The system was under memory stress where driver was not able to allocate an
SRB to carry out error recovery of cable pull. The failure to flush causes
upper layer to start modifying scsi_cmnd. When the system frees up some
memory, the subsequent cable pull trigger another command flush. At this
point the driver access a null pointer when attempting to DMA unmap the
SGL.
Add a check to make sure commands are flush back on session tear down to
prevent the null pointer access.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix race when detecting delalloc ranges during fiemap
For fiemap we recently stopped locking the target extent range for the
whole duration of the fiemap call, in order to avoid a deadlock in a
scenario where the fiemap buffer happens to be a memory mapped range of
the same file. This use case is very unlikely to be useful in practice but
it may be triggered by fuzz testing (syzbot, etc).
This however introduced a race that makes us miss delalloc ranges for
file regions that are currently holes, so the caller of fiemap will not
be aware that there's data for some file regions. This can be quite
serious for some use cases - for example in coreutils versions before 9.0,
the cp program used fiemap to detect holes and data in the source file,
copying only regions with data (extents or delalloc) from the source file
to the destination file in order to preserve holes (see the documentation
for its --sparse command line option). This means that if cp was used
with a source file that had delalloc in a hole, the destination file could
end up without that data, which is effectively a data loss issue, if it
happened to hit the race described below.
The race happens like this:
1) Fiemap is called, without the FIEMAP_FLAG_SYNC flag, for a file that
has delalloc in the file range [64M, 65M[, which is currently a hole;
2) Fiemap locks the inode in shared mode, then starts iterating the
inode's subvolume tree searching for file extent items, without having
the whole fiemap target range locked in the inode's io tree - the
change introduced recently by commit b0ad381fa769 ("btrfs: fix
deadlock with fiemap and extent locking"). It only locks ranges in
the io tree when it finds a hole or prealloc extent since that
commit;
3) Note that fiemap clones each leaf before using it, and this is to
avoid deadlocks when locking a file range in the inode's io tree and
the fiemap buffer is memory mapped to some file, because writing
to the page with btrfs_page_mkwrite() will wait on any ordered extent
for the page's range and the ordered extent needs to lock the range
and may need to modify the same leaf, therefore leading to a deadlock
on the leaf;
4) While iterating the file extent items in the cloned leaf before
finding the hole in the range [64M, 65M[, the delalloc in that range
is flushed and its ordered extent completes - meaning the corresponding
file extent item is in the inode's subvolume tree, but not present in
the cloned leaf that fiemap is iterating over;
5) When fiemap finds the hole in the [64M, 65M[ range by seeing the gap in
the cloned leaf (or a file extent item with disk_bytenr == 0 in case
the NO_HOLES feature is not enabled), it will lock that file range in
the inode's io tree and then search for delalloc by checking for the
EXTENT_DELALLOC bit in the io tree for that range and ordered extents
(with btrfs_find_delalloc_in_range()). But it finds nothing since the
delalloc in that range was already flushed and the ordered extent
completed and is gone - as a result fiemap will not report that there's
delalloc or an extent for the range [64M, 65M[, so user space will be
mislead into thinking that there's a hole in that range.
This could actually be sporadically triggered with test case generic/094
from fstests, which reports a missing extent/delalloc range like this:
generic/094 2s ... - output mismatch (see /home/fdmanana/git/hub/xfstests/results//generic/094.out.bad)

Summary
In the Linux kernel, the following vulnerability has been resolved:
ARM: 9359/1: flush: check if the folio is reserved for no-mapping addresses
Since commit a4d5613c4dc6 ("arm: extend pfn_valid to take into account
freed memory map alignment") changes the semantics of pfn_valid() to check
presence of the memory map for a PFN. A valid page for an address which
is reserved but not mapped by the kernel[1], the system crashed during
some uio test with the following memory layout:
node 0: [mem 0x00000000c0a00000-0x00000000cc8fffff]
node 0: [mem 0x00000000d0000000-0x00000000da1fffff]
the uio layout is：0xc0900000, 0x100000
the crash backtrace like:
Unable to handle kernel paging request at virtual address bff00000
[...]

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sparx5: Fix use after free inside sparx5_del_mact_entry
Based on the static analyzis of the code it looks like when an entry
from the MAC table was removed, the entry was still used after being
freed. More precise the vid of the mac_entry was used after calling
devm_kfree on the mac_entry.
The fix consists in first using the vid of the mac_entry to delete the
entry from the HW and after that to free it.

The attacker controls both the MAC/VID that populates the table and the trigger (moving the same source MAC between ports forces br_fdb_update() to emit the delete notification synchronously), so it is reproducible on demand.\nPR:N - The frame-driven path requires no credentials or account on the switch whatsoever \u2014 MAC learning, roaming, and FDB aging are automatic. The privileged `bridge fdb del` route is only an alternative, strictly weaker trigger.\nUI:N - No victim action is needed; bridge MAC learning, roaming and aging happen automatically in response to attacker-sent frames on an already-configured bridged switch port.\nS:U - The freed object and the corrupted state are both kernel-resident within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - Freed slab memory is read back and acted upon, and the object lives in a general kmalloc cache that concurrent GFP_ATOMIC softirq allocations (including the driver\u0027s own attacker-driven switchdev work and skb allocations) can immediately reoccupy, letting an attacker influence and infer freed heap contents. Per use-after-free scoring, UAF primitives generalize to kernel memory disclosure.\nI:H - The stale value read from freed memory is written directly into the hardware MAC-table unlearn command, so the wrong VID is unlearned \u2014 the attacker\u0027s revoked MAC stays programmed and forwarded in hardware while an unrelated victim\u0027s entry can be purged, corrupting switch forwarding and isolation state. As a use-after-free it also carries the general potential for heap-grooming-based write primitives.\nA:H - Dereferencing freed slab memory can oops outright \u2014 the kfree() immediately preceding the read can discard the last-in-use slab page back to the page allocator \u2014 and KASAN/hardened kernels report or panic on it. The attacker can retrigger it continuously by flooding frames with rotating source MACs, and corrupted MAC-table state causes persistent forwarding breakage."

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm-raid: really frozen sync_thread during suspend
1) commit f52f5c71f3d4 ("md: fix stopping sync thread") remove
MD_RECOVERY_FROZEN from __md_stop_writes() and doesn't realize that
dm-raid relies on __md_stop_writes() to frozen sync_thread
indirectly. Fix this problem by adding MD_RECOVERY_FROZEN in
md_stop_writes(), and since stop_sync_thread() is only used for
dm-raid in this case, also move stop_sync_thread() to
md_stop_writes().
2) The flag MD_RECOVERY_FROZEN doesn't mean that sync thread is frozen,
it only prevent new sync_thread to start, and it can't stop the
running sync thread; In order to frozen sync_thread, after seting the
flag, stop_sync_thread() should be used.
3) The flag MD_RECOVERY_FROZEN doesn't mean that writes are stopped, use
it as condition for md_stop_writes() in raid_postsuspend() doesn't
look correct. Consider that reentrant stop_sync_thread() do nothing,
always call md_stop_writes() in raid_postsuspend().
4) raid_message can set/clear the flag MD_RECOVERY_FROZEN at anytime,
and if MD_RECOVERY_FROZEN is cleared while the array is suspended,
new sync_thread can start unexpected. Fix this by disallow
raid_message() to change sync_thread status during suspend.
Note that after commit f52f5c71f3d4 ("md: fix stopping sync thread"), the
test shell/lvconvert-raid-reshape.sh start to hang in stop_sync_thread(),
and with previous fixes, the test won't hang there anymore, however, the
test will still fail and complain that ext4 is corrupted. And with this
patch, the test won't hang due to stop_sync_thread() or fail due to ext4
is corrupted anymore. However, there is still a deadlock related to
dm-raid456 that will be fixed in following patches.

Fix this problem by adding MD_RECOVERY_FROZEN in\n md_stop_writes(), and since stop_sync_thread() is only used for\n dm-raid in this case, also move stop_sync_thread() to\n md_stop_writes().\n2) The flag MD_RECOVERY_FROZEN doesn\u0027t mean that sync thread is frozen,\n it only prevent new sync_thread to start, and it can\u0027t stop the\n running sync thread; In order to frozen sync_thread, after seting the\n flag, stop_sync_thread() should be used.\n3) The flag MD_RECOVERY_FROZEN doesn\u0027t mean that writes are stopped, use\n it as condition for md_stop_writes() in raid_postsuspend() doesn\u0027t\n look correct. Consider that reentrant stop_sync_thread() do nothing,\n always call md_stop_writes() in raid_postsuspend().\n4) raid_message can set/clear the flag MD_RECOVERY_FROZEN at anytime,\n and if MD_RECOVERY_FROZEN is cleared while the array is suspended,\n new sync_thread can start unexpected. Fix this by disallow\n raid_message() to change sync_thread status during suspend.\n\nNote that after commit f52f5c71f3d4 (\"md: fix stopping sync thread\"), the\ntest shell/lvconvert-raid-reshape.sh start to hang in stop_sync_thread(),\nand with previous fixes, the test won\u0027t hang there anymore, however, the\ntest will still fail and complain that ext4 is corrupted. And with this\npatch, the test won\u0027t hang due to stop_sync_thread() or fail due to ext4\nis corrupted anymore. However, there is still a deadlock related to\ndm-raid456 that will be fixed in following patches."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcm80211: handle pmk_op allocation failure
The kzalloc() in brcmf_pmksa_v3_op() will return null if the
physical memory has run out. As a result, if we dereference
the null value, the null pointer dereference bug will happen.
Return -ENOMEM from brcmf_pmksa_v3_op() if kzalloc() fails
for pmk_op.

handler may end up writing to the invalid memory and cause crashes.
Add a check to trans->tx_buf before using it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: Fix a memory leak in nf_tables_updchain
If nft_netdev_register_hooks() fails, the memory associated with
nft_stats is not freed, causing a memory leak.
This patch fixes it by moving nft_stats_alloc() down after
nft_netdev_register_hooks() succeeds.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: tcpm: fix double-free issue in tcpm_port_unregister_pd()
When unregister pd capabilitie in tcpm, KASAN will capture below double
-free issue. The root cause is the same capabilitiy will be kfreed twice,
the first time is kfreed by pd_capabilities_release() and the second time
is explicitly kfreed by tcpm_port_unregister_pd().

Summary
In the Linux kernel, the following vulnerability has been resolved:
xen/evtchn: avoid WARN() when unbinding an event channel
When unbinding a user event channel, the related handler might be
called a last time in case the kernel was built with
CONFIG_DEBUG_SHIRQ. This might cause a WARN() in the handler.
Avoid that by adding an "unbinding" flag to struct user_event which
will short circuit the handler.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: check/clear fast rx for non-4addr sta VLAN changes
When moving a station out of a VLAN and deleting the VLAN afterwards, the
fast_rx entry still holds a pointer to the VLAN's netdev, which can cause
use-after-free bugs. Fix this by immediately calling ieee80211_check_fast_rx
after the VLAN change.

"value": "AV:A - The stale `fast_rx-\u003edev` is dereferenced in the 802.11 receive fast path (`ieee80211_rx_8023`) when processing a data frame from the affected station, so the attacker must be an associated WiFi client within radio range of the AP. This is link-local 802.11 reachability, not routable network reach, hence Adjacent.\nAC:L - Once the station has been moved out of a VLAN that is subsequently deleted, every subsequent data frame the attacker transmits deterministically dereferences the freed netdev \u2014 there is no race to win and no memory layout the attacker cannot influence. In a hostapd dynamic-VLAN deployment the attacker induces the move itself by reauthenticating into a different RADIUS-assigned VLAN, and can repeat the sequence at will.\nPR:L - `ieee80211_check_fast_rx` only installs a `fast_rx` entry for a station with `WLAN_STA_AUTHORIZED` and a CCMP/GCMP PTK, so the attacker must be an authenticated, authorized client of the WLAN. That is an ordinary low-privileged network user, not an administrator.\nUI:N - No victim action is needed \u2014 the VLAN reassignment and teardown are performed automatically by hostapd in response to the attacker\u0027s own (re)authentication, and the attacker\u0027s own transmitted frames trigger the dereference.\nS:U - The use-after-free corrupts kernel memory and is exploited within the kernel\u0027s own security authority on the AP; there is no hypervisor, IOMMU, or sandbox boundary crossed.\nC:H - The freed `struct net_device` is read for `-\u003etstats`, `-\u003edev_addr` and `-\u003end_net`, and the skb is delivered into the stack using that stale pointer, so a groomed reclaim yields controlled kernel reads and misdirected traffic delivery; if the slot is reused by a live netdev, the station\u0027s frames leak into a different VLAN, defeating the segmentation the VLAN exists to enforce.\nI:H - `dev_sw_netstats_rx_add(fast_rx-\u003edev, skb-\u003elen)` reads a per-CPU pointer out of the freed object and writes `rx_bytes += skb-\u003elen` (attacker-chosen length) plus `rx_packets++` through it, giving a repeatable, attacker-influenced arbitrary-increment write primitive; combined with the UAF read this is exploitable for control-flow hijacking, and the stale `dev` also permits frame injection into the wrong VLAN.\nA:H - Dereferencing a freed `net_device` from RX softirq context \u2014 including an indirect write through a dangling `-\u003etstats` and passing the freed device to `eth_type_trans`/`netif_receive_skb` \u2014 reliably oopses or panics the access point kernel on the first frame after VLAN teardown."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ARM: ep93xx: Add terminator to gpiod_lookup_table
Without the terminator, if a con_id is passed to gpio_find() that
does not exist in the lookup table the function will not stop looping
correctly, and eventually cause an oops.

Summary
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Drop oob_skb ref before purging queue in GC.
syzbot reported another task hung in __unix_gc(). [0]
The current while loop assumes that all of the left candidates
have oob_skb and calling kfree_skb(oob_skb) releases the remaining
candidates.
However, I missed a case that oob_skb has self-referencing fd and
another fd and the latter sk is placed before the former in the
candidate list. Then, the while loop never proceeds, resulting
the task hung.
__unix_gc() has the same loop just before purging the collected skb,
so we can call kfree_skb(oob_skb) there and let __skb_queue_purge()
release all inflight sockets.

Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: lpspi: Avoid potential use-after-free in probe()
fsl_lpspi_probe() is allocating/disposing memory manually with
spi_alloc_host()/spi_alloc_target(), but uses
devm_spi_register_controller(). In case of error after the latter call the
memory will be explicitly freed in the probe function by
spi_controller_put() call, but used afterwards by "devm" management outside
probe() (spi_unregister_controller() <- devm_spi_unregister() below).
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000070

Summary
In the Linux kernel, the following vulnerability has been resolved:
vfio/pci: Lock external INTx masking ops
Mask operations through config space changes to DisINTx may race INTx
configuration changes via ioctl. Create wrappers that add locking for
paths outside of the core interrupt code.
In particular, irq_type is updated holding igate, therefore testing
is_intx() requires holding igate. For example clearing DisINTx from
config space can otherwise race changes of the interrupt configuration.
This aligns interfaces which may trigger the INTx eventfd into two
camps, one side serialized by igate and the other only enabled while
INTx is configured. A subsequent patch introduces synchronization for
the latter flows.

There is no network-reachable path to `vfio_pci_intx_mask()`/`vfio_pci_intx_unmask()`.\nAC:L - The attacker owns both sides of the race \u2014 one thread loops on DisINTx config writes while another loops on SET_IRQS enable/disable on the same fd \u2014 and can retry indefinitely in preemptible process context on separate cores. `CONFIG_VFIO_PCI_INTX` is `def_bool y if !S390` and INTx is the default vfio-pci interrupt mode, so no unusual configuration is needed.\nPR:L - Only an open VFIO device fd is required; IOMMU-backed VFIO enforces no capability check at all (`CAP_SYS_RAWIO` gates only no-IOMMU mode, `CAP_IPC_LOCK` only mlock accounting), and `/dev/vfio/*` is routinely granted to unprivileged users running QEMU, DPDK/SPDK, or device-mapped containers. No root or `CAP_SYS_ADMIN` is needed.\nUI:N - The attacking process performs every step itself \u2014 spawning two threads that concurrently write DisINTx and issue SET_IRQS on its own file descriptor. No victim action of any kind is involved.\nS:U - Both the vulnerable code and the corrupted memory reside in the host kernel, and the bug is a missing mutex rather than an IOMMU/DMA boundary bypass. This is standard local user-to-kernel privilege escalation within a single security authority.\nC:H - The freed `vfio_pci_irq_ctx` is read after `kfree()`, including its `trigger` pointer which is then dereferenced by `eventfd_signal()`; regrooming the `kmalloc-cg-64` slab turns this into an attacker-controlled pointer read. Per UAF guidance this yields arbitrary kernel memory disclosure.\nI:H - `ctx-\u003emasked = (ret \u003e 0)` writes into the already-freed slab object, and `eventfd_signal()` on a groomed stale pointer performs `ctx-\u003ecount += n` plus `wake_up_locked_poll()`, walking an attacker-shaped wait queue and invoking `curr-\u003efunc()` \u2014 an arbitrary function call giving control-flow hijack.\nA:H - The use-after-free on both `vfio_pci_irq_ctx` and `eventfd_ctx` readily oopses the kernel, and `enable_irq()` racing `free_irq()` produces unbalanced-enable `WARN`s and IRQ disable-depth corruption that can wedge a shared INTx line for other devices."

Summary
In the Linux kernel, the following vulnerability has been resolved:
mac802154: fix llsec key resources release in mac802154_llsec_key_del
mac802154_llsec_key_del() can free resources of a key directly without
following the RCU rules for waiting before the end of a grace period. This
may lead to use-after-free in case llsec_lookup_key() is traversing the
list of keys in parallel with a key deletion:
refcount_t: addition on 0; use-after-free.

Handle the proper resource release in the RCU callback function
mac802154_llsec_key_del_rcu().
Note that if llsec_lookup_key() finds a key, it gets a refcount via
llsec_key_get() and locally copies key id from key_entry (which is a
list element). So it's safe to call llsec_key_put() and free the list
entry after the RCU grace period elapses.

Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: compress: fix to cover normal cluster write with cp_rwsem
When we overwrite compressed cluster w/ normal cluster, we should
not unlock cp_rwsem during f2fs_write_raw_pages(), otherwise data
will be corrupted if partial blocks were persisted before CP & SPOR,
due to cluster metadata wasn't updated atomically.

No network protocol handler is involved.\nAC:L - The attacker controls both sides of the race: one thread overwrites a compressed cluster with incompressible data to enter f2fs_write_raw_pages(), while another thread repeatedly calls the unprivileged syncfs(2), which takes cp_rwsem for write in the window the writer drops it between pages. No condition outside attacker influence is needed to create the inconsistent on-disk cluster state.\nPR:L - Only an unprivileged local account with write access to a file on the f2fs mount is required; f2fs_setflags_common() permits any file owner to set F2FS_COMPR_FL via FS_IOC_SETFLAGS, and compress_extension= mount options enable it automatically. No capability check exists on the write, writeback, or syncfs paths.\nUI:N - The attacker performs every step itself \u2014 creating the compressed file, overwriting the cluster, and forcing checkpoints. On Android and embedded devices the f2fs volume is already mounted at boot, so no victim action is needed.\nS:U - The corruption is confined to the f2fs filesystem and kernel managing it; no security authority boundary such as a VM, hypervisor, or IOMMU domain is crossed.\nC:H - Non-atomic cluster conversion corrupts dnode block addresses together with i_compr_blocks and total_valid_block_count, so blocks can become cross-linked \u2014 an attacker-controlled file ends up referencing blocks the allocator has reassigned to another user\u0027s file, exposing their contents on read. Half-converted clusters also cause stale compressed blocks to be decompressed into the attacker\u0027s page cache.\nI:H - This is fundamentally an integrity bug: the commit states data will be corrupted because cluster metadata is not updated atomically, and the resulting inconsistent dnode blkaddrs, i_blocks, and total_valid_block_count are persistent on-disk filesystem corruption that requires fsck. Cross-linked blocks additionally let the attacker overwrite data belonging to other files.\nA:H - The corrupted cluster makes f2fs_sanity_check_cluster()/__f2fs_cluster_blocks() return -EFSCORRUPTED and set SBI_NEED_FSCK, and f2fs_handle_error() can force the filesystem read-only or panic the kernel under errors=panic. On an embedded, automotive, or Android device whose rootfs/userdata is f2fs, the corrupted volume renders the system unbootable until repaired."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ll_temac: platform_get_resource replaced by wrong function
The function platform_get_resource was replaced with
devm_platform_ioremap_resource_byname and is called using 0 as name.
This eventually ends up in platform_get_resource_byname in the call
stack, where it causes a null pointer in strcmp.
if (type == resource_type(r) && !strcmp(r->name, name))
It should have been replaced with devm_platform_ioremap_resource.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btrtl: fix out of bounds memory access
The problem is detected by KASAN.
btrtl driver uses private hci data to store 'struct btrealtek_data'.
If btrtl driver is used with btusb, then memory for private hci data
is allocated in btusb. But no private data is allocated after hci_dev,
when btrtl is used with hci_h5.
This commit adds memory allocation for hci_h5 case.

No network or adjacent-network data reaches the vulnerable code, and the UART-attached controller is a permanently soldered on-board device rather than a hot-plugged one.\nAC:L - The overflow is unconditional and fully deterministic \u2014 `sizeof_priv` is zero for every RTL H5 device, so every single `btrtl_initialize()`/`btrtl_download_firmware()` run writes past the end of the `hci_dev` allocation with no race, no timing window, and no memory grooming required. It reproduces on the first attempt on every affected system, as the reported KASAN splat from a stock PinePhone boot shows.\nPR:L - An unprivileged local session user on the affected phone/tablet/laptop class can re-trigger the write at will, because `h5_btrtl_resume()` performs a `device_reprobe()` on RTL8723BS parts and a suspend/resume cycle is permitted to active local sessions by default logind/polkit policy, re-running the full setup path. The write also fires with zero privileges during the automatic boot-time probe; the root/`CAP_NET_ADMIN`-gated `HCIDEVUP` ioctl is only one of several trigger routes, not a required one.\nUI:N - The out-of-bounds write executes in a kernel workqueue during automatic device probe and power-on, with no administrator or victim action of any kind. The suspend/resume re-trigger is initiated by the attacker\u0027s own process.\nS:U - The corruption is confined to the kernel slab of the same host and is exploited by, and against, the kernel\u0027s own security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - `btrtl_dmp_hdr()` reads the out-of-bounds `rtl_dump.controller` and `rtl_dump.driver_name` fields back as pointers and `snprintf(\"%s\", ...)`s them into a devcoredump buffer that userspace can read from `/sys/class/devcoredump/`; when that region overlaps a neighbouring slab object whose contents have since changed, this becomes a read of an attacker-influenceable kernel pointer and disclosure of arbitrary kernel memory. The out-of-bounds region also exposes adjacent heap contents to the driver\u0027s own logic (`btrealtek_test_flag`, firmware-version reporting).\nI:H - This is a confirmed slab out-of-bounds write (KASAN \"Write of size 8\") of up to 32 bytes \u2014 two kernel `.rodata` pointers, a firmware-derived `u32`, and a `set_bit()` \u2014 immediately past the `hci_dev` allocation, at a fixed and predictable offset. Depending on kernel version, architecture, and config (`sizeof(struct hci_dev)` relative to the kmalloc bucket, particularly on the 32-bit ARM boards that use this exact driver), those bytes land in the head of the adjacent heap object, giving a repeatable heap-overflow primitive that can be groomed by controlling what occupies the neighbouring slot.\nA:H - Corrupting the first bytes of a neighbouring kmalloc object, and later dereferencing pointers read back out of bounds in `btrtl_dmp_hdr()`, readily produces a kernel oops or panic; the access is repeated on every probe, resume, and device open. On builds with KASAN or arm64 MTE (shipped in production on some Android devices), the very first occurrence is a fatal report/panic, and `panic_on_warn`/`panic_on_oops` hardened embedded and automotive builds turn it into an immediate full system outage."

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/efistub: Call mixed mode boot services on the firmware's stack
Normally, the EFI stub calls into the EFI boot services using the stack
that was live when the stub was entered. According to the UEFI spec,
this stack needs to be at least 128k in size - this might seem large but
all asynchronous processing and event handling in EFI runs from the same
stack and so quite a lot of space may be used in practice.
In mixed mode, the situation is a bit different: the bootloader calls
the 32-bit EFI stub entry point, which calls the decompressor's 32-bit
entry point, where the boot stack is set up, using a fixed allocation
of 16k. This stack is still in use when the EFI stub is started in
64-bit mode, and so all calls back into the EFI firmware will be using
the decompressor's limited boot stack.
Due to the placement of the boot stack right after the boot heap, any
stack overruns have gone unnoticed. However, commit
5c4feadb0011983b ("x86/decompressor: Move global symbol references to C code")
moved the definition of the boot heap into C code, and now the boot
stack is placed right at the base of BSS, where any overruns will
corrupt the end of the .data section.
While it would be possible to work around this by increasing the size of
the boot stack, doing so would affect all x86 systems, and mixed mode
systems are a tiny (and shrinking) fraction of the x86 installed base.
So instead, record the firmware stack pointer value when entering from
the 32-bit firmware, and switch to this stack every time a EFI boot
service call is made.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: processor_idle: Fix memory leak in acpi_processor_power_exit()
After unregistering the CPU idle device, the memory associated with
it is not freed, leading to a memory leak:
unreferenced object 0xffff896282f6c000 (size 1024):
comm "swapper/0", pid 1, jiffies 4294893170
hex dump (first 32 bytes):

Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/hfi1: Fix a memleak in init_credit_return
When dma_alloc_coherent fails to allocate dd->cr_base[i].va,
init_credit_return should deallocate dd->cr_base and
dd->cr_base[i] that allocated before. Or those resources
would be never freed and a memleak is triggered.

Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to avoid use-after-free issue in f2fs_filemap_fault
syzbot reports a f2fs bug as below:
BUG: KASAN: slab-use-after-free in f2fs_filemap_fault+0xd1/0x2c0 fs/f2fs/file.c:49

The root cause is: in f2fs_filemap_fault(), vmf->vma may be not alive after
filemap_fault(), so it may cause use-after-free issue when accessing
vmf->vma->vm_flags in trace_f2fs_filemap_fault(). So it needs to keep vm_flags
in separated temporary variable for tracepoint use.

"value": "AV:L - The vulnerability is triggered through page faults on a memory mapping of a local f2fs file, requiring the attacker to execute code on the system (mmap plus a concurrent munmap thread). There is no remote or adjacent-network path into f2fs_filemap_fault().\nAC:L - The attacker controls both sides of the race \u2014 one thread faults on an evicted page (forced via MADV_DONTNEED/POSIX_FADV_DONTNEED so do_sync_mmap_readahead must drop the fault lock and block on I/O) while a sibling thread munmaps the VMA \u2014 giving a wide, deterministic window that syzkaller reproduced.\nPR:L - Only an ordinary unprivileged local account is needed: no capability, ioctl gate, or admin operation is involved, just creating a file, mmapping it, and faulting. On Android and embedded devices f2fs is already the mounted data filesystem, so any app or user reaches this path directly.\nUI:N - The attacker uses its own file on an already-mounted f2fs volume and drives both the fault and the munmap itself. No victim action such as mounting an image or opening a file is required.\nS:U - The dangling dereference and any resulting disclosure or crash stay entirely within the kernel\u0027s own security authority on the affected host. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free read of a freed vm_area_struct whose contents the attacker can groom by spraying the dedicated, easily-controlled vm_area_cachep, and the stale value is exported into the kernel trace buffer via trace_f2fs_filemap_fault (the f2fs event group is enabled in real deployments such as Android/Perfetto tracing), disclosing freed kernel heap contents including pointers.\nI:N - The defect is purely a stale load \u2014 the fix merely hoists the vm_flags read before filemap_fault() \u2014 and nothing is written to the freed object or anywhere out of bounds. The read value is only passed to a tracepoint and influences no kernel decision or control flow, so no integrity primitive exists.\nA:H - Reading a freed vm_area_struct can fault and oops the kernel \u2014 a KFENCE-sampled VMA (KFENCE ships enabled on Android and distro kernels) leaves its page unmapped after free, and DEBUG_PAGEALLOC/KASAN builds panic outright, with panic_on_oops turning this into a full system crash. The race is repeatable indefinitely by an unprivileged process, so the crash can be driven reliably."

