Summary
In the Linux kernel, the following vulnerability has been resolved:
md/raid5: avoid BUG_ON() while continue reshape after reassembling
Currently, mdadm support --revert-reshape to abort the reshape while
reassembling, as the test 07revert-grow. However, following BUG_ON()
can be triggerred by the test:
kernel BUG at drivers/md/raid5.c:6278!
invalid opcode: 0000 [#1] PREEMPT SMP PTI
irq event stamp: 158985
CPU: 6 PID: 891 Comm: md0_reshape Not tainted 6.9.0-03335-g7592a0b0049a #94
RIP: 0010:reshape_request+0x3f1/0xe60
Call Trace:
<TASK>
raid5_sync_request+0x43d/0x550
md_do_sync+0xb7a/0x2110
md_thread+0x294/0x2b0
kthread+0x147/0x1c0
ret_from_fork+0x59/0x70
ret_from_fork_asm+0x1a/0x30
</TASK>
Root cause is that --revert-reshape update the raid_disks from 5 to 4,
while reshape position is still set, and after reassembling the array,
reshape position will be read from super block, then during reshape the
checking of 'writepos' that is caculated by old reshape position will
fail.
Fix this panic the easy way first, by converting the BUG_ON() to
WARN_ON(), and stop the reshape if checkings fail.
Noted that mdadm must fix --revert-shape as well, and probably md/raid
should enhance metadata validation as well, however this means
reassemble will fail and there must be user tools to fix the wrong
metadata.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix inode number range checks
Patch series "nilfs2: fix potential issues related to reserved inodes".
This series fixes one use-after-free issue reported by syzbot, caused by
nilfs2's internal inode being exposed in the namespace on a corrupted
filesystem, and a couple of flaws that cause problems if the starting
number of non-reserved inodes written in the on-disk super block is
intentionally (or corruptly) changed from its default value.
This patch (of 3):
In the current implementation of nilfs2, "nilfs->ns_first_ino", which
gives the first non-reserved inode number, is read from the superblock,
but its lower limit is not checked.
As a result, if a number that overlaps with the inode number range of
reserved inodes such as the root directory or metadata files is set in the
super block parameter, the inode number test macros (NILFS_MDT_INODE and
NILFS_VALID_INODE) will not function properly.
In addition, these test macros use left bit-shift calculations using with
the inode number as the shift count via the BIT macro, but the result of a
shift calculation that exceeds the bit width of an integer is undefined in
the C specification, so if "ns_first_ino" is set to a large value other
than the default value NILFS_USER_INO (=11), the macros may potentially
malfunction depending on the environment.
Fix these issues by checking the lower bound of "nilfs->ns_first_ino" and
by preventing bit shifts equal to or greater than the NILFS_USER_INO
constant in the inode number test macros.
Also, change the type of "ns_first_ino" from signed integer to unsigned
integer to avoid the need for type casting in comparisons such as the
lower bound check introduced this time.

The reproducer invokes shutdown() before entering the listener status.
After commit 94062790aedb ("tcp: defer shutdown(SEND_SHUTDOWN) for
TCP_SYN_RECV sockets"), the above causes the child to reach the accept
syscall in FIN_WAIT1 status.
Eric noted we can relax the existing assertion in __inet_accept()

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs: don't misleadingly warn during thaw operations
The block device may have been frozen before it was claimed by a
filesystem. Concurrently another process might try to mount that
frozen block device and has temporarily claimed the block device for
that purpose causing a concurrent fs_bdev_thaw() to end up here. The
mounter is already about to abort mounting because they still saw an
elevanted bdev->bd_fsfreeze_count so get_bdev_super() will return
NULL in that case.
For example, P1 calls dm_suspend() which calls into bdev_freeze() before
the block device has been claimed by the filesystem. This brings
bdev->bd_fsfreeze_count to 1 and no call into fs_bdev_freeze() is
required.
Now P2 tries to mount that frozen block device. It claims it and checks
bdev->bd_fsfreeze_count. As it's elevated it aborts mounting.
In the meantime P3 called dm_resume(). P3 sees that the block device is
already claimed by a filesystem and calls into fs_bdev_thaw().
P3 takes a passive reference and realizes that the filesystem isn't
ready yet. P3 puts itself to sleep to wait for the filesystem to become
ready.
P2 now puts the last active reference to the filesystem and marks it as
dying. P3 gets woken, sees that the filesystem is dying and
get_bdev_super() fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
kobject_uevent: Fix OOB access within zap_modalias_env()
zap_modalias_env() wrongly calculates size of memory block to move, so
will cause OOB memory access issue if variable MODALIAS is not the last
one within its @env parameter, fixed by correcting size to memmove.

Metadata added by bio_integrity_prep is using plain kmalloc, which leads
to random kernel memory being written media. For PI metadata this is
limited to the app tag that isn't used by kernel generated metadata,
but for non-PI metadata the entire buffer leaks kernel memory.
Fix this by adding the __GFP_ZERO flag to allocations for writes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
protect the fetch of ->fd[fd] in do_dup2() from mispredictions
both callers have verified that fd is not greater than ->max_fds;
however, misprediction might end up with
tofree = fdt->fd[fd];
being speculatively executed. That's wrong for the same reasons
why it's wrong in close_fd()/file_close_fd_locked(); the same
solution applies - array_index_nospec(fd, fdt->max_fds) could differ
from fd only in case of speculative execution on mispredicted path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
riscv: kexec: Avoid deadlock in kexec crash path
If the kexec crash code is called in the interrupt context, the
machine_kexec_mask_interrupts() function will trigger a deadlock while
trying to acquire the irqdesc spinlock and then deactivate irqchip in
irq_set_irqchip_state() function.
Unlike arm64, riscv only requires irq_eoi handler to complete EOI and
keeping irq_set_irqchip_state() will only leave this possible deadlock
without any use. So we simply remove it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: serial: mos7840: fix crash on resume
Since commit c49cfa917025 ("USB: serial: use generic method if no
alternative is provided in usb serial layer"), USB serial core calls the
generic resume implementation when the driver has not provided one.
This can trigger a crash on resume with mos7840 since support for
multiple read URBs was added back in 2011. Specifically, both port read
URBs are now submitted on resume for open ports, but the context pointer
of the second URB is left set to the core rather than mos7840 port
structure.
Fix this by implementing dedicated suspend and resume functions for
mos7840.
Tested with Delock 87414 USB 2.0 to 4x serial adapter.
[ johan: analyse crash and rewrite commit message; set busy flag on
resume; drop bulk-in check; drop unnecessary usb_kill_urb() ]

Summary
In the Linux kernel, the following vulnerability has been resolved:
ftruncate: pass a signed offset
The old ftruncate() syscall, using the 32-bit off_t misses a sign
extension when called in compat mode on 64-bit architectures. As a
result, passing a negative length accidentally succeeds in truncating
to file size between 2GiB and 4GiB.
Changing the type of the compat syscall to the signed compat_off_t
changes the behavior so it instead returns -EINVAL.
The native entry point, the truncate() syscall and the corresponding
loff_t based variants are all correct already and do not suffer
from this mistake.

Summary
In the Linux kernel, the following vulnerability has been resolved:
filelock: Fix fcntl/close race recovery compat path
When I wrote commit 3cad1bc01041 ("filelock: Remove locks reliably when
fcntl/close race is detected"), I missed that there are two copies of the
code I was patching: The normal version, and the version for 64-bit offsets
on 32-bit kernels.
Thanks to Greg KH for stumbling over this while doing the stable
backport...
Apply exactly the same fix to the compat path for 32-bit kernels.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: line6: Fix racy access to midibuf
There can be concurrent accesses to line6 midibuf from both the URB
completion callback and the rawmidi API access. This could be a cause
of KMSAN warning triggered by syzkaller below (so put as reported-by
here).
This patch protects the midibuf call of the former code path with a
spinlock for avoiding the possible races.

"value": "AV:L - The unsynchronized accesses are in `line6_data_received()` (URB completion for the control/MIDI-in endpoint) racing the rawmidi API path, and the driver is only bound when a Line 6 device is already attached \u2014 so a local unprivileged user on such a host drives both halves via `/dev/snd/midiC*D*` (and the hwdep node), writing MIDI/sysex to solicit device replies that generate URB completions while concurrently hammering rawmidi read/trigger. No physical access by the attacker is needed in that deployment (audio workstation, live-performance rig).\nAC:L - The attacker controls both sides of the race \u2014 one thread issues rawmidi/hwdep writes that make the device respond on the interrupt-in endpoint, another thread concurrently exercises the rawmidi API \u2014 and the window can be retried indefinitely at MIDI packet rate. Per the guidance, a race whose both sides the attacker creates is Low.\nPR:L - Only ordinary access to the ALSA rawmidi/hwdep character devices is required, which the console/desktop user gets by default through udev ACLs or `audio` group membership. No CAP_SYS_ADMIN or root is needed.\nUI:N - The attacker performs every step itself \u2014 opening the rawmidi node, soliciting device traffic, and racing the accesses. Presence of the Line 6 device is a property of the affected system (the driver does not load otherwise), not a victim action during the attack.\nS:U - The corrupted ring-buffer state, the heap over-read, and the disclosed data all live in the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - syzbot confirmed \"KMSAN: uninit-value in line6_midibuf_read\" at `midibuf.c:185` \u2014 racy `pos_read`/`pos_write`/`full` make the reader consume bytes never written, so stale contents of the `kmalloc()`ed 1024-byte `midi_buffer.buf` slab object are memcpy\u0027d into `line6-\u003ebuffer_message` and delivered to userspace through `snd_rawmidi_receive()`. A stale `length1 = size - pos_write`/`pos_read` pair also lets the copy index past the end of that allocation, and the leak is repeatable, allowing kernel heap contents (pointers, recycled data) to be harvested.\nI:H - `line6_midibuf_write()` computes `length1 = this-\u003esize - this-\u003epos_write` and then does `memcpy(this-\u003ebuf + this-\u003epos_write, data, length1)` re-reading `pos_write`; with no lock, a concurrent index update makes that copy run past the end of the kmalloc-1024 object with device-supplied MIDI bytes, giving an attacker-influenced heap out-of-bounds write, and corrupted indices also feed bogus data into the rawmidi stream.\nA:H - Out-of-bounds reads and writes on the kmalloc-1024 slab object corrupt adjacent allocations and trip sanitizer/hardening checks, producing oops or panic. The bug is a memory-safety error, which per the guidance is High availability impact."

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfc: pn533: Add poll mod list filling check
In case of im_protocols value is 1 and tm_protocols value is 0 this
combination successfully passes the check
'if (!im_protocols && !tm_protocols)' in the nfc_start_poll().
But then after pn533_poll_create_mod_list() call in pn533_start_poll()
poll mod list will remain empty and dev->poll_mod_count will remain 0
which lead to division by zero.
Normally no im protocol has value 1 in the mask, so this combination is
not expected by driver. But these protocol values actually come from
userspace via Netlink interface (NFC_CMD_START_POLL operation). So a
broken or malicious program may pass a message containing a "bad"
combination of protocol parameter values so that dev->poll_mod_count
is not incremented inside pn533_poll_create_mod_list(), thus leading
to division by zero.
Call trace looks like:
nfc_genl_start_poll()
nfc_start_poll()
->start_poll()
pn533_start_poll()
Add poll mod list filling check.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: topology: Fix references to freed memory
Most users after parsing a topology file, release memory used by it, so
having pointer references directly into topology file contents is wrong.
Use devm_kmemdup(), to allocate memory as needed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-fabrics: use reserved tag for reg read/write command
In some scenarios, if too many commands are issued by nvme command in
the same time by user tasks, this may exhaust all tags of admin_q. If
a reset (nvme reset or IO timeout) occurs before these commands finish,
reconnect routine may fail to update nvme regs due to insufficient tags,
which will cause kernel hang forever. In order to workaround this issue,
maybe we can let reg_read32()/reg_read64()/reg_write32() use reserved
tags. This maybe safe for nvmf:
1. For the disable ctrl path, we will not issue connect command
2. For the enable ctrl / fw activate path, since connect and reg_xx()
are called serially.
So the reserved tags may still be enough while reg_xx() use reserved tags.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: core: remove lock of otg mode during gadget suspend/resume to avoid deadlock
When config CONFIG_USB_DWC3_DUAL_ROLE is selected, and trigger system
to enter suspend status with below command:
echo mem > /sys/power/state
There will be a deadlock issue occurring. Detailed invoking path as
below:
dwc3_suspend_common()
spin_lock_irqsave(&dwc->lock, flags); <-- 1st
dwc3_gadget_suspend(dwc);
dwc3_gadget_soft_disconnect(dwc);
spin_lock_irqsave(&dwc->lock, flags); <-- 2nd
This issue is exposed by commit c7ebd8149ee5 ("usb: dwc3: gadget: Fix
NULL pointer dereference in dwc3_gadget_suspend") that removes the code
of checking whether dwc->gadget_driver is NULL or not. It causes the
following code is executed and deadlock occurs when trying to get the
spinlock. In fact, the root cause is the commit 5265397f9442("usb: dwc3:
Remove DWC3 locking during gadget suspend/resume") that forgot to remove
the lock of otg mode. So, remove the redundant lock of otg mode during
gadget suspend/resume.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: flower: Fix chain template offload
When a qdisc is deleted from a net device the stack instructs the
underlying driver to remove its flow offload callback from the
associated filter block using the 'FLOW_BLOCK_UNBIND' command. The stack
then continues to replay the removal of the filters in the block for
this driver by iterating over the chains in the block and invoking the
'reoffload' operation of the classifier being used. In turn, the
classifier in its 'reoffload' operation prepares and emits a
'FLOW_CLS_DESTROY' command for each filter.
However, the stack does not do the same for chain templates and the
underlying driver never receives a 'FLOW_CLS_TMPLT_DESTROY' command when
a qdisc is deleted. This results in a memory leak [1] which can be
reproduced using [2].
Fix by introducing a 'tmplt_reoffload' operation and have the stack
invoke it with the appropriate arguments as part of the replay.
Implement the operation in the sole classifier that supports chain
templates (flower) by emitting the 'FLOW_CLS_TMPLT_{CREATE,DESTROY}'
command based on whether a flow offload callback is being bound to a
filter block or being unbound from one.
As far as I can tell, the issue happens since cited commit which
reordered tcf_block_offload_unbind() before tcf_block_flush_all_chains()
in __tcf_block_put(). The order cannot be reversed as the filter block
is expected to be freed after flushing all the chains.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sched: flower: Fix chain template offload\n\nWhen a qdisc is deleted from a net device the stack instructs the\nunderlying driver to remove its flow offload callback from the\nassociated filter block using the \u0027FLOW_BLOCK_UNBIND\u0027 command. The stack\nthen continues to replay the removal of the filters in the block for\nthis driver by iterating over the chains in the block and invoking the\n\u0027reoffload\u0027 operation of the classifier being used. In turn, the\nclassifier in its \u0027reoffload\u0027 operation prepares and emits a\n\u0027FLOW_CLS_DESTROY\u0027 command for each filter.\n\nHowever, the stack does not do the same for chain templates and the\nunderlying driver never receives a \u0027FLOW_CLS_TMPLT_DESTROY\u0027 command when\na qdisc is deleted. This results in a memory leak [1] which can be\nreproduced using [2].\n\nFix by introducing a \u0027tmplt_reoffload\u0027 operation and have the stack\ninvoke it with the appropriate arguments as part of the replay.\nImplement the operation in the sole classifier that supports chain\ntemplates (flower) by emitting the \u0027FLOW_CLS_TMPLT_{CREATE,DESTROY}\u0027\ncommand based on whether a flow offload callback is being bound to a\nfilter block or being unbound from one.\n\nAs far as I can tell, the issue happens since cited commit which\nreordered tcf_block_offload_unbind() before tcf_block_flush_all_chains()\nin __tcf_block_put(). The order cannot be reversed as the filter block\nis expected to be freed after flushing all the chains.\n\n[1]\nunreferenced object 0xffff888107e28800 (size 2048):\n comm \"tc\", pid 1079, jiffies 4294958525 (age 3074.287s)\n hex dump (first 32 bytes):\n b1 a6 7c 11 81 88 ff ff e0 5b b3 10 81 88 ff ff ..|......[......\n 01 00 00 00 00 00 00 00 e0 aa b0 84 ff ff ff ff ................\n backtrace:\n [\u003cffffffff81c06a68\u003e] __kmem_cache_alloc_node+0x1e8/0x320\n [\u003cffffffff81ab374e\u003e] __kmalloc+0x4e/0x90\n [\u003cffffffff832aec6d\u003e] mlxsw_sp_acl_ruleset_get+0x34d/0x7a0\n [\u003cffffffff832bc195\u003e] mlxsw_sp_flower_tmplt_create+0x145/0x180\n [\u003cffffffff832b2e1a\u003e] mlxsw_sp_flow_block_cb+0x1ea/0x280\n [\u003cffffffff83a10613\u003e] tc_setup_cb_call+0x183/0x340\n [\u003cffffffff83a9f85a\u003e] fl_tmplt_create+0x3da/0x4c0\n [\u003cffffffff83a22435\u003e] tc_ctl_chain+0xa15/0x1170\n [\u003cffffffff838a863c\u003e] rtnetlink_rcv_msg+0x3cc/0xed0\n [\u003cffffffff83ac87f0\u003e] netlink_rcv_skb+0x170/0x440\n [\u003cffffffff83ac6270\u003e] netlink_unicast+0x540/0x820\n [\u003cffffffff83ac6e28\u003e] netlink_sendmsg+0x8d8/0xda0\n [\u003cffffffff83793def\u003e] ____sys_sendmsg+0x30f/0xa80\n [\u003cffffffff8379d29a\u003e] ___sys_sendmsg+0x13a/0x1e0\n [\u003cffffffff8379d50c\u003e] __sys_sendmsg+0x11c/0x1f0\n [\u003cffffffff843b9ce0\u003e] do_syscall_64+0x40/0xe0\nunreferenced object 0xffff88816d2c0400 (size 1024):\n comm \"tc\", pid 1079, jiffies 4294958525 (age 3074.287s)\n hex dump (first 32 bytes):\n 40 00 00 00 00 00 00 00 57 f6 38 be 00 00 00 00 @.......W.8.....\n 10 04 2c 6d 81 88 ff ff 10 04 2c 6d 81 88 ff ff ..,m......,m....\n backtrace:\n [\u003cffffffff81c06a68\u003e] __kmem_cache_alloc_node+0x1e8/0x320\n [\u003cffffffff81ab36c1\u003e] __kmalloc_node+0x51/0x90\n [\u003cffffffff81a8ed96\u003e] kvmalloc_node+0xa6/0x1f0\n [\u003cffffffff82827d03\u003e] bucket_table_alloc.isra.0+0x83/0x460\n [\u003cffffffff82828d2b\u003e] rhashtable_init+0x43b/0x7c0\n [\u003cffffffff832aed48\u003e] mlxsw_sp_acl_ruleset_get+0x428/0x7a0\n [\u003cffffffff832bc195\u003e] mlxsw_sp_flower_tmplt_create+0x145/0x180\n [\u003cffffffff832b2e1a\u003e] mlxsw_sp_flow_block_cb+0x1ea/0x280\n [\u003cffffffff83a10613\u003e] tc_setup_cb_call+0x183/0x340\n [\u003cffffffff83a9f85a\u003e] fl_tmplt_create+0x3da/0x4c0\n [\u003cffffffff83a22435\u003e] tc_ctl_chain+0xa15/0x1170\n [\u003cffffffff838a863c\u003e] rtnetlink_rcv_msg+0x3cc/0xed0\n [\u003cffffffff83ac87f0\u003e] netlink_rcv_skb+0x170/0x440\n [\u003cffffffff83ac6270\u003e] netlink_unicast+0x540/0x820\n [\u003cffffffff83ac6e28\u003e] netlink_sendmsg+0x8d8/0xda0\n [\u003cffffffff83793def\u003e] ____sys_sendmsg+0x30f/0xa80\n\n[2]\n # tc qdisc add dev swp1 clsact\n # tc chain add dev swp1 ingress proto ip chain 1 flower dst_ip 0.0.0.0/32\n # tc qdisc del dev\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/mm: Fix VM_FAULT_HWPOISON handling in do_exception()
There is no support for HWPOISON, MEMORY_FAILURE, or ARCH_HAS_COPY_MC on
s390. Therefore we do not expect to see VM_FAULT_HWPOISON in
do_exception().
However, since commit af19487f00f3 ("mm: make PTE_MARKER_SWAPIN_ERROR more
general"), it is possible to see VM_FAULT_HWPOISON in combination with
PTE_MARKER_POISONED, even on architectures that do not support HWPOISON
otherwise. In this case, we will end up on the BUG() in do_exception().
Fix this by treating VM_FAULT_HWPOISON the same as VM_FAULT_SIGBUS, similar
to x86 when MEMORY_FAILURE is not configured. Also print unexpected fault
flags, for easier debugging.
Note that VM_FAULT_HWPOISON_LARGE is not expected, because s390 cannot
support swap entries on other levels than PTE level.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vhost_task: Handle SIGKILL by flushing work and exiting
Instead of lingering until the device is closed, this has us handle
SIGKILL by:
1. marking the worker as killed so we no longer try to use it with
new virtqueues and new flush operations.
2. setting the virtqueue to worker mapping so no new works are queued.
3. running all the exiting works.

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/sclp: Fix sclp_init() cleanup on failure
If sclp_init() fails it only partially cleans up: if there are multiple
failing calls to sclp_init() sclp_state_change_event will be added several
times to sclp_reg_list, which results in the following warning:
------------[ cut here ]------------

Fix this by removing sclp_state_change_event from sclp_reg_list when
sclp_init() fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mwifiex: Do not return unused priv in mwifiex_get_priv_by_id()
mwifiex_get_priv_by_id() returns the priv pointer corresponding to
the bss_num and bss_type, but without checking if the priv is actually
currently in use.
Unused priv pointers do not have a wiphy attached to them which can
lead to NULL pointer dereferences further down the callstack. Fix
this by returning only used priv pointers which have priv->bss_mode
set to something else than NL80211_IFTYPE_UNSPECIFIED.
Said NULL pointer dereference happened when an Accesspoint was started
with wpa_supplicant -i mlan0 with this config:
network={
ssid="somessid"
mode=2
frequency=2412
key_mgmt=WPA-PSK WPA-PSK-SHA256
proto=RSN
group=CCMP
pairwise=CCMP
psk="12345678"
}
When waiting for the AP to be established, interrupting wpa_supplicant
with <ctrl-c> and starting it again this happens:

This matches the adjacent-network treatment used for other frame-driven mwifiex/mac80211 defects.\nAC:L - No race must be won: the zero-initialized decoy privs permanently shadow `(bss_num 0, bss_type STA)` on any device operating in AP/hotspot mode, and privs left behind by `mwifiex_del_virtual_intf()` keep matching their old BSS id indefinitely, so a steady stream of frames/events reliably lands on an unused priv.\nPR:N - The attacker needs no credentials or association on the target \u2014 unassociated beacons/probe responses feed the scan-result event path and received frames feed the RX data path, both of which are processed before any authentication state matters.\nUI:N - No victim action is required; the stale-priv condition is the device\u0027s steady-state configuration in AP/hotspot deployments and after any routine interface teardown, and the driver processes the offending events and frames autonomously in a workqueue/IRQ context.\nS:U - Both the flawed lookup and its consequences are confined to the kernel\u0027s own security authority within the mwifiex driver; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - A stale priv causes reads through dangling and never-initialized pointers, and on a deleted interface the freed `priv-\u003ehist_data` object continues to be accessed (including read back via the debugfs histogram after reallocation), giving disclosure of reused heap contents; per use-after-free treatment this is High.\nI:H - `mwifiex_hist_data_add()`/`mwifiex_hist_data_set()` perform `atomic_inc()` into the freed `hist_data` buffer at offsets derived from the received frame\u0027s `rx_rate`/`snr`/`nf` fields (with `rssi = snr - nflr` able to index past the arrays), yielding an out-of-bounds write primitive on freed heap memory that is exploitable for control-flow influence.\nA:H - The commit documents a reproducible kernel oops \u2014 NULL dereference of `priv-\u003ewdev.wiphy-\u003ebands[]` in `mwifiex_get_cfp()` \u2014 and the same stale priv also NULL-derefs `priv-\u003enetdev` in `eth_type_trans()`, producing a kernel panic."

In the past, there were similar failures reported by CI from other IGT
tests, observed on other platforms.
Before commit 63baf4f3d587 ("drm/i915/gt: Only wait for GPU activity
before unbinding a GGTT fence"), i915_vma_revoke_fence() was waiting for
idleness of vma->active via fence_update(). That commit introduced
vma->fence->active in order for the fence_update() to be able to wait
selectively on that one instead of vma->active since only idleness of
fence registers was needed. But then, another commit 0d86ee35097a
("drm/i915/gt: Make fence revocation unequivocal") replaced the call to
fence_update() in i915_vma_revoke_fence() with only fence_write(), and
also added that GEM_BUG_ON(!i915_active_is_idle(&fence->active)) in front.
No justification was provided on why we might then expect idleness of
vma->fence->active without first waiting on it.
The issue can be potentially caused by a race among revocation of fence
registers on one side and sequential execution of signal callbacks invoked
on completion of a request that was using them on the other, still
processed in parallel to revocation of those fence registers. Fix it by
waiting for idleness of vma->fence->active in i915_vma_revoke_fence().

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ks8851: Fix deadlock with the SPI chip variant
When SMP is enabled and spinlocks are actually functional then there is
a deadlock with the 'statelock' spinlock between ks8851_start_xmit_spi
and ks8851_irq:
watchdog: BUG: soft lockup - CPU#0 stuck for 27s!

This issue has not been identified earlier because tests were done on
a device with SMP disabled and so spinlocks were actually NOPs.
Now use spin_(un)lock_bh for TX queue related locking to avoid execution
of softirq work synchronously that would lead to a deadlock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/fbdev-dma: Only set smem_start is enable per module option
Only export struct fb_info.fix.smem_start if that is required by the
user and the memory does not come from vmalloc().
Setting struct fb_info.fix.smem_start breaks systems where DMA
memory is backed by vmalloc address space. An example error is
shown below.

Additionally, DMA memory is assumed to by contiguous in physical
address space, which is not guaranteed by vmalloc().
Resolve this by checking the module flag drm_leak_fbdev_smem when
DRM allocated the instance of struct fb_info. Fbdev-dma then only
sets smem_start only if required (via FBINFO_HIDE_SMEM_START). Also
guarantee that the framebuffer is not located in vmalloc address
space.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ibmvnic: Add tx check to prevent skb leak
Below is a summary of how the driver stores a reference to an skb during
transmit:
tx_buff[free_map[consumer_index]]->skb = new_skb;
free_map[consumer_index] = IBMVNIC_INVALID_MAP;
consumer_index ++;
Where variable data looks like this:
free_map == [4, IBMVNIC_INVALID_MAP, IBMVNIC_INVALID_MAP, 0, 3]
consumer_index^
tx_buff == [skb=null, skb=<ptr>, skb=<ptr>, skb=null, skb=null]
The driver has checks to ensure that free_map[consumer_index] pointed to
a valid index but there was no check to ensure that this index pointed
to an unused/null skb address. So, if, by some chance, our free_map and
tx_buff lists become out of sync then we were previously risking an
skb memory leak. This could then cause tcp congestion control to stop
sending packets, eventually leading to ETIMEDOUT.
Therefore, add a conditional to ensure that the skb address is null. If
not then warn the user (because this is still a bug that should be
patched) and free the old pointer to prevent memleak/tcp problems.

"value": "AV:N - The vulnerable code is `ibmvnic_xmit()`, the transmit path exercised by every outbound packet, on the primary network interface of PowerVM LPARs that commonly serve internet-facing workloads. Unauthenticated remote traffic both induces the TX-watchdog reset that desyncs the pools and drives the subsequent leaking transmits, with no local access required.\nAC:L - An attacker saturating the interface can stall the TX queue and trip the watchdog (`ibmvnic_tx_timeout` \u2192 `VNIC_RESET_TIMEOUT`) while packets are in flight, creating the free_map/tx_buff desync, then continue sending to leak an skb on essentially every transmit that lands on an untracked slot. Once desynced the leak is deterministic, not probabilistic.\nPR:N - No credentials or account are needed \u2014 any remote peer that sends traffic eliciting responses reaches the transmit path. No capability check, authentication gate, or privileged interface sits between the attacker and the vulnerable code.\nUI:N - The leak occurs autonomously inside the driver\u0027s transmit path as packets are processed. No administrator or user action is required at any point.\nS:U - The leaked memory and the stalled TCP connections are all within the affected kernel\u0027s own security authority. Although the adapter is backed by a VIOS partition, nothing crosses into the VIOS, the hypervisor, or other LPARs.\nC:N - There is no out-of-bounds read, use-after-free, or uninitialized-memory exposure \u2014 the stale skb pointer is overwritten, never dereferenced. The DMA long-term buffer is zeroed with `memset(dst, 0, tx_pool-\u003ebuf_size)` before every copy, so no residual kernel data can be emitted on the wire.\nI:N - No memory corruption, arbitrary write, or control-flow influence results; the defect is a dropped reference to a still-valid object. Nothing an attacker supplies modifies kernel data structures or stored data.\nA:H - Each leaked skb permanently pins the owning socket\u0027s `sk_wmem_alloc`, so congestion control halts transmission and connections fail with ETIMEDOUT, as the commit message states explicitly. Under sustained traffic this is unbounded kernel memory exhaustion combined with complete loss of network service on the affected system \u2014 not mere degradation."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Do not return negative stream id for array
[WHY]
resource_stream_to_stream_idx returns an array index and it return -1
when not found; however, -1 is not a valid array index number.
[HOW]
When this happens, call ASSERT(), and return a zero instead.
This fixes an OVERRUN and an NEGATIVE_RETURNS issues reported by Coverity.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cdrom: rearrange last_media_change check to avoid unintentional overflow
When running syzkaller with the newly reintroduced signed integer wrap
sanitizer we encounter this splat:
[ 366.015950] UBSAN: signed-integer-overflow in ../drivers/cdrom/cdrom.c:2361:33
[ 366.021089] -9223372036854775808 - 346321 cannot be represented in type '__s64' (aka 'long long')
[ 366.025894] program syz-executor.4 is using a deprecated SCSI ioctl, please convert it to SG_IO
[ 366.027502] CPU: 5 PID: 28472 Comm: syz-executor.7 Not tainted 6.8.0-rc2-00035-gb3ef86b5a957 #1

[ 366.027518] Call Trace:

[ 366.080231] ? __pfx_blkdev_ioctl+0x10/0x10
...
Historically, the signed integer overflow sanitizer did not work in the
kernel due to its interaction with `-fwrapv` but this has since been
changed [1] in the newest version of Clang. It was re-enabled in the
kernel with Commit 557f8c582a9ba8ab ("ubsan: Reintroduce signed overflow
sanitizer").
Let's rearrange the check to not perform any arithmetic, thus not
tripping the sanitizer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: core: Check for unset descriptor
Make sure the descriptor has been set before looking at maxpacket.
This fixes a null pointer panic in this case.
This may happen if the gadget doesn't properly set up the endpoint
for the current speed, or the gadget descriptors are malformed and
the descriptor for the speed/endpoint are not found.
No current gadget driver is known to have this problem, but this
may cause a hard-to-find bug during development of new gadgets.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: qca: Fix BT enable failure again for QCA6390 after warm reboot
Commit 272970be3dab ("Bluetooth: hci_qca: Fix driver shutdown on closed
serdev") will cause below regression issue:
BT can't be enabled after below steps:
cold boot -> enable BT -> disable BT -> warm reboot -> BT enable failure
if property enable-gpios is not configured within DT|ACPI for QCA6390.
The commit is to fix a use-after-free issue within qca_serdev_shutdown()
by adding condition to avoid the serdev is flushed or wrote after closed
but also introduces this regression issue regarding above steps since the
VSC is not sent to reset controller during warm reboot.
Fixed by sending the VSC to reset controller within qca_serdev_shutdown()
once BT was ever enabled, and the use-after-free issue is also fixed by
this change since the serdev is still opened before it is flushed or wrote.
Verified by the reported machine Dell XPS 13 9310 laptop over below two
kernel commits:
commit e00fc2700a3f ("Bluetooth: btusb: Fix triggering coredump
implementation for QCA") of bluetooth-next tree.
commit b23d98d46d28 ("Bluetooth: btusb: Fix triggering coredump
implementation for QCA") of linus mainline tree.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ntb_netdev: Move ntb_netdev_rx_handler() to call netif_rx() from __netif_rx()
The following is emitted when using idxd (DSA) dmanegine as the data
mover for ntb_transport that ntb_netdev uses.

The cause is due to the idxd driver interrupt completion handler uses
threaded interrupt and the threaded handler is not hard or soft interrupt
context. However __netif_rx() can only be called from interrupt context.
Change the call to netif_rx() in order to allow completion via normal
context for dmaengine drivers that utilize threaded irq handling.
While the following commit changed from netif_rx() to __netif_rx(),
baebdf48c360 ("net: dev: Makes sure netif_rx() can be invoked in any context."),
the change should've been a noop instead. However, the code precedes this
fix should've been using netif_rx_ni() or netif_rx_any_context().

"value": "AV:N - The vulnerable code is a network receive handler bound to the kernel network stack; it runs on every frame arriving on the ntb_netdev Ethernet interface, with the payload supplied by a remote peer over the NTB interconnect. In the dual-controller storage and cluster deployments NTB exists for, that interconnect carries routed/bridged IP traffic, so packets originating more than one hop away reach `ntb_netdev_rx_handler()` and no local access to the target is needed.\nAC:L - Scored in the vulnerable configuration (`ntb_transport use_dma=1` with a threaded-completion dmaengine such as idxd/DSA, exactly what the report documents), every frame at or above the default `copy_bytes=1024` threshold takes `ntb_async_rx()` and completes in the preemptible `idxd_wq_thread` IRQ kthread, so ordinary MTU-sized traffic hits `__netif_rx()` in preemptible context 100% of the time. There is no race to win, no timing window, and no memory-layout precondition \u2014 the attacker sets the rate and the frame size.\nPR:N - The path is raw Ethernet frame reception \u2014 `eth_type_trans()` and `__netif_rx()` run before any protocol, socket, or application-layer authentication, and nothing on the path calls `capable()` or checks credentials. The attacker needs no account, session, or key on the target.\nUI:N - The attacker generates the frames and the NTB doorbell, tasklet, DMA submission, and idxd completion thread all run autonomously as part of normal interface operation. No administrator or second user has to log in, mount, open, or configure anything.\nS:U - The preemption violation, the deferred softirq, and any resulting backlog corruption or panic all occur inside the kernel that owns the ntb_netdev interface and the per-CPU `softnet_data`; no VM, hypervisor, IOMMU, or sandbox boundary is crossed.\nC:N - There is no out-of-bounds read, use-after-free, or uninitialized-memory disclosure \u2014 `enqueue_to_backlog()` is passed a valid `struct softnet_data` and the skb is a properly sized, driver-allocated buffer. The only artifact is the rate-limited `BUG:`/`dump_stack()` in dmesg, which prints symbol+offset rather than raw addresses and is not observable by the packet-sending attacker at all.\nI:N - On any realistic affected system `CONFIG_RPS` is set (`default y`, disabled only when `SMP=n`, which removes the race, or `SYSFS=n`, absent on the x86 servers NTB ships on), so `backlog_lock_irq_save()` takes `spin_lock_irqsave(\u0026sd-\u003einput_pkt_queue.lock)` and every cross-CPU backlog access stays properly serialized. Packets themselves are delivered unmodified \u2014 merely late \u2014 and no attacker-controlled data lands in unintended kernel memory.\nA:H - `__netif_rx()`\u0027s `lockdep_assert_once(hardirq_count() | softirq_count())` is a `WARN_ON_ONCE`, so on `CONFIG_PROVE_LOCKING` kernels booted with `panic_on_warn=1` \u2014 standard for fail-fast storage appliances and CI fleets \u2014 the first frame panics the host outright. Even without that, `napi_schedule_rps()` only sets the `NET_RX_SOFTIRQ` pending bit and nothing drains it (the fix\u0027s `local_bh_enable()` is precisely what restores that), so under sustained peer traffic the backlog exceeds `netdev_max_backlog` and packets are discarded in `cpu_backlog_drop`, stalling the node interconnect; and on SMP builds where `CONFIG_RPS` is off, the bare `local_irq_save()` leaves a migrated thread corrupting a remote CPU\u0027s `input_pkt_queue` and `backlog.state`, producing skb list corruption and an oops."

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/bhi: Avoid warning in #DB handler due to BHI mitigation
When BHI mitigation is enabled, if SYSENTER is invoked with the TF flag set
then entry_SYSENTER_compat() uses CLEAR_BRANCH_HISTORY and calls the
clear_bhb_loop() before the TF flag is cleared. This causes the #DB handler
(exc_debug_kernel()) to issue a warning because single-step is used outside the
entry_SYSENTER_compat() function.
To address this issue, entry_SYSENTER_compat() should use CLEAR_BRANCH_HISTORY
after making sure the TF flag is cleared.
The problem can be reproduced with the following sequence:
$ cat sysenter_step.c
int main()
{ asm("pushf; pop %ax; bts $8,%ax; push %ax; popf; sysenter"); }
$ gcc -o sysenter_step sysenter_step.c
$ ./sysenter_step
Segmentation fault (core dumped)
The program is expected to crash, and the #DB handler will issue a warning.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: atm: cxacru: fix endpoint checking in cxacru_bind()
Syzbot is still reporting quite an old issue [1] that occurs due to
incomplete checking of present usb endpoints. As such, wrong
endpoints types may be used at urb sumbitting stage which in turn
triggers a warning in usb_submit_urb().
Fix the issue by verifying that required endpoint types are present
for both in and out endpoints, taking into account cmd endpoint type.
Unfortunately, this patch has not been tested on real hardware.
[1] Syzbot report:

Summary
In the Linux kernel, the following vulnerability has been resolved:
xdp: Remove WARN() from __xdp_reg_mem_model()
syzkaller reports a warning in __xdp_reg_mem_model().
The warning occurs only if __mem_id_init_hash_table() returns an error. It
returns the error in two cases:
1. memory allocation fails;
2. rhashtable_init() fails when some fields of rhashtable_params
struct are not initialized properly.
The second case cannot happen since there is a static const rhashtable_params
struct with valid fields. So, warning is only triggered when there is a
problem with memory allocation.
Thus, there is no sense in using WARN() to handle this error and it can be
safely removed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
irqchip/imx-irqsteer: Handle runtime power management correctly
The power domain is automatically activated from clk_prepare(). However, on
certain platforms like i.MX8QM and i.MX8QXP, the power-on handling invokes
sleeping functions, which triggers the 'scheduling while atomic' bug in the
context switch path during device probing:
BUG: scheduling while atomic: kworker/u13:1/48/0x00000002

Cure this by implementing the irq_bus_lock/sync_unlock() interrupt chip
callbacks and handle power management in them as they are invoked from
non-atomic context.

