use (TOCTOU) race condition, as
rain->buf_len is concurrently accessed and modified in the work
handler rain_irq_work_handler() under the same lock.
Multiple interrupt invocations can race, with each reading buf_len
before it becomes full and then proceeding. This can lead to both
interrupts attempting to write to the buffer, incrementing buf_len
beyond its capacity (DATA_SIZE) and causing a buffer overflow.
Fix this bug by moving the spin_lock() to before the buffer full
check. This ensures that the check and the subsequent buffer modification
are performed atomically, preventing the race condition. An corresponding
spin_unlock() is added to the overflow path to correctly release the
lock.
This possible bug was found by an experimental static analysis tool
developed by our team.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usbnet: Fix linkwatch use-after-free on disconnect
usbnet uses the work usbnet_deferred_kevent() to perform tasks which may
sleep. On disconnect, completion of the work was originally awaited in
->ndo_stop(). But in 2003, that was moved to ->disconnect() by historic
commit "[PATCH] USB: usbnet, prevent exotic rtnl deadlock":
https://git.kernel.org/tglx/history/c/0f138bbfd83c
The change was made because back then, the kernel's workqueue
implementation did not allow waiting for a single work. One had to wait
for completion of *all* work by calling flush_scheduled_work(), and that
could deadlock when waiting for usbnet_deferred_kevent() with rtnl_mutex
held in ->ndo_stop().
The commit solved one problem but created another: It causes a
use-after-free in USB Ethernet drivers aqc111.c, asix_devices.c,
ax88179_178a.c, ch9200.c and smsc75xx.c:
* If the drivers receive a link change interrupt immediately before
disconnect, they raise EVENT_LINK_RESET in their (non-sleepable)
->status() callback and schedule usbnet_deferred_kevent().
* usbnet_deferred_kevent() invokes the driver's ->link_reset() callback,
which calls netif_carrier_{on,off}().
* That in turn schedules the work linkwatch_event().
Because usbnet_deferred_kevent() is awaited after unregister_netdev(),
netif_carrier_{on,off}() may operate on an unregistered netdev and
linkwatch_event() may run after free_netdev(), causing a use-after-free.
In 2010, usbnet was changed to only wait for a single instance of
usbnet_deferred_kevent() instead of *all* work by commit 23f333a2bfaf
("drivers/net: don't use flush_scheduled_work()").
Unfortunately the commit neglected to move the wait back to
->ndo_stop(). Rectify that omission at long last.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: dw-axi-dmac: do not print NULL LLI during error
During debugging we have seen an issue where axi_chan_dump_lli()
is passed a NULL LLI pointer which ends up causing an OOPS due
to trying to get fields from it. Simply print NULL LLI and exit
to avoid this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
platform/x86: dell-sysman: Fix reference leak
If a duplicate attribute is found using kset_find_obj(),
a reference to that attribute is returned. This means
that we need to dispose it accordingly. Use kobject_put()
to dispose the duplicate attribute in such a case.
Compile-tested only.

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-iocost: use spin_lock_irqsave in adjust_inuse_and_calc_cost
adjust_inuse_and_calc_cost() use spin_lock_irq() and IRQ will be enabled
when unlock. DEADLOCK might happen if we have held other locks and disabled
IRQ before invoking it.
Fix it by using spin_lock_irqsave() instead, which can keep IRQ state
consistent with before when unlock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: rose: include node references in rose_neigh refcount
Current implementation maintains two separate reference counting
mechanisms: the 'count' field in struct rose_neigh tracks references from
rose_node structures, while the 'use' field (now refcount_t) tracks
references from rose_sock.
This patch merges these two reference counting systems using 'use' field
for proper reference management. Specifically, this patch adds incrementing
and decrementing of rose_neigh->use when rose_neigh->count is incremented
or decremented.
This patch also modifies rose_rt_free(), rose_rt_device_down() and
rose_clear_route() to properly release references to rose_neigh objects
before freeing a rose_node through rose_remove_node().
These changes ensure rose_neigh structures are properly freed only when
all references, including those from rose_node structures, are released.
As a result, this resolves a slab-use-after-free issue reported by Syzbot.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSv4.2: Rework scratch handling for READ_PLUS (again)
I found that the read code might send multiple requests using the same
nfs_pgio_header, but nfs4_proc_read_setup() is only called once. This is
how we ended up occasionally double-freeing the scratch buffer, but also
means we set a NULL pointer but non-zero length to the xdr scratch
buffer. This results in an oops the first time decoding needs to copy
something to scratch, which frequently happens when decoding READ_PLUS
hole segments.
I fix this by moving scratch handling into the pageio read code. I
provide a function to allocate scratch space for decoding read replies,
and free the scratch buffer when the nfs_pgio_header is freed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: set_page_extent_mapped after read_folio in btrfs_cont_expand
While trying to get the subpage blocksize tests running, I hit the
following panic on generic/476
assertion failed: PagePrivate(page) && page->private, in fs/btrfs/subpage.c:229
kernel BUG at fs/btrfs/subpage.c:229!

This happens because during btrfs_cont_expand we'll get a page, set it
as mapped, and if it's not Uptodate we'll read it. However between the
read and re-locking the page we could have called release_folio() on the
page, but left the page in the file mapping. release_folio() can clear
the page private, and thus further down we blow up when we go to modify
the subpage bits.
Fix this by putting the set_page_extent_mapped() after the read. This
is safe because read_folio() will call set_page_extent_mapped() before
it does the read, and then if we clear page private but leave it on the
mapping we're completely safe re-setting set_page_extent_mapped(). With
this patch I can now run generic/476 without panicing.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: move page table sync declarations to linux/pgtable.h
During our internal testing, we started observing intermittent boot
failures when the machine uses 4-level paging and has a large amount of
persistent memory:
BUG: unable to handle page fault for address: ffffe70000000034
#PF: supervisor write access in kernel mode
#PF: error_code(0x0002) - not-present page
PGD 0 P4D 0
Oops: 0002 [#1] SMP NOPTI
RIP: 0010:__init_single_page+0x9/0x6d

It turns out that the kernel panics while initializing vmemmap (struct
page array) when the vmemmap region spans two PGD entries, because the new
PGD entry is only installed in init_mm.pgd, but not in the page tables of
other tasks.
And looking at __populate_section_memmap():
if (vmemmap_can_optimize(altmap, pgmap))
// does not sync top level page tables
r = vmemmap_populate_compound_pages(pfn, start, end, nid, pgmap);
else
// sync top level page tables in x86
r = vmemmap_populate(start, end, nid, altmap);
In the normal path, vmemmap_populate() in arch/x86/mm/init_64.c
synchronizes the top level page table (See commit 9b861528a801 ("x86-64,
mem: Update all PGDs for direct mapping and vmemmap mapping changes")) so
that all tasks in the system can see the new vmemmap area.
However, when vmemmap_can_optimize() returns true, the optimized path
skips synchronization of top-level page tables. This is because
vmemmap_populate_compound_pages() is implemented in core MM code, which
does not handle synchronization of the top-level page tables. Instead,
the core MM has historically relied on each architecture to perform this
synchronization manually.
We're not the first party to encounter a crash caused by not-sync'd top
level page tables: earlier this year, Gwan-gyeong Mun attempted to address
the issue [1] [2] after hitting a kernel panic when x86 code accessed the
vmemmap area before the corresponding top-level entries were synced. At
that time, the issue was believed to be triggered only when struct page
was enlarged for debugging purposes, and the patch did not get further
updates.
It turns out that current approach of relying on each arch to handle the
page table sync manually is fragile because 1) it's easy to forget to sync
the top level page table, and 2) it's also easy to overlook that the
kernel should not access the vmemmap and direct mapping areas before the
sync.
# The solution: Make page table sync more code robust and harder to miss
To address this, Dave Hansen suggested [3] [4] introducing
{pgd,p4d}_populate_kernel() for updating kernel portion of the page tables
and allow each architecture to explicitly perform synchronization when
installing top-level entries. With this approach, we no longer need to
worry about missing the sync step, reducing the risk of future
regressions.
The new interface reuses existing ARCH_PAGE_TABLE_SYNC_MASK,
PGTBL_P*D_MODIFIED and arch_sync_kernel_mappings() facility used by
vmalloc and ioremap to synchronize page tables.
pgd_populate_kernel() looks like this:
static inline void pgd_populate_kernel(unsigned long addr, pgd_t *pgd,
p4d_t *p4d)
{
pgd_populate(&init_mm, pgd, p4d);
if (ARCH_PAGE_TABLE_SYNC_MASK & PGTBL_PGD_MODIFIED)
arch_sync_kernel_mappings(addr, addr);
}
It is worth noting that vmalloc() and apply_to_range() carefully
synchronizes page tables by calling p*d_alloc_track() and
arch_sync_kernel_mappings(), and thus they are not affected by

Summary
In the Linux kernel, the following vulnerability has been resolved:
mISDN: fix possible memory leak in mISDN_dsp_element_register()
Afer commit 1fa5ae857bb1 ("driver core: get rid of struct device's
bus_id string array"), the name of device is allocated dynamically,
use put_device() to give up the reference, so that the name can be
freed in kobject_cleanup() when the refcount is 0.
The 'entry' is going to be freed in mISDN_dsp_dev_release(), so the
kfree() is removed. list_del() is called in mISDN_dsp_dev_release(),
so it need be initialized.

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: fix oops in concurrently setting insn_emulation sysctls
emulation_proc_handler() changes table->data for proc_dointvec_minmax
and can generate the following Oops if called concurrently with itself:
| Unable to handle kernel NULL pointer dereference at virtual address 0000000000000010
| Internal error: Oops: 96000006 [#1] SMP
| Call trace:
| update_insn_emulation_mode+0xc0/0x148
| emulation_proc_handler+0x64/0xb8
| proc_sys_call_handler+0x9c/0xf8
| proc_sys_write+0x18/0x20
| __vfs_write+0x20/0x48
| vfs_write+0xe4/0x1d0
| ksys_write+0x70/0xf8
| __arm64_sys_write+0x20/0x28
| el0_svc_common.constprop.0+0x7c/0x1c0
| el0_svc_handler+0x2c/0xa0
| el0_svc+0x8/0x200
To fix this issue, keep the table->data as &insn->current_mode and
use container_of() to retrieve the insn pointer. Another mutex is
used to protect against the current_mode update but not for retrieving
insn_emulation as table->data is no longer changing.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: reject duplicate device on updates
A chain/flowtable update with duplicated devices in the same batch is
possible. Unfortunately, netdev event path only removes the first
device that is found, leaving unregistered the hook of the duplicated
device.
Check if a duplicated device exists in the transaction batch, bail out
with EEXIST in such case.
WARNING is hit when unregistering the hook:
[49042.221275] WARNING: CPU: 4 PID: 8425 at net/netfilter/core.c:340 nf_hook_entry_head+0xaa/0x150

Per kernel guidance, netfilter/nftables netlink configuration paths are Local.\nAC:L - The attacker deterministically constructs the condition by submitting a single batch containing two chain-update (or flowtable-update) messages naming the same device, then deleting that device; no race and no uncontrolled state is involved. CONFIG_NETFILTER_INGRESS and netdev-family chains are standard in distribution kernels.\nPR:L - nfnetlink only requires CAP_NET_ADMIN relative to the socket netns\u0027s user namespace (netlink_net_capable -\u003e netlink_ns_capable with sock_net(skb-\u003esk)-\u003euser_ns), so an unprivileged user gains it with unshare -Urn and can create dummy/veth devices, netdev chains and flowtables there. This is Low, not High.\nUI:N - The attacker performs every step \u2014 the duplicate-device batch, the commit, and the device removal \u2014 with no action from any other user or administrator.\nS:U - The corruption and its consequences stay within the kernel\u0027s own security authority; no VM, IOMMU, or hypervisor boundary is crossed. Escalation from a user namespace to kernel privileges is standard kernel privilege escalation, scored Unchanged.\nC:H - The stranded nf_hook_ops retains a dangling ops-\u003edev, and nf_hook_entry_head() dereferences the freed net_device (dev_net(dev)) on the next unregister \u2014 a use-after-free read. UAF of a groomable slab object gives the attacker control over the freed contents and an arbitrary-read path, so High.\nI:H - If the freed net_device is sprayed so nd_net matches, nf_hook_entry_head() returns a pointer into freed memory and __nf_unregister_net_hook()/nf_remove_net_hook()/__nf_hook_entries_tr y_shrink() then dereference and write through it, yielding a use-after-free write with an attacker-influenced nf_hook_entries pointer. The CHANGENAME variant also leaves a live ingress hook with ops-\u003ehook/ops-\u003epriv on freed basechain memory, reachable for control-flow hijack.\nA:H - The bug is confirmed to hit WARNING at nf_hook_entry_head+0xaa (net/netfilter/core.c) in the reporter\u0027s trace, and the underlying use-after-free on struct net_device causes oops/panic under KASAN or slab reuse. Any kernel crash is High."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Check for hdwq null ptr when cleaning up lpfc_vport structure
If a call to lpfc_sli4_read_rev() from lpfc_sli4_hba_setup() fails, the
resultant cleanup routine lpfc_sli4_vport_delete_fcp_xri_aborted() may
occur before sli4_hba.hdwqs are allocated. This may result in a null
pointer dereference when attempting to take the abts_io_buf_list_lock for
the first hardware queue. Fix by adding a null ptr check on
phba->sli4_hba.hdwq and early return because this situation means there
must have been an error during port initialization.

Summary
In the Linux kernel, the following vulnerability has been resolved:
proc: use the same treatment to check proc_lseek as ones for proc_read_iter et.al
Check pde->proc_ops->proc_lseek directly may cause UAF in rmmod scenario.
It's a gap in proc_reg_open() after commit 654b33ada4ab("proc: fix UAF in
proc_get_inode()"). Followed by AI Viro's suggestion, fix it in same
manner.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix NULL pointer deference in try_to_register_card
In try_to_register_card(), the return value of usb_ifnum_to_if() is
passed directly to usb_interface_claimed() without a NULL check, which
will lead to a NULL pointer dereference when creating an invalid
USB audio device. Fix this by adding a check to ensure the interface
pointer is valid before passing it to usb_interface_claimed().

In the Linux kernel, the following vulnerability has been resolved:
crypto: arm64/poly1305 - fix a read out-of-bound
A kasan error was reported during fuzzing:

This error can be reproduced by the following code compiled as ko on a
system with kasan enabled:
#include <linux/module.h>
#include <linux/crypto.h>
#include <crypto/hash.h>
#include <crypto/poly1305.h>
char test_data[] = "\x00\x01\x02\x03\x04\x05\x06\x07"
"\x08\x09\x0a\x0b\x0c\x0d\x0e\x0f"
"\x10\x11\x12\x13\x14\x15\x16\x17"
"\x18\x19\x1a\x1b\x1c\x1d\x1e";
int init(void)
{
struct crypto_shash *tfm = NULL;
char *data = NULL, *out = NULL;
tfm = crypto_alloc_shash("poly1305", 0, 0);
data = kmalloc(POLY1305_KEY_SIZE - 1, GFP_KERNEL);
out = kmalloc(POLY1305_DIGEST_SIZE, GFP_KERNEL);
memcpy(data, test_data, POLY1305_KEY_SIZE - 1);
crypto_shash_tfm_digest(tfm, data, POLY1305_KEY_SIZE - 1, out);
kfree(data);
kfree(out);
return 0;
}
void deinit(void)
{
}
module_init(init)
module_exit(deinit)
MODULE_LICENSE("GPL");
The root cause of the bug sits in neon_poly1305_blocks. The logic
neon_poly1305_blocks() performed is that if it was called with both s[]
and r[] uninitialized, it will first try to initialize them with the
data from the first "block" that it believed to be 32 bytes in length.
First 16 bytes are used as the key and the next 16 bytes for s[]. This
would lead to the aforementioned read out-of-bound. However, after
calling poly1305_init_arch(), only 16 bytes were deducted from the input
and s[] is initialized yet again with the following 16 bytes. The second
initialization of s[] is certainly redundent which indicates that the
first initialization should be for r[] only.
This patch fixes the issue by calling poly1305_init_arm64() instead o

Summary
In the Linux kernel, the following vulnerability has been resolved:
icmp6: Fix null-ptr-deref of ip6_null_entry->rt6i_idev in icmp6_dev().
With some IPv6 Ext Hdr (RPL, SRv6, etc.), we can send a packet that
has the link-local address as src and dst IP and will be forwarded to
an external IP in the IPv6 Ext Hdr.
For example, the script below generates a packet whose src IP is the
link-local address and dst is updated to 11::.
# for f in $(find /proc/sys/net/ -name *seg6_enabled*); do echo 1 > $f; done
# python3
>>> from socket import *
>>> from scapy.all import *
>>>
>>> SRC_ADDR = DST_ADDR = "fe80::5054:ff:fe12:3456"
>>>
>>> pkt = IPv6(src=SRC_ADDR, dst=DST_ADDR)
>>> pkt /= IPv6ExtHdrSegmentRouting(type=4, addresses=["11::", "22::"], segleft=1)
>>>
>>> sk = socket(AF_INET6, SOCK_RAW, IPPROTO_RAW)
>>> sk.sendto(bytes(pkt), (DST_ADDR, 0))
For such a packet, we call ip6_route_input() to look up a route for the
next destination in these three functions depending on the header type.
* ipv6_rthdr_rcv()
* ipv6_rpl_srh_rcv()
* ipv6_srh_rcv()
If no route is found, ip6_null_entry is set to skb, and the following
dst_input(skb) calls ip6_pkt_drop().
Finally, in icmp6_dev(), we dereference skb_rt6_info(skb)->rt6i_idev->dev
as the input device is the loopback interface. Then, we have to check if
skb_rt6_info(skb)->rt6i_idev is NULL or not to avoid NULL pointer deref
for ip6_null_entry.

Summary
In the Linux kernel, the following vulnerability has been resolved:
video: fbdev: arkfb: Check the size of screen before memset_io()
In the function arkfb_set_par(), the value of 'screen_size' is
calculated by the user input. If the user provides the improper value,
the value of 'screen_size' may larger than 'info->screen_size', which
may cause the following bug:
[ 659.399066] BUG: unable to handle page fault for address: ffffc90003000000
[ 659.399077] #PF: supervisor write access in kernel mode

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sched: Disallow replacing of child qdisc from one parent to another
Lion Ackermann was able to create a UAF which can be abused for privilege
escalation with the following script
Step 1. create root qdisc
tc qdisc add dev lo root handle 1:0 drr
step2. a class for packet aggregation do demonstrate uaf
tc class add dev lo classid 1:1 drr
step3. a class for nesting
tc class add dev lo classid 1:2 drr
step4. a class to graft qdisc to
tc class add dev lo classid 1:3 drr
step5.
tc qdisc add dev lo parent 1:1 handle 2:0 plug limit 1024
step6.
tc qdisc add dev lo parent 1:2 handle 3:0 drr
step7.
tc class add dev lo classid 3:1 drr
step 8.
tc qdisc add dev lo parent 3:1 handle 4:0 pfifo
step 9. Display the class/qdisc layout
tc class ls dev lo
class drr 1:1 root leaf 2: quantum 64Kb
class drr 1:2 root leaf 3: quantum 64Kb
class drr 3:1 root leaf 4: quantum 64Kb
tc qdisc ls
qdisc drr 1: dev lo root refcnt 2
qdisc plug 2: dev lo parent 1:1
qdisc pfifo 4: dev lo parent 3:1 limit 1000p
qdisc drr 3: dev lo parent 1:2
step10. trigger the bug <=== prevented by this patch
tc qdisc replace dev lo parent 1:3 handle 4:0
step 11. Redisplay again the qdiscs/classes
tc class ls dev lo
class drr 1:1 root leaf 2: quantum 64Kb
class drr 1:2 root leaf 3: quantum 64Kb
class drr 1:3 root leaf 4: quantum 64Kb
class drr 3:1 root leaf 4: quantum 64Kb
tc qdisc ls
qdisc drr 1: dev lo root refcnt 2
qdisc plug 2: dev lo parent 1:1
qdisc pfifo 4: dev lo parent 3:1 refcnt 2 limit 1000p
qdisc drr 3: dev lo parent 1:2
Observe that a) parent for 4:0 does not change despite the replace request.
There can only be one parent. b) refcount has gone up by two for 4:0 and
c) both class 1:3 and 3:1 are pointing to it.
Step 12. send one packet to plug
echo "" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10001))
step13. send one packet to the grafted fifo
echo "" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10003))
step14. lets trigger the uaf
tc class delete dev lo classid 1:3
tc class delete dev lo classid 1:1
The semantics of "replace" is for a del/add _on the same node_ and not
a delete from one node(3:1) and add to another node (1:3) as in step10.
While we could "fix" with a more complex approach there could be
consequences to expectations so the patch takes the preventive approach of
"disallow such config".
Joint work with Lion Ackermann <nnamrec@gmail.com>

Summary
In the Linux kernel, the following vulnerability has been resolved:
sch_htb: make htb_qlen_notify() idempotent
htb_qlen_notify() always deactivates the HTB class and in fact could
trigger a warning if it is already deactivated. Therefore, it is not
idempotent and not friendly to its callers, like fq_codel_dequeue().
Let's make it idempotent to ease qdisc_tree_reduce_backlog() callers'
life.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla4xxx: Prevent a potential error pointer dereference
The qla4xxx_get_ep_fwdb() function is supposed to return NULL on error,
but qla4xxx_ep_connect() returns error pointers. Propagating the error
pointers will lead to an Oops in the caller, so change the error pointers
to NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: af_can: fix NULL pointer dereference in can_rx_register()
It causes NULL pointer dereference when testing as following:
(a) use syscall(__NR_socket, 0x10ul, 3ul, 0) to create netlink socket.
(b) use syscall(__NR_sendmsg, ...) to create bond link device and vxcan
link device, and bind vxcan device to bond device (can also use
ifenslave command to bind vxcan device to bond device).
(c) use syscall(__NR_socket, 0x1dul, 3ul, 1) to create CAN socket.
(d) use syscall(__NR_bind, ...) to bind the bond device to CAN socket.
The bond device invokes the can-raw protocol registration interface to
receive CAN packets. However, ml_priv is not allocated to the dev,
dev_rcv_lists is assigned to NULL in can_rx_register(). In this case,
it will occur the NULL pointer dereference issue.
The following is the stack information:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: fix Rx page leak on multi-buffer frames
The ice_put_rx_mbuf() function handles calling ice_put_rx_buf() for each
buffer in the current frame. This function was introduced as part of
handling multi-buffer XDP support in the ice driver.
It works by iterating over the buffers from first_desc up to 1 plus the
total number of fragments in the frame, cached from before the XDP program
was executed.
If the hardware posts a descriptor with a size of 0, the logic used in
ice_put_rx_mbuf() breaks. Such descriptors get skipped and don't get added
as fragments in ice_add_xdp_frag. Since the buffer isn't counted as a
fragment, we do not iterate over it in ice_put_rx_mbuf(), and thus we don't
call ice_put_rx_buf().
Because we don't call ice_put_rx_buf(), we don't attempt to re-use the
page or free it. This leaves a stale page in the ring, as we don't
increment next_to_alloc.
The ice_reuse_rx_page() assumes that the next_to_alloc has been incremented
properly, and that it always points to a buffer with a NULL page. Since
this function doesn't check, it will happily recycle a page over the top
of the next_to_alloc buffer, losing track of the old page.
Note that this leak only occurs for multi-buffer frames. The
ice_put_rx_mbuf() function always handles at least one buffer, so a
single-buffer frame will always get handled correctly. It is not clear
precisely why the hardware hands us descriptors with a size of 0 sometimes,
but it happens somewhat regularly with "jumbo frames" used by 9K MTU.
To fix ice_put_rx_mbuf(), we need to make sure to call ice_put_rx_buf() on
all buffers between first_desc and next_to_clean. Borrow the logic of a
similar function in i40e used for this same purpose. Use the same logic
also in ice_get_pgcnts().
Instead of iterating over just the number of fragments, use a loop which
iterates until the current index reaches to the next_to_clean element just
past the current frame. Unlike i40e, the ice_put_rx_mbuf() function does
call ice_put_rx_buf() on the last buffer of the frame indicating the end of
packet.
For non-linear (multi-buffer) frames, we need to take care when adjusting
the pagecnt_bias. An XDP program might release fragments from the tail of
the frame, in which case that fragment page is already released. Only
update the pagecnt_bias for the first descriptor and fragments still
remaining post-XDP program. Take care to only access the shared info for
fragmented buffers, as this avoids a significant cache miss.
The xdp_xmit value only needs to be updated if an XDP program is run, and
only once per packet. Drop the xdp_xmit pointer argument from
ice_put_rx_mbuf(). Instead, set xdp_xmit in the ice_clean_rx_irq() function
directly. This avoids needing to pass the argument and avoids an extra
bit-wise OR for each buffer in the frame.
Move the increment of the ntc local variable to ensure its updated *before*
all calls to ice_get_pgcnts() or ice_put_rx_mbuf(), as the loop logic
requires the index of the element just after the current frame.
Now that we use an index pointer in the ring to identify the packet, we no
longer need to track or cache the number of fragments in the rx_ring.

"value": "AV:N - The vulnerable code is the ice NIC\u0027s Rx completion path (`ice_clean_rx_irq`), reached by every inbound Ethernet frame before any protocol demux, socket lookup or firewall filtering, so the attacker only needs to send multi-buffer (\u003e3072 byte) frames at the host. Jumbo MTU is the default on cloud VPC networking (AWS 9001, GCP 8896) and datacenter storage fabrics where such frames are routed across L3, so the trigger is remote, not merely link-local.\nAC:L - The attacker simply floods large frames; Intel documents the zero-size-descriptor condition as occurring \"somewhat regularly\" with 9K MTU, so at volume the leak and the mis-recycled buffer are hit reliably, with no race to win and no memory-layout dependency the attacker cannot influence. Jumbo MTU is a mainstream deployment configuration rather than a rare kernel build option.\nPR:N - Descriptor processing happens in NAPI context before any credential, socket, or netfilter check, so packets to closed ports or packets that would be dropped by the firewall still traverse the buggy code. No account, capability, or session on the target is required.\nUI:N - The bug triggers purely on packet reception by the driver; no local user or administrator has to open, mount, or interact with anything. The victim only needs the interface to be up.\nS:U - The leaked pages, the mis-posted Rx buffers, and the corrupted page refcounts all live in kernel memory managed by the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The unreleased buffer keeps its `page_offset` on the half of the page still owned by an in-flight skb and is re-posted to hardware by `ice_alloc_rx_bufs()`, so a stack-owned buffer \u2014 potentially one mapped into userspace by TCP receive zerocopy \u2014 is simultaneously used as a DMA target for later packets, aliasing data across unrelated flows and tenants. The `pagecnt_bias` over-increment can additionally free a page still referenced by an skb, giving a use-after-free that exposes freed-page contents.\nI:H - Hardware DMAs attacker-controlled packet data directly over payload of skbs already queued in the network stack, silently corrupting data delivered to applications, and the same buffer is handed to the stack twice. The refcount underflow path frees a live page, yielding a page-level use-after-free that is a classic write primitive via heap reuse.\nA:H - Every occurrence permanently leaks a page together with its DMA/IOVA mapping, and the leak is unbounded and driven purely by remote traffic volume \u2014 the reporter observed production hosts steadily losing memory until OOM. The associated buffer aliasing and page refcount underflow also produce corruption and crashes rather than mere degradation."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipvs: Defer ip_vs_ftp unregister during netns cleanup
On the netns cleanup path, __ip_vs_ftp_exit() may unregister ip_vs_ftp
before connections with valid cp->app pointers are flushed, leading to a
use-after-free.
Fix this by introducing a global `exiting_module` flag, set to true in
ip_vs_ftp_exit() before unregistering the pernet subsystem. In
__ip_vs_ftp_exit(), skip ip_vs_ftp unregister if called during netns
cleanup (when exiting_module is false) and defer it to
__ip_vs_cleanup_batch(), which unregisters all apps after all connections
are flushed. If called during module exit, unregister ip_vs_ftp
immediately.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/radeon: fix potential buffer overflow in ni_set_mc_special_registers()
The last case label can write two buffers 'mc_reg_address[j]' and
'mc_data[j]' with 'j' offset equal to SMC_NISLANDS_MC_REGISTER_ARRAY_SIZE
since there are no checks for this value in both case labels after the
last 'j++'.
Instead of changing '>' to '>=' there, add the bounds check at the start
of the second 'case' (the first one already has it).
Also, remove redundant last checks for 'j' index bigger than array size.
The expression is always false. Moreover, before or after the patch
'table->last' can be equal to SMC_NISLANDS_MC_REGISTER_ARRAY_SIZE and it
seems it can be a valid value.
Detected using the static analysis tool - Svace.

Summary
In the Linux kernel, the following vulnerability has been resolved:
posix-cpu-timers: Cleanup CPU timers before freeing them during exec
Commit 55e8c8eb2c7b ("posix-cpu-timers: Store a reference to a pid not a
task") started looking up tasks by PID when deleting a CPU timer.
When a non-leader thread calls execve, it will switch PIDs with the leader
process. Then, as it calls exit_itimers, posix_cpu_timer_del cannot find
the task because the timer still points out to the old PID.
That means that armed timers won't be disarmed, that is, they won't be
removed from the timerqueue_list. exit_itimers will still release their
memory, and when that list is later processed, it leads to a
use-after-free.
Clean up the timers from the de-threaded task before freeing them. This
prevents a reported use-after-free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: add handling for RAID1C23/DUP to btrfs_reduce_alloc_profile
Callers of `btrfs_reduce_alloc_profile` expect it to return exactly
one allocation profile flag, and failing to do so may ultimately
result in a WARN_ON and remount-ro when allocating new blocks, like
the below transaction abort on 6.1.
`btrfs_reduce_alloc_profile` has two ways of determining the profile,
first it checks if a conversion balance is currently running and
uses the profile we're converting to. If no balance is currently
running, it returns the max-redundancy profile which at least one
block in the selected block group has.
This works by simply checking each known allocation profile bit in
redundancy order. However, `btrfs_reduce_alloc_profile` has not been
updated as new flags have been added - first with the `DUP` profile
and later with the RAID1C34 profiles.
Because of the way it checks, if we have blocks with different
profiles and at least one is known, that profile will be selected.
However, if none are known we may return a flag set with multiple
allocation profiles set.
This is currently only possible when a balance from one of the three
unhandled profiles to another of the unhandled profiles is canceled
after allocating at least one block using the new profile.
In that case, a transaction abort like the below will occur and the
filesystem will need to be mounted with -o skip_balance to get it
mounted rw again (but the balance cannot be resumed without a
similar abort).

If no balance is currently\nrunning, it returns the max-redundancy profile which at least one\nblock in the selected block group has.\n\nThis works by simply checking each known allocation profile bit in\nredundancy order. However, `btrfs_reduce_alloc_profile` has not been\nupdated as new flags have been added - first with the `DUP` profile\nand later with the RAID1C34 profiles.\n\nBecause of the way it checks, if we have blocks with different\nprofiles and at least one is known, that profile will be selected.\nHowever, if none are known we may return a flag set with multiple\nallocation profiles set.\n\nThis is currently only possible when a balance from one of the three\nunhandled profiles to another of the unhandled profiles is canceled\nafter allocating at least one block using the new profile.\n\nIn that case, a transaction abort like the below will occur and the\nfilesystem will need to be mounted with -o skip_balance to get it\nmounted rw again (but the balance cannot be resumed without a\nsimilar abort).\n\n [770.648] ------------[ cut here ]------------\n [770.648] BTRFS: Transaction aborted (error -22)\n [770.648] WARNING: CPU: 43 PID: 1159593 at fs/btrfs/extent-tree.c:4122 find_free_extent+0x1d94/0x1e00 [btrfs]\n [770.648] CPU: 43 PID: 1159593 Comm: btrfs Tainted: G W 6.1.0-0.deb11.7-powerpc64le #1 Debian 6.1.20-2~bpo11+1a~test\n [770.648] Hardware name: T2P9D01 REV 1.00 POWER9 0x4e1202 opal:skiboot-bc106a0 PowerNV\n [770.648] NIP: c00800000f6784fc LR: c00800000f6784f8 CTR: c000000000d746c0\n [770.648] REGS: c000200089afe9a0 TRAP: 0700 Tainted: G W (6.1.0-0.deb11.7-powerpc64le Debian 6.1.20-2~bpo11+1a~test)\n [770.648] MSR: 9000000002029033 \u003cSF,HV,VEC,EE,ME,IR,DR,RI,LE\u003e CR: 28848282 XER: 20040000\n [770.648] CFAR: c000000000135110 IRQMASK: 0\n\t GPR00: c00800000f6784f8 c000200089afec40 c00800000f7ea800 0000000000000026\n\t GPR04: 00000001004820c2 c000200089afea00 c000200089afe9f8 0000000000000027\n\t GPR08: c000200ffbfe7f98 c000000002127f90 ffffffffffffffd8 0000000026d6a6e8\n\t GPR12: 0000000028848282 c000200fff7f3800 5deadbeef0000122 c00000002269d000\n\t GPR16: c0002008c7797c40 c000200089afef17 0000000000000000 0000000000000000\n\t GPR20: 0000000000000000 0000000000000001 c000200008bc5a98 0000000000000001\n\t GPR24: 0000000000000000 c0000003c73088d0 c000200089afef17 c000000016d3a800\n\t GPR28: c0000003c7308800 c00000002269d000 ffffffffffffffea 0000000000000001\n [770.648] NIP [c00800000f6784fc] find_free_extent+0x1d94/0x1e00 [btrfs]\n [770.648] LR [c00800000f6784f8] find_free_extent+0x1d90/0x1e00 [btrfs]\n [770.648] Call Trace:\n [770.648] [c000200089afec40] [c00800000f6784f8] find_free_extent+0x1d90/0x1e00 [btrfs] (unreliable)\n [770.648] [c000200089afed30] [c00800000f681398] btrfs_reserve_extent+0x1a0/0x2f0 [btrfs]\n [770.648] [c000200089afeea0] [c00800000f681bf0] btrfs_alloc_tree_block+0x108/0x670 [btrfs]\n [770.648] [c000200089afeff0] [c00800000f66bd68] __btrfs_cow_block+0x170/0x850 [btrfs]\n [770.648] [c000200089aff100] [c00800000f66c58c] btrfs_cow_block+0x144/0x288 [btrfs]\n [770.648] [c000200089aff1b0] [c00800000f67113c] btrfs_search_slot+0x6b4/0xcb0 [btrfs]\n [770.648] [c000200089aff2a0] [c00800000f679f60] lookup_inline_extent_backref+0x128/0x7c0 [btrfs]\n [770.648] [c000200089aff3b0] [c00800000f67b338] lookup_extent_backref+0x70/0x190 [btrfs]\n [770.648] [c000200089aff470] [c00800000f67b54c] __btrfs_free_extent+0xf4/0x1490 [btrfs]\n [770.648] [\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix use-after-free of new block group that became unused
If a task creates a new block group and that block group becomes unused
before we finish its creation, at btrfs_create_pending_block_groups(),
then when btrfs_mark_bg_unused() is called against the block group, we
assume that the block group is currently in the list of block groups to
reclaim, and we move it out of the list of new block groups and into the
list of unused block groups. This has two consequences:
1) We move it out of the list of new block groups associated to the
current transaction. So the block group creation is not finished and
if we attempt to delete the bg because it's unused, we will not find
the block group item in the extent tree (or the new block group tree),
its device extent items in the device tree etc, resulting in the
deletion to fail due to the missing items;
2) We don't increment the reference count on the block group when we
move it to the list of unused block groups, because we assumed the
block group was on the list of block groups to reclaim, and in that
case it already has the correct reference count. However the block
group was on the list of new block groups, in which case no extra
reference was taken because it's local to the current task. This
later results in doing an extra reference count decrement when
removing the block group from the unused list, eventually leading the
reference count to 0.
This second case was caught when running generic/297 from fstests, which
produced the following assertion failure and stack trace:

This\n later results in doing an extra reference count decrement when\n removing the block group from the unused list, eventually leading the\n reference count to 0.\n\nThis second case was caught when running generic/297 from fstests, which\nproduced the following assertion failure and stack trace:\n\n [589.559] assertion failed: refcount_read(\u0026block_group-\u003erefs) == 1, in fs/btrfs/block-group.c:4299\n [589.559] ------------[ cut here ]------------\n [589.559] kernel BUG at fs/btrfs/block-group.c:4299!\n [589.560] invalid opcode: 0000 [#1] PREEMPT SMP PTI\n [589.560] CPU: 8 PID: 2819134 Comm: umount Tainted: G W 6.4.0-rc6-btrfs-next-134+ #1\n [589.560] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.2-0-gea1b7a073390-prebuilt.qemu.org 04/01/2014\n [589.560] RIP: 0010:btrfs_free_block_groups+0x449/0x4a0 [btrfs]\n [589.561] Code: 68 62 da c0 (...)\n [589.561] RSP: 0018:ffffa55a8c3b3d98 EFLAGS: 00010246\n [589.561] RAX: 0000000000000058 RBX: ffff8f030d7f2000 RCX: 0000000000000000\n [589.562] RDX: 0000000000000000 RSI: ffffffff953f0878 RDI: 00000000ffffffff\n [589.562] RBP: ffff8f030d7f2088 R08: 0000000000000000 R09: ffffa55a8c3b3c50\n [589.562] R10: 0000000000000001 R11: 0000000000000001 R12: ffff8f05850b4c00\n [589.562] R13: ffff8f030d7f2090 R14: ffff8f05850b4cd8 R15: dead000000000100\n [589.563] FS: 00007f497fd2e840(0000) GS:ffff8f09dfc00000(0000) knlGS:0000000000000000\n [589.563] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n [589.563] CR2: 00007f497ff8ec10 CR3: 0000000271472006 CR4: 0000000000370ee0\n [589.563] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n [589.564] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n [589.564] Call Trace:\n [589.564] \u003cTASK\u003e\n [589.565] ? __die_body+0x1b/0x60\n [589.565] ? die+0x39/0x60\n [589.565] ? do_trap+0xeb/0x110\n [589.565] ? btrfs_free_block_groups+0x449/0x4a0 [btrfs]\n [589.566] ? do_error_trap+0x6a/0x90\n [589.566] ? btrfs_free_block_groups+0x449/0x4a0 [btrfs]\n [589.566] ? exc_invalid_op+0x4e/0x70\n [589.566] ? btrfs_free_block_groups+0x449/0x4a0 [btrfs]\n [589.567] ? asm_exc_invalid_op+0x16/0x20\n [589.567] ? btrfs_free_block_groups+0x449/0x4a0 [btrfs]\n [589.567] ? btrfs_free_block_groups+0x449/0x4a0 [btrfs]\n [589.567] close_ctree+0x35d/0x560 [btrfs]\n [589.568] ? fsnotify_sb_delete+0x13e/0x1d0\n [589.568] ? dispose_list+0x3a/0x50\n [589.568] ? evict_inodes+0x151/0x1a0\n [589.568] generic_shutdown_super+0x73/0x1a0\n [589.569] kill_anon_super+0x14/0x30\n [589.569] btrfs_kill_super+0x12/0x20 [btrfs]\n [589.569] deactivate_locked\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
ax25: properly unshare skbs in ax25_kiss_rcv()
Bernard Pidoux reported a regression apparently caused by commit
c353e8983e0d ("net: introduce per netns packet chains").
skb->dev becomes NULL and we crash in __netif_receive_skb_core().
Before above commit, different kind of bugs or corruptions could happen
without a major crash.
But the root cause is that ax25_kiss_rcv() can queue/mangle input skb
without checking if this skb is shared or not.
Many thanks to Bernard Pidoux for his help, diagnosis and tests.
We had a similar issue years ago fixed with commit 7aaed57c5c28
("phonet: properly unshare skbs in phonet_rcv()").

AX.25 frames are not IP-routable in-kernel, matching the AV:A precedent set for the sibling netrom frame-receive CVE-2026-23098.\nAC:L - Every received AX.25 frame reaches the unshared-skb path; no crafting, timing window, or memory-layout grooming is required of the attacker, who fully controls frame content and rate. The only precondition \u2014 an AF_PACKET tap on ETH_P_AX25 placed after ptype_base \u2014 is the standard axlisten/mheardd monitoring setup present on ordinary AX.25 stations, which is how the bug was reported in the field.\nPR:N - AX.25 is entirely unauthenticated and ax25_kiss_rcv() runs on every frame before any socket, callsign, or connection state check. An attacker simply transmits on the channel or sends BPQ frames on the LAN with no credentials on the target system.\nUI:N - The frame is processed in softirq context by the receive path as soon as it arrives; no local user or administrator has to open, read, or otherwise interact with anything.\nS:U - The corruption is confined to kernel skb/socket-queue structures within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The shared skb is mutated (skb_pull, header resets, skb-\u003edev/protocol rewrite) and re-queued while another consumer still reads it, so packet-socket consumers receive mis-parsed buffers, and the resulting use-after-free/list corruption of sk_buff objects yields a read primitive over freed kernel memory.\nI:H - Queueing a shared skb simultaneously onto the backlog, an AX.25 socket receive queue, and ax25-\u003efrag_queue produces sk_buff list corruption and double free, and skb_orphan() on a shared skb corrupts another socket\u0027s rmem accounting \u2014 classic heap-corruption primitives leverageable for arbitrary write and control-flow hijack.\nA:H - The reporter reproduced a hard kernel crash from a NULL skb-\u003edev dereference in __netif_receive_skb_core(), and the underlying skb double-queue/double-free reliably panics the machine; the attacker can repeat it with every frame transmitted."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: usb: smsc75xx: Limit packet length to skb->len
Packet length retrieved from skb data may be larger than
the actual socket buffer length (up to 9026 bytes). In such
case the cloned skb passed up the network stack will leak
kernel memory contents.

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64/sme: Set new vector length before reallocating
As part of fixing the allocation of the buffer for SVE state when changing
SME vector length we introduced an immediate reallocation of the SVE state,
this is also done when changing the SVE vector length for consistency.
Unfortunately this reallocation is done prior to writing the new vector
length to the task struct, meaning the allocation is done with the old
vector length and can lead to memory corruption due to an undersized buffer
being used.
Move the update of the vector length before the allocation to ensure that
the new vector length is taken into account.
For some reason this isn't triggering any problems when running tests on
the arm64 fixes branch (even after repeated tries) but is triggering
issues very often after merge into mainline.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/iucv: Fix size of interrupt data
iucv_irq_data needs to be 4 bytes larger.
These bytes are not used by the iucv module, but written by
the z/VM hypervisor in case a CPU is deconfigured.
Reported as:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: pfr_update: Fix the driver update version check
The security-version-number check should be used rather
than the runtime version check for driver updates.
Otherwise, the firmware update would fail when the update binary had
a lower runtime version number than the current one.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/irdma: Fix a window for use-after-free
During a destroy CQ an interrupt may cause processing of a CQE after CQ
resources are freed by irdma_cq_free_rsrc(). Fix this by moving the call
to irdma_cq_free_rsrc() after the irdma_sc_cleanup_ceqes(), which is
called under the cq_lock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
kcm: fix strp_init() order and cleanup
strp_init() is called just a few lines above this csk->sk_user_data
check, it also initializes strp->work etc., therefore, it is
unnecessary to call strp_done() to cancel the freshly initialized
work.
And if sk_user_data is already used by KCM, psock->strp should not be
touched, particularly strp->work state, so we need to move strp_init()
after the csk->sk_user_data check.
This also makes a lockdep warning reported by syzbot go away.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: kprobe: Fix memory leak in test_gen_kprobe/kretprobe_cmd()
test_gen_kprobe_cmd() only free buf in fail path, hence buf will leak
when there is no failure. Move kfree(buf) from fail path to common path
to prevent the memleak. The same reason and solution in
test_gen_kretprobe_cmd().

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: cdns3 fix use-after-free at workaround 2
BUG: KFENCE: use-after-free read in __list_del_entry_valid+0x10/0xac
cdns3_wa2_remove_old_request()
{
...
kfree(priv_req->request.buf);
cdns3_gadget_ep_free_request(&priv_ep->endpoint, &priv_req->request);
list_del_init(&priv_req->list);
^^^ use after free
...
}
cdns3_gadget_ep_free_request() free the space pointed by priv_req,
but priv_req is used in the following list_del_init().
This patch move list_del_init() before cdns3_gadget_ep_free_request().

Summary
In the Linux kernel, the following vulnerability has been resolved:
xhci: Fix null pointer dereference in remove if xHC has only one roothub
The remove path in xhci platform driver tries to remove and put both main
and shared hcds even if only a main hcd exists (one roothub)
This causes a null pointer dereference in reboot for those controllers.
Check that the shared_hcd exists before trying to remove it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
clocksource/drivers/cadence-ttc: Fix memory leak in ttc_timer_probe
Smatch reports:
drivers/clocksource/timer-cadence-ttc.c:529 ttc_timer_probe()
warn: 'timer_baseaddr' from of_iomap() not released on lines: 498,508,516.
timer_baseaddr may have the problem of not being released after use,
I replaced it with the devm_of_iomap() function and added the clk_put()
function to cleanup the "clk_ce" and "clk_cs".

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfc: st-nci: Fix use after free bug in ndlc_remove due to race condition
This bug influences both st_nci_i2c_remove and st_nci_spi_remove.
Take st_nci_i2c_remove as an example.
In st_nci_i2c_probe, it called ndlc_probe and bound &ndlc->sm_work
with llt_ndlc_sm_work.
When it calls ndlc_recv or timeout handler, it will finally call
schedule_work to start the work.
When we call st_nci_i2c_remove to remove the driver, there
may be a sequence as follows:
Fix it by finishing the work before cleanup in ndlc_remove

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI/ASPM: Disable ASPM on MFD function removal to avoid use-after-free
Struct pcie_link_state->downstream is a pointer to the pci_dev of function
0. Previously we retained that pointer when removing function 0, and
subsequent ASPM policy changes dereferenced it, resulting in a
use-after-free warning from KASAN, e.g.:
# echo 1 > /sys/bus/pci/devices/0000:03:00.0/remove
# echo powersave > /sys/module/pcie_aspm/parameters/policy
BUG: KASAN: slab-use-after-free in pcie_config_aspm_link+0x42d/0x500
Call Trace:
kasan_report+0xae/0xe0
pcie_config_aspm_link+0x42d/0x500
pcie_aspm_set_policy+0x8e/0x1a0
param_attr_store+0x162/0x2c0
module_attr_store+0x3e/0x80
PCIe spec r6.0, sec 7.5.3.7, recommends that software program the same ASPM
Control value in all functions of multi-function devices.
Disable ASPM and free the pcie_link_state when any child function is
removed so we can discard the dangling pcie_link_state->downstream pointer
and maintain the same ASPM Control configuration for all functions.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix error unwind in rxe_create_qp()
In the function rxe_create_qp(), rxe_qp_from_init() is called to
initialize qp, internally things like the spin locks are not setup until
rxe_qp_init_req().
If an error occures before this point then the unwind will call
rxe_cleanup() and eventually to rxe_qp_do_cleanup()/rxe_cleanup_task()
which will oops when trying to access the uninitialized spinlock.
Move the spinlock initializations earlier before any failures.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bus: mhi: host: Detect events pointing to unexpected TREs
When a remote device sends a completion event to the host, it contains a
pointer to the consumed TRE. The host uses this pointer to process all of
the TREs between it and the host's local copy of the ring's read pointer.
This works when processing completion for chained transactions, but can
lead to nasty results if the device sends an event for a single-element
transaction with a read pointer that is multiple elements ahead of the
host's read pointer.
For instance, if the host accesses an event ring while the device is
updating it, the pointer inside of the event might still point to an old
TRE. If the host uses the channel's xfer_cb() to directly free the buffer
pointed to by the TRE, the buffer will be double-freed.
This behavior was observed on an ep that used upstream EP stack without
'commit 6f18d174b73d ("bus: mhi: ep: Update read pointer only after buffer
is written")'. Where the device updated the events ring pointer before
updating the event contents, so it left a window where the host was able to
access the stale data the event pointed to, before the device had the
chance to update them. The usual pattern was that the host received an
event pointing to a TRE that is not immediately after the last processed
one, so it got treated as if it was a chained transaction, processing all
of the TREs in between the two read pointers.
This commit aims to harden the host by ensuring transactions where the
event points to a TRE that isn't local_rp + 1 are chained.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix data corruption after failed write
When buffered write fails to copy data into underlying page cache page,
ocfs2_write_end_nolock() just zeroes out and dirties the page. This can
leave dirty page beyond EOF and if page writeback tries to write this page
before write succeeds and expands i_size, page gets into inconsistent
state where page dirty bit is clear but buffer dirty bits stay set
resulting in page data never getting written and so data copied to the
page is lost. Fix the problem by invalidating page beyond EOF after
failed write.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs: udf: fix OOB read in lengthAllocDescs handling
When parsing Allocation Extent Descriptor, lengthAllocDescs comes from
on-disk data and must be validated against the block size. Crafted or
corrupted images may set lengthAllocDescs so that the total descriptor
length (sizeof(allocExtDesc) + lengthAllocDescs) exceeds the buffer,
leading udf_update_tag() to call crc_itu_t() on out-of-bounds memory and
trigger a KASAN use-after-free read.
BUG: KASAN: use-after-free in crc_itu_t+0x1d5/0x2b0 lib/crc-itu-t.c:60

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: bpf: Only mitigate cBPF programs loaded by unprivileged users
Support for eBPF programs loaded by unprivileged users is typically
disabled. This means only cBPF programs need to be mitigated for BHB.
In addition, only mitigate cBPF programs that were loaded by an
unprivileged user. Privileged users can also load the same program
via eBPF, making the mitigation pointless.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Fix possible crash in bnxt_hwrm_set_coal()
During the error recovery sequence, the rtnl_lock is not held for the
entire duration and some datastructures may be freed during the sequence.
Check for the BNXT_STATE_OPEN flag instead of netif_running() to ensure
that the device is fully operational before proceeding to reconfigure
the coalescing settings.
This will fix a possible crash like this:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ntfs: fix use-after-free in ntfs_attr_find()
Patch series "ntfs: fix bugs about Attribute", v2.
This patchset fixes three bugs relative to Attribute in record:
Patch 1 adds a sanity check to ensure that, attrs_offset field in first
mft record loading from disk is within bounds.
Patch 2 moves the ATTR_RECORD's bounds checking earlier, to avoid
dereferencing ATTR_RECORD before checking this ATTR_RECORD is within
bounds.
Patch 3 adds an overflow checking to avoid possible forever loop in
ntfs_attr_find().
Without patch 1 and patch 2, the kernel triggersa KASAN use-after-free
detection as reported by Syzkaller.
Although one of patch 1 or patch 2 can fix this, we still need both of
them. Because patch 1 fixes the root cause, and patch 2 not only fixes
the direct cause, but also fixes the potential out-of-bounds bug.
This patch (of 3):
Syzkaller reported use-after-free read as follows:

==================================================================
Kernel will loads $MFT/$DATA's first mft record in
ntfs_read_inode_mount().
Yet the problem is that after loading, kernel doesn't check whether
attrs_offset field is a valid value.
To be more specific, if attrs_offset field is larger than bytes_allocated
field, then it may trigger the out-of-bounds read bug(reported as
use-after-free bug) in ntfs_attr_find(), when kernel tries to access the
corresponding mft record's attribute.
This patch solves it by adding the sanity check between attrs_offset field
and bytes_allocated field, after loading the first mft record.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: multitouch: Correct devm device reference for hidinput input_dev name
Reference the HID device rather than the input device for the devm
allocation of the input_dev name. Referencing the input_dev would lead to a
use-after-free when the input_dev was unregistered and subsequently fires a
uevent that depends on the name. At the point of firing the uevent, the
name would be freed by devres management.
Use devm_kasprintf to simplify the logic for allocating memory and
formatting the input_dev name string.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: x86: s2idle: Catch multiple ACPI_TYPE_PACKAGE objects
If a badly constructed firmware includes multiple `ACPI_TYPE_PACKAGE`
objects while evaluating the AMD LPS0 _DSM, there will be a memory
leak. Explicitly guard against this.