Summary
In the Linux kernel, the following vulnerability has been resolved:
hwrng: core - Fix page fault dead lock on mmap-ed hwrng
There is a dead-lock in the hwrng device read path. This triggers
when the user reads from /dev/hwrng into memory also mmap-ed from
/dev/hwrng. The resulting page fault triggers a recursive read
which then dead-locks.
Fix this by using a stack buffer when calling copy_to_user.

Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix NULL pointer dereference in f2fs_submit_page_write()
BUG: kernel NULL pointer dereference, address: 0000000000000014
RIP: 0010:f2fs_submit_page_write+0x6cf/0x780 [f2fs]
Call Trace:

...
It is possible that other threads have added this fio to io->bio
and submitted the io->bio before entering f2fs_submit_page_write().
At this point io->bio = NULL.
If is_end_zone_blkaddr(sbi, fio->new_blkaddr) of this fio is true,
then an NULL pointer dereference error occurs at bio_get(io->bio).
The original code for determining zone end was after "out:",
which would have missed some fio who is zone end. I've moved
this code before "skip:" to make sure it's done for each fio.

Summary
In the Linux kernel, the following vulnerability has been resolved:
pci_iounmap(): Fix MMIO mapping leak
The #ifdef ARCH_HAS_GENERIC_IOPORT_MAP accidentally also guards iounmap(),
which means MMIO mappings are leaked.
Move the guard so we call iounmap() for MMIO mappings.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: sis: Error out if pixclock equals zero
The userspace program could pass any values to the driver through
ioctl() interface. If the driver doesn't check the value of pixclock,
it may cause divide-by-zero error.
In sisfb_check_var(), var->pixclock is used as a divisor to caculate
drate before it is checked against zero. Fix this by checking it
at the beginning.
This is similar to CVE-2022-3061 in i740fb which was fixed by
commit 15cf0b8.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm-integrity: fix a memory leak when rechecking the data
Memory for the "checksums" pointer will leak if the data is rechecked
after checksum failure (because the associated kfree won't happen due
to 'goto skip_io').
Fix this by freeing the checksums memory before recheck, and just use
the "checksum_onstack" memory for storing checksum during recheck.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ubifs: Set page uptodate in the correct place
Page cache reads are lockless, so setting the freshly allocated page
uptodate before we've overwritten it with the data it's supposed to have
in it will allow a simultaneous reader to see old data. Move the call
to SetPageUptodate into ubifs_write_end(), which is after we copied the
new data into the page.

Summary
In the Linux kernel, the following vulnerability has been resolved:
hv_netvsc: Register VF in netvsc_probe if NET_DEVICE_REGISTER missed
If hv_netvsc driver is unloaded and reloaded, the NET_DEVICE_REGISTER
handler cannot perform VF register successfully as the register call
is received before netvsc_probe is finished. This is because we
register register_netdevice_notifier() very early( even before
vmbus_driver_register()).
To fix this, we try to register each such matching VF( if it is visible
as a netdevice) at the end of netvsc_probe.

In the Linux kernel, the following vulnerability has been resolved:
wifi: wilc1000: fix RCU usage in connect path
With lockdep enabled, calls to the connect function from cfg802.11 layer
lead to the following warning:
=============================
WARNING: suspicious RCU usage

This warning is emitted because in the connect path, when trying to parse
target BSS parameters, we dereference a RCU pointer whithout being in RCU
critical section.
Fix RCU dereference usage by moving it to a RCU read critical section. To
avoid wrapping the whole wilc_parse_join_bss_param under the critical
section, just use the critical section to copy ies data

Exploitation therefore requires only WiFi radio-range adjacency, matching the \"WiFi frame injection = Adjacent\" classification.\nAC:L - The attacker creates and controls both sides of the race \u2014 deauth injection forces wpa_supplicant to re-issue connect while a continuous beacon/probe-response flood churns bss-\u003eies and issues kfree_rcu() \u2014 and the sequence can be retried indefinitely at high rate until the grace period lands inside the unprotected window.\nPR:N - The attacker needs no account, credentials, or network authentication on the target; the privileged NL80211_CMD_CONNECT is issued by the device\u0027s own supplicant as normal auto-reconnect behaviour, which the attacker merely induces from the air.\nUI:N - Reconnection after an injected deauth (and at boot/roam) is performed automatically by wpa_supplicant/NetworkManager with no human involvement.\nS:U - The use-after-free is confined to kernel memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free read of a kernel heap object whose `int len` field then bounds subsequent IE scans, yielding an attacker-influenced out-of-bounds read; the recovered bytes are written into the join parameters sent to firmware and reflected in the association exchange, providing a kernel-memory disclosure channel.\nI:H - Use-after-free with attacker-groomed slab contents lets the attacker dictate the parsed offsets and the resulting join parameters (mode_802_11i, rsn_cap, p_suites, rates, NoA) programmed into the device, and UAF conditions are generally leverageable toward stronger corruption primitives.\nA:H - Parsing freed memory with a bogus/negative `ies-\u003elen` makes cfg80211_find_ie scan far outside the object, producing an oops or panic on unmapped memory, and the attacker can repeat the deauth/reconnect cycle to retrigger the crash at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
riscv: Sparse-Memory/vmemmap out-of-bounds fix
Offset vmemmap so that the first page of vmemmap will be mapped
to the first page of physical memory in order to ensure that
vmemmap’s bounds will be respected during
pfn_to_page()/page_to_pfn() operations.
The conversion macros will produce correct SV39/48/57 addresses
for every possible/valid DRAM_BASE inside the physical memory limits.

"value": "AV:L - The defective `vmemmap` conversion is core arch/MM code exercised through ordinary local syscalls (page faults, mmap, read/write, fork, GUP/DMA setup); it is not reachable as a distinct remote protocol surface. Exploitation therefore requires local execution on the affected RISC-V system.\nAC:L - On an affected RISC-V deployment the out-of-bounds `pfn_to_page()`/`page_to_pfn()` result is deterministic \u2014 no race, no memory-layout guessing, no timing window \u2014 and any unprivileged memory operation reaches it reliably. Per CVSS 3.1 the vulnerable configuration is assumed, and nothing extra beyond the attacker\u0027s control must hold.\nPR:L - No capability, namespace, or admin check guards `pfn_to_page()`/`page_to_pfn()`; a plain unprivileged user process touching pages, mapping memory, or issuing I/O drives the miscomputed conversion. Only a basic local account is needed.\nUI:N - No victim action, mount, or file open is required \u2014 the corrupted address computation is hit by the attacker\u0027s own ordinary memory operations.\nS:U - The out-of-bounds accesses stay within kernel virtual memory (vmemmap spilling into the adjacent vmalloc region); no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `struct page` accesses land outside the vmemmap region in the vmalloc area holding VMAP_STACK kernel stacks and module data, and `page_to_pfn()` returns wrong PFNs so the wrong physical pages are mapped to userspace or DMA\u0027d \u2014 yielding disclosure of arbitrary kernel and other-process memory.\nI:H - The same aliasing gives an out-of-bounds *write*: refcount/flag/mapping updates to `struct page` overwrite vmalloc-region kernel data, and wrong PFNs cause the wrong physical pages to be written, a memory-corruption primitive usable for control-flow hijacking.\nA:H - Overlapping the struct page array with vmalloc allocations and kernel stacks reliably produces oopses, BUG_ONs, and full kernel panics on the affected platform."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/ipv6: avoid possible UAF in ip6_route_mpath_notify()
syzbot found another use-after-free in ip6_route_mpath_notify() [1]
Commit f7225172f25a ("net/ipv6: prevent use after free in
ip6_route_mpath_notify") was not able to fix the root cause.
We need to defer the fib6_info_release() calls after
ip6_route_mpath_notify(), in the cleanup phase.

There is no remote packet-processing path into ip6_route_multipath_add().\nAC:L - The attacker creates both sides of the condition: they drop the last reference themselves and can widen the window arbitrarily by supplying many nexthops, by setting RTA_EXPIRES=0 so the non-rtnl gc softirq reaps the route, and by lowering net.ipv6.route.gc_interval inside their own netns, with unlimited retries. syzbot reproduced it, confirming reliable triggerability.\nPR:L - rtnetlink_rcv_msg() only requires netlink_net_capable(skb, CAP_NET_ADMIN), which is evaluated against the network namespace\u0027s user namespace, so any unprivileged local user obtains it with `unshare -Urn`. Multipath ECMP routes are addable in that namespace using RTNH_F_ONLINK gateways, which bypasses gateway reachability validation.\nUI:N - The entire sequence is performed by the attacker\u0027s own process in a single netlink transaction; no victim action, mount, or other interaction is needed.\nS:U - The use-after-free corrupts kernel heap memory and is exploited within the same kernel security authority; no VM, IOMMU, or hypervisor boundary is crossed.\nC:H - rt6_fill_node() reads the freed kmalloc-512 fib6_info and copies its contents into an RTM_NEWROUTE netlink message returned to the attacker\u0027s socket, including dereferencing pointers taken from freed memory such as rt-\u003efib6_metrics (passed to rtnetlink_put_metrics()), rt-\u003efib6_table, and rt-\u003efib6_nh. Reclaiming the freed slot with controlled data turns this into an arbitrary kernel-memory read leaked directly to userspace.\nI:H - This is a use-after-free on a 512-byte kmalloc object that an unprivileged attacker can spray and reclaim, after which the kernel dereferences attacker-controlled pointers and performs a list_for_each_entry_safe() walk over the freed fib6_siblings list head. That yields controlled pointer traversal and corruption suitable for privilege escalation.\nA:H - The KASAN slab-use-after-free in rt6_fill_node() causes an oops/panic when the freed object is unmapped, poisoned, or reclaimed with invalid pointers, and it can be triggered repeatedly to reliably crash the kernel."

Summary
In the Linux kernel, the following vulnerability has been resolved:
cpumap: Zero-initialise xdp_rxq_info struct before running XDP program
When running an XDP program that is attached to a cpumap entry, we don't
initialise the xdp_rxq_info data structure being used in the xdp_buff
that backs the XDP program invocation. Tobias noticed that this leads to
random values being returned as the xdp_md->rx_queue_index value for XDP
programs running in a cpumap.
This means we're basically returning the contents of the uninitialised
memory, which is bad. Fix this by zero-initialising the rxq data
structure before running the XDP program.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rtnetlink: fix error logic of IFLA_BRIDGE_FLAGS writing back
In the commit d73ef2d69c0d ("rtnetlink: let rtnl_bridge_setlink checks
IFLA_BRIDGE_MODE length"), an adjustment was made to the old loop logic
in the function `rtnl_bridge_setlink` to enable the loop to also check
the length of the IFLA_BRIDGE_MODE attribute. However, this adjustment
removed the `break` statement and led to an error logic of the flags
writing back at the end of this function.
if (have_flags)
memcpy(nla_data(attr), &flags, sizeof(flags));
// attr should point to IFLA_BRIDGE_FLAGS NLA !!!
Before the mentioned commit, the `attr` is granted to be IFLA_BRIDGE_FLAGS.
However, this is not necessarily true fow now as the updated loop will let
the attr point to the last NLA, even an invalid NLA which could cause
overflow writes.
This patch introduces a new variable `br_flag` to save the NLA pointer
that points to IFLA_BRIDGE_FLAGS and uses it to resolve the mentioned
error logic.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-fc: do not wait in vain when unloading module
The module exit path has race between deleting all controllers and
freeing 'left over IDs'. To prevent double free a synchronization
between nvme_delete_ctrl and ida_destroy has been added by the initial
commit.
There is some logic around trying to prevent from hanging forever in
wait_for_completion, though it does not handling all cases. E.g.
blktests is able to reproduce the situation where the module unload
hangs forever.
If we completely rely on the cleanup code executed from the
nvme_delete_ctrl path, all IDs will be freed eventually. This makes
calling ida_destroy unnecessary. We only have to ensure that all
nvme_delete_ctrl code has been executed before we leave
nvme_fc_exit_module. This is done by flushing the nvme_delete_wq
workqueue.
While at it, remove the unused nvme_fc_wq workqueue too.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: bridge: confirm multicast packets before passing them up the stack
conntrack nf_confirm logic cannot handle cloned skbs referencing
the same nf_conn entry, which will happen for multicast (broadcast)
frames on bridges.
Example:
macvlan0
|
br0
/ \
ethX ethY
ethX (or Y) receives a L2 multicast or broadcast packet containing
an IP packet, flow is not yet in conntrack table.
1. skb passes through bridge and fake-ip (br_netfilter)Prerouting.
-> skb->_nfct now references a unconfirmed entry
2. skb is broad/mcast packet. bridge now passes clones out on each bridge
interface.
3. skb gets passed up the stack.
4. In macvlan case, macvlan driver retains clone(s) of the mcast skb
and schedules a work queue to send them out on the lower devices.
The clone skb->_nfct is not a copy, it is the same entry as the
original skb. The macvlan rx handler then returns RX_HANDLER_PASS.
5. Normal conntrack hooks (in NF_INET_LOCAL_IN) confirm the orig skb.
The Macvlan broadcast worker and normal confirm path will race.
This race will not happen if step 2 already confirmed a clone. In that
case later steps perform skb_clone() with skb->_nfct already confirmed (in
hash table). This works fine.
But such confirmation won't happen when eb/ip/nftables rules dropped the
packets before they reached the nf_confirm step in postrouting.
Pablo points out that nf_conntrack_bridge doesn't allow use of stateful
nat, so we can safely discard the nf_conn entry and let inet call
conntrack again.
This doesn't work for bridge netfilter: skb could have a nat
transformation. Also bridge nf prevents re-invocation of inet prerouting
via 'sabotage_in' hook.
Work around this problem by explicit confirmation of the entry at LOCAL_IN
time, before upper layer has a chance to clone the unconfirmed entry.
The downside is that this disables NAT and conntrack helpers.
Alternative fix would be to add locking to all code parts that deal with
unconfirmed packets, but even if that could be done in a sane way this
opens up other problems, for example:
-m physdev --physdev-out eth0 -j SNAT --snat-to 1.2.3.4
-m physdev --physdev-out eth1 -j SNAT --snat-to 1.2.3.5
For multicast case, only one of such conflicting mappings will be
created, conntrack only handles 1:1 NAT mappings.
Users should set create a setup that explicitly marks such traffic
NOTRACK (conntrack bypass) to avoid this, but we cannot auto-bypass
them, ruleset might have accept rules for untracked traffic already,
so user-visible behaviour would change.