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: mcp251xfd: fix infinite loop when xmit fails
When the mcp251xfd_start_xmit() function fails, the driver stops
processing messages, and the interrupt routine does not return,
running indefinitely even after killing the running application.
Error messages:
[ 441.298819] mcp251xfd spi2.0 can0: ERROR in mcp251xfd_start_xmit: -16
[ 441.306498] mcp251xfd spi2.0 can0: Transmit Event FIFO buffer not empty. (seq=0x000017c7, tef_tail=0x000017cf, tef_head=0x000017d0, tx_head=0x000017d3).
... and repeat forever.
The issue can be triggered when multiple devices share the same SPI
interface. And there is concurrent access to the bus.
The problem occurs because tx_ring->head increments even if
mcp251xfd_start_xmit() fails. Consequently, the driver skips one TX
package while still expecting a response in
mcp251xfd_handle_tefif_one().
Resolve the issue by starting a workqueue to write the tx obj
synchronously if err = -EBUSY. In case of another error, decrement
tx_ring->head, remove skb from the echo stack, and drop the message.
[mkl: use more imperative wording in patch description]

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: mark bpf_dummy_struct_ops.test_1 parameter as nullable
Test case dummy_st_ops/dummy_init_ret_value passes NULL as the first
parameter of the test_1() function. Mark this parameter as nullable to
make verifier aware of such possibility.
Otherwise, NULL check in the test_1() code:
SEC("struct_ops/test_1")
int BPF_PROG(test_1, struct bpf_dummy_ops_state *state)
{
if (!state)
return ...;
... access state ...
}
Might be removed by verifier, thus triggering NULL pointer dereference
under certain conditions.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: MT - limit max slots
syzbot is reporting too large allocation at input_mt_init_slots(), for
num_slots is supplied from userspace using ioctl(UI_DEV_CREATE).
Since nobody knows possible max slots, this patch chose 1024.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: fsl-asoc-card: set priv->pdev before using it
priv->pdev pointer was set after being used in
fsl_asoc_card_audmux_init().
Move this assignment at the start of the probe function, so
sub-functions can correctly use pdev through priv.
fsl_asoc_card_audmux_init() dereferences priv->pdev to get access to the
dev struct, used with dev_err macros.
As priv is zero-initialised, there would be a NULL pointer dereference.
Note that if priv->dev is dereferenced before assignment but never used,
for example if there is no error to be printed, the driver won't crash
probably due to compiler optimisations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: txgbe: remove separate irq request for MSI and INTx
When using MSI or INTx interrupts, request_irq() for pdev->irq will
conflict with request_threaded_irq() for txgbe->misc.irq, to cause
system crash. So remove txgbe_request_irq() for MSI/INTx case, and
rename txgbe_request_msix_irqs() since it only request for queue irqs.
Add wx->misc_irq_domain to determine whether the driver creates an IRQ
domain and threaded request the IRQs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: aacraid: Fix double-free on probe failure
aac_probe_one() calls hardware-specific init functions through the
aac_driver_ident::init pointer, all of which eventually call down to
aac_init_adapter().
If aac_init_adapter() fails after allocating memory for aac_dev::queues,
it frees the memory but does not clear that member.
After the hardware-specific init function returns an error,
aac_probe_one() goes down an error path that frees the memory pointed to
by aac_dev::queues, resulting.in a double-free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/mtrr: Check if fixed MTRRs exist before saving them
MTRRs have an obsolete fixed variant for fine grained caching control
of the 640K-1MB region that uses separate MSRs. This fixed variant has
a separate capability bit in the MTRR capability MSR.
So far all x86 CPUs which support MTRR have this separate bit set, so it
went unnoticed that mtrr_save_state() does not check the capability bit
before accessing the fixed MTRR MSRs.
Though on a CPU that does not support the fixed MTRR capability this
results in a #GP. The #GP itself is harmless because the RDMSR fault is
handled gracefully, but results in a WARN_ON().
Add the missing capability check to prevent this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
null_blk: fix validation of block size
Block size should be between 512 and PAGE_SIZE and be a power of 2. The current
check does not validate this, so update the check.
Without this patch, null_blk would Oops due to a null pointer deref when
loaded with bs=1536 [1].
[axboe: remove unnecessary braces and != 0 check]

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: cs_dsp: Return error if block header overflows file
Return an error from cs_dsp_power_up() if a block header is longer
than the amount of data left in the file.
The previous code in cs_dsp_load() and cs_dsp_load_coeff() would loop
while there was enough data left in the file for a valid region. This
protected against overrunning the end of the file data, but it didn't
abort the file processing with an error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Validate ff offset
This adds sanity checks for ff offset. There is a check
on rt->first_free at first, but walking through by ff
without any check. If the second ff is a large offset.
We may encounter an out-of-bound read.

"value": "AV:L - The vulnerable code is reached only through `mount()` of a crafted NTFS volume, whose `$LogFile` is parsed by `log_replay()` during `ntfs_fill_super()`. No network or remote peer is involved, and the image can be supplied as a local file/loop device rather than requiring physical media, so Local is the correct (and higher-severity) vector versus Physical.\nAC:L - Every field driving the bug (`rt-\u003esize`, `rt-\u003eused`, `rt-\u003efirst_free`, `rt-\u003elast_free`, and the free-list words) is attacker-authored data in the image, so the out-of-bounds offset is chosen deterministically with no race, memory-layout guess, or environmental precondition.\nPR:L - ntfs3 is `FS_REQUIRES_DEV` without `FS_USERNS_MOUNT`, so mounting is not reachable from an unprivileged user namespace, but on desktop/kiosk/workstation deployments an ordinary logged-in local user can get an attacker-supplied NTFS volume mounted via udisks2/automount policy without any administrative credential.\nUI:N - The attacker performs the mount themselves (or automount/udisks2 does it the moment the device appears) and log replay runs unconditionally on every mount, read-only included; no separate victim has to open a file or take any action.\nS:U - The out-of-bounds accesses occur in kernel memory within the same security authority that already owns the mount; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The unvalidated free-list walk performs 4-byte reads at attacker-chosen offsets of up to ~4 GB beyond the slab object, and the walk\u0027s outcome (terminate, hit `RESTART_ENTRY_ALLOCATED`, or spin) is observable through mount success/failure, turning the wild reads into a probing oracle over kernel heap contents.\nI:H - Because `check_rstbl()` is the sole validator of `first_free`/`last_free` before the tables reach `free_rsttbl_idx()`, `alloc_rsttbl_idx()`, and `extend_rsttbl()`, a corrupted list yields out-of-bounds 4-byte slab writes with attacker-influenced values (`*(__le32 *)Add2Ptr(rt, lf) = off_le`, `*last_e = *e`), which is heap corruption usable for control-flow-relevant metadata overwrite.\nA:H - A wild read up to 4 GB from the buffer readily faults on unmapped kernel memory, producing an oops/panic, and a cyclic free list makes the unbounded `for (off = ff; off;)` / `for (;;)` walks loop forever with no reschedule, hanging the mounting task and CPU."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bluetooth/l2cap: sync sock recv cb and release
The problem occurs between the system call to close the sock and hci_rx_work,
where the former releases the sock and the latter accesses it without lock protection.
CPU0 CPU1
---- ----
sock_close hci_rx_work
l2cap_sock_release hci_acldata_packet
l2cap_sock_kill l2cap_recv_frame
sk_free l2cap_conless_channel
l2cap_sock_recv_cb
If hci_rx_work processes the data that needs to be received before the sock is
closed, then everything is normal; Otherwise, the work thread may access the
released sock when receiving data.
Add a chan mutex in the rx callback of the sock to achieve synchronization between
the sock release and recv cb.
Sock is dead, so set chan data to NULL, avoid others use invalid sock pointer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: Don't issue ATS Invalidation request when device is disconnected
For those endpoint devices connect to system via hotplug capable ports,
users could request a hot reset to the device by flapping device's link
through setting the slot's link control register, as pciehp_ist() DLLSC
interrupt sequence response, pciehp will unload the device driver and
then power it off. thus cause an IOMMU device-TLB invalidation (Intel
VT-d spec, or ATS Invalidation in PCIe spec r6.1) request for non-existence
target device to be sent and deadly loop to retry that request after ITE
fault triggered in interrupt context.
That would cause following continuous hard lockup warning and system hang

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: i2c: et8ek8: Don't strip remove function when driver is builtin
Using __exit for the remove function results in the remove callback
being discarded with CONFIG_VIDEO_ET8EK8=y. When such a device gets
unbound (e.g. using sysfs or hotplug), the driver is just removed
without the cleanup being performed. This results in resource leaks. Fix
it by compiling in the remove callback unconditionally.
This also fixes a W=1 modpost warning:
WARNING: modpost: drivers/media/i2c/et8ek8/et8ek8: section mismatch in reference: et8ek8_i2c_driver+0x10 (section: .data) -> et8ek8_remove (section: .exit.text)

No network or physical access is involved.\nAC:L - The missing `.remove` callback is unconditional when the driver is builtin, so cleanup is deterministically skipped on every unbind; the resulting NULL deref via the stale 0444 sysfs attribute and the dangling subdev registrations are reachable reliably with no race to win.\nPR:L - Once the driver has been unbound, an ordinary unprivileged local user reads the leftover world-readable `priv_mem` attribute or opens the still-registered `/dev/v4l-subdevX` devnode to reach the freed `et8ek8_sensor`; no capability is needed for that step, and it is not obtainable-only-as-root.\nUI:R - The dangling state only comes into existence after the driver is detached from the device (sysfs unbind, i2c adapter teardown, or DT overlay removal), which is an administrative/system action performed by someone other than the attacker.\nS:U - The corruption and its consequences are confined to the kernel\u0027s own memory and the V4L2/media subsystem; no VM, IOMMU, or other security-authority boundary is crossed.\nC:H - The freed `sensor` remains on `mdev-\u003eentities` and the global `subdev_list`, so `MEDIA_IOC_ENUM_ENTITIES`/`G_TOPOLOGY` and subdev ioctls copy freed heap contents to userspace, and the use-after-free gives a general read primitive over reallocated kernel objects.\nI:H - The devm-freed object is still dereferenced through `sd-\u003eops` and `sd-\u003einternal_ops` function pointers on later subdev ioctls and async-notifier matching, so heap-spraying the freed allocation yields a write and control-flow hijack primitive.\nA:H - Reading the orphaned world-readable `priv_mem` sysfs file dereferences a NULL `dev_get_drvdata()` result and oopses the kernel, and the use-after-free on the still-registered subdev/media entity causes further crashes."

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: add missing condition check for existence of mapped data
nvme_map_data() is called when request has physical segments, hence
the nvme_unmap_data() should have same condition to avoid dereference.

There is no remote or adjacent-network path to this code.\nAC:L - The error path is entered when the metadata DMA mapping fails, which an attacker can drive by flooding concurrent I/O to exhaust swiotlb bounce-buffer slots or IOVA space (guaranteed bounce-through in confidential-compute guests or DMA-mask-limited setups), and the stale `iod` state is deterministic once the path is taken. No timing race the attacker cannot control is involved.\nPR:L - Only an unprivileged local user with access to an NVMe namespace is required \u2014 normal file I/O on a PI/metadata-formatted namespace sets `REQ_INTEGRITY` with no capability at all, and `nvme_cmd_allowed()` explicitly permits unprivileged passthrough of non-intrusive I/O commands without `CAP_SYS_ADMIN`.\nUI:N - The attacker triggers the condition entirely through its own I/O submissions; no action by another user or administrator is needed.\nS:U - The corruption is confined to kernel memory and DMA mappings managed by the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `nvme_unmap_data()` reads a stale, already-freed `iod-\u003esgt.sgl` scatterlist, and the resulting mempool double-free lets two concurrent requests share one SGL so one request\u0027s data can be steered into another\u0027s buffers; spurious `dma_unmap_page()` of a reassigned IOVA can likewise expose unrelated memory contents to the device.\nI:H - The double `mempool_free()` of the scatterlist is a heap double-free primitive suitable for controlled heap corruption, and tearing down a DMA mapping that has been reallocated leaves the device DMA-writing into memory now owned by other subsystems \u2014 both give arbitrary-write-class integrity impact.\nA:H - The path hits `WARN_ON_ONCE()` and then unmaps DMA using garbage addresses and frees an invalid pointer, producing IOMMU faults, slab/mempool corruption, and kernel oops or panic."

In the Linux kernel, the following vulnerability has been resolved:
cachefiles: fix slab-use-after-free in fscache_withdraw_volume()
We got the following issue in our fault injection stress test:

fscache_relinquish_volume

kfree(fscache_volume)
cachefiles_withdraw_volume
fscache_withdraw_volume
fscache_volume->n_accesses
// fscache_volume UAF !!!
The fscache_volume in cache->volumes must not have been freed yet, but its
reference count may be 0. So use the new fscache_try_get_volume() helper
function try to get its reference count.
If the reference count of fscache_volume is 0, fscache_put_volume() is
freeing it, so wait for it to be removed from cache->volumes.
If its reference count is not 0, call cachefiles_withdraw_volume() with
reference count protection to avoid the above issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix too early release of tcx_entry
Pedro Pinto and later independently also Hyunwoo Kim and Wongi Lee reported
an issue that the tcx_entry can be released too early leading to a use
after free (UAF) when an active old-style ingress or clsact qdisc with a
shared tc block is later replaced by another ingress or clsact instance.
Essentially, the sequence to trigger the UAF (one example) can be as follows:
1. A network namespace is created
2. An ingress qdisc is created. This allocates a tcx_entry, and
&tcx_entry->miniq is stored in the qdisc's miniqp->p_miniq. At the
same time, a tcf block with index 1 is created.
3. chain0 is attached to the tcf block. chain0 must be connected to
the block linked to the ingress qdisc to later reach the function
tcf_chain0_head_change_cb_del() which triggers the UAF.
4. Create and graft a clsact qdisc. This causes the ingress qdisc
created in step 1 to be removed, thus freeing the previously linked
tcx_entry:
rtnetlink_rcv_msg()
=> tc_modify_qdisc()
=> qdisc_create()
=> clsact_init() [a]
=> qdisc_graft()
=> qdisc_destroy()
=> __qdisc_destroy()
=> ingress_destroy() [b]
=> tcx_entry_free()
=> kfree_rcu() // tcx_entry freed
5. Finally, the network namespace is closed. This registers the
cleanup_net worker, and during the process of releasing the
remaining clsact qdisc, it accesses the tcx_entry that was
already freed in step 4, causing the UAF to occur:
cleanup_net()
=> ops_exit_list()
=> default_device_exit_batch()
=> unregister_netdevice_many()
=> unregister_netdevice_many_notify()
=> dev_shutdown()
=> qdisc_put()
=> clsact_destroy() [c]
=> tcf_block_put_ext()
=> tcf_chain0_head_change_cb_del()
=> tcf_chain_head_change_item()
=> clsact_chain_head_change()
=> mini_qdisc_pair_swap() // UAF
There are also other variants, the gist is to add an ingress (or clsact)
qdisc with a specific shared block, then to replace that qdisc, waiting
for the tcx_entry kfree_rcu() to be executed and subsequently accessing
the current active qdisc's miniq one way or another.
The correct fix is to turn the miniq_active boolean into a counter. What
can be observed, at step 2 above, the counter transitions from 0->1, at
step [a] from 1->2 (in order for the miniq object to remain active during
the replacement), then in [b] from 2->1 and finally [c] 1->0 with the
eventual release. The reference counter in general ranges from [0,2] and
it does not need to be atomic since all access to the counter is protected
by the rtnl mutex. With this in place, there is no longer a UAF happening
and the tcx_entry is freed at the correct time.

No remote packet can drive the qdisc configuration path.\nAC:L - The attacker deterministically controls every step \u2014 create netns, create ingress qdisc with a shared block, attach chain0, graft a clsact qdisc to free the tcx_entry, then close the netns \u2014 with all mutations serialized under the rtnl mutex, so there is no race to win, only an RCU grace period to wait out. Heap grooming of the kmalloc-2048 slot is entirely under attacker control.\nPR:L - `rtnetlink_rcv_msg()` gates qdisc creation on `netlink_net_capable(skb, CAP_NET_ADMIN)` evaluated against the netns owner\u0027s user namespace, so an unprivileged local user obtains it with `unshare -Urn` \u2014 the published trigger sequence itself begins by creating a network namespace. No real root or init-namespace privilege is needed.\nUI:N - The entire sequence is performed by the attacker\u0027s own process; the final UAF fires from the `cleanup_net` worker triggered by the attacker closing its own network namespace. No victim action of any kind is involved.\nS:U - The corruption occurs in kernel heap memory and the impact stays within the same kernel security authority (local privilege escalation). No hypervisor, IOMMU, or other security-authority boundary is crossed.\nC:H - This is a use-after-free with an attacker-timed read of the freed `tcx_entry-\u003eminiq` slot, and the reclaimed ~1.6 KB kmalloc-2048 object can be sprayed with attacker-chosen structures, giving a path to disclose kernel heap pointers and read arbitrary kernel memory via a corrupted `mini_Qdisc`/`filter_list` chain.\nI:H - `mini_qdisc_pair_swap()` writes a kernel pointer (or NULL) into offset 0 of the freed object, corrupting whatever object was reallocated there, and the write can be repeated on demand by adding/removing filters on the shared block. Combined with the RX path\u0027s indirect call through `miniq-\u003efilter_list` in `tcf_classify()`, this yields a control-flow hijack primitive suitable for full privilege escalation.\nA:H - Even without successful exploitation, the use-after-free write into freed slab memory reliably corrupts unrelated kernel objects and panics the machine (KASAN-detected UAF, oops in `mini_qdisc_pair_swap`/`cleanup_net`). It can be triggered repeatedly by any unprivileged local user."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ila: block BH in ila_output()
As explained in commit 1378817486d6 ("tipc: block BH
before using dst_cache"), net/core/dst_cache.c
helpers need to be called with BH disabled.
ila_output() is called from lwtunnel_output()
possibly from process context, and under rcu_read_lock().
We might be interrupted by a softirq, re-enter ila_output()
and corrupt dst_cache data structures.
Fix the race by using local_bh_disable().

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: hisilicon/debugfs - Fix debugfs uninit process issue
During the zip probe process, the debugfs failure does not stop
the probe. When debugfs initialization fails, jumping to the
error branch will also release regs, in addition to its own
rollback operation.
As a result, it may be released repeatedly during the regs
uninit process. Therefore, the null check needs to be added to
the regs uninit process.

Summary
In the Linux kernel, the following vulnerability has been resolved:
leds: trigger: Unregister sysfs attributes before calling deactivate()
Triggers which have trigger specific sysfs attributes typically store
related data in trigger-data allocated by the activate() callback and
freed by the deactivate() callback.
Calling device_remove_groups() after calling deactivate() leaves a window
where the sysfs attributes show/store functions could be called after
deactivation and then operate on the just freed trigger-data.
Move the device_remove_groups() call to before deactivate() to close
this race window.
This also makes the deactivation path properly do things in reverse order
of the activation path which calls the activate() callback before calling
device_add_groups().

Summary
In the Linux kernel, the following vulnerability has been resolved:
cachefiles: wait for ondemand_object_worker to finish when dropping object
When queuing ondemand_object_worker() to re-open the object,
cachefiles_object is not pinned. The cachefiles_object may be freed when
the pending read request is completed intentionally and the related
erofs is umounted. If ondemand_object_worker() runs after the object is
freed, it will incur use-after-free problem as shown below.
process A processs B process C process D
cachefiles_ondemand_send_req()
// send a read req X
// wait for its completion
// close ondemand fd
cachefiles_ondemand_fd_release()
// set object as CLOSE
cachefiles_ondemand_daemon_read()
// set object as REOPENING
queue_work(fscache_wq, &info->ondemand_work)
// close /dev/cachefiles
cachefiles_daemon_release
cachefiles_flush_reqs
complete(&req->done)
// read req X is completed
// umount the erofs fs
cachefiles_put_object()
// object will be freed
cachefiles_ondemand_deinit_obj_info()
kmem_cache_free(object)
// both info and object are freed
ondemand_object_worker()
When dropping an object, it is no longer necessary to reopen the object,
so use cancel_work_sync() to cancel or wait for ondemand_object_worker()
to finish.

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: cs_dsp: Fix overflow checking of wmfw header
Fix the checking that firmware file buffer is large enough for the
wmfw header, to prevent overrunning the buffer.
The original code tested that the firmware data buffer contained
enough bytes for the sums of the size of the structs
wmfw_header + wmfw_adsp1_sizes + wmfw_footer
But wmfw_adsp1_sizes is only used on ADSP1 firmware. For ADSP2 and
Halo Core the equivalent struct is wmfw_adsp2_sizes, which is
4 bytes longer. So the length check didn't guarantee that there
are enough bytes in the firmware buffer for a header with
wmfw_adsp2_sizes.
This patch splits the length check into three separate parts. Each
of the wmfw_header, wmfw_adsp?_sizes and wmfw_footer are checked
separately before they are used.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Squashfs: sanity check symbolic link size
Syzkiller reports a "KMSAN: uninit-value in pick_link" bug.
This is caused by an uninitialised page, which is ultimately caused
by a corrupted symbolic link size read from disk.
The reason why the corrupted symlink size causes an uninitialised
page is due to the following sequence of events:
1. squashfs_read_inode() is called to read the symbolic
link from disk. This assigns the corrupted value
3875536935 to inode->i_size.
2. Later squashfs_symlink_read_folio() is called, which assigns
this corrupted value to the length variable, which being a
signed int, overflows producing a negative number.
3. The following loop that fills in the page contents checks that
the copied bytes is less than length, which being negative means
the loop is skipped, producing an uninitialised page.
This patch adds a sanity check which checks that the symbolic
link size is not larger than expected.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: mediatek: mt8195: Add platform entry for ETDM1_OUT_BE dai link
Commit e70b8dd26711 ("ASoC: mediatek: mt8195: Remove afe-dai component
and rework codec link") removed the codec entry for the ETDM1_OUT_BE
dai link entirely instead of replacing it with COMP_EMPTY(). This worked
by accident as the remaining COMP_EMPTY() platform entry became the codec
entry, and the platform entry became completely empty, effectively the
same as COMP_DUMMY() since snd_soc_fill_dummy_dai() doesn't do anything
for platform entries.
This causes a KASAN out-of-bounds warning in mtk_soundcard_common_probe()
in sound/soc/mediatek/common/mtk-soundcard-driver.c:
for_each_card_prelinks(card, i, dai_link) {
if (adsp_node && !strncmp(dai_link->name, "AFE_SOF", strlen("AFE_SOF")))
dai_link->platforms->of_node = adsp_node;
else if (!dai_link->platforms->name && !dai_link->platforms->of_node)
dai_link->platforms->of_node = platform_node;
}
where the code expects the platforms array to have space for at least one entry.
Add an COMP_EMPTY() entry so that dai_link->platforms has space.

Success is 100% reliable.\nPR:L - The out-of-bounds access occurs during normal driver probe without requiring any elevated capability, consistent with the repo\u0027s treatment of ASoC probe-time flaws (e.g. CVE-2024-56685, CVE-2024-57880) as PR:L. A local unprivileged presence on the system is the baseline attacker model.\nUI:N - No victim action is needed; the corruption happens automatically during driver probe at boot or module load. Nothing must be opened, mounted, or clicked.\nS:U - Both the flawed code and the corrupted memory are kernel globals within the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:L - The loop reads `platforms-\u003ename` and `platforms-\u003eof_node` past the end of a zero-sized global array, disclosing adjacent kernel .bss/.data contents into the KASAN report, and kernel addresses/contents are exposed via the resulting splat. The read is bounded to a single 16-byte struct at a fixed offset rather than an arbitrary-length read.\nI:H - `dai_link-\u003eplatforms-\u003eof_node = platform_node` performs an out-of-bounds write of an 8-byte kernel pointer into adjacent global kernel data, silently corrupting neighboring `snd_soc_dai_link_component` state on non-KASAN builds. Out-of-bounds writes into kernel memory represent a total integrity loss within the kernel\u0027s scope.\nA:H - The condition produces a KASAN global-out-of-bounds BUG report (a panic under panic_on_warn), and on non-instrumented kernels corrupts adjacent global component descriptors used for DAI/component matching, destabilizing the audio subsystem during probe. This matches the A:H assigned across comparable ASoC probe-time defects in this tree."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/iucv: Avoid explicit cpumask var allocation on stack
For CONFIG_CPUMASK_OFFSTACK=y kernel, explicit allocation of cpumask
variable on stack is not recommended since it can cause potential stack
overflow.
Instead, kernel code should always use *cpumask_var API(s) to allocate
cpumask var in config-neutral way, leaving allocation strategy to
CONFIG_CPUMASK_OFFSTACK.
Use *cpumask_var API(s) to address it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: acpi: Harden get_cpu_for_acpi_id() against missing CPU entry
In a review discussion of the changes to support vCPU hotplug where
a check was added on the GICC being enabled if was online, it was
noted that there is need to map back to the cpu and use that to index
into a cpumask. As such, a valid ID is needed.
If an MPIDR check fails in acpi_map_gic_cpu_interface() it is possible
for the entry in cpu_madt_gicc[cpu] == NULL. This function would
then cause a NULL pointer dereference. Whilst a path to trigger
this has not been established, harden this caller against the
possibility.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: ucsi: Fix null pointer dereference in trace
ucsi_register_altmode checks IS_ERR for the alt pointer and treats
NULL as valid. When CONFIG_TYPEC_DP_ALTMODE is not enabled,
ucsi_register_displayport returns NULL which causes a NULL pointer
dereference in trace. Rather than return NULL, call
typec_port_register_altmode to register DisplayPort alternate mode
as a non-controllable mode when CONFIG_TYPEC_DP_ALTMODE is not enabled.

"value": "AV:N - The vulnerable code is in the IPv6 tunnel receive path, reached directly from `ipv6_rcv()` \u2192 `ip6_protocol_deliver_rcu()` \u2192 `gre_rcv()`/`ip6ip6_rcv()`/`ip4ip6_rcv()` when a host has an ip6tnl, ip6gre, ERSPAN or collect_md tunnel endpoint configured. A remote attacker triggers it purely by sending a crafted IPv6 packet (proto 47/41/4/137) with a truncated inner header.\nAC:L - The attacker fully controls the packet: simply emitting an outer IPv6+GRE header with zero/short inner payload deterministically reaches `dscp_ecn_decapsulate()` with the inner header absent from the linear area. No race, no memory-layout grooming, and no condition outside the attacker\u0027s control is required.\nPR:N - Tunnel decapsulation is completely unauthenticated \u2014 `ip6_tnl_rcv_ctl()`/`ip6_tnl_lookup()` only compare addresses and keys, and wildcard, `collect_md` and fallback tunnels match arbitrary sources. The attacker needs no account or credentials on the target.\nUI:N - Processing happens automatically in softirq context when the packet is received; no local user has to open, mount, or click anything.\nS:U - The uninitialized read and the out-of-bounds DSCP write are confined to kernel memory managed by the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:L - KMSAN confirms uninitialized kernel heap memory is read and consumed by `__INET_ECN_decapsulate()`, and the outcome is remotely observable (packet dropped vs. delivered, plus the ratelimited \"non-ECT from %pI6 with DS=%#x\" log), giving a repeatable oracle over stale heap contents. The exposure is strictly bounded to a couple of bytes within the skb\u0027s own buffer rather than an arbitrary read.\nI:L - On tunnels configured with `IP6_TNL_F_RCV_DSCP_COPY`, `ipv6_change_dsfield()`/`ipv4_change_dsfield()` perform an unchecked read-modify-write beyond the packet data (unlike the bounds-checked `INET_ECN_set_ce()`), modifying kernel memory that does not belong to the packet \u2014 in the zero-tailroom case the first bytes of `struct skb_shared_info`. The corruption is a few bytes at a fixed offset, not an arbitrary write.\nA:H - The unchecked DSCP write can land on `skb_shared_info`\u0027s `meta_len` and `frag_list` pointer bytes, corrupting a kernel pointer that is later dereferenced during skb traversal/free, yielding an oops; garbage-driven ECN decisions additionally cause spurious `rx_frame_errors` drops of tunnel traffic, and the condition is a hard KMSAN/instrumented-kernel abort. Any unauthenticated remote peer can repeat it indefinitely."

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: vhci-hcd: Do not drop references before new references are gained
At a few places the driver carries stale pointers
to references that can still be used. Make sure that does not happen.
This strictly speaking closes ZDI-CAN-22273, though there may be
similar races in the driver.

A malicious or compromised USB/IP server (or an on-path attacker, since USB/IP has no integrity protection) drives the bug entirely over the network.\nAC:L - The attacker controls both sides of the race \u2014 it forces unlimited re-enumerations by failing URBs (usb-storage error recovery and hub retry loops re-issue SET_ADDRESS/GET_DESCRIPTOR to devnum 0) and fires the reset event on demand with a single bad PDU byte. It also observes the GET_DESCRIPTOR-to-device-0 CMD_SUBMIT on the wire, so it knows precisely when the put/assign window opens, and can retry indefinitely.\nPR:N - The USB/IP client performs no authentication on received PDUs \u2014 `vhci_rx_loop()` just reads and dispatches whatever the peer sends, so the remote attacker needs no credentials on the target. Even in the local framing, `USBDEVFS_RESET` is gated only on `FMODE_WRITE` of the usbfs node with no capability check.\nUI:N - In the targeted deployments (thin clients, VDI USB redirection, device farms, industrial gateways) the attachment is established automatically by a service, and the attacker triggers both re-enumeration and the reset event itself during normal operation. No victim action is required at attack time.\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 double `usb_put_dev()` frees a live `struct usb_device` while `vdev-\u003eudev` and in-flight URBs still reference it, and the remote controls RET_SUBMIT buffer contents/sizes for reliable slab reclaim, yielding an arbitrary read primitive. `port_show_vhci()` additionally prints `dev_name()` from the freed object into `/sys/devices/platform/vhci_hcd.0/status`, directly leaking reclaimed heap content.\nI:H - After the premature free, `usb_get_dev()` performs a refcount increment into freed memory (a write at a controlled offset), and subsequent dereferences of `udev-\u003edev.driver`, `udev-\u003ebus`, and the kobject release path give function-pointer control. This is a classic UAF exploitable for heap corruption and control-flow hijack to kernel code execution.\nA:H - The reference-count underflow and stale-pointer dereference produce refcount_t warnings, oopses, and panics, and `vdev-\u003eudev` can also be observed as NULL/freed by concurrent readers. The remote peer can trigger this repeatedly, making a reliable kernel crash trivial."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Mark bpf prog stack with kmsan_unposion_memory in interpreter mode
syzbot reported uninit memory usages during map_{lookup,delete}_elem.
==========
BUG: KMSAN: uninit-value in __dev_map_lookup_elem kernel/bpf/devmap.c:441 [inline]
BUG: KMSAN: uninit-value in dev_map_lookup_elem+0xf3/0x170 kernel/bpf/devmap.c:796

__bpf_prog_run256+0xb5/0xe0 kernel/bpf/core.c:2237
==========
The reproducer should be in the interpreter mode.
The C reproducer is trying to run the following bpf prog:
0: (18) r0 = 0x0
2: (18) r1 = map[id:49]
4: (b7) r8 = 16777216
5: (7b) *(u64 *)(r10 -8) = r8
6: (bf) r2 = r10
7: (07) r2 += -229
^^^^^^^^^^
8: (b7) r3 = 8
9: (b7) r4 = 0
10: (85) call dev_map_lookup_elem#1543472
11: (95) exit
It is due to the "void *key" (r2) passed to the helper. bpf allows uninit
stack memory access for bpf prog with the right privileges. This patch
uses kmsan_unpoison_memory() to mark the stack as initialized.
This should address different syzbot reports on the uninit "void *key"
argument during map_{lookup,delete}_elem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: fully validate NFT_DATA_VALUE on store to data registers
register store validation for NFT_DATA_VALUE is conditional, however,
the datatype is always either NFT_DATA_VALUE or NFT_DATA_VERDICT. This
only requires a new helper function to infer the register type from the
set datatype so this conditional check can be removed. Otherwise,
pointer to chain object can be leaked through the registers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/drm_file: Fix pid refcounting race
<maarten.lankhorst@linux.intel.com>, Maxime Ripard
<mripard@kernel.org>, Thomas Zimmermann <tzimmermann@suse.de>
filp->pid is supposed to be a refcounted pointer; however, before this
patch, drm_file_update_pid() only increments the refcount of a struct
pid after storing a pointer to it in filp->pid and dropping the
dev->filelist_mutex, making the following race possible:
process A process B
========= =========
begin drm_file_update_pid
mutex_lock(&dev->filelist_mutex)
rcu_replace_pointer(filp->pid, <pid B>, 1)
mutex_unlock(&dev->filelist_mutex)
begin drm_file_update_pid
mutex_lock(&dev->filelist_mutex)
rcu_replace_pointer(filp->pid, <pid A>, 1)
mutex_unlock(&dev->filelist_mutex)
get_pid(<pid A>)
synchronize_rcu()
put_pid(<pid B>) *** pid B reaches refcount 0 and is freed here ***
get_pid(<pid B>) *** UAF ***
synchronize_rcu()
put_pid(<pid A>)
As far as I know, this race can only occur with CONFIG_PREEMPT_RCU=y
because it requires RCU to detect a quiescent state in code that is not
explicitly calling into the scheduler.
This race leads to use-after-free of a "struct pid".
It is probably somewhat hard to hit because process A has to pass
through a synchronize_rcu() operation while process B is between
mutex_unlock() and get_pid().
Fix it by ensuring that by the time a pointer to the current task's pid
is stored in the file, an extra reference to the pid has been taken.
This fix also removes the condition for synchronize_rcu(); I think
that optimization is unnecessary complexity, since in that case we
would usually have bailed out on the lockless check above.

No victim process needs to act or be in any particular state.\nS:U - The use-after-free corrupts kernel slab memory within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed by the flaw itself.\nC:H - The freed `struct pid` can be reallocated with attacker-sprayed data and is subsequently read by `put_pid()` (`pid-\u003enumbers[pid-\u003elevel].ns`) and by pid-lookup paths, giving a use-after-free read primitive that can be leveraged to disclose arbitrary kernel memory.\nI:H - `get_pid()` performs a refcount increment into freed slab memory, and the stale reference later drives `refcount_dec_and_test()` plus `kmem_cache_free()` on a possibly reallocated object \u2014 a UAF write and double-free on a core object, which is a well-established primitive for heap grooming and local privilege escalation.\nA:H - The use-after-free on `struct pid` corrupts the pid slab cache and triggers refcount underflow warnings, invalid frees, and kernel oops/panic, and the race can be re-triggered repeatedly by an unprivileged process."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: E-switch, Create ingress ACL when needed
Currently, ingress acl is used for three features. It is created only
when vport metadata match and prio tag are enabled. But active-backup
lag mode also uses it. It is independent of vport metadata match and
prio tag. And vport metadata match can be disabled using the
following devlink command:
# devlink dev param set pci/0000:08:00.0 name esw_port_metadata \
value false cmode runtime
If ingress acl is not created, will hit panic when creating drop rule
for active-backup lag mode. If always create it, there will be about
5% performance degradation.
Fix it by creating ingress acl when needed. If esw_port_metadata is
true, ingress acl exists, then create drop rule using existing
ingress acl. If esw_port_metadata is false, create ingress acl and
then create drop rule.

Summary
In the Linux kernel, the following vulnerability has been resolved:
binder: fix UAF caused by offsets overwrite
Binder objects are processed and copied individually into the target
buffer during transactions. Any raw data in-between these objects is
copied as well. However, this raw data copy lacks an out-of-bounds
check. If the raw data exceeds the data section size then the copy
overwrites the offsets section. This eventually triggers an error that
attempts to unwind the processed objects. However, at this point the
offsets used to index these objects are now corrupted.
Unwinding with corrupted offsets can result in decrements of arbitrary
nodes and lead to their premature release. Other users of such nodes are
left with a dangling pointer triggering a use-after-free. This issue is
made evident by the following KASAN report (trimmed):
==================================================================

To avoid this issue, let's check that the raw data copy is within the
boundaries of the data section.

[...]
This crash happens every time when running sockmap_skb_verdict_shutdown
subtest in sockmap_basic.
This crash is because a NULL pointer is passed to page_address() in the
sk_msg_recvmsg(). Due to the different implementations depending on the
architecture, page_address(NULL) will trigger a panic on Loongarch
platform but not on x86 platform. So this bug was hidden on x86 platform
for a while, but now it is exposed on Loongarch platform. The root cause
is that a zero length skb (skb->len == 0) was put on the queue.
This zero length skb is a TCP FIN packet, which was sent by shutdown(),
invoked in test_sockmap_skb_verdict_shutdown():
shutdown(p1, SHUT_WR);
In this case, in sk_psock_skb_ingress_enqueue(), num_sge is zero, and no
page is put to this sge (see sg_set_page in sg_set_page), but this empty
sge is queued into ingress_msg list.
And in sk_msg_recvmsg(), this empty sge is used, and a NULL page is got by
sg_page(sge). Pass this NULL page to copy_page_to_iter(), which passes it
to kmap_local_page() and to page_address(), then kernel panics.
To solve this, we should skip this zero length skb. So in sk_msg_recvmsg(),
if copy is zero, that means it's a zero length skb, skip invoking
copy_page_to_iter(). We are using the EFAULT return triggered by
copy_page_to_iter to check for is_fin in tcp_bpf.c.

Both sides of the condition are under attacker control, so this is not a state beyond their influence.\nPR:L - A completely unprivileged user reaches `bpf_int_jit_compile()` through `sk_attach_filter()` on any socket or through `seccomp()` under NO_NEW_PRIVS \u2014 no CAP_BPF, no CAP_NET_ADMIN, and no user namespace required. Only a basic local account is needed.\nUI:N - The attacker attaches the filter and triggers execution entirely from their own process. No victim action, mount, or file open is involved.\nS:U - The unprotected memory and the resulting crash or code injection are all within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - A failed lock leaves a writable, executable kernel page containing attacker-influenced JIT output, which is a direct kernel code-injection primitive when paired with any write; injected code yields arbitrary kernel memory disclosure. The loss of the read-only guarantee on executable memory is a full compromise of confidentiality in the worst case.\nI:H - On arm32 the JIT buffer stays RWX with attacker-chosen immediates embedded in it \u2014 precisely the JIT-spray/control-flow-hijack scenario that `bpf_jit_binary_lock_ro()` exists to prevent, permitting arbitrary kernel code execution. Kernel executable memory silently remaining writable is an integrity failure of the highest order.\nA:H - On s390 and x86-32 the buffer is allocated NX and only becomes executable via `set_memory_rox()`; on failure the JIT still sets `bpf_func`/`jited = 1`, so the first run of the filter faults on an instruction fetch from a non-executable page and oopses the kernel. An unprivileged user can repeat this to panic the system."

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: qgroup: fix quota root leak after quota disable failure
If during the quota disable we fail when cleaning the quota tree or when
deleting the root from the root tree, we jump to the 'out' label without
ever dropping the reference on the quota root, resulting in a leak of the
root since fs_info->quota_root is no longer pointing to the root (we have
set it to NULL just before those steps).
Fix this by always doing a btrfs_put_root() call under the 'out' label.
This is a problem that exists since qgroups were first added in 2012 by
commit bed92eae26cc ("Btrfs: qgroup implementation and prototypes"), but
back then we missed a kfree on the quota root and free_extent_buffer()
calls on its root and commit root nodes, since back then roots were not
yet reference counted.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ata: libata-core: Fix null pointer dereference on error
If the ata_port_alloc() call in ata_host_alloc() fails,
ata_host_release() will get called.
However, the code in ata_host_release() tries to free ata_port struct
members unconditionally, which can lead to the following:

Summary
In the Linux kernel, the following vulnerability has been resolved:
Revert "sched/fair: Make sure to try to detach at least one movable task"
This reverts commit b0defa7ae03ecf91b8bfd10ede430cff12fcbd06.
b0defa7ae03ec changed the load balancing logic to ignore env.max_loop if
all tasks examined to that point were pinned. The goal of the patch was
to make it more likely to be able to detach a task buried in a long list
of pinned tasks. However, this has the unfortunate side effect of
creating an O(n) iteration in detach_tasks(), as we now must fully
iterate every task on a cpu if all or most are pinned. Since this load
balance code is done with rq lock held, and often in softirq context, it
is very easy to trigger hard lockups. We observed such hard lockups with
a user who affined O(10k) threads to a single cpu.
When I discussed this with Vincent he initially suggested that we keep
the limit on the number of tasks to detach, but increase the number of
tasks we can search. However, after some back and forth on the mailing
list, he recommended we instead revert the original patch, as it seems
likely no one was actually getting hit by the original issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau/dispnv04: fix null pointer dereference in nv17_tv_get_ld_modes
In nv17_tv_get_ld_modes(), the return value of drm_mode_duplicate() is
assigned to mode, which will lead to a possible NULL pointer dereference
on failure of drm_mode_duplicate(). Add a check to avoid npd.

Summary
In the Linux kernel, the following vulnerability has been resolved:
lib: objagg: Fix general protection fault
The library supports aggregation of objects into other objects only if
the parent object does not have a parent itself. That is, nesting is not
supported.
Aggregation happens in two cases: Without and with hints, where hints
are a pre-computed recommendation on how to aggregate the provided
objects.
Nesting is not possible in the first case due to a check that prevents
it, but in the second case there is no check because the assumption is
that nesting cannot happen when creating objects based on hints. The
violation of this assumption leads to various warnings and eventually to
a general protection fault [1].
Before fixing the root cause, error out when nesting happens and warn.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc: Avoid nmi_enter/nmi_exit in real mode interrupt.
nmi_enter()/nmi_exit() touches per cpu variables which can lead to kernel
crash when invoked during real mode interrupt handling (e.g. early HMI/MCE
interrupt handler) if percpu allocation comes from vmalloc area.
Early HMI/MCE handlers are called through DEFINE_INTERRUPT_HANDLER_NMI()
wrapper which invokes nmi_enter/nmi_exit calls. We don't see any issue when
percpu allocation is from the embedded first chunk. However with
CONFIG_NEED_PER_CPU_PAGE_FIRST_CHUNK enabled there are chances where percpu
allocation can come from the vmalloc area.
With kernel command line "percpu_alloc=page" we can force percpu allocation
to come from vmalloc area and can see kernel crash in machine_check_early:
[ 1.215714] NIP [c000000000e49eb4] rcu_nmi_enter+0x24/0x110
[ 1.215717] LR [c0000000000461a0] machine_check_early+0xf0/0x2c0
[ 1.215719] --- interrupt: 200
[ 1.215720] [c000000fffd73180] [0000000000000000] 0x0 (unreliable)
[ 1.215722] [c000000fffd731b0] [0000000000000000] 0x0
[ 1.215724] [c000000fffd73210] [c000000000008364] machine_check_early_common+0x134/0x1f8
Fix this by avoiding use of nmi_enter()/nmi_exit() in real mode if percpu
first chunk is not embedded.