Bluetooth: L2CAP: Fix memory leak in vhci_write

====================================
HCI core will uses hci_rx_work() to process frame, which is queued to
the hdev->rx_q tail in hci_recv_frame() by HCI driver.
Yet the problem is that, HCI core may not free the skb after handling
ACL data packets. To be more specific, when start fragment does not
contain the L2CAP length, HCI core just copies skb into conn->rx_skb and
finishes frame process in l2cap_recv_acldata(), without freeing the skb,
which triggers the above memory leak.
This patch solves it by releasing the relative skb, after processing
the above case in l2cap_recv_acldata().

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: mceusb: Use new usb_control_msg_*() routines
Automatic kernel fuzzing led to a WARN about invalid pipe direction in
the mceusb driver:

mceusb_dev_probe+0x258e/0x33f0 drivers/media/rc/mceusb.c:1807
The reason for the warning is clear enough; the driver sends an
unusual read request on endpoint 0 but does not set the USB_DIR_IN bit
in the bRequestType field.
More importantly, the whole situation can be avoided and the driver
simplified by converting it over to the relatively new
usb_control_msg_recv() and usb_control_msg_send() routines. That's
what this fix does.

Summary
In the Linux kernel, the following vulnerability has been resolved:
shmem: use ramfs_kill_sb() for kill_sb method of ramfs-based tmpfs
As the ramfs-based tmpfs uses ramfs_init_fs_context() for the
init_fs_context method, which allocates fc->s_fs_info, use ramfs_kill_sb()
to free it and avoid a memory leak.

In the cpu_map_update_elem flow, when kthread_stop is called before
calling the threadfn of rcpu->kthread, since the KTHREAD_SHOULD_STOP bit
of kthread has been set by kthread_stop, the threadfn of rcpu->kthread
will never be executed, and rcpu->refcnt will never be 0, which will
lead to the allocated rcpu, rcpu->queue and rcpu->queue->queue cannot be
released.
Calling kthread_stop before executing kthread's threadfn will return
-EINTR. We can complete the release of memory resources in this state.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: SVM: Don't BUG if userspace injects an interrupt with GIF=0
Don't BUG/WARN on interrupt injection due to GIF being cleared,
since it's trivial for userspace to force the situation via
KVM_SET_VCPU_EVENTS (even if having at least a WARN there would be correct
for KVM internally generated injections).

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: hid-ntrig: fix unable to handle page fault in ntrig_report_version()
in ntrig_report_version(), hdev parameter passed from hid_probe().
sending descriptor to /dev/uhid can make hdev->dev.parent->parent to null
if hdev->dev.parent->parent is null, usb_dev has
invalid address(0xffffffffffffff58) that hid_to_usb_dev(hdev) returned
when usb_rcvctrlpipe() use usb_dev,it trigger
page fault error for address(0xffffffffffffff58)
add null check logic to ntrig_report_version()
before calling hid_to_usb_dev()

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: hi846: fix usage of pm_runtime_get_if_in_use()
pm_runtime_get_if_in_use() does not only return nonzero values when
the device is in use, it can return a negative errno too.
And especially during resuming from system suspend, when runtime pm
is not yet up again, -EAGAIN is being returned, so the subsequent
pm_runtime_put() call results in a refcount underflow.
Fix system-resume by handling -EAGAIN of pm_runtime_get_if_in_use().

In the Linux kernel, the following vulnerability has been resolved:
s390: fix double free of GS and RI CBs on fork() failure
The pointers for guarded storage and runtime instrumentation control
blocks are stored in the thread_struct of the associated task. These
pointers are initially copied on fork() via arch_dup_task_struct()
and then cleared via copy_thread() before fork() returns. If fork()
happens to fail after the initial task dup and before copy_thread(),
the newly allocated task and associated thread_struct memory are
freed via free_task() -> arch_release_task_struct(). This results in
a double free of the guarded storage and runtime info structs
because the fields in the failed task still refer to memory
associated with the source task.
This problem can manifest as a BUG_ON() in set_freepointer() (with
CONFIG_SLAB_FREELIST_HARDENED enabled) or KASAN splat (if enabled)
when running trinity syscall fuzz tests on s390x. To avoid this
problem, clear the associated pointer fields in
arch_dup_task_struct() immediately after the new task is copied.
Note that the RI flag is still cleared in copy_thread() because it
resides in thread stack memory and that is where stack info is
copied.

Summary
In the Linux kernel, the following vulnerability has been resolved:
jfs: truncate good inode pages when hard link is 0
The fileset value of the inode copy from the disk by the reproducer is
AGGR_RESERVED_I. When executing evict, its hard link number is 0, so its
inode pages are not truncated. This causes the bugon to be triggered when
executing clear_inode() because nrpages is greater than 0.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPICA: Add AML_NO_OPERAND_RESOLVE flag to Timer
ACPICA commit 90310989a0790032f5a0140741ff09b545af4bc5
According to the ACPI specification 19.6.134, no argument is required to be passed for ASL Timer instruction. For taking care of no argument, AML_NO_OPERAND_RESOLVE flag is added to ASL Timer instruction opcode.
When ASL timer instruction interpreted by ACPI interpreter, getting error. After adding AML_NO_OPERAND_RESOLVE flag to ASL Timer instruction opcode, issue is not observed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
remoteproc: k3-r5: Fix refcount leak in k3_r5_cluster_of_init
Every iteration of for_each_available_child_of_node() decrements
the reference count of the previous node.
When breaking early from a for_each_available_child_of_node() loop,
we need to explicitly call of_node_put() on the child node.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
capabilities: fix potential memleak on error path from vfs_getxattr_alloc()
In cap_inode_getsecurity(), we will use vfs_getxattr_alloc() to
complete the memory allocation of tmpbuf, if we have completed
the memory allocation of tmpbuf, but failed to call handler->get(...),
there will be a memleak in below logic:
|-- ret = (int)vfs_getxattr_alloc(mnt_userns, ...)
| /* ^^^ alloc for tmpbuf */
|-- value = krealloc(*xattr_value, error + 1, flags)
| /* ^^^ alloc memory */
|-- error = handler->get(handler, ...)
| /* error! */
|-- *xattr_value = value
| /* xattr_value is &tmpbuf (memory leak!) */
So we will try to free(tmpbuf) after vfs_getxattr_alloc() fails to fix it.
[PM: subject line and backtrace tweaks]

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/damon/core: initialize damo_filter->list from damos_new_filter()
damos_new_filter() is not initializing the list field of newly allocated
filter object. However, DAMON sysfs interface and DAMON_RECLAIM are not
initializing it after calling damos_new_filter(). As a result, accessing
uninitialized memory is possible. Actually, adding multiple DAMOS filters
via DAMON sysfs interface caused NULL pointer dereferencing. Initialize
the field just after the allocation from damos_new_filter().

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix race in do_task() when draining
When do_task() exhausts its iteration budget (!ret), it sets the state
to TASK_STATE_IDLE to reschedule, without a secondary check on the
current task->state. This can overwrite the TASK_STATE_DRAINING state
set by a concurrent call to rxe_cleanup_task() or rxe_disable_task().
While state changes are protected by a spinlock, both rxe_cleanup_task()
and rxe_disable_task() release the lock while waiting for the task to
finish draining in the while(!is_done(task)) loop. The race occurs if
do_task() hits its iteration limit and acquires the lock in this window.
The cleanup logic may then proceed while the task incorrectly
reschedules itself, leading to a potential use-after-free.
This bug was introduced during the migration from tasklets to workqueues,
where the special handling for the draining case was lost.
Fix this by restoring the original pre-migration behavior. If the state is
TASK_STATE_DRAINING when iterations are exhausted, set cont to 1 to
force a new loop iteration. This allows the task to finish its work, so
that a subsequent iteration can reach the switch statement and correctly
transition the state to TASK_STATE_DRAINED, stopping the task as intended.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFS: Fix a potential data corruption
We must ensure that the subrequests are joined back into the head before
we can retransmit a request. If the head was not on the commit lists,
because the server wrote it synchronously, we still need to add it back
to the retransmission list.
Add a call that mirrors the effect of nfs_cancel_remove_inode() for
O_DIRECT.

A malicious/compromised NFS server or an on-path attacker on unauthenticated AUTH_SYS NFS traffic reaches it over the network with no local access.\nAC:L - All three preconditions are server-controlled and can be produced deterministically and repeatedly: advertise a wsize that forces `__nfs_pageio_add_request()` to split a request into head+subrequest across two RPCs, answer one FILE_SYNC and the other UNSTABLE so only the subrequest lands on the commit list, then return a changed write verifier on COMMIT to force the reschedule.\nPR:N - The attacker is the remote NFS server (or an on-path attacker), which needs no credentials or privileges on the victim client; the vulnerable path runs in the client\u0027s normal write-completion/reschedule machinery.\nUI:N - No victim action is required beyond an already-mounted export carrying an ordinary O_DIRECT workload \u2014 the databases, VM images and backup jobs NFS O_DIRECT exists for. The reschedule runs asynchronously from `nfsiod` with no user involvement.\nS:U - The defect and its consequences are confined to the NFS client within the same kernel security authority; no VM, sandbox, or IOMMU boundary is crossed.\nC:N - Tracing the path shows no out-of-bounds read, no kernel-memory disclosure and no read primitive \u2014 subrequests hold krefs on the head and `nfs_page_group_destroy()`\u0027s deferred teardown prevents any use-after-free. The impact is confined to what gets written back.\nI:H - Retransmitting subrequests without rejoining them to the head means an O_DIRECT write is not faithfully re-driven to stable storage after the server discards its unstable cache, so file contents silently diverge from what the application wrote while `write()` still reports success \u2014 unbounded, undetected corruption of stored data on a shared network filesystem.\nA:L - The un-joined group never collapses, so each attacker-forced reschedule round re-splits requests and grafts more members onto a page-group ring that cannot be reclaimed until the whole dreq dies, degrading memory and lengthening the O(N) ring walks while the write fails to converge. I found no reachable panic, BUG_ON, or hang, so this is degradation rather than a full availability loss."

"value": "AV:L - The only entry point is the local `ioctl(SIOCSIWENCODEEXT)` wireless-extensions path on the ks7010 net_device; no remote or adjacent-network peer data reaches `ks_wlan_set_encode_ext()`. Requires a local process holding an AF_INET/AF_PACKET socket on the host.\nAC:L - Every input to the vulnerable `memcpy` \u2014 `key_len`, the key payload, `alg`, `ext_flags` and the key index \u2014 is supplied directly by the attacker in a single ioctl, with no race to win and no memory layout the attacker cannot groom beforehand. The `SLP_SLEEP` early-return guard is itself settable by the attacker through the driver\u0027s own private ioctl.\nPR:L - `wext_permission_check()` requires CAP_NET_ADMIN, but that is a delegable capability routinely held by non-root network/WiFi management daemons (the wpa_supplicant-style model on the embedded and handheld devices this SDIO driver targets), not full administrative control of the system. Choosing the higher-severity option where the boundary between a confined capability holder and true root is deployment-dependent.\nUI:N - The attacker issues the ioctl directly against an existing ks7010 interface; no victim action, no file to open, nothing to mount. The interface merely has to be present and registered.\nS:U - The overflow corrupts kernel heap adjacent to the net_device private data and stays entirely within the kernel\u0027s own security authority. There is no hypervisor, IOMMU, or sandbox boundary crossed.\nC:H - The oversized copy reads far past the 104-byte `extra` slab allocation, pulling adjacent kernel heap contents into `key-\u003ekey_val`, from where they are shipped to the device via the SME_SET_KEY request. The resulting heap corruption is also leverageable into a general kernel-memory read primitive.\nI:H - An unbounded `__u16` length turns this into an out-of-bounds write of up to ~65471 bytes past a 64-byte buffer inside `netdev_priv()`, with the leading bytes fully attacker-chosen. That is a classic controllable heap overflow suitable for overwriting adjacent objects and hijacking control flow.\nA:H - Overwriting tens of kilobytes of slab memory past `struct wpa_key` reliably destroys neighbouring allocations and slab metadata, producing an oops or panic. Any unsuccessful exploitation attempt still crashes the kernel."

Summary
In the Linux kernel, the following vulnerability has been resolved:
codel: remove sch->q.qlen check before qdisc_tree_reduce_backlog()
After making all ->qlen_notify() callbacks idempotent, now it is safe to
remove the check of qlen!=0 from both fq_codel_dequeue() and
codel_qdisc_dequeue().

The inconsistent active-but-empty class state persists indefinitely, so no race window must be won.\nPR:L - Configuring qdiscs requires CAP_NET_ADMIN, but rtnetlink checks it via sk_ns_capable(sk, net-\u003euser_ns, CAP_NET_ADMIN), which any unprivileged local user obtains inside a `unshare -Urn` user+network namespace. Per kernel scoring guidance, tc/qdisc reachable through user namespaces is Low, not High.\nUI:N - The attacker performs every step \u2014 qdisc setup, traffic generation, and class deletion \u2014 within their own namespace. No victim action or interaction is needed.\nS:U - The corruption is confined to kernel heap objects and scheduler data structures managed by the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed drr_class/qfq_class/hfsc_class remains linked in the parent\u0027s active list and rbtrees; after heap reclaim the attacker controls the object contents and the traversals read kernel pointers back out of it, yielding an arbitrary-read primitive and kernel address disclosure. Per guidance, use-after-free is High.\nI:H - Subsequent list_del/list_add and rb_erase operations write through pointers stored in the freed object, and drr_dequeue()/agg_dequeue() perform an indirect call via cl-\u003eqdisc-\u003eops-\u003epeek() on reclaimed memory, giving a write primitive and control-flow hijack suitable for full privilege escalation.\nA:H - Even without successful exploitation, the dangling class in the active list/rbtree causes list and red-black-tree corruption and dereference of poisoned or freed pointers, producing a kernel oops or panic that can be triggered repeatedly by an unprivileged user."

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/iommu: fix memory leak with using debugfs_lookup()
When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time. To make things simpler, just
call debugfs_lookup_and_remove() instead which handles all of the logic
at once.

This occurs when logical inode resolution takes a tree mod log sequence
number, and then while backref walking hits a rewind on a busy node
which has the following sequence of tree mod log operations (numbers
filled in from a specific example, but they are somewhat arbitrary)
REMOVE_WHILE_FREEING slot 532
REMOVE_WHILE_FREEING slot 531
REMOVE_WHILE_FREEING slot 530
...
REMOVE_WHILE_FREEING slot 0
REMOVE slot 455
REMOVE slot 454
REMOVE slot 453
...
REMOVE slot 0
ADD slot 455
ADD slot 454
ADD slot 453
...
ADD slot 0
MOVE src slot 0 -> dst slot 456 nritems 533
REMOVE slot 455
REMOVE slot 454
REMOVE slot 453
...
REMOVE slot 0
When this sequence gets applied via btrfs_tree_mod_log_rewind, it
allocates a fresh rewind eb, and first inserts the correct key info for
the 533 elements, then overwrites the first 456 of them, then decrements
the count by 456 via the add ops, then rewinds the move by doing a
memmove from 456:988->0:532. We have never written anything past 532,

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: imx: clk-imxrt1050: fix memory leak in imxrt1050_clocks_probe
Use devm_of_iomap() instead of of_iomap() to automatically
handle the unused ioremap region. If any error occurs, regions allocated by
kzalloc() will leak, but using devm_kzalloc() instead will automatically
free the memory using devm_kfree().
Also, fix error handling of hws by adding unregister_hws label, which
unregisters remaining hws when iomap failed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - flush misc workqueue during device shutdown
Repeated loading and unloading of a device specific QAT driver, for
example qat_4xxx, in a tight loop can lead to a crash due to a
use-after-free scenario. This occurs when a power management (PM)
interrupt triggers just before the device-specific driver (e.g.,
qat_4xxx.ko) is unloaded, while the core driver (intel_qat.ko) remains
loaded.
Since the driver uses a shared workqueue (`qat_misc_wq`) across all
devices and owned by intel_qat.ko, a deferred routine from the
device-specific driver may still be pending in the queue. If this
routine executes after the driver is unloaded, it can dereference freed
memory, resulting in a page fault and kernel crash like the following:
BUG: unable to handle page fault for address: ffa000002e50a01c
#PF: supervisor read access in kernel mode
RIP: 0010:pm_bh_handler+0x1d2/0x250 [intel_qat]
Call Trace:
pm_bh_handler+0x1d2/0x250 [intel_qat]
process_one_work+0x171/0x340
worker_thread+0x277/0x3a0
kthread+0xf0/0x120
ret_from_fork+0x2d/0x50
To prevent this, flush the misc workqueue during device shutdown to
ensure that all pending work items are completed before the driver is
unloaded.
Note: This approach may slightly increase shutdown latency if the
workqueue contains jobs from other devices, but it ensures correctness
and stability.

This occurs when a power management (PM)\ninterrupt triggers just before the device-specific driver (e.g.,\nqat_4xxx.ko) is unloaded, while the core driver (intel_qat.ko) remains\nloaded.\n\nSince the driver uses a shared workqueue (`qat_misc_wq`) across all\ndevices and owned by intel_qat.ko, a deferred routine from the\ndevice-specific driver may still be pending in the queue. If this\nroutine executes after the driver is unloaded, it can dereference freed\nmemory, resulting in a page fault and kernel crash like the following:\n\n BUG: unable to handle page fault for address: ffa000002e50a01c\n #PF: supervisor read access in kernel mode\n RIP: 0010:pm_bh_handler+0x1d2/0x250 [intel_qat]\n Call Trace:\n pm_bh_handler+0x1d2/0x250 [intel_qat]\n process_one_work+0x171/0x340\n worker_thread+0x277/0x3a0\n kthread+0xf0/0x120\n ret_from_fork+0x2d/0x50\n\nTo prevent this, flush the misc workqueue during device shutdown to\nensure that all pending work items are completed before the driver is\nunloaded.\n\nNote: This approach may slightly increase shutdown latency if the\nworkqueue contains jobs from other devices, but it ensures correctness\nand stability."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/gma500: Fix null dereference in hdmi teardown
pci_set_drvdata sets the value of pdev->driver_data to NULL,
after which the driver_data obtained from the same dev is
dereferenced in oaktrail_hdmi_i2c_exit, and the i2c_dev is
extracted from it. To prevent this, swap these calls.
Found by Linux Verification Center (linuxtesting.org) with Svacer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfc: fdp: Fix potential memory leak in fdp_nci_send()
fdp_nci_send() will call fdp_nci_i2c_write that will not free skb in
the function. As a result, when fdp_nci_i2c_write() finished, the skb
will memleak. fdp_nci_send() should free skb after fdp_nci_i2c_write()
finished.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xsk: Fix corrupted packets for XDP_SHARED_UMEM
Fix an issue in XDP_SHARED_UMEM mode together with aligned mode where
packets are corrupted for the second and any further sockets bound to
the same umem. In other words, this does not affect the first socket
bound to the umem. The culprit for this bug is that the initialization
of the DMA addresses for the pre-populated xsk buffer pool entries was
not performed for any socket but the first one bound to the umem. Only
the linear array of DMA addresses was populated. Fix this by populating
the DMA addresses in the xsk buffer pool for every socket bound to the
same umem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
macvlan: add forgotten nla_policy for IFLA_MACVLAN_BC_CUTOFF
The previous commit 954d1fa1ac93 ("macvlan: Add netlink attribute for
broadcast cutoff") added one additional attribute named
IFLA_MACVLAN_BC_CUTOFF to allow broadcast cutfoff.
However, it forgot to describe the nla_policy at macvlan_policy
(drivers/net/macvlan.c). Hence, this suppose NLA_S32 (4 bytes) integer
can be faked as empty (0 bytes) by a malicious user, which could leads
to OOB in heap just like CVE-2023-3773.
To fix it, this commit just completes the nla_policy description for
IFLA_MACVLAN_BC_CUTOFF. This enforces the length check and avoids the
potential OOB read.

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: don't allow the same type rq_qos add more than once
In our test of iocost, we encountered some list add/del corruptions of
inner_walk list in ioc_timer_fn.
The reason can be described as follows:
cpu 0 cpu 1
ioc_qos_write ioc_qos_write
ioc = q_to_ioc(queue);
if (!ioc) {
ioc = kzalloc();
ioc = q_to_ioc(queue);
if (!ioc) {
ioc = kzalloc();
...
rq_qos_add(q, rqos);
}
...
rq_qos_add(q, rqos);
...
}
When the io.cost.qos file is written by two cpus concurrently, rq_qos may
be added to one disk twice. In that case, there will be two iocs enabled
and running on one disk. They own different iocgs on their active list. In
the ioc_timer_fn function, because of the iocgs from two iocs have the
same root iocg, the root iocg's walk_list may be overwritten by each other
and this leads to list add/del corruptions in building or destroying the
inner_walk list.
And so far, the blk-rq-qos framework works in case that one instance for
one type rq_qos per queue by default. This patch make this explicit and
also fix the crash above.

Summary
In the Linux kernel, the following vulnerability has been resolved:
loop: Fix use-after-free issues
do_req_filebacked() calls blk_mq_complete_request() synchronously or
asynchronously when using asynchronous I/O unless memory allocation fails.
Hence, modify loop_handle_cmd() such that it does not dereference 'cmd' nor
'rq' after do_req_filebacked() finished unless we are sure that the request
has not yet been completed. This patch fixes the following kernel crash:
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000054

Summary
In the Linux kernel, the following vulnerability has been resolved:
gve: prevent ethtool ops after shutdown
A crash can occur if an ethtool operation is invoked
after shutdown() is called.
shutdown() is invoked during system shutdown to stop DMA operations
without performing expensive deallocations. It is discouraged to
unregister the netdev in this path, so the device may still be visible
to userspace and kernel helpers.
In gve, shutdown() tears down most internal data structures. If an
ethtool operation is dispatched after shutdown(), it will dereference
freed or NULL pointers, leading to a kernel panic. While graceful
shutdown normally quiesces userspace before invoking the reboot
syscall, forced shutdowns (as observed on GCP VMs) can still trigger
this path.
Fix by calling netif_device_detach() in shutdown().
This marks the device as detached so the ethtool ioctl handler
will skip dispatching operations to the driver.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mtd: maps: Fix refcount leak in ap_flash_init
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scpi: Ensure scpi_info is not assigned if the probe fails
When scpi probe fails, at any point, we need to ensure that the scpi_info
is not set and will remain NULL until the probe succeeds. If it is not
taken care, then it could result use-after-free as the value is exported
via get_scpi_ops() and could refer to a memory allocated via devm_kzalloc()
but freed when the probe fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfs: Fix missing xas_retry() calls in xarray iteration
netfslib has a number of places in which it performs iteration of an xarray
whilst being under the RCU read lock. It *should* call xas_retry() as the
first thing inside of the loop and do "continue" if it returns true in case
the xarray walker passed out a special value indicating that the walk needs
to be redone from the root[*].
Fix this by adding the missing retry checks.
[*] I wonder if this should be done inside xas_find(), xas_next_node() and
suchlike, but I'm told that's not an simple change to effect.
This can cause an oops like that below. Note the faulting address - this
is an internal value (|0x2) returned from xarray.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: cdns3: Put the cdns set active part outside the spin lock
The device may be scheduled during the resume process,
so this cannot appear in atomic operations. Since
pm_runtime_set_active will resume suppliers, put set
active outside the spin lock, which is only used to
protect the struct cdns data structure, otherwise the
kernel will report the following warning:
BUG: sleeping function called from invalid context at drivers/base/power/runtime.c:1163
in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 651, name: sh

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: Fix a NULL pointer dereference in ath12k_mac_op_hw_scan()
In ath12k_mac_op_hw_scan(), the return value of kzalloc() is directly
used in memcpy(), which may lead to a NULL pointer dereference on
failure of kzalloc().
Fix this bug by adding a check of arg.extraie.ptr.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4

Summary
In the Linux kernel, the following vulnerability has been resolved:
vp_vdpa: fix the crash in hot unplug with vp_vdpa
While unplugging the vp_vdpa device, it triggers a kernel panic
The root cause is: vdpa_mgmtdev_unregister() will accesses modern
devices which will cause a use after free.
So need to change the sequence in vp_vdpa_remove

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda: fix potential memleak in 'add_widget_node'
As 'kobject_add' may allocated memory for 'kobject->name' when return error.
And in this function, if call 'kobject_add' failed didn't free kobject.
So call 'kobject_put' to recycling resources.

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-mq: Fix kmemleak in blk_mq_init_allocated_queue
There is a kmemleak caused by modprobe null_blk.ko
unreferenced object 0xffff8881acb1f000 (size 1024):
comm "modprobe", pid 836, jiffies 4294971190 (age 27.068s)

That is because q->ma_ops is set to NULL before blk_release_queue is
called.
blk_mq_init_queue_data
blk_mq_init_allocated_queue
blk_mq_realloc_hw_ctxs
for (i = 0; i < set->nr_hw_queues; i++) {
old_hctx = xa_load(&q->hctx_table, i);
if (!blk_mq_alloc_and_init_hctx(.., i, ..)) [1]
if (!old_hctx)
break;
xa_for_each_start(&q->hctx_table, j, hctx, j)
blk_mq_exit_hctx(q, set, hctx, j); [2]
if (!q->nr_hw_queues) [3]
goto err_hctxs;
err_exit:
q->mq_ops = NULL; [4]
blk_put_queue
blk_release_queue
if (queue_is_mq(q)) [5]
blk_mq_release(q);
[1]: blk_mq_alloc_and_init_hctx failed at i != 0.
[2]: The hctxs allocated by [1] are moved to q->unused_hctx_list and
will be cleaned up in blk_mq_release.
[3]: q->nr_hw_queues is 0.
[4]: Set q->mq_ops to NULL.
[5]: queue_is_mq returns false due to [4]. And blk_mq_release
will not be called. The hctxs in q->unused_hctx_list are leaked.
To fix it, call blk_release_queue in exception path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Handle kvm_arm_init failure correctly in finalize_pkvm
Currently there is no synchronisation between finalize_pkvm() and
kvm_arm_init() initcalls. The finalize_pkvm() proceeds happily even if
kvm_arm_init() fails resulting in the following warning on all the CPUs
and eventually a HYP panic:
| kvm [1]: IPA Size Limit: 48 bits
| kvm [1]: Failed to init hyp memory protection
| kvm [1]: error initializing Hyp mode: -22

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: b2c2: Fix use-after-free causing by irq_check_work in flexcop_pci_remove
The original code uses cancel_delayed_work() in flexcop_pci_remove(), which
does not guarantee that the delayed work item irq_check_work has fully
completed if it was already running. This leads to use-after-free scenarios
where flexcop_pci_remove() may free the flexcop_device while irq_check_work
is still active and attempts to dereference the device.
A typical race condition is illustrated below:
CPU 0 (remove) | CPU 1 (delayed work callback)
flexcop_pci_remove() | flexcop_pci_irq_check_work()
cancel_delayed_work() |
flexcop_device_kfree(fc_pci->fc_dev) |
| fc = fc_pci->fc_dev; // UAF
This is confirmed by a KASAN report:

Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensure
that the delayed work item is properly canceled and any executing delayed
work has finished before the device memory is deallocated.
This bug was initially identified through static analysis. To reproduce
and test it, I simulated the B2C2 FlexCop PCI device in QEMU and introduced
artificial delays within the flexcop_pci_irq_check_work() function to
increase the likelihood of triggering the bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mptcp: fix disconnect vs accept race
Despite commit 0ad529d9fd2b ("mptcp: fix possible divide by zero in
recvmsg()"), the mptcp protocol is still prone to a race between
disconnect() (or shutdown) and accept.
The root cause is that the mentioned commit checks the msk-level
flag, but mptcp_stream_accept() does acquire the msk-level lock,
as it can rely directly on the first subflow lock.
As reported by Christoph than can lead to a race where an msk
socket is accepted after that mptcp_subflow_queue_clean() releases
the listener socket lock and just before it takes destructive
actions leading to the following splat:

Address the issue by temporary removing the pending request socket
from the accept queue, so that racing accept() can't touch them.
After depleting the msk - the ssk still exists, as plain TCP sockets,
re-insert them into the accept queue, so that later inet_csk_listen_stop()
will complete the tcp socket disposal.

Summary
In the Linux kernel, the following vulnerability has been resolved:
perf: RISC-V: Remove PERF_HES_STOPPED flag checking in riscv_pmu_start()
Since commit 096b52fd2bb4 ("perf: RISC-V: throttle perf events") the
perf_sample_event_took() function was added to report time spent in
overflow interrupts. If the interrupt takes too long, the perf framework
will lower the sysctl_perf_event_sample_rate and max_samples_per_tick.
When hwc->interrupts is larger than max_samples_per_tick, the
hwc->interrupts will be set to MAX_INTERRUPTS, and events will be
throttled within the __perf_event_account_interrupt() function.
However, the RISC-V PMU driver doesn't call riscv_pmu_stop() to update the
PERF_HES_STOPPED flag after perf_event_overflow() in pmu_sbi_ovf_handler()
function to avoid throttling. When the perf framework unthrottled the event
in the timer interrupt handler, it triggers riscv_pmu_start() function
and causes a WARN_ON_ONCE() warning, as shown below:

After referring other PMU drivers like Arm, Loongarch, Csky, and Mips,
they don't call *_pmu_stop() to update with PERF_HES_STOPPED flag
after perf_event_overflow() function nor do they add PERF_HES_STOPPED
flag checking in *_pmu_start() which don't cause this warning.
Thus, it's recommended to remove this unnecessary check in
riscv_pmu_start() function to prevent this warning.

Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio-gpu: fix a missing check to avoid NULL dereference
'cache_ent' could be set NULL inside virtio_gpu_cmd_get_capset()
and it will lead to a NULL dereference by a lately use of it
(i.e., ptr = cache_ent->caps_cache). Fix it with a NULL check.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm: Fix potential null-ptr-deref in drm_vblank_destroy_worker()
drm_vblank_init() call drmm_add_action_or_reset() with
drm_vblank_init_release() as action. If __drmm_add_action() failed, will
directly call drm_vblank_init_release() with the vblank whose worker is
NULL. As the resule, a null-ptr-deref will happen in
kthread_destroy_worker(). Add the NULL check before calling
drm_vblank_destroy_worker().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: APEI: send SIGBUS to current task if synchronous memory error not recovered
If a synchronous error is detected as a result of user-space process
triggering a 2-bit uncorrected error, the CPU will take a synchronous
error exception such as Synchronous External Abort (SEA) on Arm64. The
kernel will queue a memory_failure() work which poisons the related
page, unmaps the page, and then sends a SIGBUS to the process, so that
a system wide panic can be avoided.
However, no memory_failure() work will be queued when abnormal
synchronous errors occur. These errors can include situations like
invalid PA, unexpected severity, no memory failure config support,
invalid GUID section, etc. In such a case, the user-space process will
trigger SEA again. This loop can potentially exceed the platform
firmware threshold or even trigger a kernel hard lockup, leading to a
system reboot.
Fix it by performing a force kill if no memory_failure() work is queued
for synchronous errors.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: fix shift-out-of-bounds in CalculateVMAndRowBytes
[WHY]
When PTEBufferSizeInRequests is zero, UBSAN reports the following
warning because dml_log2 returns an unexpected negative value:
shift exponent 4294966273 is too large for 32-bit type 'int'
[HOW]
In the case PTEBufferSizeInRequests is zero, skip the dml_log2() and
assign the result directly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/pci: Fix get_phb_number() locking
The recent change to get_phb_number() causes a DEBUG_ATOMIC_SLEEP
warning on some systems:
BUG: sleeping function called from invalid context at kernel/locking/mutex.c:580
in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 1, name: swapper
preempt_count: 1, expected: 0
RCU nest depth: 0, expected: 0
1 lock held by swapper/1:
#0: c157efb0 (hose_spinlock){+.+.}-{2:2}, at: pcibios_alloc_controller+0x64/0x220
Preemption disabled at:
[<00000000>] 0x0

[d101df30] [c001b334] ret_from_kernel_thread+0x5c/0x64
This is because pcibios_alloc_controller() holds hose_spinlock but
of_alias_get_id() takes of_mutex which can sleep.
The hose_spinlock protects the phb_bitmap, and also the hose_list, but
it doesn't need to be held while get_phb_number() calls the OF routines,
because those are only looking up information in the device tree.
So fix it by having get_phb_number() take the hose_spinlock itself, only
where required, and then dropping the lock before returning.
pcibios_alloc_controller() then needs to take the lock again before the
list_add() but that's safe, the order of the list is not important.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: hfsc: Address reentrant enqueue adding class to eltree twice
Savino says:
"We are writing to report that this recent patch
(141d34391abbb315d68556b7c67ad97885407547) [1]
can be bypassed, and a UAF can still occur when HFSC is utilized with
NETEM.
The patch only checks the cl->cl_nactive field to determine whether
it is the first insertion or not [2], but this field is only
incremented by init_vf [3].
By using HFSC_RSC (which uses init_ed) [4], it is possible to bypass the
check and insert the class twice in the eltree.
Under normal conditions, this would lead to an infinite loop in
hfsc_dequeue for the reasons we already explained in this report [5].
However, if TBF is added as root qdisc and it is configured with a
very low rate,
it can be utilized to prevent packets from being dequeued.
This behavior can be exploited to perform subsequent insertions in the
HFSC eltree and cause a UAF."
To fix both the UAF and the infinite loop, with netem as an hfsc child,
check explicitly in hfsc_enqueue whether the class is already in the eltree
whenever the HFSC_RSC flag is set.

Summary
In the Linux kernel, the following vulnerability has been resolved:
video: fbdev: arkfb: Fix a divide-by-zero bug in ark_set_pixclock()
Since the user can control the arguments of the ioctl() from the user
space, under special arguments that may result in a divide-by-zero bug
in:
drivers/video/fbdev/arkfb.c:784: ark_set_pixclock(info, (hdiv * info->var.pixclock) / hmul);
with hdiv=1, pixclock=1 and hmul=2 you end up with (1*1)/2 = (int) 0.
and then in:
drivers/video/fbdev/arkfb.c:504: rv = dac_set_freq(par->dac, 0, 1000000000 / pixclock);
we'll get a division-by-zero.
The following log can reveal it:
divide error: 0000 [#1] PREEMPT SMP KASAN PTI
RIP: 0010:ark_set_pixclock drivers/video/fbdev/arkfb.c:504 [inline]
RIP: 0010:arkfb_set_par+0x10fc/0x24c0 drivers/video/fbdev/arkfb.c:784

Fix this by checking the argument of ark_set_pixclock() first.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: nfc: nci: Add parameter validation for packet data
Syzbot reported an uninitialized value bug in nci_init_req, which was
introduced by commit 5aca7966d2a7 ("Merge tag
'perf-tools-fixes-for-v6.17-2025-09-16' of
git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools").
This bug arises due to very limited and poor input validation
that was done at nic_valid_size(). This validation only
validates the skb->len (directly reflects size provided at the
userspace interface) with the length provided in the buffer
itself (interpreted as NCI_HEADER). This leads to the processing
of memory content at the address assuming the correct layout
per what opcode requires there. This leads to the accesses to
buffer of `skb_buff->data` which is not assigned anything yet.
Following the same silent drop of packets of invalid sizes at
`nic_valid_size()`, add validation of the data in the respective
handlers and return error values in case of failure. Release
the skb if error values are returned from handlers in
`nci_nft_packet` and effectively do a silent drop
Possible TODO: because we silently drop the packets, the
call to `nci_request` will be waiting for completion of request
and will face timeouts. These timeouts can get excessively logged
in the dmesg. A proper handling of them may require to export
`nci_request_cancel` (or propagate error handling from the
nft packets handlers).

Release\nthe skb if error values are returned from handlers in\n`nci_nft_packet` and effectively do a silent drop\n\nPossible TODO: because we silently drop the packets, the\ncall to `nci_request` will be waiting for completion of request\nand will face timeouts. These timeouts can get excessively logged\nin the dmesg. A proper handling of them may require to export\n`nci_request_cancel` (or propagate error handling from the\nnft packets handlers)."

Summary
In the Linux kernel, the following vulnerability has been resolved:
sched, cpuset: Fix dl_cpu_busy() panic due to empty cs->cpus_allowed
With cgroup v2, the cpuset's cpus_allowed mask can be empty indicating
that the cpuset will just use the effective CPUs of its parent. So
cpuset_can_attach() can call task_can_attach() with an empty mask.
This can lead to cpumask_any_and() returns nr_cpu_ids causing the call
to dl_bw_of() to crash due to percpu value access of an out of bound
CPU value. For example:
[80468.182258] BUG: unable to handle page fault for address: ffffffff8b6648b0

Fix that by using effective_cpus instead. For cgroup v1, effective_cpus
is the same as cpus_allowed. For v2, effective_cpus is the real cpumask
to be used by tasks within the cpuset anyway.
Also update task_can_attach()'s 2nd argument name to cs_effective_cpus to
reflect the change. In addition, a check is added to task_can_attach()
to guard against the possibility that cpumask_any_and() may return a
value >= nr_cpu_ids.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/perf: Optimize clearing the pending PMI and remove WARN_ON for PMI check in power_pmu_disable
commit 2c9ac51b850d ("powerpc/perf: Fix PMU callbacks to clear
pending PMI before resetting an overflown PMC") added a new
function "pmi_irq_pending" in hw_irq.h. This function is to check
if there is a PMI marked as pending in Paca (PACA_IRQ_PMI).This is
used in power_pmu_disable in a WARN_ON. The intention here is to
provide a warning if there is PMI pending, but no counter is found
overflown.
During some of the perf runs, below warning is hit:

This means that there is no PMC overflown among the active events
in the PMU, but there is a PMU pending in Paca. The function
"any_pmc_overflown" checks the PMCs on active events in
cpuhw->n_events. Code snippet:
<<>>
if (any_pmc_overflown(cpuhw))
clear_pmi_irq_pending();
else
WARN_ON(pmi_irq_pending());
<<>>
Here the PMC overflown is not from active event. Example: When we do
perf record, default cycles and instructions will be running on PMC6
and PMC5 respectively. It could happen that overflowed event is currently
not active and pending PMI is for the inactive event. Debug logs from
trace_printk:
<<>>
any_pmc_overflown: idx is 5: pmc value is 0xd9a
power_pmu_disable: PMC1: 0x0, PMC2: 0x0, PMC3: 0x0, PMC4: 0x0, PMC5: 0xd9a, PMC6: 0x80002011
<<>>
Here active PMC (from idx) is PMC5 , but overflown PMC is PMC6(0x80002011).
When we handle PMI interrupt for such cases, if the PMC overflown is
from inactive event, it will be ignored. Reference commit:
commit bc09c219b2e6 ("powerpc/perf: Fix finding overflowed PMC in interrupt")
Patch addresses two changes:
1) Fix 1 : Removal of warning ( WARN_ON(pmi_irq_pending()); )
We were printing warning if no PMC is found overflown among active PMU
events, but PMI pending in PACA. But this could happen in cases where
PMC overflown is not in active PMC. An inactive event could have caused
the overflow. Hence the warning is not needed. To know pending PMI is
from an inactive event, we need to loop through all PMC's which will
cause more SPR reads via mfspr and increase in context switch. Also in
existing function: perf_event_interrupt, already we ignore PMI's
overflown when it is from an inactive PMC.
2) Fix 2: optimization in clearing pending PMI.
Currently we check for any active PMC overflown before clearing PMI
pending in Paca. This is causing additional SP

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\npowerpc/perf: Optimize clearing the pending PMI and remove WARN_ON for PMI check in power_pmu_disable\n\ncommit 2c9ac51b850d (\"powerpc/perf: Fix PMU callbacks to clear\npending PMI before resetting an overflown PMC\") added a new\nfunction \"pmi_irq_pending\" in hw_irq.h. This function is to check\nif there is a PMI marked as pending in Paca (PACA_IRQ_PMI).This is\nused in power_pmu_disable in a WARN_ON. The intention here is to\nprovide a warning if there is PMI pending, but no counter is found\noverflown.\n\nDuring some of the perf runs, below warning is hit:\n\nWARNING: CPU: 36 PID: 0 at arch/powerpc/perf/core-book3s.c:1332 power_pmu_disable+0x25c/0x2c0\n Modules linked in:\n -----\n\n NIP [c000000000141c3c] power_pmu_disable+0x25c/0x2c0\n LR [c000000000141c8c] power_pmu_disable+0x2ac/0x2c0\n Call Trace:\n [c000000baffcfb90] [c000000000141c8c] power_pmu_disable+0x2ac/0x2c0 (unreliable)\n [c000000baffcfc10] [c0000000003e2f8c] perf_pmu_disable+0x4c/0x60\n [c000000baffcfc30] [c0000000003e3344] group_sched_out.part.124+0x44/0x100\n [c000000baffcfc80] [c0000000003e353c] __perf_event_disable+0x13c/0x240\n [c000000baffcfcd0] [c0000000003dd334] event_function+0xc4/0x140\n [c000000baffcfd20] [c0000000003d855c] remote_function+0x7c/0xa0\n [c000000baffcfd50] [c00000000026c394] flush_smp_call_function_queue+0xd4/0x300\n [c000000baffcfde0] [c000000000065b24] smp_ipi_demux_relaxed+0xa4/0x100\n [c000000baffcfe20] [c0000000000cb2b0] xive_muxed_ipi_action+0x20/0x40\n [c000000baffcfe40] [c000000000207c3c] __handle_irq_event_percpu+0x8c/0x250\n [c000000baffcfee0] [c000000000207e2c] handle_irq_event_percpu+0x2c/0xa0\n [c000000baffcff10] [c000000000210a04] handle_percpu_irq+0x84/0xc0\n [c000000baffcff40] [c000000000205f14] generic_handle_irq+0x54/0x80\n [c000000baffcff60] [c000000000015740] __do_irq+0x90/0x1d0\n [c000000baffcff90] [c000000000016990] __do_IRQ+0xc0/0x140\n [c0000009732f3940] [c000000bafceaca8] 0xc000000bafceaca8\n [c0000009732f39d0] [c000000000016b78] do_IRQ+0x168/0x1c0\n [c0000009732f3a00] [c0000000000090c8] hardware_interrupt_common_virt+0x218/0x220\n\nThis means that there is no PMC overflown among the active events\nin the PMU, but there is a PMU pending in Paca. The function\n\"any_pmc_overflown\" checks the PMCs on active events in\ncpuhw-\u003en_events. Code snippet:\n\n\u003c\u003c\u003e\u003e\nif (any_pmc_overflown(cpuhw))\n \tclear_pmi_irq_pending();\n else\n \tWARN_ON(pmi_irq_pending());\n\u003c\u003c\u003e\u003e\n\nHere the PMC overflown is not from active event. Example: When we do\nperf record, default cycles and instructions will be running on PMC6\nand PMC5 respectively. It could happen that overflowed event is currently\nnot active and pending PMI is for the inactive event. Debug logs from\ntrace_printk:\n\n\u003c\u003c\u003e\u003e\nany_pmc_overflown: idx is 5: pmc value is 0xd9a\npower_pmu_disable: PMC1: 0x0, PMC2: 0x0, PMC3: 0x0, PMC4: 0x0, PMC5: 0xd9a, PMC6: 0x80002011\n\u003c\u003c\u003e\u003e\n\nHere active PMC (from idx) is PMC5 , but overflown PMC is PMC6(0x80002011).\nWhen we handle PMI interrupt for such cases, if the PMC overflown is\nfrom inactive event, it will be ignored. Reference commit:\ncommit bc09c219b2e6 (\"powerpc/perf: Fix finding overflowed PMC in interrupt\")\n\nPatch addresses two changes:\n1) Fix 1 : Removal of warning ( WARN_ON(pmi_irq_pending()); )\n We were printing warning if no PMC is found overflown among active PMU\n events, but PMI pending in PACA. But this could happen in cases where\n PMC overflown is not in active PMC. An inactive event could have caused\n the overflow. Hence the warning is not needed. To know pending PMI is\n from an inactive event, we need to loop through all PMC\u0027s which will\n cause more SPR reads via mfspr and increase in context switch. Also in\n existing function: perf_event_interrupt, already we ignore PMI\u0027s\n overflown when it is from an inactive PMC.\n\n2) Fix 2: optimization in clearing pending PMI.\n Currently we check for any active PMC overflown before clearing PMI\n pending in Paca. This is causing additional SP\n---truncated---"

It's bacause in snd_soc_init(), snd_soc_util_init() is possble to fail,
but its ret is ignored, which makes soc_dummy_dev unregistered twice.
snd_soc_init()
snd_soc_util_init()
platform_device_register_simple(soc_dummy_dev)
platform_driver_register() # fail
platform_device_unregister(soc_dummy_dev)
platform_driver_register() # success
...
snd_soc_exit()
snd_soc_util_exit()
# soc_dummy_dev will be unregistered for second time
To fix it, handle error and stop snd_soc_init() when util_init() fail.
Also clean debugfs when util_init() or driver_register() fail.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cnic: Fix use-after-free bugs in cnic_delete_task
The original code uses cancel_delayed_work() in cnic_cm_stop_bnx2x_hw(),
which does not guarantee that the delayed work item 'delete_task' has
fully completed if it was already running. Additionally, the delayed work
item is cyclic, the flush_workqueue() in cnic_cm_stop_bnx2x_hw() only
blocks and waits for work items that were already queued to the
workqueue prior to its invocation. Any work items submitted after
flush_workqueue() is called are not included in the set of tasks that the
flush operation awaits. This means that after the cyclic work items have
finished executing, a delayed work item may still exist in the workqueue.
This leads to use-after-free scenarios where the cnic_dev is deallocated
by cnic_free_dev(), while delete_task remains active and attempt to
dereference cnic_dev in cnic_delete_task().
A typical race condition is illustrated below:
CPU 0 (cleanup) | CPU 1 (delayed work callback)
cnic_netdev_event() |
cnic_stop_hw() | cnic_delete_task()
cnic_cm_stop_bnx2x_hw() | ...
cancel_delayed_work() | /* the queue_delayed_work()
flush_workqueue() | executes after flush_workqueue()*/
| queue_delayed_work()
cnic_free_dev(dev)//free | cnic_delete_task() //new instance
| dev = cp->dev; //use
Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensure
that the cyclic delayed work item is properly canceled and that any
ongoing execution of the work item completes before the cnic_dev is
deallocated. Furthermore, since cancel_delayed_work_sync() uses
__flush_work(work, true) to synchronously wait for any currently
executing instance of the work item to finish, the flush_workqueue()
becomes redundant and should be removed.
This bug was identified through static analysis. To reproduce the issue
and validate the fix, I simulated the cnic PCI device in QEMU and
introduced intentional delays — such as inserting calls to ssleep()
within the cnic_delete_task() function — to increase the likelihood
of triggering the bug.