Also bridge nf prevents re-invocation of inet prerouting\nvia \u0027sabotage_in\u0027 hook.\n\nWork around this problem by explicit confirmation of the entry at LOCAL_IN\ntime, before upper layer has a chance to clone the unconfirmed entry.\n\nThe downside is that this disables NAT and conntrack helpers.\n\nAlternative fix would be to add locking to all code parts that deal with\nunconfirmed packets, but even if that could be done in a sane way this\nopens up other problems, for example:\n\n-m physdev --physdev-out eth0 -j SNAT --snat-to 1.2.3.4\n-m physdev --physdev-out eth1 -j SNAT --snat-to 1.2.3.5\n\nFor multicast case, only one of such conflicting mappings will be\ncreated, conntrack only handles 1:1 NAT mappings.\n\nUsers should set create a setup that explicitly marks such traffic\nNOTRACK (conntrack bypass) to avoid this, but we cannot auto-bypass\nthem, ruleset might have accept rules for untracked traffic already,\nso user-visible behaviour would change."

"value": "AV:A - The trigger is a received link-layer broadcast/multicast IP frame arriving on a bridge port (the hook only runs when `skb-\u003epkt_type != PACKET_HOST`), so the attacker must be in the same L2 broadcast domain \u2014 a LAN neighbor, a co-tenant VM/container on the same bridge, or a guest behind a tap port. Broadcast frames cannot be routed, which bounds this to adjacent rather than full network reach.\nAC:L - One attacker-sent broadcast/multicast packet is itself what forks into the two racing skbs (original up the stack vs. `macvlan_broadcast_enqueue` clone deferred to `bc_work` on another CPU), so the attacker controls both sides of the race and can flood packets to hit it repeatedly and reliably. macvlan/tap-over-bridge with br_netfilter and conntrack is a mainstream Docker/libvirt/unraid configuration, not a rare one.\nPR:N - The entire path is inbound packet processing in softirq and a kernel workqueue \u2014 no syscall, no socket, no credentials, and no capability check is crossed. An unauthenticated host on the segment simply emits broadcast/multicast traffic.\nUI:N - The bridge, macvlan and conntrack hooks process the attacker\u0027s frames automatically on receipt; no administrator or user action is needed at any point.\nS:U - The vulnerable code and the corrupted objects (`nf_conn`, `ct-\u003eext`, the conntrack and nf_nat_bysource hash tables) all live in the host kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed by the defect itself.\nC:H - Concurrent unlocked `krealloc()` of `ct-\u003eext` and duplicate `hlist_add_head_rcu()` of `ct-\u003enat_bysource` yield a double-free/use-after-free on slab objects whose contents the attacker can influence by shaping subsequent traffic, giving a path to reading reclaimed kernel memory. Per kernel scoring guidance, UAF-class corruption is High.\nI:H - The same double-free and duplicate list-node insertions provide a write primitive into freed/reallocated slab memory and into RCU hash chains, and the non-atomic `ct-\u003estatus` read-modify-write plus conflicting NAT mappings additionally corrupt firewall/NAT state. Memory corruption of this class is scored High for integrity.\nA:H - The in-the-wild manifestation is a `WARN_ON_ONCE()` splat in `__nf_conntrack_confirm()` \u2014 an oops-class event that panics outright under `panic_on_warn` \u2014 and the underlying list corruption and refcount imbalance lead to hlist corruption and premature `nf_conn` free, i.e. kernel crashes, all repeatedly inducible by continued broadcast traffic."

This is because when the device goes offline, we obtain the hisi_hba
semaphore and send the ABORT_DEV command to the device. However, the
internal abort timed out due to the 2 bit ECC error and triggers automatic
dump. In addition, since the hisi_hba semaphore has been obtained, the dump
cannot be executed and the controller cannot be reset.
Therefore, the deadlocks occur on the following circular dependencies

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:
x86/fpu: Stop relying on userspace for info to fault in xsave buffer
Before this change, the expected size of the user space buffer was
taken from fx_sw->xstate_size. fx_sw->xstate_size can be changed
from user-space, so it is possible construct a sigreturn frame where:
* fx_sw->xstate_size is smaller than the size required by valid bits in
fx_sw->xfeatures.
* user-space unmaps parts of the sigrame fpu buffer so that not all of
the buffer required by xrstor is accessible.
In this case, xrstor tries to restore and accesses the unmapped area
which results in a fault. But fault_in_readable succeeds because buf +
fx_sw->xstate_size is within the still mapped area, so it goes back and
tries xrstor again. It will spin in this loop forever.
Instead, fault in the maximum size which can be touched by XRSTOR (taken
from fpstate->user_size).

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: target: core: Add TMF to tmr_list handling
An abort that is responded to by iSCSI itself is added to tmr_list but does
not go to target core. A LUN_RESET that goes through tmr_list takes a
refcounter on the abort and waits for completion. However, the abort will
be never complete because it was not started in target core.
Unable to locate ITT: 0x05000000 on CID: 0
Unable to locate RefTaskTag: 0x05000000 on CID: 0.

The same path is exported to other network fabrics (isert/RDMA, cxgbit).\nAC:L - The attacker fully controls both halves: an ABORT_TASK with a bogus RefTaskTag and out-of-window RefCmdSN parks a stale entry on dev_tmr_list, and an immediate-flagged LUN_RESET (which bypasses CmdSN sequencing) then walks that list. Using an out-of-order CmdSN keeps the stale entry alive indefinitely, so no race window has to be won.\nPR:N - Only an iSCSI session in full-feature phase is needed, and iSCSI login is unauthenticated in the standard SAN deployment (CHAP disabled, or generate_node_acls=1 demo mode) where the only \"credential\" is a plaintext IQN string that is discoverable via SendTargets and trivially spoofed.\nUI:N - The attacker sends two TMF PDUs on their own connection; no action by any administrator, initiator host, or local user is required.\nS:U - The deadlock is confined to the kernel\u0027s own target-core subsystem and its worker threads, with no crossing into a different security authority such as a hypervisor or IOMMU boundary.\nC:N - The defect is an unbalanced completion wait on a TMR that never entered target core; no memory is read out of bounds and no kernel data is disclosed to the initiator.\nI:N - Nothing is written out of bounds and no freed object is reused \u2014 the reference count is held too long rather than dropped too early, so there is no corruption or control-flow primitive.\nA:H - The target_tmr_work kworker blocks forever in target_put_cmd_and_wait() and the iSCSI thread loops indefinitely in __transport_wait_for_tasks(), leaving unkillable D-state threads, a permanently pinned lun_ref that prevents LUN/device teardown, and a wedged storage target that only a reboot recovers; the hung-task detector can also panic the box."

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/fpu: Keep xfd_state in sync with MSR_IA32_XFD
Commit 672365477ae8 ("x86/fpu: Update XFD state where required") and
commit 8bf26758ca96 ("x86/fpu: Add XFD state to fpstate") introduced a
per CPU variable xfd_state to keep the MSR_IA32_XFD value cached, in
order to avoid unnecessary writes to the MSR.
On CPU hotplug MSR_IA32_XFD is reset to the init_fpstate.xfd, which
wipes out any stale state. But the per CPU cached xfd value is not
reset, which brings them out of sync.
As a consequence a subsequent xfd_update_state() might fail to update
the MSR which in turn can result in XRSTOR raising a #NM in kernel
space, which crashes the kernel.
To fix this, introduce xfd_set_state() to write xfd_state together
with MSR_IA32_XFD, and use it in all places that set MSR_IA32_XFD.

Summary
In the Linux kernel, the following vulnerability has been resolved:
stmmac: Clear variable when destroying workqueue
Currently when suspending driver and stopping workqueue it is checked whether
workqueue is not NULL and if so, it is destroyed.
Function destroy_workqueue() does drain queue and does clear variable, but
it does not set workqueue variable to NULL. This can cause kernel/module
panic if code attempts to clear workqueue that was not initialized.
This scenario is possible when resuming suspended driver in stmmac_resume(),
because there is no handling for failed stmmac_hw_setup(),
which can fail and return if DMA engine has failed to initialize,
and workqueue is initialized after DMA engine.
Should DMA engine fail to initialize, resume will proceed normally,
but interface won't work and TX queue will eventually timeout,
causing 'Reset adapter' error.
This then does destroy workqueue during reset process.
And since workqueue is initialized after DMA engine and can be skipped,
it will cause kernel/module panic.
To secure against this possible crash, set workqueue variable to NULL when
destroying workqueue.
Log/backtrace from crash goes as follows:

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: core: Fix deadlock in port "disable" sysfs attribute
The show and store callback routines for the "disable" sysfs attribute
file in port.c acquire the device lock for the port's parent hub
device. This can cause problems if another process has locked the hub
to remove it or change its configuration:
Removing the hub or changing its configuration requires the
hub interface to be removed, which requires the port device
to be removed, and device_del() waits until all outstanding
sysfs attribute callbacks for the ports have returned. The
lock can't be released until then.
But the disable_show() or disable_store() routine can't return
until after it has acquired the lock.
The resulting deadlock can be avoided by calling
sysfs_break_active_protection(). This will cause the sysfs core not
to wait for the attribute's callback routine to return, allowing the
removal to proceed. The disadvantage is that after making this call,
there is no guarantee that the hub structure won't be deallocated at
any moment. To prevent this, we have to acquire a reference to it
first by calling hub_get().

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: nl80211: reject iftype change with mesh ID change
It's currently possible to change the mesh ID when the
interface isn't yet in mesh mode, at the same time as
changing it into mesh mode. This leads to an overwrite
of data in the wdev->u union for the interface type it
currently has, causing cfg80211_change_iface() to do
wrong things when switching.
We could probably allow setting an interface to mesh
while setting the mesh ID at the same time by doing a
different order of operations here, but realistically
there's no userspace that's going to do this, so just
disallow changes in iftype when setting mesh ID.

"value": "AV:L - The vulnerability is triggered entirely through local interfaces \u2014 an nl80211 generic-netlink `NL80211_CMD_SET_INTERFACE` message to plant the corrupted length, then a local `SIOCGIWESSID` ioctl or `NL80211_CMD_GET_INTERFACE` to weaponize it. No radio frames or remote peer data are involved.\nAC:L - Exploitation is fully deterministic: a single netlink message containing `NL80211_ATTR_IFTYPE=MESH_POINT`, a \u22655-byte `NL80211_ATTR_MESH_ID`, and `NL80211_ATTR_4ADDR=1` on a down ADHOC interface reliably sets `wdev-\u003eu.ibss.ssid_len` to an attacker-chosen value and returns before the sanitizing memset. There is no race, no memory-layout dependency, and no condition outside the attacker\u0027s control.\nPR:L - `NL80211_CMD_SET_INTERFACE` is gated by `GENL_UNS_ADMIN_PERM`, the user-namespace-aware CAP_NET_ADMIN check, which an unprivileged user obtains via `unshare -Urn`; `mac80211_hwsim`\u0027s radio-creation command is namespace-aware in the same way, giving a wiphy inside that namespace. The weaponizing steps (`SIOCGIWESSID`, `NL80211_CMD_GET_INTERFACE`) require no privileges at all.\nUI:N - The attacker performs every step \u2014 creating/selecting the interface, setting it to ADHOC while down, sending the malformed SET_INTERFACE, and issuing the read. No victim action is required.\nS:U - The type-confused write and the resulting heap overflow stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The corrupted `ibss.ssid_len` (up to 255) causes up to ~223 bytes past the 32-byte SSID buffer to be copied to userspace via `NL80211_ATTR_SSID` and via the `SIOCGIWESSID` `copy_to_user()` from a 32-byte slab object, disclosing adjacent kernel memory including `wdev-\u003elinks[]` heap pointers \u2014 well beyond a \"few bytes\" bounded read.\nI:H - `cfg80211_ibss_wext_giwessid()` performs an unchecked `memcpy` of up to 255 bytes into the 32-byte `kzalloc` buffer allocated by `ioctl_standard_iw_point()`, giving an out-of-bounds slab write of up to 223 bytes with partially attacker-influenced content \u2014 a classic heap-corruption primitive.\nA:H - The out-of-bounds write smashes adjacent kmalloc-32 objects, producing KASAN BUG reports, slab corruption and kernel panics; on mesh-capable wiphys the same bug additionally triggers a `WARN_ONCE` in `check_sdata_in_driver()` via a spurious `drv_leave_ibss()` on a down interface, which panics under `panic_on_warn`."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix potential NULL pointer dereferences in 'dcn10_set_output_transfer_func()'
The 'stream' pointer is used in dcn10_set_output_transfer_func() before
the check if 'stream' is NULL.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn10/dcn10_hwseq.c:1892 dcn10_set_output_transfer_func() warn: variable dereferenced before check 'stream' (see line 1875)