Summary
In the Linux kernel, the following vulnerability has been resolved:
lib/generic-radix-tree.c: Fix rare race in __genradix_ptr_alloc()
If we need to increase the tree depth, allocate a new node, and then
race with another thread that increased the tree depth before us, we'll
still have a preallocated node that might be used later.
If we then use that node for a new non-root node, it'll still have a
pointer to the old root instead of being zeroed - fix this by zeroing it
in the cmpxchg failure path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gfs2: Fix potential glock use-after-free on unmount
When a DLM lockspace is released and there ares still locks in that
lockspace, DLM will unlock those locks automatically. Commit
fb6791d100d1b started exploiting this behavior to speed up filesystem
unmount: gfs2 would simply free glocks it didn't want to unlock and then
release the lockspace. This didn't take the bast callbacks for
asynchronous lock contention notifications into account, which remain
active until until a lock is unlocked or its lockspace is released.
To prevent those callbacks from accessing deallocated objects, put the
glocks that should not be unlocked on the sd_dead_glocks list, release
the lockspace, and only then free those glocks.
As an additional measure, ignore unexpected ast and bast callbacks if
the receiving glock is dead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/filemap: make MAX_PAGECACHE_ORDER acceptable to xarray
Patch series "mm/filemap: Limit page cache size to that supported by
xarray", v2.
Currently, xarray can't support arbitrary page cache size. More details
can be found from the WARN_ON() statement in xas_split_alloc(). In our
test whose code is attached below, we hit the WARN_ON() on ARM64 system
where the base page size is 64KB and huge page size is 512MB. The issue
was reported long time ago and some discussions on it can be found here
[1].
[1] https://www.spinics.net/lists/linux-xfs/msg75404.html
In order to fix the issue, we need to adjust MAX_PAGECACHE_ORDER to one
supported by xarray and avoid PMD-sized page cache if needed. The code
changes are suggested by David Hildenbrand.
PATCH[1] adjusts MAX_PAGECACHE_ORDER to that supported by xarray
PATCH[2-3] avoids PMD-sized page cache in the synchronous readahead path
PATCH[4] avoids PMD-sized page cache for shmem files if needed

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix overrunning reservations in ringbuf
The BPF ring buffer internally is implemented as a power-of-2 sized circular
buffer, with two logical and ever-increasing counters: consumer_pos is the
consumer counter to show which logical position the consumer consumed the
data, and producer_pos which is the producer counter denoting the amount of
data reserved by all producers.
Each time a record is reserved, the producer that "owns" the record will
successfully advance producer counter. In user space each time a record is
read, the consumer of the data advanced the consumer counter once it finished
processing. Both counters are stored in separate pages so that from user
space, the producer counter is read-only and the consumer counter is read-write.
One aspect that simplifies and thus speeds up the implementation of both
producers and consumers is how the data area is mapped twice contiguously
back-to-back in the virtual memory, allowing to not take any special measures
for samples that have to wrap around at the end of the circular buffer data
area, because the next page after the last data page would be first data page
again, and thus the sample will still appear completely contiguous in virtual
memory.
Each record has a struct bpf_ringbuf_hdr { u32 len; u32 pg_off; } header for
book-keeping the length and offset, and is inaccessible to the BPF program.
Helpers like bpf_ringbuf_reserve() return `(void *)hdr + BPF_RINGBUF_HDR_SZ`
for the BPF program to use. Bing-Jhong and Muhammad reported that it is however
possible to make a second allocated memory chunk overlapping with the first
chunk and as a result, the BPF program is now able to edit first chunk's
header.
For example, consider the creation of a BPF_MAP_TYPE_RINGBUF map with size
of 0x4000. Next, the consumer_pos is modified to 0x3000 /before/ a call to
bpf_ringbuf_reserve() is made. This will allocate a chunk A, which is in
[0x0,0x3008], and the BPF program is able to edit [0x8,0x3008]. Now, lets
allocate a chunk B with size 0x3000. This will succeed because consumer_pos
was edited ahead of time to pass the `new_prod_pos - cons_pos > rb->mask`
check. Chunk B will be in range [0x3008,0x6010], and the BPF program is able
to edit [0x3010,0x6010]. Due to the ring buffer memory layout mentioned
earlier, the ranges [0x0,0x4000] and [0x4000,0x8000] point to the same data
pages. This means that chunk B at [0x4000,0x4008] is chunk A's header.
bpf_ringbuf_submit() / bpf_ringbuf_discard() use the header's pg_off to then
locate the bpf_ringbuf itself via bpf_ringbuf_restore_from_rec(). Once chunk
B modified chunk A's header, then bpf_ringbuf_commit() refers to the wrong
page and could cause a crash.
Fix it by calculating the oldest pending_pos and check whether the range
from the oldest outstanding record to the newest would span beyond the ring
buffer size. If that is the case, then reject the request. We've tested with
the ring buffer benchmark in BPF selftests (./benchs/run_bench_ringbufs.sh)
before/after the fix and while it seems a bit slower on some benchmarks, it
is still not significantly enough to matter.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Fix overrunning reservations in ringbuf\n\nThe BPF ring buffer internally is implemented as a power-of-2 sized circular\nbuffer, with two logical and ever-increasing counters: consumer_pos is the\nconsumer counter to show which logical position the consumer consumed the\ndata, and producer_pos which is the producer counter denoting the amount of\ndata reserved by all producers.\n\nEach time a record is reserved, the producer that \"owns\" the record will\nsuccessfully advance producer counter. In user space each time a record is\nread, the consumer of the data advanced the consumer counter once it finished\nprocessing. Both counters are stored in separate pages so that from user\nspace, the producer counter is read-only and the consumer counter is read-write.\n\nOne aspect that simplifies and thus speeds up the implementation of both\nproducers and consumers is how the data area is mapped twice contiguously\nback-to-back in the virtual memory, allowing to not take any special measures\nfor samples that have to wrap around at the end of the circular buffer data\narea, because the next page after the last data page would be first data page\nagain, and thus the sample will still appear completely contiguous in virtual\nmemory.\n\nEach record has a struct bpf_ringbuf_hdr { u32 len; u32 pg_off; } header for\nbook-keeping the length and offset, and is inaccessible to the BPF program.\nHelpers like bpf_ringbuf_reserve() return `(void *)hdr + BPF_RINGBUF_HDR_SZ`\nfor the BPF program to use. Bing-Jhong and Muhammad reported that it is however\npossible to make a second allocated memory chunk overlapping with the first\nchunk and as a result, the BPF program is now able to edit first chunk\u0027s\nheader.\n\nFor example, consider the creation of a BPF_MAP_TYPE_RINGBUF map with size\nof 0x4000. Next, the consumer_pos is modified to 0x3000 /before/ a call to\nbpf_ringbuf_reserve() is made. This will allocate a chunk A, which is in\n[0x0,0x3008], and the BPF program is able to edit [0x8,0x3008]. Now, lets\nallocate a chunk B with size 0x3000. This will succeed because consumer_pos\nwas edited ahead of time to pass the `new_prod_pos - cons_pos \u003e rb-\u003emask`\ncheck. Chunk B will be in range [0x3008,0x6010], and the BPF program is able\nto edit [0x3010,0x6010]. Due to the ring buffer memory layout mentioned\nearlier, the ranges [0x0,0x4000] and [0x4000,0x8000] point to the same data\npages. This means that chunk B at [0x4000,0x4008] is chunk A\u0027s header.\nbpf_ringbuf_submit() / bpf_ringbuf_discard() use the header\u0027s pg_off to then\nlocate the bpf_ringbuf itself via bpf_ringbuf_restore_from_rec(). Once chunk\nB modified chunk A\u0027s header, then bpf_ringbuf_commit() refers to the wrong\npage and could cause a crash.\n\nFix it by calculating the oldest pending_pos and check whether the range\nfrom the oldest outstanding record to the newest would span beyond the ring\nbuffer size. If that is the case, then reject the request. We\u0027ve tested with\nthe ring buffer benchmark in BPF selftests (./benchs/run_bench_ringbufs.sh)\nbefore/after the fix and while it seems a bit slower on some benchmarks, it\nis still not significantly enough to matter."

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: zoned: fix use-after-free due to race with dev replace
While loading a zone's info during creation of a block group, we can race
with a device replace operation and then trigger a use-after-free on the
device that was just replaced (source device of the replace operation).
This happens because at btrfs_load_zone_info() we extract a device from
the chunk map into a local variable and then use the device while not
under the protection of the device replace rwsem. So if there's a device
replace operation happening when we extract the device and that device
is the source of the replace operation, we will trigger a use-after-free
if before we finish using the device the replace operation finishes and
frees the device.
Fix this by enlarging the critical section under the protection of the
device replace rwsem so that all uses of the device are done inside the
critical section.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tap: add missing verification for short frame
The cited commit missed to check against the validity of the frame length
in the tap_get_user_xdp() path, which could cause a corrupted skb to be
sent downstack. Even before the skb is transmitted, the
tap_get_user_xdp()-->skb_set_network_header() may assume the size is more
than ETH_HLEN. Once transmitted, this could either cause out-of-bound
access beyond the actual length, or confuse the underlayer with incorrect
or inconsistent header length in the skb metadata.
In the alternative path, tap_get_user() already prohibits short frame which
has the length less than Ethernet header size from being transmitted.
This is to drop any frame shorter than the Ethernet header size just like
how tap_get_user() does.

Data arrives via shared memory rings, not from a remote network peer, so this is local rather than network access.\nAC:L - The attacker simply posts a TX descriptor whose payload is shorter than 14 bytes and kicks the virtqueue; vhost_net_build_xdp() only rejects len \u003c sock_hlen, so the short frame reaches tap_get_user_xdp() deterministically. The XDP batch path is active in the default QEMU configuration (unlimited sndbuf), and can be retried indefinitely.\nPR:L - The attacker must be an authorized guest VM on the host, or a local user with access to /dev/vhost-net and a tap/macvtap character device \u2014 some privilege, but nothing resembling host root. No CAP_SYS_ADMIN or init-namespace root is needed to trigger the path.\nUI:N - The malformed frame is processed entirely by the vhost worker kthread as soon as the guest kicks the ring; no host administrator or victim action is involved.\nS:C - A guest VM with zero host privileges corrupts host-kernel skb state and leaks host heap contents, crossing the guest/host virtualization boundary; the impacted resources (host kernel, physical NIC path, peer macvtap interfaces belonging to other tenants) lie outside the attacking guest\u0027s security authority.\nC:H - skb-\u003eprotocol is populated from eth_hdr() bytes that were never copied from the guest, exposing uninitialized page_frag memory that can contain remnants of previously transmitted host/other-guest packets, and the sub-ETH_HLEN skb causes downstream code to read beyond the actual frame length. The resulting memory-disclosure primitive is not bounded to a trivial value.\nI:H - A corrupted skb with network_header pointing past skb-\u003etail is passed to dev_queue_xmit(), so lower-layer drivers and offload code compute header lengths that underflow to enormous unsigned values, yielding out-of-bounds accesses and DMA/copy lengths attacker-influencing kernel memory. Such skb metadata corruption is leverageable for control-flow-relevant memory corruption.\nA:H - The out-of-bounds accesses and inconsistent header offsets in downstream network drivers readily produce a kernel oops or panic on the host, and the guest can repeat the trigger at will to keep the host down."

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix state management in error path of log writing function
After commit a694291a6211 ("nilfs2: separate wait function from
nilfs_segctor_write") was applied, the log writing function
nilfs_segctor_do_construct() was able to issue I/O requests continuously
even if user data blocks were split into multiple logs across segments,
but two potential flaws were introduced in its error handling.
First, if nilfs_segctor_begin_construction() fails while creating the
second or subsequent logs, the log writing function returns without
calling nilfs_segctor_abort_construction(), so the writeback flag set on
pages/folios will remain uncleared. This causes page cache operations to
hang waiting for the writeback flag. For example,
truncate_inode_pages_final(), which is called via nilfs_evict_inode() when
an inode is evicted from memory, will hang.
Second, the NILFS_I_COLLECTED flag set on normal inodes remain uncleared.
As a result, if the next log write involves checkpoint creation, that's
fine, but if a partial log write is performed that does not, inodes with
NILFS_I_COLLECTED set are erroneously removed from the "sc_dirty_files"
list, and their data and b-tree blocks may not be written to the device,
corrupting the block mapping.
Fix these issues by uniformly calling nilfs_segctor_abort_construction()
on failure of each step in the loop in nilfs_segctor_do_construct(),
having it clean up logs and segment usages according to progress, and
correcting the conditions for calling nilfs_redirty_inodes() to ensure
that the NILFS_I_COLLECTED flag is cleared.

No network protocol handler processes remote data on this path.\nAC:L - There is no race and no memory-layout dependency; the attacker deterministically creates both required conditions by writing a file larger than one segment (forcing a second log iteration in SC_LSEG_DSYNC mode) while having exhausted the filesystem\u0027s clean segments, so nilfs_sufile_alloc() returns -ENOSPC inside the second nilfs_segctor_begin_construction(). Memory pressure (-ENOMEM from nilfs_segbuf_new) is an equally attacker-controllable alternative trigger.\nPR:L - Any unprivileged local user with write access to an already-mounted nilfs2 filesystem can reach nilfs_segctor_do_construct() via plain writes and fdatasync \u2014 no capability, ioctl, or mount privilege is checked on this path (CAP_SYS_ADMIN is only needed for the unrelated GC ioctl).\nUI:N - On a system already using nilfs2 (flash/removable media, udisks-automounted volumes) the attacker drives the entire sequence with their own file I/O and the kernel\u0027s own writeback thread. No action by a separate victim user is required.\nS:U - The stuck writeback state, the hung tasks, and the filesystem corruption are all confined to the kernel and filesystem of the same system; no VM, IOMMU, or sandbox security boundary is crossed.\nC:L - Dropping inodes from sc_dirty_files without writing their data and b-tree blocks corrupts the block mapping, so an inode\u0027s bmap can retain virtual block numbers whose DAT entries are stale or recycled by the segment cleaner, causing later reads to return blocks belonging to other users\u0027 files. The exposure is stale on-disk filesystem data the attacker cannot select, not an arbitrary kernel memory read.\nI:H - sc_dirty_files holds every dirty inode on the filesystem, not just the attacker\u0027s, so the uncleared NILFS_I_COLLECTED flag causes arbitrary inodes\u0027 data and b-tree blocks to be silently discarded while they are marked as written, corrupting the on-disk block mapping. This is persistent, unrecoverable filesystem metadata corruption with direct serious consequence \u2014 silent data loss across users and an inconsistent filesystem that can trigger nilfs_error() (forced read-only, or panic under errors=panic).\nA:H - The writeback flag left set on file-data and b-tree folios is never cleared, so folio_wait_writeback() callers \u2014 truncate_inode_pages_final() during inode eviction, sync/syncfs, umount, rewrite of the same page, and page reclaim/migration \u2014 block in uninterruptible sleep permanently, producing unkillable D-state tasks, hung-task warnings, unreclaimable pinned memory, and a system shutdown that never completes."

Summary
In the Linux kernel, the following vulnerability has been resolved:
closures: Change BUG_ON() to WARN_ON()
If a BUG_ON() can be hit in the wild, it shouldn't be a BUG_ON()
For reference, this has popped up once in the CI, and we'll need more
info to debug it:

</TASK>
And it also pinned it down to commit b5357cb268c4 ("btrfs: qgroup: do not
check qgroup inherit if qgroup is disabled").
[CAUSE]
That offending commit skips the whole qgroup inherit check if qgroup is
not enabled.
But that also skips the very basic checks like
num_ref_copies/num_excl_copies and the structure size checks.
Meaning if a qgroup enable/disable race is happening at the background,
and we pass a btrfs_qgroup_inherit structure when the qgroup is
disabled, the check would be completely skipped.
Then at the time of transaction commitment, qgroup is re-enabled and
btrfs_qgroup_inherit() is going to use the incorrect structure and
causing the above KASAN error.
[FIX]
Make btrfs_qgroup_check_inherit() only skip the source qgroup checks.
So that even if invalid btrfs_qgroup_inherit structure is passed in, we
can still reject invalid ones no matter if qgroup is enabled or not.
Furthermore we do already have an extra safety inside
btrfs_qgroup_inherit(), which would just ignore invalid qgroup sources,
so even if we only skip the qgroup source check we're still safe.

"value": "AV:L - The vulnerability is reached through the BTRFS_IOC_SNAP_CREATE_V2/BTRFS_IOC_SUBVOL_CREATE_V2 ioctls on a mounted btrfs filesystem, requiring a local account on the system. There is no network-facing path to this code.\nAC:L - The attacker fully controls the malformed btrfs_qgroup_inherit structure and the long side of the check-to-use window, which spans an entire transaction commit and can be stretched with I/O load, and the snapshot ioctl can be replayed in a tight loop indefinitely until the window is hit. No memory layout or timing condition outside the attacker\u0027s influence is needed to trigger the out-of-bounds access itself.\nPR:L - Issuing the vulnerable ioctl requires no capability at all - subvolume creation is explicitly unrestricted and snapshot creation only requires ownership of one\u0027s own subvolume, so an ordinary unprivileged user with write access to a btrfs directory suffices. The concurrent qgroup enable is background system activity (snapper, container/LXD tooling), not a privilege the attacker must hold.\nUI:N - The attack is driven entirely by the attacker\u0027s own ioctl calls against an already-mounted btrfs filesystem. No victim action is required.\nS:U - The out-of-bounds access corrupts kernel slab memory within the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The loop performs an unbounded sequential out-of-bounds read of kernel slab memory past a buffer of attacker-chosen size, with the read length controlled by the unvalidated num_qgroups/num_ref_copies/num_excl_copies fields. Read values that match existing qgroup IDs escape zeroing and are propagated into qgroup relations, and the corrupted adjacent objects provide a route to broader kernel memory disclosure.\nI:H - The same loop performs an out-of-bounds write (*i_qgroups = 0ULL) into memory following the slab object, with both the target slab size class (via vol_args-\u003esize) and the corruption length attacker-controlled. Zeroing pointers, refcounts, and length fields in groomed neighbouring objects is a well-established path to use-after-free and privilege escalation.\nA:H - Syzbot reproduced this as a KASAN slab-out-of-bounds, and a large attacker-supplied count walks the loop into unmapped memory or destroys adjacent kernel structures, producing an oops or panic. The corruption also occurs during transaction commit, where failures escalate to a filesystem abort."

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_buffers: Fix memory corruptions on Spectrum-4 systems
The following two shared buffer operations make use of the Shared Buffer
Status Register (SBSR):
# devlink sb occupancy snapshot pci/0000:01:00.0
# devlink sb occupancy clearmax pci/0000:01:00.0
The register has two masks of 256 bits to denote on which ingress /
egress ports the register should operate on. Spectrum-4 has more than
256 ports, so the register was extended by cited commit with a new
'port_page' field.
However, when filling the register's payload, the driver specifies the
ports as absolute numbers and not relative to the first port of the port
page, resulting in memory corruptions [1].
Fix by specifying the ports relative to the first port of the port page.
[1]

Summary
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Fix garbage collector racing against connect()
Garbage collector does not take into account the risk of embryo getting
enqueued during the garbage collection. If such embryo has a peer that
carries SCM_RIGHTS, two consecutive passes of scan_children() may see a
different set of children. Leading to an incorrectly elevated inflight
count, and then a dangling pointer within the gc_inflight_list.
sockets are AF_UNIX/SOCK_STREAM
S is an unconnected socket
L is a listening in-flight socket bound to addr, not in fdtable
V's fd will be passed via sendmsg(), gets inflight count bumped
connect(S, addr) sendmsg(S, [V]); close(V) __unix_gc()
---------------- ------------------------- -----------
NS = unix_create1()
skb1 = sock_wmalloc(NS)
L = unix_find_other(addr)
unix_state_lock(L)
unix_peer(S) = NS
// V count=1 inflight=0
NS = unix_peer(S)
skb2 = sock_alloc()
skb_queue_tail(NS, skb2[V])
// V became in-flight
// V count=2 inflight=1
close(V)
// V count=1 inflight=1
// GC candidate condition met
for u in gc_inflight_list:
if (total_refs == inflight_refs)
add u to gc_candidates
// gc_candidates={L, V}
for u in gc_candidates:
scan_children(u, dec_inflight)
// embryo (skb1) was not
// reachable from L yet, so V's
// inflight remains unchanged
__skb_queue_tail(L, skb1)
unix_state_unlock(L)
for u in gc_candidates:
if (u.inflight)
scan_children(u, inc_inflight_move_tail)
// V count=1 inflight=2 (!)
If there is a GC-candidate listening socket, lock/unlock its state. This
makes GC wait until the end of any ongoing connect() to that socket. After
flipping the lock, a possibly SCM-laden embryo is already enqueued. And if
there is another embryo coming, it can not possibly carry SCM_RIGHTS. At
this point, unix_inflight() can not happen because unix_gc_lock is already
taken. Inflight graph remains unaffected.

Consistent with other qla2xxx fabric-driven NULL-deref CVEs in this driver (e.g. CVE-2025-71236), the remote FC peer that drives discovery makes this network-reachable.\nAC:L - Both sides of the race are discovery paths an attacker can drive repeatedly by generating link bounces/RSCNs and port logins, forcing concurrent `qla_nvme_register_hba()` entry from the DPC thread and the fcport workqueue. The race was hit spontaneously on ordinary driver load in the field, showing the window is wide and requires no special conditions.\nPR:N - No credentials are checked anywhere on the path \u2014 standard Fibre Channel fabric login and RSCN processing is unauthenticated by default (FC-SP/EDIF is opt-in and rarely deployed), and the crashing code runs in kernel worker context with no privilege gate.\nUI:N - The registration path is triggered automatically by fabric discovery and driver initialization; no administrator or user action is needed beyond the system having an NVMe-FC-capable qla2xxx HBA attached to the fabric.\nS:U - The NULL dereference oopses inside the kernel that owns the driver; no VM, IOMMU, or sandbox boundary is crossed and the impact stays within the same security authority.\nC:N - The fault is a dereference of a NULL `nvme_fc_local_port` at fixed offset 0x70, an address below `mmap_min_addr` that cannot be mapped or populated by an attacker, so no kernel memory contents are disclosed.\nI:N - The access is `kref_get_unless_zero()` on an unmappable NULL-page address, which faults before any state is modified; there is no out-of-bounds write, freed-object reuse, or type confusion to leverage for corruption.\nA:H - The dereference produces a kernel oops in `events_unbound`/`qla_register_fcport_fn`, killing the worker, aborting driver load, and leaving the NVMe-FC storage path unusable \u2014 a full panic on `panic_on_oops` systems."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Skip wbscl_set_scaler_filter if filter is null
Callers can pass null in filter (i.e. from returned from the function
wbscl_get_filter_coeffs_16p) and a null check is added to ensure that is
not the case.
This fixes 4 NULL_RETURNS issues reported by Coverity.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: core_linecards: Fix double memory deallocation in case of invalid INI file
In case of invalid INI file mlxsw_linecard_types_init() deallocates memory
but doesn't reset pointer to NULL and returns 0. In case of any error
occurred after mlxsw_linecard_types_init() call, mlxsw_linecards_init()
calls mlxsw_linecard_types_fini() which performs memory deallocation again.
Add pointer reset to NULL.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fuse: Initialize beyond-EOF page contents before setting uptodate
fuse_notify_store(), unlike fuse_do_readpage(), does not enable page
zeroing (because it can be used to change partial page contents).
So fuse_notify_store() must be more careful to fully initialize page
contents (including parts of the page that are beyond end-of-file)
before marking the page uptodate.
The current code can leave beyond-EOF page contents uninitialized, which
makes these uninitialized page contents visible to userspace via mmap().
This is an information leak, but only affects systems which do not
enable init-on-alloc (via CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y or the
corresponding kernel command line parameter).

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: unconditionally flush pending work before notifier
syzbot reports:
KASAN: slab-uaf in nft_ctx_update include/net/netfilter/nf_tables.h:1831
KASAN: slab-uaf in nft_commit_release net/netfilter/nf_tables_api.c:9530
KASAN: slab-uaf int nf_tables_trans_destroy_work+0x152b/0x1750 net/netfilter/nf_tables_api.c:9597
Read of size 2 at addr ffff88802b0051c4 by task kworker/1:1/45
[..]
Workqueue: events nf_tables_trans_destroy_work
Call Trace:
nft_ctx_update include/net/netfilter/nf_tables.h:1831 [inline]
nft_commit_release net/netfilter/nf_tables_api.c:9530 [inline]
nf_tables_trans_destroy_work+0x152b/0x1750 net/netfilter/nf_tables_api.c:9597
Problem is that the notifier does a conditional flush, but its possible
that the table-to-be-removed is still referenced by transactions being
processed by the worker, so we need to flush unconditionally.
We could make the flush_work depend on whether we found a table to delete
in nf-next to avoid the flush for most cases.
AFAICS this problem is only exposed in nf-next, with
commit e169285f8c56 ("netfilter: nf_tables: do not store nft_ctx in transaction objects"),
with this commit applied there is an unconditional fetch of
table->family which is whats triggering the above splat.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: vmalloc: check if a hash-index is in cpu_possible_mask
The problem is that there are systems where cpu_possible_mask has gaps
between set CPUs, for example SPARC. In this scenario addr_to_vb_xa()
hash function can return an index which accesses to not-possible and not
setup CPU area using per_cpu() macro. This results in an oops on SPARC.
A per-cpu vmap_block_queue is also used as hash table, incorrectly
assuming the cpu_possible_mask has no gaps. Fix it by adjusting an index
to a next possible CPU.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: Fix a memory corruption issue
A few lines above, space is kzalloc()'ed for:
sizeof(struct iwl_nvm_data) +
sizeof(struct ieee80211_channel) +
sizeof(struct ieee80211_rate)
'mvm->nvm_data' is a 'struct iwl_nvm_data', so it is fine.
At the end of this structure, there is the 'channels' flex array.
Each element is of type 'struct ieee80211_channel'.
So only 1 element is allocated in this array.
When doing:
mvm->nvm_data->bands[0].channels = mvm->nvm_data->channels;
We point at the first element of the 'channels' flex array.
So this is fine.
However, when doing:
mvm->nvm_data->bands[0].bitrates =
(void *)((u8 *)mvm->nvm_data->channels + 1);
because of the "(u8 *)" cast, we add only 1 to the address of the beginning
of the flex array.
It is likely that we want point at the 'struct ieee80211_rate' allocated
just after.
Remove the spurious casting so that the pointer arithmetic works as
expected.

Summary
In the Linux kernel, the following vulnerability has been resolved:
misc: fastrpc: Fix memory leak in audio daemon attach operation
Audio PD daemon send the name as part of the init IOCTL call. This
name needs to be copied to kernel for which memory is allocated.
This memory is never freed which might result in memory leak. Free
the memory when it is not needed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cachefiles: add missing lock protection when polling
Add missing lock protection in poll routine when iterating xarray,
otherwise:
Even with RCU read lock held, only the slot of the radix tree is
ensured to be pinned there, while the data structure (e.g. struct
cachefiles_req) stored in the slot has no such guarantee. The poll
routine will iterate the radix tree and dereference cachefiles_req
accordingly. Thus RCU read lock is not adequate in this case and
spinlock is needed here.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gpio: pca953x: fix pca953x_irq_bus_sync_unlock race
Ensure that `i2c_lock' is held when setting interrupt latch and mask in
pca953x_irq_bus_sync_unlock() in order to avoid races.
The other (non-probe) call site pca953x_gpio_set_multiple() ensures the
lock is held before calling pca953x_write_regs().
The problem occurred when a request raced against irq_bus_sync_unlock()
approximately once per thousand reboots on an i.MX8MP based system.
* Normal case
0-0022: write register AI|3a {03,02,00,00,01} Input latch P0
0-0022: write register AI|49 {fc,fd,ff,ff,fe} Interrupt mask P0

0-0022: write register AI|12 {fc,00,00,00,00} Config P3
* Race case
0-0022: write register AI|08 {ff,00,00,00,00} Output P3
0-0022: write register AI|08 {03,02,00,00,01} *** Wrong register ***
0-0022: write register AI|12 {fc,00,00,00,00} Config P3

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix adding block group to a reclaim list and the unused list during reclaim
There is a potential parallel list adding for retrying in
btrfs_reclaim_bgs_work and adding to the unused list. Since the block
group is removed from the reclaim list and it is on a relocation work,
it can be added into the unused list in parallel. When that happens,
adding it to the reclaim list will corrupt the list head and trigger
list corruption like below.
Fix it by taking fs_info->unused_bgs_lock.

[177.843][T2585409] btrfs_delete_unused_bgs+0x3d9/0x14c0 [btrfs]
There is a similar retry_list code in btrfs_delete_unused_bgs(), but it is
safe, AFAICS. Since the block group was in the unused list, the used bytes
should be 0 when it was added to the unused list. Then, it checks
block_group->{used,reserved,pinned} are still 0 under the
block_group->lock. So, they should be still eligible for the unused list,
not the reclaim list.
The reason it is safe there it's because because we're holding
space_info->groups_sem in write mode.
That means no other task can allocate from the block group, so while we
are at deleted_unused_bgs() it's not possible for other tasks to
allocate and deallocate extents from the block group, so it can't be
added to the unused list or the reclaim list by anyone else.
The bug can be reproduced by btrfs/166 after a few rounds. In practice
this can be hit when relocation cannot find more chunk space and ends
with ENOSPC.

Summary
In the Linux kernel, the following vulnerability has been resolved:
watchdog: cpu5wdt.c: Fix use-after-free bug caused by cpu5wdt_trigger
When the cpu5wdt module is removing, the origin code uses del_timer() to
de-activate the timer. If the timer handler is running, del_timer() could
not stop it and will return directly. If the port region is released by
release_region() and then the timer handler cpu5wdt_trigger() calls outb()
to write into the region that is released, the use-after-free bug will
happen.
Change del_timer() to timer_shutdown_sync() in order that the timer handler
could be finished before the port region is released.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: discard write access to the directory open
may_open() does not allow a directory to be opened with the write access.
However, some writing flags set by client result in adding write access
on server, making ksmbd incompatible with FUSE file system. Simply, let's
discard the write access when opening a directory.
list_add corruption. next is NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
filelock: Remove locks reliably when fcntl/close race is detected
When fcntl_setlk() races with close(), it removes the created lock with
do_lock_file_wait().
However, LSMs can allow the first do_lock_file_wait() that created the lock
while denying the second do_lock_file_wait() that tries to remove the lock.
Separately, posix_lock_file() could also fail to
remove a lock due to GFP_KERNEL allocation failure (when splitting a range
in the middle).
After the bug has been triggered, use-after-free reads will occur in
lock_get_status() when userspace reads /proc/locks. This can likely be used
to read arbitrary kernel memory, but can't corrupt kernel memory.
Fix it by calling locks_remove_posix() instead, which is designed to
reliably get rid of POSIX locks associated with the given file and
files_struct and is also used by filp_flush().

The failure of the recovery unlock is likewise attacker-inducible, either via an LSM policy asymmetry or by forcing the `GFP_KERNEL` allocation failure in the mid-range split path under attacker-generated memory pressure.\nPR:L - Any unprivileged local user can call `fcntl()` on a file it can open and read the world-readable `/proc/locks` (confirmed mode `-r--r--r--`); no capability, user-namespace, or mount privilege is checked anywhere along the path.\nUI:N - The attacker performs every step itself \u2014 creating the lock, racing the close, and reading `/proc/locks` \u2014 with no action required from any other user or process.\nS:U - The dangling `file_lock` and the resulting reads stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `lock_get_status()` dereferences the freed `struct file` (`flc-\u003eflc_file-\u003ef_inode`) and prints `inode-\u003ei_sb-\u003es_dev` and `inode-\u003ei_ino` to userspace, giving a chosen-address read primitive once the freed slot is groomed \u2014 the fix author states this \"can likely be used to read arbitrary kernel memory.\"\nI:H - The use-after-free leaves permanently corrupted kernel lock state \u2014 a `file_lock` with dangling `flc_file` and `flc_owner` that can never be released, so a recycled `files_struct` at the same address grants an unrelated (possibly higher-privileged) process spurious ownership of the stale lock. Combined with the arbitrary-read primitive that defeats KASLR and exposes credentials/keys, the condition is leverageable toward privilege escalation.\nA:H - Reading `/proc/locks` after the freed page is reclaimed oopses the kernel, and the pre-fix `WARN_ON_ONCE()` panics outright on the `panic_on_warn` configurations common in hardened and Android deployments. The permanently un-releasable stale lock also blocks any other process waiting via `F_SETLKW` on that inode indefinitely."

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: PPC: Book3S HV: Prevent UAF in kvm_spapr_tce_attach_iommu_group()
Al reported a possible use-after-free (UAF) in kvm_spapr_tce_attach_iommu_group().
It looks up `stt` from tablefd, but then continues to use it after doing
fdput() on the returned fd. After the fdput() the tablefd is free to be
closed by another thread. The close calls kvm_spapr_tce_release() and
then release_spapr_tce_table() (via call_rcu()) which frees `stt`.
Although there are calls to rcu_read_lock() in
kvm_spapr_tce_attach_iommu_group() they are not sufficient to prevent
the UAF, because `stt` is used outside the locked regions.
With an artifcial delay after the fdput() and a userspace program which
triggers the race, KASAN detects the UAF:
BUG: KASAN: slab-use-after-free in kvm_spapr_tce_attach_iommu_group+0x298/0x720 [kvm]

Fix it by delaying the fdput() until `stt` is no longer in use, which
is effectively the entire function. To keep the patch minimal add a call
to fdput() at each of the existing return paths. Future work can convert
the function to goto or __cleanup style cleanup.
With the fix in place the test case no longer triggers the UAF.

No remote or adjacent-network input reaches this path.\nAC:L - The attacker owns both sides of the race \u2014 one thread issues the ioctl while another calls `close(tablefd)` \u2014 and the window between `fdput()` and the uses of `stt` contains a sleepable `kzalloc(GFP_KERNEL)` that can be stretched arbitrarily under attacker-induced memory pressure. Failed attempts merely return an errno, so the race can be retried indefinitely, and the attacker also chooses the slab bucket via `KVM_CREATE_SPAPR_TCE_64`\u0027s `size` argument.\nPR:L - No `capable()` or `CAP_*` check exists anywhere along the path in `book3s_64_vio.c` or `virt/kvm/vfio.c`; the attacker only needs file access to /dev/kvm and a VFIO group node, which libvirt routinely grants to the unprivileged QEMU user in the standard PPC64 device-passthrough deployment. A compromised VMM process that has escaped a guest into QEMU holds exactly these descriptors, so real root is not required.\nUI:N - Both the ioctl and the racing `close()` are performed entirely by the attacker\u0027s own threads. No administrator or victim action is involved.\nS:U - The attacker is a host-local userspace process and the corrupted memory is host kernel heap, so the vulnerable and impacted components share one security authority. A guest cannot reach `kvm_vfio_set_attr`, so this is not a guest-to-host escape.\nC:H - The freed `stt` is read after free (`page_shift`, `offset`, `size`), and the `next-\u003eprev = new` write derived from freed-memory contents gives an arbitrary kernel-write primitive that is readily converted into arbitrary kernel-memory disclosure. Attacker-controlled slab-bucket selection makes the reallocation reliable enough to build a read primitive.\nI:H - `list_add_rcu(\u0026stit-\u003enext, \u0026stt-\u003eiommu_tables)` writes into the freed object and additionally performs `next-\u003eprev = new` where `next` is loaded from attacker-reallocated memory, yielding a write of a kernel heap pointer to an arbitrary address. With `__list_add_valid()` a no-op on default configs, this is a classic path to control-flow hijack and privilege escalation.\nA:H - The slab use-after-free corrupts the kernel heap and the wild `next-\u003eprev` store into an unrelated address readily produces an oops or panic; on `CONFIG_LIST_HARDENED` kernels the corrupted list triggers a BUG. The attacker can repeat the trigger at will to keep the host down."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: check n_ssids before accessing the ssids
In some versions of cfg80211, the ssids poinet might be a valid one even
though n_ssids is 0. Accessing the pointer in this case will cuase an
out-of-bound access. Fix this by checking n_ssids first.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dma: fix call order in dmam_free_coherent
dmam_free_coherent() frees a DMA allocation, which makes the
freed vaddr available for reuse, then calls devres_destroy()
to remove and free the data structure used to track the DMA
allocation. Between the two calls, it is possible for a
concurrent task to make an allocation with the same vaddr
and add it to the devres list.
If this happens, there will be two entries in the devres list
with the same vaddr and devres_destroy() can free the wrong
entry, triggering the WARN_ON() in dmam_match.
Fix by destroying the devres entry before freeing the DMA
allocation.

No remote peer data or packet-processing path drives it.\nAC:L - The attacker controls both sides of the race \u2014 two threads hammering alloc and free on the same `struct device` \u2014 and can retry indefinitely, while the LIFO behaviour of the page allocator makes the freed vaddr very likely to be handed straight back to the concurrent allocation. Nothing required is outside the attacker\u0027s influence.\nPR:L - An ordinary unprivileged local user with access to the relevant device node can drive it: `sprd_pcm_open()`/`sprd_pcm_close()` do `dmam_alloc_coherent()`/`dmam_free_coherent()` on the shared `component-\u003edev` for every PCM open/close, and `/dev/fw*` ioctls trigger the FireWire config-ROM alloc while the bus-reset work item frees concurrently. No capability or root is needed on those paths.\nUI:N - The attacker\u0027s own threads create the race entirely; no victim action, mount, or file open by another user is required.\nS:U - The corrupted devres list, the DMA allocator state, and the resulting freed memory all belong to the kernel itself, so the impact stays within the vulnerable component\u0027s security authority.\nC:H - The stale devres entry causes `dma_free_attrs()` on a live buffer at driver detach, so the pages are recycled into arbitrary kernel objects while the original owner and the device still read them, yielding an arbitrary kernel-memory disclosure primitive.\nI:H - The wrong-entry destruction produces a double-free/UAF of DMA-coherent memory with a mismatched size and dma_handle, leaving a device with a stale IOVA mapping and the allocator writing into recycled pages \u2014 a heap-corruption and arbitrary-write primitive suitable for control-flow hijack.\nA:H - The immediate observable effect is the `WARN_ON()` in `dmam_match()`/`dmam_free_coherent()`, which panics the box under `panic_on_warn`, and the subsequent DMA double-free reliably oopses the kernel."

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: avoid too many retransmit packets
If a TCP socket is using TCP_USER_TIMEOUT, and the other peer
retracted its window to zero, tcp_retransmit_timer() can
retransmit a packet every two jiffies (2 ms for HZ=1000),
for about 4 minutes after TCP_USER_TIMEOUT has 'expired'.
The fix is to make sure tcp_rtx_probe0_timed_out() takes
icsk->icsk_user_timeout into account.
Before blamed commit, the socket would not timeout after
icsk->icsk_user_timeout, but would use standard exponential
backoff for the retransmits.
Also worth noting that before commit e89688e3e978 ("net: tcp:
fix unexcepted socket die when snd_wnd is 0"), the issue
would last 2 minutes instead of 4.

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: cs_dsp: Prevent buffer overrun when processing V2 alg headers
Check that all fields of a V2 algorithm header fit into the available
firmware data buffer.
The wmfw V2 format introduced variable-length strings in the algorithm
block header. This means the overall header length is variable, and the
position of most fields varies depending on the length of the string
fields. Each field must be checked to ensure that it does not overflow
the firmware data buffer.
As this ia bugfix patch, the fixes avoid making any significant change to
the existing code. This makes it easier to review and less likely to
introduce new bugs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
udp: Set SOCK_RCU_FREE earlier in udp_lib_get_port().
syzkaller triggered the warning [0] in udp_v4_early_demux().
In udp_v[46]_early_demux() and sk_lookup(), we do not touch the refcount
of the looked-up sk and use sock_pfree() as skb->destructor, so we check
SOCK_RCU_FREE to ensure that the sk is safe to access during the RCU grace
period.
Currently, SOCK_RCU_FREE is flagged for a bound socket after being put
into the hash table. Moreover, the SOCK_RCU_FREE check is done too early
in udp_v[46]_early_demux() and sk_lookup(), so there could be a small race
window:
CPU1 CPU2
---- ----
udp_v4_early_demux() udp_lib_get_port()
| |- hlist_add_head_rcu()
|- sk = __udp4_lib_demux_lookup() |
|- DEBUG_NET_WARN_ON_ONCE(sk_is_refcounted(sk));
`- sock_set_flag(sk, SOCK_RCU_FREE)
We had the same bug in TCP and fixed it in commit 871019b22d1b ("net:
set SOCK_RCU_FREE before inserting socket into hashtable").
Let's apply the same fix for UDP.