Additionally, the delayed work\nitem is cyclic, the flush_workqueue() in cnic_cm_stop_bnx2x_hw() only\nblocks and waits for work items that were already queued to the\nworkqueue prior to its invocation. Any work items submitted after\nflush_workqueue() is called are not included in the set of tasks that the\nflush operation awaits. This means that after the cyclic work items have\nfinished executing, a delayed work item may still exist in the workqueue.\nThis leads to use-after-free scenarios where the cnic_dev is deallocated\nby cnic_free_dev(), while delete_task remains active and attempt to\ndereference cnic_dev in cnic_delete_task().\n\nA typical race condition is illustrated below:\n\nCPU 0 (cleanup) | CPU 1 (delayed work callback)\ncnic_netdev_event() |\n cnic_stop_hw() | cnic_delete_task()\n cnic_cm_stop_bnx2x_hw() | ...\n cancel_delayed_work() | /* the queue_delayed_work()\n flush_workqueue() | executes after flush_workqueue()*/\n | queue_delayed_work()\n cnic_free_dev(dev)//free | cnic_delete_task() //new instance\n | dev = cp-\u003edev; //use\n\nReplace cancel_delayed_work() with cancel_delayed_work_sync() to ensure\nthat the cyclic delayed work item is properly canceled and that any\nongoing execution of the work item completes before the cnic_dev is\ndeallocated. Furthermore, since cancel_delayed_work_sync() uses\n__flush_work(work, true) to synchronously wait for any currently\nexecuting instance of the work item to finish, the flush_workqueue()\nbecomes redundant and should be removed.\n\nThis bug was identified through static analysis. To reproduce the issue\nand validate the fix, I simulated the cnic PCI device in QEMU and\nintroduced intentional delays \u2014 such as inserting calls to ssleep()\nwithin the cnic_delete_task() function \u2014 to increase the likelihood\nof triggering the bug."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: Block switchdev mode when ADQ is active and vice versa
ADQ and switchdev are not supported simultaneously. Enabling both at the
same time can result in nullptr dereference.
To prevent this, check if ADQ is active when changing devlink mode to
switchdev mode, and check if switchdev is active when enabling ADQ.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ublk: fail to recover device if queue setup is interrupted
In ublk_ctrl_end_recovery(), if wait_for_completion_interruptible() is
interrupted by signal, queues aren't setup successfully yet, so we
have to fail UBLK_CMD_END_USER_RECOVERY, otherwise kernel oops can be
triggered.

Summary
In the Linux kernel, the following vulnerability has been resolved:
accel/qaic: Fix a leak in map_user_pages()
If get_user_pages_fast() allocates some pages but not as many as we
wanted, then the current code leaks those pages. Call put_page() on
the pages before returning.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dma-buf/dma-resv: Stop leaking on krealloc() failure
Currently dma_resv_get_fences() will leak the previously
allocated array if the fence iteration got restarted and
the krealloc_array() fails.
Free the old array by hand, and make sure we still clear
the returned *fences so the caller won't end up accessing
freed memory. Some (but not all) of the callers of
dma_resv_get_fences() seem to still trawl through the
array even when dma_resv_get_fences() failed. And let's
zero out *num_fences as well for good measure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Validate UAC3 cluster segment descriptors
UAC3 class segment descriptors need to be verified whether their sizes
match with the declared lengths and whether they fit with the
allocated buffer sizes, too. Otherwise malicious firmware may lead to
the unexpected OOB accesses.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: trigger: sysfs: fix possible memory leak in iio_sysfs_trig_init()
dev_set_name() allocates memory for name, it need be freed
when device_add() fails, call put_device() to give up the
reference that hold in device_initialize(), so that it can
be freed in kobject_cleanup() when the refcount hit to 0.
Fault injection test can trigger this:
unreferenced object 0xffff8e8340a7b4c0 (size 32):
comm "modprobe", pid 243, jiffies 4294678145 (age 48.845s)
hex dump (first 32 bytes):

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: Release folio lock on fscache read hit.
Under the current code, when cifs_readpage_worker is called, the call
contract is that the callee should unlock the page. This is documented
in the read_folio section of Documentation/filesystems/vfs.rst as:
> The filesystem should unlock the folio once the read has completed,
> whether it was successful or not.
Without this change, when fscache is in use and cache hit occurs during
a read, the page lock is leaked, producing the following stack on
subsequent reads (via mmap) to the page:
$ cat /proc/3890/task/12864/stack
[<0>] folio_wait_bit_common+0x124/0x350
[<0>] filemap_read_folio+0xad/0xf0
[<0>] filemap_fault+0x8b1/0xab0
[<0>] __do_fault+0x39/0x150
[<0>] do_fault+0x25c/0x3e0
[<0>] __handle_mm_fault+0x6ca/0xc70
[<0>] handle_mm_fault+0xe9/0x350
[<0>] do_user_addr_fault+0x225/0x6c0
[<0>] exc_page_fault+0x84/0x1b0
[<0>] asm_exc_page_fault+0x27/0x30
This requires a reboot to resolve; it is a deadlock.
Note however that the call to cifs_readpage_from_fscache does mark the
page clean, but does not free the folio lock. This happens in
__cifs_readpage_from_fscache on success. Releasing the lock at that
point however is not appropriate as cifs_readahead also calls
cifs_readpage_from_fscache and *does* unconditionally release the lock
after its return. This change therefore effectively makes
cifs_readpage_worker work like cifs_readahead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sctp: linearize cloned gso packets in sctp_rcv
A cloned head skb still shares these frag skbs in fraglist with the
original head skb. It's not safe to access these frag skbs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
stmmac: intel: Add a missing clk_disable_unprepare() call in intel_eth_pci_remove()
Commit 09f012e64e4b ("stmmac: intel: Fix clock handling on error and remove
paths") removed this clk_disable_unprepare()
This was partly revert by commit ac322f86b56c ("net: stmmac: Fix clock
handling on remove path") which removed this clk_disable_unprepare()
because:
"
While unloading the dwmac-intel driver, clk_disable_unprepare() is
being called twice in stmmac_dvr_remove() and
intel_eth_pci_remove(). This causes kernel panic on the second call.
"
However later on, commit 5ec55823438e8 ("net: stmmac: add clocks management
for gmac driver") has updated stmmac_dvr_remove() which do not call
clk_disable_unprepare() anymore.
So this call should now be called from intel_eth_pci_remove().

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Harden uplink netdev access against device unbind
The function mlx5_uplink_netdev_get() gets the uplink netdevice
pointer from mdev->mlx5e_res.uplink_netdev. However, the netdevice can
be removed and its pointer cleared when unbound from the mlx5_core.eth
driver. This results in a NULL pointer, causing a kernel panic.
BUG: unable to handle page fault for address: 0000000000001300

Ensure the pointer is valid before use by checking it for NULL. If it
is valid, immediately call netdev_hold() to take a reference, and
preventing the netdevice from being freed while it is in use.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix BUG: KASAN: null-ptr-deref in rxe_qp_do_cleanup
The function rxe_create_qp calls rxe_qp_from_init. If some error
occurs, the error handler of function rxe_qp_from_init will set
both scq and rcq to NULL.
Then rxe_create_qp calls rxe_put to handle qp. In the end,
rxe_qp_do_cleanup is called by rxe_put. rxe_qp_do_cleanup directly
accesses scq and rcq before checking them. This will cause
null-ptr-deref error.
The call graph is as below:
rxe_create_qp {
...
rxe_qp_from_init {
...
err1:
...
qp->rcq = NULL; <---rcq is set to NULL
qp->scq = NULL; <---scq is set to NULL
...
}
qp_init:
rxe_put{
...
rxe_qp_do_cleanup {
...

Summary
In the Linux kernel, the following vulnerability has been resolved:
ixgbe: fix too early devlink_free() in ixgbe_remove()
Since ixgbe_adapter is embedded in devlink, calling devlink_free()
prematurely in the ixgbe_remove() path can lead to UAF. Move devlink_free()
to the end.
KASAN report:

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: i2c: tc358743: Fix use-after-free bugs caused by orphan timer in probe
The state->timer is a cyclic timer that schedules work_i2c_poll and
delayed_work_enable_hotplug, while rearming itself. Using timer_delete()
fails to guarantee the timer isn't still running when destroyed, similarly
cancel_delayed_work() cannot ensure delayed_work_enable_hotplug has
terminated if already executing. During probe failure after timer
initialization, these may continue running as orphans and reference the
already-freed tc358743_state object through tc358743_irq_poll_timer.
The following is the trace captured by KASAN.

Replace timer_delete() with timer_delete_sync() and cancel_delayed_work()
with cancel_delayed_work_sync() to ensure proper termination of timer and
work items before resource cleanup.
This bug was initially identified through static analysis. For reproduction
and testing, I created a functional emulation of the tc358743 device via a
kernel module and introduced faults through the debugfs interface.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: fix double list_add at iwl_mvm_mac_wake_tx_queue
After successfull station association, if station queues are disabled for
some reason, the related lists are not emptied. So if some new element is
added to the list in iwl_mvm_mac_wake_tx_queue, it can match with the old
one and produce a BUG like this:
[ 46.535263] list_add corruption. prev->next should be next (ffff94c1c318a360), but was 0000000000000000. (prev=ffff94c1d02d3388).

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: dwc: Deallocate EPC memory on dw_pcie_ep_init() errors
If dw_pcie_ep_init() fails to perform any action after the EPC memory is
initialized and the MSI memory region is allocated, the latter parts won't
be undone thus causing a memory leak. Add a cleanup-on-error path to fix
these leaks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: wil6210: debugfs: fix info leak in wil_write_file_wmi()
The simple_write_to_buffer() function will succeed if even a single
byte is initialized. However, we need to initialize the whole buffer
to prevent information leaks. Just use memdup_user().

Summary
In the Linux kernel, the following vulnerability has been resolved:
tty: serial: samsung_tty: Fix a memory leak in s3c24xx_serial_getclk() when iterating clk
When the best clk is searched, we iterate over all possible clk.
If we find a better match, the previous one, if any, needs to be freed.
If a better match has already been found, we still need to free the new
one, otherwise it leaks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: xsk: disable txq irq before flushing hw
ice_qp_dis() intends to stop a given queue pair that is a target of xsk
pool attach/detach. One of the steps is to disable interrupts on these
queues. It currently is broken in a way that txq irq is turned off
*after* HW flush which in turn takes no effect.
ice_qp_dis():
-> ice_qvec_dis_irq()
--> disable rxq irq
--> flush hw
-> ice_vsi_stop_tx_ring()
-->disable txq irq
Below splat can be triggered by following steps:
- start xdpsock WITHOUT loading xdp prog
- run xdp_rxq_info with XDP_TX action on this interface
- start traffic
- terminate xdpsock

In fact, irqs were not disabled and napi managed to be scheduled and run
while xsk_pool pointer was still valid, but SW ring of xdp_buff pointers
was already freed.
To fix this, call ice_qvec_dis_irq() after ice_vsi_stop_tx_ring(). Also
while at it, remove redundant ice_clean_rx_ring() call - this is handled
in ice_qp_clean_rings().

When hfsplus_uni2asc is called from hfsplus_listxattr,
it actually passes in a struct hfsplus_attr_unistr*.
The size of the corresponding structure is different from that of hfsplus_unistr,
so the previous fix (94458781aee6) is insufficient.
The pointer on the unicode buffer is still going beyond the allocated memory.
This patch introduces two warpper functions hfsplus_uni2asc_xattr_str and
hfsplus_uni2asc_str to process two unicode buffers,
struct hfsplus_attr_unistr* and struct hfsplus_unistr* respectively.
When ustrlen value is bigger than the allocated memory size,
the ustrlen value is limited to an safe size.

"value": "AV:L - The attacker-controlled input is an on-disk HFS+ attributes B-tree key, and the vulnerable conversion is reached through the ordinary local `listxattr()`/`llistxattr()` syscall on a mounted volume; there is no network or remote-peer input path. Local rather than Physical because the volume can be attached locally via a loop device and the trigger is a plain local syscall.\nAC:L - The `length` field of the `hfsplus_attr_unistr` key name is written verbatim by the attacker in the crafted image and was clamped to 255 instead of 127, so the 256-byte overread fires deterministically on the first `listxattr()` call. No race, no heap grooming, and no condition outside the attacker\u0027s control.\nPR:L - Nothing on the `path_listxattrat` \u2192 `vfs_listxattr` \u2192 `hfsplus_listxattr` \u2192 `hfsplus_uni2asc` path performs any capability check \u2014 the only `capable(CAP_SYS_ADMIN)` test (`can_list()`) runs after the out-of-bounds conversion and merely filters `trusted.*` names. Any unprivileged local user who can traverse an HFS+ volume (e.g. one udisks2-automounted from attacker-supplied removable media) triggers it.\nUI:N - In the automount/kiosk scenario the volume is mounted by the system on device insertion with no victim action, and the attacker then issues the `listxattr()` himself; likewise an attacker with loop-mount access performs every step. Choosing the higher-severity option where the mount could otherwise be attributed to a victim.\nS:U - The out-of-bounds read, the leaked bytes, and any resulting fault all stay within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is not a bounded few-byte read: up to 256 bytes past the `kzalloc(536)` key allocation are consumed, NLS-converted into `strbuf`, and copied out to userspace by `copy_name()` plus the `copy_to_user()` in `listxattr()`, giving a direct kernel-heap disclosure channel rather than a mere oracle. On slub_debug/KASAN/KFENCE and hardened configurations those bytes are live redzone/stale slab content adjacent to the allocation.\nI:N - `hfsplus_uni2asc()` only dereferences and converts the input; the output writes are bounded by `*len_p` via `nls-\u003euni2char()` returning `-ENAMETOOLONG`. There is no out-of-bounds write, no type confusion, and no mechanism to modify kernel memory or hijack control flow.\nA:H - The slab out-of-bounds read is a guaranteed KASAN/KFENCE report and, with `panic_on_warn`/`panic_on_oops`, a kernel panic; where the overread crosses a KFENCE guard page it faults outright. It also leaves the xattr listing returning `-EIO`/garbage, rendering the volume\u0027s attribute handling unusable, and is repeatable at will by an unprivileged user."

Summary
In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: Fix mcam entry resource leak
The teardown sequence in FLR handler returns if no NIX LF
is attached to PF/VF because it indicates that graceful
shutdown of resources already happened. But there is a
chance of all allocated MCAM entries not being freed by
PF/VF. Hence free mcam entries even in case of detached LF.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: uvcvideo: Mark invalid entities with id UVC_INVALID_ENTITY_ID
Per UVC 1.1+ specification 3.7.2, units and terminals must have a non-zero
unique ID.
```
Each Unit and Terminal within the video function is assigned a unique
identification number, the Unit ID (UID) or Terminal ID (TID), contained in
the bUnitID or bTerminalID field of the descriptor. The value 0x00 is
reserved for undefined ID,
```
If we add a new entity with id 0 or a duplicated ID, it will be marked
as UVC_INVALID_ENTITY_ID.
In a previous attempt commit 3dd075fe8ebb ("media: uvcvideo: Require
entities to have a non-zero unique ID"), we ignored all the invalid units,
this broke a lot of non-compatible cameras. Hopefully we are more lucky
this time.
This also prevents some syzkaller reproducers from triggering warnings due
to a chain of entities referring to themselves. In one particular case, an
Output Unit is connected to an Input Unit, both with the same ID of 1. But
when looking up for the source ID of the Output Unit, that same entity is
found instead of the input entity, which leads to such warnings.
In another case, a backward chain was considered finished as the source ID
was 0. Later on, that entity was found, but its pads were not valid.
Here is a sample stack trace for one of those cases.

Later on, that entity was found, but its pads were not valid.\n\nHere is a sample stack trace for one of those cases.\n\n[ 20.650953] usb 1-1: new high-speed USB device number 2 using dummy_hcd\n[ 20.830206] usb 1-1: Using ep0 maxpacket: 8\n[ 20.833501] usb 1-1: config 0 descriptor??\n[ 21.038518] usb 1-1: string descriptor 0 read error: -71\n[ 21.038893] usb 1-1: Found UVC 0.00 device \u003cunnamed\u003e (2833:0201)\n[ 21.039299] uvcvideo 1-1:0.0: Entity type for entity Output 1 was not initialized!\n[ 21.041583] uvcvideo 1-1:0.0: Entity type for entity Input 1 was not initialized!\n[ 21.042218] ------------[ cut here ]------------\n[ 21.042536] WARNING: CPU: 0 PID: 9 at drivers/media/mc/mc-entity.c:1147 media_create_pad_link+0x2c4/0x2e0\n[ 21.043195] Modules linked in:\n[ 21.043535] CPU: 0 UID: 0 PID: 9 Comm: kworker/0:1 Not tainted 6.11.0-rc7-00030-g3480e43aeccf #444\n[ 21.044101] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.15.0-1 04/01/2014\n[ 21.044639] Workqueue: usb_hub_wq hub_event\n[ 21.045100] RIP: 0010:media_create_pad_link+0x2c4/0x2e0\n[ 21.045508] Code: fe e8 20 01 00 00 b8 f4 ff ff ff 48 83 c4 30 5b 41 5c 41 5d 41 5e 41 5f 5d c3 cc cc cc cc 0f 0b eb e9 0f 0b eb 0a 0f 0b eb 06 \u003c0f\u003e 0b eb 02 0f 0b b8 ea ff ff ff eb d4 66 2e 0f 1f 84 00 00 00 00\n[ 21.046801] RSP: 0018:ffffc9000004b318 EFLAGS: 00010246\n[ 21.047227] RAX: ffff888004e5d458 RBX: 0000000000000000 RCX: ffffffff818fccf1\n[ 21.047719] RDX: 000000000000007b RSI: 0000000000000000 RDI: ffff888004313290\n[ 21.048241] RBP: ffff888004313290 R08: 0001ffffffffffff R09: 0000000000000000\n[ 21.048701] R10: 0000000000000013 R11: 0001888004313290 R12: 0000000000000003\n[ 21.049138] R13: ffff888004313080 R14: ffff888004313080 R15: 0000000000000000\n[ 21.049648] FS: 0000000000000000(0000) GS:ffff88803ec00000(0000) knlGS:0000000000000000\n[ 21.050271] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[ 21.050688] CR2: 0000592cc27635b0 CR3: 000000000431c000 CR4: 0000000000750ef0\n[ 21.051136] PKRU: 55555554\n[ 21.051331] Call Trace:\n[ 21.051480] \u003cTASK\u003e\n[ 21.051611] ? __warn+0xc4/0x210\n[ 21.051861] ? media_create_pad_link+0x2c4/0x2e0\n[ 21.052252] ? report_bug+0x11b/0x1a0\n[ 21.052540] ? trace_hardirqs_on+0x31/0x40\n[ 21.052901] ? handle_bug+0x3d/0x70\n[ 21.053197] ? exc_invalid_op+0x1a/0x50\n[ 21.053511] ? asm_exc_invalid_op+0x1a/0x20\n[ 21.053924] ? media_create_pad_link+0x91/0x2e0\n[ 21.054364] ? media_create_pad_link+0x2c4/0x2e0\n[ 21.054834] ? media_create_pad_link+0x91/0x2e0\n[ 21.055131] ? _raw_spin_unlock+0x1e/0x40\n[ 21.055441] ? __v4l2_device_register_subdev+0x202/0x210\n[ 21.055837] uvc_mc_register_entities+0x358/0x400\n[ 21.056144] uvc_register_chains+0x1\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: gadget: Fix use-after-free Read in usb_udc_uevent()
The syzbot fuzzer found a race between uevent callbacks and gadget
driver unregistration that can cause a use-after-free bug:
---------------------------------------------------------------
BUG: KASAN: use-after-free in usb_udc_uevent+0x11f/0x130
drivers/usb/gadget/udc/core.c:1732
Read of size 8 at addr ffff888078ce2050 by task udevd/2968

dev_uevent+0x290/0x770 drivers/base/core.c:2424
---------------------------------------------------------------
The bug occurs because usb_udc_uevent() dereferences udc->driver but
does so without acquiring the udc_lock mutex, which protects this
field. If the gadget driver is unbound from the udc concurrently with
uevent processing, the driver structure may be accessed after it has
been deallocated.
To prevent the race, we make sure that the routine holds the mutex
around the racing accesses.

Summary
In the Linux kernel, the following vulnerability has been resolved:
perf trace: Really free the evsel->priv area
In 3cb4d5e00e037c70 ("perf trace: Free syscall tp fields in
evsel->priv") it only was freeing if strcmp(evsel->tp_format->system,
"syscalls") returned zero, while the corresponding initialization of
evsel->priv was being performed if it was _not_ zero, i.e. if the tp
system wasn't 'syscalls'.
Just stop looking for that and free it if evsel->priv was set, which
should be equivalent.
Also use the pre-existing evsel_trace__delete() function.
This resolves these leaks, detected with:
$ make EXTRA_CFLAGS="-fsanitize=address" BUILD_BPF_SKEL=1 CORESIGHT=1 O=/tmp/build/perf-tools-next -C tools/perf install-bin

Summary
In the Linux kernel, the following vulnerability has been resolved:
kernfs: Fix UAF in polling when open file is released
A use-after-free (UAF) vulnerability was identified in the PSI (Pressure
Stall Information) monitoring mechanism:
BUG: KASAN: slab-use-after-free in psi_trigger_poll+0x3c/0x140
Read of size 8 at addr ffff3de3d50bd308 by task systemd/1

cgroup_file_show+0x150/0x268
cgroup_pressure_write+0x1dc/0x340
cgroup_file_write+0x274/0x548
Reproduction Steps:
1. Open test/cpu.pressure and establish epoll monitoring
2. Disable monitoring: echo 0 > test/cgroup.pressure
3. Re-enable monitoring: echo 1 > test/cgroup.pressure
The race condition occurs because:
1. When cgroup.pressure is disabled (echo 0 > cgroup.pressure), it:
- Releases PSI triggers via cgroup_file_release()
- Frees of->priv through kernfs_drain_open_files()
2. While epoll still holds reference to the file and continues polling
3. Re-enabling (echo 1 > cgroup.pressure) accesses freed of->priv
epolling disable/enable cgroup.pressure
fd=open(cpu.pressure)
while(1)
...
epoll_wait
kernfs_fop_poll
kernfs_get_active = true echo 0 > cgroup.pressure
... cgroup_file_show
kernfs_show
// inactive kn
kernfs_drain_open_files
cft->release(of);
kfree(ctx);
...
kernfs_get_active = false
echo 1 > cgroup.pressure
kernfs_show
kernfs_activate_one(kn);
kernfs_fop_poll
kernfs_get_active = true
cgroup_file_poll
psi_trigger_poll
// UAF
...
end: close(fd)
To address this issue, introduce kernfs_get_active_of() for kernfs open
files to obtain active references. This function will fail if the open file
has been released. Replace kernfs_get_active() with kernfs_get_active_of()
to prevent further operations on released file descriptors.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dax: Fix dax_mapping_release() use after free
A CONFIG_DEBUG_KOBJECT_RELEASE test of removing a device-dax region
provider (like modprobe -r dax_hmem) yields:
kobject: 'mapping0' (ffff93eb460e8800): kobject_release, parent 0000000000000000 (delayed 2000)

Due to attempting ida_free() on an ida object that has already been
freed. Devices typically only hold a reference on their parent while
registered. If a child needs a parent object to complete its release it
needs to hold a reference that it drops from its release callback.
Arrange for a dax_mapping to pin its parent dev_dax instance until
dax_mapping_release().

Summary
In the Linux kernel, the following vulnerability has been resolved:
pwm: lpc32xx: Remove handling of PWM channels
Because LPC32xx PWM controllers have only a single output which is
registered as the only PWM device/channel per controller, it is known in
advance that pwm->hwpwm value is always 0. On basis of this fact
simplify the code by removing operations with pwm->hwpwm, there is no
controls which require channel number as input.
Even though I wasn't aware at the time when I forward ported that patch,
this fixes a null pointer dereference as lpc32xx->chip.pwms is NULL
before devm_pwmchip_add() is called.

There is no remote or adjacent-network path to this code.\nAC:L - Triggering the unlocked amdgpu_vm_bo_del() requires nothing more than closing the DRM fd, and the attacker controls both sides of the resulting race \u2014 one thread submits faulting GPU work or VRAM eviction pressure (driving amdgpu_vm_handle_fault/amdgpu_vm_bo_invalidate under the root PD reservation) while another loops open/close. On SR-IOV VFs the CSA path is taken with stock settings, requiring no special tuning.\nPR:L - Only an unprivileged local user with access to the DRM render node is needed \u2014 these are group-accessible on ordinary distributions and available to every app on Android; no capability check exists on the path from drm_release to amdgpu_driver_postclose_kms.\nUI:N - The attacker performs the fd close and the concurrent GPU submissions entirely within their own process; no victim action is involved.\nS:U - Corruption is confined to the guest/host kernel that owns the amdgpu VM; even on an SR-IOV virtual function the VF remains constrained by host GPU/IOMMU isolation, so no security authority is crossed.\nC:H - Unlocked removal from the vm-\u003eva interval tree and vm-\u003efreed list racing with locked traversals leaves freed amdgpu_bo_va_mapping objects reachable, and corrupted GPU page-table updates map DMA-visible memory, yielding an arbitrary-read primitive over kernel memory.\nI:H - The same rb-tree/list corruption and use-after-free on mapping structures provide a write primitive, and because the affected structures drive GPU PTE programming, an attacker can influence which physical memory the GPU is allowed to write.\nA:H - The path contains an explicit BUG_ON() plus the dma_resv_assert_held() WARN reported in the commit \u2014 the latter panics outright under panic_on_warn \u2014 and the underlying race produces oopses from torn interval-tree state on every fd close."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: snic: Fix possible memory leak if device_add() fails
If device_add() returns error, the name allocated by dev_set_name() needs
be freed. As the comment of device_add() says, put_device() should be used
to give up the reference in the error path. So fix this by calling
put_device(), then the name can be freed in kobject_cleanp().

Summary
In the Linux kernel, the following vulnerability has been resolved:
perf/x86/amd: Fix crash due to race between amd_pmu_enable_all, perf NMI and throttling
amd_pmu_enable_all() does:
if (!test_bit(idx, cpuc->active_mask))
continue;
amd_pmu_enable_event(cpuc->events[idx]);
A perf NMI of another event can come between these two steps. Perf NMI
handler internally disables and enables _all_ events, including the one
which nmi-intercepted amd_pmu_enable_all() was in process of enabling.
If that unintentionally enabled event has very low sampling period and
causes immediate successive NMI, causing the event to be throttled,
cpuc->events[idx] and cpuc->active_mask gets cleared by x86_pmu_stop().
This will result in amd_pmu_enable_event() getting called with event=NULL
when amd_pmu_enable_all() resumes after handling the NMIs. This causes a
kernel crash:
BUG: kernel NULL pointer dereference, address: 0000000000000198
#PF: supervisor read access in kernel mode
#PF: error_code(0x0000) - not-present page

amd_pmu_disable_all()/amd_pmu_enable_all() calls inside perf NMI handler
were recently added as part of BRS enablement but I'm not sure whether
we really need them. We can just disable BRS in the beginning and enable
it back while returning from NMI. This will solve the issue by not
enabling those events whose active_masks are set but are not yet enabled
in hw pmu.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix another off-by-one fsmap error on 1k block filesystems
Apparently syzbot figured out that issuing this FSMAP call:
struct fsmap_head cmd = {
.fmh_count = ...;
.fmh_keys = {
{ .fmr_device = /* ext4 dev */, .fmr_physical = 0, },
{ .fmr_device = /* ext4 dev */, .fmr_physical = 0, },
},
...
};
ret = ioctl(fd, FS_IOC_GETFSMAP, &cmd);
Produces this crash if the underlying filesystem is a 1k-block ext4
filesystem:

For GETFSMAP calls, the caller selects a physical block device by
writing its block number into fsmap_head.fmh_keys[01].fmr_device.
To query mappings for a subrange of the device, the starting byte of the
range is written to fsmap_head.fmh_keys[0].fmr_physical and the last
byte of the range goes in fsmap_head.fmh_keys[1].fmr_physical.
IOWs, to query what mappings overlap with bytes 3-14 of /dev/sda, you'd
set the inputs as follows:
fmh_keys[0] = { .fmr_device = major(8, 0), .fmr_physical = 3},
fmh_keys[1] = { .fmr_device = major(8, 0), .fmr_physical = 14},
Which would return you whatever is mapped in the 12 bytes starting at
physical offset 3.
The crash is due to insufficient range validation of keys[1] in
ext4_getfsmap_datadev. On 1k-block filesystems, block 0 is not part of
the filesystem, which means that s_first_data_block is nonzero.
ext4_get_group_no_and_offset subtracts this quantity from the blocknr
argument before cracking it into a group number and a block number
within a group. IOWs, block group 0 spans blocks 1-8192 (1-based)
instead of 0-8191 (0-based) like what happens with larger blocksizes.
The net result of this encoding is that blocknr < s_first_data_block is
not a valid input to this function. The end_fsb variable is set from
the keys that are copied from userspace, which means that in the above
example, its value is zero. That leads to an underflow here:
blocknr = blocknr - le32_to_cpu(es->s_first_data_block);
The division then operates on -1:
offset = do_div(blocknr, EXT4_BLOCKS_PER_GROUP(sb)) >>
EXT4_SB(sb)->s_cluster_bits;
Leaving an impossibly large group number (2^32-1) in blocknr.
ext4_getfsmap_check_keys checked that keys[0

Summary
In the Linux kernel, the following vulnerability has been resolved:
xfrm: fix slab-use-after-free in decode_session6
When the xfrm device is set to the qdisc of the sfb type, the cb field
of the sent skb may be modified during enqueuing. Then,
slab-use-after-free may occur when the xfrm device sends IPv6 packets.
The stack information is as follows:

The buggy address belongs to the object at ffff888111145800
which belongs to the cache skbuff_small_head of size 640
The buggy address is located 239 bytes inside of
freed 640-byte region [ffff888111145800, ffff888111145a80)
As commit f855691975bb ("xfrm6: Fix the nexthdr offset in
_decode_session6.") showed, xfrm_decode_session was originally intended
only for the receive path. IP6CB(skb)->nhoff is not set during
transmission. Therefore, set the cb field in the skb to 0 before
sending packets.

A remote peer can only trigger it opportunistically on a pre-existing xfrm+fq/sfb deployment, so the vector the attacker can actually establish is local.\nAC:L - The attacker fully controls every precondition: create the xfrm link, attach `sfb` with `rehash 1` to force the slot that leaves a non-zero hash in skb-\u003ecb[14..15], and transmit IPv6 packets at will with unlimited free retries. There is no race to win and no memory layout or victim state outside the attacker\u0027s influence.\nPR:L - Both RTM_NEWLINK and RTM_NEWQDISC gate only on `netlink_net_capable(skb, CAP_NET_ADMIN)`, which resolves to `ns_capable(net-\u003euser_ns, CAP_NET_ADMIN)` and is therefore satisfied by an unprivileged user inside `unshare -Urn`; the required sch_sfb and xfrm_interface modules autoload. No real root in the init namespace is needed.\nUI:N - Once the device is brought up, IPv6 addrconf on the ARPHRD_NONE xfrm interface sends router solicitations by itself (exactly the addrconf_rs_timer path in the KASAN trace), and the attacker can additionally send traffic on demand. No victim action is involved.\nS:U - The out-of-bounds read, the resulting bad policy decision, and any oops all occur within the host kernel\u0027s own security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - `nh[nhoff]` reads a byte at an entirely uncontrolled offset of up to 65535 past a ~640-byte slab object, confirmed by KASAN to land inside freed heap memory, and each packet re-randomizes the offset so an attacker can sweep a 64 KB window of adjacent kernel memory. The recovered byte becomes `flowi6_proto` and steers the xfrm policy/route lookup, providing an observable oracle for that out-of-bounds content.\nI:L - There is no write or corruption primitive \u2014 the stale byte only lands in an on-stack `flowi6` \u2014 but it causes `xfrm_lookup_with_ifid()` to select the wrong policy/SA, so outbound tunnel packets can be emitted under an unintended security association (the \"incorrect policy lookups\" failure f855691975bb was written to prevent). That is a real but limited modification of the security decision.\nA:H - A read up to 64 KB beyond the slab object can hit an unmapped or guarded page, faulting in softirq context for an immediate oops/panic, and on KASAN or hardened kernels it reports and panics outright. Independently, the garbage flow decode makes `xfrm_lookup` fail so `xfrmi_xmit2()` drops every IPv6 packet on the interface, taking the IPsec tunnel down."

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: mediatek: fix of_iomap memory leak
Smatch reports:
drivers/clk/mediatek/clk-mtk.c:583 mtk_clk_simple_probe() warn:
'base' from of_iomap() not released on lines: 496.
This problem was also found in linux-next. In mtk_clk_simple_probe(),
base is not released when handling errors
if clk_data is not existed, which may cause a leak.
So free_base should be added here to release base.

On the widely used profiling configuration dev.i915.perf_stream_paranoid=0 (the documented setting for unprivileged Intel GPU metrics collection) the perfmon_capable() check is bypassed entirely, leaving an ordinary unprivileged user able to reach the bug.\nUI:N - The attacker triggers the flaw entirely on their own by issuing the ioctl from their own process; no victim action, file open, or mount is involved.\nS:U - The out-of-bounds read and the resulting register-allowlist bypass occur within the kernel\u0027s own security authority on the same host; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The walk reads kernel module .rodata past the object bounds with no bound other than encountering a zero pair, and the function\u0027s boolean result is returned to userspace as an accept/reject oracle, letting an attacker probe addresses and reconstruct the contents of the out-of-bounds kernel memory.\nI:H - The OOB data is interpreted as additional whitelist ranges, so registers that were never meant to be programmable are accepted and then emitted as MI_LOAD_REGISTER_IMM in a kernel-built batch executed unfiltered by the GPU command streamer, giving attacker-controlled 32-bit writes to non-whitelisted GPU MMIO and defeating the very allowlist this code enforces.\nA:H - The unterminated walk can run into unmapped module memory and oops, and it reliably panics kernels built with KASAN (the reported crash signature) or configured with kasan.fault=panic/panic_on_warn; additionally, programming out-of-allowlist GPU registers can hang or wedge the GPU for all users."

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfc: pn533: Fix use-after-free bugs caused by pn532_cmd_timeout
When the pn532 uart device is detaching, the pn532_uart_remove()
is called. But there are no functions in pn532_uart_remove() that
could delete the cmd_timeout timer, which will cause use-after-free
bugs. The process is shown below:
(thread 1) | (thread 2)
| pn532_uart_send_frame
pn532_uart_remove | mod_timer(&pn532->cmd_timeout,...)
... | (wait a time)
kfree(pn532) //FREE | pn532_cmd_timeout
| pn532_uart_send_frame
| pn532->... //USE
This patch adds del_timer_sync() in pn532_uart_remove() in order to
prevent the use-after-free bugs. What's more, the pn53x_unregister_nfc()
is well synchronized, it sets nfc_dev->shutting_down to true and there
are no syscalls could restart the cmd_timeout timer.

"value": "AV:L - The vulnerable code is the host PF driver\u0027s virtchnl mailbox handler, reached by a VF writing a `VIRTCHNL_OP_CONFIG_IRQ_MAP` message over PCIe, not by any network protocol. This is the standard local/guest-to-host vector used for SR-IOV VF-to-PF interface bugs.\nAC:L - The attacker fully controls both preconditions from inside the VF \u2014 it sends `VIRTCHNL_OP_ENABLE_CHANNELS` with `num_tc \u003c 4` and then a crafted `CONFIG_IRQ_MAP` with high queue-map bits set; the sequence is deterministic with no race or memory-layout dependency. The `spoofchk off` requirement is inherent to every deployment where ADq is used at all, i.e. exactly the deployments where the code is reachable.\nPR:L - The attacker needs only control of a VF that has been legitimately assigned to them \u2014 root inside their own guest VM or container, which is the normal granted privilege level of an SR-IOV tenant. No privilege on the host or in the PF\u0027s security authority is required, and the PF handler applies no capability or \"trusted VF\" check to this opcode.\nUI:N - The malicious VF driver sends the virtchnl messages entirely on its own initiative. No action by the host administrator or any other tenant is needed once a VF is assigned.\nS:C - The attacker is confined to a VF/guest security authority, but the bypassed validation causes the host PF driver to program hardware queue-interrupt registers (`I40E_QINT_RQCTL`/`I40E_QINT_TQCTL`) for queues outside the VF\u0027s allocation \u2014 resources owned by the PF (host) and by other VFs (other tenants). Impact therefore lands beyond the vulnerable component\u0027s security authority, as in a guest-to-host/cross-tenant escape.\nC:H - `i40e_vc_isvalid_queue_id()` is invoked with a stale/zero VSI id and performs no ownership check, letting a VF get its queue map validated against a VSI belonging to the PF or another VF and then attach foreign queues to its own MSI-X vector, exposing another tenant\u0027s data-path activity. Cross-tenant exposure of resources the VF has no right to observe warrants High.\nI:H - When the gate wrongly passes, `i40e_config_irq_link_list()` writes MMIO interrupt-control registers at PF-relative queue indices derived from unvalidated VF input, modifying hardware state owned by the PF and by other VFs. Unauthorized modification of another security authority\u0027s device configuration is a High integrity impact.\nA:H - Misprogramming `QINT_RQCTL`/`QINT_TQCTL` for queues belonging to the PF or other VFs breaks their Rx/Tx interrupt delivery, stalling the host\u0027s and co-tenant VMs\u0027 network data paths; queue contexts can also be pointed at `I40E_QUEUE_END_OF_LIST`, wedging the link list. A single unprivileged VF can repeat this at will, denying service to the whole port."

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: hisilicon/sec - don't sleep when in softirq
When kunpeng920 encryption driver is used to deencrypt and decrypt
packets during the softirq, it is not allowed to use mutex lock. The
kernel will report the following error:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ftrace: Fix NULL pointer dereference in is_ftrace_trampoline when ftrace is dead
ftrace_startup does not remove ops from ftrace_ops_list when
ftrace_startup_enable fails:
register_ftrace_function
ftrace_startup
__register_ftrace_function
...
add_ftrace_ops(&ftrace_ops_list, ops)
...
...
ftrace_startup_enable // if ftrace failed to modify, ftrace_disabled is set to 1
...
return 0 // ops is in the ftrace_ops_list.
When ftrace_disabled = 1, unregister_ftrace_function simply returns without doing anything:
unregister_ftrace_function
ftrace_shutdown
if (unlikely(ftrace_disabled))
return -ENODEV; // return here, __unregister_ftrace_function is not executed,
// as a result, ops is still in the ftrace_ops_list
__unregister_ftrace_function
...
If ops is dynamically allocated, it will be free later, in this case,
is_ftrace_trampoline accesses NULL pointer:
is_ftrace_trampoline
ftrace_ops_trampoline
do_for_each_ftrace_op(op, ftrace_ops_list) // OOPS! op may be NULL!
Syzkaller reports as follows:

process and remove ops from ftrace_ops_list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
md: call __md_stop_writes in md_stop
From the link [1], we can see raid1d was running even after the path
raid_dtr -> md_stop -> __md_stop.
Let's stop write first in destructor to align with normal md-raid to
fix the KASAN issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
proc: fix UAF in proc_get_inode()
Fix race between rmmod and /proc/XXX's inode instantiation.
The bug is that pde->proc_ops don't belong to /proc, it belongs to a
module, therefore dereferencing it after /proc entry has been registered
is a bug unless use_pde/unuse_pde() pair has been used.
use_pde/unuse_pde can be avoided (2 atomic ops!) because pde->proc_ops
never changes so information necessary for inode instantiation can be
saved _before_ proc_register() in PDE itself and used later, avoiding
pde->proc_ops->... dereference.
rmmod lookup
sys_delete_module
proc_lookup_de
pde_get(de);
proc_get_inode(dir->i_sb, de);
mod->exit()
proc_remove
remove_proc_subtree
proc_entry_rundown(de);
free_module(mod);
if (S_ISREG(inode->i_mode))
if (de->proc_ops->proc_read_iter)
--> As module is already freed, will trigger UAF

No network protocol handling is involved.\nAC:L - The attacker fully controls their side of the race and can hold the window open continuously \u2014 `/proc/net` entries use `proc_net_dentry_ops` whose `.d_revalidate` always returns 0, so every single access re-runs `proc_lookup_de()`/`proc_get_inode()`, and fresh procfs mounts or netns via `unshare -Ur` defeat any dcache caching. On the realistic deployment targets (Android, embedded, automotive) module load/unload cycles are frequent and user-inducible via device/radio state changes, so no condition requires attacker-unattainable luck.\nPR:L - Triggering the vulnerable dereference requires only the ability to look up a path under /proc, which is mode 0555 and open to any unprivileged local user; no capability is checked anywhere on the lookup path. Unprivileged users can additionally use user namespaces to obtain fresh procfs/netns instances and to autoload modules that register `/proc/net` entries.\nUI:N - The attacker\u0027s exploitation loop is entirely self-driven \u2014 a continuous stat() loop on the target /proc entry \u2014 and requires no victim to open a file, mount a filesystem, or otherwise participate.\nS:U - The use-after-free occurs in kernel memory and its consequences are confined to the kernel\u0027s own security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - This is a use-after-free on freed module memory; once the vmalloc/execmem region is reclaimed and re-populated (e.g. by a subsequent module load), the stale read feeds attacker-influenceable data into inode setup, and UAF primitives of this class are leveraged for kernel memory disclosure.\nI:H - The UAF causes the kernel to select `i_fop` based on freed, potentially reallocated memory, yielding a stale-object/type-confusion condition on the instantiated inode; use-after-free on kernel structures is exploitable via heap grooming for control-flow-relevant corruption.\nA:H - The commit documents an unrecoverable oops \u2014 \"BUG: unable to handle page fault for address: fffffbfff80a702b \u2026 Oops: 0000 [#1] PREEMPT SMP KASAN PTI\" at `proc_get_inode+0x302` \u2014 and the attacker can retrigger it at will with a stat() loop, causing kernel crash/denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
md: don't dereference mddev after export_rdev()
Except for initial reference, mddev->kobject is referenced by
rdev->kobject, and if the last rdev is freed, there is no guarantee that
mddev is still valid. Hence mddev should not be used anymore after
export_rdev().
This problem can be triggered by following test for mdadm at very
low rate:
New file: mdadm/tests/23rdev-lifetime
devname=${dev0##*/}
devt=`cat /sys/block/$devname/dev`
pid=""
runtime=2
clean_up_test() {
pill -9 $pid
echo clear > /sys/block/md0/md/array_state
}
trap 'clean_up_test' EXIT
add_by_sysfs() {
while true; do
echo $devt > /sys/block/md0/md/new_dev
done
}
remove_by_sysfs(){
while true; do
echo remove > /sys/block/md0/md/dev-${devname}/state
done
}
echo md0 > /sys/module/md_mod/parameters/new_array || die "create md0 failed"
add_by_sysfs &
pid="$pid $!"
remove_by_sysfs &
pid="$pid $!"
sleep $runtime
exit 0
Test cmd:
./test --save-logs --logdir=/tmp/ --keep-going --dev=loop --tests=23rdev-lifetime
Test result:

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: stratix10-svc: Fix a potential resource leak in svc_create_memory_pool()
svc_create_memory_pool() is only called from stratix10_svc_drv_probe().
Most of resources in the probe are managed, but not this memremap() call.
There is also no memunmap() call in the file.
So switch to devm_memremap() to avoid a resource leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gfs2: Check sb_bsize_shift after reading superblock
Fuzzers like to scribble over sb_bsize_shift but in reality it's very
unlikely that this field would be corrupted on its own. Nevertheless it
should be checked to avoid the possibility of messy mount errors due to
bad calculations. It's always a fixed value based on the block size so
we can just check that it's the expected value.
Tested with:
mkfs.gfs2 -O -p lock_nolock /dev/vdb
for i in 0 -1 64 65 32 33; do
gfs2_edit -p sb field sb_bsize_shift $i /dev/vdb
mount /dev/vdb /mnt/test && umount /mnt/test
done
Before this patch we get a withdraw after
[ 76.413681] gfs2: fsid=loop0.0: fatal: invalid metadata block
[ 76.413681] bh = 19 (type: exp=5, found=4)
[ 76.413681] function = gfs2_meta_buffer, file = fs/gfs2/meta_io.c, line = 492
and with UBSAN configured we also get complaints like
[ 76.373395] UBSAN: shift-out-of-bounds in fs/gfs2/ops_fstype.c:295:19
[ 76.373815] shift exponent 4294967287 is too large for 64-bit type 'long unsigned int'
After the patch, these complaints don't appear, mount fails immediately
and we get an explanation in dmesg.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: output extra debug info if we failed to find an inline backref
[BUG]
Syzbot reported several warning triggered inside
lookup_inline_extent_backref().
[CAUSE]
As usual, the reproducer doesn't reliably trigger locally here, but at
least we know the WARN_ON() is triggered when an inline backref can not
be found, and it can only be triggered when @insert is true. (I.e.
inserting a new inline backref, which means the backref should already
exist)
[ENHANCEMENT]
After the WARN_ON(), dump all the parameters and the extent tree
leaf to help debug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/pseries/iommu: IOMMU incorrectly marks MMIO range in DDW
Power Hypervisor can possibily allocate MMIO window intersecting with
Dynamic DMA Window (DDW) range, which is over 32-bit addressing.
These MMIO pages needs to be marked as reserved so that IOMMU doesn't map
DMA buffers in this range.
The current code is not marking these pages correctly which is resulting
in LPAR to OOPS while booting. The stack is at below

There are 2 issues in the code
1. The index is "int" while the address is "unsigned long". This results in
negative value when setting the bitmap.
2. The DMA offset is page shifted but the MMIO range is used as-is (64-bit
address). MMIO address needs to be page shifted as well.

There is no network-facing path to iommu_init_table().\nAC:L - Via the VFIO path the attacker directly supplies page_shift and window_size, which set it_offset = win_addr \u003e\u003e page_shift and it_size \u2014 the exact terms in the overlap test that decides whether the corrupt loop executes \u2014 and can enumerate the hypervisor-supported page sizes to force the overlap. On a given machine the DDW and MMIO32 base addresses are deterministic, so the trigger is repeatable.\nPR:L - Exploitation requires only local access to a VFIO container and group fd, which is exactly what unprivileged device-passthrough processes (QEMU, userspace drivers) are granted by administrators; no root in the init namespace is needed. The boot/probe manifestation requires no attacker privileges at all.\nUI:N - The ioctl sequence is issued entirely by the attacker\u0027s own process, and the probe-path manifestation occurs autonomously during device initialization. No victim action is involved.\nS:C - The reserved-page mechanism exists specifically to stop the IOMMU from mapping DMA buffers over hypervisor-allocated MMIO ranges, so the mis-marking is a failure of the DMA/IOMMU isolation boundary itself, allowing device DMA to reach MMIO registers. On the VFIO path the corruption is driven from a guest/passthrough domain into host kernel state, crossing the VM boundary.\nC:H - The truncated index makes set_bit() perform an out-of-bounds atomic read-modify-write far outside the vmalloc\u0027d bitmap, and the poisoned it_reserved_start later drives find_next_bit() past the bitmap end in iommu_table_in_use(); combined with DMA/MMIO aliasing exposing hardware register contents, this is an unbounded out-of-bounds read.\nI:H - set_bit() at index 0xfffff80000000000 is an out-of-bounds write, attempted ~0x800000 times over an attacker-influenced range, giving an atomic bit-set primitive at wild kernel offsets. Additionally, DMA buffers mapped over the unreserved MMIO range write attacker-influenced data directly into hardware registers.\nA:H - The reported and confirmed outcome is a kernel oops (\"Kernel access of bad area, sig: 11\") in iommu_table_reserve_pages() that kills the LPAR during boot or device probe. The VFIO path lets this be triggered on demand against a running host."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: core: Fix possible memory leak if device_add() fails
If device_add() returns error, the name allocated by dev_set_name() needs
be freed. As the comment of device_add() says, put_device() should be used
to decrease the reference count in the error path. So fix this by calling
put_device(), then the name can be freed in kobject_cleanp().