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/vma: Fix UAF on destroy against retire race
Object debugging tools were sporadically reporting illegal attempts to
free a still active i915 VMA object when parking a GT believed to be idle.
[161.359441] ODEBUG: free active (active state 0) object: ffff88811643b958 object type: i915_active hint: __i915_vma_active+0x0/0x50 [i915]
[161.360082] WARNING: CPU: 5 PID: 276 at lib/debugobjects.c:514 debug_print_object+0x80/0xb0
...
[161.360304] CPU: 5 PID: 276 Comm: kworker/5:2 Not tainted 6.5.0-rc1-CI_DRM_13375-g003f860e5577+ #1
[161.360314] Hardware name: Intel Corporation Rocket Lake Client Platform/RocketLake S UDIMM 6L RVP, BIOS RKLSFWI1.R00.3173.A03.2204210138 04/21/2022
[161.360322] Workqueue: i915-unordered __intel_wakeref_put_work [i915]
[161.360592] RIP: 0010:debug_print_object+0x80/0xb0
...
[161.361347] debug_object_free+0xeb/0x110
[161.361362] i915_active_fini+0x14/0x130 [i915]

[161.363129] __gt_park+0x121/0x230 [i915]
[161.363515] ____intel_wakeref_put_last+0x1f/0x70 [i915]
That has been tracked down to be happening when another thread is
deactivating the VMA inside __active_retire() helper, after the VMA's
active counter has been already decremented to 0, but before deactivation
of the VMA's object is reported to the object debugging tool.
We could prevent from that race by serializing i915_active_fini() with
__active_retire() via ref->tree_lock, but that wouldn't stop the VMA from
being used, e.g. from __i915_vma_retire() called at the end of
__active_retire(), after that VMA has been already freed by a concurrent
i915_vma_destroy() on return from the i915_active_fini(). Then, we should
rather fix the issue at the VMA level, not in i915_active.
Since __i915_vma_parked() is called from __gt_park() on last put of the
GT's wakeref, the issue could be addressed by holding the GT wakeref long
enough for __active_retire() to complete before that wakeref is released
and the GT parked.
I believe the issue was introduced by commit d93939730347 ("drm/i915:
Remove the vma refcount") which moved a call to i915_active_fini() from
a dropped i915_vma_release(), called on last put of the removed VMA kref,
to i915_vma_parked() processing path called on last put of a GT wakeref.
However, its visibility to the object debugging tool was suppressed by a
bug in i915_active that was fixed two weeks later with commit e92eb246feb9
("drm/i915/active: Fix missing debug object activation").
A VMA associated with a request doesn't acquire a GT wakeref by itself.
Instead, it depends on a wakeref held directly by the request's active
intel_context for a GT associated with its VM, and indirectly on that
intel_context's engine wakeref if the engine belongs to the same GT as the
VMA's VM. Those wakerefs are released asynchronously to VMA deactivation.
Fix the issue by getting a wakeref for the VMA's GT when activating it,
and putting that wakeref only after the VMA is deactivated. However,
exclude global GTT from that processing path, otherwise the GPU never goes
idle. Since __i915_vma_retire() may be called from atomic contexts, use
async variant of wakeref put. Also, to avoid circular locking dependency,
take care of acquiring the wakeref before VM mutex when both are needed.
v7: Add inline comments with justifications for:
- using untracked variants of intel_gt_pm_get/put() (Nirmoy),
- using async variant of _put(),
- not getting the wakeref in case of a global GTT,
- always getting the first wakeref outside vm->mutex.
v6: Since __i915_vma_active/retire() callbacks are not serialized, storing
a wakeref tracking handle inside struct i915_vma is not safe, and
there is no other good place for that. Use untracked variants of
intel_gt_pm_get/put_async().
v5: Replace "tile" with "GT" across commit description (Rodrigo),

Those wakerefs are released asynchronously to VMA deactivation.\n\nFix the issue by getting a wakeref for the VMA\u0027s GT when activating it,\nand putting that wakeref only after the VMA is deactivated. However,\nexclude global GTT from that processing path, otherwise the GPU never goes\nidle. Since __i915_vma_retire() may be called from atomic contexts, use\nasync variant of wakeref put. Also, to avoid circular locking dependency,\ntake care of acquiring the wakeref before VM mutex when both are needed.\n\nv7: Add inline comments with justifications for:\n - using untracked variants of intel_gt_pm_get/put() (Nirmoy),\n - using async variant of _put(),\n - not getting the wakeref in case of a global GTT,\n - always getting the first wakeref outside vm-\u003emutex.\nv6: Since __i915_vma_active/retire() callbacks are not serialized, storing\n a wakeref tracking handle inside struct i915_vma is not safe, and\n there is no other good place for that.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme: fix reconnection fail due to reserved tag allocation
We found a issue on production environment while using NVMe over RDMA,
admin_q reconnect failed forever while remote target and network is ok.
After dig into it, we found it may caused by a ABBA deadlock due to tag
allocation. In my case, the tag was hold by a keep alive request
waiting inside admin_q, as we quiesced admin_q while reset ctrl, so the
request maked as idle and will not process before reset success. As
fabric_q shares tagset with admin_q, while reconnect remote target, we
need a tag for connect command, but the only one reserved tag was held
by keep alive command which waiting inside admin_q. As a result, we
failed to reconnect admin_q forever. In order to fix this issue, I
think we should keep two reserved tags for admin queue.

A remote or on-path attacker against the NVMe/TCP connection (port 4420) can drive the vulnerable path without local access.\nAC:L - The attacker controls the reset side of the race and can force error recovery/reconnect cycles arbitrarily many times (reconnect re-arms the keep-alive timer each round), while the keep-alive period is deterministic at kato/2, so the window can be hit by retry and by timing; the bug was also observed occurring spontaneously in production. Once won, the leaked reserved tag is permanent \u2014 no further conditions are needed.\nPR:N - No credentials on the victim host are required \u2014 the triggering events (TCP FIN/RST, malformed NVMe/TCP PDU, unresponsive target) are handled by `nvme_tcp_state_change()` and the recv path before or independent of any NVMe-level authentication, and NVMe/TCP deployments commonly run with no DH-HMAC-CHAP or TLS at all.\nUI:N - Exploitation requires no action from any user or administrator; an already-established NVMe-oF connection is a system configuration precondition, not victim interaction, and the keep-alive/reset machinery runs autonomously in kernel workqueues.\nS:U - The impact is confined to the kernel and the host\u0027s own storage stack \u2014 no security authority boundary such as a VM, IOMMU, or sandbox is crossed.\nC:N - The defect is a reserved-tag leak causing an ABBA allocation deadlock; no memory is read out of bounds, no freed object is accessed, and no kernel data is disclosed to the attacker.\nI:N - There is no memory corruption, out-of-bounds write, or control-flow primitive \u2014 the only consequence is that a blk-mq tag is never returned, so no attacker-influenced data modification is possible.\nA:H - The admin queue can never reconnect (\"failed to reconnect admin_q forever\"), because the admin tagset is not reallocated on reconnect and the connect command\u0027s reserved tag allocation fails with -EAGAIN indefinitely, producing a permanent loss of the NVMe-oF storage path plus eventual controller deletion (and a hung, unkillable teardown worker blocked on queue freeze) \u2014 total availability loss for storage that is frequently the system\u0027s root or primary data volume."

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme: host: fix double-free of struct nvme_id_ns in ns_update_nuse()
When nvme_identify_ns() fails, it frees the pointer to the struct
nvme_id_ns before it returns. However, ns_update_nuse() calls kfree()
for the pointer even when nvme_identify_ns() fails. This results in
KASAN double-free, which was observed with blktests nvme/045 with
proposed patches [1] on the kernel v6.8-rc7. Fix the double-free by
skipping kfree() when nvme_identify_ns() fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Defer the free of inner map when necessary
When updating or deleting an inner map in map array or map htab, the map
may still be accessed by non-sleepable program or sleepable program.
However bpf_map_fd_put_ptr() decreases the ref-counter of the inner map
directly through bpf_map_put(), if the ref-counter is the last one
(which is true for most cases), the inner map will be freed by
ops->map_free() in a kworker. But for now, most .map_free() callbacks
don't use synchronize_rcu() or its variants to wait for the elapse of a
RCU grace period, so after the invocation of ops->map_free completes,
the bpf program which is accessing the inner map may incur
use-after-free problem.
Fix the free of inner map by invoking bpf_map_free_deferred() after both
one RCU grace period and one tasks trace RCU grace period if the inner
map has been removed from the outer map before. The deferment is
accomplished by using call_rcu() or call_rcu_tasks_trace() when
releasing the last ref-counter of bpf map. The newly-added rcu_head
field in bpf_map shares the same storage space with work field to
reduce the size of bpf_map.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: mtk_eth_soc: fix PPE hanging issue
A patch to resolve an issue was found in MediaTek's GPL-licensed SDK:
In the mtk_ppe_stop() function, the PPE scan mode is not disabled before
disabling the PPE. This can potentially lead to a hang during the process
of disabling the PPE.
Without this patch, the PPE may experience a hang during the reboot test.

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: camcc-sc8280xp: fix terminating of frequency table arrays
The frequency table arrays are supposed to be terminated with an
empty element. Add such entry to the end of the arrays where it
is missing in order to avoid possible out-of-bound access when
the table is traversed by functions like qcom_find_freq() or
qcom_find_freq_floor().
Only compile tested.

This is genuine unintended modification of device state, but it yields no memory-write or control-flow primitive.\nA:H - The unterminated walk can run past the end of the mapped rodata region and fault, producing a kernel oops, and programming a garbage divider/source onto a live camera/CPAS clock can wedge the subsystem\u0027s bus accesses and hang the device.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: veth: clear GRO when clearing XDP even when down
veth sets NETIF_F_GRO automatically when XDP is enabled,
because both features use the same NAPI machinery.
The logic to clear NETIF_F_GRO sits in veth_disable_xdp() which
is called both on ndo_stop and when XDP is turned off.
To avoid the flag from being cleared when the device is brought
down, the clearing is skipped when IFF_UP is not set.
Bringing the device down should indeed not modify its features.
Unfortunately, this means that clearing is also skipped when
XDP is disabled _while_ the device is down. And there's nothing
on the open path to bring the device features back into sync.
IOW if user enables XDP, disables it and then brings the device
up we'll end up with a stray GRO flag set but no NAPI instances.
We don't depend on the GRO flag on the datapath, so the datapath
won't crash. We will crash (or hang), however, next time features
are sync'ed (either by user via ethtool or peer changing its config).
The GRO flag will go away, and veth will try to disable the NAPIs.
But the open path never created them since XDP was off, the GRO flag
was a stray. If NAPI was initialized before we'll hang in napi_disable().
If it never was we'll crash trying to stop uninitialized hrtimer.
Move the GRO flag updates to the XDP enable / disable paths,
instead of mixing them with the ndo_open / ndo_close paths.

However, since the kernel is build optimized, it seems the stack is not
accurate. It appears the issue is related to wfx_set_mfp_ap(). The issue
is obvious in this function: memory allocated by ieee80211_beacon_get()
is never released. Fixing this leak makes kmemleak happy.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Avoid potential use-after-free in hci_error_reset
While handling the HCI_EV_HARDWARE_ERROR event, if the underlying
BT controller is not responding, the GPIO reset mechanism would
free the hci_dev and lead to a use-after-free in hci_error_reset.
Here's the call trace observed on a ChromeOS device with Intel AX201:
queue_work_on+0x3e/0x6c
__hci_cmd_sync_sk+0x2ee/0x4c0 [bluetooth <HASH:3b4a6>]
? init_wait_entry+0x31/0x31
__hci_cmd_sync+0x16/0x20 [bluetooth <HASH:3b4a 6>]
hci_error_reset+0x4f/0xa4 [bluetooth <HASH:3b4a 6>]
process_one_work+0x1d8/0x33f
worker_thread+0x21b/0x373
kthread+0x13a/0x152
? pr_cont_work+0x54/0x54
? kthread_blkcg+0x31/0x31
ret_from_fork+0x1f/0x30
This patch holds the reference count on the hci_dev while processing
a HCI_EV_HARDWARE_ERROR event to avoid potential crash.

This is radio-proximity access, not routable network access.\nAC:L - Once the controller is wedged, the sequence is effectively deterministic: `btintel_hw_error()` blocks for two full `HCI_INIT_TIMEOUT` intervals while `hci_cmd_timeout()` counts to five and fires the GPIO reset, so the race window in which `hci_error_reset` runs against `hci_unregister_dev`/`hci_release_dev` is seconds wide and both sides are driven by the same attacker-induced controller failure. The bug was reproducible enough to be observed in the field on shipping ChromeOS/Intel AX201 hardware.\nPR:N - An over-the-air attacker needs no pairing, bonding, authentication, or any account on the target \u2014 malformed link-layer traffic that faults the controller firmware is processed before any credential check. No host-side privileges are involved at all since the triggering event arrives from the controller.\nUI:N - No victim action is required; the hardware error event, the command timeouts, the GPIO reset and the resulting USB disconnect/unregister all occur automatically inside the kernel once the controller faults.\nS:U - The use-after-free corrupts kernel heap memory within the same security authority as the vulnerable code; no VM, hypervisor, or IOMMU boundary is crossed.\nC:H - `hci_release_dev()` frees `hdev-\u003eworkqueue` (and ultimately `kfree(hdev)`) while `hci_error_reset` is still executing, so `queue_work_on()` reads `wq-\u003eflags` and `wq-\u003ecpu_pwq` out of a freed slab object the attacker can groom by reclaiming it, yielding a kernel-memory read primitive and disclosure of adjacent heap contents and pointers.\nI:H - After the freed `workqueue_struct` is reclaimed with attacker-controlled data, `queue_work_on()` performs a list insertion into the pool worklist derived from that freed memory, giving a controlled write primitive suitable for corrupting adjacent kernel objects and hijacking control flow; the stale `hdev` is likewise written through by the continuing close/open sequence.\nA:H - The confirmed use-after-free reliably oopses or panics the kernel (the reported crash in `queue_work_on` from `hci_error_reset`), and the freed/destroyed workqueue also strands the subsequent `destroy_workqueue(hdev-\u003ereq_workqueue)` drain, permanently wedging the Bluetooth stack."