"value": "AV:L - The racing writer side is `udp_lib_get_port()`, reached only through a local `bind()`/`connect()` syscall on a UDP socket, and the reader side needs a packet on a dst-less receive path (tun/veth), which the attacker creates locally in their own netns. A remote peer sending UDP packets cannot by itself put a socket into the unflagged window, so the bug is not remotely reachable.\nAC:L - The attacker owns both halves of the race \u2014 a thread loop calling `bind()`/`connect()` on UDP sockets and a concurrent injector feeding matching packets through tun/veth \u2014 and can widen the window by contending `hslot2-\u003elock` and by running massively in parallel across CPUs. Per the race guidance, an attacker-created race is Low complexity.\nPR:L - Binding UDP sockets requires no privilege at all, and the packet-injection side (tun/veth creation) is obtained by any unprivileged user via `unshare -Urn`, where CAP_NET_ADMIN is granted in the new user namespace. No real root or init-namespace capability is needed.\nUI:N - The attacker performs every step \u2014 socket binding, device setup, and packet injection \u2014 with no action required from any other user or administrator.\nS:U - The refcount underflow, use-after-free, and any resulting panic all occur in the kernel of the same host under the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `skb_steal_sock()` reading a stale-clear `SOCK_RCU_FREE` yields `refcounted == true`, so `udp_rcv()` drops a reference it never took, freeing `struct udp_sock` while the owning fd and the hash tables still point at it. The resulting use-after-free lets an attacker refill the slab and read back kernel memory through subsequent socket operations.\nI:H - The same unbalanced `sock_put()` produces a use-after-free on a socket object containing function pointers (`sk_prot`, `sk_data_ready`, `sk_destruct`) and list heads, which is a classic heap-spray target giving arbitrary-write and control-flow-hijack primitives.\nA:H - The race trips `DEBUG_NET_WARN_ON_ONCE()` in `udp_v4_early_demux()` and the unconditional `WARN_ONCE(1, \"Found non-RCU, unreferenced socket!\")` in `sk_lookup()`, tainting the kernel and panicking outright on `panic_on_warn=1` systems; the premature socket free additionally corrupts the UDP hash lists and crashes the kernel even when not exploited further."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Fix ufshcd_abort_one racing issue
When ufshcd_abort_one is racing with the completion ISR, the completed tag
of the request's mq_hctx pointer will be set to NULL by ISR. Return
success when request is completed by ISR because ufshcd_abort_one does not
need to do anything.
The racing flow is:
Thread A
ufshcd_err_handler step 1
...
ufshcd_abort_one
ufshcd_try_to_abort_task
ufshcd_cmd_inflight(true) step 3
ufshcd_mcq_req_to_hwq
blk_mq_unique_tag
rq->mq_hctx->queue_num step 5
Thread B
ufs_mtk_mcq_intr(cq complete ISR) step 2
scsi_done
...
__blk_mq_free_request
rq->mq_hctx = NULL; step 4
Below is KE back trace.
ufshcd_try_to_abort_task: cmd at tag 41 not pending in the device.
ufshcd_try_to_abort_task: cmd at tag=41 is cleared.
Aborting tag 41 / CDB 0x28 succeeded

Summary
In the Linux kernel, the following vulnerability has been resolved:
gpio: davinci: Validate the obtained number of IRQs
Value of pdata->gpio_unbanked is taken from Device Tree. In case of broken
DT due to any error this value can be any. Without this value validation
there can be out of chips->irqs array boundaries access in
davinci_gpio_probe().
Validate the obtained nirq value so that it won't exceed the maximum
number of IRQs per bank.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
remoteproc: imx_rproc: Skip over memory region when node value is NULL
In imx_rproc_addr_init() "nph = of_count_phandle_with_args()" just counts
number of phandles. But phandles may be empty. So of_parse_phandle() in
the parsing loop (0 < a < nph) may return NULL which is later dereferenced.
Adjust this issue by adding NULL-return check.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: core: Prevent USB core invalid event buffer address access
This commit addresses an issue where the USB core could access an
invalid event buffer address during runtime suspend, potentially causing
SMMU faults and other memory issues in Exynos platforms. The problem
arises from the following sequence.
1. In dwc3_gadget_suspend, there is a chance of a timeout when
moving the USB core to the halt state after clearing the
run/stop bit by software.
2. In dwc3_core_exit, the event buffer is cleared regardless of
the USB core's status, which may lead to an SMMU faults and
other memory issues. if the USB core tries to access the event
buffer address.
To prevent this hardware quirk on Exynos platforms, this commit ensures
that the event buffer address is not cleared by software when the USB
core is active during runtime suspend by checking its status before
clearing the buffer address.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Revert "mm/writeback: fix possible divide-by-zero in wb_dirty_limits(), again"
Patch series "mm: Avoid possible overflows in dirty throttling".
Dirty throttling logic assumes dirty limits in page units fit into
32-bits. This patch series makes sure this is true (see patch 2/2 for
more details).
This patch (of 2):
This reverts commit 9319b647902cbd5cc884ac08a8a6d54ce111fc78.
The commit is broken in several ways. Firstly, the removed (u64) cast
from the multiplication will introduce a multiplication overflow on 32-bit
archs if wb_thresh * bg_thresh >= 1<<32 (which is actually common - the
default settings with 4GB of RAM will trigger this). Secondly, the
div64_u64() is unnecessarily expensive on 32-bit archs. We have
div64_ul() in case we want to be safe & cheap. Thirdly, if dirty
thresholds are larger than 1<<32 pages, then dirty balancing is going to
blow up in many other spectacular ways anyway so trying to fix one
possible overflow is just moot.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/pseries: Whitelist dtl slub object for copying to userspace
Reading the dispatch trace log from /sys/kernel/debug/powerpc/dtl/cpu-*
results in a BUG() when the config CONFIG_HARDENED_USERCOPY is enabled as
shown below.

Commit 6d07d1cd300f ("usercopy: Restrict non-usercopy caches to size 0")
requires that only whitelisted areas in slab/slub objects can be copied to
userspace when usercopy hardening is enabled using CONFIG_HARDENED_USERCOPY.
Dtl contains hypervisor dispatch events which are expected to be read by
privileged users. Hence mark this safe for user access.
Specify useroffset=0 and usersize=DISPATCH_LOG_BYTES to whitelist the
entire object.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Fix userfaultfd_api to return EINVAL as expected
Currently if we request a feature that is not set in the Kernel config we
fail silently and return all the available features. However, the man
page indicates we should return an EINVAL.
We need to fix this issue since we can end up with a Kernel warning should
a program request the feature UFFD_FEATURE_WP_UNPOPULATED on a kernel with
the config not set with this feature.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: configfs: Prevent OOB read/write in usb_string_copy()
Userspace provided string 's' could trivially have the length zero. Left
unchecked this will firstly result in an OOB read in the form
`if (str[0 - 1] == '\n') followed closely by an OOB write in the form
`str[0 - 1] = '\0'`.
There is already a validating check to catch strings that are too long.
Let's supply an additional check for invalid strings that are too short.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cxl/mem: Fix no cxl_nvd during pmem region auto-assembling
When CXL subsystem is auto-assembling a pmem region during cxl
endpoint port probing, always hit below calltrace.
BUG: kernel NULL pointer dereference, address: 0000000000000078
#PF: supervisor read access in kernel mode

The cxl_nvd of the memdev needs to be available during the pmem region
probe. Currently the cxl_nvd is registered after the endpoint port probe.
The endpoint probe, in the case of autoassembly of regions, can cause a
pmem region probe requiring the not yet available cxl_nvd. Adjust the
sequence so this dependency is met.
This requires adding a port parameter to cxl_find_nvdimm_bridge() that
can be used to query the ancestor root port. The endpoint port is not
yet available, but will share a common ancestor with its parent, so
start the query from there instead.

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:
xhci: Fix Panther point NULL pointer deref at full-speed re-enumeration
re-enumerating full-speed devices after a failed address device command
can trigger a NULL pointer dereference.
Full-speed devices may need to reconfigure the endpoint 0 Max Packet Size
value during enumeration. Usb core calls usb_ep0_reinit() in this case,
which ends up calling xhci_configure_endpoint().
On Panther point xHC the xhci_configure_endpoint() function will
additionally check and reserve bandwidth in software. Other hosts do
this in hardware
If xHC address device command fails then a new xhci_virt_device structure
is allocated as part of re-enabling the slot, but the bandwidth table
pointers are not set up properly here.
This triggers the NULL pointer dereference the next time usb_ep0_reinit()
is called and xhci_configure_endpoint() tries to check and reserve

Fix this by making sure bandwidth table pointers are set up correctly
after a failed address device command, and additionally by avoiding
checking for bandwidth in cases like this where no actual endpoints are
added or removed, i.e. only context for default control endpoint 0 is
evaluated.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau: fix null pointer dereference in nouveau_connector_get_modes
In nouveau_connector_get_modes(), the return value of drm_mode_duplicate()
is assigned to mode, which will lead to a possible NULL pointer
dereference on failure of drm_mode_duplicate(). Add a check to avoid npd.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: nexthop: Initialize all fields in dumped nexthops
struct nexthop_grp contains two reserved fields that are not initialized by
nla_put_nh_group(), and carry garbage. This can be observed e.g. with
strace (edited for clarity):
# ip nexthop add id 1 dev lo
# ip nexthop add id 101 group 1
# strace -e recvmsg ip nexthop get id 101
...
recvmsg(... [{nla_len=12, nla_type=NHA_GROUP},
[{id=1, weight=0, resvd1=0x69, resvd2=0x67}]] ...) = 52
The fields are reserved and therefore not currently used. But as they are, they
leak kernel memory, and the fact they are not just zero complicates repurposing
of the fields for new ends. Initialize the full structure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring: fix possible deadlock in io_register_iowq_max_workers()
The io_register_iowq_max_workers() function calls io_put_sq_data(),
which acquires the sqd->lock without releasing the uring_lock.
Similar to the commit 009ad9f0c6ee ("io_uring: drop ctx->uring_lock
before acquiring sqd->lock"), this can lead to a potential deadlock
situation.
To resolve this issue, the uring_lock is released before calling
io_put_sq_data(), and then it is re-acquired after the function call.
This change ensures that the locks are acquired in the correct
order, preventing the possibility of a deadlock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ax25: Fix reference count leak issues of ax25_dev
The ax25_addr_ax25dev() and ax25_dev_device_down() exist a reference
count leak issue of the object "ax25_dev".
Memory leak issue in ax25_addr_ax25dev():
The reference count of the object "ax25_dev" can be increased multiple
times in ax25_addr_ax25dev(). This will cause a memory leak.
Memory leak issues in ax25_dev_device_down():
The reference count of ax25_dev is set to 1 in ax25_dev_device_up() and
then increase the reference count when ax25_dev is added to ax25_dev_list.
As a result, the reference count of ax25_dev is 2. But when the device is
shutting down. The ax25_dev_device_down() drops the reference count once
or twice depending on if we goto unlock_put or not, which will cause
memory leak.
As for the issue of ax25_addr_ax25dev(), it is impossible for one pointer
to be on a list twice. So add a break in ax25_addr_ax25dev(). As for the
issue of ax25_dev_device_down(), increase the reference count of ax25_dev
once in ax25_dev_device_up() and decrease the reference count of ax25_dev
after it is removed from the ax25_dev_list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_core: cancel all works upon hci_unregister_dev()
syzbot is reporting that calling hci_release_dev() from hci_error_reset()
due to hci_dev_put() from hci_error_reset() can cause deadlock at
destroy_workqueue(), for hci_error_reset() is called from
hdev->req_workqueue which destroy_workqueue() needs to flush.
We need to make sure that hdev->{rx_work,cmd_work,tx_work} which are
queued into hdev->workqueue and hdev->{power_on,error_reset} which are
queued into hdev->req_workqueue are no longer running by the moment
destroy_workqueue(hdev->workqueue);
destroy_workqueue(hdev->req_workqueue);
are called from hci_release_dev().
Call cancel_work_sync() on these work items from hci_unregister_dev()
as soon as hdev->list is removed from hci_dev_list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: fix a deadlock problem when config TC during resetting
When config TC during the reset process, may cause a deadlock, the flow is
as below:
pf reset start
│
▼
......
setup tc │
│ ▼
▼ DOWN: napi_disable()
napi_disable()(skip) │
│ │
▼ ▼
...... ......
│ │
▼ │
napi_enable() │
▼
UINIT: netif_napi_del()
│
▼
......
│
▼
INIT: netif_napi_add()
│
▼
...... global reset start
│ │
▼ ▼
UP: napi_enable()(skip) ......
│ │
▼ ▼
...... napi_disable()
In reset process, the driver will DOWN the port and then UINIT, in this
case, the setup tc process will UP the port before UINIT, so cause the
problem. Adds a DOWN process in UINIT to fix it.

No remote peer input reaches this path, so it requires local access to the host.\nAC:L - The attacker controls both halves of the race: they start the PF reset themselves via `ethtool -r`, and `hclge_reset()` drops rtnl_lock for the entire hardware-reset wait, leaving a long, deterministic window in which the tc/mqprio ioctl can be issued in a tight loop until it lands. `hclge_setup_tc()` has no reset-state guard at all, so no condition outside the attacker\u0027s control is involved.\nPR:L - Both triggers (tc qdisc/mqprio and ethtool reset) require only CAP_NET_ADMIN over the hns3 netdevice, which is a delegatable capability held by unprivileged network-management daemons and by the owner of a user namespace whose network namespace holds the device (a dedicated PF handed to a container). This is not full root in the initial namespace, so Low rather than High.\nUI:N - The attacker issues both the reset request and the TC configuration themselves; no action by any other user or administrator is needed.\nS:U - The corruption and the hang are confined to the kernel of the same host, within the same security authority \u2014 there is no hypervisor, IOMMU, or sandbox boundary crossed.\nC:H - Because the missing `hns3_nic_net_stop()` lets `hns3_reset_notify_uninit_enet()` run against a live port, `devm_kfree(priv-\u003etqp_vector)` and `hns3_uninit_all_ring()` free the NAPI contexts, DIM work items and DMA descriptor buffers while NAPI polling, pending DIM works and hardware DMA are still using them. The resulting use-after-free over freed, reallocatable slab memory can be leveraged to read attacker-chosen kernel data.\nI:H - The same use-after-free gives a write primitive \u2014 the uncancelled `rx_group.dim.work`/`tx_group.dim.work` execute against the freed `tqp_vector`, and the NIC continues DMA-writing into freed ring buffers, so heap-sprayed objects can be corrupted, which is exploitable toward control-flow hijack.\nA:H - The documented outcome is a permanent deadlock: `napi_disable()` spins forever on a NAPI that was re-added but never enabled, and it does so while the reset worker holds rtnl_lock, wedging every subsequent network-configuration operation on the machine plus the NIC itself. Any kernel hang/deadlock is High."

Summary
In the Linux kernel, the following vulnerability has been resolved:
gfs2: Fix NULL pointer dereference in gfs2_log_flush
In gfs2_jindex_free(), set sdp->sd_jdesc to NULL under the log flush
lock to provide exclusion against gfs2_log_flush().
In gfs2_log_flush(), check if sdp->sd_jdesc is non-NULL before
dereferencing it. Otherwise, we could run into a NULL pointer
dereference when outstanding glock work races with an unmount
(glock_work_func -> run_queue -> do_xmote -> inode_go_sync ->
gfs2_log_flush).

No VM, IOMMU, or sandbox boundary is crossed.\nC:H - An inflated `init_cb_size` is passed straight to `qla2x00_init_firmware()`, causing the HBA to DMA-read far past the ~5.2 KB coherent ICB allocation and expose adjacent kernel memory to the device; the page-allocator corruption from the mismatched `dma_free_coherent()` further yields read primitives over reused memory.\nI:H - The bug is a direct 16-bit write into an adjacent kernel struct field, which then drives `memset(ha-\u003einit_cb, 0, ha-\u003einit_cb_size)` out of bounds and frees page frames that were never allocated \u2014 classic heap/page-allocator corruption leveragable into a controlled write and control-flow hijack.\nA:H - Out-of-bounds writes and freeing unowned pages readily produce allocator corruption and kernel panics, and a malformed Init Control Block also leaves the HBA misconfigured, taking down storage connectivity on the affected host."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bcachefs: Fix sb_field_downgrade validation
- bch2_sb_downgrade_validate() wasn't checking for a downgrade entry
extending past the end of the superblock section
- for_each_downgrade_entry() is used in to_text() and needs to work on
malformed input; it also was missing a check for a field extending
past the end of the section

"value": "AV:L - The vulnerable code parses device-tree data during device instantiation and driver probe; there is no path by which network- or bus-peer-supplied data reaches `of_irq_parse_one()`. Triggering it requires local presence on the system (module autoload/device instantiation, or applying a DT overlay).\nAC:L - The out-of-bounds read is a deterministic consequence of the DT shape \u2014 any node whose `reg` is shorter than its interrupt parent\u0027s `#address-cells` hits it on every parse, with no race, timing window, or memory-layout condition to win. A party able to supply DT data arranges it trivially, and on an affected platform it fires unconditionally.\nPR:L - On a platform whose shipped device tree carries the `reg`/`#address-cells` mismatch \u2014 a real, observed configuration in the reporting bug \u2014 an unprivileged local user can drive the affected node through `device_add()`/`platform_get_irq()` by triggering module autoload or device instantiation, with no capability required. Full control over the DT blob would need root or firmware access, but that stronger requirement is not necessary to reach the faulty read.\nUI:N - Interrupt resolution happens automatically during device registration and driver probe; no victim action such as opening a file or mounting a filesystem is involved.\nS:U - The out-of-bounds read and its consequences are confined to kernel memory and kernel IRQ-routing state within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Up to ~60 bytes of adjacent slab memory beyond the `reg` allocation are read into `initial_match_array`, well past the \"few bytes\" threshold and unconstrained as to what neighbouring heap object is disclosed. The values then steer interrupt-map matching, so the resulting IRQ assignment observable in `/proc/interrupts` acts as an oracle on out-of-bounds heap contents.\nI:L - The out-of-bounds bytes are used directly as the match key for the interrupt-map walk, so uninitialized adjacent-heap data determines which interrupt parent and hwirq the device is bound to \u2014 a genuine but bounded corruption of kernel device configuration. There is no write primitive, so arbitrary modification or control-flow hijack is not achievable.\nA:H - With KASAN or arm64 MTE (`KASAN_HW_TAGS`, enabled on production Android) and `kasan.fault=panic`, the slab out-of-bounds read is an immediate kernel panic; for the base unflattened DT blob the read can also run past the final page and oops. Misrouted interrupts from a bogus match additionally leave the affected device non-functional."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau: prime: fix refcount underflow
Calling nouveau_bo_ref() on a nouveau_bo without initializing it (and
hence the backing ttm_bo) leads to a refcount underflow.
Instead of calling nouveau_bo_ref() in the unwind path of
drm_gem_object_init(), clean things up manually.
(cherry picked from commit 1b93f3e89d03cfc576636e195466a0d728ad8de5)

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:
firmware: cs_dsp: Use strnlen() on name fields in V1 wmfw files
Use strnlen() instead of strlen() on the algorithm and coefficient name
string arrays in V1 wmfw files.
In V1 wmfw files the name is a NUL-terminated string in a fixed-size
array. cs_dsp should protect against overrunning the array if the NUL
terminator is missing.

No remote or adjacent-bus peer data reaches this parser.\nAC:L - The attacker authors the entire file, so simply omitting the NUL terminator and keeping every byte to EOF non-zero makes `strlen()` deterministically run off the end of the `vmalloc()`\u0027d firmware buffer \u2014 no race, timing window, or memory-layout luck is involved, and the parse can be re-triggered on demand through the preload control.\nPR:L - The parse is triggered by any unprivileged local user with `/dev/snd` access (`wm_adsp2_preloader_put()` and normal playback/DAPM power-up perform no capability check), and the blob is not always root-exclusive in practice \u2014 firmware-staging/update agents, bind-mounts over `/lib/firmware/updates`, and delegated fallback-loader setups can place it within reach of a low-privileged account; choosing the higher-severity option between L and H.\nUI:N - Once the crafted wmfw is in place it is fetched and parsed automatically at driver probe or first audio stream, and the attacker can force the load from their own process via the DSP preloader; no victim action is required.\nS:U - The over-read and its consequences stay within the kernel\u0027s own security authority (the cs_dsp parser and the codec it drives); no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - `strlen()` on an unterminated 256-byte array performs an unbounded out-of-bounds read that first traverses the un-zeroed tail of the final `vmalloc()` page \u2014 stale kernel page contents \u2014 and those bytes are echoed to the kernel log through the `cs_dsp_dbg(\"Algorithm name: %.*s\")`/`(\"Coefficient name: %.*s\")` prints, so the disclosure is neither bounded to a few bytes nor confined to the driver.\nI:L - The out-of-bounds-derived `name_len` is propagated as `subname_len` into `cs_dsp_create_control()`, where it decides whether an existing control is reused or a new one is added, leaving driver control state inconsistent with the file; this is bounded, attacker-influenced modification with no arbitrary-write primitive, since the V1 path does not copy the name (`fw_ver \u003e= 2` gate).\nA:H - With no NUL byte before EOF the scan walks past the end of the `vmalloc()`\u0027d firmware buffer into the guard page, producing an unhandled page fault/oops (and a KASAN out-of-bounds panic on hardened builds), which an unprivileged user can re-trigger at will through the DSP preload control."

Summary
In the Linux kernel, the following vulnerability has been resolved:
cachefiles: fix slab-use-after-free in cachefiles_withdraw_cookie()
We got the following issue in our fault injection stress test:
==================================================================

[...]
==================================================================
Following is the process that triggers the issue:
p1 | p2
------------------------------------------------------------
fscache_begin_lookup
fscache_begin_volume_access
fscache_cache_is_live(fscache_cache)
cachefiles_daemon_release
cachefiles_put_unbind_pincount
cachefiles_daemon_unbind
cachefiles_withdraw_cache
fscache_withdraw_cache
fscache_set_cache_state(cache, FSCACHE_CACHE_IS_WITHDRAWN);
cachefiles_withdraw_objects(cache)
fscache_wait_for_objects(fscache)
atomic_read(&fscache_cache->object_count) == 0
fscache_perform_lookup
cachefiles_lookup_cookie
cachefiles_alloc_object
refcount_set(&object->ref, 1);
object->volume = volume
fscache_count_object(vcookie->cache);
atomic_inc(&fscache_cache->object_count)
cachefiles_withdraw_volumes
cachefiles_withdraw_volume
fscache_withdraw_volume
__cachefiles_free_volume
kfree(cachefiles_volume)
fscache_cookie_state_machine
cachefiles_withdraw_cookie
cache = object->volume->cache;
// cachefiles_volume UAF !!!
After setting FSCACHE_CACHE_IS_WITHDRAWN, wait for all the cookie lookups
to complete first, and then wait for fscache_cache->object_count == 0 to
avoid the cookie exiting after the volume has been freed and triggering
the above issue. Therefore call fscache_withdraw_volume() before calling
cachefiles_withdraw_objects().
This way, after setting FSCACHE_CACHE_IS_WITHDRAWN, only the following two
cases will occur:
1) fscache_begin_lookup fails in fscache_begin_volume_access().
2) fscache_withdraw_volume() will ensure that fscache_count_object() has
been executed before calling fscache_wait_for_objects().

Summary
In the Linux kernel, the following vulnerability has been resolved:
wireguard: allowedips: avoid unaligned 64-bit memory accesses
On the parisc platform, the kernel issues kernel warnings because
swap_endian() tries to load a 128-bit IPv6 address from an unaligned
memory location:
Kernel: unaligned access to 0x55f4688c in wg_allowedips_insert_v6+0x2c/0x80 [wireguard] (iir 0xf3010df)
Kernel: unaligned access to 0x55f46884 in wg_allowedips_insert_v6+0x38/0x80 [wireguard] (iir 0xf2010dc)
Avoid such unaligned memory accesses by instead using the
get_unaligned_be64() helper macro.
[Jason: replace src[8] in original patch with src+8]

Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: Fix XDP program unloading while removing the driver
The commit 6533e558c650 ("i40e: Fix reset path while removing
the driver") introduced a new PF state "__I40E_IN_REMOVE" to block
modifying the XDP program while the driver is being removed.
Unfortunately, such a change is useful only if the ".ndo_bpf()"
callback was called out of the rmmod context because unloading the
existing XDP program is also a part of driver removing procedure.
In other words, from the rmmod context the driver is expected to
unload the XDP program without reporting any errors. Otherwise,
the kernel warning with callstack is printed out to dmesg.
Example failing scenario:
1. Load the i40e driver.
2. Load the XDP program.
3. Unload the i40e driver (using "rmmod" command).
The example kernel warning log:

Fix this by checking if the XDP program is being loaded or unloaded.
Then, block only loading a new program while "__I40E_IN_REMOVE" is set.
Also, move testing "__I40E_IN_REMOVE" flag to the beginning of XDP_SETUP
callback to avoid unnecessary operations and checks.

Whether the machine contains an ASIC reporting more than six streams is entirely a property of the installed silicon and wholly outside any attacker\u0027s influence.\nPR:N - No capability check, credential test, or access-control gate exists anywhere on the path \u2014 `amdgpu_dm_initialize_drm_device()` runs unconditionally as part of the IP-block hardware init during device probe. On a system with qualifying hardware the out-of-bounds accesses occur automatically at boot before any account exists, so the attacker needs no privileges at all.\nUI:N - The amdgpu display manager initializes automatically when the PCI device is probed at boot; no victim must open a file, mount anything, or take any other action.\nS:U - The out-of-bounds read and write both stay inside kernel memory (`struct dc_caps` and `struct amdgpu_device`) and are handled entirely by the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Reading `dc-\u003ecaps.planes[i]` past index 5 pulls adjacent `struct dc_caps` bytes (`color`, `dmub_caps`, and following fields) and misinterprets them as a `struct dc_plane_cap`, from which `amdgpu_dm_plane_init()` derives the advertised pixel formats, DRM format modifiers, and upscale/downscale limits that any local user holding a DRM fd can read back via `DRM_IOCTL_MODE_GETPLANE` and the `IN_FORMATS` blob. The accompanying heap-pointer overwrite of `struct amdgpu_device` is memory corruption that can be leveraged for further disclosure.\nI:H - `initialize_plane()` writes a freshly kzalloc\u0027d `struct drm_plane *` past the end of `mode_info-\u003eplanes[6]`, corrupting the adjacent `afmt[9]` pointer array and DRM property pointers inside `struct amdgpu_device`; the subsequent `amdgpu_dm_crtc_init(dm, mode_info-\u003eplanes[i], i)` reads those slots back out of bounds and passes type-confused pointers to `drm_crtc_init_with_planes()`. An out-of-bounds pointer write combined with type confusion is a control-flow-relevant corruption primitive.\nA:H - The pre-fix `ASSERT()` expands to `WARN_ON_ONCE()`, which panics outright on the many builds running `panic_on_warn=1`, and execution then continues into the out-of-bounds accesses that corrupt `struct amdgpu_device` and dereference type-confused pointers during display init, crashing the kernel or leaving the machine unbootable/headless."

Summary
In the Linux kernel, the following vulnerability has been resolved:
VMCI: Fix use-after-free when removing resource in vmci_resource_remove()
When removing a resource from vmci_resource_table in
vmci_resource_remove(), the search is performed using the resource
handle by comparing context and resource fields.
It is possible though to create two resources with different types
but same handle (same context and resource fields).
When trying to remove one of the resources, vmci_resource_remove()
may not remove the intended one, but the object will still be freed
as in the case of the datagram type in vmci_datagram_destroy_handle().
vmci_resource_table will still hold a pointer to this freed resource
leading to a use-after-free vulnerability.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/radeon: check bo_va->bo is non-NULL before using it
The call to radeon_vm_clear_freed might clear bo_va->bo, so
we have to check it before dereferencing it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i2c: pnx: Fix potential deadlock warning from del_timer_sync() call in isr
When del_timer_sync() is called in an interrupt context it throws a warning
because of potential deadlock. The timer is used only to exit from
wait_for_completion() after a timeout so replacing the call with
wait_for_completion_timeout() allows to remove the problematic timer and
its related functions altogether.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/pseries: Fix scv instruction crash with kexec
kexec on pseries disables AIL (reloc_on_exc), required for scv
instruction support, before other CPUs have been shut down. This means
they can execute scv instructions after AIL is disabled, which causes an
interrupt at an unexpected entry location that crashes the kernel.
Change the kexec sequence to disable AIL after other CPUs have been
brought down.
As a refresher, the real-mode scv interrupt vector is 0x17000, and the
fixed-location head code probably couldn't easily deal with implementing
such high addresses so it was just decided not to support that interrupt
at all.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: mana: Fix possible double free in error handling path
When auxiliary_device_add() returns error and then calls
auxiliary_device_uninit(), callback function adev_release
calls kfree(madev). We shouldn't call kfree(madev) again
in the error handling path. Set 'madev' to NULL.

No remotely received network data reaches this code, and the failing `auxiliary_device_add()` name/id are kernel-generated, so even a malicious device cannot steer it.\nAC:L - The only precondition is an allocation failure inside `dev_set_name()`/`device_add()`, which a local attacker can induce by driving the system into memory pressure while repeatedly cycling the probe path until the window is hit. Nothing in the path depends on state outside the attacker\u0027s influence, and the attempt can be retried indefinitely.\nPR:L - The triggering condition \u2014 memory exhaustion making `GFP_KERNEL` allocations fail \u2014 is fully inducible by an ordinary unprivileged local user, and MANA probe events also occur unprivileged in Azure guests (boot, host-initiated VF hot-add/revoke during servicing and live migration). This matches the scoring of CVE-2026-43056, the sibling defect in the identical error path of this same function.\nUI:N - The entire sequence runs inside kernel probe/resume context with no human action required \u2014 no mount, file open, or click. Probe is driven by the PCI/driver core and by host-initiated hotplug.\nS:U - The double free and use-after-free corrupt kernel slab objects within the same security authority as the vulnerable driver. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - `mana_adev_idx_free(adev-\u003eid)` reads `adev-\u003eid` out of memory already released by `adev_release()`, and the subsequent double free creates a SLUB freelist cycle that hands the same `kmalloc-1k`/`kmalloc-2k` object to two independent allocations. Because that is a general-purpose cache shared with attacker-sprayable objects, the resulting type confusion is leverageable into a kernel memory disclosure primitive.\nI:H - A double free giving two owners of one slab object is the classic dup-alloc primitive: the attacker reclaims the chunk with a groomed structure while the driver still writes through the stale `struct device`/`auxiliary_device` fields, yielding arbitrary write and function-pointer hijack. The stale `adev-\u003eid` is additionally fed into `ida_free()`, corrupting global IDA allocator state.\nA:H - On kernels with `CONFIG_SLAB_FREELIST_HARDENED`, the immediate re-free trips `set_freepointer()`\u0027s `BUG_ON(object == fp)` for a hard kernel panic; without it, the poisoned freelist causes an oops or arbitrary corruption shortly after. Either outcome takes down the machine and can be re-triggered on every probe cycle."

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix missing cleanup on rollforward recovery error
In an error injection test of a routine for mount-time recovery, KASAN
found a use-after-free bug.
It turned out that if data recovery was performed using partial logs
created by dsync writes, but an error occurred before starting the log
writer to create a recovered checkpoint, the inodes whose data had been
recovered were left in the ns_dirty_files list of the nilfs object and
were not freed.
Fix this issue by cleaning up inodes that have read the recovery data if
the recovery routine fails midway before the log writer starts.

Summary
In the Linux kernel, the following vulnerability has been resolved:
staging: iio: frequency: ad9834: Validate frequency parameter value
In ad9834_write_frequency() clk_get_rate() can return 0. In such case
ad9834_calc_freqreg() call will lead to division by zero. Checking
'if (fout > (clk_freq / 2))' doesn't protect in case of 'fout' is 0.
ad9834_write_frequency() is called from ad9834_write(), where fout is
taken from text buffer, which can contain any value.
Modify parameters checking.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ata: libata-core: Fix double free on error
If e.g. the ata_port_alloc() call in ata_host_alloc() fails, we will jump
to the err_out label, which will call devres_release_group().
devres_release_group() will trigger a call to ata_host_release().
ata_host_release() calls kfree(host), so executing the kfree(host) in
ata_host_alloc() will lead to a double free:

No remote peer or network protocol data ever reaches this code, so local access to the system is required.\nAC:L - The double free is a deterministic code-path defect \u2014 once `ata_port_alloc()` returns NULL, `devres_release_group()`\u0027s `ata_devres_release()` \u2192 `ata_host_release()` \u2192 `kfree(host)` and the fall-through `kfree(host)` always both execute, with no race or memory-layout requirement. The enabling allocation failure targets a large (~13 KB, order-2) `GFP_KERNEL` slab allocation, which an attacker can influence through sustained memory exhaustion and retry indefinitely across repeated probe/hotplug/bind attempts.\nPR:L - The attacker\u0027s own contribution \u2014 driving the system into the memory-pressure state that makes the probe-time `kzalloc()` fail \u2014 requires only ordinary unprivileged local execution, while the probe itself is initiated by routine system activity (boot, udev worker, device hotplug) rather than by any privilege the attacker must hold.\nUI:N - ATA host controller probes are performed automatically by the kernel and udev during enumeration, hotplug, and module load; no administrator or victim action is needed for the vulnerable path to execute.\nS:U - The corruption is confined to the kernel slab allocator of the same host, producing a conventional local kernel compromise or panic. No VM, hypervisor, or IOMMU boundary is crossed.\nC:H - A double free of a `kmalloc`\u0027d object poisons the SLUB freelist so that two independent allocations return the same memory, overlapping `struct ata_host` with an arbitrary other kernel object and giving the attacker a read view into structures they should not see. This is a memory-corruption primitive that can be leveraged for kernel information disclosure.\nI:H - The same freelist-aliasing/type-confusion condition yields a write primitive: one object\u0027s writes land inside another live kernel allocation, enabling corruption of function pointers or credential structures and control-flow hijacking. Double frees are a well-established route to kernel privilege escalation.\nA:H - On kernels with `CONFIG_SLAB_FREELIST_HARDENED`/SLUB debugging \u2014 the distro default \u2014 the second `kfree()` trips `kernel BUG at mm/slub.c:553`, producing the `Oops: invalid opcode` and kernel panic reproduced in the commit message. Even without detection, the aliased slab objects readily corrupt unrelated kernel state and crash the system."

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfs: Fix netfs_page_mkwrite() to check folio->mapping is valid
Fix netfs_page_mkwrite() to check that folio->mapping is valid once it has
taken the folio lock (as filemap_page_mkwrite() does). Without this,
generic/247 occasionally oopses with something like the following:
BUG: kernel NULL pointer dereference, address: 0000000000000000
#PF: supervisor read access in kernel mode
#PF: error_code(0x0000) - not-present page
RIP: 0010:trace_event_raw_event_netfs_folio+0x61/0xc0
...

This is due to the invalidate_inode_pages2_range() issued at the end of the
DIO write interfering with the mmap'd writes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: avoid using null object of framebuffer
Instead of using state->fb->obj[0] directly, get object from framebuffer
by calling drm_gem_fb_get_obj() and return error code when object is
null to avoid using null object of framebuffer.

There is no network or adjacent-network exposure.\nAC:L - On affected hardware the bad index is fully deterministic \u2014 `info-\u003esrc_id` is a hardcoded 0 in the dce60 VUPDATE table entries, so `dc_interrupt_to_irq_source()` always returns `DC_IRQ_SOURCE_INVALID` and `pipe_offset` always wraps to 178; there is no race, no timing window, and no memory-layout precondition needed to reach the out-of-bounds access, which the attacker triggers at will by toggling vblank.\nPR:L - `drm_wait_vblank_ioctl` is registered with flags `0` (no DRM_AUTH, DRM_MASTER, or DRM_ROOT_ONLY), so any unprivileged local process holding an open handle to the card node \u2014 which the seat user gets automatically via logind ACLs, or any member of the `video` group \u2014 can drive the vblank refcount into this path. No root or capability is required.\nUI:N - The attacking process issues the vblank ioctl itself and the vblank-disable path invokes `amdgpu_dm_crtc_set_vupdate_irq()` unconditionally; no action by another user or victim is needed.\nS:U - The out-of-bounds access and its consequences are confined to the kernel\u0027s own memory and the amdgpu driver\u0027s security authority; no VM, hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The read is roughly 400\u2013700 KB past the six-element `pipe_ctx[]` array \u2014 far from a strictly bounded few-byte overread \u2014 and pulls an arbitrary quadword out of neighbouring kernel allocations; that value is used as the `tg` pointer and its contents feed `arm_vert_intr()` register programming, so it is an unbounded kernel-memory disclosure primitive rather than a small bounded leak.\nI:H - On the enable path the out-of-bounds value is treated as a `struct timing_generator *` and dereferenced twice with an indirect call \u2014 `tg-\u003efuncs-\u003earm_vert_intr(tg, 2)` \u2014 giving a control-flow hijack primitive if the memory ~178 pipe_ctx entries past the array can be groomed, and the resulting hardware register writes are driven from that attacker-uninfluenced object.\nA:H - `dc_state` is `kvzalloc`\u0027d and therefore vmalloc-backed with guard pages at this size, so indexing hundreds of kilobytes past `res_ctx.pipe_ctx[]` reads unmapped memory and oopses, and any wild `tg` value that survives the load is then dereferenced and called, panicking the kernel; the attacker can repeat the trigger arbitrarily."

Summary
In the Linux kernel, the following vulnerability has been resolved:
libceph: fix race between delayed_work() and ceph_monc_stop()
The way the delayed work is handled in ceph_monc_stop() is prone to
races with mon_fault() and possibly also finish_hunting(). Both of
these can requeue the delayed work which wouldn't be canceled by any of
the following code in case that happens after cancel_delayed_work_sync()
runs -- __close_session() doesn't mess with the delayed work in order
to avoid interfering with the hunting interval logic. This part was
missed in commit b5d91704f53e ("libceph: behave in mon_fault() if
cur_mon < 0") and use-after-free can still ensue on monc and objects
that hang off of it, with monc->auth and monc->monmap being
particularly susceptible to quickly being reused.
To fix this:
- clear monc->cur_mon and monc->hunting as part of closing the session
in ceph_monc_stop()
- bail from delayed_work() if monc->cur_mon is cleared, similar to how
it's done in mon_fault() and finish_hunting() (based on monc->hunting)
- call cancel_delayed_work_sync() after the session is closed

No local access to the target is needed for the attacker\u0027s contribution.\nAC:L - The attacker controls both sides of the race: it drives connection faults at an arbitrary rate and induces the `ceph_monc_stop()` teardown by refusing/resetting the session, and the window is amplified because `mon_fault()` holds `monc-\u003emutex` while `ceph_monc_stop()` blocks on it after the cancel has already run. The attempt is free and infinitely repeatable across mount/unmount cycles.\nPR:N - The attacker is an unauthenticated remote peer \u2014 `con_fault()` fires on socket errors before any cephx authentication succeeds, and the monitor is the entity the client authenticates *to*, so no credentials on the victim host are required.\nUI:N - No victim action is needed beyond normal, automated cluster operation \u2014 ceph-csi/Kubernetes, autofs and systemd mount units perform cephfs/rbd mount, unmount and retry cycles continuously without human involvement, and each failed or torn-down session is an exploitation attempt.\nS:U - The use-after-free corrupts kernel heap memory and executes within the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - Use-after-free on `ceph_client`/`ceph_mon_client`, `ceph_auth_client` and `ceph_monmap`, with `pick_new_mon()` indexing `monc-\u003emonmap-\u003emon_inst[monc-\u003ecur_mon]` using a base pointer and index both read from freed, attacker-groomable memory \u2014 an out-of-bounds read primitive usable for kernel memory disclosure.\nI:H - `ceph_auth_is_authenticated()` performs `ac-\u003eops-\u003eis_authenticated(ac)`, an indirect call through a function pointer read from a freed slab object the remote monitor can reclaim during the multi-second delay, giving control-flow hijack; `mutex_lock()` and `mod_delayed_work()` additionally write timer/work state into the freed-and-reused allocation.\nA:H - The delayed work executing on freed memory reliably oopses, and `BUG_ON(monc-\u003emonmap-\u003enum_mon \u003c 1)` in `pick_new_mon()` panics the kernel outright when the freed monmap is reused."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Check pat.ops before dumping PAT settings
We may leave pat.ops unset when running on brand new platform or
when running as a VF. While the former is unlikely, the latter
is valid (future) use case and will cause NPD when someone will
try to dump PAT settings by debugfs.
It's better to check pointer to pat.ops instead of specific .dump
hook, as we have this hook always defined for every .ops variant.