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: fix warning in smc_rx_splice() when calling get_page()
smc_lo_register_dmb() allocates DMB buffers with kzalloc(), which are
later passed to get_page() in smc_rx_splice(). Since kmalloc memory is
not page-backed, this triggers WARN_ON_ONCE() in get_page() and prevents
holding a refcount on the buffer. This can lead to use-after-free if
the memory is released before splice_to_pipe() completes.
Use folio_alloc() instead, ensuring DMBs are page-backed and safe for
get_page().

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/srpt: Fix a use-after-free
Change the LIO port members inside struct srpt_port from regular members
into pointers. Allocate the LIO port data structures from inside
srpt_make_tport() and free these from inside srpt_make_tport(). Keep
struct srpt_device as long as either an RDMA port or a LIO target port is
associated with it. This patch decouples the lifetime of struct srpt_port
(controlled by the RDMA core) and struct srpt_port_id (controlled by LIO).
This patch fixes the following KASAN complaint:

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: zfcp: Fix double free of FSF request when qdio send fails
We used to use the wrong type of integer in 'zfcp_fsf_req_send()' to cache
the FSF request ID when sending a new FSF request. This is used in case the
sending fails and we need to remove the request from our internal hash
table again (so we don't keep an invalid reference and use it when we free
the request again).
In 'zfcp_fsf_req_send()' we used to cache the ID as 'int' (signed and 32
bit wide), but the rest of the zfcp code (and the firmware specification)
handles the ID as 'unsigned long'/'u64' (unsigned and 64 bit wide [s390x
ELF ABI]). For one this has the obvious problem that when the ID grows
past 32 bit (this can happen reasonably fast) it is truncated to 32 bit
when storing it in the cache variable and so doesn't match the original ID
anymore. The second less obvious problem is that even when the original ID
has not yet grown past 32 bit, as soon as the 32nd bit is set in the
original ID (0x80000000 = 2'147'483'648) we will have a mismatch when we
cast it back to 'unsigned long'. As the cached variable is of a signed
type, the compiler will choose a sign-extending instruction to load the 32
bit variable into a 64 bit register (e.g.: 'lgf %r11,188(%r15)'). So once
we pass the cached variable into 'zfcp_reqlist_find_rm()' to remove the
request again all the leading zeros will be flipped to ones to extend the
sign and won't match the original ID anymore (this has been observed in
practice).
If we can't successfully remove the request from the hash table again after
'zfcp_qdio_send()' fails (this happens regularly when zfcp cannot notify
the adapter about new work because the adapter is already gone during
e.g. a ChpID toggle) we will end up with a double free. We unconditionally
free the request in the calling function when 'zfcp_fsf_req_send()' fails,
but because the request is still in the hash table we end up with a stale
memory reference, and once the zfcp adapter is either reset during recovery
or shutdown we end up freeing the same memory twice.
The resulting stack traces vary depending on the kernel and have no direct
correlation to the place where the bug occurs. Here are three examples that
have been seen in practice:
list_del corruption. next->prev should be 00000001b9d13800, but was 00000000dead4ead. (next=00000001bd131a00)

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sched: sch_multiq: fix possible OOB write in multiq_tune()
q->bands will be assigned to qopt->bands to execute subsequent code logic
after kmalloc. So the old q->bands should not be used in kmalloc.
Otherwise, an out-of-bounds write will occur.

Summary
In the Linux kernel, the following vulnerability has been resolved:
pcmcia: Fix a NULL pointer dereference in __iodyn_find_io_region()
In __iodyn_find_io_region(), pcmcia_make_resource() is assigned to
res and used in pci_bus_alloc_resource(). There is a dereference of res
in pci_bus_alloc_resource(), which could lead to a NULL pointer
dereference on failure of pcmcia_make_resource().
Fix this bug by adding a check of res.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: Decrement TID on RX peer frag setup error handling
Currently, TID is not decremented before peer cleanup, during error
handling path of ath12k_dp_rx_peer_frag_setup(). This could lead to
out-of-bounds access in peer->rx_tid[].
Hence, add a decrement operation for TID, before peer cleanup to
ensures proper cleanup and prevents out-of-bounds access issues when
the RX peer frag setup fails.
Found during code review. Compile tested only.

"value": "AV:A - The vulnerable path is entered from `ath12k_mac_station_add()` when a WiFi peer is added, which in AP/mesh mode is driven by a station within radio range sending Authentication/peering frames. This requires adjacency on the 802.11 link, not routable network access.\nAC:L - The attacker drives both the trigger and the failure condition \u2014 repeated association/deauthentication floods create the peer-unmap race that makes `ath12k_dp_rx_peer_frag_setup()` return -ENOENT, and the same flood (17 DMA queue buffers plus a peer struct per station, up to 2048 peers) creates the memory pressure that fails `crypto_alloc_shash()`. Both sides of the race are attacker-controlled, and the attempt can be repeated indefinitely at no cost.\nPR:N - In AP and mesh mode the `NOTEXIST -\u003e NONE` sta_state transition occurs on receipt of an Authentication/peering frame, before the 4-way handshake verifies any credentials, so an unauthenticated station reaches `ath12k_dp_peer_setup()`. On open networks no credentials exist at all.\nUI:N - An attacking station associates with the ath12k AP on its own initiative; no action by any local user or administrator is needed.\nS:U - The out-of-bounds read, the `kfree()` of an OOB-derived pointer, and the REO LUT corruption all occur within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - `ath12k_dp_rx_peer_tid_delete()` reads a full 128-byte `ath12k_dp_rx_tid` at `peer-\u003erx_tid[17]`, 72 bytes of which lie past the end of the 2312-byte allocation in un-zeroed kmalloc-4096 slack, and copies it into a REO command element. The read is unbounded stale-slab content, not a few bounded bytes, and the recovered pointer/DMA-address values feed further driver operations.\nI:H - The path performs an out-of-bounds write (`rx_tid-\u003eactive = false` clobbers `peer-\u003emcast_keyidx`, the index used to select the group decryption key at `mac.c:8144`), zeroes another peer\u0027s TID-0 entry in the hardware-shared REO LUT at index `peer_id*17 + 17` (or writes 8 bytes past the LUT at `DP_MAX_PEER_ID`), and reaches `kfree()` on a pointer read from groomable slab slack \u2014 an arbitrary-free primitive leveragable for heap corruption and control-flow hijack.\nA:H - `kfree()` of a garbage pointer and `dma_unmap_single()` with a bogus address and size cause slab-corruption panics and IOMMU faults, while zeroing another station\u0027s REO queue address in a table the WiFi hardware reads breaks that peer\u0027s RX path and can wedge the firmware, all triggerable repeatedly by an unauthenticated nearby station."

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: Fix use-after-free caused by l2cap_reassemble_sdu
Fix the race condition between the following two flows that run in
parallel:
1. l2cap_reassemble_sdu -> chan->ops->recv (l2cap_sock_recv_cb) ->
__sock_queue_rcv_skb.
2. bt_sock_recvmsg -> skb_recv_datagram, skb_free_datagram.
An SKB can be queued by the first flow and immediately dequeued and
freed by the second flow, therefore the callers of l2cap_reassemble_sdu
can't use the SKB after that function returns. However, some places
continue accessing struct l2cap_ctrl that resides in the SKB's CB for a
short time after l2cap_reassemble_sdu returns, leading to a
use-after-free condition (the stack trace is below, line numbers for
kernel 5.19.8).
Fix it by keeping a local copy of struct l2cap_ctrl.

This is local access to the attacking context rather than remote or adjacent reachability.\nAC:L - The attacker fully controls both `num_tc` (via VIRTCHNL_OP_ENABLE_CHANNELS) and `action_meta` (via ADD/DEL_CLOUD_FILTER), so the off-by-one is hit deterministically on the first try; the `vsi_idx == 0` variant needs no heap grooming at all. The only precondition, spoofchk being disabled, is a standard runtime setting in SR-IOV VM deployments and is required for ADq generally.\nPR:L - The attacker needs the ability to drive the VF\u0027s admin queue \u2014 kernel/root inside the assigned guest or possession of the VFIO device \u2014 which is a low-privileged position relative to the host PF driver being attacked. No host privileges whatsoever are needed.\nUI:N - The malicious VF sends the virtchnl messages on its own initiative; no host administrator or other user action is required at any point.\nS:C - The malicious VF lives in a guest VM (or VF-assigned container) while the corrupted state, wild pointer dereference, and hardware filter programming all occur in the host PF driver\u0027s security authority. Impact extends to the hypervisor and to other VFs/guests sharing the adapter, crossing the guest/host boundary.\nC:H - The bug yields an unbounded OOB read \u2014 `pf-\u003evsi[]` indexed by up to 65535 from a leaked heap pointer\u0027s low bits, i.e. ~512 KB past a small kzalloc\u0027d array \u2014 whose value is then dereferenced. The VF can additionally program hardware cloud filters against the PF\u0027s or another VSI\u0027s seid, enabling interception of host and cross-guest traffic.\nI:H - A VF can reliably add and delete hardware traffic-steering filters on the host PF\u0027s main VSI, tampering with host networking, and the wild `vsi-\u003eback` pointer is used as `\u0026pf-\u003ehw` for admin-queue/MMIO operations, giving corruption potential beyond a pure read. Both effects modify state belonging to a higher security authority.\nA:H - Dereferencing the garbage `struct i40e_vsi *` obtained from the double OOB read (`vsi-\u003eseid`, then `vsi-\u003eback`) will in the general case oops or panic the host kernel, and the subsequent MMIO off a bogus `pf-\u003ehw` can wedge the adapter. A host panic takes down the hypervisor and every guest on it, and the VF can repeat the trigger at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix ttm_bo calltrace warning in psp_hw_fini
The call trace occurs when the amdgpu is removed after
the mode1 reset. During mode1 reset, from suspend to resume,
there is no need to reinitialize the ta firmware buffer
which caused the bo pin_count increase redundantly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: APEI: Fix integer overflow in ghes_estatus_pool_init()
Change num_ghes from int to unsigned int, preventing an overflow
and causing subsequent vmalloc() to fail.
The overflow happens in ghes_estatus_pool_init() when calculating
len during execution of the statement below as both multiplication
operands here are signed int:
len += (num_ghes * GHES_ESOURCE_PREALLOC_MAX_SIZE);
The following call trace is observed because of this bug:
[ 9.317108] swapper/0: vmalloc error: size 18446744071562596352, exceeds total pages, mode:0xcc0(GFP_KERNEL), nodemask=(null),cpuset=/,mems_allowed=0-1

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: nSVM: Check instead of asserting on nested TSC scaling support
Check for nested TSC scaling support on nested SVM VMRUN instead of
asserting that TSC scaling is exposed to L1 if L1's MSR_AMD64_TSC_RATIO
has diverged from KVM's default. Userspace can trigger the WARN at will
by writing the MSR and then updating guest CPUID to hide the feature
(modifying guest CPUID is allowed anytime before KVM_RUN). E.g. hacking
KVM's state_test selftest to do
vcpu_set_msr(vcpu, MSR_AMD64_TSC_RATIO, 0);
vcpu_clear_cpuid_feature(vcpu, X86_FEATURE_TSCRATEMSR);
after restoring state in a new VM+vCPU yields an endless supply of:

Summary
In the Linux kernel, the following vulnerability has been resolved:
md/raid10: fix null-ptr-deref of mreplace in raid10_sync_request
There are two check of 'mreplace' in raid10_sync_request(). In the first
check, 'need_replace' will be set and 'mreplace' will be used later if
no-Faulty 'mreplace' exists, In the second check, 'mreplace' will be
set to NULL if it is Faulty, but 'need_replace' will not be changed
accordingly. null-ptr-deref occurs if Faulty is set between two check.
Fix it by merging two checks into one. And replace 'need_replace' with
'mreplace' because their values are always the same.

JFS_IP(ipimap)->i_imap is not setting to NULL after free in diUnmount.
If jfs_remount() free JFS_IP(ipimap)->i_imap but then failed at diMount().
JFS_IP(ipimap)->i_imap will be freed once again.
Fix this problem by setting JFS_IP(ipimap)->i_imap to NULL after free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: fix validation of VF state in get resources
VF state I40E_VF_STATE_ACTIVE is not the only state in which
VF is actually active so it should not be used to determine
if a VF is allowed to obtain resources.
Use I40E_VF_STATE_RESOURCES_LOADED that is set only in
i40e_vc_get_vf_resources_msg() and cleared during reset.

This is local access from the attacking context into the host PF driver.\nAC:L - `VIRTCHNL_OP_GET_VF_RESOURCES` is accepted unconditionally whenever `I40E_VF_STATE_INIT` is set, so the VF can replay it deterministically at any time with no grooming; the deterministic damage (filter teardown, `driver_caps`/`RDMAENA` reset, spurious `ACTIVE`) needs no race at all, and the freed-VSI window is widened by the handler\u0027s own `GFP_KERNEL` sleep, which the attacker can hammer at will.\nPR:L - The attacker only needs the ability to drive the VF\u0027s admin queue \u2014 kernel/root inside the assigned guest or possession of the VFIO device \u2014 which is a low-privileged position with respect to the host PF driver under attack. No host-side privileges are required.\nUI:N - The malicious VF sends the virtchnl messages entirely on its own initiative. No host administrator or other user action is needed at any point.\nS:C - The attacker executes in a guest VM (or VF-assigned container) while the corrupted state, the freed-VSI accesses, and the MAC-filter/MMIO programming all occur in the host PF driver\u0027s security authority. Impact reaches the hypervisor and other VFs/guests sharing the adapter, crossing the guest/host boundary.\nC:H - The unserialized handler reads `vsi-\u003einfo.pvid`, `vsi-\u003ealloc_queue_pairs` and `vsi-\u003einfo.qs_handle[0]` from a VSI that `i40e_free_vf_res()` may have already released and echoes those values back to the guest in the `virtchnl_vf_resource` reply, turning a use-after-free read into a direct host-memory disclosure channel. The VF can also read back state belonging to the PF\u0027s main VSI when `lan_vsi_idx` has been zeroed.\nI:H - The same path performs `spin_lock_bh(\u0026vsi-\u003emac_filter_hash_lock)` and `i40e_del_mac_filter()` \u2014 lock and hash-list writes \u2014 on freed memory, a classic UAF write primitive, and can be aimed at `pf-\u003evsi[0]` (the host\u0027s main VSI) to delete the host\u0027s own L2 filters. Re-toggling `I40E_VF_STATE_RDMAENA` additionally re-opens `i40e_config_rdma_qvlist()`, which programs `I40E_VPINT_CEQCTL` from an unvalidated VF-supplied index.\nA:H - Dereferencing a released `struct i40e_vsi` and taking a spinlock inside freed memory will oops or panic the host kernel, and tearing down a live VF\u0027s MAC filters plus corrupting the PF\u0027s ACTIVE/RDMA state wedges networking for that VF and the adapter. A host panic takes down the hypervisor and every guest on it, and the VF can retrigger the condition indefinitely."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: ipc3-topology: Prevent double freeing of ipc_control_data via load_bytes
We have sanity checks for byte controls and if any of the fail the locally
allocated scontrol->ipc_control_data is freed up, but not set to NULL.
On a rollback path of the error the higher level code will also try to free
the scontrol->ipc_control_data which will eventually going to lead to
memory corruption as double freeing memory is not a good thing.

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: bcm: rpi: Prevent out-of-bounds access
The while loop in raspberrypi_discover_clocks() relies on the assumption
that the id of the last clock element is zero. Because this data comes
from the Videocore firmware and it doesn't guarantuee such a behavior
this could lead to out-of-bounds access. So fix this by providing
a sentinel element.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: ipset: add missing range check in bitmap_ip_uadt
When tb[IPSET_ATTR_IP_TO] is not present but tb[IPSET_ATTR_CIDR] exists,
the values of ip and ip_to are slightly swapped. Therefore, the range check
for ip should be done later, but this part is missing and it seems that the
vulnerability occurs.
So we should add missing range checks and remove unnecessary range checks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
accel/qaic: tighten bounds checking in decode_message()
Copy the bounds checking from encode_message() to decode_message().
This patch addresses the following concerns. Ensure that there is
enough space for at least one header so that we don't have a negative
size later.
if (msg_hdr_len < sizeof(*trans_hdr))
Ensure that we have enough space to read the next header from the
msg->data.
if (msg_len > msg_hdr_len - sizeof(*trans_hdr))
return -EINVAL;
Check that the trans_hdr->len is not below the minimum size:
if (hdr_len < sizeof(*trans_hdr))
This minimum check ensures that we don't corrupt memory in
decode_passthrough() when we do.
memcpy(out_trans->data, in_trans->data, len - sizeof(in_trans->hdr));
And finally, use size_add() to prevent an integer overflow:
if (size_add(msg_len, hdr_len) > msg_hdr_len)

"value": "AV:L - The malicious input is the MHI control-channel response emitted by the attached Qualcomm Cloud AI 100 PCIe/M.2 accelerator, so the attack originates from locally-attached hardware or firmware-compromised on-card QSM (the card executes untrusted tenant model workloads in cloud AI deployments), not from any network. This matches the kernel CNA precedent for analogous MHI host-driver bugs (CVE-2023-53598, CVE-2025-39790).\nAC:L - The device has complete, deterministic control over every byte of the response \u2014 magic number, sequence number, `hdr.len`, `hdr.count`, and each `wire_trans_hdr` \u2014 and `decode_message()` consumes it unconditionally; setting `trans_hdr-\u003etype = QAIC_TRANS_PASSTHROUGH_FROM_DEV` with `len = 0` reliably reaches the underflowed `memcpy()` every time, with no race, no timing window, and no memory-layout condition outside the attacker\u0027s influence.\nPR:N - No host account, credential, or capability is needed: `qaic_mhi_probe()` invokes `get_cntl_version()` \u2192 `decode_message()` automatically at device power-up, and `qaic_control_open()` installs `valid_crc_stub` so that first response\u0027s CRC is not even validated. A compromised device can also force re-entry by triggering an MHI SYS_ERROR/reset; on the user-driven path the `QAIC_MANAGE` ioctl carries flags `0` (no `DRM_ROOT_ONLY`, no `DRM_AUTH`), so an unprivileged holder of `/dev/accel/accelN` suffices.\nUI:N - The vulnerable decode runs from the MHI probe path and the control-response workqueue with no victim action required \u2014 no mount, no file open, no administrator step. Device enumeration and driver bring-up alone execute the parser.\nS:U - The out-of-bounds read and the unbounded `memcpy()` write both land in the host kernel\u0027s own heap, the same security authority as the vulnerable driver. No hypervisor, IOMMU, or sandbox boundary is crossed by the corruption itself.\nC:H - Without the `msg_len \u003e msg_hdr_len - sizeof(*trans_hdr)` guard, `trans_hdr` is read past the end of the 4 KB `kmalloc()`\u0027d (not zeroed) response buffer, and `decode_passthrough()` copies out-of-bounds source bytes into `user_msg-\u003edata`, which `qaic_manage_ioctl()` hands straight back via `copy_to_user()` \u2014 a direct kernel-heap disclosure primitive. The same underflowed copy also reads far beyond the source buffer.\nI:H - `memcpy(out_trans-\u003edata, in_trans-\u003edata, len - sizeof(in_trans-\u003ehdr))` with a device-supplied `len \u003c 8` produces a size of ~2^64, giving an out-of-bounds heap write whose source contents are entirely device-controlled, into a destination that in the probe path is a ~32-byte allocation. That is a fully controlled slab overflow suitable for adjacent-object corruption and control-flow hijack.\nA:H - The underflowed `memcpy()` walks off the end of the slab and past the mapped heap, guaranteeing slab corruption, an oops, and a kernel panic; the missing `hdr_len` minimum also permits a zero-advance transaction loop. The attacking device can repeat this on every probe or reset, denying service permanently."

Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: light: isl29028: Fix the warning in isl29028_remove()
The driver use the non-managed form of the register function in
isl29028_remove(). To keep the release order as mirroring the ordering
in probe, the driver should use non-managed form in probe, too.
The following log reveals it:

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/ttm: fix bulk_move corruption when adding a entry
When the resource is the first in the bulk_move range, adding it again
(thus moving it to the tail) will corrupt the list since the first
pointer is not moved. This eventually lead to null pointer deref in
ttm_lru_bulk_move_del()

Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: fix IRQ freeing in i40e_vsi_request_irq_msix error path
If request_irq() in i40e_vsi_request_irq_msix() fails in an iteration
later than the first, the error path wants to free the IRQs requested
so far. However, it uses the wrong dev_id argument for free_irq(), so
it does not free the IRQs correctly and instead triggers the warning:
Trying to free already-free IRQ 173

Use the same dev_id for free_irq() as for request_irq().
I tested this with inserting code to fail intentionally.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: Intel: hda: Fix potential buffer overflow by snprintf()
snprintf() returns the would-be-filled size when the string overflows
the given buffer size, hence using this value may result in the buffer
overflow (although it's unrealistic).
This patch replaces with a safer version, scnprintf() for papering
over such a potential issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: separate no-async decryption request handling from async
If we're not doing async, the handling is much simpler. There's no
reference counting, we just need to wait for the completion to wake us
up and return its result.
We should preferably also use a separate crypto_wait. I'm not seeing a
UAF as I did in the past, I think aec7961916f3 ("tls: fix race between
async notify and socket close") took care of it.
This will make the next fix easier.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: reject invalid reloc tree root keys with stack dump
[BUG]
Syzbot reported a crash that an ASSERT() got triggered inside
prepare_to_merge().
That ASSERT() makes sure the reloc tree is properly pointed back by its
subvolume tree.
[CAUSE]
After more debugging output, it turns out we had an invalid reloc tree:
BTRFS error (device loop1): reloc tree mismatch, root 8 has no reloc root, expect reloc root key (-8, 132, 8) gen 17
Note the above root key is (TREE_RELOC_OBJECTID, ROOT_ITEM,
QUOTA_TREE_OBJECTID), meaning it's a reloc tree for quota tree.
But reloc trees can only exist for subvolumes, as for non-subvolume
trees, we just COW the involved tree block, no need to create a reloc
tree since those tree blocks won't be shared with other trees.
Only subvolumes tree can share tree blocks with other trees (thus they
have BTRFS_ROOT_SHAREABLE flag).
Thus this new debug output proves my previous assumption that corrupted
on-disk data can trigger that ASSERT().
[FIX]
Besides the dedicated fix and the graceful exit, also let tree-checker to
check such root keys, to make sure reloc trees can only exist for subvolumes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
comedi: pcl726: Prevent invalid irq number
The reproducer passed in an irq number(0x80008000) that was too large,
which triggered the oob.
Added an interrupt number check to prevent users from passing in an irq
number that was too large.
If `it->options[1]` is 31, then `1 << it->options[1]` is still invalid
because it shifts a 1-bit into the sign bit (which is UB in C).
Possible solutions include reducing the upper bound on the
`it->options[1]` value to 30 or lower, or using `1U << it->options[1]`.
The old code would just not attempt to request the IRQ if the
`options[1]` value were invalid. And it would still configure the
device without interrupts even if the call to `request_irq` returned an
error. So it would be better to combine this test with the test below.

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: Fix possible memory leak for rq_wb on add_disk failure
kmemleak reported memory leaks in device_add_disk():
kmemleak: 3 new suspected memory leaks
unreferenced object 0xffff88800f420800 (size 512):
comm "modprobe", pid 4275, jiffies 4295639067 (age 223.512s)
hex dump (first 32 bytes):
04 00 00 00 08 00 00 00 01 00 00 00 00 00 00 00 ................
00 e1 f5 05 00 00 00 00 00 00 00 00 00 00 00 00 ................
backtrace:
[<00000000d3662699>] kmalloc_trace+0x26/0x60
[<00000000edc7aadc>] wbt_init+0x50/0x6f0

[<0000000060e6aab0>] nbd_dev_add+0x828/0xbf0 [nbd]
...
It is because the memory allocated in wbt_enable_default() is not
released in device_add_disk() error path.
Normally, these memory are freed in:
del_gendisk()
rq_qos_exit()
rqos->ops->exit(rqos);
wbt_exit()
So rq_qos_exit() is called to free the rq_wb memory for wbt_init().
However in the error path of device_add_disk(), only
blk_unregister_queue() is called and make rq_wb memory leaked.
Add rq_qos_exit() to the error path to fix it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
perf/x86/amd/uncore: Fix memory leak for events array
When a CPU comes online, the per-CPU NB and LLC uncore contexts are
freed but not the events array within the context structure. This
causes a memory leak as identified by the kmemleak detector.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: prio: fix a race in prio_tune()
Gerrard Tai reported a race condition in PRIO, whenever SFQ perturb timer
fires at the wrong time.
The race is as follows:
CPU 0 CPU 1
[1]: lock root
[2]: qdisc_tree_flush_backlog()
[3]: unlock root
|
| [5]: lock root
| [6]: rehash
| [7]: qdisc_tree_reduce_backlog()
|
[4]: qdisc_put()
This can be abused to underflow a parent's qlen.
Calling qdisc_purge_queue() instead of qdisc_tree_flush_backlog()
should fix the race, because all packets will be purged from the qdisc
before releasing the lock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix use-after-free bug of ns_writer on remount
If a nilfs2 filesystem is downgraded to read-only due to metadata
corruption on disk and is remounted read/write, or if emergency read-only
remount is performed, detaching a log writer and synchronizing the
filesystem can be done at the same time.
In these cases, use-after-free of the log writer (hereinafter
nilfs->ns_writer) can happen as shown in the scenario below:
Task1 Task2
-------------------------------- ------------------------------
nilfs_construct_segment
nilfs_segctor_sync
init_wait
init_waitqueue_entry
add_wait_queue
schedule
nilfs_remount (R/W remount case)
nilfs_attach_log_writer
nilfs_detach_log_writer
nilfs_segctor_destroy
kfree
finish_wait
_raw_spin_lock_irqsave
__raw_spin_lock_irqsave
do_raw_spin_lock
debug_spin_lock_before <-- use-after-free
While Task1 is sleeping, nilfs->ns_writer is freed by Task2. After Task1
waked up, Task1 accesses nilfs->ns_writer which is already freed. This
scenario diagram is based on the Shigeru Yoshida's post [1].
This patch fixes the issue by not detaching nilfs->ns_writer on remount so
that this UAF race doesn't happen. Along with this change, this patch
also inserts a few necessary read-only checks with superblock instance
where only the ns_writer pointer was used to check if the filesystem is
read-only.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: sg: Allow waiting for commands to complete on removed device
When a SCSI device is removed while in active use, currently sg will
immediately return -ENODEV on any attempt to wait for active commands that
were sent before the removal. This is problematic for commands that use
SG_FLAG_DIRECT_IO since the data buffer may still be in use by the kernel
when userspace frees or reuses it after getting ENODEV, leading to
corrupted userspace memory (in the case of READ-type commands) or corrupted
data being sent to the device (in the case of WRITE-type commands). This
has been seen in practice when logging out of a iscsi_tcp session, where
the iSCSI driver may still be processing commands after the device has been
marked for removal.
Change the policy to allow userspace to wait for active sg commands even
when the device is being removed. Return -ENODEV only when there are no
more responses to read.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext2/dax: Fix ext2_setsize when len is page aligned
PAGE_ALIGN(x) macro gives the next highest value which is multiple of
pagesize. But if x is already page aligned then it simply returns x.
So, if x passed is 0 in dax_zero_range() function, that means the
length gets passed as 0 to ->iomap_begin().
In ext2 it then calls ext2_get_blocks -> max_blocks as 0 and hits bug_on
here in ext2_get_blocks().
BUG_ON(maxblocks == 0);
Instead we should be calling dax_truncate_page() here which takes
care of it. i.e. it only calls dax_zero_range if the offset is not
page/block aligned.
This can be easily triggered with following on fsdax mounted pmem
device.
dd if=/dev/zero of=file count=1 bs=512
truncate -s 0 file
[79.525838] EXT2-fs (pmem0): DAX enabled. Warning: EXPERIMENTAL, use at your own risk

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: reject auth/assoc to AP with our address
If the AP uses our own address as its MLD address or BSSID, then
clearly something's wrong. Reject such connections so we don't
try and fail later.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: fq_pie: avoid stalls in fq_pie_timer()
When setting a high number of flows (limit being 65536),
fq_pie_timer() is currently using too much time as syzbot reported.
Add logic to yield the cpu every 2048 flows (less than 150 usec
on debug kernels).
It should also help by not blocking qdisc fast paths for too long.
Worst case (65536 flows) would need 31 jiffies for a complete scan.
Relevant extract from syzbot report:
rcu: INFO: rcu_preempt detected expedited stalls on CPUs/tasks: { 0-.... } 2663 jiffies s: 873 root: 0x1/.
rcu: blocking rcu_node structures (internal RCU debug):

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6/addrconf: fix a potential refcount underflow for idev
Now in addrconf_mod_rs_timer(), reference idev depends on whether
rs_timer is not pending. Then modify rs_timer timeout.
There is a time gap in [1], during which if the pending rs_timer
becomes not pending. It will miss to hold idev, but the rs_timer
is activated. Thus rs_timer callback function addrconf_rs_timer()
will be executed and put idev later without holding idev. A refcount
underflow issue for idev can be caused by this.
if (!timer_pending(&idev->rs_timer))
in6_dev_hold(idev);
<--------------[1]
mod_timer(&idev->rs_timer, jiffies + when);
To fix the issue, hold idev if mod_timer() return 0.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: mvpp2_main: fix possible OOB write in mvpp2_ethtool_get_rxnfc()
rules is allocated in ethtool_get_rxnfc and the size is determined by
rule_cnt from user space. So rule_cnt needs to be check before using
rules to avoid OOB writing or NULL pointer dereference.

No remote or adjacent-network input reaches this code path.\nAC:L - The attacker fully controls `info.rule_cnt` and can deterministically choose the undersized (or NULL) buffer; there is no race, no secret to guess, and no memory-layout dependency, and `queue_mode` defaults to the multi-queue mode that enables the path. The only precondition is a persistent, standard ntuple flow-steering configuration, after which the attack succeeds 100% of the time and can be repeated at will.\nPR:L - `ETHTOOL_GRXCLSRLALL` is explicitly listed in `__dev_ethtool()`\u0027s \"Allow some commands to be done by anyone\" whitelist, so it bypasses the `ns_capable(net-\u003euser_ns, CAP_NET_ADMIN)` check \u2014 any unprivileged local user, including one confined to a sandbox or container, can invoke it. Only a basic local account is needed, not root or CAP_NET_ADMIN.\nUI:N - The attacker performs the entire attack with a single ioctl from their own process; no victim action is required at attack time. The pre-existing ntuple rule configuration is ambient system state, not an interaction the attacker must induce.\nS:U - The out-of-bounds write corrupts kernel slab memory within the same kernel security authority, and the resulting RTNL deadlock/panic affects the same OS instance. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a heap out-of-bounds write into adjacent `kmalloc-8`/`kmalloc-16` objects reachable by any unprivileged user, and such slab corruption \u2014 including of SLUB freelist pointers and neighbouring length/index fields \u2014 can be groomed via userspace heap spraying into a kernel memory disclosure primitive. Per kernel scoring guidance, memory corruption leverageable for info disclosure is scored High.\nI:H - `rules[loc++] = i` writes up to 16 bytes into an attacker-sized 4/8/12-byte allocation, a genuine out-of-bounds slab write that lets the attacker overwrite fields of adjacent heap objects. Out-of-bounds writes are scored High as they are the classic basis for control-flow hijacking and privilege escalation.\nA:H - With `rule_cnt = 0` the driver writes through a NULL `rule_buf`, causing an immediate kernel oops, and the OOB variant corrupts slab freelists leading to later crashes. Because `dev_ethtool()` holds `rtnl_lock()` across the call, the oops leaves RTNL permanently held \u2014 wedging all networking configuration system-wide with unkillable D-state tasks, or panicking outright on the `panic_on_oops` appliance/embedded systems typical of mvpp2 hardware."

Summary
In the Linux kernel, the following vulnerability has been resolved:
riscv: move memblock_allow_resize() after linear mapping is ready
The initial memblock metadata is accessed from kernel image mapping. The
regions arrays need to "reallocated" from memblock and accessed through
linear mapping to cover more memblock regions. So the resizing should
not be allowed until linear mapping is ready. Note that there are
memblock allocations when building linear mapping.
This patch is similar to 24cc61d8cb5a ("arm64: memblock: don't permit
memblock resizing until linear mapping is up").
In following log, many memblock regions are reserved before
create_linear_mapping_page_table(). And then it triggered reallocation
of memblock.reserved.regions and memcpy the old array in kernel image
mapping to the new array in linear mapping which caused a page fault.

The\nregions arrays need to \"reallocated\" from memblock and accessed through\nlinear mapping to cover more memblock regions. So the resizing should\nnot be allowed until linear mapping is ready. Note that there are\nmemblock allocations when building linear mapping.\n\nThis patch is similar to 24cc61d8cb5a (\"arm64: memblock: don\u0027t permit\nmemblock resizing until linear mapping is up\").\n\nIn following log, many memblock regions are reserved before\ncreate_linear_mapping_page_table().

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-cgroup: Reinit blkg_iostat_set after clearing in blkcg_reset_stats()
When blkg_alloc() is called to allocate a blkcg_gq structure
with the associated blkg_iostat_set's, there are 2 fields within
blkg_iostat_set that requires proper initialization - blkg & sync.
The former field was introduced by commit 3b8cc6298724 ("blk-cgroup:
Optimize blkcg_rstat_flush()") while the later one was introduced by
commit f73316482977 ("blk-cgroup: reimplement basic IO stats using
cgroup rstat").
Unfortunately those fields in the blkg_iostat_set's are not properly
re-initialized when they are cleared in v1's blkcg_reset_stats(). This
can lead to a kernel panic due to NULL pointer access of the blkg
pointer. The missing initialization of sync is less problematic and
can be a problem in a debug kernel due to missing lockdep initialization.
Fix these problems by re-initializing them after memory clearing.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: make sure to abort the stream if headers are bogus
Normally we wait for the socket to buffer up the whole record
before we service it. If the socket has a tiny buffer, however,
we read out the data sooner, to prevent connection stalls.
Make sure that we abort the connection when we find out late
that the record is actually invalid. Retrying the parsing is
fine in itself but since we copy some more data each time
before we parse we can overflow the allocated skb space.
Constructing a scenario in which we're under pressure without
enough data in the socket to parse the length upfront is quite
hard. syzbot figured out a way to do this by serving us the header
in small OOB sends, and then filling in the recvbuf with a large
normal send.
Make sure that tls_rx_msg_size() aborts strp, if we reach
an invalid record there's really no way to recover.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: core: Check for rtd == NULL in snd_soc_remove_pcm_runtime()
snd_soc_remove_pcm_runtime() might be called with rtd == NULL which will
leads to null pointer dereference.
This was reproduced with topology loading and marking a link as ignore
due to missing hardware component on the system.
On module removal the soc_tplg_remove_link() would call
snd_soc_remove_pcm_runtime() with rtd == NULL since the link was ignored,
no runtime was created.

The window can be retried indefinitely at high rate until the double-queue lands.\nPR:N - No credentials exist on the path: FC fabric login is not authentication, and session create/teardown state machine transitions are processed from remote port frames before any authorization decision. No local account on the target host is required at all.\nUI:N - Session deletion and re-login are handled autonomously by the driver\u0027s discovery state machine in response to fabric events; no administrator or user action is needed.\nS:U - The corruption is confined to kernel memory managed by the qla2xxx driver within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - Double teardown causes `qlt_plogi_ack_unref()` refcount underflow and premature free of session-related objects, yielding a use-after-free on structures whose contents an attacker can influence via heap spraying \u2014 enabling kernel memory disclosure.\nI:H - Double `list_del` on `sess-\u003elist` and the dfs rport list writes attacker-influenceable pointers into freed memory, and the refcount underflow gives a UAF write primitive; both are the classic basis for control-flow hijack.\nA:H - The reported symptom is an outright system crash from linked-list corruption, and the counter underflows (`tgt-\u003esess_count`, `vha-\u003efcport_count`) also wedge the `waitQ`/`fcport_waitQ` teardown waits, hanging the HBA."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: wcd938x: fix missing mbhc init error handling
MBHC initialisation can fail so add the missing error handling to avoid
dereferencing an error pointer when later configuring the jack:

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: atlantic: fix aq_vec index out of range error
The final update statement of the for loop exceeds the array range, the
dereference of self->aq_vec[i] is not checked and then leads to the
index out of range error.
Also fixed this kind of coding style in other for loop.

Summary
In the Linux kernel, the following vulnerability has been resolved:
hfs: fix slab-out-of-bounds in hfs_bnode_read()
This patch introduces is_bnode_offset_valid() method that checks
the requested offset value. Also, it introduces
check_and_correct_requested_length() method that checks and
correct the requested length (if it is necessary). These methods
are used in hfs_bnode_read(), hfs_bnode_write(), hfs_bnode_clear(),
hfs_bnode_copy(), and hfs_bnode_move() with the goal to prevent
the access out of allocated memory and triggering the crash.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: bfa: Double-free fix
When the bfad_im_probe() function fails during initialization, the memory
pointed to by bfad->im is freed without setting bfad->im to NULL.
Subsequently, during driver uninstallation, when the state machine enters
the bfad_sm_stopping state and calls the bfad_im_probe_undo() function,
it attempts to free the memory pointed to by bfad->im again, thereby
triggering a double-free vulnerability.
Set bfad->im to NULL if probing fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: fix small mempool leak in SMB2_negotiate()
In some cases of failure (dialect mismatches) in SMB2_negotiate(), after
the request is sent, the checks would return -EIO when they should be
rather setting rc = -EIO and jumping to neg_exit to free the response
buffer from mempool.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: conntrack: Avoid nf_ct_helper_hash uses after free
If nf_conntrack_init_start() fails (for example due to a
register_nf_conntrack_bpf() failure), the nf_conntrack_helper_fini()
clean-up path frees the nf_ct_helper_hash map.
When built with NF_CONNTRACK=y, further netfilter modules (e.g:
netfilter_conntrack_ftp) can still be loaded and call
nf_conntrack_helpers_register(), independently of whether nf_conntrack
initialized correctly. This accesses the nf_ct_helper_hash dangling
pointer and causes a uaf, possibly leading to random memory corruption.
This patch guards nf_conntrack_helper_register() from accessing a freed
or uninitialized nf_ct_helper_hash pointer and fixes possible
uses-after-free when loading a conntrack module.

Summary
In the Linux kernel, the following vulnerability has been resolved:
jfs: jfs_dmap: Validate db_l2nbperpage while mounting
In jfs_dmap.c at line 381, BLKTODMAP is used to get a logical block
number inside dbFree(). db_l2nbperpage, which is the log2 number of
blocks per page, is passed as an argument to BLKTODMAP which uses it
for shifting.
Syzbot reported a shift out-of-bounds crash because db_l2nbperpage is
too big. This happens because the large value is set without any
validation in dbMount() at line 181.
Thus, make sure that db_l2nbperpage is correct while mounting.
Max number of blocks per page = Page size / Min block size
=> log2(Max num_block per page) = log2(Page size / Min block size)
= log2(Page size) - log2(Min block size)
=> Max db_l2nbperpage = L2PSIZE - L2MINBLOCKSIZE

Summary
In the Linux kernel, the following vulnerability has been resolved:
hv_netvsc: Fix panic during namespace deletion with VF
The existing code move the VF NIC to new namespace when NETDEV_REGISTER is
received on netvsc NIC. During deletion of the namespace,
default_device_exit_batch() >> default_device_exit_net() is called. When
netvsc NIC is moved back and registered to the default namespace, it
automatically brings VF NIC back to the default namespace. This will cause
the default_device_exit_net() >> for_each_netdev_safe loop unable to detect
the list end, and hit NULL ptr:

Summary
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: Fix null-ptr-deref when xps sysfs alloc failed
There is a null-ptr-deref when xps sysfs alloc failed:
BUG: KASAN: null-ptr-deref in sysfs_do_create_link_sd+0x40/0xd0
Read of size 8 at addr 0000000000000030 by task gssproxy/457

When the xprt_switch sysfs alloc failed, should not add xprt and
switch sysfs to it, otherwise, maybe null-ptr-deref; also initialize
the 'xps_sysfs' to NULL to avoid oops when destroy it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: ipset: fix region locking in hash types
Region locking introduced in v5.6-rc4 contained three macros to handle
the region locks: ahash_bucket_start(), ahash_bucket_end() which gave
back the start and end hash bucket values belonging to a given region
lock and ahash_region() which should give back the region lock belonging
to a given hash bucket. The latter was incorrect which can lead to a
race condition between the garbage collector and adding new elements
when a hash type of set is defined with timeouts.

Remote packets can drive `mtype_add()` via the `xt_set` SET target, but only when the administrator has configured such a rule, so the base score uses the self-contained local path.\nAC:L - The attacker provisions both sides of the race: they choose `hashsize \u003e= 2048` (which is what breaks the modulo-vs-division region mapping) and a short `timeout` that pins the GC period to the `HZ/10` floor, then churn add/del indefinitely with roughly half of all operations taking the wrong region lock. No condition depends on attacker-uncontrollable state, and failed attempts are freely retriable.\nPR:L - Access is gated on `netlink_net_capable(skb, CAP_NET_ADMIN)` and `ns_capable(net-\u003euser_ns, CAP_NET_ADMIN)`, both evaluated against the network namespace\u0027s user namespace, so an unprivileged user obtains it with `unshare -Urn`; ipset state is fully per-netns, so the whole attack works inside the sandbox.\nUI:N - The attacker creates the set, generates the element churn, and the garbage collector fires automatically from a delayed work item. No victim action is involved at any point.\nS:U - The corruption is confined to the kernel heap and is exploited for privilege escalation within the same kernel security authority; no VM, IOMMU, or hypervisor boundary is crossed.\nC:H - The unserialized GC/add race yields use-after-free of hbucket objects and of extension data freed by `ip_set_ext_destroy()`, and stale resurrected buckets let freed slab contents be read back to userspace via `ipset list`, giving an arbitrary-read primitive.\nI:H - GC\u0027s shrink path can copy more used entries than `tmp-\u003esize` accounts for when a concurrent `mtype_add()` bumps `n-\u003epos` under a different lock, producing a heap out-of-bounds write of attacker-controlled element bytes; the double `kfree_rcu()` on the same hbucket additionally corrupts the SLUB freelist, both of which are standard arbitrary-write/control-flow-hijack primitives.\nA:H - Enqueuing the same `rcu_head` twice corrupts the RCU callback list (cycle \u2192 hang in `rcu_do_batch`), and the double free plus out-of-bounds writes reliably produce slab corruption, oops, and panic."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: fix race condition to UAF in snd_usbmidi_free
The previous commit 0718a78f6a9f ("ALSA: usb-audio: Kill timer properly at
removal") patched a UAF issue caused by the error timer.
However, because the error timer kill added in this patch occurs after the
endpoint delete, a race condition to UAF still occurs, albeit rarely.
Additionally, since kill-cleanup for urb is also missing, freed memory can
be accessed in interrupt context related to urb, which can cause UAF.
Therefore, to prevent this, error timer and urb must be killed before
freeing the heap memory.

Summary
In the Linux kernel, the following vulnerability has been resolved:
soundwire: qcom: fix storing port config out-of-bounds
The 'qcom_swrm_ctrl->pconfig' has size of QCOM_SDW_MAX_PORTS (14),
however we index it starting from 1, not 0, to match real port numbers.
This can lead to writing port config past 'pconfig' bounds and
overwriting next member of 'qcom_swrm_ctrl' struct. Reported also by
smatch:
drivers/soundwire/qcom.c:1269 qcom_swrm_get_port_config() error: buffer overflow 'ctrl->pconfig' 14 <= 14

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: Intel: hda-ipc: Do not process IPC reply before firmware boot
It is not yet clear, but it is possible to create a firmware so broken
that it will send a reply message before a FW_READY message (it is not
yet clear if FW_READY will arrive later).
Since the reply_data is allocated only after the FW_READY message, this
will lead to a NULL pointer dereference if not filtered out.
The issue was reported with IPC4 firmware but the same condition is present
for IPC3.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xfrm: xfrm_alloc_spi shouldn't use 0 as SPI
x->id.spi == 0 means "no SPI assigned", but since commit
94f39804d891 ("xfrm: Duplicate SPI Handling"), we now create states
and add them to the byspi list with this value.
__xfrm_state_delete doesn't remove those states from the byspi list,
since they shouldn't be there, and this shows up as a UAF the next
time we go through the byspi list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
phy: hisilicon: Fix an out of bounds check in hisi_inno_phy_probe()
The size of array 'priv->ports[]' is INNO_PHY_PORT_NUM.
In the for loop, 'i' is used as the index for array 'priv->ports[]'
with a check (i > INNO_PHY_PORT_NUM) which indicates that
INNO_PHY_PORT_NUM is allowed value for 'i' in the same loop.
This > comparison needs to be changed to >=, otherwise it potentially leads
to an out of bounds write on the next iteration through the loop

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: core: config: Prevent OOB read in SS endpoint companion parsing
usb_parse_ss_endpoint_companion() checks descriptor type before length,
enabling a potentially odd read outside of the buffer size.
Fix this up by checking the size first before looking at any of the
fields in the descriptor.

Summary
In the Linux kernel, the following vulnerability has been resolved:
coresight: trbe: Return NULL pointer for allocation failures
When the TRBE driver fails to allocate a buffer, it currently returns
the error code "-ENOMEM". However, the caller etm_setup_aux() only
checks for a NULL pointer, so it misses the error. As a result, the
driver continues and eventually causes a kernel panic.
Fix this by returning a NULL pointer from arm_trbe_alloc_buffer() on
allocation failures. This allows that the callers can properly handle
the failure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/sched: Fix potential double free in drm_sched_job_add_resv_dependencies
When adding dependencies with drm_sched_job_add_dependency(), that
function consumes the fence reference both on success and failure, so in
the latter case the dma_fence_put() on the error path (xarray failed to
expand) is a double free.
Interestingly this bug appears to have been present ever since
commit ebd5f74255b9 ("drm/sched: Add dependency tracking"), since the code
back then looked like this:
drm_sched_job_add_implicit_dependencies():
...
for (i = 0; i < fence_count; i++) {
ret = drm_sched_job_add_dependency(job, fences[i]);
if (ret)
break;
}
for (; i < fence_count; i++)
dma_fence_put(fences[i]);
Which means for the failing 'i' the dma_fence_put was already a double
free. Possibly there were no users at that time, or the test cases were
insufficient to hit it.
The bug was then only noticed and fixed after
commit 9c2ba265352a ("drm/scheduler: use new iterator in drm_sched_job_add_implicit_dependencies v2")
landed, with its fixup of
commit 4eaf02d6076c ("drm/scheduler: fix drm_sched_job_add_implicit_dependencies").
At that point it was a slightly different flavour of a double free, which
commit 963d0b356935 ("drm/scheduler: fix drm_sched_job_add_implicit_dependencies harder")
noticed and attempted to fix.
But it only moved the double free from happening inside the
drm_sched_job_add_dependency(), when releasing the reference not yet
obtained, to the caller, when releasing the reference already released by
the former in the failure case.
As such it is not easy to identify the right target for the fixes tag so
lets keep it simple and just continue the chain.
While fixing we also improve the comment and explain the reason for taking
the reference and not dropping it.