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: Use device rbtree in iopf reporting path
The existing I/O page fault handler currently locates the PCI device by
calling pci_get_domain_bus_and_slot(). This function searches the list
of all PCI devices until the desired device is found. To improve lookup
efficiency, replace it with device_rbtree_find() to search the device
within the probed device rbtree.
The I/O page fault is initiated by the device, which does not have any
synchronization mechanism with the software to ensure that the device
stays in the probed device tree. Theoretically, a device could be released
by the IOMMU subsystem after device_rbtree_find() and before
iopf_get_dev_fault_param(), which would cause a use-after-free problem.
Add a mutex to synchronize the I/O page fault reporting path and the IOMMU
release device path. This lock doesn't introduce any performance overhead,
as the conflict between I/O page fault reporting and device releasing is
very rare.

There is no network or physical-only requirement.\nAC:L - The attacker can flood the PRQ ring (even provoking PRQ overflow) to keep the racy window continuously executing and retry indefinitely, and in the assigned-device/malicious-endpoint case also controls the removal side via link-down, surprise-removal or AER-triggered teardown. The window is also structurally wide because `device_del()` frees `dev-\u003eiommu` before `pci_destroy_dev()` unlinks the device from the PCI bus list, so `pci_get_domain_bus_and_slot()` keeps returning a device whose `dev-\u003eiommu` is already freed.\nPR:L - Only access to a device that can emit page requests is needed \u2014 an SVA work queue or render node routinely granted to unprivileged users, or guest-side control of a passed-through device. No real root or CAP_SYS_ADMIN in the init namespace is required.\nUI:N - The page request is generated by the attacker-driven device and handled asynchronously in the IOMMU threaded IRQ handler; no victim action is involved.\nS:C - The VT-d driver is the authority that confines DMA-capable devices to their assigned address spaces, and here a device-initiated page request corrupts host kernel memory outside that confinement. In the passthrough deployment this is a guest/device-to-host escape across the IOMMU isolation boundary.\nC:H - The use-after-free reads `param-\u003efault_param` and `fparam-\u003edata` out of a freed kmalloc-96/128 object that an unprivileged process can reallocate with sprayed content, turning the subsequent dereferences into an arbitrary kernel-memory read and disclosure primitive.\nI:H - `mutex_lock(\u0026param-\u003elock)` writes into the freed object, `list_add_tail(\u0026evt_pending-\u003elist, \u0026fparam-\u003efaults)` gives a write through an attacker-controlled pointer, and `fparam-\u003ehandler(\u0026evt-\u003efault, fparam-\u003edata)` is an indirect call through a function pointer read from freed memory \u2014 a control-flow hijack primitive.\nA:H - Dereferencing the freed `dev_iommu` in the IOMMU threaded IRQ handler oopses or panics the kernel, and a corrupted mutex in that path can hang all subsequent page-fault handling."

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_conntrack_h323: Add protection for bmp length out of range
UBSAN load reports an exception of BRK#5515 SHIFT_ISSUE:Bitwise shifts
that are out of bounds for their data type.
vmlinux get_bitmap(b=75) + 712
<net/netfilter/nf_conntrack_h323_asn1.c:0>
vmlinux decode_seq(bs=0xFFFFFFD008037000, f=0xFFFFFFD008037018, level=134443100) + 1956
<net/netfilter/nf_conntrack_h323_asn1.c:592>
vmlinux decode_choice(base=0xFFFFFFD0080370F0, level=23843636) + 1216
<net/netfilter/nf_conntrack_h323_asn1.c:814>
vmlinux decode_seq(f=0xFFFFFFD0080371A8, level=134443500) + 812
<net/netfilter/nf_conntrack_h323_asn1.c:576>
vmlinux decode_choice(base=0xFFFFFFD008037280, level=0) + 1216
<net/netfilter/nf_conntrack_h323_asn1.c:814>
vmlinux DecodeRasMessage() + 304
<net/netfilter/nf_conntrack_h323_asn1.c:833>
vmlinux ras_help() + 684
<net/netfilter/nf_conntrack_h323_main.c:1728>
vmlinux nf_confirm() + 188
<net/netfilter/nf_conntrack_proto.c:137>
Due to abnormal data in skb->data, the extension bitmap length
exceeds 32 when decoding ras message then uses the length to make
a shift operation. It will change into negative after several loop.
UBSAN load could detect a negative shift as an undefined behaviour
and reports exception.
So we add the protection to avoid the length exceeding 32. Or else
it will return out of range error and stop decoding.

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: mmcc-msm8974: fix terminating of frequency table arrays
The frequency table arrays are supposed to be terminated with an
empty element. Add such entry to the end of the arrays where it
is missing in order to avoid possible out-of-bound access when
the table is traversed by functions like qcom_find_freq() or
qcom_find_freq_floor().
Only compile tested.

The adjacent .data contents are fixed at build and registration time, so the outcome is reproducible on every attempt.\nPR:L - An unprivileged local user with ordinary access to the display or camera/video device nodes (standard for the video/render groups on the Android and embedded MSM8974/MSM8226 devices this driver targets) can drive rate requests through mdss_axi_clk and the *_ocmemnoc branches, which carry CLK_SET_RATE_PARENT into the two unterminated tables. No root or capability is needed.\nUI:N - The clock-rate request is issued by the attacker\u0027s own ioctl/modeset activity on the display or video device; no victim action or separate user is involved.\nS:U - The out-of-bounds read, the leaked data, and the resulting misprogrammed clock all remain within the kernel\u0027s own security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The loop is an unbounded out-of-bounds read with no length check, walking adjacent .data that contains live kernel pointers (parent_map, freq_tbl, clkr.regmap, clkr.hw.core) in the neighbouring struct clk_rcg2. The OOB entry\u0027s freq is propagated to req-\u003erate and surfaces to userspace via clk_round_rate() and the clk_rate debugfs node, disclosing kernel .data and defeating KASLR.\nI:L - The out-of-bounds src, pre_div, m and n values are written into the RCG CFG/M/N/D hardware registers, reprogramming the MMSS AXI / OCMEM NoC bus clock with an unintended source and divider \u2014 a real modification of system state. The values are not attacker-controlled and there is no out-of-bounds write into kernel memory, so this falls short of a full integrity compromise.\nA:H - The global out-of-bounds read triggers a KASAN global-OOB report (fatal under panic_on_warn) and the unterminated walk can run past the end of the section, while programming a garbage source select and divider into the multimedia bus clock can hang the MMSS bus and lock up the SoC."

Summary
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: fix a memleak in gss_import_v2_context
The ctx->mech_used.data allocated by kmemdup is not freed in neither
gss_import_v2_context nor it only caller gss_krb5_import_sec_context,
which frees ctx on error.
Thus, this patch reform the last call of gss_import_v2_context to the
gss_krb5_import_ctx_v2, preventing the memleak while keepping the return
formation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vfio/platform: Create persistent IRQ handlers
The vfio-platform SET_IRQS ioctl currently allows loopback triggering of
an interrupt before a signaling eventfd has been configured by the user,
which thereby allows a NULL pointer dereference.
Rather than register the IRQ relative to a valid trigger, register all
IRQs in a disabled state in the device open path. This allows mask
operations on the IRQ to nest within the overall enable state governed
by a valid eventfd signal. This decouples @masked, protected by the
@locked spinlock from @trigger, protected via the @igate mutex.
In doing so, it's guaranteed that changes to @trigger cannot race the
IRQ handlers because the IRQ handler is synchronously disabled before
modifying the trigger, and loopback triggering of the IRQ via ioctl is
safe due to serialization with trigger changes via igate.
For compatibility, request_irq() failures are maintained to be local to
the SET_IRQS ioctl rather than a fatal error in the open device path.
This allows, for example, a userspace driver with polling mode support
to continue to work regardless of moving the request_irq() call site.
This necessarily blocks all SET_IRQS access to the failed index.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-tpg: fix some memleaks in tpg_alloc
In tpg_alloc, resources should be deallocated in each and every
error-handling paths, since they are allocated in for statements.
Otherwise there would be memleaks because tpg_free is called only when
tpg_alloc return 0.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dpll: fix dpll_xa_ref_*_del() for multiple registrations
Currently, if there are multiple registrations of the same pin on the
same dpll device, following warnings are observed:
WARNING: CPU: 5 PID: 2212 at drivers/dpll/dpll_core.c:143 dpll_xa_ref_pin_del.isra.0+0x21e/0x230
WARNING: CPU: 5 PID: 2212 at drivers/dpll/dpll_core.c:223 __dpll_pin_unregister+0x2b3/0x2c0
The problem is, that in both dpll_xa_ref_dpll_del() and
dpll_xa_ref_pin_del() registration is only removed from list in case the
reference count drops to zero. That is wrong, the registration has to
be removed always.
To fix this, remove the registration from the list and free
it unconditionally, instead of doing it only when the ref reference
counter reaches zero.

Summary
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: fix some memleaks in gssx_dec_option_array
The creds and oa->data need to be freed in the error-handling paths after
their allocation. So this patch add these deallocations in the
corresponding paths.

Although the malformed/short XDR reply is delivered by the local gssproxy daemon, the attacker\u0027s reach to the vulnerable function is purely over the network.\nAC:L - The attacker can invoke the upcall path an unlimited number of times pre-authentication, and each invocation pins 256 KB of receive pages plus the in-token pages, letting the attacker themselves create the slab/memory-pressure condition under which the `kzalloc(struct svc_cred)` fails and the dangling-pointer path is taken (trivially so for a memcg-limited/containerized nfsd). The attacker also influences gssproxy reply size via principal name length and group-list size, driving the `-ENOSPC` decode-error paths, so the required conditions are attacker-inducible rather than beyond their control.\nPR:N - `svcauth_gss_proxy_init()` is reached from `svcauth_gss_proc_init()` on the very first leg of the GSS handshake, before any Kerberos credential is validated \u2014 the upcall is performed even for a garbage input token. No account, key, or prior authentication on the NFS server is needed.\nUI:N - The path is triggered entirely by an inbound RPC from the attacker; no administrator or user of the target system needs to mount, click, or open anything.\nS:U - The corrupted objects (`gssx_option`, `svc_cred`) and the resulting heap damage are all inside the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - With `oa-\u003ecount == 1` and `oa-\u003edata` dangling, `gssp_accept_sec_context_upcall()` reads `res.options.data[0].value` out of a freed kmalloc-32 object and then dereferences the pointer it finds there into `data-\u003ecreds`, so freed/reallocated kernel memory contents are consumed and can populate `cr_uid`/`cr_gid`/`cr_principal` \u2014 a use-after-free read that both discloses kernel memory and can determine the identity the NFS client is authenticated as.\nI:H - The same path yields `kfree()` of a pointer taken from freed memory plus a double free of `oa-\u003edata`, and later `free_svc_cred()` performs `put_group_info()`, `gss_mech_put()` and further `kfree()`s on attacker-groomable pointers \u2014 an arbitrary-free and arbitrary-refcount-decrement primitive that is a well-established route to controlled heap corruption and control-flow hijack.\nA:H - The double free trips SLUB\u0027s free-object detection (`BUG`/panic, fatal with `panic_on_oops` on the appliance and NAS deployments where nfsd+gssproxy is typical), and the NULL `oa-\u003edata` variant of the same incoherent `oa-\u003ecount` faults immediately in the caller. The unbounded, remotely repeatable leakage of the decoder\u0027s allocations additionally drives the server toward OOM."

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix double free of anonymous device after snapshot creation failure
When creating a snapshot we may do a double free of an anonymous device
in case there's an error committing the transaction. The second free may
result in freeing an anonymous device number that was allocated by some
other subsystem in the kernel or another btrfs filesystem.
The steps that lead to this:
1) At ioctl.c:create_snapshot() we allocate an anonymous device number
and assign it to pending_snapshot->anon_dev;
2) Then we call btrfs_commit_transaction() and end up at
transaction.c:create_pending_snapshot();
3) There we call btrfs_get_new_fs_root() and pass it the anonymous device
number stored in pending_snapshot->anon_dev;
4) btrfs_get_new_fs_root() frees that anonymous device number because
btrfs_lookup_fs_root() returned a root - someone else did a lookup
of the new root already, which could some task doing backref walking;
5) After that some error happens in the transaction commit path, and at
ioctl.c:create_snapshot() we jump to the 'fail' label, and after
that we free again the same anonymous device number, which in the
meanwhile may have been reallocated somewhere else, because
pending_snapshot->anon_dev still has the same value as in step 1.

Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring: Fix release of pinned pages when __io_uaddr_map fails
Looking at the error path of __io_uaddr_map, if we fail after pinning
the pages for any reasons, ret will be set to -EINVAL and the error
handler won't properly release the pinned pages.
I didn't manage to trigger it without forcing a failure, but it can
happen in real life when memory is heavily fragmented.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: udc: remove warning when queue disabled ep
It is possible trigger below warning message from mass storage function,
WARNING: CPU: 6 PID: 3839 at drivers/usb/gadget/udc/core.c:294 usb_ep_queue+0x7c/0x104
pc : usb_ep_queue+0x7c/0x104
lr : fsg_main_thread+0x494/0x1b3c
Root cause is mass storage function try to queue request from main thread,
but other thread may already disable ep when function disable.
As there is no function failure in the driver, in order to avoid effort
to fix warning, change WARN_ON_ONCE() in usb_ep_queue() to pr_debug().