In the Linux kernel, the following vulnerability has been resolved:
media: pci: cx23885: check cx23885_vdev_init() return
cx23885_vdev_init() can return a NULL pointer, but that pointer
is used in the next line without a check.
Add a NULL pointer check and go to the error unwind if it is NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bonding: Fix out-of-bounds read in bond_option_arp_ip_targets_set()
In function bond_option_arp_ip_targets_set(), if newval->string is an
empty string, newval->string+1 will point to the byte after the
string, causing an out-of-bound read.
BUG: KASAN: slab-out-of-bounds in strlen+0x7d/0xa0 lib/string.c:418
Read of size 1 at addr ffff8881119c4781 by task syz-executor665/8107

This requires local access, not network traffic.\nAC:L - A single deterministic write of one NUL byte produces the empty string and triggers the out-of-bounds strlen() every time \u2014 no race, no timing window, and no dependence on memory layout to reach the OOB access.\nPR:L - Verified empirically as uid 1000: inside `unshare -Urnm` the bond netdev\u0027s sysfs group is owned by the user namespace\u0027s root (net_class.get_ownership \u2192 net_ns_get_ownership), which maps to the attacker\u0027s real uid, so an unprivileged user can create the bond and write the attribute. No real root or init-namespace capability is needed.\nUI:N - The attacker performs the entire sequence (create netns/userns, create bond device, write the sysfs file) unaided; no victim action is involved.\nS:U - The out-of-bounds read stays within the kernel\u0027s own memory and security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - strlen() walks adjacent slab memory with no upper bound until it happens to find a NUL byte, and parsed heap bytes forming a dotted quad are stored in bond-\u003eparams.arp_targets where any user can read them back via the world-readable arp_ip_target attribute or netlink; the pre-fix error path also leaked uninitialized kernel stack through %pI4.\nI:N - The defect is a read-only out-of-bounds access with no write primitive; the only state changed is the bond\u0027s own ARP target list, which the same actor could already set legitimately through the identical interface.\nA:H - The unbounded read can run past the end of the slab page into unmapped memory (e.g. with DEBUG_PAGEALLOC/page poisoning) causing an oops, and on KASAN kernels it produces the reported slab-out-of-bounds report/panic, repeatable at will by an unprivileged user."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix DIO failure due to insufficient transaction credits
The code in ocfs2_dio_end_io_write() estimates number of necessary
transaction credits using ocfs2_calc_extend_credits(). This however does
not take into account that the IO could be arbitrarily large and can
contain arbitrary number of extents.
Extent tree manipulations do often extend the current transaction but not
in all of the cases. For example if we have only single block extents in
the tree, ocfs2_mark_extent_written() will end up calling
ocfs2_replace_extent_rec() all the time and we will never extend the
current transaction and eventually exhaust all the transaction credits if
the IO contains many single block extents. Once that happens a
WARN_ON(jbd2_handle_buffer_credits(handle) <= 0) is triggered in
jbd2_journal_dirty_metadata() and subsequently OCFS2 aborts in response to
this error. This was actually triggered by one of our customers on a
heavily fragmented OCFS2 filesystem.
To fix the issue make sure the transaction always has enough credits for
one extent insert before each call of ocfs2_mark_extent_written().

That failure propagates back to pci_msi_setup_msi_irqs() in
msi_capability_init() which accesses the descriptor for unmasking in the
error exit path.
Cure it by copying the descriptor and using the copy for the error exit path
unmask operation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: ASSERT when failing to find index by plane/stream id
[WHY]
find_disp_cfg_idx_by_plane_id and find_disp_cfg_idx_by_stream_id returns
an array index and they return -1 when not found; however, -1 is not a
valid index number.
[HOW]
When this happens, call ASSERT(), and return a positive number (which is
fewer than callers' array size) instead.
This fixes 4 OVERRUN and 2 NEGATIVE_RETURNS issues reported by Coverity.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Fix ufshcd_clear_cmd racing issue
When ufshcd_clear_cmd is racing with the completion ISR, the completed tag
of the request's mq_hctx pointer will be set to NULL by the ISR. And
ufshcd_clear_cmd's call to ufshcd_mcq_req_to_hwq will get NULL pointer KE.
Return success when the request is completed by ISR because sq does not
need cleanup.
The racing flow is:
Thread A
ufshcd_err_handler step 1
ufshcd_try_to_abort_task
ufshcd_cmd_inflight(true) step 3
ufshcd_clear_cmd
...
ufshcd_mcq_req_to_hwq
blk_mq_unique_tag
rq->mq_hctx->queue_num step 5
Thread B
ufs_mtk_mcq_intr(cq complete ISR) step 2
scsi_done
...
__blk_mq_free_request
rq->mq_hctx = NULL; step 4
Below is KE back trace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: add sanity checks to rx zerocopy
TCP rx zerocopy intent is to map pages initially allocated
from NIC drivers, not pages owned by a fs.
This patch adds to can_map_frag() these additional checks:
- Page must not be a compound one.
- page->mapping must be NULL.
This fixes the panic reported by ZhangPeng.
syzbot was able to loopback packets built with sendfile(),
mapping pages owned by an ext4 file to TCP rx zerocopy.

A purely remote peer cannot supply page-cache or compound pages into the receive frags, since those come from the local NIC/page_pool allocator.\nAC:L - The syzbot reproducer is fully deterministic with no race window and no dependence on memory layout: sendfile() guarantees PAGE_SIZE frags at offset 0 pointing at ext4 page-cache pages, and loopback delivers them unchanged to the same socket\u0027s receive queue. Follow-on inode eviction is likewise triggered on demand by the attacker via O_TRUNC/unlink+close.\nPR:L - Every step is available to an ordinary unprivileged user \u2014 tcp_mmap() performs no capability check, TCP_ZEROCOPY_RECEIVE is unconditionally compiled in under CONFIG_MMU, and sendfile() on a file the user owns needs no privilege. No CAP_NET_ADMIN or namespace trickery is required at all.\nUI:N - A single unprivileged process performs the entire sequence against itself via a loopback self-connect; no victim process must be running, and no administrator or user action is needed.\nS:U - The corruption is confined to the kernel\u0027s own page-cache/rmap accounting and the attacking process\u0027s address space, managed by the same security authority. There is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - Because the page is mapped outside the inode\u0027s i_mmap tree, filemap_unaccount_folio()\u0027s recovery path resets mapcount and subtracts the PTE\u0027s reference, letting the page be freed and reallocated while the attacker retains a valid read-only PTE to it \u2014 an arbitrary-read window into whatever kernel data (slab objects, page tables, other processes\u0027 pages) subsequently occupies that physical page.\nI:H - The dropped reference plus the later munmap-time page_remove_rmap()/put_page() drives _mapcount and the page refcount negative, producing a double-free of a buddy-allocator page that can be handed out twice and used as a write primitive into kernel-owned memory. The mismatched rmap/_nr_pages_mapped accounting for compound folios corrupts kernel state directly.\nA:H - This is exactly the reported crash \u2014 truncating the file makes filemap_unaccount_folio() hit VM_BUG_ON_FOLIO(folio_mapped(folio)) and panic the kernel; on non-DEBUG_VM builds it produces \"BUG: Bad page cache\"/bad-page-state taints and freelist corruption that destabilizes the whole system."

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: scrub: handle RST lookup error correctly
[BUG]
When running btrfs/060 with forced RST feature, it would crash the
following ASSERT() inside scrub_read_endio():
ASSERT(sector_nr < stripe->nr_sectors);
Before that, we would have tree dump from
btrfs_get_raid_extent_offset(), as we failed to find the RST entry for
the range.
[CAUSE]
Inside scrub_submit_extent_sector_read() every time we allocated a new
bbio we immediately called btrfs_map_block() to make sure there was some
RST range covering the scrub target.
But if btrfs_map_block() fails, we immediately call endio for the bbio,
while the bbio is newly allocated, it's completely empty.
Then inside scrub_read_endio(), we go through the bvecs to find
the sector number (as bi_sector is no longer reliable if the bio is
submitted to lower layers).
And since the bio is empty, such bvecs iteration would not find any
sector matching the sector, and return sector_nr == stripe->nr_sectors,
triggering the ASSERT().
[FIX]
Instead of calling btrfs_map_block() after allocating a new bbio, call
btrfs_map_block() first.
Since our only objective of calling btrfs_map_block() is only to update
stripe_len, there is really no need to do that after btrfs_alloc_bio().
This new timing would avoid the problem of handling empty bbio
completely, and in fact fixes a possible race window for the old code,
where if the submission thread is the only owner of the pending_io, the
scrub would never finish (since we didn't decrease the pending_io
counter).
Although the root cause of RST lookup failure still needs to be
addressed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix array-index-out-of-bounds in dml2/FCLKChangeSupport
[Why]
Potential out of bounds access in dml2_calculate_rq_and_dlg_params()
because the value of out_lowest_state_idx used as an index for FCLKChangeSupport
array can be greater than 1.
[How]
Currently dml2 core specifies identical values for all FCLKChangeSupport
elements. Always use index 0 in the condition to avoid out of bounds access.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ppp: reject claimed-as-LCP but actually malformed packets
Since 'ppp_async_encode()' assumes valid LCP packets (with code
from 1 to 7 inclusive), add 'ppp_check_packet()' to ensure that
LCP packet has an actual body beyond PPP_LCP header bytes, and
reject claimed-as-LCP but actually malformed data otherwise.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sctp: Fix null-ptr-deref in reuseport_add_sock().
syzbot reported a null-ptr-deref while accessing sk2->sk_reuseport_cb in
reuseport_add_sock(). [0]
The repro first creates a listener with SO_REUSEPORT. Then, it creates
another listener on the same port and concurrently closes the first
listener.
The second listen() calls reuseport_add_sock() with the first listener as
sk2, where sk2->sk_reuseport_cb is not expected to be cleared concurrently,
but the close() does clear it by reuseport_detach_sock().
The problem is SCTP does not properly synchronise reuseport_alloc(),
reuseport_add_sock(), and reuseport_detach_sock().
The caller of reuseport_alloc() and reuseport_{add,detach}_sock() must
provide synchronisation for sockets that are classified into the same
reuseport group.
Otherwise, such sockets form multiple identical reuseport groups, and
all groups except one would be silently dead.
1. Two sockets call listen() concurrently
2. No socket in the same group found in sctp_ep_hashtable[]
3. Two sockets call reuseport_alloc() and form two reuseport groups
4. Only one group hit first in __sctp_rcv_lookup_endpoint() receives
incoming packets
Also, the reported null-ptr-deref could occur.
TCP/UDP guarantees that would not happen by holding the hash bucket lock.
Let's apply the locking strategy to __sctp_hash_endpoint() and
__sctp_unhash_endpoint().

Only one group hit first in __sctp_rcv_lookup_endpoint() receives\n incoming packets\n\nAlso, the reported null-ptr-deref could occur.\n\nTCP/UDP guarantees that would not happen by holding the hash bucket lock.\n\nLet\u0027s apply the locking strategy to __sctp_hash_endpoint() and\n__sctp_unhash_endpoint().\n\n[0]:\nOops: general protection fault, probably for non-canonical address 0xdffffc0000000002: 0000 [#1] PREEMPT SMP KASAN PTI\nKASAN: null-ptr-deref in range [0x0000000000000010-0x0000000000000017]\nCPU: 1 UID: 0 PID: 10230 Comm: syz-executor119 Not tainted 6.10.0-syzkaller-12585-g301927d2d2eb #0\nHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 06/27/2024\nRIP: 0010:reuseport_add_sock+0x27e/0x5e0 net/core/sock_reuseport.c:350\nCode: 00 0f b7 5d 00 bf 01 00 00 00 89 de e8 1b a4 ff f7 83 fb 01 0f 85 a3 01 00 00 e8 6d a0 ff f7 49 8d 7e 12 48 89 f8 48 c1 e8 03 \u003c42\u003e 0f b6 04 28 84 c0 0f 85 4b 02 00 00 41 0f b7 5e 12 49 8d 7e 14\nRSP: 0018:ffffc9000b947c98 EFLAGS: 00010202\nRAX: 0000000000000002 RBX: ffff8880252ddf98 RCX: ffff888079478000\nRDX: 0000000000000000 RSI: 0000000000000001 RDI: 0000000000000012\nRBP: 0000000000000001 R08: ffffffff8993e18d R09: 1ffffffff1fef385\nR10: dffffc0000000000 R11: fffffbfff1fef386 R12: ffff8880252ddac0\nR13: dffffc0000000000 R14: 0000000000000000 R15: 0000000000000000\nFS: 00007f24e45b96c0(0000) GS:ffff8880b9300000(0000) knlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 00007ffcced5f7b8 CR3: 00000000241be000 CR4: 00000000003506f0\nDR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\nCall Trace:\n \u003cTASK\u003e\n __sctp_hash_endpoint net/sctp/input.c:762 [inline]\n sctp_hash_endpoint+0x52a/0x600 net/sctp/input.c:790\n sctp_listen_start net/sctp/socket.c:8570 [inline]\n sctp_inet_listen+0x767/0xa20 net/sctp/socket.c:8625\n __sys_listen_socket net/socket.c:1883 [inline]\n __sys_listen+0x1b7/0x230 net/socket.c:1894\n __do_sys_listen net/socket.c:1902 [inline]\n __se_sys_listen net/socket.c:1900 [inline]\n __x64_sys_listen+0x5a/0x70 net/socket.c:1900\n do_syscall_x64 arch/x86/entry/common.c:52 [inline]\n do_syscall_64+0xf3/0x230 arch/x86/entry/common.c:83\n entry_SYSCALL_64_after_hwframe+0x77/0x7f\nRIP: 0033:0x7f24e46039b9\nCode: 28 00 00 00 75 05 48 83 c4 28 c3 e8 91 1a 00 00 90 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 \u003c48\u003e 3d 01 f0 ff ff 73 01 c3 48 c7 c1 b0 ff ff ff f7 d8 64 89 01 48\nRSP: 002b:00007f24e45b9228 EFLAGS: 00000246 ORIG_RAX: 0000000000000032\nRAX: ffffffffffffffda RBX: 00007f24e468e428 RCX: 00007f24e46039b9\nRDX: 00007f24e46039b9 RSI: 0000000000000003 RDI: 0000000000000004\nRBP: 00007f24e468e420 R08: 00007f24e45b96c0 R09: 00007f24e45b96c0\nR10: 00007f24e45b96c0 R11: 0000000000000246 R12: 00007f24e468e42c\nR13:\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
ima: Fix use-after-free on a dentry's dname.name
->d_name.name can change on rename and the earlier value can be freed;
there are conditions sufficient to stabilize it (->d_lock on dentry,
->d_lock on its parent, ->i_rwsem exclusive on the parent's inode,
rename_lock), but none of those are met at any of the sites. Take a stable
snapshot of the name instead.

CONFIG_IMA with a measurement policy is standard on distro, attestation and secure-boot systems, and the sequence can be looped indefinitely.\nPR:L - Any unprivileged local user can trigger it by exec\u0027ing or opening a file it owns (builtin `tcb` policy measures `BPRM_CHECK`/`MMAP_CHECK` for all uids, and tmpfs is only excluded for `FILE_CHECK`) while renaming that file in a directory it controls such as /tmp or $HOME. No capability, root, or user-namespace trick is required.\nUI:N - Both halves of the race are performed by the attacker\u0027s own two threads; no victim ever has to open, mount, or execute anything.\nS:U - The stale dereference reads kernel heap memory within the same kernel security authority, with no VM, IOMMU, or sandbox boundary crossed.\nC:H - The freed `external_name` is a plain `GFP_KERNEL_ACCOUNT` kmalloc object that returns to the kmalloc-cg slab and can be reclaimed by attacker-sprayed or sensitive kernel objects, and the `strlen()` over it is unbounded so the read runs past the original allocation into adjacent slab data. Those bytes are copied verbatim into the IMA measurement log exposed via securityfs and sent to remote attestation verifiers, and into audit records \u2014 bulk kernel heap disclosure.\nI:H - Attacker-chosen bytes from the reclaimed object land unescaped in the IMA measurement log (`ima_write_template_field_data()` only rewrites spaces, so injected newlines forge whole entries in the newline-delimited `ascii_runtime_measurements` stream) and are hashed into the TPM PCR, corrupting exactly the attestation and audit evidence IMA exists to produce; per use-after-free scoring, reclaim control over the freed object also supports heap-grooming toward stronger primitives.\nA:H - The unbounded `strlen()`/`memcpy()` over a freed slab object whose page may already have been released can fault on unmapped memory and oops the kernel, and the garbage length also feeds `kzalloc()` and audit-buffer sizing; on KASAN/hardened kernels the use-after-free faults immediately, and the whole sequence is repeatable at will by any local user."

Summary
In the Linux kernel, the following vulnerability has been resolved:
eeprom: at24: fix memory corruption race condition
If the eeprom is not accessible, an nvmem device will be registered, the
read will fail, and the device will be torn down. If another driver
accesses the nvmem device after the teardown, it will reference
invalid memory.
Move the failure point before registering the nvmem device.

Summary
In the Linux kernel, the following vulnerability has been resolved:
smack: tcp: ipv4, fix incorrect labeling
Currently, Smack mirrors the label of incoming tcp/ipv4 connections:
when a label 'foo' connects to a label 'bar' with tcp/ipv4,
'foo' always gets 'foo' in returned ipv4 packets. So,
1) returned packets are incorrectly labeled ('foo' instead of 'bar')
2) 'bar' can write to 'foo' without being authorized to write.
Here is a scenario how to see this:
* Take two machines, let's call them C and S,
with active Smack in the default state
(no settings, no rules, no labeled hosts, only builtin labels)
* At S, add Smack rule 'foo bar w'
(labels 'foo' and 'bar' are instantiated at S at this moment)
* At S, at label 'bar', launch a program
that listens for incoming tcp/ipv4 connections
* From C, at label 'foo', connect to the listener at S.
(label 'foo' is instantiated at C at this moment)
Connection succeedes and works.
* Send some data in both directions.
* Collect network traffic of this connection.
All packets in both directions are labeled with the CIPSO
of the label 'foo'. Hence, label 'bar' writes to 'foo' without
being authorized, and even without ever being known at C.
If anybody cares: exactly the same happens with DCCP.
This behavior 1st manifested in release 2.6.29.4 (see Fixes below)
and it looks unintentional. At least, no explanation was provided.
I changed returned packes label into the 'bar',
to bring it into line with the Smack documentation claims.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nsmack: tcp: ipv4, fix incorrect labeling\n\nCurrently, Smack mirrors the label of incoming tcp/ipv4 connections:\nwhen a label \u0027foo\u0027 connects to a label \u0027bar\u0027 with tcp/ipv4,\n\u0027foo\u0027 always gets \u0027foo\u0027 in returned ipv4 packets. So,\n1) returned packets are incorrectly labeled (\u0027foo\u0027 instead of \u0027bar\u0027)\n2) \u0027bar\u0027 can write to \u0027foo\u0027 without being authorized to write.\n\nHere is a scenario how to see this:\n\n* Take two machines, let\u0027s call them C and S,\n with active Smack in the default state\n (no settings, no rules, no labeled hosts, only builtin labels)\n\n* At S, add Smack rule \u0027foo bar w\u0027\n (labels \u0027foo\u0027 and \u0027bar\u0027 are instantiated at S at this moment)\n\n* At S, at label \u0027bar\u0027, launch a program\n that listens for incoming tcp/ipv4 connections\n\n* From C, at label \u0027foo\u0027, connect to the listener at S.\n (label \u0027foo\u0027 is instantiated at C at this moment)\n Connection succeedes and works.\n\n* Send some data in both directions.\n* Collect network traffic of this connection.\n\nAll packets in both directions are labeled with the CIPSO\nof the label \u0027foo\u0027. Hence, label \u0027bar\u0027 writes to \u0027foo\u0027 without\nbeing authorized, and even without ever being known at C.\n\nIf anybody cares: exactly the same happens with DCCP.\n\nThis behavior 1st manifested in release 2.6.29.4 (see Fixes below)\nand it looks unintentional. At least, no explanation was provided.\n\nI changed returned packes label into the \u0027bar\u0027,\nto bring it into line with the Smack documentation claims."

"value": "AV:N - The flaw is in the `inet_conn_request` LSM hook reached from `tcp_v4_route_req()`/`tcp_conn_request()` on receipt of a TCP/IPv4 SYN, plus the syncookie and DCCP paths, so a remote peer triggers it by connecting over routable IPv4. The attacker-supplied CIPSO tag in the incoming packet is what selects the wrong label, making the attack entirely remote and packet-driven.\nAC:L - The mislabeling is deterministic \u2014 no race, no memory-layout dependence, no timing window; every accepted TCP/IPv4 connection from a host absent from the netlabel host list (the default Smack state) is mislabeled. CIPSO labeling is enabled by default at smackfs init and the built-in labels are pre-populated, so no unusual tuning is needed beyond Smack being the active LSM.\nPR:N - The hook runs during SYN processing, before the three-way handshake completes and long before any application-level authentication, so the attacker holds no credentials on the target. The attacker further chooses the CIPSO label presented (e.g. the built-in `@`/web label, which `smk_access()` grants against any object), so no policy-granted standing is required either.\nUI:N - Exploitation needs only a listening socket on the target; no administrator or user on the victim system must open, mount, or click anything. The connection and all subsequent mislabeled traffic are driven entirely by the attacker.\nS:U - The mislabeling and the resulting authorization failure both occur within the kernel\u0027s Smack MAC enforcement, the same security authority that owns the vulnerable code. No virtualization, IOMMU, or hypervisor boundary is crossed.\nC:H - All data the server sends is stamped with an attacker-chosen label instead of the server process\u0027s real label, so the peer\u0027s receive-side `smk_access()` check and any CIPSO-aware network enforcement are bypassed and data from a confined or high-sensitivity domain is delivered to a domain with no authorization to read it. With the built-in `@` (web) label the emitted data becomes readable by every subject, a total loss of the confidentiality control for that connection.\nI:H - Because the reply packets carry the receiver\u0027s own label, `smk_access(skp, ssp-\u003esmk_in, MAY_WRITE)` is satisfied by Smack\u0027s unconditional same-label rule, so a policy rule forbidding the server domain from writing to the client domain is completely bypassed \u2014 the commit states \"\u0027bar\u0027 can write to \u0027foo\u0027 without being authorized to write.\" Arbitrary data is injected into a MAC domain that must not be written to, a total failure of the integrity control for that flow.\nA:N - The bug causes packets to carry the wrong security label; it produces no crash, oops, hang, deadlock, or resource exhaustion. Connections continue to operate normally \u2014 indeed more permissively than policy intends."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ila: call nf_unregister_net_hooks() sooner
syzbot found an use-after-free Read in ila_nf_input [1]
Issue here is that ila_xlat_exit_net() frees the rhashtable,
then call nf_unregister_net_hooks().
It should be done in the reverse way, with a synchronize_rcu().
This is a good match for a pre_exit() method.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: emux: improve patch ioctl data validation
In load_data(), make the validation of and skipping over the main info
block match that in load_guspatch().
In load_guspatch(), add checking that the specified patch length matches
the actually supplied data, like load_data() already did.

Summary
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFER
In create_pinctrl(), pinctrl_maps_mutex is acquired before calling
add_setting(). If add_setting() returns -EPROBE_DEFER, create_pinctrl()
calls pinctrl_free(). However, pinctrl_free() attempts to acquire
pinctrl_maps_mutex, which is already held by create_pinctrl(), leading to
a potential deadlock.
This patch resolves the issue by releasing pinctrl_maps_mutex before
calling pinctrl_free(), preventing the deadlock.
This bug was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rtmutex: Drop rt_mutex::wait_lock before scheduling
rt_mutex_handle_deadlock() is called with rt_mutex::wait_lock held. In the
good case it returns with the lock held and in the deadlock case it emits a
warning and goes into an endless scheduling loop with the lock held, which
triggers the 'scheduling in atomic' warning.
Unlock rt_mutex::wait_lock in the dead lock case before issuing the warning
and dropping into the schedule for ever loop.
[ tglx: Moved unlock before the WARN(), removed the pointless comment,
massaged changelog, added Fixes tag ]

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: check dot and dotdot of dx_root before making dir indexed
Syzbot reports a issue as follows:
============================================
BUG: unable to handle page fault for address: ffffed11022e24fe
PGD 23ffee067 P4D 23ffee067 PUD 0
Oops: Oops: 0000 [#1] PREEMPT SMP KASAN PTI
CPU: 0 PID: 5079 Comm: syz-executor306 Not tainted 6.10.0-rc5-g55027e689933 #0
Call Trace:
<TASK>
make_indexed_dir+0xdaf/0x13c0 fs/ext4/namei.c:2341
ext4_add_entry+0x222a/0x25d0 fs/ext4/namei.c:2451
ext4_rename fs/ext4/namei.c:3936 [inline]
ext4_rename2+0x26e5/0x4370 fs/ext4/namei.c:4214
[...]
============================================
The immediate cause of this problem is that there is only one valid dentry
for the block to be split during do_split, so split==0 results in out of
bounds accesses to the map triggering the issue.
do_split
unsigned split
dx_make_map
count = 1
split = count/2 = 0;
continued = hash2 == map[split - 1].hash;
---> map[4294967295]
The maximum length of a filename is 255 and the minimum block size is 1024,
so it is always guaranteed that the number of entries is greater than or
equal to 2 when do_split() is called.
But syzbot's crafted image has no dot and dotdot in dir, and the dentry
distribution in dirblock is as follows:
bus dentry1 hole dentry2 free
|xx--|xx-------------|...............|xx-------------|...............|
0 12 (8+248)=256 268 256 524 (8+256)=264 788 236 1024
So when renaming dentry1 increases its name_len length by 1, neither hole
nor free is sufficient to hold the new dentry, and make_indexed_dir() is
called.
In make_indexed_dir() it is assumed that the first two entries of the
dirblock must be dot and dotdot, so bus and dentry1 are left in dx_root
because they are treated as dot and dotdot, and only dentry2 is moved
to the new leaf block. That's why count is equal to 1.
Therefore add the ext4_check_dx_root() helper function to add more sanity
checks to dot and dotdot before starting the conversion to avoid the above
issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gtp: fix a potential NULL pointer dereference
When sockfd_lookup() fails, gtp_encap_enable_socket() returns a
NULL pointer, but its callers only check for error pointers thus miss
the NULL pointer case.
Fix it by returning an error pointer with the error code carried from
sockfd_lookup().
(I found this bug during code inspection.)

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: bcm: Remove proc entry when dev is unregistered.
syzkaller reported a warning in bcm_connect() below. [0]
The repro calls connect() to vxcan1, removes vxcan1, and calls
connect() with ifindex == 0.
Calling connect() for a BCM socket allocates a proc entry.
Then, bcm_sk(sk)->bound is set to 1 to prevent further connect().
However, removing the bound device resets bcm_sk(sk)->bound to 0
in bcm_notify().
The 2nd connect() tries to allocate a proc entry with the same
name and sets NULL to bcm_sk(sk)->bcm_proc_read, leaking the
original proc entry.
Since the proc entry is available only for connect()ed sockets,
let's clean up the entry when the bound netdev is unregistered.

Summary
In the Linux kernel, the following vulnerability has been resolved:
platform/x86: toshiba_acpi: Fix array out-of-bounds access
In order to use toshiba_dmi_quirks[] together with the standard DMI
matching functions, it must be terminated by a empty entry.
Since this entry is missing, an array out-of-bounds access occurs
every time the quirk list is processed.
Fix this by adding the terminating empty entry.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bna: adjust 'name' buf size of bna_tcb and bna_ccb structures
To have enough space to write all possible sprintf() args. Currently
'name' size is 16, but the first '%s' specifier may already need at
least 16 characters, since 'bnad->netdev->name' is used there.
For '%d' specifiers, assume that they require:
* 1 char for 'tx_id + tx_info->tcb[i]->id' sum, BNAD_MAX_TXQ_PER_TX is 8
* 2 chars for 'rx_id + rx_info->rx_ctrl[i].ccb->id', BNAD_MAX_RXP_PER_RX
is 16
And replace sprintf with snprintf.
Detected using the static analysis tool - Svace.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: rswitch: Avoid use-after-free in rswitch_poll()
The use-after-free is actually in rswitch_tx_free(), which is inlined in
rswitch_poll(). Since `skb` and `gq->skbs[gq->dirty]` are in fact the
same pointer, the skb is first freed using dev_kfree_skb_any(), then the
value in skb->len is used to update the interface statistics.
Let's move around the instructions to use skb->len before the skb is
freed.
This bug is trivial to reproduce using KFENCE. It will trigger a splat
every few packets. A simple ARP request or ICMP echo request is enough.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Skip finding free audio for unknown engine_id
[WHY]
ENGINE_ID_UNKNOWN = -1 and can not be used as an array index. Plus, it
also means it is uninitialized and does not need free audio.
[HOW]
Skip and return NULL.
This fixes 2 OVERRUN issues reported by Coverity.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Avoid uninitialized value in BPF_CORE_READ_BITFIELD
[Changes from V1:
- Use a default branch in the switch statement to initialize `val'.]
GCC warns that `val' may be used uninitialized in the
BPF_CRE_READ_BITFIELD macro, defined in bpf_core_read.h as:
[...]
unsigned long long val; \
[...] \
switch (__CORE_RELO(s, field, BYTE_SIZE)) { \
case 1: val = *(const unsigned char *)p; break; \
case 2: val = *(const unsigned short *)p; break; \
case 4: val = *(const unsigned int *)p; break; \
case 8: val = *(const unsigned long long *)p; break; \
} \
[...]
val; \
} \
This patch adds a default entry in the switch statement that sets
`val' to zero in order to avoid the warning, and random values to be
used in case __builtin_preserve_field_info returns unexpected values
for BPF_FIELD_BYTE_SIZE.
Tested in bpf-next master.
No regressions.

"value": "AV:L - The vulnerability is reached by mounting a crafted JFS image and then unlinking a file, all through local syscalls (mount/unlink) on a block or loop device. No network protocol processing is involved.\nAC:L - The out-of-bounds index is taken verbatim from the on-disk `iagp-\u003eagstart` field, so the attacker picks the exact OOB offset deterministically in the image; there is no race and no reliance on conditions outside attacker control.\nPR:L - A low-privileged local user can supply the malicious JFS image on common desktop/kiosk configurations where udisks2/polkit permits an active session user to mount removable or loop-backed media, and the subsequent unlink that triggers `diFree` requires only ordinary write access to a directory on that filesystem.\nUI:N - Once the image is attached, no victim action is needed \u2014 the attacker\u0027s own unlink drives `jfs_evict_inode` into `diFree`, and automounters attach the media without any human step.\nS:U - The corruption stays within kernel memory under the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The unchecked index produces out-of-bounds reads of `im_agctl[agno].numfree`/`numinos` and of the `im_aglock[agno]` mutex at an attacker-chosen offset, and the resulting heap corruption is a general primitive that can be leveraged for kernel memory disclosure.\nI:H - `imap-\u003eim_agctl[agno].inofree = iagno` writes an attacker-influenced 32-bit value at an attacker-chosen offset far outside the `struct inomap` allocation, and `mutex_lock()` on `im_aglock[agno]` writes a kernel pointer OOB \u2014 a controlled slab-corruption write primitive suitable for control-flow hijacking.\nA:H - Out-of-bounds writes into adjacent slab objects and locking a bogus mutex reliably produce oopses, hangs, or panics, and an OOB-read `numinos` of zero yields an immediate divide-error in the `(numfree * 100) / numinos` computation."

Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: fix use-after-free on failed backlog decryption
When the decrypt request goes to the backlog and crypto_aead_decrypt
returns -EBUSY, tls_do_decryption will wait until all async
decryptions have completed. If one of them fails, tls_do_decryption
will return -EBADMSG and tls_decrypt_sg jumps to the error path,
releasing all the pages. But the pages have been passed to the async
callback, and have already been released by tls_decrypt_done.
The only true async case is when crypto_aead_decrypt returns
-EINPROGRESS. With -EBUSY, we already waited so we can tell
tls_sw_recvmsg that the data is available for immediate copy, but we
need to notify tls_decrypt_sg (via the new ->async_done flag) that the
memory has already been released.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/dpaa2: Avoid explicit cpumask var allocation on stack
For CONFIG_CPUMASK_OFFSTACK=y kernel, explicit allocation of cpumask
variable on stack is not recommended since it can cause potential stack
overflow.
Instead, kernel code should always use *cpumask_var API(s) to allocate
cpumask var in config-neutral way, leaving allocation strategy to
CONFIG_CPUMASK_OFFSTACK.
Use *cpumask_var API(s) to address it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tipc: Return non-zero value from tipc_udp_addr2str() on error
tipc_udp_addr2str() should return non-zero value if the UDP media
address is invalid. Otherwise, a buffer overflow access can occur in
tipc_media_addr_printf(). Fix this by returning 1 on an invalid UDP
media address.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86: stop playing stack games in profile_pc()
The 'profile_pc()' function is used for timer-based profiling, which
isn't really all that relevant any more to begin with, but it also ends
up making assumptions based on the stack layout that aren't necessarily
valid.
Basically, the code tries to account the time spent in spinlocks to the
caller rather than the spinlock, and while I support that as a concept,
it's not worth the code complexity or the KASAN warnings when no serious
profiling is done using timers anyway these days.
And the code really does depend on stack layout that is only true in the
simplest of cases. We've lost the comment at some point (I think when
the 32-bit and 64-bit code was unified), but it used to say:
Assume the lock function has either no stack frame or a copy
of eflags from PUSHF.
which explains why it just blindly loads a word or two straight off the
stack pointer and then takes a minimal look at the values to just check
if they might be eflags or the return pc:
Eflags always has bits 22 and up cleared unlike kernel addresses
but that basic stack layout assumption assumes that there isn't any lock
debugging etc going on that would complicate the code and cause a stack
frame.
It causes KASAN unhappiness reported for years by syzkaller [1] and
others [2].
With no real practical reason for this any more, just remove the code.
Just for historical interest, here's some background commits relating to
this code from 2006:
0cb91a229364 ("i386: Account spinlocks to the caller during profiling for !FP kernels")
31679f38d886 ("Simplify profile_pc on x86-64")
and a code unification from 2009:
ef4512882dbe ("x86: time_32/64.c unify profile_pc")
but the basics of this thing actually goes back to before the git tree.

We\u0027ve lost the comment at some point (I think when\nthe 32-bit and 64-bit code was unified), but it used to say:\n\n\tAssume the lock function has either no stack frame or a copy\n\tof eflags from PUSHF.\n\nwhich explains why it just blindly loads a word or two straight off the\nstack pointer and then takes a minimal look at the values to just check\nif they might be eflags or the return pc:\n\n\tEflags always has bits 22 and up cleared unlike kernel addresses\n\nbut that basic stack layout assumption assumes that there isn\u0027t any lock\ndebugging etc going on that would complicate the code and cause a stack\nframe.\n\nIt causes KASAN unhappiness reported for years by syzkaller [1] and\nothers [2].\n\nWith no real practical reason for this any more, just remove the code.\n\nJust for historical interest, here\u0027s some background commits relating to\nthis code from 2006:\n\n 0cb91a229364 (\"i386: Account spinlocks to the caller during profiling for !FP kernels\")\n 31679f38d886 (\"Simplify profile_pc on x86-64\")\n\nand a code unification from 2009:\n\n ef4512882dbe (\"x86: time_32/64.c unify profile_pc\")\n\nbut the basics of this thing actually goes back to before the git tree."

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/mm: Fix pti_clone_pgtable() alignment assumption
Guenter reported dodgy crashes on an i386-nosmp build using GCC-11
that had the form of endless traps until entry stack exhaust and then
#DF from the stack guard.
It turned out that pti_clone_pgtable() had alignment assumptions on
the start address, notably it hard assumes start is PMD aligned. This
is true on x86_64, but very much not true on i386.
These assumptions can cause the end condition to malfunction, leading
to a 'short' clone. Guess what happens when the user mapping has a
short copy of the entry text?
Use the correct increment form for addr to avoid alignment
assumptions.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/lima: fix shared irq handling on driver remove
lima uses a shared interrupt, so the interrupt handlers must be prepared
to be called at any time. At driver removal time, the clocks are
disabled early and the interrupts stay registered until the very end of
the remove process due to the devm usage.
This is potentially a bug as the interrupts access device registers
which assumes clocks are enabled. A crash can be triggered by removing
the driver in a kernel with CONFIG_DEBUG_SHIRQ enabled.
This patch frees the interrupts at each lima device finishing callback
so that the handlers are already unregistered by the time we fully
disable clocks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvmet: always initialize cqe.result
The spec doesn't mandate that the first two double words (aka results)
for the command queue entry need to be set to 0 when they are not
used (not specified). Though, the target implemention returns 0 for TCP
and FC but not for RDMA.
Let's make RDMA behave the same and thus explicitly initializing the
result field. This prevents leaking any data from the stack.

Summary
In the Linux kernel, the following vulnerability has been resolved:
udf: Avoid excessive partition lengths
Avoid mounting filesystems where the partition would overflow the
32-bits used for block number. Also refuse to mount filesystems where
the partition length is so large we cannot safely index bits in a
block bitmap.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: restore set elements when delete set fails
From abort path, nft_mapelem_activate() needs to restore refcounters to
the original state. Currently, it uses the set->ops->walk() to iterate
over these set elements. The existing set iterator skips inactive
elements in the next generation, this does not work from the abort path
to restore the original state since it has to skip active elements
instead (not inactive ones).
This patch moves the check for inactive elements to the set iterator
callback, then it reverses the logic for the .activate case which
needs to skip active elements.
Toggle next generation bit for elements when delete set command is
invoked and call nft_clear() from .activate (abort) path to restore the
next generation bit.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvmet: fix a possible leak when destroy a ctrl during qp establishment
In nvmet_sq_destroy we capture sq->ctrl early and if it is non-NULL we
know that a ctrl was allocated (in the admin connect request handler)
and we need to release pending AERs, clear ctrl->sqs and sq->ctrl
(for nvme-loop primarily), and drop the final reference on the ctrl.
However, a small window is possible where nvmet_sq_destroy starts (as
a result of the client giving up and disconnecting) concurrently with
the nvme admin connect cmd (which may be in an early stage). But *before*
kill_and_confirm of sq->ref (i.e. the admin connect managed to get an sq
live reference). In this case, sq->ctrl was allocated however after it was
captured in a local variable in nvmet_sq_destroy.
This prevented the final reference drop on the ctrl.
Solve this by re-capturing the sq->ctrl after all inflight request has
completed, where for sure sq->ctrl reference is final, and move forward
based on that.
This issue was observed in an environment with many hosts connecting
multiple ctrls simoutanuosly, creating a delay in allocating a ctrl
leading up to this race window.

The vulnerable component is a network-bound storage target (NVMe-oF over RDMA/RoCEv2/iWARP/FC), reachable purely over the fabric with no local access.\nAC:L - The attacker controls both sides of the race \u2014 it sends the admin Connect capsule and then immediately tears down the connection (rdma_disconnect/CM DREQ), and can retry in a tight loop from many parallel connections. The commit itself notes the window widens when many hosts connect simultaneously (delaying `nvmet_alloc_ctrl()`), a condition an attacker deliberately reproduces by flooding the target with concurrent connects.\nPR:N - The Connect command is the pre-authentication handshake itself, and `nvmet_host_allowed()` returns true unconditionally for the discovery subsystem (\"allow all access to disc subsys\"), while NVM subsystems are commonly deployed with `attr_allow_any_host=1`; DH-CHAP is optional and off by default. An unauthenticated remote peer can therefore reach `nvmet_alloc_ctrl()` and allocate a controller with no credentials.\nUI:N - The attacker\u0027s own initiator performs both the Connect and the disconnect; no victim action, mount, or administrator interaction is required.\nS:U - The leaked `nvmet_ctrl` and the resulting resource exhaustion are confined to the kernel of the target host; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - `ctrl-\u003esqs[]` entries are only compared and assigned, never dereferenced, so the stale pointers left behind produce no read of freed memory, and nothing from the leaked controller is returned to the attacker.\nI:N - No memory is corrupted and no data is modified \u2014 the missing `nvmet_ctrl_put()` only skips a reference drop and leaves `sq-\u003ectrl`/`ctrl-\u003esqs[qid]` uncleared, yielding no write primitive.\nA:H - Every won race permanently leaks a `nvmet_ctrl` (controller struct, 4 KB `changed_ns_list`, `sqs` array, subsystem reference, and a `cntlid_ida` entry), and the zombie controller stays on `subsys-\u003ectrls` accumulating `nvmet_async_event` allocations forever, so an unauthenticated peer can repeat it without limit to exhaust kernel memory. Exhausting the 65519-entry cntlid range additionally makes `nvmet_alloc_ctrl()` fail with CONNECT_CTRL_BUSY, denying all new connections and blocking subsystem teardown \u2014 a persistent, complete denial of the storage service until reboot."