Reclaiming that memory with attacker-controlled data allows disclosure of kernel memory contents via the stale fence dereferences.\nI:H - The freed dma_fence is subsequently dereferenced through its ops table (-\u003esignaled, -\u003ewait, -\u003erelease) and its dma_fence_cb callback list, both of which are function pointers in the freed allocation. Heap grooming of the reclaimed object therefore yields a write/control-flow-hijack primitive, i.e. potential privilege escalation.\nA:H - Even without successful grooming, the refcount underflow and premature free cause use-after-free dereferences in the GPU scheduler, producing an oops/panic or GPU-wide hang.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rose: Fix NULL pointer dereference in rose_send_frame()
The syzkaller reported an issue:
KASAN: null-ptr-deref in range [0x0000000000000380-0x0000000000000387]
CPU: 0 PID: 4069 Comm: kworker/0:15 Not tainted 6.0.0-syzkaller-02734-g0326074ff465 #0

</IRQ>
It triggers NULL pointer dereference when 'neigh->dev->dev_addr' is
called in the rose_send_frame(). It's the first occurrence of the
`neigh` is in rose_loopback_timer() as `rose_loopback_neigh', and
the 'dev' in 'rose_loopback_neigh' is initialized sa nullptr.
It had been fixed by commit 3b3fd068c56e3fbea30090859216a368398e39bf
("rose: Fix Null pointer dereference in rose_send_frame()") ever.
But it's introduced by commit 3c53cd65dece47dd1f9d3a809f32e59d1d87b2b8
("rose: check NULL rose_loopback_neigh->loopback") again.
We fix it by add NULL check in rose_transmit_clear_request(). When
the 'dev' in 'neigh' is NULL, we don't reply the request and just
clear it.
syzkaller don't provide repro, and I provide a syz repro like:
r0 = syz_init_net_socket$bt_sco(0x1f, 0x5, 0x2)
ioctl$sock_inet_SIOCSIFFLAGS(r0, 0x8914, &(0x7f0000000180)={'rose0\x00', 0x201})
r1 = syz_init_net_socket$rose(0xb, 0x5, 0x0)
bind$rose(r1, &(0x7f00000000c0)=@full={0xb, @dev, @null, 0x0, [@null, @null, @netrom, @netrom, @default, @null]}, 0x40)
connect$rose(r1, &(0x7f0000000240)=@short={0xb, @dev={0xbb, 0xbb, 0xbb, 0x1, 0x0}, @remote={0xcc, 0xcc, 0xcc, 0xcc, 0xcc, 0xcc, 0x1}, 0x1, @netrom={0xbb, 0xbb, 0xbb, 0xbb, 0xbb, 0x0, 0x0}}, 0x1c)

Summary
In the Linux kernel, the following vulnerability has been resolved:
mISDN: fix possible memory leak in mISDN_register_device()
Afer commit 1fa5ae857bb1 ("driver core: get rid of struct device's
bus_id string array"), the name of device is allocated dynamically,
add put_device() to give up the reference, so that the name can be
freed in kobject_cleanup() when the refcount is 0.
Set device class before put_device() to avoid null release() function
WARN message in device_release().

Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: Fix simplification of devm_spi_register_controller
This reverts commit 59ebbe40fb51 ("spi: simplify
devm_spi_register_controller").
If devm_add_action() fails in devm_add_action_or_reset(),
devm_spi_unregister() will be called, it decreases the
refcount of 'ctlr->dev' to 0, then it will cause uaf in
the drivers that calling spi_put_controller() in error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix buffer free/clear order in deferred receive path
Fix a use-after-free window by correcting the buffer release sequence in
the deferred receive path. The code freed the RQ buffer first and only
then cleared the context pointer under the lock. Concurrent paths (e.g.,
ABTS and the repost path) also inspect and release the same pointer under
the lock, so the old order could lead to double-free/UAF.
Note that the repost path already uses the correct pattern: detach the
pointer under the lock, then free it after dropping the lock. The
deferred path should do the same.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: nSVM: Load L1's TSC multiplier based on L1 state, not L2 state
When emulating nested VM-Exit, load L1's TSC multiplier if L1's desired
ratio doesn't match the current ratio, not if the ratio L1 is using for
L2 diverges from the default. Functionally, the end result is the same
as KVM will run L2 with L1's multiplier if L2's multiplier is the default,
i.e. checking that L1's multiplier is loaded is equivalent to checking if
L2 has a non-default multiplier.
However, the assertion that TSC scaling is exposed to L1 is flawed, as
userspace can trigger the WARN at will by writing the MSR and then
updating guest CPUID to hide the feature (modifying guest CPUID is
allowed anytime before KVM_RUN). E.g. hacking KVM's state_test
selftest to do
vcpu_set_msr(vcpu, MSR_AMD64_TSC_RATIO, 0);
vcpu_clear_cpuid_feature(vcpu, X86_FEATURE_TSCRATEMSR);
after restoring state in a new VM+vCPU yields an endless supply of:
------------[ cut here ]------------

Unlike the nested VMRUN path, hoisting the svm->tsc_scaling_enabled check
into the if-statement is wrong as KVM needs to ensure L1's multiplier is
loaded in the above scenario. Alternatively, the WARN_ON() could simply
be deleted, but that would make KVM's behavior even more subtle, e.g. it's
not immediately obvious why it's safe to write MSR_AMD64_TSC_RATIO when
checking only tsc_ratio_msr.

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: etas_es58x: populate ndo_change_mtu() to prevent buffer overflow
Sending an PF_PACKET allows to bypass the CAN framework logic and to
directly reach the xmit() function of a CAN driver. The only check
which is performed by the PF_PACKET framework is to make sure that
skb->len fits the interface's MTU.
Unfortunately, because the etas_es58x driver does not populate its
net_device_ops->ndo_change_mtu(), it is possible for an attacker to
configure an invalid MTU by doing, for example:
$ ip link set can0 mtu 9999
After doing so, the attacker could open a PF_PACKET socket using the
ETH_P_CANXL protocol:
socket(PF_PACKET, SOCK_RAW, htons(ETH_P_CANXL));
to inject a malicious CAN XL frames. For example:
struct canxl_frame frame = {
.flags = 0xff,
.len = 2048,
};
The CAN drivers' xmit() function are calling can_dev_dropped_skb() to
check that the skb is valid, unfortunately under above conditions, the
malicious packet is able to go through can_dev_dropped_skb() checks:
1. the skb->protocol is set to ETH_P_CANXL which is valid (the
function does not check the actual device capabilities).
2. the length is a valid CAN XL length.
And so, es58x_start_xmit() receives a CAN XL frame which it is not
able to correctly handle and will thus misinterpret it as a CAN(FD)
frame.
This can result in a buffer overflow. For example, using the es581.4
variant, the frame will be dispatched to es581_4_tx_can_msg(), go
through the last check at the beginning of this function:
if (can_is_canfd_skb(skb))
return -EMSGSIZE;
and reach this line:
memcpy(tx_can_msg->data, cf->data, cf->len);
Here, cf->len corresponds to the flags field of the CAN XL frame. In
our previous example, we set canxl_frame->flags to 0xff. Because the
maximum expected length is 8, a buffer overflow of 247 bytes occurs!
Populate net_device_ops->ndo_change_mtu() to ensure that the
interface's MTU can not be set to anything bigger than CAN_MTU or
CANFD_MTU (depending on the device capabilities). By fixing the root
cause, this prevents the buffer overflow.

"value": "AV:L - Exploitation requires local syscalls on the host \u2014 creating a PF_PACKET/SOCK_RAW socket with ETH_P_CANXL and sendmsg() to the can interface (optionally preceded by an rtnetlink MTU change), with the frame reaching es58x_start_xmit() via dev_queue_xmit(). No remote or adjacent network peer can reach this path; the CAN bus itself is only the sink, not the source.\nAC:L - The overflow is fully deterministic: can_dropped_invalid_skb() accepts an ETH_P_CANXL skb on a non-XL device, es581_4_tx_can_msg()/es58x_fd_tx_can_msg() then reinterpret canxl_frame.flags as can_frame.len and memcpy() up to 255 attacker-chosen bytes into an 8-byte (or 64-byte) field. No race, no memory-layout guessing, and no condition outside the attacker\u0027s control is needed to trigger it.\nPR:L - The two gates are ns_capable(net-\u003euser_ns, CAP_NET_RAW) in packet_create() and ns_capable(CAP_NET_ADMIN) for the MTU change \u2014 both namespaced, and CAN netdevs are not netns-local, so a can0 delegated into a container/user namespace lets an otherwise unprivileged user hold both (CAP_NET_RAW is granted by default in typical container runtimes). No real root in the init namespace is required.\nUI:N - The attacker performs every step alone \u2014 bring the interface up, optionally set the MTU, open the packet socket and send the malicious CAN XL frame. No victim action or interaction is needed.\nS:U - The corruption stays within the kernel of the same host; there is no VM, IOMMU, or hypervisor boundary crossed. Impact and vulnerable component share one security authority.\nC:H - With a minimal skb (skb-\u003elen as low as 13\u201316 bytes, permitted even at the default CAN_MTU), memcpy() reads cf-\u003elen (up to 255) bytes from the small skb data area, over-reading adjacent kernel heap; that leaked memory is placed into the URB transfer buffer and DMA\u0027d out to the USB device, giving a readable kernel-memory disclosure primitive.\nI:H - Up to 247 bytes of attacker-controlled data are written past the intended message slot; for the ES581.4 the TX buffer is a ~509-byte usb_alloc_coherent() allocation served from the HCD\u0027s shared 512-byte dma_pool, so the overflow lands in adjacent in-use DMA buffers belonging to other USB transfers \u2014 a controlled out-of-bounds write suitable for further corruption.\nA:H - Corrupting neighbouring USB DMA-pool blocks and pool metadata reliably produces kernel oops/panic or wedged USB transfers, and the overflow can be re-triggered at will from an unprivileged socket, so the whole system\u0027s availability is at stake."

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: qcom: Fix potential memory leak
Function dwc3_qcom_probe() allocates memory for resource structure
which is pointed by parent_res pointer. This memory is not
freed. This leads to memory leak. Use stack memory to prevent
memory leak.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: Clear tcp_sk(sk)->fastopen_rsk in tcp_disconnect().
syzbot reported the splat below where a socket had tcp_sk(sk)->fastopen_rsk
in the TCP_ESTABLISHED state. [0]
syzbot reused the server-side TCP Fast Open socket as a new client before
the TFO socket completes 3WHS:
1. accept()
2. connect(AF_UNSPEC)
3. connect() to another destination
As of accept(), sk->sk_state is TCP_SYN_RECV, and tcp_disconnect() changes
it to TCP_CLOSE and makes connect() possible, which restarts timers.
Since tcp_disconnect() forgot to clear tcp_sk(sk)->fastopen_rsk, the
retransmit timer triggered the warning and the intended packet was not
retransmitted.
Let's call reqsk_fastopen_remove() in tcp_disconnect().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: addrlabel: fix infoleak when sending struct ifaddrlblmsg to network
When copying a `struct ifaddrlblmsg` to the network, __ifal_reserved
remained uninitialized, resulting in a 1-byte infoleak:

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: imx: clk-imx8mn: fix memory leak in imx8mn_clocks_probe
Use devm_of_iomap() instead of of_iomap() to automatically handle
the unused ioremap region.
If any error occurs, regions allocated by kzalloc() will leak,
but using devm_kzalloc() instead will automatically free the memory
using devm_kfree().

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915: mark requests for GuC virtual engines to avoid use-after-free
References to i915_requests may be trapped by userspace inside a
sync_file or dmabuf (dma-resv) and held indefinitely across different
proceses. To counter-act the memory leaks, we try to not to keep
references from the request past their completion.
On the other side on fence release we need to know if rq->engine
is valid and points to hw engine (true for non-virtual requests).
To make it possible extra bit has been added to rq->execution_mask,
for marking virtual engines.
(cherry picked from commit 280410677af763f3871b93e794a199cfcf6fb580)

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: Gadget: core: Help prevent panic during UVC unconfigure
Avichal Rakesh reported a kernel panic that occurred when the UVC
gadget driver was removed from a gadget's configuration. The panic
involves a somewhat complicated interaction between the kernel driver
and a userspace component (as described in the Link tag below), but
the analysis did make one thing clear: The Gadget core should
accomodate gadget drivers calling usb_gadget_deactivate() as part of
their unbind procedure.
Currently this doesn't work. gadget_unbind_driver() calls
driver->unbind() while holding the udc->connect_lock mutex, and
usb_gadget_deactivate() attempts to acquire that mutex, which will
result in a deadlock.
The simple fix is for gadget_unbind_driver() to release the mutex when
invoking the ->unbind() callback. There is no particular reason for
it to be holding the mutex at that time, and the mutex isn't held
while the ->bind() callback is invoked. So we'll drop the mutex
before performing the unbind callback and reacquire it afterward.
We'll also add a couple of comments to usb_gadget_activate() and
usb_gadget_deactivate(). Because they run in process context they
must not be called from a gadget driver's ->disconnect() callback,
which (according to the kerneldoc for struct usb_gadget_driver in
include/linux/usb/gadget.h) may run in interrupt context. This may
help prevent similar bugs from arising in the future.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_conn: fail SCO/ISO via hci_conn_failed if ACL gone early
Not calling hci_(dis)connect_cfm before deleting conn referred to by a
socket generally results to use-after-free.
When cleaning up SCO connections when the parent ACL is deleted too
early, use hci_conn_failed to do the connection cleanup properly.
We also need to clean up ISO connections in a similar situation when
connecting has started but LE Create CIS is not yet sent, so do it too
here.

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: sun4i_can: populate ndo_change_mtu() to prevent buffer overflow
Sending an PF_PACKET allows to bypass the CAN framework logic and to
directly reach the xmit() function of a CAN driver. The only check
which is performed by the PF_PACKET framework is to make sure that
skb->len fits the interface's MTU.
Unfortunately, because the sun4i_can driver does not populate its
net_device_ops->ndo_change_mtu(), it is possible for an attacker to
configure an invalid MTU by doing, for example:
$ ip link set can0 mtu 9999
After doing so, the attacker could open a PF_PACKET socket using the
ETH_P_CANXL protocol:
socket(PF_PACKET, SOCK_RAW, htons(ETH_P_CANXL))
to inject a malicious CAN XL frames. For example:
struct canxl_frame frame = {
.flags = 0xff,
.len = 2048,
};
The CAN drivers' xmit() function are calling can_dev_dropped_skb() to
check that the skb is valid, unfortunately under above conditions, the
malicious packet is able to go through can_dev_dropped_skb() checks:
1. the skb->protocol is set to ETH_P_CANXL which is valid (the
function does not check the actual device capabilities).
2. the length is a valid CAN XL length.
And so, sun4ican_start_xmit() receives a CAN XL frame which it is not
able to correctly handle and will thus misinterpret it as a CAN frame.
This can result in a buffer overflow. The driver will consume cf->len
as-is with no further checks on this line:
dlc = cf->len;
Here, cf->len corresponds to the flags field of the CAN XL frame. In
our previous example, we set canxl_frame->flags to 0xff. Because the
maximum expected length is 8, a buffer overflow of 247 bytes occurs a
couple line below when doing:
for (i = 0; i < dlc; i++)
writel(cf->data[i], priv->base + (dreg + i * 4));
Populate net_device_ops->ndo_change_mtu() to ensure that the
interface's MTU can not be set to anything bigger than CAN_MTU. By
fixing the root cause, this prevents the buffer overflow.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncan: sun4i_can: populate ndo_change_mtu() to prevent buffer overflow\n\nSending an PF_PACKET allows to bypass the CAN framework logic and to\ndirectly reach the xmit() function of a CAN driver. The only check\nwhich is performed by the PF_PACKET framework is to make sure that\nskb-\u003elen fits the interface\u0027s MTU.\n\nUnfortunately, because the sun4i_can driver does not populate its\nnet_device_ops-\u003endo_change_mtu(), it is possible for an attacker to\nconfigure an invalid MTU by doing, for example:\n\n $ ip link set can0 mtu 9999\n\nAfter doing so, the attacker could open a PF_PACKET socket using the\nETH_P_CANXL protocol:\n\n\tsocket(PF_PACKET, SOCK_RAW, htons(ETH_P_CANXL))\n\nto inject a malicious CAN XL frames. For example:\n\n\tstruct canxl_frame frame = {\n\t\t.flags = 0xff,\n\t\t.len = 2048,\n\t};\n\nThe CAN drivers\u0027 xmit() function are calling can_dev_dropped_skb() to\ncheck that the skb is valid, unfortunately under above conditions, the\nmalicious packet is able to go through can_dev_dropped_skb() checks:\n\n 1. the skb-\u003eprotocol is set to ETH_P_CANXL which is valid (the\n function does not check the actual device capabilities).\n\n 2. the length is a valid CAN XL length.\n\nAnd so, sun4ican_start_xmit() receives a CAN XL frame which it is not\nable to correctly handle and will thus misinterpret it as a CAN frame.\n\nThis can result in a buffer overflow. The driver will consume cf-\u003elen\nas-is with no further checks on this line:\n\n\tdlc = cf-\u003elen;\n\nHere, cf-\u003elen corresponds to the flags field of the CAN XL frame. In\nour previous example, we set canxl_frame-\u003eflags to 0xff. Because the\nmaximum expected length is 8, a buffer overflow of 247 bytes occurs a\ncouple line below when doing:\n\n\tfor (i = 0; i \u003c dlc; i++)\n\t\twritel(cf-\u003edata[i], priv-\u003ebase + (dreg + i * 4));\n\nPopulate net_device_ops-\u003endo_change_mtu() to ensure that the\ninterface\u0027s MTU can not be set to anything bigger than CAN_MTU. By\nfixing the root cause, this prevents the buffer overflow."

"value": "AV:L - Triggering requires local syscalls on the host \u2014 `socket(PF_PACKET, SOCK_RAW, htons(ETH_P_CANXL))` followed by `sendmsg()` to the can interface, reaching `sun4ican_start_xmit()` through `dev_queue_xmit()`. The bug is entirely in the TX path; a remote or adjacent CAN-bus peer is only the sink and cannot reach it.\nAC:L - The overflow is fully deterministic \u2014 `can_dropped_invalid_skb()` accepts an ETH_P_CANXL skb on a classic-CAN device, `canxl_frame.flags` is reinterpreted as `can_frame.len`, and the loop unconditionally walks up to 255 elements. No race, no memory-layout guessing, and no condition outside the attacker\u0027s control is involved.\nPR:L - The only gate is `ns_capable(net-\u003euser_ns, CAP_NET_RAW)` in `packet_create()`, which is namespaced and granted by default in common container runtimes; because a 13\u201316 byte CAN XL frame already passes the default CAN_MTU check, the CAP_NET_ADMIN MTU change is not even needed. CAN netdevs are not netns-local, so a `can0` delegated into a container/user namespace lets an otherwise unprivileged user trigger this with no real root.\nUI:N - The attacker performs every step alone \u2014 open the packet socket and send one malicious CAN XL frame to an up CAN interface. No victim action, no configuration change by an administrator, and no interaction of any kind is required.\nS:U - The out-of-bounds read and the runaway MMIO writes stay within the kernel of the same host; no VM, hypervisor, or IOMMU boundary is crossed. The vulnerable component and the impacted resources share a single security authority.\nC:H - With a minimal 13\u201316 byte skb the loop reads `cf-\u003edata[0..254]`, over-reading roughly 247 bytes of adjacent kernel heap past the packet data. That residue is pushed into the controller\u0027s registers and, with self-reception/loopback enabled, bytes beyond `skb-\u003elen` are echoed back to userspace, giving a repeatable kernel-memory disclosure primitive.\nI:H - Up to 254 attacker-influenced 32-bit stores land beyond the intended 8-byte TX buffer slot, overwriting the entire sun4i CAN register block (acceptance/readback/reserved registers) with out-of-bounds heap contents. This is a controlled out-of-bounds write that corrupts device state and, past `0x400`, writes to memory outside the ioremap mapping entirely.\nA:H - For `dlc` above 235 the write offset exceeds the `0x400` ioremap window, and since the mapping ends exactly on a page boundary the next page is the vmalloc guard page \u2014 an unmapped kernel VA store that produces an immediate oops/panic. The condition is re-triggerable at will from an unprivileged socket, and the register scribbling wedges the CAN controller even when the fault is avoided."

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: endpoint: Fix configfs group list head handling
Doing a list_del() on the epf_group field of struct pci_epf_driver in
pci_epf_remove_cfs() is not correct as this field is a list head, not
a list entry. This list_del() call triggers a KASAN warning when an
endpoint function driver which has a configfs attribute group is torn
down:

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: Fix UAF in ieee80211_scan_rx()
ieee80211_scan_rx() tries to access scan_req->flags after a
null check, but a UAF is observed when the scan is completed
and __ieee80211_scan_completed() executes, which then calls
cfg80211_scan_done() leading to the freeing of scan_req.
Since scan_req is rcu_dereference()'d, prevent the racing in
__ieee80211_scan_completed() by ensuring that from mac80211's
POV it is no longer accessed from an RCU read critical section
before we call cfg80211_scan_done().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ublk: fail to start device if queue setup is interrupted
In ublk_ctrl_start_dev(), if wait_for_completion_interruptible() is
interrupted by signal, queues aren't setup successfully yet, so we
have to fail UBLK_CMD_START_DEV, otherwise kernel oops can be triggered.
Reported by German when working on qemu-storage-deamon which requires
single thread ublk daemon.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: Fix connections leak when tlink setup failed
If the tlink setup failed, lost to put the connections, then
the module refcnt leak since the cifsd kthread not exit.
Also leak the fscache info, and for next mount with fsc, it will
print the follow errors:
CIFS: Cache volume key already in use (cifs,127.0.0.1:445,TEST)
Let's check the result of tlink setup, and do some cleanup.

Summary
In the Linux kernel, the following vulnerability has been resolved:
video: fbdev: vt8623fb: Check the size of screen before memset_io()
In the function vt8623fb_set_par(), the value of 'screen_size' is
calculated by the user input. If the user provides the improper value,
the value of 'screen_size' may larger than 'info->screen_size', which
may cause the following bug:
[ 583.339036] BUG: unable to handle page fault for address: ffffc90005000000
[ 583.339049] #PF: supervisor write access in kernel mode

Per scoring guidance, memory-corruption primitives of this class are treated as enabling high confidentiality impact when exploitation is considered.\nI:H - memset_io() writes past info-\u003escreen_size into ioremapped framebuffer memory with an attacker-controlled length, which is an out-of-bounds write and is scored as high integrity impact.\nA:H - The demonstrated impact is a kernel page fault/oops in memset_io() when the write walks off the mapped region, which is a full availability compromise of the kernel."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ibmvnic: Free rwi on reset success
Free the rwi structure in the event that the last rwi in the list
processed successfully. The logic in commit 4f408e1fa6e1 ("ibmvnic:
retry reset if there are no other resets") introduces an issue that
results in a 32 byte memory leak whenever the last rwi in the list
gets processed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/ptdump: take the memory hotplug lock inside ptdump_walk_pgd()
Memory hot remove unmaps and tears down various kernel page table regions
as required. The ptdump code can race with concurrent modifications of
the kernel page tables. When leaf entries are modified concurrently, the
dump code may log stale or inconsistent information for a VA range, but
this is otherwise not harmful.
But when intermediate levels of kernel page table are freed, the dump code
will continue to use memory that has been freed and potentially
reallocated for another purpose. In such cases, the ptdump code may
dereference bogus addresses, leading to a number of potential problems.
To avoid the above mentioned race condition, platforms such as arm64,
riscv and s390 take memory hotplug lock, while dumping kernel page table
via the sysfs interface /sys/kernel/debug/kernel_page_tables.
Similar race condition exists while checking for pages that might have
been marked W+X via /sys/kernel/debug/kernel_page_tables/check_wx_pages
which in turn calls ptdump_check_wx(). Instead of solving this race
condition again, let's just move the memory hotplug lock inside generic
ptdump_check_wx() which will benefit both the scenarios.
Drop get_online_mems() and put_online_mems() combination from all existing
platform ptdump code paths.

A malicious/compromised NFS server, or an attacker MITM\u0027ing the common unauthenticated AUTH_SYS NFS connection, controls every input needed to trigger the mismatch.\nAC:L - The attacker-controlled server simply exports a nested filesystem (distinct FSID) or referral whose capability set differs from the parent\u0027s; the stale-capability inheritance then occurs deterministically on every crossing. No race, timing, or memory-layout condition is involved.\nPR:N - No credentials or privileges on the client are needed \u2014 the malicious data comes from the remote server side, and the automount is performed by the client kernel during ordinary path traversal. Local reachability likewise requires only an unprivileged user walking into the mountpoint.\nUI:N - Automount is by definition transparent: any process, including background daemons, indexers or backup jobs, that traverses into the server-side mountpoint triggers nfs_d_automount() and the faulty clone. No distinct victim action beyond normal use of an already-mounted share is required.\nS:U - The incorrect capability state stays within the NFS client\u0027s own security authority in the client kernel; no VM, IOMMU, or sandbox boundary is crossed.\nC:L - Stale NFS_CAP_UIDGID_NOMAP causes the client to encode/interpret owner and group identities as raw numeric IDs on a filesystem that expects idmapped names, so files can be attributed to the wrong principal and exposed to the wrong local user; this is limited, bounded metadata exposure rather than arbitrary kernel memory disclosure.\nI:L - The same stale identity-mapping state means creates/chowns on the automounted filesystem can land under an incorrect owner, and inherited NFS_CAP_DELEGTIME makes the client locally manage timestamps against a server that never granted delegated timestamps. This is limited metadata/ownership corruption, not an arbitrary write or control-flow hijack.\nA:L - Inherited NFS_CAP_FS_LOCATIONS with trunking discovery makes nfs_probe_fsinfo() fail and aborts the automount, and inherited NFS_CAP_OPEN_XOR/XATTR cause OPEN and xattr operations to be rejected with NFS4ERR_NOTSUPP, rendering the crossed subtree unusable. There is no kernel crash, hang, or panic, so the loss of availability is confined to the affected mount."

Summary
In the Linux kernel, the following vulnerability has been resolved:
PM: hibernate: defer device probing when resuming from hibernation
syzbot is reporting hung task at misc_open() [1], for there is a race
window of AB-BA deadlock which involves probe_count variable. Currently
wait_for_device_probe() from snapshot_open() from misc_open() can sleep
forever with misc_mtx held if probe_count cannot become 0.
When a device is probed by hub_event() work function, probe_count is
incremented before the probe function starts, and probe_count is
decremented after the probe function completed.
There are three cases that can prevent probe_count from dropping to 0.
(a) A device being probed stopped responding (i.e. broken/malicious
hardware).
(b) A process emulating a USB device using /dev/raw-gadget interface
stopped responding for some reason.
(c) New device probe requests keeps coming in before existing device
probe requests complete.
The phenomenon syzbot is reporting is (b). A process which is holding
system_transition_mutex and misc_mtx is waiting for probe_count to become
0 inside wait_for_device_probe(), but the probe function which is called
from hub_event() work function is waiting for the processes which are
blocked at mutex_lock(&misc_mtx) to respond via /dev/raw-gadget interface.
This patch mitigates (b) by deferring wait_for_device_probe() from
snapshot_open() to snapshot_write() and snapshot_ioctl(). Please note that
the possibility of (b) remains as long as any thread which is emulating a
USB device via /dev/raw-gadget interface can be blocked by uninterruptible
blocking operations (e.g. mutex_lock()).
Please also note that (a) and (c) are not addressed. Regarding (c), we
should change the code to wait for only one device which contains the
image for resuming from hibernation. I don't know how to address (a), for
use of timeout for wait_for_device_probe() might result in loss of user
data in the image. Maybe we should require the userland to wait for the
image device before opening /dev/snapshot interface.

Currently\nwait_for_device_probe() from snapshot_open() from misc_open() can sleep\nforever with misc_mtx held if probe_count cannot become 0.\n\nWhen a device is probed by hub_event() work function, probe_count is\nincremented before the probe function starts, and probe_count is\ndecremented after the probe function completed.\n\nThere are three cases that can prevent probe_count from dropping to 0.\n\n (a) A device being probed stopped responding (i.e. broken/malicious\n hardware).\n\n (b) A process emulating a USB device using /dev/raw-gadget interface\n stopped responding for some reason.\n\n (c) New device probe requests keeps coming in before existing device\n probe requests complete.\n\nThe phenomenon syzbot is reporting is (b). A process which is holding\nsystem_transition_mutex and misc_mtx is waiting for probe_count to become\n0 inside wait_for_device_probe(), but the probe function which is called\n from hub_event() work function is waiting for the processes which are\nblocked at mutex_lock(\u0026misc_mtx) to respond via /dev/raw-gadget interface.\n\nThis patch mitigates (b) by deferring wait_for_device_probe() from\nsnapshot_open() to snapshot_write() and snapshot_ioctl(). Please note that\nthe possibility of (b) remains as long as any thread which is emulating a\nUSB device via /dev/raw-gadget interface can be blocked by uninterruptible\nblocking operations (e.g. mutex_lock()).\n\nPlease also note that (a) and (c) are not addressed. Regarding (c), we\nshould change the code to wait for only one device which contains the\nimage for resuming from hibernation. I don\u0027t know how to address (a), for\nuse of timeout for wait_for_device_probe() might result in loss of user\ndata in the image. Maybe we should require the userland to wait for the\nimage device before opening /dev/snapshot interface."

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: cacheinfo: Fix incorrect assignment of signed error value to unsigned fw_level
Though acpi_find_last_cache_level() always returned signed value and the
document states it will return any errors caused by lack of a PPTT table,
it never returned negative values before.
Commit 0c80f9e165f8 ("ACPI: PPTT: Leave the table mapped for the runtime usage")
however changed it by returning -ENOENT if no PPTT was found. The value
returned from acpi_find_last_cache_level() is then assigned to unsigned
fw_level.
It will result in the number of cache leaves calculated incorrectly as
a huge value which will then cause the following warning from __alloc_pages
as the order would be great than MAX_ORDER because of incorrect and huge
cache leaves value.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: Fix call trace with null VSI during VF reset
During stress test with attaching and detaching VF from KVM and
simultaneously changing VFs spoofcheck and trust there was a
call trace in ice_reset_vf that VF's VSI is null.

Remove WARN_ON() from check if VSI is null in ice_reset_vf.
Add "VF is already removed\n" in dev_dbg().
This WARN_ON() is unnecessary and causes call trace, despite that
call trace, driver still works. There is no need for this warn
because this piece of code is responsible for disabling VF's Tx/Rx
queues when VF is disabled, but when VF is already removed there
is no need to do reset or disable queues.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bonding: do not assume skb mac_header is set
Drivers must not assume in their ndo_start_xmit() that
skbs have their mac_header set. skb->data is all what is needed.
bonding seems to be one of the last offender as caught by syzbot:

Summary
In the Linux kernel, the following vulnerability has been resolved:
md: raid1: fix potential OOB in raid1_remove_disk()
If rddev->raid_disk is greater than mddev->raid_disks, there will be
an out-of-bounds in raid1_remove_disk(). We have already found
similar reports as follows:
1) commit d17f744e883b ("md-raid10: fix KASAN warning")
2) commit 1ebc2cec0b7d ("dm raid: fix KASAN warning in raid5_remove_disk")
Fix this bug by checking whether the "number" variable is
valid.

macvlan should enforce a minimal mtu of 68, even at link creation.
This patch avoids the current behavior (which could lead to crashes
in ipv6 stack if the link is brought up)
$ ip link add macvlan1 link eno1 mtu 8 type macvlan # This should fail !
$ ip link sh dev macvlan1
5: macvlan1@eno1: <BROADCAST,MULTICAST> mtu 8 qdisc noop
state DOWN mode DEFAULT group default qlen 1000
link/ether 02:47:6c:24:74:82 brd ff:ff:ff:ff:ff:ff
$ ip link set macvlan1 mtu 67
Error: mtu less than device minimum.
$ ip link set macvlan1 mtu 68
$ ip link set macvlan1 mtu 8
Error: mtu less than device minimum.

Summary
In the Linux kernel, the following vulnerability has been resolved:
soc: qcom: aoss: Fix refcount leak in qmp_cooling_devices_register
Every iteration of for_each_available_child_of_node() decrements
the reference count of the previous node.
When breaking early from a for_each_available_child_of_node() loop,
we need to explicitly call of_node_put() on the child node.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: Remove WARN_ON for device endpoint command timeouts
This commit addresses a rarely observed endpoint command timeout
which causes kernel panic due to warn when 'panic_on_warn' is enabled
and unnecessary call trace prints when 'panic_on_warn' is disabled.
It is seen during fast software-controlled connect/disconnect testcases.
The following is one such endpoint command timeout that we observed:
1. Connect
=======
->dwc3_thread_interrupt
->dwc3_ep0_interrupt
->configfs_composite_setup
->composite_setup
->usb_ep_queue
->dwc3_gadget_ep0_queue
->__dwc3_gadget_ep0_queue
->__dwc3_ep0_do_control_data
->dwc3_send_gadget_ep_cmd
2. Disconnect
==========
->dwc3_thread_interrupt
->dwc3_gadget_disconnect_interrupt
->dwc3_ep0_reset_state
->dwc3_ep0_end_control_data
->dwc3_send_gadget_ep_cmd
In the issue scenario, in Exynos platforms, we observed that control
transfers for the previous connect have not yet been completed and end
transfer command sent as a part of the disconnect sequence and
processing of USB_ENDPOINT_HALT feature request from the host timeout.
This maybe an expected scenario since the controller is processing EP
commands sent as a part of the previous connect. It maybe better to
remove WARN_ON in all places where device endpoint commands are sent to
avoid unnecessary kernel panic due to warn.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: Fix kernel crash during reboot when adapter is in recovery mode
If the driver detects during probe that firmware is in recovery
mode then i40e_init_recovery_mode() is called and the rest of
probe function is skipped including pci_set_drvdata(). Subsequent
i40e_shutdown() called during shutdown/reboot dereferences NULL
pointer as pci_get_drvdata() returns NULL.
To fix call pci_set_drvdata() also during entering to recovery mode.
Reproducer:
1) Lets have i40e NIC with firmware in recovery mode
2) Run reboot
Result:

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: dvb-frontends: dib7090p: fix null-ptr-deref in dib7090p_rw_on_apb()
In dib7090p_rw_on_apb, msg is controlled by user. When msg[0].buf is null and
msg[0].len is zero, former checks on msg[0].buf would be passed. If accessing
msg[0].buf[2] without sanity check, null pointer deref would happen. We add
check on msg[0].len to prevent crash. Similar issue occurs when access
msg[1].buf[0] and msg[1].buf[1].
Similar commit: commit 0ed554fd769a ("media: dvb-usb: az6027: fix null-ptr-deref in az6027_i2c_xfer()")

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: mediatek: mt8183: Add back SSPM related clocks
This reverts commit 860690a93ef23b567f781c1b631623e27190f101.
On the MT8183, the SSPM related clocks were removed claiming a lack of
usage. This however causes some issues when the driver was converted to
the new simple-probe mechanism. This mechanism allocates enough space
for all the clocks defined in the clock driver, not the highest index
in the DT binding. This leads to out-of-bound writes if their are holes
in the DT binding or the driver (due to deprecated or unimplemented
clocks). These errors can go unnoticed and cause memory corruption,
leading to crashes in unrelated areas, or nothing at all. KASAN will
detect them.
Add the SSPM related clocks back to the MT8183 clock driver to fully
implement the DT binding. The SSPM clocks are for the power management
co-processor, and should never be turned off. They are marked as such.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mfd: max77620: Fix refcount leak in max77620_initialise_fps
of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_event: Fix UAF in hci_acl_create_conn_sync
This fixes the following UFA in hci_acl_create_conn_sync where a
connection still pending is command submission (conn->state == BT_OPEN)
maybe freed, also since this also can happen with the likes of
hci_le_create_conn_sync fix it as well:

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: HCI: Fix global-out-of-bounds
To loop a variable-length array, hci_init_stage_sync(stage) considers
that stage[i] is valid as long as stage[i-1].func is valid.
Thus, the last element of stage[].func should be intentionally invalid
as hci_init0[], le_init2[], and others did.
However, amp_init1[] and amp_init2[] have no invalid element, letting
hci_init_stage_sync() keep accessing amp_init1[] over its valid range.
This patch fixes this by adding {} in the last of amp_init1[] and
amp_init2[].

Summary
In the Linux kernel, the following vulnerability has been resolved:
ftrace: Fix potential warning in trace_printk_seq during ftrace_dump
When calling ftrace_dump_one() concurrently with reading trace_pipe,
a WARN_ON_ONCE() in trace_printk_seq() can be triggered due to a race
condition.
The issue occurs because:
CPU0 (ftrace_dump) CPU1 (reader)
echo z > /proc/sysrq-trigger
!trace_empty(&iter)
trace_iterator_reset(&iter) <- len = size = 0
cat /sys/kernel/tracing/trace_pipe
trace_find_next_entry_inc(&iter)
__find_next_entry
ring_buffer_empty_cpu <- all empty
return NULL
trace_printk_seq(&iter.seq)
WARN_ON_ONCE(s->seq.len >= s->seq.size)
In the context between trace_empty() and trace_find_next_entry_inc()
during ftrace_dump, the ring buffer data was consumed by other readers.
This caused trace_find_next_entry_inc to return NULL, failing to populate
`iter.seq`. At this point, due to the prior trace_iterator_reset, both
`iter.seq.len` and `iter.seq.size` were set to 0. Since they are equal,
the WARN_ON_ONCE condition is triggered.
Move the trace_printk_seq() into the if block that checks to make sure the
return value of trace_find_next_entry_inc() is non-NULL in
ftrace_dump_one(), ensuring the 'iter.seq' is properly populated before
subsequent operations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: xilinx_can: xcan_write_frame(): fix use-after-free of transmitted SKB
can_put_echo_skb() takes ownership of the SKB and it may be freed
during or after the call.
However, xilinx_can xcan_write_frame() keeps using SKB after the call.
Fix that by only calling can_put_echo_skb() after the code is done
touching the SKB.
The tx_lock is held for the entire xcan_write_frame() execution and
also on the can_get_echo_skb() side so the order of operations does not
matter.
An earlier fix commit 3d3c817c3a40 ("can: xilinx_can: Fix usage of skb
memory") did not move the can_put_echo_skb() call far enough.

No root or CAP_NET_ADMIN is needed to reach `xcan_write_frame()`.\nUI:N - The attacker\u0027s own `sendmsg()` call drives the whole path; no victim action or cooperation is required.\nS:U - The corruption stays within the kernel\u0027s own security authority \u2014 freed kernel heap and the driver\u0027s MMIO window \u2014 with no crossing of a hypervisor, IOMMU or sandbox boundary.\nC:H - The UAF reads freed (and, with a groomed `cf-\u003elen`, out-of-bounds) kernel heap contents and writes them into the CAN controller\u0027s TX registers, which are then transmitted on the physical CAN bus where any node \u2014 including the attacker\u0027s \u2014 can read them, giving direct kernel memory disclosure.\nI:H - `cf-\u003elen` read from reclaimed memory is unbounded (up to 255), so the write loop overruns the mailbox\u0027s data window and writes attacker-influenced dwords into adjacent CAN controller registers, and a UAF of this kind is generally leverageable into heap-spray-based write primitives; it also injects arbitrary frame content onto a safety-critical bus.\nA:H - The use-after-free triggers a KASAN panic on hardened kernels, and the out-of-bounds register writes plus lost echo-SKB accounting corrupt controller state and permanently wedge the TX queue (`netif_stop_queue()` with no matching completion), producing a crash or denial of CAN service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: storvsc: Remove WQ_MEM_RECLAIM from storvsc_error_wq
storvsc_error_wq workqueue should not be marked as WQ_MEM_RECLAIM as it
doesn't need to make forward progress under memory pressure. Marking this
workqueue as WQ_MEM_RECLAIM may cause deadlock while flushing a
non-WQ_MEM_RECLAIM workqueue. In the current state it causes the following
warning:

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Unregister devlink params in case interface is down
Currently, in case an interface is down, mlx5 driver doesn't
unregister its devlink params, which leads to this WARN[1].
Fix it by unregistering devlink params in that case as well.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: sch_ets: don't peek at classes beyond 'nbands'
when the number of DRR classes decreases, the round-robin active list can
contain elements that have already been freed in ets_qdisc_change(). As a
consequence, it's possible to see a NULL dereference crash, caused by the
attempt to call cl->qdisc->ops->peek(cl->qdisc) when cl->qdisc is NULL:

Ensuring that 'alist' was never zeroed [1] was not sufficient, we need to
remove from the active list those elements that are no more SP nor DRR.

v3: fix race between ets_qdisc_change() and ets_qdisc_dequeue() delisting
DRR classes beyond 'nbands' in ets_qdisc_change() with the qdisc lock
acquired, thanks to Cong Wang.
v2: when a NULL qdisc is found in the DRR active list, try to dequeue skb
from the next list item.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ath11k: fix netdev open race
Make sure to allocate resources needed before registering the device.
This specifically avoids having a racing open() trigger a BUG_ON() in
mod_timer() when ath11k_mac_op_start() is called before the
mon_reap_timer as been set up.
I did not see this issue with next-20220310, but I hit it on every probe
with next-20220511. Perhaps some timing changed in between.
Here's the backtrace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix unsafe drain work queue code
If create_qp does not fully succeed it is possible for qp cleanup
code to attempt to drain the send or recv work queues before the
queues have been created causing a seg fault. This patch checks
to see if the queues exist before attempting to drain them.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: Avoid NULL pointer access during management transmit cleanup
Currently 'ar' reference is not added in skb_cb.
Though this is generally not used during transmit completion
callbacks, on interface removal the remaining idr cleanup callback
uses the ar pointer from skb_cb from management txmgmt_idr. Hence fill them
during transmit call for proper usage to avoid NULL pointer dereference.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: sf-pdma: Add multithread support for a DMA channel
When we get a DMA channel and try to use it in multiple threads it
will cause oops and hanging the system.
% echo 64 > /sys/module/dmatest/parameters/threads_per_chan
% echo 10000 > /sys/module/dmatest/parameters/iterations
% echo 1 > /sys/module/dmatest/parameters/run
[ 89.480664] Unable to handle kernel NULL pointer dereference at virtual
address 00000000000000a0
[ 89.488725] Oops [#1]
[ 89.494708] CPU: 2 PID: 1008 Comm: dma0chan0-copy0 Not tainted
5.17.0-rc5
[ 89.509385] epc : vchan_find_desc+0x32/0x46
[ 89.513553] ra : sf_pdma_tx_status+0xca/0xd6
This happens because of data race. Each thread rewrite channels's
descriptor as soon as device_prep_dma_memcpy() is called. It leads to the
situation when the driver thinks that it uses right descriptor that
actually is freed or substituted for other one.
With current fixes a descriptor changes its value only when it has
been used. A new descriptor is acquired from vc->desc_issued queue that
is already filled with descriptors that are ready to be sent. Threads
have no direct access to DMA channel descriptor. Now it is just possible
to queue a descriptor for further processing.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ieee802154/adf7242: defer destroy_workqueue call
There is a possible race condition (use-after-free) like below
(FREE) | (USE)
adf7242_remove | adf7242_channel
cancel_delayed_work_sync |
destroy_workqueue (1) | adf7242_cmd_rx
| mod_delayed_work (2)
|
The root cause for this race is that the upper layer (ieee802154) is
unaware of this detaching event and the function adf7242_channel can
be called without any checks.
To fix this, we can add a flag write at the beginning of adf7242_remove
and add flag check in adf7242_channel. Or we can just defer the
destructive operation like other commit 3e0588c291d6 ("hamradio: defer
ax25 kfree after unregister_netdev") which let the
ieee802154_unregister_hw() to handle the synchronization. This patch
takes the second option.

Summary
In the Linux kernel, the following vulnerability has been resolved:
kobject: Add sanity check for kset->kobj.ktype in kset_register()
When I register a kset in the following way:
static struct kset my_kset;
kobject_set_name(&my_kset.kobj, "my_kset");
ret = kset_register(&my_kset);
A null pointer dereference exception is occurred:
[ 4453.568337] Unable to handle kernel NULL pointer dereference at \
virtual address 0000000000000028
... ...
[ 4453.810361] Call trace:
[ 4453.813062] kobject_get_ownership+0xc/0x34
[ 4453.817493] kobject_add_internal+0x98/0x274
[ 4453.822005] kset_register+0x5c/0xb4
[ 4453.825820] my_kobj_init+0x44/0x1000 [my_kset]
... ...
Because I didn't initialize my_kset.kobj.ktype.
According to the description in Documentation/core-api/kobject.rst:
- A ktype is the type of object that embeds a kobject. Every structure
that embeds a kobject needs a corresponding ktype.
So add sanity check to make sure kset->kobj.ktype is not NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: Remove improper idxd_free
The call to idxd_free() introduces a duplicate put_device() leading to a
reference count underflow:
refcount_t: underflow; use-after-free.
WARNING: CPU: 15 PID: 4428 at lib/refcount.c:28 refcount_warn_saturate+0xbe/0x110
...
Call Trace:
<TASK>
idxd_remove+0xe4/0x120 [idxd]
pci_device_remove+0x3f/0xb0
device_release_driver_internal+0x197/0x200
driver_detach+0x48/0x90
bus_remove_driver+0x74/0xf0
pci_unregister_driver+0x2e/0xb0

do_syscall_64+0x54/0xd70
entry_SYSCALL_64_after_hwframe+0x76/0x7e
The idxd_unregister_devices() which is invoked at the very beginning of
idxd_remove(), already takes care of the necessary put_device() through the
following call path:
idxd_unregister_devices() -> device_unregister() -> put_device()
In addition, when CONFIG_DEBUG_KOBJECT_RELEASE is enabled, put_device() may
trigger asynchronous cleanup via schedule_delayed_work(). If idxd_free() is
called immediately after, it can result in a use-after-free.
Remove the improper idxd_free() to avoid both the refcount underflow and
potential memory corruption during module unload.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: core: Fix unremoved procfs host directory regression
Commit fc663711b944 ("scsi: core: Remove the /proc/scsi/${proc_name}
directory earlier") fixed a bug related to modules loading/unloading, by
adding a call to scsi_proc_hostdir_rm() on scsi_remove_host(). But that led
to a potential duplicate call to the hostdir_rm() routine, since it's also
called from scsi_host_dev_release(). That triggered a regression report,
which was then fixed by commit be03df3d4bfe ("scsi: core: Fix a procfs host
directory removal regression"). The fix just dropped the hostdir_rm() call
from dev_release().
But it happens that this proc directory is created on scsi_host_alloc(),
and that function "pairs" with scsi_host_dev_release(), while
scsi_remove_host() pairs with scsi_add_host(). In other words, it seems the
reason for removing the proc directory on dev_release() was meant to cover
cases in which a SCSI host structure was allocated, but the call to
scsi_add_host() didn't happen. And that pattern happens to exist in some
error paths, for example.
Syzkaller causes that by using USB raw gadget device, error'ing on
usb-storage driver, at usb_stor_probe2(). By checking that path, we can see
that the BadDevice label leads to a scsi_host_put() after a SCSI host
allocation, but there's no call to scsi_add_host() in such path. That leads
to messages like this in dmesg (and a leak of the SCSI host proc
structure):
usb-storage 4-1:87.51: USB Mass Storage device detected
proc_dir_entry 'scsi/usb-storage' already registered
WARNING: CPU: 1 PID: 3519 at fs/proc/generic.c:377 proc_register+0x347/0x4e0 fs/proc/generic.c:376
The proper fix seems to still call scsi_proc_hostdir_rm() on dev_release(),
but guard that with the state check for SHOST_CREATED; there is even a
comment in scsi_host_dev_release() detailing that: such conditional is
meant for cases where the SCSI host was allocated but there was no calls to
{add,remove}_host(), like the usb-storage case.
This is what we propose here and with that, the error path of usb-storage
does not trigger the warning anymore.

But that led\nto a potential duplicate call to the hostdir_rm() routine, since it\u0027s also\ncalled from scsi_host_dev_release(). That triggered a regression report,\nwhich was then fixed by commit be03df3d4bfe (\"scsi: core: Fix a procfs host\ndirectory removal regression\"). The fix just dropped the hostdir_rm() call\nfrom dev_release().\n\nBut it happens that this proc directory is created on scsi_host_alloc(),\nand that function \"pairs\" with scsi_host_dev_release(), while\nscsi_remove_host() pairs with scsi_add_host(). In other words, it seems the\nreason for removing the proc directory on dev_release() was meant to cover\ncases in which a SCSI host structure was allocated, but the call to\nscsi_add_host() didn\u0027t happen. And that pattern happens to exist in some\nerror paths, for example.\n\nSyzkaller causes that by using USB raw gadget device, error\u0027ing on\nusb-storage driver, at usb_stor_probe2(). By checking that path, we can see\nthat the BadDevice label leads to a scsi_host_put() after a SCSI host\nallocation, but there\u0027s no call to scsi_add_host() in such path. That leads\nto messages like this in dmesg (and a leak of the SCSI host proc\nstructure):\n\nusb-storage 4-1:87.51: USB Mass Storage device detected\nproc_dir_entry \u0027scsi/usb-storage\u0027 already registered\nWARNING: CPU: 1 PID: 3519 at fs/proc/generic.c:377 proc_register+0x347/0x4e0 fs/proc/generic.c:376\n\nThe proper fix seems to still call scsi_proc_hostdir_rm() on dev_release(),\nbut guard that with the state check for SHOST_CREATED; there is even a\ncomment in scsi_host_dev_release() detailing that: such conditional is\nmeant for cases where the SCSI host was allocated but there was no calls to\n{add,remove}_host(), like the usb-storage case.\n\nThis is what we propose here and with that, the error path of usb-storage\ndoes not trigger the warning anymore."