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI/PM: Drain runtime-idle callbacks before driver removal
A race condition between the .runtime_idle() callback and the .remove()
callback in the rtsx_pcr PCI driver leads to a kernel crash due to an
unhandled page fault [1].
The problem is that rtsx_pci_runtime_idle() is not expected to be running
after pm_runtime_get_sync() has been called, but the latter doesn't really
guarantee that. It only guarantees that the suspend and resume callbacks
will not be running when it returns.
However, if a .runtime_idle() callback is already running when
pm_runtime_get_sync() is called, the latter will notice that the runtime PM
status of the device is RPM_ACTIVE and it will return right away without
waiting for the former to complete. In fact, it cannot wait for
.runtime_idle() to complete because it may be called from that callback (it
arguably does not make much sense to do that, but it is not strictly
prohibited).
Thus in general, whoever is providing a .runtime_idle() callback needs
to protect it from running in parallel with whatever code runs after
pm_runtime_get_sync(). [Note that .runtime_idle() will not start after
pm_runtime_get_sync() has returned, but it may continue running then if it
has started earlier.]
One way to address that race condition is to call pm_runtime_barrier()
after pm_runtime_get_sync() (not before it, because a nonzero value of the
runtime PM usage counter is necessary to prevent runtime PM callbacks from
being invoked) to wait for the .runtime_idle() callback to complete should
it be running at that point. A suitable place for doing that is in
pci_device_remove() which calls pm_runtime_get_sync() before removing the
driver, so it may as well call pm_runtime_barrier() subsequently, which
will prevent the race in question from occurring, not just in the rtsx_pcr
driver, but in any PCI drivers providing .runtime_idle() callbacks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: amd: Fix memory leak in amd_sof_acp_probe()
Driver uses kasprintf() to initialize fw_{code,data}_bin members of
struct acp_dev_data, but kfree() is never called to deallocate the
memory, which results in a memory leak.
Fix the issue by switching to devm_kasprintf(). Additionally, ensure the
allocation was successful by checking the pointer validity.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: don't set the MFP flag for the GTK
The firmware doesn't need the MFP flag for the GTK, it can even make the
firmware crash. in case the AP is configured with: group cipher TKIP and
MFPC. We would send the GTK with cipher = TKIP and MFP which is of course
not possible.

"value": "AV:A - The trigger is entirely controlled by the 802.11 peer (AP) via its advertised RSN group cipher and MFPC capability, consumed during association/4-way handshake by a Wi-Fi client. This requires the attacker to be within radio range on the same wireless segment, i.e. adjacent network.\nAC:L - An attacker operating an AP (including an evil twin on a network whose PSK is known or shared, such as caf\u00e9/office/guest Wi-Fi) fully controls the required configuration \u2014 group cipher TKIP with MFPC \u2014 and the crash follows deterministically on GTK installation, with no race or memory-layout dependency. The other precondition (PMF negotiated, so `sta-\u003emfp` is set) is the default on modern supplicants.\nPR:N - The attacker needs no account, capability, or any privilege on the victim system; they merely configure the AP the client associates with. No local access or kernel-side authorization is involved on the target.\nUI:N - wpa_supplicant/NetworkManager auto-reconnect to a known SSID after a deauth means the association and GTK installation happen with no user action. The vulnerable code runs as part of normal automated connection setup.\nS:U - The consequences are confined to the Wi-Fi device and the kernel driver managing it \u2014 the same security authority as the vulnerable component. No VM, IOMMU, or sandbox boundary is crossed.\nC:N - The defect is an incorrect flag bit in a firmware command; there is no out-of-bounds read, uninitialized data disclosure, or leak of kernel memory to the attacker.\nI:L - The group key is installed in firmware with the wrong protection semantics \u2014 flagged as en/decrypting management frames when a non-iGTK group key must not be \u2014 so management-frame protection state for the GTK is incorrect, which any group member could attempt to abuse for forged \"protected\" broadcast management frames. This is bounded, not arbitrary, modification.\nA:H - The malformed TKIP+MFP key command asserts the firmware, producing a SW-error dump and a full NIC restart with loss of wireless connectivity, and can be re-triggered on every reconnect attempt for a persistent denial of service. Firmware re-init after such asserts can also fail outright, leaving the adapter unusable until reboot."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7921e: fix use-after-free in free_irq()
From commit a304e1b82808 ("[PATCH] Debug shared irqs"), there is a test
to make sure the shared irq handler should be able to handle the unexpected
event after deregistration. For this case, let's apply MT76_REMOVED flag to
indicate the device was removed and do not run into the resource access
anymore.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: nxp: imx8-isi: Check whether crossbar pad is non-NULL before access
When translating source to sink streams in the crossbar subdev, the
driver tries to locate the remote subdev connected to the sink pad. The
remote pad may be NULL, if userspace tries to enable a stream that ends
at an unconnected crossbar sink. When that occurs, the driver
dereferences the NULL pad, leading to a crash.
Prevent the crash by checking if the pad is NULL before using it, and
return an error if it is.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: fsl-qdma: init irq after reg initialization
Initialize the qDMA irqs after the registers are configured so that
interrupts that may have been pending from a primary kernel don't get
processed by the irq handler before it is ready to and cause panic with
the following trace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: Use separate handlers for interrupts
For PF to AF interrupt vector and VF to AF vector same
interrupt handler is registered which is causing race condition.
When two interrupts are raised to two CPUs at same time
then two cores serve same event corrupting the data.

No packet-processing path leads here, so exploitation requires local access to the host or to a passed-through VF.\nAC:L - The attacker drives both sides of the race himself \u2014 one thread spamming PF\u2192AF mailbox messages (e.g. unprivileged `ethtool -a`, which issues `cgx_cfg_pause_frm`) while another spams the VF\u2192AF doorbell on a separate MSI-X vector affined to a different CPU. No condition outside the attacker\u0027s control is required, and the race can be retried indefinitely at high rate.\nPR:L - Generating AF mailbox traffic needs only an ordinary local account \u2014 several octeontx2 ethtool GET operations (`get_pauseparam`, `get_fecparam`) send mailbox messages with no capability check \u2014 or possession of an SR-IOV VF exposed to a container/guest, which can write the mailbox trigger register directly. No root or CAP_NET_ADMIN in the initial namespace is required.\nUI:N - The attacker triggers both interrupt vectors entirely on his own by issuing ethtool/netdev requests and mailbox doorbell writes. No administrator or victim action is needed at any point.\nS:U - The corrupted mailbox bookkeeping and the resulting out-of-bounds accesses are all inside the host kernel, the same security authority as the vulnerable RVU AF driver. No hypervisor, IOMMU, or sandbox boundary is crossed by the corruption itself.\nC:H - When the concurrently-bumped `num_msgs` extends the loop in `__rvu_mbox_handler()` past the valid message list, `msg` is taken from unvalidated memory and `offset` is advanced by an unchecked 16-bit `next_msgoff`, producing out-of-bounds reads outside the 64 KB `ioremap_wc()` mailbox window whose contents are then acted on and echoed back in mailbox responses \u2014 an unbounded kernel read primitive.\nI:H - The same overrun performs an unconditional write (`msg-\u003epcifunc \u0026= ...; msg-\u003epcifunc |= ...`) at the attacker-influenced out-of-bounds offset before any signature validation, and the duplicate work-queue dispatch re-executes already-completed AF resource commands such as LF free/detach against released state, corrupting the admin function\u0027s resource tables.\nA:H - Duplicate processing of resource-teardown mailbox messages and out-of-range accesses to the ioremapped mailbox region readily oops the kernel, while the mutually-cleared interrupt bits drop mailbox events and wedge the AF\u2194PF/VF control plane, taking down all NIX/NPA networking on the SoC."

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: hisilicon: hi3559a: Fix an erroneous devm_kfree()
'p_clk' is an array allocated just before the for loop for all clk that
need to be registered.
It is incremented at each loop iteration.
If a clk_register() call fails, 'p_clk' may point to something different
from what should be freed.
The best we can do, is to avoid this wrong release of memory.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/mm: Disallow vsyscall page read for copy_from_kernel_nofault()
When trying to use copy_from_kernel_nofault() to read vsyscall page
through a bpf program, the following oops was reported:
BUG: unable to handle page fault for address: ffffffffff600000
#PF: supervisor read access in kernel mode
#PF: error_code(0x0000) - not-present page

......
---[ end trace 0000000000000000 ]---
The oops is triggered when:
1) A bpf program uses bpf_probe_read_kernel() to read from the vsyscall
page and invokes copy_from_kernel_nofault() which in turn calls
__get_user_asm().
2) Because the vsyscall page address is not readable from kernel space,
a page fault exception is triggered accordingly.
3) handle_page_fault() considers the vsyscall page address as a user
space address instead of a kernel space address. This results in the
fix-up setup by bpf not being applied and a page_fault_oops() is invoked
due to SMAP.
Considering handle_page_fault() has already considered the vsyscall page
address as a userspace address, fix the problem by disallowing vsyscall
page read for copy_from_kernel_nofault().

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: gcc-ipq9574: fix terminating of frequency table arrays
The frequency table arrays are supposed to be terminated with an
empty element. Add such entry to the end of the arrays where it
is missing in order to avoid possible out-of-bound access when
the table is traversed by functions like qcom_find_freq() or
qcom_find_freq_floor().
Only compile tested.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm-crypt: don't modify the data when using authenticated encryption
It was said that authenticated encryption could produce invalid tag when
the data that is being encrypted is modified [1]. So, fix this problem by
copying the data into the clone bio first and then encrypt them inside the
clone bio.
This may reduce performance, but it is needed to prevent the user from
corrupting the device by writing data with O_DIRECT and modifying them at
the same time.

No remote peer can modify an in-flight kernel source buffer, so there is no network or adjacent path.\nAC:L - The attacker owns both sides of the race \u2014 one thread submits the `O_DIRECT` write while another rewrites the same buffer in a tight loop \u2014 and can repeat it across many pages until the AEAD reads inconsistent plaintext; public PoCs exist for this exact class (Mikulas Patocka\u0027s `blk-auth-modify` testcases cited by the sibling dm-verity/dm-integrity recheck fixes).

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm: bridge/panel: Cleanup connector on bridge detach
If we don't call drm_connector_cleanup() manually in
panel_bridge_detach(), the connector will be cleaned up with the other
DRM objects in the call to drm_mode_config_cleanup(). However, since our
drm_connector is devm-allocated, by the time drm_mode_config_cleanup()
will be called, our connector will be long gone. Therefore, the
connector must be cleaned up when the bridge is detached to avoid
use-after-free conditions.
v2: Cleanup connector only if it was created
v3: Add FIXME
v4: (Use connector->dev) directly in if() block

There is no remote or adjacent-network path to amdgpu_vm_bo_clear_mappings().\nAC:L - A single ioctl with an attacker-chosen va_address/map_size pair deterministically overflows the u64 bounds check and produces a reversed range; no race, no memory-layout dependency, no timing window. The attacker fully controls both operands of the overflowing arithmetic.\nPR:L - The ioctl is DRM_AUTH|DRM_RENDER_ALLOW, so any process able to open the render node can reach it \u2014 that includes ordinary desktop users (ACL/render group), GPU-enabled containers, and sandboxed renderer processes on Android/ChromeOS. No CAP_SYS_ADMIN, no DRM_MASTER, no root required.\nUI:N - The attacker performs the entire sequence (create BO, map it, issue the crafted CLEAR) within their own process and its own amdgpu VM. No victim action or cooperation is needed.\nS:U - The corruption is confined to the kernel\u0027s own amdgpu VM structures and GPU page tables managed by the same kernel security authority. No hypervisor, IOMMU, or sandbox boundary is crossed by the flaw itself.\nC:H - The malformed split leaves overlapping GPU VA mappings with inconsistent BO offsets in vm-\u003eva, desynchronizing the driver\u0027s mapping state from the programmed PTEs, and the unvalidated range removes the max_pfn guard that keeps page-table walks in bounds. Per kernel scoring guidance, memory/page-table corruption that can be leveraged to expose memory outside the buffer object is High.\nI:H - Overlapping mappings are inserted into the VM interval tree, a mapping with start \u003e last is queued for PTE clearing, and PRT refcounts are skewed \u2014 all of which cause GPU page tables to be programmed inconsistently with the driver\u0027s view. This memory-corruption class is scored High for integrity.\nA:H - The reversed range makes amdgpu_vm_update_range() compute (last - start + 1) * AMDGPU_GPU_PAGE_SIZE as a ~2^64 underflow, driving amdgpu_vm_ptes_update()/amdgpu_vm_pt_alloc() over an ~2^60-page range while holding the VM eviction and reservation locks. The result is unbounded page-table allocation, memory exhaustion, and a soft-lockup/hang of the GPU and system."

Summary
In the Linux kernel, the following vulnerability has been resolved:
afs: Increase buffer size in afs_update_volume_status()
The max length of volume->vid value is 20 characters.
So increase idbuf[] size up to 24 to avoid overflow.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
[DH: Actually, it's 20 + NUL, so increase it to 24 and use snprintf()]

AFS VL traffic is unauthenticated rxrpc over UDP, so a rogue cell server or an on-path response spoofer reaches this code across the network.\nAC:H - Overflowing `idbuf[16]` requires `volume-\u003evid` to exceed 10 decimal digits, but the on-wire `volumeId[]` field is `__be32` (fs/afs/afs_vl.h:123) and is the sole source of `volume-\u003evid`, capping it at `4294967295`. The wire-format width is a hard constraint entirely beyond the attacker\u0027s control, so no attainable input triggers the write.\nPR:N - The attacker is the VL server (or a network entity spoofing its unauthenticated replies) and holds no account, credential, or capability on the target host. No local privilege on the victim is consumed anywhere along the `afs_select_fileserver` \u2192 `afs_check_volume_status` \u2192 `afs_update_volume_status` path.\nUI:N - On a configured AFS client `/afs` is already mounted at boot, and the volume-status refresh fires from routine background revalidation and from server-supplied VMOVED/VNOVOL responses without any victim action. The attacker drives the update himself via the fileserver\u0027s abort codes.\nS:U - Any corruption is confined to the AFS client\u0027s own kernel stack frame within the same kernel security authority. No VM, hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - A stack write past `idbuf` overwrites the adjacent locals in the same frame \u2014 the `new`/`old`/`discard`/`vldb` pointers and `idsz` \u2014 and corrupting `vldb` or `idsz` redirects the subsequent `memcmp`/`memcpy` of the volume name and the `afs_alloc_server_list()` walk, yielding an attacker-influenced kernel read. Per kernel guidance, memory corruption leverageable for disclosure is scored High.\nI:H - This is an out-of-bounds stack write, which per kernel guidance is High: the clobbered pointers are dereferenced and written through immediately afterwards (`memcpy(volume-\u003ename, vldb-\u003ename, AFS_MAXVOLNAME)`, `rcu_assign_pointer(volume-\u003eservers, new)`), giving a path to controlled kernel memory modification and control-flow influence.\nA:H - On any stack-protector kernel the 5-byte overrun smashes the canary and `__stack_chk_fail()` panics the machine; without it, the corrupted `vldb`/`new`/`old` pointers are dereferenced and freed (`kfree(vldb)`, `afs_put_serverlist()`), producing an oops. Either outcome is a full kernel crash."