Summary
In the Linux kernel, the following vulnerability has been resolved:
netem: fix return value if duplicate enqueue fails
There is a bug in netem_enqueue() introduced by
commit 5845f706388a ("net: netem: fix skb length BUG_ON in __skb_to_sgvec")
that can lead to a use-after-free.
This commit made netem_enqueue() always return NET_XMIT_SUCCESS
when a packet is duplicated, which can cause the parent qdisc's q.qlen
to be mistakenly incremented. When this happens qlen_notify() may be
skipped on the parent during destruction, leaving a dangling pointer
for some classful qdiscs like DRR.
There are two ways for the bug happen:
- If the duplicated packet is dropped by rootq->enqueue() and then
the original packet is also dropped.
- If rootq->enqueue() sends the duplicated packet to a different qdisc
and the original packet is dropped.
In both cases NET_XMIT_SUCCESS is returned even though no packets
are enqueued at the netem qdisc.
The fix is to defer the enqueue of the duplicate packet until after
the original packet has been guaranteed to return NET_XMIT_SUCCESS.

This requires local system access, matching the tc/netlink qdisc guidance.\nAC:L - The attacker fully controls both trigger conditions \u2014 netem\u0027s `duplicate` probability (settable to 100%) and its `limit` \u2014 so the bogus NET_XMIT_SUCCESS is produced deterministically on every enqueue, with no race to win and no reliance on state outside the attacker\u0027s control.\nPR:L - Qdisc and class configuration requires CAP_NET_ADMIN, but the check is `netlink_net_capable()` against the netns owner user_ns, so any unprivileged user obtains it inside `unshare -Urn` along with a dummy/veth device to attach the qdiscs to.\nUI:N - The attacker performs every step \u2014 qdisc setup, packet transmission, class deletion, and the subsequent dequeue that touches freed memory \u2014 with no victim action required.\nS:U - The corruption occurs in kernel heap memory within the same host security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - The freed `struct drr_class` remains linked in `q-\u003eactive` and is dereferenced on dequeue (`cl-\u003eqdisc-\u003eops-\u003epeek`, `cl-\u003edeficit`), so reclaiming the slab object lets the attacker read arbitrary kernel memory through the attacker-controlled `cl-\u003eqdisc` pointer.\nI:H - The use-after-free yields a write primitive via `list_del`/`list_move_tail` into the freed object and a controlled function-pointer call through `cl-\u003eqdisc-\u003eops-\u003epeek`, which is sufficient for control-flow hijack and privilege escalation.\nA:H - Even without successful exploitation the dangling `drr_class` pointer causes an oops/panic on the next dequeue, and the desynchronized parent q.qlen corrupts scheduler state, reliably crashing the kernel."

Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: uinput - reject requests with unreasonable number of slots
When exercising uinput interface syzkaller may try setting up device
with a really large number of slots, which causes memory allocation
failure in input_mt_init_slots(). While this allocation failure is
handled properly and request is rejected, it results in syzkaller
reports. Additionally, such request may put undue burden on the
system which will try to free a lot of memory for a bogus request.
Fix it by limiting allowed number of slots to 100. This can easily
be extended if we see devices that can track more than 100 contacts.

[ 53.392750] ret_from_fork+0x10/0x20
The issue here is as follows:
- tidss probes, but is deferred as sii902x is still missing.
- sii902x starts probing and enters sii902x_init().
- sii902x calls drm_bridge_add(). Now the sii902x bridge is ready from
DRM's perspective.
- sii902x calls sii902x_audio_codec_init() and
platform_device_register_data()
- The registration of the audio platform device causes probing of the
deferred devices.
- tidss probes, which eventually causes sii902x_bridge_get_edid() to be
called.
- sii902x_bridge_get_edid() tries to use the i2c to read the edid.
However, the sii902x driver has not set up the i2c part yet, leading
to the crash.
Fix this by moving the drm_bridge_add() to the end of the
sii902x_init(), which is also at the very end of sii902x_probe().

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: core: check uartclk for zero to avoid divide by zero
Calling ioctl TIOCSSERIAL with an invalid baud_base can
result in uartclk being zero, which will result in a
divide by zero error in uart_get_divisor(). The check for
uartclk being zero in uart_set_info() needs to be done
before other settings are made as subsequent calls to
ioctl TIOCSSERIAL for the same port would be impacted if
the uartclk check was done where uartclk gets set.
Oops: divide error: 0000 PREEMPT SMP KASAN PTI

Summary
In the Linux kernel, the following vulnerability has been resolved:
pci/hotplug/pnv_php: Fix hotplug driver crash on Powernv
The hotplug driver for powerpc (pci/hotplug/pnv_php.c) causes a kernel
crash when we try to hot-unplug/disable the PCIe switch/bridge from
the PHB.
The crash occurs because although the MSI data structure has been
released during disable/hot-unplug path and it has been assigned
with NULL, still during unregistration the code was again trying to
explicitly disable the MSI which causes the NULL pointer dereference and
kernel crash.
The patch fixes the check during unregistration path to prevent invoking
pci_disable_msi/msix() since its data structure is already freed.

This is the switch-driver equivalent of WiFi/Bluetooth-class adjacency rather than routable network reach.\nAC:L - Both preconditions are created by the attacker\u0027s own frames \u2014 MAC flooding to fill a 4-entry ATU bin is trivial and deterministic, and each new multicast group join forces a fresh CPU ATU Load that hits the full bin, reliably yielding SPID=0xF. No race, no memory-layout luck, and the handler runs in both hardware-IRQ and 100 ms polling modes.\nPR:N - The attacker only needs to emit raw Ethernet frames and IGMP reports on the switch segment; no account, credential, capability, or authentication on the target device is involved. The bridge\u0027s default multicast snooping performs the privileged ATU load on the attacker\u0027s behalf.\nUI:N - The attacker\u0027s own transmitted frames drive both the ATU fill and the MDB offload that causes the violation interrupt. No administrator or user action on the target is required.\nS:U - The out-of-bounds increment corrupts kernel heap memory within the same kernel security authority as the DSA driver. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The out-of-bounds access is a read-modify-write past the end of `chip-\u003eports[]`, and the repeatable increment primitive can be aimed at adjacent length, index, or pointer fields (e.g. `fid_bitmap`, `regions[]`, the `msts` list_head, or a neighbouring slab object) to turn the corruption into out-of-bounds reads and kernel memory disclosure.\nI:H - This is an out-of-bounds write of a 64-bit word at a fixed offset beyond the array, and because the attacker can force the increment an unbounded number of times, an adjacent pointer, counter, or refcount can be driven to an arbitrary value \u2014 a genuine heap corruption primitive, not a benign miscount.\nA:H - Corrupting `msts`/`regions[]` pointers, the FID allocation bitmap, or an adjacent slab object leads to oops, panic, or list corruption on the next traversal, and the attacker can repeat the write indefinitely from the LAN. On the embedded, automotive, and industrial gateways where mv88e6xxx switches are deployed this is a repeatable full denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/panel: ilitek-ili9881c: Fix warning with GPIO controllers that sleep
The ilitek-ili9881c controls the reset GPIO using the non-sleeping
gpiod_set_value() function. This complains loudly when the GPIO
controller needs to sleep. As the caller can sleep, use
gpiod_set_value_cansleep() to fix the issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
apparmor: fix possible NULL pointer dereference
profile->parent->dents[AAFS_PROF_DIR] could be NULL only if its parent is made
from __create_missing_ancestors(..) and 'ent->old' is NULL in
aa_replace_profiles(..).
In that case, it must return an error code and the code, -ENOENT represents
its state that the path of its parent is not existed yet.

Summary
In the Linux kernel, the following vulnerability has been resolved:
udf: Avoid using corrupted block bitmap buffer
When the filesystem block bitmap is corrupted, we detect the corruption
while loading the bitmap and fail the allocation with error. However the
next allocation from the same bitmap will notice the bitmap buffer is
already loaded and tries to allocate from the bitmap with mixed results
(depending on the exact nature of the bitmap corruption). Fix the
problem by using BH_verified bit to indicate whether the bitmap is valid
or not.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: fix crashes from deferred split racing folio migration
Even on 6.10-rc6, I've been seeing elusive "Bad page state"s (often on
flags when freeing, yet the flags shown are not bad: PG_locked had been
set and cleared??), and VM_BUG_ON_PAGE(page_ref_count(page) == 0)s from
deferred_split_scan()'s folio_put(), and a variety of other BUG and WARN
symptoms implying double free by deferred split and large folio migration.
6.7 commit 9bcef5973e31 ("mm: memcg: fix split queue list crash when large
folio migration") was right to fix the memcg-dependent locking broken in
85ce2c517ade ("memcontrol: only transfer the memcg data for migration"),
but missed a subtlety of deferred_split_scan(): it moves folios to its own
local list to work on them without split_queue_lock, during which time
folio->_deferred_list is not empty, but even the "right" lock does nothing
to secure the folio and the list it is on.
Fortunately, deferred_split_scan() is careful to use folio_try_get(): so
folio_migrate_mapping() can avoid the race by folio_undo_large_rmappable()
while the old folio's reference count is temporarily frozen to 0 - adding
such a freeze in the !mapping case too (originally, folio lock and
unmapping and no swap cache left an anon folio unreachable, so no freezing
was needed there: but the deferred split queue offers a way to reach it).

There is no IP-network-facing consumer of this code.\nAC:L - The attacker deterministically arms the path by issuing two back-to-back `sendmsg()` calls so `bchannel_senddata()` sets `FLG_TX_NEXT`/`next_skb` (or `dchannel_senddata()` queues to `squeue`), guaranteeing `get_next_bframe()`/`get_next_dframe()` returns 1 and the post-free dereference executes. All call sites hold `hc-\u003elock`, so there is no race to win and no memory-layout precondition.\nPR:L - `data_sock_create()` performs no `capable()` check \u2014 only `base_sock_create()` (ISDN_P_BASE/SOCK_RAW) requires `CAP_NET_RAW` \u2014 and `data_sock_bind()`/`connect_Bstack()` add no further gate, so any unprivileged local user can bind a B- or D-channel and drive the transmit path.\nUI:N - The attacker performs every step itself \u2014 socket, bind, PH_ACTIVATE_REQ, then the two queued sends \u2014 with no action required from an administrator or any other user.\nS:U - The freed object is a kernel `sk_buff` and any corruption stays within the kernel\u0027s own security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - Per the published use-after-free, the stale `(*sp)-\u003elen` sizes a `write_fifo()` read from `(*sp)-\u003edata`, pushing freed-heap contents out onto the ISDN B-/D-channel to the far end of the line; heap grooming of the reclaimed skb makes this a controllable kernel-memory disclosure.\nI:H - A use-after-free lets the attacker reclaim the freed `sk_buff` with attacker-shaped data, so the `len` and `data` fields consumed afterwards become attacker-controlled, yielding a write/pointer primitive usable for control-flow hijacking.\nA:H - Dereferencing a freed skb and DMAing/PIO-ing from a dangling `data` pointer readily oopses or panics the kernel, and the sequence can be repeated at will from an unprivileged process."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check index msg_id before read or write
[WHAT]
msg_id is used as an array index and it cannot be a negative value, and
therefore cannot be equal to MOD_HDCP_MESSAGE_ID_INVALID (-1).
[HOW]
Check whether msg_id is valid before reading and setting.
This fixes 4 OVERRUN issues reported by Coverity.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: handle inconsistent state in nilfs_btnode_create_block()
Syzbot reported that a buffer state inconsistency was detected in
nilfs_btnode_create_block(), triggering a kernel bug.
It is not appropriate to treat this inconsistency as a bug; it can occur
if the argument block address (the buffer index of the newly created
block) is a virtual block number and has been reallocated due to
corruption of the bitmap used to manage its allocation state.
So, modify nilfs_btnode_create_block() and its callers to treat it as a
possible filesystem error, rather than triggering a kernel bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gtp: pull network headers in gtp_dev_xmit()
syzbot/KMSAN reported use of uninit-value in get_dev_xmit() [1]
We must make sure the IPv4 or Ipv6 header is pulled in skb->head
before accessing fields in them.
Use pskb_inet_may_pull() to fix this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio_net: Fix napi_skb_cache_put warning
After the commit bdacf3e34945 ("net: Use nested-BH locking for
napi_alloc_cache.") was merged, the following warning began to appear:
WARNING: CPU: 5 PID: 1 at net/core/skbuff.c:1451 napi_skb_cache_put+0x82/0x4b0
__warn+0x12f/0x340

__free_old_xmit+0x1c8/0x510
__free_old_xmit+0x1c8/0x510
__pfx___free_old_xmit+0x10/0x10
The issue arises because virtio is assuming it's running in NAPI context
even when it's not, such as in the netpoll case.
To resolve this, modify virtnet_poll_tx() to only set NAPI when budget
is available. Same for virtnet_poll_cleantx(), which always assumed that
it was in a NAPI context.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: ecdh - explicitly zeroize private_key
private_key is overwritten with the key parameter passed in by the
caller (if present), or alternatively a newly generated private key.
However, it is possible that the caller provides a key (or the newly
generated key) which is shorter than the previous key. In that
scenario, some key material from the previous key would not be
overwritten. The easiest solution is to explicitly zeroize the entire
private_key array first.
Note that this patch slightly changes the behavior of this function:
previously, if the ecc_gen_privkey failed, the old private_key would
remain. Now, the private_key is always zeroized. This behavior is
consistent with the case where params.key is set and ecc_is_key_valid
fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: venus: fix use after free in vdec_close
There appears to be a possible use after free with vdec_close().
The firmware will add buffer release work to the work queue through
HFI callbacks as a normal part of decoding. Randomly closing the
decoder device from userspace during normal decoding can incur
a read after free for inst.
Fix it by cancelling the work in vdec_close.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: can: j1939: enhanced error handling for tightly received RTS messages in xtp_rx_rts_session_new
This patch enhances error handling in scenarios with RTS (Request to
Send) messages arriving closely. It replaces the less informative WARN_ON_ONCE
backtraces with a new error handling method. This provides clearer error
messages and allows for the early termination of problematic sessions.
Previously, sessions were only released at the end of j1939_xtp_rx_rts().
Potentially this could be reproduced with something like:
testj1939 -r vcan0:0x80 &
while true; do
# send first RTS
cansend vcan0 18EC8090#1014000303002301;
# send second RTS
cansend vcan0 18EC8090#1014000303002301;
# send abort
cansend vcan0 18EC8090#ff00000000002301;
done

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: prevent UAF in ip6_send_skb()
syzbot reported an UAF in ip6_send_skb() [1]
After ip6_local_out() has returned, we no longer can safely
dereference rt, unless we hold rcu_read_lock().
A similar issue has been fixed in commit
a688caa34beb ("ipv6: take rcu lock in rawv6_send_hdrinc()")
Another potential issue in ip6_finish_output2() is handled in a
separate patch.

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/mm: Add NULL pointer check to crst_table_free() base_crst_free()
crst_table_free() used to work with NULL pointers before the conversion
to ptdescs. Since crst_table_free() can be called with a NULL pointer
(error handling in crst_table_upgrade() add an explicit check.
Also add the same check to base_crst_free() for consistency reasons.
In real life this should not happen, since order two GFP_KERNEL
allocations will not fail, unless FAIL_PAGE_ALLOC is enabled and used.

Summary
In the Linux kernel, the following vulnerability has been resolved:
exec: Fix ToCToU between perm check and set-uid/gid usage
When opening a file for exec via do_filp_open(), permission checking is
done against the file's metadata at that moment, and on success, a file
pointer is passed back. Much later in the execve() code path, the file
metadata (specifically mode, uid, and gid) is used to determine if/how
to set the uid and gid. However, those values may have changed since the
permissions check, meaning the execution may gain unintended privileges.
For example, if a file could change permissions from executable and not
set-id:
---------x 1 root root 16048 Aug 7 13:16 target
to set-id and non-executable:
---S------ 1 root root 16048 Aug 7 13:16 target
it is possible to gain root privileges when execution should have been
disallowed.
While this race condition is rare in real-world scenarios, it has been
observed (and proven exploitable) when package managers are updating
the setuid bits of installed programs. Such files start with being
world-executable but then are adjusted to be group-exec with a set-uid
bit. For example, "chmod o-x,u+s target" makes "target" executable only
by uid "root" and gid "cdrom", while also becoming setuid-root:
-rwxr-xr-x 1 root cdrom 16048 Aug 7 13:16 target
becomes:
-rwsr-xr-- 1 root cdrom 16048 Aug 7 13:16 target
But racing the chmod means users without group "cdrom" membership can
get the permission to execute "target" just before the chmod, and when
the chmod finishes, the exec reaches brpm_fill_uid(), and performs the
setuid to root, violating the expressed authorization of "only cdrom
group members can setuid to root".
Re-check that we still have execute permissions in case the metadata
has changed. It would be better to keep a copy from the perm-check time,
but until we can do that refactoring, the least-bad option is to do a
full inode_permission() call (under inode lock). It is understood that
this is safe against dead-locks, but hardly optimal.

Much later in the execve() code path, the file\nmetadata (specifically mode, uid, and gid) is used to determine if/how\nto set the uid and gid. However, those values may have changed since the\npermissions check, meaning the execution may gain unintended privileges.\n\nFor example, if a file could change permissions from executable and not\nset-id:\n\n---------x 1 root root 16048 Aug 7 13:16 target\n\nto set-id and non-executable:\n\n---S------ 1 root root 16048 Aug 7 13:16 target\n\nit is possible to gain root privileges when execution should have been\ndisallowed.\n\nWhile this race condition is rare in real-world scenarios, it has been\nobserved (and proven exploitable) when package managers are updating\nthe setuid bits of installed programs. Such files start with being\nworld-executable but then are adjusted to be group-exec with a set-uid\nbit. For example, \"chmod o-x,u+s target\" makes \"target\" executable only\nby uid \"root\" and gid \"cdrom\", while also becoming setuid-root:\n\n-rwxr-xr-x 1 root cdrom 16048 Aug 7 13:16 target\n\nbecomes:\n\n-rwsr-xr-- 1 root cdrom 16048 Aug 7 13:16 target\n\nBut racing the chmod means users without group \"cdrom\" membership can\nget the permission to execute \"target\" just before the chmod, and when\nthe chmod finishes, the exec reaches brpm_fill_uid(), and performs the\nsetuid to root, violating the expressed authorization of \"only cdrom\ngroup members can setuid to root\".\n\nRe-check that we still have execute permissions in case the metadata\nhas changed. It would be better to keep a copy from the perm-check time,\nbut until we can do that refactoring, the least-bad option is to do a\nfull inode_permission() call (under inode lock). It is understood that\nthis is safe against dead-locks, but hardly optimal."

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: swap: fix race between free_swap_and_cache() and swapoff()
There was previously a theoretical window where swapoff() could run and
teardown a swap_info_struct while a call to free_swap_and_cache() was
running in another thread. This could cause, amongst other bad
possibilities, swap_page_trans_huge_swapped() (called by
free_swap_and_cache()) to access the freed memory for swap_map.
This is a theoretical problem and I haven't been able to provoke it from a
test case. But there has been agreement based on code review that this is
possible (see link below).
Fix it by using get_swap_device()/put_swap_device(), which will stall
swapoff(). There was an extra check in _swap_info_get() to confirm that
the swap entry was not free. This isn't present in get_swap_device()
because it doesn't make sense in general due to the race between getting
the reference and swapoff. So I've added an equivalent check directly in
free_swap_and_cache().
Details of how to provoke one possible issue (thanks to David Hildenbrand
for deriving this):
--8<-----
__swap_entry_free() might be the last user and result in
"count == SWAP_HAS_CACHE".
swapoff->try_to_unuse() will stop as soon as soon as si->inuse_pages==0.
So the question is: could someone reclaim the folio and turn
si->inuse_pages==0, before we completed swap_page_trans_huge_swapped().
Imagine the following: 2 MiB folio in the swapcache. Only 2 subpages are
still references by swap entries.
Process 1 still references subpage 0 via swap entry.
Process 2 still references subpage 1 via swap entry.
Process 1 quits. Calls free_swap_and_cache().
-> count == SWAP_HAS_CACHE
[then, preempted in the hypervisor etc.]
Process 2 quits. Calls free_swap_and_cache().
-> count == SWAP_HAS_CACHE
Process 2 goes ahead, passes swap_page_trans_huge_swapped(), and calls
__try_to_reclaim_swap().
__try_to_reclaim_swap()->folio_free_swap()->delete_from_swap_cache()->
put_swap_folio()->free_swap_slot()->swapcache_free_entries()->
swap_entry_free()->swap_range_free()->
...
WRITE_ONCE(si->inuse_pages, si->inuse_pages - nr_entries);
What stops swapoff to succeed after process 2 reclaimed the swap cache
but before process1 finished its call to swap_page_trans_huge_swapped()?

This could cause, amongst other bad\npossibilities, swap_page_trans_huge_swapped() (called by\nfree_swap_and_cache()) to access the freed memory for swap_map.\n\nThis is a theoretical problem and I haven\u0027t been able to provoke it from a\ntest case. But there has been agreement based on code review that this is\npossible (see link below).\n\nFix it by using get_swap_device()/put_swap_device(), which will stall\nswapoff(). There was an extra check in _swap_info_get() to confirm that\nthe swap entry was not free. This isn\u0027t present in get_swap_device()\nbecause it doesn\u0027t make sense in general due to the race between getting\nthe reference and swapoff. So I\u0027ve added an equivalent check directly in\nfree_swap_and_cache().\n\nDetails of how to provoke one possible issue (thanks to David Hildenbrand\nfor deriving this):\n\n--8\u003c-----\n\n__swap_entry_free() might be the last user and result in\n\"count == SWAP_HAS_CACHE\".\n\nswapoff-\u003etry_to_unuse() will stop as soon as soon as si-\u003einuse_pages==0.\n\nSo the question is: could someone reclaim the folio and turn\nsi-\u003einuse_pages==0, before we completed swap_page_trans_huge_swapped().\n\nImagine the following: 2 MiB folio in the swapcache. Only 2 subpages are\nstill references by swap entries.\n\nProcess 1 still references subpage 0 via swap entry.\nProcess 2 still references subpage 1 via swap entry.\n\nProcess 1 quits. Calls free_swap_and_cache().\n-\u003e count == SWAP_HAS_CACHE\n[then, preempted in the hypervisor etc.]\n\nProcess 2 quits. Calls free_swap_and_cache().\n-\u003e count == SWAP_HAS_CACHE\n\nProcess 2 goes ahead, passes swap_page_trans_huge_swapped(), and calls\n__try_to_reclaim_swap().\n\n__try_to_reclaim_swap()-\u003efolio_free_swap()-\u003edelete_from_swap_cache()-\u003e\nput_swap_folio()-\u003efree_swap_slot()-\u003eswapcache_free_entries()-\u003e\nswap_entry_free()-\u003eswap_range_free()-\u003e\n...\nWRITE_ONCE(si-\u003einuse_pages, si-\u003einuse_pages - nr_entries);\n\nWhat stops swapoff to succeed after process 2 reclaimed the swap cache\nbut before process1 finished its call to swap_page_trans_huge_swapped()?\n\n--8\u003c-----"

"value": "AV:L - The vulnerable path is reached only through local memory-management syscalls \u2014 `munmap`/`exit` (`zap_pte_range` \u2192 mm/memory.c:1636), `madvise(MADV_DONTNEED/MADV_FREE)` (mm/madvise.c:659), and tmpfs truncate/punch-hole (mm/shmem.c:842). No remote or adjacent-network consumer reaches `free_swap_and_cache()`.\nAC:H - The attacker controls only their half of the race; the other half is `swapoff()`, gated by `capable(CAP_SYS_ADMIN)` in the *initial* user namespace (mm/swapfile.c:2411, `capable()` not `ns_capable()`), so it cannot be induced from a user namespace and must be performed by an administrator or system script. Landing the hit additionally requires being preempted inside a sub-microsecond window between `__swap_entry_free()` and `swap_page_trans_huge_swapped()` while a second process reclaims the last swapcache reference \u2014 the author explicitly could not provoke it from a test case.\nPR:L - The attacker-controlled side needs nothing beyond an ordinary unprivileged local account: any process can spin `munmap`/`madvise`/tmpfs-punch loops over swapped-out anonymous pages to drive `free_swap_and_cache()` at high rate. No capability, namespace, or filesystem privilege is required for that half.\nUI:N - No victim is tricked into any action; the required `swapoff()` is routine system activity (systemd swap-unit deactivation, hibernate scripts, Android zram reconfiguration) that occurs without human participation, and that environmental dependency is already accounted for in AC:H rather than counted twice as UI:R.\nS:U - The corruption is confined to kernel data structures within the kernel\u0027s own security authority \u2014 standard local kernel memory corruption / privilege escalation. No VM, hypervisor, or IOMMU boundary is crossed.\nC:H - Use-after-free reads of the vfree\u0027d `swap_map`, the kvfree\u0027d `cluster_info`, and a freed `struct address_space` (XArray walk in `filemap_get_folio()`) can disclose reallocated kernel memory. Additionally, `swapoff`+`swapon` reuses the `swap_info_struct` slot, so the stale `free_swap_and_cache()` corrupts the *new* device\u0027s counts and prematurely frees slots still referenced by other processes, handing a victim\u0027s swapped-out anonymous data to the attacker on swap-in.\nI:H - `lock_cluster()` performs `spin_lock(\u0026ci-\u003elock)` on the kvfree\u0027d `cluster_info` \u2014 for typical swap sizes a kmalloc-slab object \u2014 giving a sprayable use-after-free *write* primitive, and `__try_to_reclaim_swap()` manipulates folio locks/refcounts derived from a freed `address_space`. Combined with silent swap-map count corruption after `swapon` reuse, this is exploitable for control-flow hijack and cross-process data modification.\nA:H - The most likely immediate outcome is a kernel oops \u2014 dereferencing a NULLed `si-\u003eswap_map`, faulting in the unmapped vfree\u0027d vmalloc range, a NULL `swapper_spaces[type]`, or tripping `VM_BUG_ON(count != SWAP_HAS_CACHE)` in `__swap_entry_free_locked()`. Any of these panics the kernel."

Summary
In the Linux kernel, the following vulnerability has been resolved:
cachefiles: Set object to close if ondemand_id < 0 in copen
If copen is maliciously called in the user mode, it may delete the request
corresponding to the random id. And the request may have not been read yet.
Note that when the object is set to reopen, the open request will be done
with the still reopen state in above case. As a result, the request
corresponding to this object is always skipped in select_req function, so
the read request is never completed and blocks other process.
Fix this issue by simply set object to close if its id < 0 in copen.

nvmet-tcp: fix kernel crash if commands allocation fails
If the commands allocation fails in nvmet_tcp_alloc_cmds()
the kernel crashes in nvmet_tcp_release_queue_work() because of
a NULL pointer dereference.
nvmet: failed to install queue 0 cntlid 1 ret 6
Unable to handle kernel NULL pointer dereference at
virtual address 0000000000000008
Fix the bug by setting queue->nr_cmds to zero in case
nvmet_tcp_alloc_cmd() fails.

"value": "AV:N - The vulnerable code is `nvmet_tcp_install_queue()` in the NVMe-over-TCP target driver, reached directly from an NVMe Fabrics Connect capsule received on the target\u0027s listening TCP socket (default port 4420). A remote initiator anywhere on the network triggers it with ordinary NVMe/TCP protocol traffic.\nAC:L - The attacker deterministically forces the allocation failure by setting `sqsize` in the admin Connect command, which since commit 143667ee9a9c is unbounded for qid 0, making `kcalloc(131072, sizeof(struct nvmet_tcp_cmd))` exceed MAX_PAGE_ORDER and return NULL every time; on older branches the same is achieved with parallel max-size connections. No race, no memory-layout condition, and no state outside the attacker\u0027s control is involved.\nPR:N - `nvmet_install_queue()` runs inside the admin Connect handler before any DH-HMAC-CHAP authentication exchange, and `nvmet_host_allowed()` returns true unconditionally for the discovery subsystem exposed by every nvmet-tcp port. An entirely unauthenticated remote peer with TCP reachability can drive the path.\nUI:N - The crash is triggered purely by attacker-sent NVMe/TCP capsules followed by closing the connection. No action by any local user or administrator is required.\nS:U - The NULL dereference occurs in a kernel workqueue context and its impact is confined to the kernel on the target host, with no crossing into another security authority such as a hypervisor or IOMMU boundary.\nC:N - The fault is a read of `cmd-\u003ereq.cmd` at fixed address NULL+0x8 that oopses on the very first loop iteration; a remote TCP peer has no means to map the zero page, so no kernel data is read back or disclosed to the attacker.\nI:N - Execution stops at the faulting read before reaching the later `nvmet_tcp_free_cmd_buffers()` stores, and the dereferenced address is a fixed unmapped low address rather than attacker-controlled memory, so nothing is modified or corrupted.\nA:H - The result is a kernel NULL pointer dereference oops in the `nvmet_tcp_wq` kworker \u2014 a full panic on systems with `panic_on_oops` \u2014 repeatable at will by an unauthenticated remote attacker, and each attempt additionally leaks the queue allocation, socket file reference and IDA index."

Summary
In the Linux kernel, the following vulnerability has been resolved:
filelock: fix potential use-after-free in posix_lock_inode
Light Hsieh reported a KASAN UAF warning in trace_posix_lock_inode().
The request pointer had been changed earlier to point to a lock entry
that was added to the inode's list. However, before the tracepoint could
fire, another task raced in and freed that lock.
Fix this by moving the tracepoint inside the spinlock, which should
ensure that this doesn't happen.

Consistent with this CNA\u0027s scoring of other tracepoint-gated use-after-frees (CVE-2026-63910, CVE-2024-56759), the tracepoint-enabled precondition does not raise complexity.\nPR:L - Any unprivileged local user can call `fcntl()` on a file descriptor for a file it can already open; the only gate on the path is the `security_file_lock()` LSM hook, with no capability, root, or namespace requirement. POSIX advisory locks work on ordinary files in `/tmp`, `/dev/shm`, or the user\u0027s home directory.\nUI:N - The attacker\u0027s own threads perform every step \u2014 allocating the lock, merging it, and freeing it concurrently \u2014 with no action required from any other user or administrator.\nS:U - The freed `struct file_lock`, the corrupted read, and any resulting panic are all confined to the kernel of the same system; no VM, IOMMU, container, or sandbox boundary is crossed.\nC:H - The tracepoint reads seven fields out of a freed `filelock_cache` object \u2014 including the raw `flc_blocker` and `flc_owner` kernel pointers and the 64-bit `fl_start`/`fl_end` \u2014 after the attacker has had the opportunity to groom and reallocate that slab object, disclosing arbitrary reallocated kernel memory contents and defeating KASLR. Per kernel scoring guidance, use-after-free is rated High.\nI:H - A use-after-free on a `struct file_lock` that the attacker can reliably reallocate under control gives the classic UAF primitive \u2014 the stale `request` pointer is consumed as a live object after `kmem_cache_free()`, and heap spraying against the freed slot makes the condition exploitable for memory corruption rather than a benign stale read. Consistent with kernel guidance and this CNA\u0027s rating of the equivalent `dma_buf_fd()` tracepoint UAF, integrity impact is High.\nA:H - This is precisely the reported failure mode: the UAF read faulted the kernel on the reporter\u0027s MTE-enabled ARM64 system (`do_tag_check_fault` \u2192 `__do_kernel_fault` \u2192 panic), and on KASAN, hardware-tag, `slub_debug`, or `DEBUG_PAGEALLOC` builds the dereference of freed slab memory oopses. The race can be re-triggered in a loop, giving a repeatable local denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
fix bitmap corruption on close_range() with CLOSE_RANGE_UNSHARE
copy_fd_bitmaps(new, old, count) is expected to copy the first
count/BITS_PER_LONG bits from old->full_fds_bits[] and fill
the rest with zeroes. What it does is copying enough words
(BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest.
That works fine, *if* all bits past the cutoff point are
clear. Otherwise we are risking garbage from the last word
we'd copied.
For most of the callers that is true - expand_fdtable() has
count equal to old->max_fds, so there's no open descriptors
past count, let alone fully occupied words in ->open_fds[],
which is what bits in ->full_fds_bits[] correspond to.
The other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds),
which is the smallest multiple of BITS_PER_LONG that covers all
opened descriptors below max_fds. In the common case (copying on
fork()) max_fds is ~0U, so all opened descriptors will be below
it and we are fine, by the same reasons why the call in expand_fdtable()
is safe.
Unfortunately, there is a case where max_fds is less than that
and where we might, indeed, end up with junk in ->full_fds_bits[] -
close_range(from, to, CLOSE_RANGE_UNSHARE) with
* descriptor table being currently shared
* 'to' being above the current capacity of descriptor table
* 'from' being just under some chunk of opened descriptors.
In that case we end up with observably wrong behaviour - e.g. spawn
a child with CLONE_FILES, get all descriptors in range 0..127 open,
then close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending
up with descriptor #128, despite #64 being observably not open.
The minimally invasive fix would be to deal with that in dup_fd().
If this proves to add measurable overhead, we can go that way, but
let's try to fix copy_fd_bitmaps() first.
* new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).
* make copy_fd_bitmaps() take the bitmap size in words, rather than
bits; it's 'count' argument is always a multiple of BITS_PER_LONG,
so we are not losing any information, and that way we can use the
same helper for all three bitmaps - compiler will see that count
is a multiple of BITS_PER_LONG for the large ones, so it'll generate
plain memcpy()+memset().

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/dasd: fix error recovery leading to data corruption on ESE devices
Extent Space Efficient (ESE) or thin provisioned volumes need to be
formatted on demand during usual IO processing.
The dasd_ese_needs_format function checks for error codes that signal
the non existence of a proper track format.
The check for incorrect length is to imprecise since other error cases
leading to transport of insufficient data also have this flag set.
This might lead to data corruption in certain error cases for example
during a storage server warmstart.
Fix by removing the check for incorrect length and replacing by
explicitly checking for invalid track format in transport mode.
Also remove the check for file protected since this is not a valid
ESE handling case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: dapm: Fix UAF for snd_soc_pcm_runtime object
When using kernel with the following extra config,
- CONFIG_KASAN=y
- CONFIG_KASAN_GENERIC=y
- CONFIG_KASAN_INLINE=y
- CONFIG_KASAN_VMALLOC=y
- CONFIG_FRAME_WARN=4096
kernel detects that snd_pcm_suspend_all() access a freed
'snd_soc_pcm_runtime' object when the system is suspended, which
leads to a use-after-free bug:
[ 52.047746] BUG: KASAN: use-after-free in snd_pcm_suspend_all+0x1a8/0x270
[ 52.047765] Read of size 1 at addr ffff0000b9434d50 by task systemd-sleep/2330
[ 52.047785] Call trace:
[ 52.047787] dump_backtrace+0x0/0x3c0
[ 52.047794] show_stack+0x34/0x50
[ 52.047797] dump_stack_lvl+0x68/0x8c
[ 52.047802] print_address_description.constprop.0+0x74/0x2c0
[ 52.047809] kasan_report+0x210/0x230
[ 52.047815] __asan_report_load1_noabort+0x3c/0x50
[ 52.047820] snd_pcm_suspend_all+0x1a8/0x270
[ 52.047824] snd_soc_suspend+0x19c/0x4e0
The snd_pcm_sync_stop() has a NULL check on 'substream->runtime' before
making any access. So we need to always set 'substream->runtime' to NULL
everytime we kfree() it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: check validation of fault attrs in f2fs_build_fault_attr()
- It missed to check validation of fault attrs in parse_options(),
let's fix to add check condition in f2fs_build_fault_attr().
- Use f2fs_build_fault_attr() in __sbi_store() to clean up code.

"value": "AV:A - The teardown path is reached via `ndo_tx_timeout`, which `dev_watchdog()` fires when the TX queue stays stopped for 10 s with carrier up \u2014 inducible by an attacker on the same Ethernet segment via sustained 802.3x PAUSE flooding or link-level stalling of the 100 Mbit MAC on these Lantiq CPE devices. The stall mechanism is link-local L2 and does not survive a router hop, so Adjacent rather than Network.\nAC:L - The attacker fully controls the stalling condition and can simply keep transmitting PAUSE frames past the 10-second watchdog window, and the buggy loop then unconditionally frees the same skb 192 times with no race or layout precondition. Heap grooming of the freed skb is also attacker-controlled since the same interface is receiving their traffic.\nPR:N - No account, credential, or authentication on the target is needed \u2014 an unauthenticated peer on the link segment only has to emit flow-control/traffic frames to trip the transmit watchdog. No local access or capability is involved on this path.\nUI:N - The watchdog timer fires automatically from `dev_watchdog()` and calls `ltq_etop_tx_timeout()` with no administrator or user action. No interface down/up, unbind, or module unload by a legitimate user is required.\nS:U - The double free corrupts kernel slab state within the same kernel security authority; no VM, hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The 191 redundant frees operate on freed sk_buff memory, dereferencing `skb-\u003ehead`/`skb-\u003eend` to reach `skb_shinfo()` and re-inserting the object into the skb slab freelist, producing overlapping allocations that let an attacker read reallocated kernel heap contents (other packets, credentials, kernel pointers). Per kernel guidance, use-after-free/double-free is scored High confidentiality.\nI:H - Freeing the same object 192 times corrupts the `skbuff_cache` freelist into aliased allocations (arbitrary write primitive) and drives an indirect call through the attacker-influenceable `skb-\u003edestructor` field in `skb_release_head_state()`, plus a controlled `skb-\u003ehead` free and page refcount decrements. This is a control-flow-hijack-capable memory corruption, not a bounded modification.\nA:H - Even without exploitation the 191-fold double free reliably triggers slab corruption, list poisoning, and kernel panic/oops, and the DMA engine may still have the freed buffer mapped. The trigger is repeatable at will by the adjacent attacker."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Using uninitialized value *size when calling amdgpu_vce_cs_reloc
Initialize the size before calling amdgpu_vce_cs_reloc, such as case 0x03000001.
V2: To really improve the handling we would actually
need to have a separate value of 0xffffffff.(Christian)

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix kernel bug on rename operation of broken directory
Syzbot reported that in rename directory operation on broken directory on
nilfs2, __block_write_begin_int() called to prepare block write may fail
BUG_ON check for access exceeding the folio/page size.
This is because nilfs_dotdot(), which gets parent directory reference
entry ("..") of the directory to be moved or renamed, does not check
consistency enough, and may return location exceeding folio/page size for
broken directories.
Fix this issue by checking required directory entries ("." and "..") in
the first chunk of the directory in nilfs_dotdot().

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: add missing check for inode numbers on directory entries
Syzbot reported that mounting and unmounting a specific pattern of
corrupted nilfs2 filesystem images causes a use-after-free of metadata
file inodes, which triggers a kernel bug in lru_add_fn().
As Jan Kara pointed out, this is because the link count of a metadata file
gets corrupted to 0, and nilfs_evict_inode(), which is called from iput(),
tries to delete that inode (ifile inode in this case).
The inconsistency occurs because directories containing the inode numbers
of these metadata files that should not be visible in the namespace are
read without checking.
Fix this issue by treating the inode numbers of these internal files as
errors in the sanity check helper when reading directory folios/pages.
Also thanks to Hillf Danton and Matthew Wilcox for their initial mm-layer
analysis.