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfc: pn533: initialize struct pn533_out_arg properly
struct pn533_out_arg used as a temporary context for out_urb is not
initialized properly. Its uninitialized 'phy' field can be dereferenced in
error cases inside pn533_out_complete() callback function. It causes the
following failure:

Summary
In the Linux kernel, the following vulnerability has been resolved:
rcu-tasks: Avoid pr_info() with spin lock in cblist_init_generic()
pr_info() is called with rtp->cbs_gbl_lock spin lock locked. Because
pr_info() calls printk() that might sleep, this will result in BUG
like below:
[ 0.206455] cblist_init_generic: Setting adjustable number of callback queues.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btsdio: fix use after free bug in btsdio_remove due to race condition
In btsdio_probe, the data->work is bound with btsdio_work. It will be
started in btsdio_send_frame.
If the btsdio_remove runs with a unfinished work, there may be a race
condition that hdev is freed but used in btsdio_work. Fix it by
canceling the work before do cleanup in btsdio_remove.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix lockdep assertion on sync reset unload event
Fix lockdep assertion triggered during sync reset unload event. When the
sync reset flow is initiated using the devlink reload fw_activate
option, the PF already holds the devlink lock while handling unload
event. In this case, delegate sync reset unload event handling back to
the devlink callback process to avoid double-locking and resolve the
lockdep warning.
Kernel log:
WARNING: CPU: 9 PID: 1578 at devl_assert_locked+0x31/0x40
[...]

Summary
In the Linux kernel, the following vulnerability has been resolved:
ftrace: Fix null pointer dereference in ftrace_add_mod()
The @ftrace_mod is allocated by kzalloc(), so both the members {prev,next}
of @ftrace_mode->list are NULL, it's not a valid state to call list_del().
If kstrdup() for @ftrace_mod->{func|module} fails, it goes to @out_free
tag and calls free_ftrace_mod() to destroy @ftrace_mod, then list_del()
will write prev->next and next->prev, where null pointer dereference
happens.
BUG: kernel NULL pointer dereference, address: 0000000000000008
Oops: 0002 [#1] PREEMPT SMP NOPTI

Summary
In the Linux kernel, the following vulnerability has been resolved:
ceph: avoid putting the realm twice when decoding snaps fails
When decoding the snaps fails it maybe leaving the 'first_realm'
and 'realm' pointing to the same snaprealm memory. And then it'll
put it twice and could cause random use-after-free, BUG_ON, etc
issues.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvmet: avoid potential UAF in nvmet_req_complete()
An nvme target ->queue_response() operation implementation may free the
request passed as argument. Such implementation potentially could result
in a use after free of the request pointer when percpu_ref_put() is
called in nvmet_req_complete().
Avoid such problem by using a local variable to save the sq pointer
before calling __nvmet_req_complete(), thus avoiding dereferencing the
req pointer after that function call.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: reject unhashed sockets in bpf_sk_assign
The semantics for bpf_sk_assign are as follows:
sk = some_lookup_func()
bpf_sk_assign(skb, sk)
bpf_sk_release(sk)
That is, the sk is not consumed by bpf_sk_assign. The function
therefore needs to make sure that sk lives long enough to be
consumed from __inet_lookup_skb. The path through the stack for a
TCPv4 packet is roughly:
netif_receive_skb_core: takes RCU read lock
__netif_receive_skb_core:
sch_handle_ingress:
tcf_classify:
bpf_sk_assign()
deliver_ptype_list_skb:
deliver_skb:
ip_packet_type->func == ip_rcv:
ip_rcv_core:
ip_rcv_finish_core:
dst_input:
ip_local_deliver:
ip_local_deliver_finish:
ip_protocol_deliver_rcu:
tcp_v4_rcv:
__inet_lookup_skb:
skb_steal_sock
The existing helper takes advantage of the fact that everything
happens in the same RCU critical section: for sockets with
SOCK_RCU_FREE set bpf_sk_assign never takes a reference.
skb_steal_sock then checks SOCK_RCU_FREE again and does sock_put
if necessary.
This approach assumes that SOCK_RCU_FREE is never set on a sk
between bpf_sk_assign and skb_steal_sock, but this invariant is
violated by unhashed UDP sockets. A new UDP socket is created
in TCP_CLOSE state but without SOCK_RCU_FREE set. That flag is only
added in udp_lib_get_port() which happens when a socket is bound.
When bpf_sk_assign was added it wasn't possible to access unhashed
UDP sockets from BPF, so this wasn't a problem. This changed
in commit 0c48eefae712 ("sock_map: Lift socket state restriction
for datagram sockets"), but the helper wasn't adjusted accordingly.
The following sequence of events will therefore lead to a refcount
leak:
1. Add socket(AF_INET, SOCK_DGRAM) to a sockmap.
2. Pull socket out of sockmap and bpf_sk_assign it. Since
SOCK_RCU_FREE is not set we increment the refcount.
3. bind() or connect() the socket, setting SOCK_RCU_FREE.
4. skb_steal_sock will now set refcounted = false due to
SOCK_RCU_FREE.
5. tcp_v4_rcv() skips sock_put().
Fix the problem by rejecting unhashed sockets in bpf_sk_assign().
This matches the behaviour of __inet_lookup_skb which is ultimately
the goal of bpf_sk_assign().

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: install stub fence into potential unused fence pointers
When using cpu to update page tables, vm update fences are unused.
Install stub fence into these fence pointers instead of NULL
to avoid NULL dereference when calling dma_fence_wait() on them.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/ttm: Fix a NULL pointer dereference
The LRU mechanism may look up a resource in the process of being removed
from an object. The locking rules here are a bit unclear but it looks
currently like res->bo assignment is protected by the LRU lock, whereas
bo->resource is protected by the object lock, while *clearing* of
bo->resource is also protected by the LRU lock. This means that if
we check that bo->resource points to the LRU resource under the LRU
lock we should be safe.
So perform that check before deciding to swap out a bo. That avoids
dereferencing a NULL bo->resource in ttm_bo_swapout().

Summary
In the Linux kernel, the following vulnerability has been resolved:
netlink: Fix wraparounds of sk->sk_rmem_alloc.
Netlink has this pattern in some places
if (atomic_read(&sk->sk_rmem_alloc) > sk->sk_rcvbuf)
atomic_add(skb->truesize, &sk->sk_rmem_alloc);
, which has the same problem fixed by commit 5a465a0da13e ("udp:
Fix multiple wraparounds of sk->sk_rmem_alloc.").
For example, if we set INT_MAX to SO_RCVBUFFORCE, the condition
is always false as the two operands are of int.
Then, a single socket can eat as many skb as possible until OOM
happens, and we can see multiple wraparounds of sk->sk_rmem_alloc.
Let's fix it by using atomic_add_return() and comparing the two
variables as unsigned int.
Before:
[root@fedora ~]# ss -f netlink
Recv-Q Send-Q Local Address:Port Peer Address:Port
-1668710080 0 rtnl:nl_wraparound/293 *
After:
[root@fedora ~]# ss -f netlink
Recv-Q Send-Q Local Address:Port Peer Address:Port
2147483072 0 rtnl:nl_wraparound/290 *
^
`--- INT_MAX - 576

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/sclp: Fix SCCB present check
Tracing code called by the SCLP interrupt handler contains early exits
if the SCCB address associated with an interrupt is NULL. This check is
performed after physical to virtual address translation.
If the kernel identity mapping does not start at address zero, the
resulting virtual address is never zero, so that the NULL checks won't
work. Subsequently this may result in incorrect accesses to the first
page of the identity mapping.
Fix this by introducing a function that handles the NULL case before
address translation.

There is no network or adjacent-network attack surface.\nAC:L - On an affected kernel with a non-zero identity base (the default on v6.10\u2013v6.11-rc4 with KASLR, and selectable thereafter), every event-pending SCLP interrupt deterministically defeats the NULL guards \u2014 nothing depends on memory layout, timing, or any condition outside the attacker\u0027s influence. No race must be won and no rare precondition beyond kernel configuration is involved.\nPR:L - No capability check, credential, or privileged gate exists anywhere on the path \u2014 the faulty dereference occurs unconditionally in the interrupt handler during normal system operation, so an ordinary local account on the affected LPAR/guest suffices to be present when it fires and to drive SCLP event traffic. Real root in the initial namespace is not required for the bug to be exercised.\nUI:N - The SCLP external interrupt is delivered asynchronously by the machine and the bad dereference happens entirely inside the interrupt handler. No victim must open a file, mount anything, or take any action.\nS:U - The kernel reads the wrong kernel-side address and writes into its own debug trace areas; the impact is confined to the kernel\u0027s own security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - `sclp_trace_bin()` uses a length field read from the wrong page, so `debug_event_common()` loops and copies up to 65535 bytes of out-of-bounds kernel memory \u2014 starting at the running CPU\u0027s lowcore, which holds `current_task`, kernel/async/restart stack pointers, ASCEs, per-CPU offset and saved PSWs/registers \u2014 into the `sclp`/`sclp_err` trace areas and any resulting dump. This is a large unbounded-in-practice kernel read that defeats KASLR and exposes pointers, far beyond a \"few bytes\" bounded leak.\nI:L - There is no arbitrary or out-of-bounds write primitive; the corruption is confined to kernel diagnostic state \u2014 thousands of bogus entries per interrupt wipe the entire SCLP error-trace ring buffer and every affected interrupt is falsely flagged as an error, destroying legitimate service-call diagnostic history. That is real but limited modification of kernel data.\nA:H - Once the companion change `93f616ff870a1f` leaves the first two pages of the identity mapping unmapped, `__va(0)` becomes an invalid address and the deref raises an addressing exception inside an external-interrupt handler holding `sclp_lock`, producing a kernel oops/panic; even where the page is mapped, the garbage `sccb-\u003elength` forces up to ~4096 `debug_event()` iterations per interrupt under a raw spinlock in IRQ context, adding sustained interrupt-latency degradation on the console path."

Summary
In the Linux kernel, the following vulnerability has been resolved:
qed: Don't collect too many protection override GRC elements
In the protection override dump path, the firmware can return far too
many GRC elements, resulting in attempting to write past the end of the
previously-kmalloc'ed dump buffer.
This will result in a kernel panic with reason:
BUG: unable to handle kernel paging request at ADDRESS
where "ADDRESS" is just past the end of the protection override dump
buffer. The start address of the buffer is:
p_hwfn->cdev->dbg_features[DBG_FEATURE_PROTECTION_OVERRIDE].dump_buf
and the size of the buffer is buf_size in the same data structure.
The panic can be arrived at from either the qede Ethernet driver path:
[exception RIP: qed_grc_dump_addr_range+0x108]

qed_dbg_protection_override_dump at ffffffffc0267792 [qed]

or the qedf storage driver path:

Resolve this by clamping the firmware's return value to the maximum
number of legal elements the firmware should return.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netlink: avoid infinite retry looping in netlink_unicast()
netlink_attachskb() checks for the socket's read memory allocation
constraints. Firstly, it has:
rmem < READ_ONCE(sk->sk_rcvbuf)
to check if the just increased rmem value fits into the socket's receive
buffer. If not, it proceeds and tries to wait for the memory under:
rmem + skb->truesize > READ_ONCE(sk->sk_rcvbuf)
The checks don't cover the case when skb->truesize + sk->sk_rmem_alloc is
equal to sk->sk_rcvbuf. Thus the function neither successfully accepts
these conditions, nor manages to reschedule the task - and is called in
retry loop for indefinite time which is caught as:
rcu: INFO: rcu_sched self-detected stall on CPU

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ena: fix shift-out-of-bounds in exponential backoff
The ENA adapters on our instances occasionally reset. Once recently
logged a UBSAN failure to console in the process:
UBSAN: shift-out-of-bounds in build/linux/drivers/net/ethernet/amazon/ena/ena_com.c:540:13
shift exponent 32 is too large for 32-bit type 'unsigned int'
CPU: 28 PID: 70012 Comm: kworker/u72:2 Kdump: loaded not tainted 5.15.117
Hardware name: Amazon EC2 c5d.9xlarge/, BIOS 1.0 10/16/2017

</TASK>
Apparently, the reset delays are getting so large they can trigger a
UBSAN panic.
Looking at the code, the current timeout is capped at 5000us. Using a
base value of 100us, the current code will overflow after (1<<29). Even
at values before 32, this function wraps around, perhaps
unintentionally.
Cap the value of the exponent used for this backoff at (1<<16) which is
larger than currently necessary, but large enough to support bigger
values in the future.

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: entry: avoid kprobe recursion
The cortex_a76_erratum_1463225_debug_handler() function is called when
handling debug exceptions (and synchronous exceptions from BRK
instructions), and so is called when a probed function executes. If the
compiler does not inline cortex_a76_erratum_1463225_debug_handler(), it
can be probed.
If cortex_a76_erratum_1463225_debug_handler() is probed, any debug
exception or software breakpoint exception will result in recursive
exceptions leading to a stack overflow. This can be triggered with the
ftrace multiple_probes selftest, and as per the example splat below.
This is a regression caused by commit:
6459b8469753e9fe ("arm64: entry: consolidate Cortex-A76 erratum 1463225 workaround")
... which removed the NOKPROBE_SYMBOL() annotation associated with the
function.
My intent was that cortex_a76_erratum_1463225_debug_handler() would be
inlined into its caller, el1_dbg(), which is marked noinstr and cannot
be probed. Mark cortex_a76_erratum_1463225_debug_handler() as
__always_inline to ensure this.
Example splat prior to this patch (with recursive entries elided):
| # echo p cortex_a76_erratum_1463225_debug_handler > /sys/kernel/debug/tracing/kprobe_events
| # echo p do_el0_svc >> /sys/kernel/debug/tracing/kprobe_events
| # echo 1 > /sys/kernel/debug/tracing/events/kprobes/enable

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: fix netdevice reference leaks in attach_default_qdiscs()
In attach_default_qdiscs(), if a dev has multiple queues and queue 0 fails
to attach qdisc because there is no memory in attach_one_default_qdisc().
Then dev->qdisc will be noop_qdisc by default. But the other queues may be
able to successfully attach to default qdisc.
In this case, the fallback to noqueue process will be triggered. If the
original attached qdisc is not released and a new one is directly
attached, this will cause netdevice reference leaks.
The following is the bug log:
veth0: default qdisc (fq_codel) fail, fallback to noqueue
unregister_netdevice: waiting for veth0 to become free. Usage count = 32
leaked reference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: u_audio: don't let userspace block driver unbind
In the unbind callback for f_uac1 and f_uac2, a call to snd_card_free()
via g_audio_cleanup() will disconnect the card and then wait for all
resources to be released, which happens when the refcount falls to zero.
Since userspace can keep the refcount incremented by not closing the
relevant file descriptor, the call to unbind may block indefinitely.
This can cause a deadlock during reboot, as evidenced by the following
blocked task observed on my machine:
task:reboot state:D stack:0 pid:2827 ppid:569 flags:0x0000000c
Call trace:
__switch_to+0xc8/0x140

__do_sys_reboot+0xcc/0x1ec
__arm64_sys_reboot+0x28/0x30
invoke_syscall+0x4c/0x110
...
The issue can also be observed by opening the card with arecord and
then stopping the process through the shell before unbinding:
# arecord -D hw:UAC2Gadget -f S32_LE -c 2 -r 48000 /dev/null
Recording WAVE '/dev/null' : Signed 32 bit Little Endian, Rate 48000 Hz, Stereo
^Z[1]+ Stopped arecord -D hw:UAC2Gadget -f S32_LE -c 2 -r 48000 /dev/null
# echo gadget.0 > /sys/bus/gadget/drivers/configfs-gadget/unbind
(observe that the unbind command never finishes)
Fix the problem by using snd_card_free_when_closed() instead, which will
still disconnect the card as desired, but defer the task of freeing the
resources to the core once userspace closes its file descriptor.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iavf: Fix NULL pointer dereference in iavf_get_link_ksettings
Fix possible NULL pointer dereference, due to freeing of adapter->vf_res
in iavf_init_get_resources. Previous commit introduced a regression,
where receiving IAVF_ERR_ADMIN_QUEUE_NO_WORK from iavf_get_vf_config

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: cdg: allow tcp_cdg_release() to be called multiple times
Apparently, mptcp is able to call tcp_disconnect() on an already
disconnected flow. This is generally fine, unless current congestion
control is CDG, because it might trigger a double-free [1]
Instead of fixing MPTCP, and future bugs, we can make tcp_disconnect()
more resilient.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: xsk: Fix crash on regular rq reactivation
When the regular rq is reactivated after the XSK socket is closed
it could be reading stale cqes which eventually corrupts the rq.
This leads to no more traffic being received on the regular rq and a
crash on the next close or deactivation of the rq.
Kal Cuttler Conely reported this issue as a crash on the release
path when the xdpsock sample program is stopped (killed) and restarted
in sequence while traffic is running.
This patch flushes all cqes when during the rq flush. The cqe flushing
is done in the reset state of the rq. mlx5e_rq_to_ready code is moved
into the flush function to allow for this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers/perf: hisi: Don't migrate perf to the CPU going to teardown
The driver needs to migrate the perf context if the current using CPU going
to teardown. By the time calling the cpuhp::teardown() callback the
cpu_online_mask() hasn't updated yet and still includes the CPU going to
teardown. In current driver's implementation we may migrate the context
to the teardown CPU and leads to the below calltrace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: add validation for ring_len param
The `ring_len` parameter provided by the virtual function (VF)
is assigned directly to the hardware memory context (HMC) without
any validation.
To address this, introduce an upper boundary check for both Tx and Rx
queue lengths. The maximum number of descriptors supported by the
hardware is 8k-32.
Additionally, enforce alignment constraints: Tx rings must be a multiple
of 8, and Rx rings must be a multiple of 32.

"value": "AV:L - The vulnerability is triggered by a virtchnl `VIRTCHNL_OP_CONFIG_VSI_QUEUES` mailbox message sent by the VF driver over the PCIe admin queue, not by network traffic; the attacker needs local access to a guest VM or host process that owns an SR-IOV VF. This is the standard local guest-to-host device-passthrough attack path.\nAC:L - Exploitation is fully deterministic \u2014 the attacker simply emits one CONFIG_VSI_QUEUES message with a misaligned or oversized `ring_len` and the value is programmed into the HMC context unconditionally. There is no race, no timing window, and no dependence on memory layout the attacker cannot influence.\nPR:L - The attacker holds no privileges on the vulnerable component (the host PF driver) \u2014 only control of an assigned VF, which is exactly what an ordinary untrusted cloud tenant or container is granted. No trusted-VF check gates this opcode in `i40e_vc_process_vf_msg()`, so a normally provisioned, untrusted VF owner suffices.\nUI:N - The malicious virtchnl message is processed by the PF asynchronously from the admin receive queue with no action by the host administrator or any other user. No victim interaction is involved at any point.\nS:C - The attacking component is the VF under guest/tenant authority, while the impacted resources are the host-owned HMC hardware context, the shared physical NIC, and every other VF on the adapter \u2014 a guest-to-host boundary crossing analogous to a VM escape. Corruption of PF-managed hardware state propagates outside the attacker\u0027s security authority to the host and co-tenants.\nC:H - A qlen larger than the memory actually backing the descriptor ring makes the NIC fetch descriptors past the end of the allocated region, and in deployments without IOMMU isolation (vfio-pci noiommu/DPDK, `iommu=pt`, embedded platforms) that is a device-mediated out-of-bounds read of host physical memory. The 13-bit truncation additionally desynchronizes hardware and driver views of the ring, exposing stale descriptor and packet contents.\nI:H - The same unbounded qlen drives Rx descriptor writeback and Tx head writeback to addresses beyond the intended ring, yielding attacker-influenced DMA writes outside the allocated buffer, again unconstrained where the VF is not behind an IOMMU. It also lets an untrusted VF corrupt host-managed hardware queue state on an adapter shared with other tenants.\nA:H - Out-of-spec values (misaligned, or above the 8160-descriptor hardware maximum, or truncated by the 13-bit field) produce HMC error interrupts, DMA/IOMMU faults, queue hangs and PF-level resets that take down the entire physical NIC along with the host\u0027s own networking and all other VFs. The message can be replayed indefinitely from the guest, making it a persistent cross-tenant denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: tap: NULL pointer derefence in dev_parse_header_protocol when skb->dev is null
Fixes a NULL pointer derefence bug triggered from tap driver.
When tap_get_user calls virtio_net_hdr_to_skb the skb->dev is null
(in tap.c skb->dev is set after the call to virtio_net_hdr_to_skb)
virtio_net_hdr_to_skb calls dev_parse_header_protocol which
needs skb->dev field to be valid.
The line that trigers the bug is in dev_parse_header_protocol
(dev is at offset 0x10 from skb and is stored in RAX register)
if (!dev->header_ops || !dev->header_ops->parse_protocol)
22e1: mov 0x10(%rbx),%rax
22e5: mov 0x230(%rax),%rax
Setting skb->dev before the call in tap.c fixes the issue.
BUG: kernel NULL pointer dereference, address: 0000000000000230

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/siw: Fix duplicated reported IW_CM_EVENT_CONNECT_REPLY event
If siw_recv_mpa_rr returns -EAGAIN, it means that the MPA reply hasn't
been received completely, and should not report IW_CM_EVENT_CONNECT_REPLY
in this case. This may trigger a call trace in iw_cm. A simple way to
trigger this:
server: ib_send_lat
client: ib_send_lat -R <server_ip>
The call trace looks like this:
kernel BUG at drivers/infiniband/core/iwcm.c:894!
invalid opcode: 0000 [#1] PREEMPT SMP NOPTI
<...>
Workqueue: iw_cm_wq cm_work_handler [iw_cm]

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mwifiex: Initialize the chan_stats array to zero
The adapter->chan_stats[] array is initialized in
mwifiex_init_channel_scan_gap() with vmalloc(), which doesn't zero out
memory. The array is filled in mwifiex_update_chan_statistics()
and then the user can query the data in mwifiex_cfg80211_dump_survey().
There are two potential issues here. What if the user calls
mwifiex_cfg80211_dump_survey() before the data has been filled in.
Also the mwifiex_update_chan_statistics() function doesn't necessarily
initialize the whole array. Since the array was not initialized at
the start that could result in an information leak.
Also this array is pretty small. It's a maximum of 900 bytes so it's
more appropriate to use kcalloc() instead vmalloc().

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla4xxx: Add length check when parsing nlattrs
There are three places that qla4xxx parses nlattrs:
- qla4xxx_set_chap_entry()
- qla4xxx_iface_set_param()
- qla4xxx_sysfs_ddb_set_param()
and each of them directly converts the nlattr to specific pointer of
structure without length checking. This could be dangerous as those
attributes are not validated and a malformed nlattr (e.g., length 0) could
result in an OOB read that leaks heap dirty data.
Add the nla_len check before accessing the nlattr data and return EINVAL if
the length check fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
igb: Fix igb_down hung on surprise removal
In a setup where a Thunderbolt hub connects to Ethernet and a display
through USB Type-C, users may experience a hung task timeout when they
remove the cable between the PC and the Thunderbolt hub.
This is because the igb_down function is called multiple times when
the Thunderbolt hub is unplugged. For example, the igb_io_error_detected
triggers the first call, and the igb_remove triggers the second call.
The second call to igb_down will block at napi_synchronize.
Here's the call trace:

In this case, igb_io_error_detected detaches the network interface
and requests a PCIE slot reset, however, the PCIE reset callback is
not being invoked and thus the Ethernet connection breaks down.
As the PCIE error in this case is a non-fatal one, requesting a
slot reset can be avoided.
This patch fixes the task hung issue and preserves Ethernet
connection by ignoring non-fatal PCIE errors.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipmi_si: fix a memleak in try_smi_init()
Kmemleak reported the following leak info in try_smi_init():
unreferenced object 0xffff00018ecf9400 (size 1024):
comm "modprobe", pid 2707763, jiffies 4300851415 (age 773.308s)

[<0000000030a59039>] el0_sync+0x160/0x180
The problem was that when an error occurred before handlers registration
and after allocating `new_smi->si_sm`, the variable wouldn't be freed in
the error handling afterwards since `shutdown_smi()` hadn't been
registered yet. Fix it by adding a `kfree()` in the error handling path
in `try_smi_init()`.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_set_rbtree: fix overlap expiration walk
The lazy gc on insert that should remove timed-out entries fails to release
the other half of the interval, if any.
Can be reproduced with tests/shell/testcases/sets/0044interval_overlap_0
in nftables.git and kmemleak enabled kernel.
Second bug is the use of rbe_prev vs. prev pointer.
If rbe_prev() returns NULL after at least one iteration, rbe_prev points
to element that is not an end interval, hence it should not be removed.
Lastly, check the genmask of the end interval if this is active in the
current generation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xsk: Fix xsk_diag use-after-free error during socket cleanup
Fix a use-after-free error that is possible if the xsk_diag interface
is used after the socket has been unbound from the device. This can
happen either due to the socket being closed or the device
disappearing. In the early days of AF_XDP, the way we tested that a
socket was not bound to a device was to simply check if the netdevice
pointer in the xsk socket structure was NULL. Later, a better system
was introduced by having an explicit state variable in the xsk socket
struct. For example, the state of a socket that is on the way to being
closed and has been unbound from the device is XSK_UNBOUND.
The commit in the Fixes tag below deleted the old way of signalling
that a socket is unbound, setting dev to NULL. This in the belief that
all code using the old way had been exterminated. That was
unfortunately not true as the xsk diagnostics code was still using the
old way and thus does not work as intended when a socket is going
down. Fix this by introducing a test against the state variable. If
the socket is in the state XSK_UNBOUND, simply abort the diagnostic's
netlink operation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
intel_th: msu: Fix vmalloced buffers
After commit f5ff79fddf0e ("dma-mapping: remove CONFIG_DMA_REMAP") there's
a chance of DMA buffer getting allocated via vmalloc(), which messes up
the mmapping code:
> RIP: msc_mmap_fault [intel_th_msu]
> Call Trace:
> <TASK>
> __do_fault
> do_fault
...
Fix this by accounting for vmalloc possibility.

Summary
In the Linux kernel, the following vulnerability has been resolved:
skbuff: skb_segment, Call zero copy functions before using skbuff frags
Commit bf5c25d60861 ("skbuff: in skb_segment, call zerocopy functions
once per nskb") added the call to zero copy functions in skb_segment().
The change introduced a bug in skb_segment() because skb_orphan_frags()
may possibly change the number of fragments or allocate new fragments
altogether leaving nrfrags and frag to point to the old values. This can
cause a panic with stacktrace like the one below.
[ 193.894380] BUG: kernel NULL pointer dereference, address: 00000000000000bc

In this case calling skb_orphan_frags() updated nr_frags leaving nrfrags
local variable in skb_segment() stale. This resulted in the code hitting
i >= nrfrags prematurely and trying to move to next frag_skb using
list_skb pointer, which was NULL, and caused kernel panic. Move the call
to zero copy functions before using frags and nr_frags.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: prevent use-after-free by freeing the cfile later
In smb2_compound_op we have a possible use-after-free
which can cause hard to debug problems later on.
This was revealed during stress testing with KASAN enabled
kernel. Fixing it by moving the cfile free call to
a few lines below, after the usage.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Fix an illegal memory access
In the kfd_wait_on_events() function, the kfd_event_waiter structure is
allocated by alloc_event_waiters(), but the event field of the waiter
structure is not initialized; When copy_from_user() fails in the
kfd_wait_on_events() function, it will enter exception handling to
release the previously allocated memory of the waiter structure;
Due to the event field of the waiters structure being accessed
in the free_waiters() function, this results in illegal memory access
and system crash, here is the crash log:

Summary
In the Linux kernel, the following vulnerability has been resolved:
iavf: Fix use-after-free in free_netdev
We do netif_napi_add() for all allocated q_vectors[], but potentially
do netif_napi_del() for part of them, then kfree q_vectors and leave
invalid pointers at dev->napi_list.

"lang": "en",
"value": "AV:L - The vulnerable state is created through local device-management interfaces \u2014 the `ethtool -L` (ETHTOOL_SCHANNELS) ioctl on the VF netdev and sysfs/PCI-unbind driver teardown \u2014 and no virtchnl message or received network packet reaches `iavf_free_q_vectors()`. Exploitation therefore requires local access to the system hosting the iavf VF.\nAC:L - The attacker controls both sides of the race described in the commit\u0027s own reproducer, issuing the queue-count reconfiguration and driving the VF reset/teardown loop themselves, and can repeat both indefinitely until `iavf_set_channels()` takes its reset-timeout path that lowers `num_active_queues`. Heap grooming of the freed 8192-byte object before `free_netdev()` is likewise under attacker influence.\nPR:L - Reaching `iavf_set_channels()` only needs `ns_capable(net-\u003euser_ns, CAP_NET_ADMIN)`, which a container or tenant holds over its own network namespace when an SR-IOV VF is delegated into it \u2014 a routine Kubernetes SR-IOV CNI / NFV deployment. No real root in the initial namespace is required to create the NAPI add/del mismatch.\nUI:N - No victim action is needed; the attacker triggers the queue reconfiguration, the resets, and the driver-teardown path themselves in a loop, exactly as in the commit\u0027s reproducer script. Stale `napi_struct` entries also persist on a live `netdev-\u003enapi_list` after a reinit, so no separate administrator action is required.\nS:U - The use-after-free corrupts kernel heap memory and is exploited entirely within the kernel\u0027s own security authority, giving kernel-level control on the same host. No hypervisor, IOMMU, or other security-authority boundary is crossed.\nC:H - The dangling `napi_struct` pointers reference a freed `kmalloc-8k` object that the attacker can reoccupy with sprayed data, and `__netif_napi_del()` reads `napi-\u003estate`, `napi-\u003edev_list`, `napi-\u003eskb`, `napi-\u003egro_hash[]`, and `napi-\u003ethread` from it. Combined with the resulting arbitrary-pointer dereferences, this is leverageable into arbitrary kernel memory disclosure.\nI:H - `__netif_napi_del()` performs `list_del_rcu(\u0026napi-\u003edev_list)` and `hlist_del_init_rcu()` on the freed object, writing to attacker-forged `next`/`prev` pointers \u2014 a direct arbitrary-write primitive \u2014 plus `kfree_skb()` on controlled `napi-\u003eskb`/GRO-hash pointers and `kthread_stop(napi-\u003ethread)`. These are sufficient for control-flow hijacking and full privilege escalation.\nA:H - Even without exploitation the use-after-free corrupts `netdev-\u003enapi_list` and reliably oopses in `free_netdev()`, as shown by the KASAN splat in the commit message. Any list-walk consumer (`free_netdev()`, `netif_set_threaded()`, `__netpoll_setup()`) can panic the kernel."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: update s_journal_inum if it changes after journal replay
When mounting a crafted ext4 image, s_journal_inum may change after journal
replay, which is obviously unreasonable because we have successfully loaded
and replayed the journal through the old s_journal_inum. And the new
s_journal_inum bypasses some of the checks in ext4_get_journal(), which
may trigger a null pointer dereference problem. So if s_journal_inum
changes after the journal replay, we ignore the change, and rewrite the
current journal_inum to the superblock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
siox: fix possible memory leak in siox_device_add()
If device_register() returns error in siox_device_add(),
the name allocated by dev_set_name() need be freed. As
comment of device_register() says, it should use put_device()
to give up the reference in the error path. So fix this
by calling put_device(), then the name can be freed in
kobject_cleanup(), and sdevice is freed in siox_device_release(),
set it to null in error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
memstick/ms_block: Fix a memory leak
'erased_blocks_bitmap' is never freed. As it is allocated at the same time
as 'used_blocks_bitmap', it is likely that it should be freed also at the
same time.
Add the corresponding bitmap_free() in msb_data_clear().

Summary
In the Linux kernel, the following vulnerability has been resolved:
pstore/ram: Check start of empty przs during init
After commit 30696378f68a ("pstore/ram: Do not treat empty buffers as
valid"), initialization would assume a prz was valid after seeing that
the buffer_size is zero (regardless of the buffer start position). This
unchecked start value means it could be outside the bounds of the buffer,
leading to future access panics when written to:
sysdump_panic_event+0x3b4/0x5b8
atomic_notifier_call_chain+0x54/0x90
panic+0x1c8/0x42c
die+0x29c/0x2a8
die_kernel_fault+0x68/0x78
__do_kernel_fault+0x1c4/0x1e0
do_bad_area+0x40/0x100
do_translation_fault+0x68/0x80
do_mem_abort+0x68/0xf8
el1_da+0x1c/0xc0
__raw_writeb+0x38/0x174
__memcpy_toio+0x40/0xac
persistent_ram_update+0x44/0x12c
persistent_ram_write+0x1a8/0x1b8
ramoops_pstore_write+0x198/0x1e8
pstore_console_write+0x94/0xe0
...
To avoid this, also check if the prz start is 0 during the initialization
phase. If not, the next prz sanity check case will discover it (start >
size) and zap the buffer back to a sane state.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vdpa: Add max vqp attr to vdpa_nl_policy for nlattr length check
The vdpa_nl_policy structure is used to validate the nlattr when parsing
the incoming nlmsg. It will ensure the attribute being described produces
a valid nlattr pointer in info->attrs before entering into each handler
in vdpa_nl_ops.
That is to say, the missing part in vdpa_nl_policy may lead to illegal
nlattr after parsing, which could lead to OOB read just like CVE-2023-3773.
This patch adds the missing nla_policy for vdpa max vqp attr to avoid
such bugs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/qedr: Fix potential memory leak in __qedr_alloc_mr()
__qedr_alloc_mr() allocates a memory chunk for "mr->info.pbl_table" with
init_mr_info(). When rdma_alloc_tid() and rdma_register_tid() fail, "mr"
is released while "mr->info.pbl_table" is not released, which will lead
to a memory leak.
We should release the "mr->info.pbl_table" with qedr_free_pbl() when error
occurs to fix the memory leak.

The absence of a maintainer reproducer reflects effort not spent, not a condition outside attacker control \u2014 the identical primitive in the companion commit 3df275ef0a6a had a reliable reproducer.\nPR:L - The rtnetlink handlers gate on netlink_net_capable(skb, CAP_NET_ADMIN), which is evaluated against the caller\u0027s netns user_ns, so an unprivileged user obtains it simply with `unshare -Urn` and can then create a dummy/veth device plus the full hfsc+netem hierarchy. No real root in the init namespace is needed.\nUI:N - The attacker performs the entire sequence \u2014 qdisc/class setup, packet transmission, and class deletion \u2014 from their own process. No victim action is involved.\nS:U - The corruption stays within the kernel\u0027s own memory and privilege domain, yielding standard local privilege escalation rather than crossing into another security authority such as a hypervisor or IOMMU boundary.\nC:H - The freed struct hfsc_class remains linked in the scheduler\u0027s eligible rbtree and is subsequently dereferenced, so a heap spray of the kmalloc-1k slot lets the attacker read back kernel data through the reclaimed object and its cl-\u003eqdisc pointer chain, giving effectively arbitrary kernel memory disclosure.\nI:H - After the free, hfsc_dequeue() performs an indirect call via qdisc_dequeue_peeked() through sch-\u003edequeue read from the reclaimed object, plus bstats_update() writes and rb_erase()/rb_insert_color() on attacker-controlled node pointers \u2014 a direct control-flow hijack and arbitrary-write primitive leading to full kernel compromise.\nA:H - Even without successful heap grooming, traversing and erasing a freed rbtree node and calling through a stale function pointer reliably produces a kernel oops/panic, and the attacker can trigger it repeatedly for a complete denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
afs: Fix potential null pointer dereference in afs_put_server
afs_put_server() accessed server->debug_id before the NULL check, which
could lead to a null pointer dereference. Move the debug_id assignment,
ensuring we never dereference a NULL server pointer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dma-buf/dma-resv: check if the new fence is really later
Previously when we added a fence to a dma_resv object we always
assumed the the newer than all the existing fences.
With Jason's work to add an UAPI to explicit export/import that's not
necessary the case any more. So without this check we would allow
userspace to force the kernel into an use after free error.
Since the change is very small and defensive it's probably a good
idea to backport this to stable kernels as well just in case others
are using the dma_resv object in the same way.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: increase scan_ies_len for S1G
Currently the S1G capability element is not taken into account
for the scan_ies_len, which leads to a buffer length validation
failure in ieee80211_prep_hw_scan() and subsequent WARN in
__ieee80211_start_scan(). This prevents hw scanning from functioning.
To fix ensure we accommodate for the S1G capability length.

No remote or adjacent peer input is involved in triggering the undersized-buffer condition.\nAC:L - The miscalculation is deterministic: on any S1G-capable hardware doing a hardware scan, `ieee80211_build_preq_ies()` always overruns the `scan_ies_len` budget and fails, firing the WARN and passing an uninitialized request to the driver every single time. No race, timing, or memory-layout condition is required.\nPR:L - `NL80211_CMD_TRIGGER_SCAN` is gated by `GENL_UNS_ADMIN_PERM`, i.e. `ns_capable(net-\u003euser_ns, CAP_NET_ADMIN)`, which is the user-namespace-aware check and therefore reachable by a low-privileged local user rather than requiring real root; in practice scans are also driven continuously by wpa_supplicant/NetworkManager on behalf of ordinary desktop users.\nUI:N - No victim action is needed \u2014 a scan request alone triggers the path, and on affected hardware normal automatic scanning at boot or after connection loss hits it with no user involvement at all.\nS:U - The uninitialized-value use and the WARN both occur within the kernel\u0027s own security authority in net/mac80211 and the wireless driver; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Because `ieee80211_prep_hw_scan()` returns before assigning `req.ie_len`/`req.mac_addr`/`req.mac_addr_mask` yet `__ieee80211_start_scan()` still calls `drv_hw_scan()`, drivers copy `req-\u003eie_len` bytes (uninitialized kmalloc heap value, effectively unbounded) out of the IE buffer into a probe request that is transmitted over the air, disclosing arbitrary adjacent kernel heap memory.\nI:N - All IE emission is bounds-checked via `skb_tailroom()`/`end - pos` guards, so no out-of-bounds write or kernel data modification occurs; the uninitialized length yields only reads.\nA:H - `WARN_ON(!ieee80211_prep_hw_scan())` fires on every scan attempt, which is a kernel panic on the many hardened/embedded builds running `panic_on_warn`, and the subsequent unbounded read driven by the uninitialized `ie_len` can fault or trigger an enormous allocation; hardware scanning is rendered permanently non-functional."

In the Linux kernel, the following vulnerability has been resolved:
firmware_loader: Fix memory leak in firmware upload
In the case of firmware-upload, an instance of struct fw_upload is
allocated in firmware_upload_register(). This data needs to be freed
in fw_dev_release(). Create a new fw_upload_free() function in
sysfs_upload.c to handle the firmware-upload specific memory frees
and incorporate the missing kfree call for the fw_upload structure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: dp: Change logging to dev for mtk_dp_aux_transfer()
Change logging from drm_{err,info}() to dev_{err,info}() in functions
mtk_dp_aux_transfer() and mtk_dp_aux_do_transfer(): this will be
essential to avoid getting NULL pointer kernel panics if any kind
of error happens during AUX transfers happening before the bridge
is attached.
This may potentially start happening in a later commit implementing
aux-bus support, as AUX transfers will be triggered from the panel
driver (for EDID) before the mtk-dp bridge gets attached, and it's
done in preparation for the same.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Squashfs: fix uninit-value in squashfs_get_parent
Syzkaller reports a "KMSAN: uninit-value in squashfs_get_parent" bug.
This is caused by open_by_handle_at() being called with a file handle
containing an invalid parent inode number. In particular the inode number
is that of a symbolic link, rather than a directory.
Squashfs_get_parent() gets called with that symbolic link inode, and
accesses the parent member field.
unsigned int parent_ino = squashfs_i(inode)->parent;
Because non-directory inodes in Squashfs do not have a parent value, this
is uninitialised, and this causes an uninitialised value access.
The fix is to initialise parent with the invalid inode 0, which will cause
an EINVAL error to be returned.
Regular inodes used to share the parent field with the block_list_start
field. This is removed in this commit to enable the parent field to
contain the invalid inode number 0.

This bug is caused by the fact that usbnet trusts the bulk endpoint
addresses its probe routine receives in the driver_info structure, and
it does not check to see that these endpoints actually exist and have
the expected type and directions.
The fix is simply to add such a check.

Summary
In the Linux kernel, the following vulnerability has been resolved:
writeback: avoid use-after-free after removing device
When a disk is removed, bdi_unregister gets called to stop further
writeback and wait for associated delayed work to complete. However,
wb_inode_writeback_end() may schedule bandwidth estimation dwork after
this has completed, which can result in the timer attempting to access the
just freed bdi_writeback.
Fix this by checking if the bdi_writeback is alive, similar to when
scheduling writeback work.
Since this requires wb->work_lock, and wb_inode_writeback_end() may get
called from interrupt, switch wb->work_lock to an irqsafe lock.

Root-only sysfs delete is not required for the worst reasonable removable-media scenario.\nUI:N - The attacker can complete the full sequence (dirty data then eject/remove the device they wrote to) without relying on a separate victim action.\nS:U - This is a host-kernel use-after-free leading to privilege escalation within the same OS security authority, not a VM escape or IOMMU/cross-boundary breakout.\nC:H - Use-after-free of the bdi_writeback object lets an attacker reclaim and control freed kernel memory, enabling arbitrary kernel read primitives.\nI:H - The same UAF is exploitable via heap spray for arbitrary kernel writes and control-flow hijacking through the delayed bandwidth-update work path.\nA:H - The freed bdi_writeback is accessed from delayed work (observed as a KASAN splat), which can oops/panic the kernel even when not fully exploited."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ntfs: Fix panic about slab-out-of-bounds caused by ntfs_listxattr()
Here is a BUG report from syzbot:

Reproduction script:
mkdir -p /mnt/nfsshare
mkdir -p /mnt/nfs/netns_1
mkfs.ext4 /dev/sdb
mount /dev/sdb /mnt/nfsshare
systemctl restart nfs-server
chmod 777 /mnt/nfsshare
exportfs -i -o rw,no_root_squash *:/mnt/nfsshare
ip netns add netns_1
ip link add name veth_1_peer type veth peer veth_1
ifconfig veth_1_peer 11.11.0.254 up
ip link set veth_1 netns netns_1
ip netns exec netns_1 ifconfig veth_1 11.11.0.1
ip netns exec netns_1 /root/iptables -A OUTPUT -d 11.11.0.254 -p tcp \
--tcp-flags FIN FIN -j DROP
(note: In my environment, a DESTROY_CLIENTID operation is always sent
immediately, breaking the nfs tcp connection.)
ip netns exec netns_1 timeout -s 9 300 mount -t nfs -o proto=tcp,vers=4.1 \
11.11.0.254:/mnt/nfsshare /mnt/nfs/netns_1
ip netns del netns_1
The reason here is that the tcp socket in netns_1 (nfs side) has been
shutdown and closed (done in xs_destroy), but the FIN message (with ack)
is discarded, and the nfsd side keeps sending retransmission messages.
As a result, when the tcp sock in netns_1 processes the received message,
it sends the message (FIN message) in the sending queue, and the tcp timer
is re-established. When the network namespace is deleted, the net structure
accessed by tcp's timer handler function causes problems.
To fix this problem, let's hold netns refcnt for the tcp kernel socket as
done in other modules. This is an ugly hack which can easily be backported
to earlier kernels. A proper fix which cleans up the interfaces will
follow, but may not be so easy to backport.

When the network namespace is deleted, the net structure\naccessed by tcp\u0027s timer handler function causes problems.\n\nTo fix this problem, let\u0027s hold netns refcnt for the tcp kernel socket as\ndone in other modules. This is an ugly hack which can easily be backported\nto earlier kernels. A proper fix which cleans up the interfaces will\nfollow, but may not be so easy to backport."

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix space cache corruption and potential double allocations
When testing space_cache v2 on a large set of machines, we encountered a
few symptoms:
1. "unable to add free space :-17" (EEXIST) errors.
2. Missing free space info items, sometimes caught with a "missing free
space info for X" error.
3. Double-accounted space: ranges that were allocated in the extent tree
and also marked as free in the free space tree, ranges that were
marked as allocated twice in the extent tree, or ranges that were
marked as free twice in the free space tree. If the latter made it
onto disk, the next reboot would hit the BUG_ON() in
add_new_free_space().
4. On some hosts with no on-disk corruption or error messages, the
in-memory space cache (dumped with drgn) disagreed with the free
space tree.
All of these symptoms have the same underlying cause: a race between
caching the free space for a block group and returning free space to the
in-memory space cache for pinned extents causes us to double-add a free
range to the space cache. This race exists when free space is cached
from the free space tree (space_cache=v2) or the extent tree
(nospace_cache, or space_cache=v1 if the cache needs to be regenerated).
struct btrfs_block_group::last_byte_to_unpin and struct
btrfs_block_group::progress are supposed to protect against this race,
but commit d0c2f4fa555e ("btrfs: make concurrent fsyncs wait less when
waiting for a transaction commit") subtly broke this by allowing
multiple transactions to be unpinning extents at the same time.
Specifically, the race is as follows:
1. An extent is deleted from an uncached block group in transaction A.
2. btrfs_commit_transaction() is called for transaction A.
3. btrfs_run_delayed_refs() -> __btrfs_free_extent() runs the delayed
ref for the deleted extent.
4. __btrfs_free_extent() -> do_free_extent_accounting() ->
add_to_free_space_tree() adds the deleted extent back to the free
space tree.
5. do_free_extent_accounting() -> btrfs_update_block_group() ->
btrfs_cache_block_group() queues up the block group to get cached.
block_group->progress is set to block_group->start.
6. btrfs_commit_transaction() for transaction A calls
switch_commit_roots(). It sets block_group->last_byte_to_unpin to
block_group->progress, which is block_group->start because the block
group hasn't been cached yet.
7. The caching thread gets to our block group. Since the commit roots
were already switched, load_free_space_tree() sees the deleted extent
as free and adds it to the space cache. It finishes caching and sets
block_group->progress to U64_MAX.
8. btrfs_commit_transaction() advances transaction A to
TRANS_STATE_SUPER_COMMITTED.
9. fsync calls btrfs_commit_transaction() for transaction B. Since
transaction A is already in TRANS_STATE_SUPER_COMMITTED and the
commit is for fsync, it advances.
10. btrfs_commit_transaction() for transaction B calls
switch_commit_roots(). This time, the block group has already been
cached, so it sets block_group->last_byte_to_unpin to U64_MAX.
11. btrfs_commit_transaction() for transaction A calls
btrfs_finish_extent_commit(), which calls unpin_extent_range() for
the deleted extent. It sees last_byte_to_unpin set to U64_MAX (by
transaction B!), so it adds the deleted extent to the space cache
again!
This explains all of our symptoms above:
* If the sequence of events is exactly as described above, when the free
space is re-added in step 11, it will fail with EEXIST.
* If another thread reallocates the deleted extent in between steps 7
and 11, then step 11 will silently re-add that space to the space
cache as free even though it is actually allocated. Then, if that
space is allocated *again*, the free space tree will be corrupted
(namely, the wrong item will be deleted).
* If we don't catch this free space tree corr

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfc: nxp-nci: Fix potential memory leak in nxp_nci_send()
nxp_nci_send() will call nxp_nci_i2c_write(), and only free skb when
nxp_nci_i2c_write() failed. However, even if the nxp_nci_i2c_write()
run succeeds, the skb will not be freed in nxp_nci_i2c_write(). As the
result, the skb will memleak. nxp_nci_send() should also free the skb
when nxp_nci_i2c_write() succeeds.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Avoid order-5 memory allocation for TPA data
The driver needs to keep track of all the possible concurrent TPA (GRO/LRO)
completions on the aggregation ring. On P5 chips, the maximum number
of concurrent TPA is 256 and the amount of memory we allocate is order-5
on systems using 4K pages. Memory allocation failure has been reported:
NetworkManager: page allocation failure: order:5, mode:0x40dc0(GFP_KERNEL|__GFP_COMP|__GFP_ZERO), nodemask=(null),cpuset=/,mems_allowed=0-1
CPU: 15 PID: 2995 Comm: NetworkManager Kdump: loaded Not tainted 5.10.156 #1
Hardware name: Dell Inc. PowerEdge R660/0M1CC5, BIOS 0.2.25 08/12/2022

Instead of allocating this big chunk of memory and dividing it up for the
concurrent TPA instances, allocate each small chunk separately for each
TPA instance. This will reduce it to order-0 allocations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix deadlock in nilfs_count_free_blocks()
A semaphore deadlock can occur if nilfs_get_block() detects metadata
corruption while locating data blocks and a superblock writeback occurs at
the same time:
task 1 task 2
------ ------
* A file operation *
nilfs_truncate()
nilfs_get_block()
down_read(rwsem A) <--
nilfs_bmap_lookup_contig()
... generic_shutdown_super()
nilfs_put_super()
* Prepare to write superblock *
down_write(rwsem B) <--
nilfs_cleanup_super()
* Detect b-tree corruption * nilfs_set_log_cursor()
nilfs_bmap_convert_error() nilfs_count_free_blocks()
__nilfs_error() down_read(rwsem A) <--
nilfs_set_error()
down_write(rwsem B) <--
*** DEADLOCK ***
Here, nilfs_get_block() readlocks rwsem A (= NILFS_MDT(dat_inode)->mi_sem)
and then calls nilfs_bmap_lookup_contig(), but if it fails due to metadata
corruption, __nilfs_error() is called from nilfs_bmap_convert_error()
inside the lock section.
Since __nilfs_error() calls nilfs_set_error() unless the filesystem is
read-only and nilfs_set_error() attempts to writelock rwsem B (=
nilfs->ns_sem) to write back superblock exclusively, hierarchical lock
acquisition occurs in the order rwsem A -> rwsem B.
Now, if another task starts updating the superblock, it may writelock
rwsem B during the lock sequence above, and can deadlock trying to
readlock rwsem A in nilfs_count_free_blocks().
However, there is actually no need to take rwsem A in
nilfs_count_free_blocks() because it, within the lock section, only reads
a single integer data on a shared struct with
nilfs_sufile_get_ncleansegs(). This has been the case after commit
aa474a220180 ("nilfs2: add local variable to cache the number of clean
segments"), that is, even before this bug was introduced.
So, this resolves the deadlock problem by just not taking the semaphore in
nilfs_count_free_blocks().