Reachable via local syscalls on media the attacker supplies, e.g. a USB device auto-mounted by udisks2 on a desktop or kiosk.\nAC:L - The attacker fully controls the on-disk directory block, so simply placing a metadata inode number (e.g. ifile=6) in a directory entry makes `nilfs_check_folio()` accept it and `nilfs_iget()` return the live metadata inode deterministically. No race and no uncontrolled precondition is involved.\nPR:L - The attacker needs local unprivileged access to attach the malicious image (removable media auto-mounted by udisks2/systemd for the console user, or any environment granting the user mount of removable/loop devices) and then only needs ordinary file operations on the mount to trigger the metadata-inode eviction.\nUI:N - In the automount scenario the attacker performs every step themselves \u2014 inserting the media and running `ls`/`rm` on the resulting mount \u2014 so no separate victim action is required.\nS:U - The corruption stays within the kernel\u0027s own security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The freed metadata inode (and its page cache/palloc cache) continues to be dereferenced by the filesystem, and a use-after-free of a slab-allocated `struct inode` gives an attacker who reclaims the object a path to disclose kernel memory; the ifile inode also exposes raw filesystem metadata through the namespace.\nI:H - `nilfs_evict_inode()` truncates and deletes the filesystem\u0027s own ifile inode while it is still in use, and the resulting use-after-free of the inode object allows heap-spray reclaim of attacker-controlled data into a structure the kernel then writes through \u2014 a write/control-flow primitive, not just metadata damage.\nA:H - Syzbot reproduced a kernel BUG in `lru_add_fn()` from this use-after-free on mount/unmount; any local user able to mount the crafted image can panic the machine reliably."

Summary
In the Linux kernel, the following vulnerability has been resolved:
leds: mlxreg: Use devm_mutex_init() for mutex initialization
In this driver LEDs are registered using devm_led_classdev_register()
so they are automatically unregistered after module's remove() is done.
led_classdev_unregister() calls module's led_set_brightness() to turn off
the LEDs and that callback uses mutex which was destroyed already
in module's remove() so use devm API instead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: Intel: hda: fix null deref on system suspend entry
When system enters suspend with an active stream, SOF core
calls hw_params_upon_resume(). On Intel platforms with HDA DMA used
to manage the link DMA, this leads to call chain of
hda_dsp_set_hw_params_upon_resume()
-> hda_dsp_dais_suspend()
-> hda_dai_suspend()
-> hda_ipc4_post_trigger()
A bug is hit in hda_dai_suspend() as hda_link_dma_cleanup() is run first,
which clears hext_stream->link_substream, and then hda_ipc4_post_trigger()
is called with a NULL snd_pcm_substream pointer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cachefiles: cyclic allocation of msg_id to avoid reuse
Reusing the msg_id after a maliciously completed reopen request may cause
a read request to remain unprocessed and result in a hung, as shown below:
t1 | t2 | t3
-------------------------------------------------
cachefiles_ondemand_select_req
cachefiles_ondemand_object_is_close(A)
cachefiles_ondemand_set_object_reopening(A)
queue_work(fscache_object_wq, &info->work)
ondemand_object_worker
cachefiles_ondemand_init_object(A)
cachefiles_ondemand_send_req(OPEN)
// get msg_id 6
wait_for_completion(&req_A->done)
cachefiles_ondemand_daemon_read
// read msg_id 6 req_A
cachefiles_ondemand_get_fd
copy_to_user
// Malicious completion msg_id 6
copen 6,-1
cachefiles_ondemand_copen
complete(&req_A->done)
// will not set the object to close
// because ondemand_id && fd is valid.
// ondemand_object_worker() is done
// but the object is still reopening.
// new open req_B
cachefiles_ondemand_init_object(B)
cachefiles_ondemand_send_req(OPEN)
// reuse msg_id 6
process_open_req
copen 6,A.size
// The expected failed copen was executed successfully
Expect copen to fail, and when it does, it closes fd, which sets the
object to close, and then close triggers reopen again. However, due to
msg_id reuse resulting in a successful copen, the anonymous fd is not
closed until the daemon exits. Therefore read requests waiting for reopen
to complete may trigger hung task.
To avoid this issue, allocate the msg_id cyclically to avoid reusing the
msg_id for a very short duration of time.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bluetooth/hci: disallow setting handle bigger than HCI_CONN_HANDLE_MAX
Syzbot hit warning in hci_conn_del() caused by freeing handle that was
not allocated using ida allocator.
This is caused by handle bigger than HCI_CONN_HANDLE_MAX passed by
hci_le_big_sync_established_evt(), which makes code think it's unset
connection.
Add same check for handle upper bound as in hci_conn_set_handle() to
prevent warning.

This is bounded kernel-state modification, not an arbitrary write.\nA:H - The bug reliably triggers a kernel WARNING, which is a panic on the many deployments (Android, CI, hardened distros) running with `panic_on_warn`, and the resulting duplicate-handle confusion persistently disrupts Bluetooth connection handling."

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/restrack: Fix potential invalid address access
struct rdma_restrack_entry's kern_name was set to KBUILD_MODNAME
in ib_create_cq(), while if the module exited but forgot del this
rdma_restrack_entry, it would cause a invalid address access in
rdma_restrack_clean() when print the owner of this rdma_restrack_entry.
These code is used to help find one forgotten PD release in one of the
ULPs. But it is not needed anymore, so delete them.

The command completion was done early while aborting the commands in driver
unload path but outside lock to avoid the WARN_ON condition of performing
dma_free_attr within the lock. However this caused race condition while
command completion via multiple paths causing system crash.
Hence complete the command early in unload path but within the lock to
avoid race condition.

No memory layout or victim state outside the attacker\u0027s influence is required.\nPR:N - Fibre Channel has no authentication in practice (zoning only, FC-SP rarely deployed), so a peer on the fabric needs no credentials on the target host; in target mode the initiator drives the outstanding commands pre-authentication.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tun: add missing verification for short frame
The cited commit missed to check against the validity of the frame length
in the tun_xdp_one() path, which could cause a corrupted skb to be sent
downstack. Even before the skb is transmitted, the
tun_xdp_one-->eth_type_trans() may access the Ethernet header although it
can be less than ETH_HLEN. Once transmitted, this could either cause
out-of-bound access beyond the actual length, or confuse the underlayer
with incorrect or inconsistent header length in the skb metadata.
In the alternative path, tun_get_user() already prohibits short frame which
has the length less than Ethernet header size from being transmitted for
IFF_TAP.
This is to drop any frame shorter than the Ethernet header size just like
how tun_get_user() does.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Defer work in bpf_timer_cancel_and_free
Currently, the same case as previous patch (two timer callbacks trying
to cancel each other) can be invoked through bpf_map_update_elem as
well, or more precisely, freeing map elements containing timers. Since
this relies on hrtimer_cancel as well, it is prone to the same deadlock
situation as the previous patch.
It would be sufficient to use hrtimer_try_to_cancel to fix this problem,
as the timer cannot be enqueued after async_cancel_and_free. Once
async_cancel_and_free has been done, the timer must be reinitialized
before it can be armed again. The callback running in parallel trying to
arm the timer will fail, and freeing bpf_hrtimer without waiting is
sufficient (given kfree_rcu), and bpf_timer_cb will return
HRTIMER_NORESTART, preventing the timer from being rearmed again.
However, there exists a UAF scenario where the callback arms the timer
before entering this function, such that if cancellation fails (due to
timer callback invoking this routine, or the target timer callback
running concurrently). In such a case, if the timer expiration is
significantly far in the future, the RCU grace period expiration
happening before it will free the bpf_hrtimer state and along with it
the struct hrtimer, that is enqueued.
Hence, it is clear cancellation needs to occur after
async_cancel_and_free, and yet it cannot be done inline due to deadlock
issues. We thus modify bpf_timer_cancel_and_free to defer work to the
global workqueue, adding a work_struct alongside rcu_head (both used at
_different_ points of time, so can share space).
Update existing code comments to reflect the new state of affairs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: Add missing bridge lock to pci_bus_lock()
One of the true positives that the cfg_access_lock lockdep effort
identified is this sequence:
WARNING: CPU: 14 PID: 1 at drivers/pci/pci.c:4886 pci_bridge_secondary_bus_reset+0x5d/0x70
RIP: 0010:pci_bridge_secondary_bus_reset+0x5d/0x70

Where pci_reset_bus() users are triggering unlocked secondary bus resets.
Ironically pci_bus_reset(), several calls down from pci_reset_bus(), uses
pci_bus_lock() before issuing the reset which locks everything *but* the
bridge itself.
For the same motivation as adding:
bridge = pci_upstream_bridge(dev);
if (bridge)
pci_dev_lock(bridge);
to pci_reset_function() for the "bus" and "cxl_bus" reset cases, add
pci_dev_lock() for @bus->self to pci_bus_lock().

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_acl_erp: Fix object nesting warning
ACLs in Spectrum-2 and newer ASICs can reside in the algorithmic TCAM
(A-TCAM) or in the ordinary circuit TCAM (C-TCAM). The former can
contain more ACLs (i.e., tc filters), but the number of masks in each
region (i.e., tc chain) is limited.
In order to mitigate the effects of the above limitation, the device
allows filters to share a single mask if their masks only differ in up
to 8 consecutive bits. For example, dst_ip/25 can be represented using
dst_ip/24 with a delta of 1 bit. The C-TCAM does not have a limit on the
number of masks being used (and therefore does not support mask
aggregation), but can contain a limited number of filters.
The driver uses the "objagg" library to perform the mask aggregation by
passing it objects that consist of the filter's mask and whether the
filter is to be inserted into the A-TCAM or the C-TCAM since filters in
different TCAMs cannot share a mask.
The set of created objects is dependent on the insertion order of the
filters and is not necessarily optimal. Therefore, the driver will
periodically ask the library to compute a more optimal set ("hints") by
looking at all the existing objects.
When the library asks the driver whether two objects can be aggregated
the driver only compares the provided masks and ignores the A-TCAM /
C-TCAM indication. This is the right thing to do since the goal is to
move as many filters as possible to the A-TCAM. The driver also forbids
two identical masks from being aggregated since this can only happen if
one was intentionally put in the C-TCAM to avoid a conflict in the
A-TCAM.
The above can result in the following set of hints:
H1: {mask X, A-TCAM} -> H2: {mask Y, A-TCAM} // X is Y + delta
H3: {mask Y, C-TCAM} -> H4: {mask Z, A-TCAM} // Y is Z + delta
After getting the hints from the library the driver will start migrating
filters from one region to another while consulting the computed hints
and instructing the device to perform a lookup in both regions during
the transition.
Assuming a filter with mask X is being migrated into the A-TCAM in the
new region, the hints lookup will return H1. Since H2 is the parent of
H1, the library will try to find the object associated with it and
create it if necessary in which case another hints lookup (recursive)
will be performed. This hints lookup for {mask Y, A-TCAM} will either
return H2 or H3 since the driver passes the library an object comparison
function that ignores the A-TCAM / C-TCAM indication.
This can eventually lead to nested objects which are not supported by
the library [1].
Fix by removing the object comparison function from both the driver and
the library as the driver was the only user. That way the lookup will
only return exact matches.
I do not have a reliable reproducer that can reproduce the issue in a
timely manner, but before the fix the issue would reproduce in several
minutes and with the fix it does not reproduce in over an hour.
Note that the current usefulness of the hints is limited because they
include the C-TCAM indication and represent aggregation that cannot
actually happen. This will be addressed in net-next.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmlxsw: spectrum_acl_erp: Fix object nesting warning\n\nACLs in Spectrum-2 and newer ASICs can reside in the algorithmic TCAM\n(A-TCAM) or in the ordinary circuit TCAM (C-TCAM). The former can\ncontain more ACLs (i.e., tc filters), but the number of masks in each\nregion (i.e., tc chain) is limited.\n\nIn order to mitigate the effects of the above limitation, the device\nallows filters to share a single mask if their masks only differ in up\nto 8 consecutive bits. For example, dst_ip/25 can be represented using\ndst_ip/24 with a delta of 1 bit. The C-TCAM does not have a limit on the\nnumber of masks being used (and therefore does not support mask\naggregation), but can contain a limited number of filters.\n\nThe driver uses the \"objagg\" library to perform the mask aggregation by\npassing it objects that consist of the filter\u0027s mask and whether the\nfilter is to be inserted into the A-TCAM or the C-TCAM since filters in\ndifferent TCAMs cannot share a mask.\n\nThe set of created objects is dependent on the insertion order of the\nfilters and is not necessarily optimal. Therefore, the driver will\nperiodically ask the library to compute a more optimal set (\"hints\") by\nlooking at all the existing objects.\n\nWhen the library asks the driver whether two objects can be aggregated\nthe driver only compares the provided masks and ignores the A-TCAM /\nC-TCAM indication. This is the right thing to do since the goal is to\nmove as many filters as possible to the A-TCAM. The driver also forbids\ntwo identical masks from being aggregated since this can only happen if\none was intentionally put in the C-TCAM to avoid a conflict in the\nA-TCAM.\n\nThe above can result in the following set of hints:\n\nH1: {mask X, A-TCAM} -\u003e H2: {mask Y, A-TCAM} // X is Y + delta\nH3: {mask Y, C-TCAM} -\u003e H4: {mask Z, A-TCAM} // Y is Z + delta\n\nAfter getting the hints from the library the driver will start migrating\nfilters from one region to another while consulting the computed hints\nand instructing the device to perform a lookup in both regions during\nthe transition.\n\nAssuming a filter with mask X is being migrated into the A-TCAM in the\nnew region, the hints lookup will return H1. Since H2 is the parent of\nH1, the library will try to find the object associated with it and\ncreate it if necessary in which case another hints lookup (recursive)\nwill be performed. This hints lookup for {mask Y, A-TCAM} will either\nreturn H2 or H3 since the driver passes the library an object comparison\nfunction that ignores the A-TCAM / C-TCAM indication.\n\nThis can eventually lead to nested objects which are not supported by\nthe library [1].\n\nFix by removing the object comparison function from both the driver and\nthe library as the driver was the only user. That way the lookup will\nonly return exact matches.\n\nI do not have a reliable reproducer that can reproduce the issue in a\ntimely manner, but before the fix the issue would reproduce in several\nminutes and with the fix it does not reproduce in over an hour.\n\nNote that the current usefulness of the hints is limited because they\ninclude the C-TCAM indication and represent aggregation that cannot\nactually happen. This will be addressed in net-next.\n\n[1]\nWARNING: CPU: 0 PID: 153 at lib/objagg.c:170 objagg_obj_parent_assign+0xb5/0xd0\nModules linked in:\nCPU: 0 PID: 153 Comm: kworker/0:18 Not tainted 6.9.0-rc6-custom-g70fbc2c1c38b #42\nHardware name: Mellanox Technologies Ltd.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/client: fix null pointer dereference in drm_client_modeset_probe
In drm_client_modeset_probe(), the return value of drm_mode_duplicate() is
assigned to modeset->mode, which will lead to a possible NULL pointer
dereference on failure of drm_mode_duplicate(). Add a check to avoid npd.

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: core: Fix duplicate endpoint bug by clearing reserved bits in the descriptor
Syzbot has identified a bug in usbcore (see the Closes: tag below)
caused by our assumption that the reserved bits in an endpoint
descriptor's bEndpointAddress field will always be 0. As a result of
the bug, the endpoint_is_duplicate() routine in config.c (and possibly
other routines as well) may believe that two descriptors are for
distinct endpoints, even though they have the same direction and
endpoint number. This can lead to confusion, including the bug
identified by syzbot (two descriptors with matching endpoint numbers
and directions, where one was interrupt and the other was bulk).
To fix the bug, we will clear the reserved bits in bEndpointAddress
when we parse the descriptor. (Note that both the USB-2.0 and USB-3.1
specs say these bits are "Reserved, reset to zero".) This requires us
to make a copy of the descriptor earlier in usb_parse_endpoint() and
use the copy instead of the original when checking for duplicates.

This can lead to confusion, including the bug\nidentified by syzbot (two descriptors with matching endpoint numbers\nand directions, where one was interrupt and the other was bulk).\n\nTo fix the bug, we will clear the reserved bits in bEndpointAddress\nwhen we parse the descriptor. (Note that both the USB-2.0 and USB-3.1\nspecs say these bits are \"Reserved, reset to zero\".) This requires us\nto make a copy of the descriptor earlier in usb_parse_endpoint() and\nuse the copy instead of the original when checking for duplicates."

Summary
In the Linux kernel, the following vulnerability has been resolved:
jffs2: Fix potential illegal address access in jffs2_free_inode
During the stress testing of the jffs2 file system,the following
abnormal printouts were found:

The parameter passed to kfree was 5a5a5a5a, which corresponds to the target field of
the jffs_inode_info structure. It was found that all variables in the jffs_inode_info
structure were 5a5a5a5a, except for the first member sem. It is suspected that these
variables are not initialized because they were set to 5a5a5a5a during memory testing,
which is meant to detect uninitialized memory.The sem variable is initialized in the
function jffs2_i_init_once, while other members are initialized in
the function jffs2_init_inode_info.
The function jffs2_init_inode_info is called after iget_locked,
but in the iget_locked function, the destroy_inode process is triggered,
which releases the inode and consequently, the target member of the inode
is not initialized.In concurrent high pressure scenarios, iget_locked
may enter the destroy_inode branch as described in the code.
Since the destroy_inode functionality of jffs2 only releases the target,
the fix method is to set target to NULL in jffs2_i_init_once.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: avoid overflows in dirty throttling logic
The dirty throttling logic is interspersed with assumptions that dirty
limits in PAGE_SIZE units fit into 32-bit (so that various multiplications
fit into 64-bits). If limits end up being larger, we will hit overflows,
possible divisions by 0 etc. Fix these problems by never allowing so
large dirty limits as they have dubious practical value anyway. For
dirty_bytes / dirty_background_bytes interfaces we can just refuse to set
so large limits. For dirty_ratio / dirty_background_ratio it isn't so
simple as the dirty limit is computed from the amount of available memory
which can change due to memory hotplug etc. So when converting dirty
limits from ratios to numbers of pages, we just don't allow the result to
exceed UINT_MAX.
This is root-only triggerable problem which occurs when the operator
sets dirty limits to >16 TB.

For\ndirty_bytes / dirty_background_bytes interfaces we can just refuse to set\nso large limits. For dirty_ratio / dirty_background_ratio it isn\u0027t so\nsimple as the dirty limit is computed from the amount of available memory\nwhich can change due to memory hotplug etc. So when converting dirty\nlimits from ratios to numbers of pages, we just don\u0027t allow the result to\nexceed UINT_MAX.\n\nThis is root-only triggerable problem which occurs when the operator\nsets dirty limits to \u003e16 TB."

Summary
In the Linux kernel, the following vulnerability has been resolved:
inet_diag: Initialize pad field in struct inet_diag_req_v2
KMSAN reported uninit-value access in raw_lookup() [1]. Diag for raw
sockets uses the pad field in struct inet_diag_req_v2 for the
underlying protocol. This field corresponds to the sdiag_raw_protocol
field in struct inet_diag_req_raw.
inet_diag_get_exact_compat() converts inet_diag_req to
inet_diag_req_v2, but leaves the pad field uninitialized. So the issue
occurs when raw_lookup() accesses the sdiag_raw_protocol field.
Fix this by initializing the pad field in
inet_diag_get_exact_compat(). Also, do the same fix in
inet_diag_dump_compat() to avoid the similar issue in the future.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: prefer nft_chain_validate
nft_chain_validate already performs loop detection because a cycle will
result in a call stack overflow (ctx->level >= NFT_JUMP_STACK_SIZE).
It also follows maps via ->validate callback in nft_lookup, so there
appears no reason to iterate the maps again.
nf_tables_check_loops() and all its helper functions can be removed.
This improves ruleset load time significantly, from 23s down to 12s.
This also fixes a crash bug. Old loop detection code can result in
unbounded recursion:
BUG: TASK stack guard page was hit at ....
Oops: stack guard page: 0000 [#1] PREEMPT SMP KASAN
CPU: 4 PID: 1539 Comm: nft Not tainted 6.10.0-rc5+ #1
[..]
with a suitable ruleset during validation of register stores.
I can't see any actual reason to attempt to check for this from
nft_validate_register_store(), at this point the transaction is still in
progress, so we don't have a full picture of the rule graph.
For nf-next it might make sense to either remove it or make this depend
on table->validate_state in case we could catch an error earlier
(for improved error reporting to userspace).

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix overflow in get_free_elt()
"tracing_map->next_elt" in get_free_elt() is at risk of overflowing.
Once it overflows, new elements can still be inserted into the tracing_map
even though the maximum number of elements (`max_elts`) has been reached.
Continuing to insert elements after the overflow could result in the
tracing_map containing "tracing_map->max_size" elements, leaving no empty
entries.
If any attempt is made to insert an element into a full tracing_map using
`__tracing_map_insert()`, it will cause an infinite loop with preemption
disabled, leading to a CPU hang problem.
Fix this by preventing any further increments to "tracing_map->next_elt"
once it reaches "tracing_map->max_elt".

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/iucv: fix use after free in iucv_sock_close()
iucv_sever_path() is called from process context and from bh context.
iucv->path is used as indicator whether somebody else is taking care of
severing the path (or it is already removed / never existed).
This needs to be done with atomic compare and swap, otherwise there is a
small window where iucv_sock_close() will try to work with a path that has
already been severed and freed by iucv_callback_connrej() called by
iucv_tasklet_fn().
Example:
[452744.123844] Call Trace:

[452744.125325] Kernel panic - not syncing: Fatal exception in interrupt
Note that bh_lock_sock() is not serializing the tasklet context against
process context, because the check for sock_owned_by_user() and
corresponding handling is missing.
Ideas for a future clean-up patch:
A) Correct usage of bh_lock_sock() in tasklet context, as described in
Re-enqueue, if needed. This may require adding return values to the
tasklet functions and thus changes to all users of iucv.
B) Change iucv tasklet into worker and use only lock_sock() in af_iucv.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/iwcm: Fix a use-after-free related to destroying CM IDs
iw_conn_req_handler() associates a new struct rdma_id_private (conn_id) with
an existing struct iw_cm_id (cm_id) as follows:
conn_id->cm_id.iw = cm_id;
cm_id->context = conn_id;
cm_id->cm_handler = cma_iw_handler;
rdma_destroy_id() frees both the cm_id and the struct rdma_id_private. Make
sure that cm_work_handler() does not trigger a use-after-free by only
freeing of the struct rdma_id_private after all pending work has finished.

Network-facing RDMA targets over iWARP (nvmet-rdma, NFS/RDMA svcrdma, iSER, SMB Direct, on cxgb4/irdma/qedr or software siw) drive both the event delivery and the `rdma_destroy_id()` teardown from remote peer actions.\nAC:L - The attacker controls both sides of the race: the connect/abort lifecycle of their own connection generates the queued CM events, and forcing a connection rejection or resetting the TCP connection drives the concurrent `rdma_destroy_id()`. The sequence can be repeated in a tight loop across many concurrent connections until the window is hit, with no condition outside attacker influence.\nPR:N - The RDMA-CM/iWARP handshake and the entire connect-reject-disconnect cycle complete before any upper-layer authentication (NVMe-oF Connect/in-band auth, RPCSEC, SMB session setup), so an unauthenticated peer that can reach the target port suffices. The local variant is even weaker-gated: rdma_ucm\u0027s `/dev/infiniband/rdma_cm` handlers contain no capability checks at all.\nUI:N - Exploitation is entirely driven by the attacker\u0027s own connection attempts and teardowns against an already-listening RDMA service. No action by any local user or administrator is required.\nS:U - The use-after-free corrupts kernel heap memory and hijacks kernel control flow within the same security authority as the vulnerable component. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - After the free, `cma_iw_handler()` reads `id_priv-\u003estate`, `id_priv-\u003ecm_id`, and other fields from the reallocated slab object, and the resulting control-flow hijack via the stale `event_handler` pointer can be leveraged for arbitrary kernel memory disclosure. Per kernel guidance a use-after-free is scored High for confidentiality.\nI:H - `cma_cm_event_handler()` performs an indirect call through `id_priv-\u003eid.event_handler` read from the freed object, and `mutex_lock(\u0026id_priv-\u003ehandler_mutex)` writes into it \u2014 together giving heap-spray-based arbitrary write and code-execution potential. This is a full control-flow hijack primitive, not a bounded corruption.\nA:H - Even without successful grooming, dereferencing the freed `rdma_id_private` (mutex operations and an indirect call on garbage) reliably oopses or panics the kernel, as observed by KASAN slab-use-after-free reports during blktests. The trigger is repeatable, so a remote attacker can crash the target at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
soc: qcom: cmd-db: Map shared memory as WC, not WB
Linux does not write into cmd-db region. This region of memory is write
protected by XPU. XPU may sometime falsely detect clean cache eviction
as "write" into the write protected region leading to secure interrupt
which causes an endless loop somewhere in Trust Zone.
The only reason it is working right now is because Qualcomm Hypervisor
maps the same region as Non-Cacheable memory in Stage 2 translation
tables. The issue manifests if we want to use another hypervisor (like
Xen or KVM), which does not know anything about those specific mappings.
Changing the mapping of cmd-db memory from MEMREMAP_WB to MEMREMAP_WT/WC
removes dependency on correct mappings in Stage 2 tables. This patch
fixes the issue by updating the mapping to MEMREMAP_WC.
I tested this on SA8155P with Xen.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvmem: core: limit cell sysfs permissions to main attribute ones
The cell sysfs attribute should not provide more access to the nvmem
data than the main attribute itself.
For example if nvme_config::root_only was set, the cell attribute
would still provide read access to everybody.
Mask out permissions not available on the main attribute.

Summary
In the Linux kernel, the following vulnerability has been resolved:
kcm: Serialise kcm_sendmsg() for the same socket.
syzkaller reported UAF in kcm_release(). [0]
The scenario is
1. Thread A builds a skb with MSG_MORE and sets kcm->seq_skb.
2. Thread A resumes building skb from kcm->seq_skb but is blocked
by sk_stream_wait_memory()
3. Thread B calls sendmsg() concurrently, finishes building kcm->seq_skb
and puts the skb to the write queue
4. Thread A faces an error and finally frees skb that is already in the
write queue
5. kcm_release() does double-free the skb in the write queue
When a thread is building a MSG_MORE skb, another thread must not touch it.
Let's add a per-sk mutex and serialise kcm_sendmsg().

Local code execution on the system is required.\nAC:L - The attacker controls both sides of the race (two threads on one fd it owns) and controls the blocking window itself by shrinking `SO_SNDBUF` so `sk_stream_wait_memory()` reliably blocks with the sock lock dropped; syzbot reproduced it and confirmed the fix.\nPR:L - `kcm_create()` performs no `capable()`/`ns_capable()` check and `__sock_create()` autoloads `net-pf-41` without a capability gate, so any unprivileged local user can open a PF_KCM socket; no psock attach or CAP_NET_ADMIN is needed since the corrupted skb is purged at `kcm_release()`.\nUI:N - The attacker\u0027s own two threads perform every step \u2014 create the socket, race the sendmsg calls, and close the fd. No victim action is involved.\nS:U - The use-after-free and double free are confined to kernel heap within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - A freed `skbuff_head_cache` object stays linked in `sk_write_queue`, so its reclaimed contents are read back and, with an attached psock, `kcm_write_msgs()` can transmit the freed skb\u0027s frags to the peer \u2014 leaking kernel heap; a UAF of this shape is a general arbitrary-read primitive.\nI:H - `__skb_unlink()` on the freed skb writes through attacker-reclaimable `next`/`prev` pointers (`next-\u003eprev = prev; prev-\u003enext = next`), yielding a write-what-where primitive, compounded by a genuine double free of the skb \u2014 both are exploitable for control-flow hijack and privilege escalation.\nA:H - The reported KASAN slab-use-after-free in `kcm_release()` plus the double free corrupt the skb list and slab freelist, causing kernel oops/panic; any unprivileged user can trigger this repeatedly."

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: mediatek: vcodec: Only free buffer VA that is not NULL
In the MediaTek vcodec driver, while mtk_vcodec_mem_free() is mostly
called only when the buffer to free exists, there are some instances
that didn't do the check and triggered warnings in practice.
We believe those checks were forgotten unintentionally. Add the checks
back to fix the warnings.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: restrict NL80211_ATTR_TXQ_QUANTUM values
syzbot is able to trigger softlockups, setting NL80211_ATTR_TXQ_QUANTUM
to 2^31.
We had a similar issue in sch_fq, fixed with commit
d9e15a273306 ("pkt_sched: fq: do not accept silly TCA_FQ_QUANTUM")
watchdog: BUG: soft lockup - CPU#1 stuck for 26s! [kworker/1:0:24]

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: make sure the first directory block is not a hole
The syzbot constructs a directory that has no dirblock but is non-inline,
i.e. the first directory block is a hole. And no errors are reported when
creating files in this directory in the following flow.
ext4_mknod
...
ext4_add_entry
// Read block 0
ext4_read_dirblock(dir, block, DIRENT)
bh = ext4_bread(NULL, inode, block, 0)
if (!bh && (type == INDEX || type == DIRENT_HTREE))
// The first directory block is a hole
// But type == DIRENT, so no error is reported.
After that, we get a directory block without '.' and '..' but with a valid
dentry. This may cause some code that relies on dot or dotdot (such as
make_indexed_dir()) to crash.
Therefore when ext4_read_dirblock() finds that the first directory block
is a hole report that the filesystem is corrupted and return an error to
avoid loading corrupted data from disk causing something bad.

Summary
In the Linux kernel, the following vulnerability has been resolved:
inet: inet_defrag: prevent sk release while still in use
ip_local_out() and other functions can pass skb->sk as function argument.
If the skb is a fragment and reassembly happens before such function call
returns, the sk must not be released.
This affects skb fragments reassembled via netfilter or similar
modules, e.g. openvswitch or ct_act.c, when run as part of tx pipeline.
Eric Dumazet made an initial analysis of this bug. Quoting Eric:
Calling ip_defrag() in output path is also implying skb_orphan(),
which is buggy because output path relies on sk not disappearing.
A relevant old patch about the issue was :
8282f27449bf ("inet: frag: Always orphan skbs inside ip_defrag()")
[..]
net/ipv4/ip_output.c depends on skb->sk being set, and probably to an
inet socket, not an arbitrary one.
If we orphan the packet in ipvlan, then downstream things like FQ
packet scheduler will not work properly.
We need to change ip_defrag() to only use skb_orphan() when really
needed, ie whenever frag_list is going to be used.
Eric suggested to stash sk in fragment queue and made an initial patch.
However there is a problem with this:
If skb is refragmented again right after, ip_do_fragment() will copy
head->sk to the new fragments, and sets up destructor to sock_wfree.
IOW, we have no choice but to fix up sk_wmem accouting to reflect the
fully reassembled skb, else wmem will underflow.
This change moves the orphan down into the core, to last possible moment.
As ip_defrag_offset is aliased with sk_buff->sk member, we must move the
offset into the FRAG_CB, else skb->sk gets clobbered.
This allows to delay the orphaning long enough to learn if the skb has
to be queued or if the skb is completing the reasm queue.
In the former case, things work as before, skb is orphaned. This is
safe because skb gets queued/stolen and won't continue past reasm engine.
In the latter case, we will steal the skb->sk reference, reattach it to
the head skb, and fix up wmem accouting when inet_frag inflates truesize.

This is\nsafe because skb gets queued/stolen and won\u0027t continue past reasm engine.\n\nIn the latter case, we will steal the skb-\u003esk reference, reattach it to\nthe head skb, and fix up wmem accouting when inet_frag inflates truesize."

The free and the subsequent dereference occur deterministically in the same call stack, so no uncontrolled race must be won.\nPR:L - An unprivileged local user obtains CAP_NET_ADMIN and CAP_NET_RAW inside a user namespace (`unshare -Urn`), which is sufficient to create the ipvlan/veth devices, install an nftables/conntrack rule that registers the NF_INET_LOCAL_OUT defrag hook, and open a raw socket to inject IP fragments. No real root in the init namespace is required.\nUI:N - The attacker triggers the entire sequence from their own process with no action by any other user or administrator.\nS:U - The use-after-free corrupts kernel memory within the same security authority; there is no VM, IOMMU, or hypervisor boundary crossed.\nC:H - This is a use-after-free on `struct sock`; the confirmed KASAN splat is a slab-use-after-free *read* in `sk_fullsock()`/`ip_skb_dst_mtu()`, and reallocating the freed slab object under attacker-controlled data yields a general kernel-memory disclosure primitive.\nI:H - The stale `sk` is written to as well \u2014 `nf_queue_entry_get_refs()` does `sock_hold(state-\u003esk)` (refcount increment into freed memory) from the POST_ROUTING hook, and the freed `struct sock` is full of function pointers (`sk_destruct`, `sk_write_space`, `sk_backlog_rcv`, `sk_prot`) that become control-flow hijack primitives after heap grooming.\nA:H - The bug reliably produces a KASAN-reported slab-use-after-free and, without KASAN, dereferences of freed/reused socket memory and refcount corruption lead to kernel oops or panic."

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: zoned: fix calc_available_free_space() for zoned mode
calc_available_free_space() returns the total size of metadata (or
system) block groups, which can be allocated from unallocated disk
space. The logic is wrong on zoned mode in two places.
First, the calculation of data_chunk_size is wrong. We always allocate
one zone as one chunk, and no partial allocation of a zone. So, we
should use zone_size (= data_sinfo->chunk_size) as it is.
Second, the result "avail" may not be zone aligned. Since we always
allocate one zone as one chunk on zoned mode, returning non-zone size
aligned bytes will result in less pressure on the async metadata reclaim
process.
This is serious for the nearly full state with a large zone size device.
Allowing over-commit too much will result in less async reclaim work and
end up in ENOSPC. We can align down to the zone size to avoid that.

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/sclp: Prevent release of buffer in I/O
When a task waiting for completion of a Store Data operation is
interrupted, an attempt is made to halt this operation. If this attempt
fails due to a hardware or firmware problem, there is a chance that the
SCLP facility might store data into buffers referenced by the original
operation at a later time.
Handle this situation by not releasing the referenced data buffers if
the halt attempt fails. For current use cases, this might result in a
leak of few pages of memory in case of a rare hardware/firmware
malfunction.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_limit: reject configurations that cause integer overflow
Reject bogus configs where internal token counter wraps around.
This only occurs with very very large requests, such as 17gbyte/s.
Its better to reject this rather than having incorrect ratelimit.

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/pkey: Wipe copies of protected- and secure-keys
Although the clear-key of neither protected- nor secure-keys is
accessible, this key material should only be visible to the calling
process. So wipe all copies of protected- or secure-keys from stack,
even in case of an error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: txgbe: free isb resources at the right time
When using MSI/INTx interrupt, the shared interrupts are still being
handled in the device remove routine, before free IRQs. So isb memory
is still read after it is freed. Thus move wx_free_isb_resources()
from txgbe_close() to txgbe_remove(). And fix the improper isb free
action in txgbe_open() error handling path.

Received network frames cannot reach the code, since Rx and bus mastering are already disabled when the interface goes down.\nAC:L - Once the driver is in MSI/INTx mode (VMs, `pci=nomsi`, MSI-X vector exhaustion, and the ngbe 1G parts), the stale handler dereference is deterministic: after `ifdown` or during the multi-millisecond `txgbe_remove_phy()` window, the very next interrupt on the shared line hits the freed/NULL `isb_mem`, and the attacker can both generate that interrupt activity and repeat ifdown/ifup cycles to hit the narrow free-to-NULL window.\nPR:L - The trigger needs `CAP_NET_ADMIN` over the netdev\u0027s namespace, which is held by container/appliance \"root\" whenever a physical Wangxun port is delegated into a network namespace owned by a user namespace, so it is not a real-root-only operation. Any semi-privileged network-management context (NetworkManager helpers, orchestration agents, netns-delegated containers) can drive the close/unbind path.\nUI:N - The attacker performs the interface-down or unbind step themselves and the interrupt that faults arrives from ordinary ambient device activity; no action by another user or administrator is required.\nS:U - The freed DMA buffer, the faulting interrupt handler, and the resulting corruption/panic all live in the kernel\u0027s own security authority, with no crossing of a hypervisor, IOMMU, or sandbox boundary.\nC:H - Upstream describes the defect as isb memory \"still read after it is freed\" \u2014 `wx_misc_isb()` reads a page already returned to the page allocator and therefore potentially re-populated with arbitrary kernel data, and a use-after-free on attacker-groomable memory is treatable as an arbitrary-read primitive.\nI:H - Beyond the read, `txgbe_misc_irq_handle()` executes `wx-\u003eisb_mem[WX_ISB_VEC0] = 0`, a write into the freed page; with ifdown/ifup cycling plus heap spraying the attacker can control what occupies that page, turning a fixed-offset zeroing write into kernel memory corruption usable against refcounts, flags, or pointers.\nA:H - In the far larger post-`NULL`-store window the handler dereferences a NULL `isb_mem` from hard-IRQ context, producing an oops in interrupt context (\"Fatal exception in interrupt\") that panics the machine, and this is reproducible on every ifdown or module removal on an INTx-shared system."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/gma500: fix null pointer dereference in psb_intel_lvds_get_modes
In psb_intel_lvds_get_modes(), the return value of drm_mode_duplicate() is
assigned to mode, which will lead to a possible NULL pointer dereference
on failure of drm_mode_duplicate(). Add a check to avoid npd.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Add outer runtime_pm protection to xe_live_ktest@xe_dma_buf
Any kunit doing any memory access should get their own runtime_pm
outer references since they don't use the standard driver API
entries. In special this dma_buf from the same driver.
Found by pre-merge CI on adding WARN calls for unprotected
inner callers:

Summary
In the Linux kernel, the following vulnerability has been resolved:
cachestat: do not flush stats in recency check
syzbot detects that cachestat() is flushing stats, which can sleep, in its
RCU read section (see [1]). This is done in the workingset_test_recent()
step (which checks if the folio's eviction is recent).
Move the stat flushing step to before the RCU read section of cachestat,
and skip stat flushing during the recency check.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: mmc_test: Fix NULL dereference on allocation failure
If the "test->highmem = alloc_pages()" allocation fails then calling
__free_pages(test->highmem) will result in a NULL dereference. Also
change the error code to -ENOMEM instead of returning success.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Update error handler for UCTX and UMEM
In the fast unload flow, the device state is set to internal error,
which indicates that the driver started the destroy process.
In this case, when a destroy command is being executed, it should return
MLX5_CMD_STAT_OK.
Fix MLX5_CMD_OP_DESTROY_UCTX and MLX5_CMD_OP_DESTROY_UMEM to return OK
instead of EIO.
This fixes a call trace in the umem release process -

Summary
In the Linux kernel, the following vulnerability has been resolved:
sched: sch_cake: fix bulk flow accounting logic for host fairness
In sch_cake, we keep track of the count of active bulk flows per host,
when running in dst/src host fairness mode, which is used as the
round-robin weight when iterating through flows. The count of active
bulk flows is updated whenever a flow changes state.
This has a peculiar interaction with the hash collision handling: when a
hash collision occurs (after the set-associative hashing), the state of
the hash bucket is simply updated to match the new packet that collided,
and if host fairness is enabled, that also means assigning new per-host
state to the flow. For this reason, the bulk flow counters of the
host(s) assigned to the flow are decremented, before new state is
assigned (and the counters, which may not belong to the same host
anymore, are incremented again).
Back when this code was introduced, the host fairness mode was always
enabled, so the decrement was unconditional. When the configuration
flags were introduced the *increment* was made conditional, but
the *decrement* was not. Which of course can lead to a spurious
decrement (and associated wrap-around to U16_MAX).
AFAICT, when host fairness is disabled, the decrement and wrap-around
happens as soon as a hash collision occurs (which is not that common in
itself, due to the set-associative hashing). However, in most cases this
is harmless, as the value is only used when host fairness mode is
enabled. So in order to trigger an array overflow, sch_cake has to first
be configured with host fairness disabled, and while running in this
mode, a hash collision has to occur to cause the overflow. Then, the
qdisc has to be reconfigured to enable host fairness, which leads to the
array out-of-bounds because the wrapped-around value is retained and
used as an array index. It seems that syzbot managed to trigger this,
which is quite impressive in its own right.
This patch fixes the issue by introducing the same conditional check on
decrement as is used on increment.
The original bug predates the upstreaming of cake, but the commit listed
in the Fixes tag touched that code, meaning that this patch won't apply
before that.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: protect references to superblock parameters exposed in sysfs
The superblock buffers of nilfs2 can not only be overwritten at runtime
for modifications/repairs, but they are also regularly swapped, replaced
during resizing, and even abandoned when degrading to one side due to
backing device issues. So, accessing them requires mutual exclusion using
the reader/writer semaphore "nilfs->ns_sem".
Some sysfs attribute show methods read this superblock buffer without the
necessary mutual exclusion, which can cause problems with pointer
dereferencing and memory access, so fix it.

Unbounded, cheap retry against a continuously recurring window makes this reliably winnable.\nPR:L - The affected attributes are created with NILFS_DEV_RO_ATTR, i.e. mode 0444, so any unprivileged local user can read them with no capability whatsoever.

The unsynchronized pointer also lets the reader observe torn state (nilfs_dev_revision_show reloads sbp[0] twice across a swap), so kernel object state is consumed inconsistently.\nA:H - Dereferencing a superblock pointer that has been abandoned during degradation to one side, or that points into a released buffer_head\u0027s page, causes a kernel oops/panic \u2014 the commit explicitly cites \"problems with pointer dereferencing and memory access.\" Any such crash is High availability impact."

Summary
In the Linux kernel, the following vulnerability has been resolved:
md: fix deadlock between mddev_suspend and flush bio
Deadlock occurs when mddev is being suspended while some flush bio is in
progress. It is a complex issue.
T1. the first flush is at the ending stage, it clears 'mddev->flush_bio'
and tries to submit data, but is blocked because mddev is suspended
by T4.
T2. the second flush sets 'mddev->flush_bio', and attempts to queue
md_submit_flush_data(), which is already running (T1) and won't
execute again if on the same CPU as T1.
T3. the third flush inc active_io and tries to flush, but is blocked because
'mddev->flush_bio' is not NULL (set by T2).
T4. mddev_suspend() is called and waits for active_io dec to 0 which is inc
by T3.
T1 T2 T3 T4
(flush 1) (flush 2) (third 3) (suspend)
md_submit_flush_data
mddev->flush_bio = NULL;
.
. md_flush_request
. mddev->flush_bio = bio
. queue submit_flushes
. .
. . md_handle_request
. . active_io + 1
. . md_flush_request
. . wait !mddev->flush_bio
. .
. . mddev_suspend
. . wait !active_io
. .
. submit_flushes
. queue_work md_submit_flush_data
. //md_submit_flush_data is already running (T1)
.
md_handle_request
wait resume
The root issue is non-atomic inc/dec of active_io during flush process.
active_io is dec before md_submit_flush_data is queued, and inc soon
after md_submit_flush_data() run.
md_flush_request
active_io + 1
submit_flushes
active_io - 1
md_submit_flush_data
md_handle_request
active_io + 1
make_request
active_io - 1
If active_io is dec after md_handle_request() instead of within
submit_flushes(), make_request() can be called directly intead of
md_handle_request() in md_submit_flush_data(), and active_io will
only inc and dec once in the whole flush process. Deadlock will be
fixed.
Additionally, the only difference between fixing the issue and before is
that there is no return error handling of make_request(). But after
previous patch cleaned md_write_start(), make_requst() only return error
in raid5_make_request() by dm-raid, see commit 41425f96d7aa ("dm-raid456,
md/raid456: fix a deadlock for dm-raid456 while io concurrent with
reshape)". Since dm always splits data and flush operation into two
separate io, io size of flush submitted by dm always is 0, make_request()
will not be called in md_submit_flush_data(). To prevent future
modifications from introducing issues, add WARN_ON to ensure
make_request() no error is returned in this context.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: During vport delete send async logout explicitly
During vport delete, it is observed that during unload we hit a crash
because of stale entries in outstanding command array. For all these stale
I/O entries, eh_abort was issued and aborted (fast_fail_io = 2009h) but
I/Os could not complete while vport delete is in process of deleting.

Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/core: Implement a limit on UMAD receive List
The existing behavior of ib_umad, which maintains received MAD
packets in an unbounded list, poses a risk of uncontrolled growth.
As user-space applications extract packets from this list, the rate
of extraction may not match the rate of incoming packets, leading
to potential list overflow.
To address this, we introduce a limit to the size of the list. After
considering typical scenarios, such as OpenSM processing, which can
handle approximately 100k packets per second, and the 1-second retry
timeout for most packets, we set the list size limit to 200k. Packets
received beyond this limit are dropped, assuming they are likely timed
out by the time they are handled by user-space.
Notably, packets queued on the receive list due to reasons like
timed-out sends are preserved even when the list is full.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp_bpf: fix return value of tcp_bpf_sendmsg()
When we cork messages in psock->cork, the last message triggers the
flushing will result in sending a sk_msg larger than the current
message size. In this case, in tcp_bpf_send_verdict(), 'copied' becomes
negative at least in the following case:
468 case __SK_DROP:
469 default:
470 sk_msg_free_partial(sk, msg, tosend);
471 sk_msg_apply_bytes(psock, tosend);
472 *copied -= (tosend + delta); // <==== HERE
473 return -EACCES;
Therefore, it could lead to the following BUG with a proper value of
'copied' (thanks to syzbot). We should not use negative 'copied' as a
return value here.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cachefiles: add consistency check for copen/cread
This prevents malicious processes from completing random copen/cread
requests and crashing the system. Added checks are listed below:
* Generic, copen can only complete open requests, and cread can only
complete read requests.
* For copen, ondemand_id must not be 0, because this indicates that the
request has not been read by the daemon.
* For cread, the object corresponding to fd and req should be the same.

The corrupted request/object lifetimes in this exact code region are the same class that produced KASAN slab-use-after-free reads in the sibling fixes.\nI:H - `copen` on an arbitrary request lets the attacker set any object\u0027s `cookie-\u003eobject_size`, which drives `vfs_truncate()` of the backing cache file and the on-disk coherency xattr, and lets erofs-over-fscache mounts serve wrong or unfetched content \u2014 corrupting data and executables read from container images.\nA:H - The commit exists specifically to stop malicious processes \"crashing the system\"; completing requests out of band leaves objects marked open with `ondemand_id == 0` and no anon fd, so readers block permanently in uninterruptible `wait_for_completion()` (hung task / unkillable D-state), and leaked anon fds pin cookies so later mounts hang as well."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: mana: Fix RX buf alloc_size alignment and atomic op panic
The MANA driver's RX buffer alloc_size is passed into napi_build_skb() to
create SKB. skb_shinfo(skb) is located at the end of skb, and its alignment
is affected by the alloc_size passed into napi_build_skb(). The size needs
to be aligned properly for better performance and atomic operations.
Otherwise, on ARM64 CPU, for certain MTU settings like 4000, atomic
operations may panic on the skb_shinfo(skb)->dataref due to alignment fault.
To fix this bug, add proper alignment to the alloc_size calculation.
Sample panic info:

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Fix use-after-free bugs caused by sco_sock_timeout
When the sco connection is established and then, the sco socket
is releasing, timeout_work will be scheduled to judge whether
the sco disconnection is timeout. The sock will be deallocated
later, but it is dereferenced again in sco_sock_timeout. As a
result, the use-after-free bugs will happen. The root cause is
shown below:
Cleanup Thread | Worker Thread
sco_sock_release |
sco_sock_close |
__sco_sock_close |
sco_sock_set_timer |
schedule_delayed_work |
sco_sock_kill | (wait a time)
sock_put(sk) //FREE | sco_sock_timeout
| sock_hold(sk) //USE
The KASAN report triggered by POC is shown below:

Summary
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (adc128d818) Fix underflows seen when writing limit attributes
DIV_ROUND_CLOSEST() after kstrtol() results in an underflow if a large
negative number such as -9223372036854775808 is provided by the user.
Fix it by reordering clamp_val() and DIV_ROUND_CLOSEST() operations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: clean up our handling of refs == 0 in snapshot delete
In reada we BUG_ON(refs == 0), which could be unkind since we aren't
holding a lock on the extent leaf and thus could get a transient
incorrect answer. In walk_down_proc we also BUG_ON(refs == 0), which
could happen if we have extent tree corruption. Change that to return
-EUCLEAN. In do_walk_down() we catch this case and handle it correctly,
however we return -EIO, which -EUCLEAN is a more appropriate error code.
Finally in walk_up_proc we have the same BUG_ON(refs == 0), so convert
that to proper error handling. Also adjust the error message so we can
actually do something with the information.

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: cs_dsp: Validate payload length before processing block
Move the payload length check in cs_dsp_load() and cs_dsp_coeff_load()
to be done before the block is processed.
The check that the length of a block payload does not exceed the number
of remaining bytes in the firwmware file buffer was being done near the
end of the loop iteration. However, some code before that check used the
length field without validating it.

"value": "AV:N - The vulnerable retry path in drivers/nvme/host/core.c is driven by completion status taken directly off the wire from a remote NVMe-oF peer (nvme-tcp/rdma/fc), which selects the RETRY disposition, and by remote connection teardown, which forces the second cleanup. A malicious or compromised target \u2014 or an attacker injecting into a plaintext NVMe/TCP session on port 4420 \u2014 reaches this entirely over the network.\nAC:L - The remote peer deterministically controls both steps: return a non-DNR, non-path-related error status for a DSM/discard command to force the requeue, then close the connection so the re-dispatch hits nvme_fail_nonready_command()-\u003envme_host_path_error(). The requeue-to-reconnect window is seconds, so no race must be won and no uncontrolled state is required.\nPR:N - NVMe/TCP has no authentication or transport security in its default configuration, so the attacking target or network peer holds no credentials on the victim host. The host-side discards that carry the special payload are produced by routine filesystem activity, not by any privileged attacker action.\nUI:N - No victim action is needed \u2014 discard requests are generated automatically by mounted filesystems, fstrim, and swap on an already-connected NVMe-oF namespace. The attacker only has to respond to one that is already in flight.\nS:U - The heap corruption is confined to the kernel\u0027s own memory allocator and the compromise stays within the kernel\u0027s security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The double free re-inserts a live kmalloc-4k chunk into the freelist so two allocations receive the same memory, yielding a use-after-free/type-confusion primitive that permits reading adjacent kernel objects and leaking arbitrary kernel memory. SLUB\u0027s consecutive-double-free hardening does not catch it because many allocations occur between the two frees.\nI:H - The same overlapping-allocation primitive gives an attacker-groomable kernel write, the classic route to control-flow hijack and privilege escalation. In the shared discard_page variant, the extra clear_bit_unlock() breaks mutual exclusion so concurrent DSM commands share one range buffer and the device deallocates the wrong LBAs, silently destroying on-disk data.\nA:H - Freelist corruption from the double free reliably causes kernel panics, and where SLUB debugging/hardening does detect it the result is an immediate BUG. The trigger can be repeated on every retried discard, so the host can be crashed at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau/dispnv04: fix null pointer dereference in nv17_tv_get_hd_modes
In nv17_tv_get_hd_modes(), the return value of drm_mode_duplicate() is
assigned to mode, which will lead to a possible NULL pointer dereference
on failure of drm_mode_duplicate(). The same applies to drm_cvt_mode().
Add a check to avoid null pointer dereference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: keystone: Add workaround for Errata #i2037 (AM65x SR 1.0)
Errata #i2037 in AM65x/DRA80xM Processors Silicon Revision 1.0
(SPRZ452D_July 2018_Revised December 2019 [1]) mentions when an
inbound PCIe TLP spans more than two internal AXI 128-byte bursts,
the bus may corrupt the packet payload and the corrupt data may
cause associated applications or the processor to hang.
The workaround for Errata #i2037 is to limit the maximum read
request size and maximum payload size to 128 bytes. Add workaround
for Errata #i2037 here.
The errata and workaround is applicable only to AM65x SR 1.0 and
later versions of the silicon will have this fixed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix DEVMAP_HASH overflow check on 32-bit arches
The devmap code allocates a number hash buckets equal to the next power
of two of the max_entries value provided when creating the map. When
rounding up to the next power of two, the 32-bit variable storing the
number of buckets can overflow, and the code checks for overflow by
checking if the truncated 32-bit value is equal to 0. However, on 32-bit
arches the rounding up itself can overflow mid-way through, because it
ends up doing a left-shift of 32 bits on an unsigned long value. If the
size of an unsigned long is four bytes, this is undefined behaviour, so
there is no guarantee that we'll end up with a nice and tidy 0-value at
the end.
Syzbot managed to turn this into a crash on arm32 by creating a
DEVMAP_HASH with max_entries > 0x80000000 and then trying to update it.
Fix this by moving the overflow check to before the rounding up
operation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sched/deadline: Fix task_struct reference leak
During the execution of the following stress test with linux-rt:
stress-ng --cyclic 30 --timeout 30 --minimize --quiet
kmemleak frequently reported a memory leak concerning the task_struct:
unreferenced object 0xffff8881305b8000 (size 16136):
comm "stress-ng", pid 614, jiffies 4294883961 (age 286.412s)
object hex dump (first 32 bytes):

backtrace:
[<00000000046b6790>] dup_task_struct+0x30/0x540
[<00000000c5ca0f0b>] copy_process+0x3d9/0x50e0

[<00000000552900ff>] entry_SYSCALL_64_after_hwframe+0x6e/0x76
The issue occurs in start_dl_timer(), which increments the task_struct
reference count and sets a timer. The timer callback, dl_task_timer,
is supposed to decrement the reference count upon expiration. However,
if enqueue_task_dl() is called before the timer expires and cancels it,
the reference count is not decremented, leading to the leak.
This patch fixes the reference leak by ensuring the task_struct
reference count is properly decremented when the timer is canceled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gem: Fix Virtual Memory mapping boundaries calculation
Calculating the size of the mapped area as the lesser value
between the requested size and the actual size does not consider
the partial mapping offset. This can cause page fault access.
Fix the calculation of the starting and ending addresses, the
total size is now deduced from the difference between the end and
start addresses.
Additionally, the calculations have been rewritten in a clearer
and more understandable form.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/shmem: disable PMD-sized page cache if needed
For shmem files, it's possible that PMD-sized page cache can't be
supported by xarray. For example, 512MB page cache on ARM64 when the base
page size is 64KB can't be supported by xarray. It leads to errors as the
following messages indicate when this sort of xarray entry is split.

Fix it by disabling PMD-sized page cache when HPAGE_PMD_ORDER is larger
than MAX_PAGECACHE_ORDER. As Matthew Wilcox pointed, the page cache in a
shmem file isn't represented by a multi-index entry and doesn't have this
limitation when the xarry entry is split until commit 6b24ca4a1a8d ("mm:
Use multi-index entries in the page cache").

Summary
In the Linux kernel, the following vulnerability has been resolved:
ethtool: check device is present when getting link settings
A sysfs reader can race with a device reset or removal, attempting to
read device state when the device is not actually present. eg:
[exception RIP: qed_get_current_link+17]
#8 [ffffb9e4f2907c48] qede_get_link_ksettings at ffffffffc07a994a [qede]
#9 [ffffb9e4f2907cd8] __rh_call_get_link_ksettings at ffffffff992b01a3
#10 [ffffb9e4f2907d38] __ethtool_get_link_ksettings at ffffffff992b04e4
#11 [ffffb9e4f2907d90] duplex_show at ffffffff99260300
#12 [ffffb9e4f2907e38] dev_attr_show at ffffffff9905a01c
#13 [ffffb9e4f2907e50] sysfs_kf_seq_show at ffffffff98e0145b
#14 [ffffb9e4f2907e68] seq_read at ffffffff98d902e3
#15 [ffffb9e4f2907ec8] vfs_read at ffffffff98d657d1
#16 [ffffb9e4f2907f00] ksys_read at ffffffff98d65c3f
#17 [ffffb9e4f2907f38] do_syscall_64 at ffffffff98a052fb
crash> struct net_device.state ffff9a9d21336000
state = 5,
state 5 is __LINK_STATE_START (0b1) and __LINK_STATE_NOCARRIER (0b100).
The device is not present, note lack of __LINK_STATE_PRESENT (0b10).
This is the same sort of panic as observed in commit 4224cfd7fb65
("net-sysfs: add check for netdevice being present to speed_show").
There are many other callers of __ethtool_get_link_ksettings() which
don't have a device presence check.
Move this check into ethtool to protect all callers.

cxl/region: Avoid null pointer dereference in region lookup
cxl_dpa_to_region() looks up a region based on a memdev and DPA.
It wrongly assumes an endpoint found mapping the DPA is also of
a fully assembled region. When not true it leads to a null pointer
dereference looking up the region name.
This appears during testing of region lookup after a failure to
assemble a BIOS defined region or if the lookup raced with the
assembly of the BIOS defined region.
Failure to clean up BIOS defined regions that fail assembly is an
issue in itself and a fix to that problem will alleviate some of
the impact. It will not alleviate the race condition so let's harden
this path.
The behavior change is that the kernel oops due to a null pointer
dereference is replaced with a dev_dbg() message noting that an
endpoint was mapped.
Additional comments are added so that future users of this function
can more clearly understand what it provides.

Per kernel scoring guidance, an out-of-bounds write is High.\nA:H - After the write, `bw_params` is a wild pointer dereferenced throughout `rn_clk_mgr`/DML on every clock update, producing an oops or panic; because it recurs on each GPU resume, the system is left unusable rather than transiently degraded."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: don't allow mapping the MMIO HDP page with large pages
We don't get the right offset in that case. The GPU has
an unused 4K area of the register BAR space into which you can
remap registers. We remap the HDP flush registers into this
space to allow userspace (CPU or GPU) to flush the HDP when it
updates VRAM. However, on systems with >4K pages, we end up
exposing PAGE_SIZE of MMIO space.

"value": "AV:L - The vulnerability is reached only through the local /dev/kfd character device via the AMDKFD_IOC_ALLOC_MEMORY_OF_GPU ioctl followed by mmap() on the same file descriptor. There is no remote or network-facing path to kfd_mmio_mmap().\nAC:L - On an affected system exploitation is fully deterministic \u2014 no race, no heap grooming, no memory-layout dependency; the attacker simply issues one ioctl and one mmap and reads back a fixed register window. Per CVSS the vulnerable configuration (a \u003e4K PAGE_SIZE kernel, which is the distro default on RHEL aarch64 and ppc64le, the very hosts paired with MI100/MI200 accelerators) is assumed rather than scored as added complexity, and the attacker can trivially confirm it with getpagesize().\nPR:L - kfd_open() performs no capability check and AMDKFD_IOC_ALLOC_MEMORY_OF_GPU is registered with flags 0, so neither CAP_SYS_ADMIN nor CAP_CHECKPOINT_RESTORE is required anywhere along the path. Any local user able to open /dev/kfd \u2014 which ROCm installs expose as 0666 or to the render/video group \u2014 can perform the mapping.\nUI:N - The attacking process performs the ioctl and mmap entirely on its own file descriptor with no victim involvement. No other user needs to open a file, mount a filesystem, or run any GPU workload.\nS:U - The exposed MMIO belongs to a device managed by the same kernel that is compromised, so the vulnerable and impacted resources fall under a single security authority. This is a standard local kernel privilege-escalation primitive rather than a hypervisor or host-IOMMU boundary crossing, and the remap is disabled entirely under SR-IOV.\nC:H - Instead of a 4KB HDP-flush window, userspace obtains readable access to ~60KB of live GPU register space, and on Arcturus/Aldebaran that window contains the SDMA2\u2013SDMA7 register blocks. Control of a DMA engine\u0027s ring registers yields an arbitrary memory read primitive and permits reading other ROCm processes\u0027 or tenants\u0027 GPU memory by bypassing GPUVM isolation.\nI:H - The mapping is created with PROT_WRITE honoured via io_remap_pfn_range(), giving unprivileged userspace direct write access to DMA-engine ring base/control registers such as mmSDMA2_GFX_RB_BASE. An attacker can point an SDMA ring at attacker-authored command packets and obtain arbitrary DMA writes, escalating to full kernel compromise.\nA:H - Writing arbitrary values into the exposed SDMA/GC control registers immediately wedges the DMA engines and triggers GPU hangs, ring timeouts and device resets, and on many configurations an unrecoverable GPU reset takes down the whole graphics/compute stack. The write is unconditional and repeatable, so a trivial loop reliably denies service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: handle 2x996 RU allocation in cfg80211_calculate_bitrate_he()
Currently NL80211_RATE_INFO_HE_RU_ALLOC_2x996 is not handled in
cfg80211_calculate_bitrate_he(), leading to below warning:
kernel: invalid HE MCS: bw:6, ru:6
kernel: WARNING: CPU: 0 PID: 2312 at net/wireless/util.c:1501 cfg80211_calculate_bitrate_he+0x22b/0x270 [cfg80211]
Fix it by handling 2x996 RU allocation in the same way as 160 MHz bandwidth.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fail bpf_timer_cancel when callback is being cancelled
Given a schedule:
timer1 cb timer2 cb
bpf_timer_cancel(timer2); bpf_timer_cancel(timer1);
Both bpf_timer_cancel calls would wait for the other callback to finish
executing, introducing a lockup.
Add an atomic_t count named 'cancelling' in bpf_hrtimer. This keeps
track of all in-flight cancellation requests for a given BPF timer.
Whenever cancelling a BPF timer, we must check if we have outstanding
cancellation requests, and if so, we must fail the operation with an
error (-EDEADLK) since cancellation is synchronous and waits for the
callback to finish executing. This implies that we can enter a deadlock
situation involving two or more timer callbacks executing in parallel
and attempting to cancel one another.
Note that we avoid incrementing the cancelling counter for the target
timer (the one being cancelled) if bpf_timer_cancel is not invoked from
a callback, to avoid spurious errors. The whole point of detecting
cur->cancelling and returning -EDEADLK is to not enter a busy wait loop
(which may or may not lead to a lockup). This does not apply in case the
caller is in a non-callback context, the other side can continue to
cancel as it sees fit without running into errors.
Background on prior attempts:
Earlier versions of this patch used a bool 'cancelling' bit and used the
following pattern under timer->lock to publish cancellation status.
lock(t->lock);
t->cancelling = true;
mb();
if (cur->cancelling)
return -EDEADLK;
unlock(t->lock);
hrtimer_cancel(t->timer);
t->cancelling = false;
The store outside the critical section could overwrite a parallel
requests t->cancelling assignment to true, to ensure the parallely
executing callback observes its cancellation status.
It would be necessary to clear this cancelling bit once hrtimer_cancel
is done, but lack of serialization introduced races. Another option was
explored where bpf_timer_start would clear the bit when (re)starting the
timer under timer->lock. This would ensure serialized access to the
cancelling bit, but may allow it to be cleared before in-flight
hrtimer_cancel has finished executing, such that lockups can occur
again.
Thus, we choose an atomic counter to keep track of all outstanding
cancellation requests and use it to prevent lockups in case callbacks
attempt to cancel each other while executing in parallel.

This would ensure serialized access to the\ncancelling bit, but may allow it to be cleared before in-flight\nhrtimer_cancel has finished executing, such that lockups can occur\nagain.\n\nThus, we choose an atomic counter to keep track of all outstanding\ncancellation requests and use it to prevent lockups in case callbacks\nattempt to cancel each other while executing in parallel."

Summary
In the Linux kernel, the following vulnerability has been resolved:
cgroup/cpuset: Prevent UAF in proc_cpuset_show()
An UAF can happen when /proc/cpuset is read as reported in [1].
This can be reproduced by the following methods:
1.add an mdelay(1000) before acquiring the cgroup_lock In the
cgroup_path_ns function.
2.$cat /proc/<pid>/cpuset repeatly.
3.$mount -t cgroup -o cpuset cpuset /sys/fs/cgroup/cpuset/
$umount /sys/fs/cgroup/cpuset/ repeatly.
The race that cause this bug can be shown as below:
(umount) | (cat /proc/<pid>/cpuset)
css_release | proc_cpuset_show
css_release_work_fn | css = task_get_css(tsk, cpuset_cgrp_id);
css_free_rwork_fn | cgroup_path_ns(css->cgroup, ...);
cgroup_destroy_root | mutex_lock(&cgroup_mutex);
rebind_subsystems |
cgroup_free_root |
| // cgrp was freed, UAF
| cgroup_path_ns_locked(cgrp,..);
When the cpuset is initialized, the root node top_cpuset.css.cgrp
will point to &cgrp_dfl_root.cgrp. In cgroup v1, the mount operation will
allocate cgroup_root, and top_cpuset.css.cgrp will point to the allocated
&cgroup_root.cgrp. When the umount operation is executed,
top_cpuset.css.cgrp will be rebound to &cgrp_dfl_root.cgrp.
The problem is that when rebinding to cgrp_dfl_root, there are cases
where the cgroup_root allocated by setting up the root for cgroup v1
is cached. This could lead to a Use-After-Free (UAF) if it is
subsequently freed. The descendant cgroups of cgroup v1 can only be
freed after the css is released. However, the css of the root will never
be released, yet the cgroup_root should be freed when it is unmounted.
This means that obtaining a reference to the css of the root does
not guarantee that css.cgrp->root will not be freed.
Fix this problem by using rcu_read_lock in proc_cpuset_show().
As cgroup_root is kfree_rcu after commit d23b5c577715
("cgroup: Make operations on the cgroup root_list RCU safe"),
css->cgroup won't be freed during the critical section.
To call cgroup_path_ns_locked, css_set_lock is needed, so it is safe to
replace task_get_css with task_css.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dev/parport: fix the array out-of-bounds risk
Fixed array out-of-bounds issues caused by sprintf
by replacing it with snprintf for safer data copying,
ensuring the destination buffer is not overflowed.
Below is the stack trace I encountered during the actual issue:
[ 66.575408s] [pid:5118,cpu4,QThread,4]Kernel panic - not syncing: stack-protector:

No capability, root, or namespace privilege is involved.\nUI:N - The attacker performs the read themselves; no victim action, mount, or configuration change by another user is required.\nS:U - The corruption is confined to the kernel stack of the calling task within the same security authority; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - This is a stack buffer overflow past a 20-byte (and 256-byte) buffer that overwrites adjacent stack state including saved registers and the return address; in the do_autoprobe() variant the overflowing bytes are fully attacker-controlled Device ID data, giving corruption that can be leveraged into arbitrary kernel memory disclosure.\nI:H - An out-of-bounds stack write is an arbitrary-write primitive against the kernel stack, and via do_autoprobe() the written content is attacker-supplied and unbounded (~800+ bytes), making control-flow hijack and arbitrary kernel modification achievable.\nA:H - The reported real-world effect is \"Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in do_hardware_base_addr\", i.e. a full system crash that any local user can trigger on demand and repeatedly."

Summary
In the Linux kernel, the following vulnerability has been resolved:
PM / devfreq: Fix buffer overflow in trans_stat_show
Fix buffer overflow in trans_stat_show().
Convert simple snprintf to the more secure scnprintf with size of
PAGE_SIZE.
Add condition checking if we are exceeding PAGE_SIZE and exit early from
loop. Also add at the end a warning that we exceeded PAGE_SIZE and that
stats is disabled.
Return -EFBIG in the case where we don't have enough space to write the
full transition table.
Also document in the ABI that this function can return -EFBIG error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
leds: an30259a: Use devm_mutex_init() for mutex initialization
In this driver LEDs are registered using devm_led_classdev_register()
so they are automatically unregistered after module's remove() is done.
led_classdev_unregister() calls module's led_set_brightness() to turn off
the LEDs and that callback uses mutex which was destroyed already
in module's remove() so use devm API instead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net, sunrpc: Remap EPERM in case of connection failure in xs_tcp_setup_socket
When using a BPF program on kernel_connect(), the call can return -EPERM. This
causes xs_tcp_setup_socket() to loop forever, filling up the syslog and causing
the kernel to potentially freeze up.
Neil suggested:
This will propagate -EPERM up into other layers which might not be ready
to handle it. It might be safer to map EPERM to an error we would be more
likely to expect from the network system - such as ECONNREFUSED or ENETDOWN.
ECONNREFUSED as error seems reasonable. For programs setting a different error
can be out of reach (see handling in 4fbac77d2d09) in particular on kernels
which do not have f10d05966196 ("bpf: Make BPF_PROG_RUN_ARRAY return -err
instead of allow boolean"), thus given that it is better to simply remap for
consistent behavior. UDP does handle EPERM in xs_udp_send_request().

The double-fetch write variant in jfs_listxattr() is likewise attacker-paced, since they control both the heap churn adjacent to the inline-EA slab object and the rate of syscalls.\nPR:L - On desktop, kiosk and workstation deployments removable media is mounted for the logged-in unprivileged user by udisks2/autofs, after which any unprivileged local user can trigger the overread on the crafted file. No CAP_SYS_ADMIN is needed for the triggering getxattr()/listxattr() calls themselves.\nUI:N - Once the filesystem is present, the attacker triggers the bug entirely on their own by calling getxattr()/listxattr() on their crafted file \u2014 even an `ls -l` style permission check reaches it via jfs_get_acl(). No victim action is required at exploitation time.\nS:U - The out-of-bounds access and its consequences are confined to the kernel\u0027s own memory and the same security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - An attacker-chosen valuelen of up to 65535 makes __jfs_getxattr() memcpy up to 64 KB from beyond the EA buffer \u2014 frequently the 128-byte i_inline_ea field inside a jfs_inode_info slab object \u2014 and that adjacent kernel heap is returned directly to userspace. This is a large, unbounded infoleak that can disclose kernel pointers, keys, and other tasks\u0027 data.\nI:H - jfs_listxattr() re-derives namelen, the os2-prefix decision, and NEXT_EA() from out-of-bounds memory in both its sizing pass and its copy pass, so a concurrent change to those bytes lets the copy pass overflow the kvmalloc\u0027d klist buffer \u2014 a kernel heap out-of-bounds write. Additionally, out-of-bounds heap bytes are parsed as POSIX ACL entries by jfs_get_acl(), corrupting the access rules applied to the inode.\nA:H - Reading up to 64 KB past a 128-byte inline buffer or a metapage routinely walks into unmapped pages, producing a general protection fault or oops, and KASAN/hardened configurations panic on the slab overread. The heap overflow write in jfs_listxattr() likewise corrupts allocator state and crashes the kernel."

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: sunxi-ng: common: Don't call hw_to_ccu_common on hw without common
In order to set the rate range of a hw sunxi_ccu_probe calls
hw_to_ccu_common() assuming all entries in desc->ccu_clks are contained
in a ccu_common struct. This assumption is incorrect and, in
consequence, causes invalid pointer de-references.
Remove the faulty call. Instead, add one more loop that iterates over
the ccu_clks and sets the rate range, if required.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: prevent derefencing NULL ptr in pfn_section_valid()
Commit 5ec8e8ea8b77 ("mm/sparsemem: fix race in accessing
memory_section->usage") changed pfn_section_valid() to add a READ_ONCE()
call around "ms->usage" to fix a race with section_deactivate() where
ms->usage can be cleared. The READ_ONCE() call, by itself, is not enough
to prevent NULL pointer dereference. We need to check its value before
dereferencing it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: virt_wifi: avoid reporting connection success with wrong SSID
When user issues a connection with a different SSID than the one
virt_wifi has advertised, the __cfg80211_connect_result() will
trigger the warning: WARN_ON(bss_not_found).
The issue is because the connection code in virt_wifi does not
check the SSID from user space (it only checks the BSSID), and
virt_wifi will call cfg80211_connect_result() with WLAN_STATUS_SUCCESS
even if the SSID is different from the one virt_wifi has advertised.
Eventually cfg80211 won't be able to find the cfg80211_bss and generate
the warning.
Fixed it by checking the SSID (from user space) in the connection code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/filemap: skip to create PMD-sized page cache if needed
On ARM64, HPAGE_PMD_ORDER is 13 when the base page size is 64KB. The
PMD-sized page cache can't be supported by xarray as the following error
messages indicate.

Fix it by skipping to allocate PMD-sized page cache when its size is
larger than MAX_PAGECACHE_ORDER. For this specific case, we will fall to
regular path where the readahead window is determined by BDI's sysfs file
(read_ahead_kb).

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: can: j1939: Initialize unused data in j1939_send_one()
syzbot reported kernel-infoleak in raw_recvmsg() [1]. j1939_send_one()
creates full frame including unused data, but it doesn't initialize
it. This causes the kernel-infoleak issue. Fix this by initializing
unused data.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vfs: Don't evict inode under the inode lru traversing context
The inode reclaiming process(See function prune_icache_sb) collects all
reclaimable inodes and mark them with I_FREEING flag at first, at that
time, other processes will be stuck if they try getting these inodes
(See function find_inode_fast), then the reclaiming process destroy the
inodes by function dispose_list(). Some filesystems(eg. ext4 with
ea_inode feature, ubifs with xattr) may do inode lookup in the inode
evicting callback function, if the inode lookup is operated under the
inode lru traversing context, deadlock problems may happen.
Case 1: In function ext4_evict_inode(), the ea inode lookup could happen
if ea_inode feature is enabled, the lookup process will be stuck
under the evicting context like this:
1. File A has inode i_reg and an ea inode i_ea
2. getfattr(A, xattr_buf) // i_ea is added into lru // lru->i_ea
3. Then, following three processes running like this:
PA PB
echo 2 > /proc/sys/vm/drop_caches
shrink_slab
prune_dcache_sb
// i_reg is added into lru, lru->i_ea->i_reg
prune_icache_sb
list_lru_walk_one
inode_lru_isolate
i_ea->i_state |= I_FREEING // set inode state
inode_lru_isolate
__iget(i_reg)
spin_unlock(&i_reg->i_lock)
spin_unlock(lru_lock)
rm file A
i_reg->nlink = 0
iput(i_reg) // i_reg->nlink is 0, do evict
ext4_evict_inode
ext4_xattr_delete_inode
ext4_xattr_inode_dec_ref_all
ext4_xattr_inode_iget
ext4_iget(i_ea->i_ino)
iget_locked
find_inode_fast
__wait_on_freeing_inode(i_ea) ----→ AA deadlock
dispose_list // cannot be executed by prune_icache_sb
wake_up_bit(&i_ea->i_state)
Case 2: In deleted inode writing function ubifs_jnl_write_inode(), file
deleting process holds BASEHD's wbuf->io_mutex while getting the
xattr inode, which could race with inode reclaiming process(The
reclaiming process could try locking BASEHD's wbuf->io_mutex in
inode evicting function), then an ABBA deadlock problem would
happen as following:
1. File A has inode ia and a xattr(with inode ixa), regular file B has
inode ib and a xattr.
2. getfattr(A, xattr_buf) // ixa is added into lru // lru->ixa
3. Then, following three processes running like this:
PA PB PC
echo 2 > /proc/sys/vm/drop_caches
shrink_slab
prune_dcache_sb
// ib and ia are added into lru, lru->ixa->ib->ia
prune_icache_sb
list_lru_walk_one
inode_lru_isolate
ixa->i_state |= I_FREEING // set inode state
inode_lru_isolate
__iget(ib)
spin_unlock(&ib->i_lock)
spin_unlock(lru_lock)
rm file B
ib->nlink = 0
rm file A
iput(ia)
ubifs_evict_inode(ia)
ubifs_jnl_delete_inode(ia)
ubifs_jnl_write_inode(ia)
make_reservation(BASEHD) // Lock wbuf->io_mutex
ubifs_iget(ixa->i_ino)
iget_locked
find_inode_fast
__wait_on_freeing_inode(ixa)
| iput(ib) // ib->nlink is 0, do evict
| ubifs_evict_inode
| ubifs_jnl_delete_inode(ib)
↓ ubifs_jnl_write_inode
ABBA deadlock ←-----make_reservation(BASEHD)
dispose_list // cannot be executed by prune_icache_sb
wake_up_bit(&ixa->i_state)
Fix the possible deadlock by using new inode state flag I_LRU_ISOLATING
to pin the inode in memory while inode_lru_isolate(

Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to don't dirty inode for readonly filesystem
syzbot reports f2fs bug as below:
kernel BUG at fs/f2fs/inode.c:933!
RIP: 0010:f2fs_evict_inode+0x1576/0x1590 fs/f2fs/inode.c:933

The root cause is:
- do_sys_open
- f2fs_lookup
- __f2fs_find_entry
- f2fs_i_depth_write
- f2fs_mark_inode_dirty_sync
- f2fs_dirty_inode
- set_inode_flag(inode, FI_DIRTY_INODE)
- umount
- kill_f2fs_super
- kill_block_super
- generic_shutdown_super
- sync_filesystem
: sb is readonly, skip sync_filesystem()
- evict_inodes
- iput
- f2fs_evict_inode
- f2fs_bug_on(sbi, is_inode_flag_set(inode, FI_DIRTY_INODE))
: trigger kernel panic
When we try to repair i_current_depth in readonly filesystem, let's
skip dirty inode to avoid panic in later f2fs_evict_inode().

"value": "AV:L - The vulnerability is reached through local filesystem operations on a mounted f2fs volume \u2014 a path lookup, posix_fadvise(POSIX_FADV_WILLNEED), F2FS_IOC_PRECACHE_EXTENTS, or fiemap \u2014 with the assertion firing during inode eviction. There is no network-facing path into fs/f2fs/inode.c.\nAC:L - The trigger is fully deterministic with no race: one dirtying operation on a read-only f2fs mount guarantees FI_DIRTY_INODE survives to f2fs_evict_inode, since sync_filesystem() is unconditionally skipped for read-only superblocks. CONFIG_F2FS_CHECK_FS turns it into a hard BUG(), but the defect is not conditional on it \u2014 default configs still WARN and free the inode with a dangling sbi-\u003einode_list[DIRTY_META] entry.\nPR:L - An unprivileged local user with only read access to a file on a read-only f2fs mount can dirty the inode; f2fs_ioc_precache_extents() and f2fs_file_fadvise() perform no capability, ownership, or mnt_want_write check, and the __f2fs_find_entry depth-repair path needs nothing beyond stat(). Read-only f2fs volumes are routine on Android and embedded systems where any app can reach them.\nUI:N - The attacker performs the entire dirtying step alone; the eviction that fires the assertion happens during ordinary automatic system activity \u2014 volume unmount by vold/udisks2, media eject, or shutdown \u2014 rather than requiring a victim to be tricked into any action. On desktops where udisks2 permits console-user mount/unmount of removable media, the attacker controls the whole chain unaided.\nS:U - The corruption and its consequences are confined to the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - In default configurations f2fs_bug_on degrades to WARN_ON, so execution continues and f2fs_free_inode() releases the 1200-byte f2fs_inode_info while fi-\u003egdirty_list is still linked into sbi-\u003einode_list[DIRTY_META]; subsequent traversal of that list (f2fs_sync_inode_meta) reads through the freed, sprayable slab object. This is the same stale-gdirty_list use-after-free syzbot reported at this assertion site.\nI:H - The dangling DIRTY_META list node gives a write primitive \u2014 the next f2fs_inode_dirtied(sync=true) performs list_add_tail(), whose __list_add() writes a kernel pointer through head-\u003eprev into the freed and potentially reallocated f2fs_inode_cache object. Heap-sprayable slab corruption of this kind is exploitable for control-flow hijacking.\nA:H - With CONFIG_F2FS_CHECK_FS the f2fs_bug_on at fs/f2fs/inode.c:933 is a BUG_ON that panics the kernel mid-unmount, exactly as syzbot reported; without it the WARN_ON still panics under panic_on_warn and leaves the filesystem flagged SBI_NEED_FSCK. Either way the result is a full denial of service."

"value": "AV:L - The vulnerability is triggered by a write(2) to the cgroup v1 file `cgroup.event_control` on a locally mounted cgroupfs hierarchy. There is no network-reachable path to `memcg_write_event_control()`.\nAC:L - The attacker fully controls the write length and content, so the out-of-bounds read past the end of the `kmalloc(len+1)` buffer is 100% deterministic; sizing the write to exactly 4095 bytes places the buffer at a page boundary, and heap/page grooming lets the attacker steer the unbounded `memparse()` walk into an unmapped page. cgroup v1 with the memory controller is a widely deployed default (Android, legacy/hybrid systemd, embedded), not a rare config.\nPR:L - `cgroup.event_control` was flagged `CFTYPE_WORLD_WRITABLE` (mode 0666), so any unprivileged local user can write it wherever a cgroup v1 memory hierarchy is mounted; additionally `cgroup_fs_type` has `FS_USERNS_MOUNT` and `cgroup1_get_tree()` only requires `ns_capable(user_ns, CAP_SYS_ADMIN)`, obtainable via `unshare -Urmc`.\nUI:N - A single write() syscall from the attacker\u0027s own process triggers the bug; no victim action, mount by an administrator, or other user involvement is required.\nS:U - The out-of-bounds read and the resulting oops occur entirely within the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The read runs off the end of the slab object and, via `memparse()`/`simple_strtoull()`, continues unbounded until a non-digit byte (and up to 19 bytes via `kstrndup()` on the vmpressure path), so it is not strictly bounded to a few bytes. The parsed adjacent-heap value is installed as a memcg usage threshold that the attacker can read back by driving cgroup memory usage and observing eventfd notifications, giving a genuine kernel-memory disclosure channel.\nI:N - The defect is purely an out-of-bounds read; no memory is written out of bounds and no attacker-controlled write primitive is created. The only state change is a threshold value inside the attacker\u0027s own cgroup, which they could already set directly by supplying an explicit args field.\nA:H - The unbounded read past a page-aligned kmalloc-4k object can reach an unmapped page and produce a kernel oops, exactly as described by the fix (\"user-triggerable oops\"); on KASAN or DEBUG_PAGEALLOC kernels the fault is deterministic and repeatable."