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Fix cleanup null-ptr deref on encap lock
During module is unloaded while a peer tc flow is still offloaded,
first the peer uplink rep profile is changed to a nic profile, and so
neigh encap lock is destroyed. Next during unload, the VF reps netdevs
are unregistered which causes the original non-peer tc flow to be deleted,
which deletes the peer flow. The peer flow deletion detaches the encap
entry and try to take the already destroyed encap lock, causing the
below trace.
Fix this by clearing peer flows during tc eswitch cleanup
(mlx5e_tc_esw_cleanup()).

which is supposed to be safe with how requests are allocated. But msg
ring requests alloc and free on their own, and hence must defer freeing
to a sane time.
Add an rcu_head and use kfree_rcu() in both spots where requests are
freed. Only the one in io_msg_tw_complete() is strictly required as it
has been visible on the other ring, but use it consistently in the other
spot as well.
This should not cause any other issues outside of KASAN rightfully
complaining about it.

Per kernel scoring guidance io_uring bugs are Local.\nAC:L - The attacker creates and fully controls both sides of the race \u2014 the target ring (with `IORING_SETUP_DEFER_TASKRUN|SINGLE_ISSUER`), the flood of MSG_RING requests from io-wq workers on one CPU, and the reaping task that frees those requests on another \u2014 so it can be hit repeatedly at will, as syzbot\u0027s reproducer demonstrates. No precondition lies outside the attacker\u0027s influence; the required ring flags are runtime choices, not a rare build config.\nPR:L - Any unprivileged local user can create io_uring instances and submit `IORING_OP_MSG_RING`; there is no capability, credential, or LSM gate anywhere along `io_msg_ring() \u2192 io_msg_data_remote() \u2192 io_req_local_work_add()`, and `kernel.io_uring_disabled` is 0 by default. The path is equally reachable from inside an unprivileged container or user namespace.\nUI:N - Exploitation is entirely self-driven by the attacker\u0027s own two threads submitting and reaping io_uring requests. No victim action, mount, or file access is involved.\nS:U - The freed `io_kiocb` and the code dereferencing it both live in the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed. Standard kernel-local impact.\nC:H - A freed `io_kiocb` from the shared `req_cachep` slab is dereferenced after `kmem_cache_free()`, and an attacker who grooms slab reuse controls what object occupies that memory when it is read. Consistent with treating use-after-free as enabling attacker-influenced disclosure of kernel memory contents, this is High.\nI:H - The stale read feeds the `nr_tw` value written into the newly queued request and drives the task-wakeup decision, so freed/reallocated memory directly influences kernel control state. Use-after-free conditions on a heap-spray-friendly cache such as `io_kiocb` are treated as High integrity impact.\nA:H - This is a confirmed KASAN slab-use-after-free that panics kernels built with KASAN or `panic_on_warn`, and on production kernels a garbage `nr_tw_prev` can exceed `cq_wait_nr` and suppress the `wake_up_state()` of the target ring\u0027s submitter, stalling a task that is waiting on already-queued work. Both outcomes are triggerable repeatedly by an unprivileged user."

Summary
In the Linux kernel, the following vulnerability has been resolved:
vt: Clear selection before changing the font
When changing the console font with ioctl(KDFONTOP) the new font size
can be bigger than the previous font. A previous selection may thus now
be outside of the new screen size and thus trigger out-of-bounds
accesses to graphics memory if the selection is removed in
vc_do_resize().
Prevent such out-of-memory accesses by dropping the selection before the
various con_font_set() console handlers are called.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iavf: Fix reset error handling
Do not call iavf_close in iavf_reset_task error handling. Doing so can
lead to double call of napi_disable, which can lead to deadlock there.
Removing VF would lead to iavf_remove task being stuck, because it
requires crit_lock, which is held by iavf_close.
Call iavf_disable_vf if reset fail, so that driver will clean up
remaining invalid resources.
During rapid VF resets, HW can fail to setup VF mailbox. Wrong
error handling can lead to iavf_remove being stuck with:

Summary
In the Linux kernel, the following vulnerability has been resolved:
apparmor: Fix memleak in aa_simple_write_to_buffer()
When copy_from_user failed, the memory is freed by kvfree. however the
management struct and data blob are allocated independently, so only
kvfree(data) cause a memleak issue here. Use aa_put_loaddata(data) to
fix this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: hyperv: avoid struct memcpy overrun warning
A previous patch addressed the fortified memcpy warning for most
builds, but I still see this one with gcc-9:
In file included from include/linux/string.h:254,
from drivers/hid/hid-hyperv.c:8:
In function 'fortify_memcpy_chk',
inlined from 'mousevsc_on_receive' at drivers/hid/hid-hyperv.c:272:3:
include/linux/fortify-string.h:583:4: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning]
583 | __write_overflow_field(p_size_field, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
My guess is that the WARN_ON() itself is what confuses gcc, so it no
longer sees that there is a correct range check. Rework the code in a
way that helps readability and avoids the warning.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: Don't tx before switchdev is fully configured
There is possibility that ice_eswitch_port_start_xmit might be
called while some resources are still not allocated which might
cause NULL pointer dereference. Fix this by checking if switchdev
configuration was finished.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: imu: bno055: fix OOB access of hw_xlate array
Fix a potential out-of-bounds array access of the hw_xlate array in
bno055.c.
In bno055_get_regmask(), hw_xlate was iterated over the length of the
vals array instead of the length of the hw_xlate array. In the case of
bno055_gyr_scale, the vals array is larger than the hw_xlate array,
so this could result in an out-of-bounds access. In practice, this
shouldn't happen though because a match should always be found which
breaks out of the for loop before it iterates beyond the end of the
hw_xlate array.
By adding a new hw_xlate_len field to the bno055_sysfs_attr, we can be
sure we are iterating over the correct length.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: af_alg - Fix missing initialisation affecting gcm-aes-s390
Fix af_alg_alloc_areq() to initialise areq->first_rsgl.sgl.sgt.sgl to point
to the scatterlist array in areq->first_rsgl.sgl.sgl.
Without this, the gcm-aes-s390 driver will oops when it tries to do
gcm_walk_start() on req->dst because req->dst is set to the value of
areq->first_rsgl.sgl.sgl by _aead_recvmsg() calling
aead_request_set_crypt().
The problem comes if an empty ciphertext is passed: the loop in
af_alg_get_rsgl() just passes straight out and doesn't set areq->first_rsgl
up.
This isn't a problem on x86_64 using gcmaes_crypt_by_sg() because, as far
as I can tell, that ignores req->dst and only uses req->src[*].
[*] Is this a bug in aesni-intel_glue.c?
The s390x oops looks something like:
Unable to handle kernel pointer dereference in virtual kernel address space
Failing address: 0000000a00000000 TEID: 0000000a00000803
Fault in home space mode while using kernel ASCE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: ipq8074: dont disable gcc_sleep_clk_src
Once the usb sleep clocks are disabled, clock framework is trying to
disable the sleep clock source also.
However, it seems that it cannot be disabled and trying to do so produces:
[ 245.436390] ------------[ cut here ]------------

So, add CLK_IS_CRITICAL flag to the clock so that the kernel won't try
to disable the sleep clock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/fpu: Drop fpregs lock before inheriting FPU permissions
Mike Galbraith reported the following against an old fork of preempt-rt
but the same issue also applies to the current preempt-rt tree.
BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:46
in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 1, name: systemd
preempt_count: 1, expected: 0
RCU nest depth: 0, expected: 0
Preemption disabled at:
fpu_clone
CPU: 6 PID: 1 Comm: systemd Tainted: G E (unreleased)
Call Trace:

Mike says:
The splat comes from fpu_inherit_perms() being called under fpregs_lock(),
and us reaching the spin_lock_irq() therein due to fpu_state_size_dynamic()
returning true despite static key __fpu_state_size_dynamic having never
been enabled.
Mike's assessment looks correct. fpregs_lock on a PREEMPT_RT kernel disables
preemption so calling spin_lock_irq() in fpu_inherit_perms() is unsafe. This
problem exists since commit
9e798e9aa14c ("x86/fpu: Prepare fpu_clone() for dynamically enabled features").
Even though the original bug report should not have enabled the paths at
all, the bug still exists.
fpregs_lock is necessary when editing the FPU registers or a task's FP
state but it is not necessary for fpu_inherit_perms(). The only write
of any FP state in fpu_inherit_perms() is for the new child which is
not running yet and cannot context switch or be borrowed by a kernel
thread yet. Hence, fpregs_lock is not protecting anything in the new
child until clone() completes and can be dropped earlier. The siglock
still needs to be acquired by fpu_inherit_perms() as the read of the
parent's permissions has to be serialised.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vfio: Split migration ops from main device ops
vfio core checks whether the driver sets some migration op (e.g.
set_state/get_state) and accordingly calls its op.
However, currently mlx5 driver sets the above ops without regards to its
migration caps.
This might lead to unexpected usage/Oops if user space may call to the
above ops even if the driver doesn't support migration. As for example,
the migration state_mutex is not initialized in that case.
The cleanest way to manage that seems to split the migration ops from
the main device ops, this will let the driver setting them separately
from the main ops when it's applicable.
As part of that, validate ops construction on registration and include a
check for VFIO_MIGRATION_STOP_COPY since the uAPI claims it must be set
in migration_flags.
HISI driver was changed as well to match this scheme.
This scheme may enable down the road to come with some extra group of
ops (e.g. DMA log) that can be set without regards to the other options
based on driver caps.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Fix race condition in hci_cmd_sync_clear
There is a potential race condition in hci_cmd_sync_work and
hci_cmd_sync_clear, and could lead to use-after-free. For instance,
hci_cmd_sync_work is added to the 'req_workqueue' after cancel_work_sync
The entry of 'cmd_sync_work_list' may be freed in hci_cmd_sync_clear, and
causing kernel panic when it is used in 'hci_cmd_sync_work'.

net: ip_tunnel: prevent perpetual headroom growth

...
The splat occurs because skb->data points past skb->head allocated area.
This is because neigh layer does:
__skb_pull(skb, skb_network_offset(skb));
... but skb_network_offset() returns a negative offset and __skb_pull()
arg is unsigned. IOW, we skb->data gets "adjusted" by a huge value.
The negative value is returned because skb->head and skb->data distance is
more than 64k and skb->network_header (u16) has wrapped around.
The bug is in the ip_tunnel infrastructure, which can cause
dev->needed_headroom to increment ad infinitum.
The syzkaller reproducer consists of packets getting routed via a gre
tunnel, and route of gre encapsulated packets pointing at another (ipip)
tunnel. The ipip encapsulation finds gre0 as next output device.
This results in the following pattern:
1). First packet is to be sent out via gre0.
Route lookup found an output device, ipip0.
2).
ip_tunnel_xmit for gre0 bumps gre0->needed_headroom based on the future
output device, rt.dev->needed_headroom (ipip0).
3).
ip output / start_xmit moves skb on to ipip0. which runs the same
code path again (xmit recursion).
4).
Routing step for the post-gre0-encap packet finds gre0 as output device
to use for ipip0 encapsulated packet.
tunl0->needed_headroom is then incremented based on the (already bumped)
gre0 device headroom.
This repeats for every future packet:
gre0->needed_headroom gets inflated because previous packets' ipip0 step
incremented rt->dev (gre0) headroom, and ipip0 incremented because gre0
needed_headroom was increased.
For each subsequent packet, gre/ipip0->needed_headroom grows until
post-expand-head reallocations result in a skb->head/data distance of
more than 64k.
Once that happens, skb->network_header (u16) wraps around when
pskb_expand_head tries to make sure that skb_network_offset() is unchanged
after the headroom expansion/reallocation.
After this skb_network_offset(skb) returns a different (and negative)
result post headroom expansion.
The next trip to neigh layer (or anything else that would __skb_pull the
network header) makes skb->data point to a memory location outside
skb->head area.
v2: Cap the needed_headroom update to an arbitarily chosen upperlimit to
prevent perpetual increase instead of dropping the headroom increment
completely.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: avoid invalid memory access via node_online(NUMA_NO_NODE)
KASAN reports:
[ 4.668325][ T0] BUG: KASAN: wild-memory-access in dmar_parse_one_rhsa (arch/x86/include/asm/bitops.h:214 arch/x86/include/asm/bitops.h:226 include/asm-generic/bitops/instrumented-non-atomic.h:142 include/linux/nodemask.h:415 drivers/iommu/intel/dmar.c:497)
[ 4.676149][ T0] Read of size 8 at addr 1fffffff85115558 by task swapper/0/0
[ 4.683454][ T0]
[ 4.685638][ T0] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 5.19.0-rc3-00004-g0e862838f290 #1
[ 4.694331][ T0] Hardware name: Supermicro SYS-5018D-FN4T/X10SDV-8C-TLN4F, BIOS 1.1 03/02/2016
[ 4.703196][ T0] Call Trace:
[ 4.706334][ T0] <TASK>
[ 4.709133][ T0] ? dmar_parse_one_rhsa (arch/x86/include/asm/bitops.h:214 arch/x86/include/asm/bitops.h:226 include/asm-generic/bitops/instrumented-non-atomic.h:142 include/linux/nodemask.h:415 drivers/iommu/intel/dmar.c:497)
after converting the type of the first argument (@nr, bit number)
of arch_test_bit() from `long` to `unsigned long`[0].
Under certain conditions (for example, when ACPI NUMA is disabled
via command line), pxm_to_node() can return %NUMA_NO_NODE (-1).
It is valid 'magic' number of NUMA node, but not valid bit number
to use in bitops.
node_online() eventually descends to test_bit() without checking
for the input, assuming it's on caller side (which might be good
for perf-critical tasks). There, -1 becomes %ULONG_MAX which leads
to an insane array index when calculating bit position in memory.
For now, add an explicit check for @node being not %NUMA_NO_NODE
before calling test_bit(). The actual logics didn't change here
at all.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: mediatek-gen3: Fix refcount leak in mtk_pcie_init_irq_domains()
of_get_child_by_name() returns a node pointer with refcount incremented, so
we should use of_node_put() on it when we don't need it anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: use RCU for hci_conn_params and iterate safely in hci_sync
hci_update_accept_list_sync iterates over hdev->pend_le_conns and
hdev->pend_le_reports, and waits for controller events in the loop body,
without holding hdev lock.
Meanwhile, these lists and the items may be modified e.g. by
le_scan_cleanup. This can invalidate the list cursor or any other item
in the list, resulting to invalid behavior (eg use-after-free).
Use RCU for the hci_conn_params action lists. Since the loop bodies in
hci_sync block and we cannot use RCU or hdev->lock for the whole loop,
copy list items first and then iterate on the copy. Only the flags field
is written from elsewhere, so READ_ONCE/WRITE_ONCE should guarantee we
read valid values.
Free params everywhere with hci_conn_params_free so the cleanup is
guaranteed to be done properly.
This fixes the following, which can be triggered e.g. by BlueZ new
mgmt-tester case "Add + Remove Device Nowait - Success", or by changing
hci_le_set_cig_params to always return false, and running iso-tester:

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/MCE: Always save CS register on AMD Zen IF Poison errors
The Instruction Fetch (IF) units on current AMD Zen-based systems do not
guarantee a synchronous #MC is delivered for poison consumption errors.
Therefore, MCG_STATUS[EIPV|RIPV] will not be set. However, the
microarchitecture does guarantee that the exception is delivered within
the same context. In other words, the exact rIP is not known, but the
context is known to not have changed.
There is no architecturally-defined method to determine this behavior.
The Code Segment (CS) register is always valid on such IF unit poison
errors regardless of the value of MCG_STATUS[EIPV|RIPV].
Add a quirk to save the CS register for poison consumption from the IF
unit banks.
This is needed to properly determine the context of the error.
Otherwise, the severity grading function will assume the context is
IN_KERNEL due to the m->cs value being 0 (the initialized value). This
leads to unnecessary kernel panics on data poison errors due to the
kernel believing the poison consumption occurred in kernel context.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sch_htb: make htb_deactivate() idempotent
Alan reported a NULL pointer dereference in htb_next_rb_node()
after we made htb_qlen_notify() idempotent.
It turns out in the following case it introduced some regression:
htb_dequeue_tree():
|-> fq_codel_dequeue()
|-> qdisc_tree_reduce_backlog()
|-> htb_qlen_notify()
|-> htb_deactivate()
|-> htb_next_rb_node()
|-> htb_deactivate()
For htb_next_rb_node(), after calling the 1st htb_deactivate(), the
clprio[prio]->ptr could be already set to NULL, which means
htb_next_rb_node() is vulnerable here.
For htb_deactivate(), although we checked qlen before calling it, in
case of qlen==0 after qdisc_tree_reduce_backlog(), we may call it again
which triggers the warning inside.
To fix the issues here, we need to:
1) Make htb_deactivate() idempotent, that is, simply return if we
already call it before.
2) Make htb_next_rb_node() safe against ptr==NULL.
Many thanks to Alan for testing and for the reproducer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: gadget: Fix obscure lockdep violation for udc_mutex
A recent commit expanding the scope of the udc_lock mutex in the
gadget core managed to cause an obscure and slightly bizarre lockdep
violation. In abbreviated form:
======================================================

Evidently this was caused by the scope of udc_mutex being too large.
The mutex is only meant to protect udc->driver along with a few other
things. As far as I can tell, there's no reason for the mutex to be
held while the gadget core calls a gadget driver's ->bind or ->unbind
routine, or while a UDC is being started or stopped. (This accounts
for link #1 in the chain above, where the mutex is held while the
dwc2_hsotg_udc is started as part of driver probing.)
Gadget drivers' ->disconnect callbacks are problematic. Even though
usb_gadget_disconnect() will now acquire the udc_mutex, there's a
window in usb_gadget_bind_driver() between the times when the mutex is
released and the ->bind callback is invoked. If a disconnect occurred
during that window, we could call the driver's ->disconnect routine
before its ->bind routine. To prevent this from happening, it will be
necessary to prevent a UDC from connecting while it has no gadget
driver. This should be done already but it doesn't seem to be;
currently usb_gadget_connect() has no check for this. Such a check
will have to be added later.
Some degree of mutual exclusion is required in soft_connect_store(),
which can dereference udc->driver at arbitrary times since it is a
sysfs callback. The solution here is to acquire the gadget's device
lock rather than the udc_mutex. Since the driver core guarantees that
the device lock is always held during driver binding and unbinding,
this will make the accesses in soft_connect_store() mutually exclusive
with any changes to udc->driver.
Lastly, it turns out there is one place which should hold the
udc_mutex but currently does not: The function_show() routine needs
protection while it dereferences udc->driver. The missing lock and
unlock calls are added.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock: Keep the binding until socket destruction
Preserve sockets bindings; this includes both resulting from an explicit
bind() and those implicitly bound through autobind during connect().
Prevents socket unbinding during a transport reassignment, which fixes a
use-after-free:
1. vsock_create() (refcnt=1) calls vsock_insert_unbound() (refcnt=2)
2. transport->release() calls vsock_remove_bound() without checking if
sk was bound and moved to bound list (refcnt=1)
3. vsock_bind() assumes sk is in unbound list and before
__vsock_insert_bound(vsock_bound_sockets()) calls
__vsock_remove_bound() which does:
list_del_init(&vsk->bound_table); // nop
sock_put(&vsk->sk); // refcnt=0

Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio-mmio: don't break lifecycle of vm_dev
vm_dev has a separate lifecycle because it has a 'struct device'
embedded. Thus, having a release callback for it is correct.
Allocating the vm_dev struct with devres totally breaks this protection,
though. Instead of waiting for the vm_dev release callback, the memory
is freed when the platform_device is removed. Resulting in a
use-after-free when finally the callback is to be called.
To easily see the problem, compile the kernel with
CONFIG_DEBUG_KOBJECT_RELEASE and unbind with sysfs.
The fix is easy, don't use devres in this case.
Found during my research about object lifetime problems.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/x25: Fix skb leak in x25_lapb_receive_frame()
x25_lapb_receive_frame() using skb_copy() to get a private copy of
skb, the new skb should be freed in the undersized/fragmented skb
error handling path. Otherwise there is a memory leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
null_blk: fix poll request timeout handling
When doing io_uring benchmark on /dev/nullb0, it's easy to crash the
kernel if poll requests timeout triggered, as reported by David. [1]
BUG: kernel NULL pointer dereference, address: 0000000000000008
Workqueue: kblockd blk_mq_timeout_work
RIP: 0010:null_timeout_rq+0x4e/0x91
Call Trace:
? null_timeout_rq+0x4e/0x91
blk_mq_handle_expired+0x31/0x4b
bt_iter+0x68/0x84
? bt_tags_iter+0x81/0x81

blk_mq_timeout_work+0x95/0x127
process_one_work+0x185/0x263
worker_thread+0x1b5/0x227
This is indeed a race problem between null_timeout_rq() and null_poll().
null_poll() null_timeout_rq()
spin_lock(&nq->poll_lock)
list_splice_init(&nq->poll_list, &list)
spin_unlock(&nq->poll_lock)
while (!list_empty(&list))
req = list_first_entry()
list_del_init()
...
blk_mq_add_to_batch()
// req->rq_next = NULL
spin_lock(&nq->poll_lock)
// rq->queuelist->next == NULL
list_del_init(&rq->queuelist)
spin_unlock(&nq->poll_lock)
Fix these problems by setting requests state to MQ_RQ_COMPLETE under
nq->poll_lock protection, in which null_timeout_rq() can safely detect
this race and early return.
Note this patch just fix the kernel panic when request timeout happen.

Summary
In the Linux kernel, the following vulnerability has been resolved:
meson-mx-socinfo: Fix refcount leak in meson_mx_socinfo_init
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: steam: Prevent NULL pointer dereference in steam_{recv,send}_report
It is possible for a malicious device to forgo submitting a Feature
Report. The HID Steam driver presently makes no prevision for this
and de-references the 'struct hid_report' pointer obtained from the
HID devices without first checking its validity. Let's change that.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: conntrack: dccp: copy entire header to stack buffer, not just basic one
Eric Dumazet says:
nf_conntrack_dccp_packet() has an unique:
dh = skb_header_pointer(skb, dataoff, sizeof(_dh), &_dh);
And nothing more is 'pulled' from the packet, depending on the content.
dh->dccph_doff, and/or dh->dccph_x ...)
So dccp_ack_seq() is happily reading stuff past the _dh buffer.
BUG: KASAN: stack-out-of-bounds in nf_conntrack_dccp_packet+0x1134/0x11c0
Read of size 4 at addr ffff000128f66e0c by task syz-executor.2/29371
[..]
Fix this by increasing the stack buffer to also include room for
the extra sequence numbers and all the known dccp packet type headers,
then pull again after the initial validation of the basic header.
While at it, mark packets invalid that lack 48bit sequence bit but
where RFC says the type MUST use them.
Compile tested only.
v2: first skb_header_pointer() now needs to adjust the size to
only pull the generic header. (Eric)
Heads-up: I intend to remove dccp conntrack support later this year.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix sleeping-in-atomic in ath11k_mac_op_set_bitrate_mask()
ath11k_mac_disable_peer_fixed_rate() is passed as the iterator to
ieee80211_iterate_stations_atomic(). Note in this case the iterator is
required to be atomic, however ath11k_mac_disable_peer_fixed_rate() does
not follow it as it might sleep. Consequently below warning is seen:
BUG: sleeping function called from invalid context at wmi.c:304
Call Trace:
<TASK>

ieee80211_iterate_stations_atomic
ath11k_mac_op_set_bitrate_mask.cold
Change to ieee80211_iterate_stations_mtx() to fix this issue.

Extending it to an actual block (and thus a grace-period-completing context switch) only requires having peers associated and saturating WMI credits, both of which the attacker can arrange.\nPR:L - Both entry points gate on CAP_NET_ADMIN (GENL_UNS_ADMIN_PERM for nl80211, capable(CAP_NET_ADMIN) for WEXT), which is a namespace-aware network-administration capability rather than real root, and is routinely delegated to unprivileged-facing daemons (wpa_supplicant, NetworkManager helpers, hostapd) on phones, APs and embedded gateways.\nUI:N - The attacker performs the bitrate-mask configuration itself; no second user has to open a file, mount media, or take any action for the bug to fire.\nS:U - The fault, the corrupted RCU-protected station list, and the resulting crash all stay within the same kernel security authority on the host; no VM, IOMMU, container, or sandbox boundary is crossed.\nC:H - Blocking for up to WMI_SEND_TIMEOUT_HZ inside the rcu_read_lock() of __iterate_stations() lets the grace period complete on non-preemptible-RCU builds, so a concurrently destroyed sta_info can be freed and reallocated while the iterator is parked on it; the resumed list_for_each_entry_rcu() then reads freed/attacker-groomed heap through sta-\u003eaddr and the list pointers, leaking that content into the WMI peer command and the ath11k_warn(\"...for STA %pM\") log line.\nI:H - The same use-after-free lets the traversal follow a dangling next pointer into reclaimed, attacker-sprayable memory and feed the resulting garbage into firmware peer-parameter commands, and __schedule_bug() additionally resets the preempt count, leaving the scheduler\u0027s atomic-nesting state inconsistent for the remainder of the task.\nA:H - The bug reliably produces a \"BUG: sleeping function called from invalid context\" splat plus a scheduling-while-atomic BUG with full call trace, which escalates to a full panic on panic_on_warn/panic_on_oops kernels common in embedded and cloud images, and the RCU-list use-after-free can oops the kernel outright."

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: sme: Use STR P to clear FFR context field in streaming SVE mode
The FFR is a predicate register which can vary between 16 and 256 bits
in size depending upon the configured vector length. When saving the
SVE state in streaming SVE mode, the FFR register is inaccessible and
so commit 9f5848665788 ("arm64/sve: Make access to FFR optional") simply
clears the FFR field of the in-memory context structure. Unfortunately,
it achieves this using an unconditional 8-byte store and so if the SME
vector length is anything other than 64 bytes in size we will either
fail to clear the entire field or, worse, we will corrupt memory
immediately following the structure. This has led to intermittent kfence
splats in CI [1] and can trigger kmalloc Redzone corruption messages
when running the 'fp-stress' kselftest:
| =============================================================================
| BUG kmalloc-1k (Not tainted): kmalloc Redzone overwritten
| -----------------------------------------------------------------------------
|
| 0xffff000809bf1e22-0xffff000809bf1e27 @offset=7714. First byte 0x0 instead of 0xcc
| Allocated in do_sme_acc+0x9c/0x220 age=2613 cpu=1 pid=531
| __kmalloc+0x8c/0xcc
| do_sme_acc+0x9c/0x220
| ...
Replace the 8-byte store with a store of a predicate register which has
been zero-initialised with PFALSE, ensuring that the entire field is
cleared in memory.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: make sure exp active before svc_export_show
The function `e_show` was called with protection from RCU. This only
ensures that `exp` will not be freed. Therefore, the reference count for
`exp` can drop to zero, which will trigger a refcount use-after-free
warning when `exp_get` is called. To resolve this issue, use
`cache_get_rcu` to ensure that `exp` remains active.
------------[ cut here ]------------

Summary
In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8712: fix use after free bugs
_Read/Write_MACREG callbacks are NULL so the read/write_macreg_hdl()
functions don't do anything except free the "pcmd" pointer. It
results in a use after free. Delete them.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: fix memory leak in query_regdb_file()
In the function query_regdb_file() the alpha2 parameter is duplicated
using kmemdup() and subsequently freed in regdb_fw_cb(). However,
request_firmware_nowait() can fail without calling regdb_fw_cb() and
thus leak memory.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: simplefb: Fix use after free in simplefb_detach_genpds()
The pm_domain cleanup can not be devres managed as it uses struct
simplefb_par which is allocated within struct fb_info by
framebuffer_alloc(). This allocation is explicitly freed by
unregister_framebuffer() in simplefb_remove().
Devres managed cleanup runs after the device remove call and thus can no
longer access struct simplefb_par.
Call simplefb_detach_genpds() explicitly from simplefb_destroy() like
the cleanup functions for clocks and regulators.
Fixes an use after free on M2 Mac mini during
aperture_remove_conflicting_devices() using the downstream asahi kernel
with Debian's kernel config. For unknown reasons this started to
consistently dereference an invalid pointer in v6.16.3 based kernels.

Summary
In the Linux kernel, the following vulnerability has been resolved:
memcontrol: ensure memcg acquired by id is properly set up
In the eviction recency check, we attempt to retrieve the memcg to which
the folio belonged when it was evicted, by the memcg id stored in the
shadow entry. However, there is a chance that the retrieved memcg is not
the original memcg that has been killed, but a new one which happens to
have the same id.
This is a somewhat unfortunate, but acceptable and rare inaccuracy in the
heuristics. However, if we retrieve this new memcg between its allocation
and when it is properly attached to the memcg hierarchy, we could run into
the following NULL pointer exception during the memcg hierarchy traversal
done in mem_cgroup_get_nr_swap_pages():

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: mcba_usb: populate ndo_change_mtu() to prevent buffer overflow
Sending an PF_PACKET allows to bypass the CAN framework logic and to
directly reach the xmit() function of a CAN driver. The only check
which is performed by the PF_PACKET framework is to make sure that
skb->len fits the interface's MTU.
Unfortunately, because the mcba_usb driver does not populate its
net_device_ops->ndo_change_mtu(), it is possible for an attacker to
configure an invalid MTU by doing, for example:
$ ip link set can0 mtu 9999
After doing so, the attacker could open a PF_PACKET socket using the
ETH_P_CANXL protocol:
socket(PF_PACKET, SOCK_RAW, htons(ETH_P_CANXL))
to inject a malicious CAN XL frames. For example:
struct canxl_frame frame = {
.flags = 0xff,
.len = 2048,
};
The CAN drivers' xmit() function are calling can_dev_dropped_skb() to
check that the skb is valid, unfortunately under above conditions, the
malicious packet is able to go through can_dev_dropped_skb() checks:
1. the skb->protocol is set to ETH_P_CANXL which is valid (the
function does not check the actual device capabilities).
2. the length is a valid CAN XL length.
And so, mcba_usb_start_xmit() receives a CAN XL frame which it is not
able to correctly handle and will thus misinterpret it as a CAN frame.
This can result in a buffer overflow. The driver will consume cf->len
as-is with no further checks on these lines:
usb_msg.dlc = cf->len;
memcpy(usb_msg.data, cf->data, usb_msg.dlc);
Here, cf->len corresponds to the flags field of the CAN XL frame. In
our previous example, we set canxl_frame->flags to 0xff. Because the
maximum expected length is 8, a buffer overflow of 247 bytes occurs!
Populate net_device_ops->ndo_change_mtu() to ensure that the
interface's MTU can not be set to anything bigger than CAN_MTU. By
fixing the root cause, this prevents the buffer overflow.

The only check\nwhich is performed by the PF_PACKET framework is to make sure that\nskb-\u003elen fits the interface\u0027s MTU.\n\nUnfortunately, because the mcba_usb driver does not populate its\nnet_device_ops-\u003endo_change_mtu(), it is possible for an attacker to\nconfigure an invalid MTU by doing, for example:\n\n $ ip link set can0 mtu 9999\n\nAfter doing so, the attacker could open a PF_PACKET socket using the\nETH_P_CANXL protocol:\n\n\tsocket(PF_PACKET, SOCK_RAW, htons(ETH_P_CANXL))\n\nto inject a malicious CAN XL frames. For example:\n\n\tstruct canxl_frame frame = {\n\t\t.flags = 0xff,\n\t\t.len = 2048,\n\t};\n\nThe CAN drivers\u0027 xmit() function are calling can_dev_dropped_skb() to\ncheck that the skb is valid, unfortunately under above conditions, the\nmalicious packet is able to go through can_dev_dropped_skb() checks:\n\n 1. the skb-\u003eprotocol is set to ETH_P_CANXL which is valid (the\n function does not check the actual device capabilities).\n\n 2. the length is a valid CAN XL length.\n\nAnd so, mcba_usb_start_xmit() receives a CAN XL frame which it is not\nable to correctly handle and will thus misinterpret it as a CAN frame.\n\nThis can result in a buffer overflow. The driver will consume cf-\u003elen\nas-is with no further checks on these lines:\n\n\tusb_msg.dlc = cf-\u003elen;\n\n\tmemcpy(usb_msg.data, cf-\u003edata, usb_msg.dlc);\n\nHere, cf-\u003elen corresponds to the flags field of the CAN XL frame. In\nour previous example, we set canxl_frame-\u003eflags to 0xff. Because the\nmaximum expected length is 8, a buffer overflow of 247 bytes occurs!\n\nPopulate net_device_ops-\u003endo_change_mtu() to ensure that the\ninterface\u0027s MTU can not be set to anything bigger than CAN_MTU.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Fix memory corruption when FW resources change during ifdown
bnxt_set_dflt_rings() assumes that it is always called before any TC has
been created. So it doesn't take bp->num_tc into account and assumes
that it is always 0 or 1.
In the FW resource or capability change scenario, the FW will return
flags in bnxt_hwrm_if_change() that will cause the driver to
reinitialize and call bnxt_cancel_reservations(). This will lead to
bnxt_init_dflt_ring_mode() calling bnxt_set_dflt_rings() and bp->num_tc
may be greater than 1. This will cause bp->tx_ring[] to be sized too
small and cause memory corruption in bnxt_alloc_cp_rings().
Fix it by properly scaling the TX rings by bp->num_tc in the code
paths mentioned above. Add 2 helper functions to determine
bp->tx_nr_rings and bp->tx_nr_rings_per_tc.

states would poison env->cur_state.
Additionally, env->stack should not contain any states with
.loop_entry != NULL. The states in env->stack are yet to be verified,
while .loop_entry is set for states that reached an equivalent state.
This means that env->cur_state->loop_entry should always be NULL after
pop_stack().
See the selftest in the next commit for an example of the program that
is not safe yet is accepted by verifier w/o this fix.
This change has some verification performance impact for selftests:

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Add down_write(trace_event_sem) when adding trace event
When a module is loaded, it adds trace events defined by the module. It
may also need to modify the modules trace printk formats to replace enum
names with their values.
If two modules are loaded at the same time, the adding of the event to the
ftrace_events list can corrupt the walking of the list in the code that is
modifying the printk format strings and crash the kernel.
The addition of the event should take the trace_event_sem for write while
it adds the new event.
Also add a lockdep_assert_held() on that semaphore in
__trace_add_event_dirs() as it iterates the list.

No network or adjacent-network input reaches kernel/trace/trace_events.c.\nAC:L - The attacker controls both sides of the race, initiating the list-walking module load and the list-adding module load concurrently, and `trace_event_eval_update()` calls `cond_resched()` on every iteration over a list of thousands of events, making the preemption window very wide and the race practically winnable. Per race-condition guidance, attacker-created races are Low.\nPR:L - Both sides of the race are reachable by an unprivileged local user via kernel module autoloading (e.g. concurrent `socket(AF_RXRPC,\u2026)` loading rxrpc, whose TRACE_DEFINE_ENUM maps drive the unlocked walk, and `socket(AF_INET,SOCK_STREAM,IPPROTO_SCTP)` loading sctp, whose trace events drive the unlocked list_add), and containers granted CAP_SYS_MODULE can trigger it repeatably. No authentication beyond an ordinary local account is required.\nUI:N - The attacker triggers both concurrent module loads themselves; no victim action, mount, or file open by another user is needed.\nS:U - The corruption and its consequences are confined to kernel memory within the same security authority; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - Following a torn list pointer, the walker dereferences an arbitrary `struct trace_event_call`, reading `call-\u003eprint_fmt` and traversing `call-\u003eclass-\u003efields` from wild addresses, and the resulting strings are persisted into `field-\u003etype`/`print_fmt` which are readable through `/sys/kernel/tracing/events/*/format`, giving kernel memory disclosure.\nI:H - `eval_replace()` performs in-place `snprintf`/`memmove` writes through the wild `call-\u003eprint_fmt` pointer and `update_event_fields()` stores `field-\u003etype = str`, yielding out-of-bounds writes; additionally `call-\u003emodule` is assigned after the unlocked list_add, so a racing walker can attach strings to a stale module pointer that a later unload frees, producing a use-after-free suitable for control-flow hijacking.\nA:H - The commit states outright that the unsynchronized list_add \"can corrupt the walking of the list ... and crash the kernel\"; the reported failure is a kernel oops/panic, and dereferencing a stale next pointer reliably faults."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/mcde: Fix refcount leak in mcde_dsi_bind
Every iteration of for_each_available_child_of_node() decrements
the reference counter of the previous node. There is no decrement
when break out from the loop and results in refcount leak.
Add missing of_node_put() to fix this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc2: fix a devres leak in hw_enable upon suspend resume
Each time the platform goes to low power, PM suspend / resume routines
call: __dwc2_lowlevel_hw_enable -> devm_add_action_or_reset().
This adds a new devres each time.
This may also happen at runtime, as dwc2_lowlevel_hw_enable() can be
called from udc_start().
This can be seen with tracing:
- echo 1 > /sys/kernel/debug/tracing/events/dev/devres_log/enable
- go to low power
- cat /sys/kernel/debug/tracing/trace
A new "ADD" entry is found upon each low power cycle:
... devres_log: 49000000.usb-otg ADD 82a13bba devm_action_release (8 bytes)
... devres_log: 49000000.usb-otg ADD 49889daf devm_action_release (8 bytes)
...
A second issue is addressed here:
- regulator_bulk_enable() is called upon each PM cycle (suspend/resume).
- regulator_bulk_disable() never gets called.
So the reference count for these regulators constantly increase, by one
upon each low power cycle, due to missing regulator_bulk_disable() call
in __dwc2_lowlevel_hw_disable().
The original fix that introduced the devm_add_action_or_reset() call,
fixed an issue during probe, that happens due to other errors in
dwc2_driver_probe() -> dwc2_core_reset(). Then the probe fails without
disabling regulators, when dr_mode == USB_DR_MODE_PERIPHERAL.
Rather fix the error path: disable all the low level hardware in the
error path, by using the "hsotg->ll_hw_enabled" flag. Checking dr_mode
has been introduced to avoid a dual call to dwc2_lowlevel_hw_disable().
"ll_hw_enabled" should achieve the same (and is used currently in the
remove() routine).

Summary
In the Linux kernel, the following vulnerability has been resolved:
mptcp: plug races between subflow fail and subflow creation
We have races similar to the one addressed by the previous patch between
subflow failing and additional subflow creation. They are just harder to
trigger.
The solution is similar. Use a separate flag to track the condition
'socket state prevent any additional subflow creation' protected by the
fallback lock.
The socket fallback makes such flag true, and also receiving or sending
an MP_FAIL option.
The field 'allow_infinite_fallback' is now always touched under the
relevant lock, we can drop the ONCE annotation on write.

No local access is needed; any host reaching an MPTCP-enabled listener (or an MPTCP client connecting to a malicious server) can trigger it.\nAC:L - The attacker generates and times both sides of the race itself \u2014 it sends the MP_FAIL option on the initial subflow while concurrently completing MP_JOIN handshakes for additional subflows, and can repeat this unboundedly across many parallel connections. Nothing in the trigger depends on state outside the attacker\u0027s control, so despite the window being narrow this is attacker-created, not attacker-independent.\nPR:N - The only requirement is a fully established MPTCP connection to the target, which any unauthenticated peer can create; the default in-kernel path manager (`subflows_max = 2`, `allow_join_initial_addr_port = 1`) accepts the extra MP_JOIN subflows with no administrative configuration. No credentials on the victim are needed at any point.\nUI:N - Everything happens inside the kernel\u0027s TCP/MPTCP receive and transmit paths on packets the attacker sends; no action by a local user or administrator is required.\nS:U - The corrupted state and its consequences are confined to the kernel\u0027s own MPTCP socket and the connection it serves \u2014 there is no crossing into another security authority such as a VM, IOMMU, or sandbox boundary.\nC:L - The `WARN_ON_ONCE` in `__mptcp_do_fallback()` is reachable remotely and dumps register contents, kernel text/stack addresses and a call trace to the kernel log, leaking KASLR-relevant pointers; additionally the corrupted fallback state makes the receive path splice subflow data into the msk stream using stale mapping metadata with DSS and checksum validation skipped. There is no arbitrary kernel-memory read primitive, so the disclosure is bounded.\nI:H - The bug breaks the core MPTCP invariant that fallback happens only on a single-subflow connection, so the kernel reassembles the byte stream from multiple subflows without DSS mapping or checksum validation and force-advances `msk-\u003esnd_una` to `snd_nxt`, silently discarding never-delivered data as acknowledged. The application is handed a corrupted stream and told its writes succeeded, with no error indication \u2014 a complete loss of integrity for the data carried over the connection, on top of the violated kernel socket-state invariants.\nA:H - Winning the race hits `WARN_ON_ONCE(!READ_ONCE(msk-\u003eallow_infinite_fallback))` in softirq context on all affected trees, which is an immediate kernel panic on the widely deployed `panic_on_warn=1` configurations; even without it the connection is left permanently desynchronized, and once `msk-\u003efirst` is gone `mptcp_sched_get_send()` returns -EINVAL so the socket wedges with queued data pinning memory, repeatable across unlimited connections."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, cpumap: Make sure kthread is running before map update returns
The following warning was reported when running stress-mode enabled
xdp_redirect_cpu with some RT threads:
------------[ cut here ]------------
WARNING: CPU: 4 PID: 65 at kernel/bpf/cpumap.c:135
CPU: 4 PID: 65 Comm: kworker/4:1 Not tainted 6.5.0-rc2+ #1
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996)
Workqueue: events cpu_map_kthread_stop
RIP: 0010:put_cpu_map_entry+0xda/0x220

</TASK>
The root cause is the same as commit 436901649731 ("bpf: cpumap: Fix memory
leak in cpu_map_update_elem"). The kthread is stopped prematurely by
kthread_stop() in cpu_map_kthread_stop(), and kthread() doesn't call
cpu_map_kthread_run() at all but XDP program has already queued some
frames or skbs into ptr_ring. So when __cpu_map_ring_cleanup() checks
the ptr_ring, it will find it was not emptied and report a warning.
An alternative fix is to use __cpu_map_ring_cleanup() to drop these
pending frames or skbs when kthread_stop() returns -EINTR, but it may
confuse the user, because these frames or skbs have been handled
correctly by XDP program. So instead of dropping these frames or skbs,
just make sure the per-cpu kthread is running before
__cpu_map_entry_alloc() returns.
After apply the fix, the error handle for kthread_stop() will be
unnecessary because it will always return 0, so just remove it.

Per kernel scoring guidance BPF map manipulation is Local.\nAC:L - The attacker drives both sides of the race: it produces the queued frames/skbs (self-generated traffic through a generic-mode XDP redirect on a veth/lo it controls) and issues the map update that calls `kthread_stop()`, and it chooses the CPU the kthread is bound to so it can starve it with spinner threads or a softirq flood. No special kernel config is required, and the update/delete loop can be repeated indefinitely until the race is won.\nPR:L - Creating the cpumap needs `bpf_capable()` and the XDP program needs `CAP_NET_ADMIN`, but these are delegatable non-root capabilities routinely granted to unprivileged XDP dataplane daemons/containers, not administrative control over the kernel. Consistent with kernel CNA scoring of comparable CAP_BPF/CAP_NET_ADMIN XDP and devmap/cpumap issues (e.g. CVE-2026-23294, CVE-2025-21808).\nUI:N - The entire sequence \u2014 map create, XDP attach, traffic generation, and the update/delete that races the kthread \u2014 is performed by the attacker\u0027s own process. No victim action is involved.\nS:U - The corruption and crash occur inside the kernel itself, within the same security authority as the vulnerable component. There is no VM, IOMMU, or sandbox boundary crossed.\nC:H - In generic/skb XDP mode the leftover ring entries are tagged `sk_buff` pointers passed to `xdp_return_frame()` as `struct xdp_frame *`; when the misread `flags` field sets `XDP_FLAGS_HAS_FRAGS`, `xdp_get_shared_info_from_frame()` builds a wild pointer from misread `data`/`frame_sz` and reads `sinfo-\u003enr_frags` and the frag array out of bounds. This type confusion yields an uncontrolled kernel-memory read primitive whose results feed `page_address()`/`__xdp_return()`.\nI:H - The same type confusion drives `__xdp_return()` with a garbage `mem.type` and garbage `data`, reaching `page_frag_free()`, `put_page()`, or `page_pool_put_full_page()` on uncontrolled pointers \u2014 arbitrary page refcount decrements that can prematurely free live pages and be leveraged into a write primitive. Type confusion / memory corruption of this class is scored High.\nA:H - The bug reliably produces a `WARN_ON_ONCE` splat in `__cpu_map_ring_cleanup()` (kernel panic under `panic_on_warn`), and the follow-on wild-pointer dereference in `xdp_return_frame()`/`__xdp_return()` causes a GPF/oops. It also leaks the pending skbs on every occurrence."

Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: don't reset unchangable mount option in f2fs_remount()
syzbot reports a bug as below:

The root cause is race condition as below:
- since it tries to remount rw filesystem, so that do_remount won't
call sb_prepare_remount_readonly to block fallocate, there may be race
condition in between remount and fallocate.
- in f2fs_remount(), default_options() will reset mount option to default
one, and then update it based on result of parse_options(), so there is
a hole which race condition can happen.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: Intel: avs: Fix potential buffer overflow by snprintf()
snprintf() returns the would-be-filled size when the string overflows
the given buffer size, hence using this value may result in a buffer
overflow (although it's unrealistic).
This patch replaces it with a safer version, scnprintf() for papering
over such a potential issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: netem: account for backlog updates from child qdisc
In general, 'qlen' of any classful qdisc should keep track of the
number of packets that the qdisc itself and all of its children holds.
In case of netem, 'qlen' only accounts for the packets in its internal
tfifo. When netem is used with a child qdisc, the child qdisc can use
'qdisc_tree_reduce_backlog' to inform its parent, netem, about created
or dropped SKBs. This function updates 'qlen' and the backlog statistics
of netem, but netem does not account for changes made by a child qdisc.
'qlen' then indicates the wrong number of packets in the tfifo.
If a child qdisc creates new SKBs during enqueue and informs its parent
about this, netem's 'qlen' value is increased. When netem dequeues the
newly created SKBs from the child, the 'qlen' in netem is not updated.
If 'qlen' reaches the configured sch->limit, the enqueue function stops
working, even though the tfifo is not full.
Reproduce the bug:
Ensure that the sender machine has GSO enabled. Configure netem as root
qdisc and tbf as its child on the outgoing interface of the machine
as follows:
$ tc qdisc add dev <oif> root handle 1: netem delay 100ms limit 100
$ tc qdisc add dev <oif> parent 1:0 tbf rate 50Mbit burst 1542 latency 50ms
Send bulk TCP traffic out via this interface, e.g., by running an iPerf3
client on the machine. Check the qdisc statistics:
$ tc -s qdisc show dev <oif>
Statistics after 10s of iPerf3 TCP test before the fix (note that
netem's backlog > limit, netem stopped accepting packets):
qdisc netem 1: root refcnt 2 limit 1000 delay 100ms
Sent 2767766 bytes 1848 pkt (dropped 652, overlimits 0 requeues 0)
backlog 4294528236b 1155p requeues 0
qdisc tbf 10: parent 1:1 rate 50Mbit burst 1537b lat 50ms
Sent 2767766 bytes 1848 pkt (dropped 327, overlimits 7601 requeues 0)
backlog 0b 0p requeues 0
Statistics after the fix:
qdisc netem 1: root refcnt 2 limit 1000 delay 100ms
Sent 37766372 bytes 24974 pkt (dropped 9, overlimits 0 requeues 0)
backlog 0b 0p requeues 0
qdisc tbf 10: parent 1:1 rate 50Mbit burst 1537b lat 50ms
Sent 37766372 bytes 24974 pkt (dropped 327, overlimits 96017 requeues 0)
backlog 0b 0p requeues 0
tbf segments the GSO SKBs (tbf_segment) and updates the netem's 'qlen'.
The interface fully stops transferring packets and "locks". In this case,
the child qdisc and tfifo are empty, but 'qlen' indicates the tfifo is at
its limit and no more packets are accepted.
This patch adds a counter for the entries in the tfifo. Netem's 'qlen' is
only decreased when a packet is returned by its dequeue function, and not
during enqueuing into the child qdisc. External updates to 'qlen' are thus
accounted for and only the behavior of the backlog statistics changes. As
in other qdiscs, 'qlen' then keeps track of how many packets are held in
netem and all of its children. As before, sch->limit remains as the
maximum number of packets in the tfifo. The same applies to netem's
backlog statistics.

When netem is used with a child qdisc, the child qdisc can use\n\u0027qdisc_tree_reduce_backlog\u0027 to inform its parent, netem, about created\nor dropped SKBs. This function updates \u0027qlen\u0027 and the backlog statistics\nof netem, but netem does not account for changes made by a child qdisc.\n\u0027qlen\u0027 then indicates the wrong number of packets in the tfifo.\nIf a child qdisc creates new SKBs during enqueue and informs its parent\nabout this, netem\u0027s \u0027qlen\u0027 value is increased. When netem dequeues the\nnewly created SKBs from the child, the \u0027qlen\u0027 in netem is not updated.\nIf \u0027qlen\u0027 reaches the configured sch-\u003elimit, the enqueue function stops\nworking, even though the tfifo is not full.\n\nReproduce the bug:\nEnsure that the sender machine has GSO enabled. Configure netem as root\nqdisc and tbf as its child on the outgoing interface of the machine\nas follows:\n$ tc qdisc add dev \u003coif\u003e root handle 1: netem delay 100ms limit 100\n$ tc qdisc add dev \u003coif\u003e parent 1:0 tbf rate 50Mbit burst 1542 latency 50ms\n\nSend bulk TCP traffic out via this interface, e.g., by running an iPerf3\nclient on the machine. Check the qdisc statistics:\n$ tc -s qdisc show dev \u003coif\u003e\n\nStatistics after 10s of iPerf3 TCP test before the fix (note that\nnetem\u0027s backlog \u003e limit, netem stopped accepting packets):\nqdisc netem 1: root refcnt 2 limit 1000 delay 100ms\n Sent 2767766 bytes 1848 pkt (dropped 652, overlimits 0 requeues 0)\n backlog 4294528236b 1155p requeues 0\nqdisc tbf 10: parent 1:1 rate 50Mbit burst 1537b lat 50ms\n Sent 2767766 bytes 1848 pkt (dropped 327, overlimits 7601 requeues 0)\n backlog 0b 0p requeues 0\n\nStatistics after the fix:\nqdisc netem 1: root refcnt 2 limit 1000 delay 100ms\n Sent 37766372 bytes 24974 pkt (dropped 9, overlimits 0 requeues 0)\n backlog 0b 0p requeues 0\nqdisc tbf 10: parent 1:1 rate 50Mbit burst 1537b lat 50ms\n Sent 37766372 bytes 24974 pkt (dropped 327, overlimits 96017 requeues 0)\n backlog 0b 0p requeues 0\n\ntbf segments the GSO SKBs (tbf_segment) and updates the netem\u0027s \u0027qlen\u0027.\nThe interface fully stops transferring packets and \"locks\". In this case,\nthe child qdisc and tfifo are empty, but \u0027qlen\u0027 indicates the tfifo is at\nits limit and no more packets are accepted.\n\nThis patch adds a counter for the entries in the tfifo. Netem\u0027s \u0027qlen\u0027 is\nonly decreased when a packet is returned by its dequeue function, and not\nduring enqueuing into the child qdisc. External updates to \u0027qlen\u0027 are thus\naccounted for and only the behavior of the backlog statistics changes. As\nin other qdiscs, \u0027qlen\u0027 then keeps track of how many packets are held in\nnetem and all of its children. As before, sch-\u003elimit remains as the\nmaximum number of packets in the tfifo. The same applies to netem\u0027s\nbacklog statistics."

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: vhci: Prevent use-after-free by removing debugfs files early
Move the creation of debugfs files into a dedicated function, and ensure
they are explicitly removed during vhci_release(), before associated
data structures are freed.
Previously, debugfs files such as "force_suspend", "force_wakeup", and
others were created under hdev->debugfs but not removed in
vhci_release(). Since vhci_release() frees the backing vhci_data
structure, any access to these files after release would result in
use-after-free errors.
Although hdev->debugfs is later freed in hci_release_dev(), user can
access files after vhci_data is freed but before hdev->debugfs is
released.

Summary
In the Linux kernel, the following vulnerability has been resolved:
lwt: Fix return values of BPF xmit ops
BPF encap ops can return different types of positive values, such like
NET_RX_DROP, NET_XMIT_CN, NETDEV_TX_BUSY, and so on, from function
skb_do_redirect and bpf_lwt_xmit_reroute. At the xmit hook, such return
values would be treated implicitly as LWTUNNEL_XMIT_CONTINUE in
ip(6)_finish_output2. When this happens, skbs that have been freed would
continue to the neighbor subsystem, causing use-after-free bug and
kernel crashes.
To fix the incorrect behavior, skb_do_redirect return values can be
simply discarded, the same as tc-egress behavior. On the other hand,
bpf_lwt_xmit_reroute returns useful errors to local senders, e.g. PMTU
information. Thus convert its return values to avoid the conflict with
LWTUNNEL_XMIT_CONTINUE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: block range must be validated before use in ext4_mb_clear_bb()
Block range to free is validated in ext4_free_blocks() using
ext4_inode_block_valid() and then it's passed to ext4_mb_clear_bb().
However in some situations on bigalloc file system the range might be
adjusted after the validation in ext4_free_blocks() which can lead to
troubles on corrupted file systems such as one found by syzkaller that
resulted in the following BUG
kernel BUG at fs/ext4/ext4.h:3319!

Fix it by making sure that the block range is properly validated before
used every time it changes in ext4_free_blocks() or ext4_mb_clear_bb().

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/sseu: fix max_subslices array-index-out-of-bounds access
It seems that commit bc3c5e0809ae ("drm/i915/sseu: Don't try to store EU
mask internally in UAPI format") exposed a potential out-of-bounds
access, reported by UBSAN as following on a laptop with a gen 11 i915
card:
UBSAN: array-index-out-of-bounds in drivers/gpu/drm/i915/gt/intel_sseu.c:65:27
index 6 is out of range for type 'u16 [6]'
CPU: 2 PID: 165 Comm: systemd-udevd Not tainted 6.2.0-9-generic #9-Ubuntu
Hardware name: Dell Inc. XPS 13 9300/077Y9N, BIOS 1.11.0 03/22/2022

According to the definition of sseu_dev_info, eu_mask->hsw is limited to
a maximum of GEN_MAX_SS_PER_HSW_SLICE (6) sub-slices, but
gen11_sseu_info_init() can potentially set 8 sub-slices, in the
!IS_JSL_EHL(gt->i915) case.
Fix this by reserving up to 8 slots for max_subslices in the eu_mask
struct.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_tunnel: fix geneve_opt type confusion addition
When handling multiple NFTA_TUNNEL_KEY_OPTS_GENEVE attributes, the
parsing logic should place every geneve_opt structure one by one
compactly. Hence, when deciding the next geneve_opt position, the
pointer addition should be in units of char *.
However, the current implementation erroneously does type conversion
before the addition, which will lead to heap out-of-bounds write.

Table creation, object creation, and module autoload all succeed inside that namespace.\nUI:N - The attacker performs the entire sequence themselves via socket syscalls; no action by any other user or administrator is needed.\nS:U - The corruption stays within the kernel\u0027s own memory and security authority, yielding standard local privilege escalation rather than crossing a virtualization or IOMMU boundary.\nC:H - The mirrored bug in nft_tunnel_opts_dump() performs an out-of-bounds read whose offset and length both come from adjacent heap memory, and nla_put() copies that data into the netlink reply delivered to userspace, disclosing arbitrary kernel heap contents. The OOB write additionally enables full memory disclosure via corrupted neighbouring objects.\nI:H - This is an out-of-bounds heap write with an attacker-controlled destination (up to ~1000 bytes past the start of a ~400-byte kmalloc-512 object) and up to 124 bytes of fully attacker-controlled content, allowing corruption of sprayed adjacent slab objects and control-flow hijacking for privilege escalation.\nA:H - The KASAN report in the fix commit shows a 124-byte slab-out-of-bounds write; corrupting neighbouring slab objects reliably produces kernel oops/panic, and the trigger can be repeated at will from an unprivileged namespace."

Summary
In the Linux kernel, the following vulnerability has been resolved:
netlink: fix potential deadlock in netlink_set_err()
syzbot reported a possible deadlock in netlink_set_err() [1]
A similar issue was fixed in commit 1d482e666b8e ("netlink: disable IRQs
for netlink_lock_table()") in netlink_lock_table()
This patch adds IRQ safety to netlink_set_err() and __netlink_diag_dump()
which were not covered by cited commit.
[1]
WARNING: possible irq lock inversion dependency detected
6.4.0-rc6-syzkaller-00240-g4e9f0ec38852 #0 Not tainted
syz-executor.2/23011 just changed the state of lock:
ffffffff8e1a7a58 (nl_table_lock){.+.?}-{2:2}, at: netlink_set_err+0x2e/0x3a0 net/netlink/af_netlink.c:1612
but this lock was taken by another, SOFTIRQ-safe lock in the past:
(&local->queue_stop_reason_lock){..-.}-{2:2}
and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
Possible interrupt unsafe locking scenario:

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: MGMT: Fix possible UAFs
This attemps to fix possible UAFs caused by struct mgmt_pending being
freed while still being processed like in the following trace, in order
to fix mgmt_pending_valid is introduce and use to check if the
mgmt_pending hasn't been removed from the pending list, on the complete
callbacks it is used to check and in addtion remove the cmd from the list
while holding mgmt_pending_lock to avoid TOCTOU problems since if the cmd
is left on the list it can still be accessed and freed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Destroy KFD debugfs after destroy KFD wq
Since KFD proc content was moved to kernel debugfs, we can't destroy KFD
debugfs before kfd_process_destroy_wq. Move kfd_process_destroy_wq prior
to kfd_debugfs_fini to fix a kernel NULL pointer problem. It happens
when /sys/kernel/debug/kfd was already destroyed in kfd_debugfs_fini but
kfd_process_destroy_wq calls kfd_debugfs_remove_process. This line
debugfs_remove_recursive(entry->proc_dentry);
tries to remove /sys/kernel/debug/kfd/proc/<pid> while
/sys/kernel/debug/kfd is already gone. It hangs the kernel by kernel
NULL pointer.
(cherry picked from commit 0333052d90683d88531558dcfdbf2525cc37c233)

Summary
In the Linux kernel, the following vulnerability has been resolved:
ceph: don't leak snap_rwsem in handle_cap_grant
When handle_cap_grant is called on an IMPORT op, then the snap_rwsem is
held and the function is expected to release it before returning. It
currently fails to do that in all cases which could lead to a deadlock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: ccp - Use kzalloc for sev ioctl interfaces to prevent kernel memory leak
For some sev ioctl interfaces, input may be passed that is less than or
equal to SEV_FW_BLOB_MAX_SIZE, but larger than the data that PSP
firmware returns. In this case, kmalloc will allocate memory that is the
size of the input rather than the size of the data. Since PSP firmware
doesn't fully overwrite the buffer, the sev ioctl interfaces with the
issue may return uninitialized slab memory.
Currently, all of the ioctl interfaces in the ccp driver are safe, but
to prevent future problems, change all ioctl interfaces that allocate
memory with kmalloc to use kzalloc and memset the data buffer to zero
in sev_ioctl_do_platform_status.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix OOB read when checking dotdot dir
Mounting a corrupted filesystem with directory which contains '.' dir
entry with rec_len == block size results in out-of-bounds read (later
on, when the corrupted directory is removed).
ext4_empty_dir() assumes every ext4 directory contains at least '.'
and '..' as directory entries in the first data block. It first loads
the '.' dir entry, performs sanity checks by calling ext4_check_dir_entry()
and then uses its rec_len member to compute the location of '..' dir
entry (in ext4_next_entry). It assumes the '..' dir entry fits into the
same data block.
If the rec_len of '.' is precisely one block (4KB), it slips through the
sanity checks (it is considered the last directory entry in the data
block) and leaves "struct ext4_dir_entry_2 *de" point exactly past the
memory slot allocated to the data block. The following call to
ext4_check_dir_entry() on new value of de then dereferences this pointer
which results in out-of-bounds mem access.
Fix this by extending __ext4_check_dir_entry() to check for '.' dir
entries that reach the end of data block. Make sure to ignore the phony
dir entries for checksum (by checking name_len for non-zero).
Note: This is reported by KASAN as use-after-free in case another
structure was recently freed from the slot past the bound, but it is
really an OOB read.
This issue was found by syzkaller tool.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\next4: fix OOB read when checking dotdot dir\n\nMounting a corrupted filesystem with directory which contains \u0027.\u0027 dir\nentry with rec_len == block size results in out-of-bounds read (later\non, when the corrupted directory is removed).\n\next4_empty_dir() assumes every ext4 directory contains at least \u0027.\u0027\nand \u0027..\u0027 as directory entries in the first data block. It first loads\nthe \u0027.\u0027 dir entry, performs sanity checks by calling ext4_check_dir_entry()\nand then uses its rec_len member to compute the location of \u0027..\u0027 dir\nentry (in ext4_next_entry). It assumes the \u0027..\u0027 dir entry fits into the\nsame data block.\n\nIf the rec_len of \u0027.\u0027 is precisely one block (4KB), it slips through the\nsanity checks (it is considered the last directory entry in the data\nblock) and leaves \"struct ext4_dir_entry_2 *de\" point exactly past the\nmemory slot allocated to the data block. The following call to\next4_check_dir_entry() on new value of de then dereferences this pointer\nwhich results in out-of-bounds mem access.\n\nFix this by extending __ext4_check_dir_entry() to check for \u0027.\u0027 dir\nentries that reach the end of data block. Make sure to ignore the phony\ndir entries for checksum (by checking name_len for non-zero).\n\nNote: This is reported by KASAN as use-after-free in case another\nstructure was recently freed from the slot past the bound, but it is\nreally an OOB read.\n\nThis issue was found by syzkaller tool.\n\nCall Trace:\n[ 38.594108] BUG: KASAN: slab-use-after-free in __ext4_check_dir_entry+0x67e/0x710\n[ 38.594649] Read of size 2 at addr ffff88802b41a004 by task syz-executor/5375\n[ 38.595158]\n[ 38.595288] CPU: 0 UID: 0 PID: 5375 Comm: syz-executor Not tainted 6.14.0-rc7 #1\n[ 38.595298] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.3-0-ga6ed6b701f0a-prebuilt.qemu.org 04/01/2014\n[ 38.595304] Call Trace:\n[ 38.595308] \u003cTASK\u003e\n[ 38.595311] dump_stack_lvl+0xa7/0xd0\n[ 38.595325] print_address_description.constprop.0+0x2c/0x3f0\n[ 38.595339] ? __ext4_check_dir_entry+0x67e/0x710\n[ 38.595349] print_report+0xaa/0x250\n[ 38.595359] ? __ext4_check_dir_entry+0x67e/0x710\n[ 38.595368] ? kasan_addr_to_slab+0x9/0x90\n[ 38.595378] kasan_report+0xab/0xe0\n[ 38.595389] ? __ext4_check_dir_entry+0x67e/0x710\n[ 38.595400] __ext4_check_dir_entry+0x67e/0x710\n[ 38.595410] ext4_empty_dir+0x465/0x990\n[ 38.595421] ? __pfx_ext4_empty_dir+0x10/0x10\n[ 38.595432] ext4_rmdir.part.0+0x29a/0xd10\n[ 38.595441] ? __dquot_initialize+0x2a7/0xbf0\n[ 38.595455] ? __pfx_ext4_rmdir.part.0+0x10/0x10\n[ 38.595464] ? __pfx___dquot_initialize+0x10/0x10\n[ 38.595478] ? down_write+0xdb/0x140\n[ 38.595487] ? __pfx_down_write+0x10/0x10\n[ 38.595497] ext4_rmdir+0xee/0x140\n[ 38.595506] vfs_rmdir+0x209/0x670\n[ 38.595517] ? lookup_one_qstr_excl+0x3b/0x190\n[ 38.595529] do_rmdir+0x363/0x3c0\n[ 38.595537] ? __pfx_do_rmdir+0x10/0x10\n[ 38.595544] ? strncpy_from_user+0x1ff/0x2e0\n[ 38.595561] __x64_sys_unlinkat+0xf0/0x130\n[ 38.595570] do_syscall_64+0x5b/0x180\n[ 38.595583] entry_SYSCALL_64_after_hwframe+0x76/0x7e"

Local attack vector scores higher than physical and correctly models USB/auto-mount and loop-mount delivery.\nAC:L - The condition is fully deterministic and entirely attacker-authored \u2014 setting the `.` entry\u0027s `rec_len` to exactly the block size in the image reliably slips past every sanity check in `__ext4_check_dir_entry()` and lands `de` past the block on every attempt. No race, timing, or uncontrolled memory-layout requirement.\nPR:L - Once the image is mounted (via udisks2/GNOME auto-mount of removable media on desktops and kiosks, or an fstab `user` entry), any unprivileged local user with ordinary access to the mount can invoke `rmdir` and reach `ext4_empty_dir()`; no capability check gates the path.\nUI:N - In the auto-mount scenario the attacker performs both steps themselves \u2014 inserting the media triggers the mount automatically and the same attacker issues the `rmdir` \u2014 so no action by a separate user is required.\nS:U - The out-of-bounds access, the disclosure, and the panic all occur within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The read reaches into the adjacent slab object/page and its contents are exfiltrated to userspace-visible dmesg through `ext4_error_inode()`, which prints the out-of-bounds `inode` and `rec_len` fields verbatim. The operation is cheaply repeatable and the neighbouring slot can be heap-groomed, making it a practical kernel heap/pointer disclosure primitive rather than a bounded one-shot leak.\nI:H - Data read out of bounds directly controls subsequent logic \u2014 if the adjacent heap bytes decode as a valid `..` entry, `ext4_empty_dir()` wrongly reports the directory empty and `rmdir`/`rename` proceeds to unlink a non-empty directory, and the OOB `rec_len` drives the following offset walk. KASAN classifies the access as a use-after-free on the neighbouring freed object, so attacker-groomed heap state translates into corrupted filesystem-metadata operations.\nA:H - The error path is reached with the attacker-controlled superblock, and `s_errors = EXT4_ERRORS_PANIC` (`fs/ext4/super.c:4364`) makes `ext4_error_inode()` call `panic()` at `super.c:735`, giving a guaranteed kernel panic. Independently, the read past the block can fault on an unmapped or poisoned page, and on debug/KASAN kernels it is an immediate BUG."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: mpt3sas: Fix NULL pointer access in mpt3sas_transport_port_add()
Port is allocated by sas_port_alloc_num() and rphy is allocated by either
sas_end_device_alloc() or sas_expander_alloc(), all of which may return
NULL. So we need to check the rphy to avoid possible NULL pointer access.
If sas_rphy_add() returned with failure, rphy is set to NULL. We would
access the rphy in the following lines which would also result NULL pointer
access.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bus: fsl-mc: don't assume child devices are all fsl-mc devices
Changes in VFIO caused a pseudo-device to be created as child of
fsl-mc devices causing a crash [1] when trying to bind a fsl-mc
device to VFIO. Fix this by checking the device type when enumerating
fsl-mc child devices.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: sch_sfq: move the limit validation
It is not sufficient to directly validate the limit on the data that
the user passes as it can be updated based on how the other parameters
are changed.
Move the check at the end of the configuration update process to also
catch scenarios where the limit is indirectly updated, for example
with the following configurations:
tc qdisc add dev dummy0 handle 1: root sfq limit 2 flows 1 depth 1
tc qdisc add dev dummy0 handle 1: root sfq limit 2 flows 1 divisor 1
This fixes the following syzkaller reported crash:

hwmon: (gpio-fan) Fix array out of bounds access
The driver does not check if the cooling state passed to
gpio_fan_set_cur_state() exceeds the maximum cooling state as
stored in fan_data->num_speeds. Since the cooling state is later
used as an array index in set_fan_speed(), an array out of bounds
access can occur.
This can be exploited by setting the state of the thermal cooling device
to arbitrary values, causing for example a kernel oops when unavailable
memory is accessed this way.
Example kernel oops:

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix steering rules cleanup
vport's mc, uc and multicast rules are not deleted in teardown path when
EEH happens. Since the vport's promisc settings(uc, mc and all) in
firmware are reset after EEH, mlx5 driver will try to delete the above
rules in the initialization path. This cause kernel crash because these
software rules are no longer valid.
Fix by nullifying these rules right after delete to avoid accessing any dangling
pointers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: Fix possible leaked pernet namespace in smc_init()
In smc_init(), register_pernet_subsys(&smc_net_stat_ops) is called
without any error handling.
If it fails, registering of &smc_net_ops won't be reverted.
And if smc_nl_init() fails, &smc_net_stat_ops itself won't be reverted.
This leaves wild ops in subsystem linkedlist and when another module
tries to call register_pernet_operations() it triggers page fault:
BUG: unable to handle page fault for address: fffffbfff81b964c
RIP: 0010:register_pernet_operations+0x1b9/0x5f0
Call Trace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Explicitly check accesses to bpf_sock_addr
Syzkaller found a kernel warning on the following sock_addr program:
0: r0 = 0
1: r2 = *(u32 *)(r1 +60)
2: exit
which triggers:
verifier bug: error during ctx access conversion (0)
This is happening because offset 60 in bpf_sock_addr corresponds to an
implicit padding of 4 bytes, right after msg_src_ip4. Access to this
padding isn't rejected in sock_addr_is_valid_access and it thus later
fails to convert the access.
This patch fixes it by explicitly checking the various fields of
bpf_sock_addr in sock_addr_is_valid_access.
I checked the other ctx structures and is_valid_access functions and
didn't find any other similar cases. Other cases of (properly handled)
padding are covered in new tests in a subsequent patch.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Make bpf_refcount_acquire fallible for non-owning refs
This patch fixes an incorrect assumption made in the original
bpf_refcount series [0], specifically that the BPF program calling
bpf_refcount_acquire on some node can always guarantee that the node is
alive. In that series, the patch adding failure behavior to rbtree_add
and list_push_{front, back} breaks this assumption for non-owning
references.
Consider the following program:
n = bpf_kptr_xchg(&mapval, NULL);
/* skip error checking */
bpf_spin_lock(&l);
if(bpf_rbtree_add(&t, &n->rb, less)) {
bpf_refcount_acquire(n);
/* Failed to add, do something else with the node */
}
bpf_spin_unlock(&l);
It's incorrect to assume that bpf_refcount_acquire will always succeed in this
scenario. bpf_refcount_acquire is being called in a critical section
here, but the lock being held is associated with rbtree t, which isn't
necessarily the lock associated with the tree that the node is already
in. So after bpf_rbtree_add fails to add the node and calls bpf_obj_drop
in it, the program has no ownership of the node's lifetime. Therefore
the node's refcount can be decr'd to 0 at any time after the failing
rbtree_add. If this happens before the refcount_acquire above, the node
might be free'd, and regardless refcount_acquire will be incrementing a
0 refcount.
Later patches in the series exercise this scenario, resulting in the
expected complaint from the kernel (without this patch's changes):
refcount_t: addition on 0; use-after-free.

<TASK>
bpf_refcount_acquire_impl+0xb5/0xc0
(rest of output snipped)
The patch addresses this by changing bpf_refcount_acquire_impl to use
refcount_inc_not_zero instead of refcount_inc and marking
bpf_refcount_acquire KF_RET_NULL.
For owning references, though, we know the above scenario is not possible
and thus that bpf_refcount_acquire will always succeed. Some verifier
bookkeeping is added to track "is input owning ref?" for bpf_refcount_acquire
calls and return false from is_kfunc_ret_null for bpf_refcount_acquire on
owning refs despite it being marked KF_RET_NULL.
Existing selftests using bpf_refcount_acquire are modified where
necessary to NULL-check its return value.

If this happens before the refcount_acquire above, the node\nmight be free\u0027d, and regardless refcount_acquire will be incrementing a\n0 refcount.\n\nLater patches in the series exercise this scenario, resulting in the\nexpected complaint from the kernel (without this patch\u0027s changes):\n\n refcount_t: addition on 0; use-after-free.\n WARNING: CPU: 1 PID: 207 at lib/refcount.c:25 refcount_warn_saturate+0xbc/0x110\n Modules linked in: bpf_testmod(O)\n CPU: 1 PID: 207 Comm: test_progs Tainted: G O 6.3.0-rc7-02231-g723de1a718a2-dirty #371\n Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.15.0-0-g2dd4b9b3f840-prebuilt.qemu.org 04/01/2014\n RIP: 0010:refcount_warn_saturate+0xbc/0x110\n Code: 6f 64 f6 02 01 e8 84 a3 5c ff 0f 0b eb 9d 80 3d 5e 64 f6 02 00 75 94 48 c7 c7 e0 13 d2 82 c6 05 4e 64 f6 02 01 e8 64 a3 5c ff \u003c0f\u003e 0b e9 7a ff ff ff 80 3d 38 64 f6 02 00 0f 85 6d ff ff ff 48 c7\n RSP: 0018:ffff88810b9179b0 EFLAGS: 00010082\n RAX: 0000000000000000 RBX: 0000000000000002 RCX: 0000000000000000\n RDX: 0000000000000202 RSI: 0000000000000008 RDI: ffffffff857c3680\n RBP: ffff88810027d3c0 R08: ffffffff8125f2a4 R09: ffff88810b9176e7\n R10: ffffed1021722edc R11: 746e756f63666572 R12: ffff88810027d388\n R13: ffff88810027d3c0 R14: ffffc900005fe030 R15: ffffc900005fe048\n FS: 00007fee0584a700(0000) GS:ffff88811b280000(0000) knlGS:0000000000000000\n CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n CR2: 00005634a96f6c58 CR3: 0000000108ce9002 CR4: 0000000000770ee0\n DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n PKRU: 55555554\n Call Trace:\n \u003cTASK\u003e\n bpf_refcount_acquire_impl+0xb5/0xc0\n\n (rest of output snipped)\n\nThe patch addresses this by changing bpf_refcount_acquire_impl to use\nrefcount_inc_not_zero instead of refcount_inc and marking\nbpf_refcount_acquire KF_RET_NULL.\n\nFor owning references, though, we know the above scenario is not possible\nand thus that bpf_refcount_acquire will always succeed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix wild-memory-access in register_synth_event()
In register_synth_event(), if set_synth_event_print_fmt() failed, then
both trace_remove_event_call() and unregister_trace_event() will be
called, which means the trace_event_call will call
__unregister_trace_event() twice. As the result, the second unregister
will causes the wild-memory-access.
register_synth_event
set_synth_event_print_fmt failed
trace_remove_event_call
event_remove
if call->event.funcs then
__unregister_trace_event (first call)
unregister_trace_event
__unregister_trace_event (second call)
Fix the bug by avoiding to call the second __unregister_trace_event() by
checking if the first one is called.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vdpa: Add features attr to vdpa_nl_policy for nlattr length check
The vdpa_nl_policy structure is used to validate the nlattr when parsing
the incoming nlmsg. It will ensure the attribute being described produces
a valid nlattr pointer in info->attrs before entering into each handler
in vdpa_nl_ops.
That is to say, the missing part in vdpa_nl_policy may lead to illegal
nlattr after parsing, which could lead to OOB read just like CVE-2023-3773.
This patch adds the missing nla_policy for vdpa features attr to avoid
such bugs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: fix potential OF node use-after-free
The for_each_child_of_node() helper drops the reference it takes to each
node as it iterates over children and an explicit of_node_put() is only
needed when exiting the loop early.
Drop the recently introduced bogus additional reference count decrement
at each iteration that could potentially lead to a use-after-free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
atm: atmtcp: Prevent arbitrary write in atmtcp_recv_control().
syzbot reported the splat below. [0]
When atmtcp_v_open() or atmtcp_v_close() is called via connect()
or close(), atmtcp_send_control() is called to send an in-kernel
special message.
The message has ATMTCP_HDR_MAGIC in atmtcp_control.hdr.length.
Also, a pointer of struct atm_vcc is set to atmtcp_control.vcc.
The notable thing is struct atmtcp_control is uAPI but has a
space for an in-kernel pointer.
struct atmtcp_control {
struct atmtcp_hdr hdr; /* must be first */
...
atm_kptr_t vcc; /* both directions */
...
} __ATM_API_ALIGN;
typedef struct { unsigned char _[8]; } __ATM_API_ALIGN atm_kptr_t;
The special message is processed in atmtcp_recv_control() called
from atmtcp_c_send().
atmtcp_c_send() is vcc->dev->ops->send() and called from 2 paths:
1. .ndo_start_xmit() (vcc->send() == atm_send_aal0())
2. vcc_sendmsg()
The problem is sendmsg() does not validate the message length and
userspace can abuse atmtcp_recv_control() to overwrite any kptr
by atmtcp_control.
Let's add a new ->pre_send() hook to validate messages from sendmsg().

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware_loader: Fix use-after-free during unregister
In the following code within firmware_upload_unregister(), the call to
device_unregister() could result in the dev_release function freeing the
fw_upload_priv structure before it is dereferenced for the call to
module_put(). This bug was found by the kernel test robot using
CONFIG_KASAN while running the firmware selftests.
device_unregister(&fw_sysfs->dev);
module_put(fw_upload_priv->module);
The problem is fixed by copying fw_upload_priv->module to a local variable
for use when calling device_unregister().

Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: sdhci-of-esdhc: Fix refcount leak in esdhc_signal_voltage_switch
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
of_node_put() checks null pointer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
pNFS: Fix uninited ptr deref in block/scsi layout
The error occurs on the third attempt to encode extents. When function
ext_tree_prepare_commit() reallocates a larger buffer to retry encoding
extents, the "layoutupdate_pages" page array is initialized only after the
retry loop. But ext_tree_free_commitdata() is called on every iteration
and tries to put pages in the array, thus dereferencing uninitialized
pointers.
An additional problem is that there is no limit on the maximum possible
buffer_size. When there are too many extents, the client may create a
layoutcommit that is larger than the maximum possible RPC size accepted
by the server.
During testing, we observed two typical scenarios. First, one memory page
for extents is enough when we work with small files, append data to the
end of the file, or preallocate extents before writing. But when we fill
a new large file without preallocating, the number of extents can be huge,
and counting the number of written extents in ext_tree_encode_commit()
does not help much. Since this number increases even more between
unlocking and locking of ext_tree, the reallocated buffer may not be
large enough again and again.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: check for station first in client probe
When probing a client, first check if we have it, and then
check for the channel context, otherwise you can trigger
the warning there easily by probing when the AP isn't even
started yet. Since a client existing means the AP is also
operating, we can then keep the warning.
Also simplify the moved code a bit.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: iforce - wake up after clearing IFORCE_XMIT_RUNNING flag
syzbot is reporting hung task at __input_unregister_device() [1], for
iforce_close() waiting at wait_event_interruptible() with dev->mutex held
is blocking input_disconnect_device() from __input_unregister_device().
It seems that the cause is simply that commit c2b27ef672992a20 ("Input:
iforce - wait for command completion when closing the device") forgot to
call wake_up() after clear_bit().
Fix this problem by introducing a helper that calls clear_bit() followed
by wake_up_all().

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Do not let histogram values have some modifiers
Histogram values can not be strings, stacktraces, graphs, symbols,
syscalls, or grouped in buckets or log. Give an error if a value is set to
do so.
Note, the histogram code was not prepared to handle these modifiers for
histograms and caused a bug.
Mark Rutland reported:
# echo 'p:copy_to_user __arch_copy_to_user n=$arg2' >> /sys/kernel/tracing/kprobe_events
# echo 'hist:keys=n:vals=hitcount.buckets=8:sort=hitcount' > /sys/kernel/tracing/events/kprobes/copy_to_user/trigger

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Avoid fcport pointer dereference
Klocwork reported warning of NULL pointer may be dereferenced. The routine
exits when sa_ctl is NULL and fcport is allocated after the exit call thus
causing NULL fcport pointer to dereference at the time of exit.
To avoid fcport pointer dereference, exit the routine when sa_ctl is NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/hfi1: fix potential memory leak in setup_base_ctxt()
setup_base_ctxt() allocates a memory chunk for uctxt->groups with
hfi1_alloc_ctxt_rcv_groups(). When init_user_ctxt() fails, uctxt->groups
is not released, which will lead to a memory leak.
We should release the uctxt->groups with hfi1_free_ctxt_rcv_groups()
when init_user_ctxt() fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: do not assert we found block group item when creating free space tree
Currently, when building a free space tree at populate_free_space_tree(),
if we are not using the block group tree feature, we always expect to find
block group items (either extent items or a block group item with key type
BTRFS_BLOCK_GROUP_ITEM_KEY) when we search the extent tree with
btrfs_search_slot_for_read(), so we assert that we found an item. However
this expectation is wrong since we can have a new block group created in
the current transaction which is still empty and for which we still have
not added the block group's item to the extent tree, in which case we do
not have any items in the extent tree associated to the block group.
The insertion of a new block group's block group item in the extent tree
happens at btrfs_create_pending_block_groups() when it calls the helper
insert_block_group_item(). This typically is done when a transaction
handle is released, committed or when running delayed refs (either as
part of a transaction commit or when serving tickets for space reservation
if we are low on free space).
So remove the assertion at populate_free_space_tree() even when the block
group tree feature is not enabled and update the comment to mention this
case.
Syzbot reported this with the following stack trace:
BTRFS info (device loop3 state M): rebuilding free space tree

corresponding resource. However, the trace_array in gen_kretprobe_test
will point to the invalid resource. Set gen_kretprobe_test to NULL
after called kprobe_event_delete() to prevent null-ptr-deref.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix BUG_ON condition in btrfs_cancel_balance
Pausing and canceling balance can race to interrupt balance lead to BUG_ON
panic in btrfs_cancel_balance. The BUG_ON condition in btrfs_cancel_balance
does not take this race scenario into account.
However, the race condition has no other side effects. We can fix that.
Reproducing it with panic trace like this:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipvs: fix WARNING in ip_vs_app_net_cleanup()
During the initialization of ip_vs_app_net_init(), if file ip_vs_app
fails to be created, the initialization is successful by default.
Therefore, the ip_vs_app file doesn't be found during the remove in
ip_vs_app_net_cleanup(). It will cause WRNING.
The following is the stack information:

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: az6007: Fix null-ptr-deref in az6007_i2c_xfer()
In az6007_i2c_xfer, msg is controlled by user. When msg[i].buf
is null and msg[i].len is zero, former checks on msg[i].buf would be
passed. Malicious data finally reach az6007_i2c_xfer. If accessing
msg[i].buf[0] without sanity check, null ptr deref would happen.
We add check on msg[i].len to prevent crash.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: usbtv: Lock resolution while streaming
When an program is streaming (ffplay) and another program (qv4l2)
changes the TV standard from NTSC to PAL, the kernel crashes due to trying
to copy to unmapped memory.
Changing from NTSC to PAL increases the resolution in the usbtv struct,
but the video plane buffer isn't adjusted, so it overflows.
[hverkuil: call vb2_is_busy instead of vb2_is_streaming]

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-cgroup: properly pin the parent in blkcg_css_online
blkcg_css_online is supposed to pin the blkcg of the parent, but
397c9f46ee4d refactored things and along the way, changed it to pin the
css instead. This results in extra pins, and we end up leaking blkcgs
and cgroups.

Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/hfi1: Correctly move list in sc_disable()
Commit 13bac861952a ("IB/hfi1: Fix abba locking issue with sc_disable()")
incorrectly tries to move a list from one list head to another. The
result is a kernel crash.
The crash is triggered when a link goes down and there are waiters for a
send to complete. The following signature is seen:
BUG: kernel NULL pointer dereference, address: 0000000000000030
[...]
Call Trace:
sc_disable+0x1ba/0x240 [hfi1]

The fix is to use the correct call to move the list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: hfsc: Fix a UAF vulnerability in class with netem as child qdisc
As described in Gerrard's report [1], we have a UAF case when an hfsc class
has a netem child qdisc. The crux of the issue is that hfsc is assuming
that checking for cl->qdisc->q.qlen == 0 guarantees that it hasn't inserted
the class in the vttree or eltree (which is not true for the netem
duplicate case).
This patch checks the n_active class variable to make sure that the code
won't insert the class in the vttree or eltree twice, catering for the
reentrant case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: qcom: bam_dma: Fix DT error handling for num-channels/ees
When we don't have a clock specified in the device tree, we have no way to
ensure the BAM is on. This is often the case for remotely-controlled or
remotely-powered BAM instances. In this case, we need to read num-channels
from the DT to have all the necessary information to complete probing.
However, at the moment invalid device trees without clock and without
num-channels still continue probing, because the error handling is missing
return statements. The driver will then later try to read the number of
channels from the registers. This is unsafe, because it relies on boot
firmware and lucky timing to succeed. Unfortunately, the lack of proper
error handling here has been abused for several Qualcomm SoCs upstream,
causing early boot crashes in several situations [1, 2].
Avoid these early crashes by erroring out when any of the required DT
properties are missing. Note that this will break some of the existing DTs
upstream (mainly BAM instances related to the crypto engine). However,
clearly these DTs have never been tested properly, since the error in the
kernel log was just ignored. It's safer to disable the crypto engine for
these broken DTBs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau/disp: fix use-after-free in error handling of nouveau_connector_create
We can't simply free the connector after calling drm_connector_init on it.
We need to clean up the drm side first.
It might not fix all regressions from commit 2b5d1c29f6c4
("drm/nouveau/disp: PIOR DP uses GPIO for HPD, not PMGR AUX interrupts"),
but at least it fixes a memory corruption in error handling related to
that commit.

Summary
In the Linux kernel, the following vulnerability has been resolved:
video: fbdev: s3fb: Check the size of screen before memset_io()
In the function s3fb_set_par(), the value of 'screen_size' is
calculated by the user input. If the user provides the improper value,
the value of 'screen_size' may larger than 'info->screen_size', which
may cause the following bug:
[ 54.083733] BUG: unable to handle page fault for address: ffffc90003000000
[ 54.083742] #PF: supervisor write access in kernel mode
[ 54.083744] #PF: error_code(0x0002) - not-present page
[ 54.083760] RIP: 0010:memset_orig+0x33/0xb0
[ 54.083782] Call Trace:
[ 54.083788] s3fb_set_par+0x1ec6/0x4040
[ 54.083806] fb_set_var+0x604/0xeb0
[ 54.083836] do_fb_ioctl+0x234/0x670
Fix the this by checking the value of 'screen_size' before memset_io().

Summary
In the Linux kernel, the following vulnerability has been resolved:
apparmor: fix reference count leak in aa_pivotroot()
The aa_pivotroot() function has a reference counting bug in a specific
path. When aa_replace_current_label() returns on success, the function
forgets to decrement the reference count of “target”, which is
increased earlier by build_pivotroot(), causing a reference leak.
Fix it by decreasing the refcount of “target” in that path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vxlan: Fix nexthop hash size
The nexthop code expects a 31 bit hash, such as what is returned by
fib_multipath_hash() and rt6_multipath_hash(). Passing the 32 bit hash
returned by skb_get_hash() can lead to problems related to the fact that
'int hash' is a negative number when the MSB is set.
In the case of hash threshold nexthop groups, nexthop_select_path_hthr()
will disproportionately select the first nexthop group entry. In the case
of resilient nexthop groups, nexthop_select_path_res() may do an out of
bounds access in nh_buckets[], for example:
hash = -912054133
num_nh_buckets = 2
bucket_index = 65535
which leads to the following panic:

Summary
In the Linux kernel, the following vulnerability has been resolved:
pfifo_tail_enqueue: Drop new packet when sch->limit == 0
Expected behaviour:
In case we reach scheduler's limit, pfifo_tail_enqueue() will drop a
packet in scheduler's queue and decrease scheduler's qlen by one.
Then, pfifo_tail_enqueue() enqueue new packet and increase
scheduler's qlen by one. Finally, pfifo_tail_enqueue() return
`NET_XMIT_CN` status code.
Weird behaviour:
In case we set `sch->limit == 0` and trigger pfifo_tail_enqueue() on a
scheduler that has no packet, the 'drop a packet' step will do nothing.
This means the scheduler's qlen still has value equal 0.
Then, we continue to enqueue new packet and increase scheduler's qlen by
one. In summary, we can leverage pfifo_tail_enqueue() to increase qlen by
one and return `NET_XMIT_CN` status code.
The problem is:
Let's say we have two qdiscs: Qdisc_A and Qdisc_B.
- Qdisc_A's type must have '->graft()' function to create parent/child relationship.
Let's say Qdisc_A's type is `hfsc`. Enqueue packet to this qdisc will trigger `hfsc_enqueue`.
- Qdisc_B's type is pfifo_head_drop. Enqueue packet to this qdisc will trigger `pfifo_tail_enqueue`.
- Qdisc_B is configured to have `sch->limit == 0`.
- Qdisc_A is configured to route the enqueued's packet to Qdisc_B.
Enqueue packet through Qdisc_A will lead to:
- hfsc_enqueue(Qdisc_A) -> pfifo_tail_enqueue(Qdisc_B)
- Qdisc_B->q.qlen += 1
- pfifo_tail_enqueue() return `NET_XMIT_CN`
- hfsc_enqueue() check for `NET_XMIT_SUCCESS` and see `NET_XMIT_CN` => hfsc_enqueue() don't increase qlen of Qdisc_A.
The whole process lead to a situation where Qdisc_A->q.qlen == 0 and Qdisc_B->q.qlen == 1.
Replace 'hfsc' with other type (for example: 'drr') still lead to the same problem.
This violate the design where parent's qlen should equal to the sum of its childrens'qlen.
Bug impact: This issue can be used for user->kernel privilege escalation when it is reachable.

Finally, pfifo_tail_enqueue() return\n`NET_XMIT_CN` status code.\n\nWeird behaviour:\nIn case we set `sch-\u003elimit == 0` and trigger pfifo_tail_enqueue() on a\nscheduler that has no packet, the \u0027drop a packet\u0027 step will do nothing.\nThis means the scheduler\u0027s qlen still has value equal 0.\nThen, we continue to enqueue new packet and increase scheduler\u0027s qlen by\none. In summary, we can leverage pfifo_tail_enqueue() to increase qlen by\none and return `NET_XMIT_CN` status code.\n\nThe problem is:\nLet\u0027s say we have two qdiscs: Qdisc_A and Qdisc_B.\n - Qdisc_A\u0027s type must have \u0027-\u003egraft()\u0027 function to create parent/child relationship.\n Let\u0027s say Qdisc_A\u0027s type is `hfsc`. Enqueue packet to this qdisc will trigger `hfsc_enqueue`.\n - Qdisc_B\u0027s type is pfifo_head_drop. Enqueue packet to this qdisc will trigger `pfifo_tail_enqueue`.\n - Qdisc_B is configured to have `sch-\u003elimit == 0`.\n - Qdisc_A is configured to route the enqueued\u0027s packet to Qdisc_B.\n\nEnqueue packet through Qdisc_A will lead to:\n - hfsc_enqueue(Qdisc_A) -\u003e pfifo_tail_enqueue(Qdisc_B)\n - Qdisc_B-\u003eq.qlen += 1\n - pfifo_tail_enqueue() return `NET_XMIT_CN`\n - hfsc_enqueue() check for `NET_XMIT_SUCCESS` and see `NET_XMIT_CN` =\u003e hfsc_enqueue() don\u0027t increase qlen of Qdisc_A.\n\nThe whole process lead to a situation where Qdisc_A-\u003eq.qlen == 0 and Qdisc_B-\u003eq.qlen == 1.\nReplace \u0027hfsc\u0027 with other type (for example: \u0027drr\u0027) still lead to the same problem.\nThis violate the design where parent\u0027s qlen should equal to the sum of its childrens\u0027qlen.\n\nBug impact: This issue can be used for user-\u003ekernel privilege escalation when it is reachable."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ata: libata-transport: fix double ata_host_put() in ata_tport_add()
In the error path in ata_tport_add(), when calling put_device(),
ata_tport_release() is called, it will put the refcount of 'ap->host'.
And then ata_host_put() is called again, the refcount is decreased
to 0, ata_host_release() is called, all ports are freed and set to
null.
When unbinding the device after failure, ata_host_stop() is called
to release the resources, it leads a null-ptr-deref(), because all
the ports all freed and null.
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/page_alloc: fix race condition in unaccepted memory handling
The page allocator tracks the number of zones that have unaccepted memory
using static_branch_enc/dec() and uses that static branch in hot paths to
determine if it needs to deal with unaccepted memory.
Borislav and Thomas pointed out that the tracking is racy: operations on
static_branch are not serialized against adding/removing unaccepted pages
to/from the zone.
Sanity checks inside static_branch machinery detects it:
WARNING: CPU: 0 PID: 10 at kernel/jump_label.c:276 __static_key_slow_dec_cpuslocked+0x8e/0xa0
The comment around the WARN() explains the problem:
/*
* Warn about the '-1' case though; since that means a
* decrement is concurrent with a first (0->1) increment. IOW
* people are trying to disable something that wasn't yet fully
* enabled. This suggests an ordering problem on the user side.
*/
The effect of this static_branch optimization is only visible on
microbenchmark.
Instead of adding more complexity around it, remove it altogether.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: cros_ec_codec: Fix refcount leak in cros_ec_codec_platform_probe
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: fb_pm2fb: Avoid potential divide by zero error
In `do_fb_ioctl()` of fbmem.c, if cmd is FBIOPUT_VSCREENINFO, var will be
copied from user, then go through `fb_set_var()` and
`info->fbops->fb_check_var()` which could may be `pm2fb_check_var()`.
Along the path, `var->pixclock` won't be modified. This function checks
whether reciprocal of `var->pixclock` is too high. If `var->pixclock` is
zero, there will be a divide by zero error. So, it is necessary to check
whether denominator is zero to avoid crash. As this bug is found by
Syzkaller, logs are listed below.
divide error in pm2fb_check_var

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix memory leak in WMI firmware stats
Memory allocated for firmware pdev, vdev and beacon statistics
are not released during rmmod.
Fix it by calling ath11k_fw_stats_free() function before hardware
unregister.
While at it, avoid calling ath11k_fw_stats_free() while processing
the firmware stats received in the WMI event because the local list
is getting spliced and reinitialised and hence there are no elements
in the list after splicing.
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: host: Fix refcount leak in ehci_hcd_ppc_of_probe
of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: nl80211: fix integer overflow in nl80211_parse_mbssid_elems()
nl80211_parse_mbssid_elems() uses a u8 variable num_elems to count the
number of MBSSID elements in the nested netlink attribute attrs, which can
lead to an integer overflow if a user of the nl80211 interface specifies
256 or more elements in the corresponding attribute in userspace. The
integer overflow can lead to a heap buffer overflow as num_elems determines
the size of the trailing array in elems, and this array is thereafter
written to for each element in attrs.
Note that this vulnerability only affects devices with the
wiphy->mbssid_max_interfaces member set for the wireless physical device
struct in the device driver, and can only be triggered by a process with
CAP_NET_ADMIN capabilities.
Fix this by checking for a maximum of 255 elements in attrs.

Per kernel scoring guidance, netlink-reachable bugs are Local.\nAC:L - The attacker fully and deterministically controls the trigger by placing 256 nested attributes in NL80211_ATTR_MBSSID_ELEMS \u2014 no race, no timing, no memory-layout condition outside their influence, and the overflow size and contents are directly tunable via the attribute count and lengths.\nPR:L - The gate is GENL_UNS_ADMIN_PERM, i.e. netlink_ns_capable(net-\u003euser_ns, CAP_NET_ADMIN), which an unprivileged user obtains via `unshare -Urn`; mac80211_hwsim\u0027s radio-creation command is gated identically and places the new wiphy (with mbssid_max_interfaces = 8) in the caller\u0027s netns, giving a complete unprivileged local path.\nUI:N - The attacker performs every step themselves \u2014 create/select an AP-capable interface and issue the netlink command \u2014 with no action required from any other user or administrator.\nS:U - The heap corruption occurs in kernel slab memory within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - A 4 KB controlled out-of-bounds heap write lets the attacker overwrite adjacent objects\u0027 pointers and length fields, which is readily leveraged into arbitrary kernel-memory disclosure, so confidentiality impact is High.\nI:H - This is a large, attacker-sized out-of-bounds heap write with a fully attacker-controlled size_t field per entry, providing a strong slab-corruption primitive suitable for control-flow hijack and privilege escalation.\nA:H - Writing 4096 bytes past an 8-byte kmalloc allocation reliably corrupts slab metadata and neighbouring objects, producing kernel oops/panic and complete loss of availability."