Summary
In the Linux kernel, the following vulnerability has been resolved:
debugfs: fix wait/cancellation handling during remove
Ben Greear further reports deadlocks during concurrent debugfs
remove while files are being accessed, even though the code in
question now uses debugfs cancellations. Turns out that despite
all the review on the locking, we missed completely that the
logic is wrong: if the refcount hits zero we can finish (and
need not wait for the completion), but if it doesn't we have
to trigger all the cancellations. As written, we can _never_
get into the loop triggering the cancellations. Fix this, and
explain it better while at it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: xhci: Add error handling in xhci_map_urb_for_dma
Currently xhci_map_urb_for_dma() creates a temporary buffer and copies
the SG list to the new linear buffer. But if the kzalloc_node() fails,
then the following sg_pcopy_to_buffer() can lead to crash since it
tries to memcpy to NULL pointer.
So return -ENOMEM if kzalloc returns null pointer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: mcast: remove one synchronize_net() barrier in ipv6_mc_down()
As discussed in the past (commit 2d3916f31891 ("ipv6: fix skb drops
in igmp6_event_query() and igmp6_event_report()")) I think the
synchronize_net() call in ipv6_mc_down() is not needed.
Under load, synchronize_net() can last between 200 usec and 5 ms.
KASAN seems to agree as well.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: phy: fix phy_get_internal_delay accessing an empty array
The phy_get_internal_delay function could try to access to an empty
array in the case that the driver is calling phy_get_internal_delay
without defining delay_values and rx-internal-delay-ps or
tx-internal-delay-ps is defined to 0 in the device-tree.
This will lead to "unable to handle kernel NULL pointer dereference at
virtual address 0". To avoid this kernel oops, the test should be delay
>= 0. As there is already delay < 0 test just before, the test could
only be size == 0.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: dvb-frontends: avoid stack overflow warnings with clang
A previous patch worked around a KASAN issue in stv0367, now a similar
problem showed up with clang:
drivers/media/dvb-frontends/stv0367.c:1222:12: error: stack frame size (3624) exceeds limit (2048) in 'stv0367ter_set_frontend' [-Werror,-Wframe-larger-than]
1214 | static int stv0367ter_set_frontend(struct dvb_frontend *fe)
Rework the stv0367_writereg() function to be simpler and mark both
register access functions as noinline_for_stack so the temporary
i2c_msg structures do not get duplicated on the stack when KASAN_STACK
is enabled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
libbpf: Use OPTS_SET() macro in bpf_xdp_query()
When the feature_flags and xdp_zc_max_segs fields were added to the libbpf
bpf_xdp_query_opts, the code writing them did not use the OPTS_SET() macro.
This causes libbpf to write to those fields unconditionally, which means
that programs compiled against an older version of libbpf (with a smaller
size of the bpf_xdp_query_opts struct) will have its stack corrupted by
libbpf writing out of bounds.
The patch adding the feature_flags field has an early bail out if the
feature_flags field is not part of the opts struct (via the OPTS_HAS)
macro, but the patch adding xdp_zc_max_segs does not. For consistency, this
fix just changes the assignments to both fields to use the OPTS_SET()
macro.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/bridge: adv7511: fix crash on irq during probe
Moved IRQ registration down to end of adv7511_probe().
If an IRQ already is pending during adv7511_probe
(before adv7511_cec_init) then cec_received_msg_ts
could crash using uninitialized data:
Unable to handle kernel read from unreadable memory at virtual address 00000000000003d5
Internal error: Oops: 96000004 [#1] PREEMPT_RT SMP

=====================================================
If the packet type ID field in the Ethernet header is either ETH_P_PRP or
ETH_P_HSR, but it is not followed by an HSR tag, hsr_get_skb_sequence_nr()
reads an invalid value as a sequence number. This causes the above issue.
This patch fixes the issue by returning NULL if the Ethernet header is not
followed by an HSR tag.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: cdns3: fix memory double free when handle zero packet
829 if (request->complete) {
830 spin_unlock(&priv_dev->lock);
831 usb_gadget_giveback_request(&priv_ep->endpoint,
832 request);
833 spin_lock(&priv_dev->lock);
834 }
835
836 if (request->buf == priv_dev->zlp_buf)
837 cdns3_gadget_ep_free_request(&priv_ep->endpoint, request);
Driver append an additional zero packet request when queue a packet, which
length mod max packet size is 0. When transfer complete, run to line 831,
usb_gadget_giveback_request() will free this requestion. 836 condition is
true, so cdns3_gadget_ep_free_request() free this request again.
Log:
[ 1920.140696][ T150] BUG: KFENCE: use-after-free read in cdns3_gadget_giveback+0x134/0x2c0 [cdns3]
[ 1920.140696][ T150]
[ 1920.151837][ T150] Use-after-free read at 0x000000003d1cd10b (in kfence-#36):

[ 1920.164988][ T150] cdns3_transfer_completed+0x438/0x5f8 [cdns3]
Add check at line 829, skip call usb_gadget_giveback_request() if it is
additional zero length packet request. Needn't call
usb_gadget_giveback_request() because it is allocated in this driver.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: wilc1000: prevent use-after-free on vif when cleaning up all interfaces
wilc_netdev_cleanup currently triggers a KASAN warning, which can be
observed on interface registration error path, or simply by
removing the module/unbinding device from driver:

David Mosberger-Tan initial investigation [1] showed that this
use-after-free is due to netdevice unregistration during vif list
traversal. When unregistering a net device, since the needs_free_netdev has
been set to true during registration, the netdevice object is also freed,
and as a consequence, the corresponding vif object too, since it is
attached to it as private netdevice data. The next occurrence of the loop
then tries to access freed vif pointer to the list to move forward in the
list.
Fix this use-after-free thanks to two mechanisms:
- navigate in the list with list_for_each_entry_safe, which allows to
safely modify the list as we go through each element. For each element,
remove it from the list with list_del_rcu
- make sure to wait for RCU grace period end after each vif removal to make
sure it is safe to free the corresponding vif too (through
unregister_netdev)
Since we are in a RCU "modifier" path (not a "reader" path), and because
such path is expected not to be concurrent to any other modifier (we are
using the vif_mutex lock), we do not need to use RCU list API, that's why
we can benefit from list_for_each_entry_safe.

For each element,\n remove it from the list with list_del_rcu\n- make sure to wait for RCU grace period end after each vif removal to make\n sure it is safe to free the corresponding vif too (through\n unregister_netdev)\n\nSince we are in a RCU \"modifier\" path (not a \"reader\" path), and because\nsuch path is expected not to be concurrent to any other modifier (we are\nusing the vif_mutex lock), we do not need to use RCU list API, that\u0027s why\nwe can benefit from list_for_each_entry_safe.\n\n[1] https://lore.kernel.org/linux-wireless/ab077dbe58b1ea5de0a3b2ca21f275a07af967d2.camel@egauge.net/"

Summary
In the Linux kernel, the following vulnerability has been resolved:
aio: Fix null ptr deref in aio_complete() wakeup
list_del_init_careful() needs to be the last access to the wait queue
entry - it effectively unlocks access.
Previously, finish_wait() would see the empty list head and skip taking
the lock, and then we'd return - but the completion path would still
attempt to do the wakeup after the task_struct pointer had been
overwritten.

Exploitation requires the ability to execute code on the target system.\nAC:L - The attacker controls both sides of the race \u2014 a thread blocked in io_getevents() supplies the waiter, and a second thread deterministically drives aio_complete() on another CPU (e.g. IOCB_CMD_POLL armed on a pipe, or O_DIRECT block completions), and the sequence can be retried millions of times per second with CPU pinning. The bug was observed firing in ordinary production workloads, confirming the window is reachable without any condition outside the attacker\u0027s influence.\nPR:L - io_setup/io_submit/io_getevents are unprivileged syscalls with no capability, LSM, or namespace gate on the path through do_io_getevents() \u2192 read_events(); CONFIG_AIO is default y and enabled on virtually all deployments. Any local unprivileged user, including one inside a container, can reach the vulnerable code.\nUI:N - The entire attack is a self-contained sequence of syscalls issued by the attacker\u0027s own threads. No victim action, mount, or file open is needed.\nS:U - The corruption occurs in kernel memory and is exploited by a local user to attack the same kernel; there is no crossing of a VM, IOMMU, or other security-authority boundary. This is a standard kernel local privilege-escalation scope.\nC:H - This is a use-after-return on the waiter\u0027s kernel stack whose stale contents the attacker can groom with a follow-up syscall, and the resulting pointer is dereferenced by try_to_wake_up(), which reads p-\u003e__state, p-\u003eon_rq, p-\u003eon_cpu and task_cpu(p) from attacker-chosen kernel addresses. Per kernel scoring guidance, UAF-class corruption that can be steered into arbitrary kernel reads is High.\nI:H - try_to_wake_up() on the attacker-influenced pointer performs raw_spin_lock_irqsave(\u0026p-\u003epi_lock), WRITE_ONCE(p-\u003e__state, TASK_WAKING) and a runqueue enqueue with linked-list pointer stores, yielding a write primitive at an attacker-selected address, with the scheduler ultimately context-switching into a forged task_struct. That is memory corruption exploitable for control-flow hijack and privilege escalation.\nA:H - The reported and readily reproducible symptom is a NULL/wild pointer dereference in aio_complete()\u0027s wakeup path, producing a kernel oops in interrupt-disabled context. Any unprivileged user can trigger this repeatedly to panic the machine."

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: mmcc-apq8084: fix terminating of frequency table arrays
The frequency table arrays are supposed to be terminated with an
empty element. Add such entry to the end of the arrays where it
is missing in order to avoid possible out-of-bound access when
the table is traversed by functions like qcom_find_freq() or
qcom_find_freq_floor().
Only compile tested.

There is no network-facing path to qcom_find_freq().\nAC:L - The overrun is deterministic: any rate request exceeding the last table entry (466.8 MHz / 320 MHz) walks past the array end every time, with no race to win and no attacker-uncontrollable state. The adjacent .data layout is fixed at build time, so an attacker targeting a known device knows exactly what is read.\nPR:L - An unprivileged local user with access to the camera or display device nodes (routinely granted to normal apps via the media/graphics groups on Android and embedded builds) can drive a rate request into the affected RCGs through the CLK_SET_RATE_PARENT branch clocks. No root or init-namespace capability is required.\nUI:N - The rate request is issued synchronously from the attacker\u0027s own ioctl on a device node; no victim action, mount, or file-open by another user is needed.\nS:U - The out-of-bounds read, the disclosed data, and the misprogrammed clock registers all remain within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The traversal reads an unbounded number of out-of-bounds words from kernel .data, and the value read is returned to the caller as req-\u003erate = f-\u003efreq, observable from userspace via clk_round_rate results and debugfs clk_rate. The adjacent memory is the struct clk_rcg2 containing parent_map, freq_tbl, and clkr.hw.init pointers, so kernel pointer values can be disclosed.\nI:H - The bogus out-of-bounds entry\u0027s src/pre_div/m/n fields are fed to __clk_rcg2_configure_mnd() and written into the RCG control registers, letting the attacker drive the MMSS AXI and OCMEM NoC bus clocks to an unvalidated, out-of-spec configuration that no code path was ever meant to produce.\nA:H - The loop has no upper bound and can walk off the end of the mapped section, and on the CLK_SET_RATE_PARENT path a garbage entry with n != 0 and m == 0 hits do_div(tmp, f-\u003em), a kernel divide-by-zero oops. Even short of that, programming an out-of-spec rate on the multimedia AXI/NoC bus clock hangs the multimedia subsystem."

This UAF happens because we're accessing stale zone information of a
already removed btrfs_device in do_zone_finish().
The sequence of events is as follows:
btrfs_dev_replace_start
btrfs_scrub_dev
btrfs_dev_replace_finishing
btrfs_dev_replace_update_device_in_mapping_tree <-- devices replaced
btrfs_rm_dev_replace_free_srcdev
btrfs_free_device <-- device freed
cleaner_kthread
btrfs_delete_unused_bgs
btrfs_zone_finish
do_zone_finish <-- refers the freed device
The reason for this is that we're using a

The issue is that a tasklet could be pending on another core racing
the delete of the irq.
Fix by insuring any scheduled tasklet is killed after deleting the
irq.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netlink: Fix kernel-infoleak-after-free in __skb_datagram_iter
syzbot reported the following uninit-value access issue [1]:
netlink_to_full_skb() creates a new `skb` and puts the `skb->data`
passed as a 1st arg of netlink_to_full_skb() onto new `skb`. The data
size is specified as `len` and passed to skb_put_data(). This `len`
is based on `skb->end` that is not data offset but buffer offset. The
`skb->end` contains data and tailroom. Since the tailroom is not
initialized when the new `skb` created, KMSAN detects uninitialized
memory area when copying the data.
This patch resolved this issue by correct the len from `skb->end` to
`skb->len`, which is the actual data offset.

The data\nsize is specified as `len` and passed to skb_put_data(). This `len`\nis based on `skb-\u003eend` that is not data offset but buffer offset. The\n`skb-\u003eend` contains data and tailroom. Since the tailroom is not\ninitialized when the new `skb` created, KMSAN detects uninitialized\nmemory area when copying the data.\n\nThis patch resolved this issue by correct the len from `skb-\u003eend` to\n`skb-\u003elen`, which is the actual data offset.\n\nBUG: KMSAN: kernel-infoleak-after-free in instrument_copy_to_user include/linux/instrumented.h:114 [inline]\nBUG: KMSAN: kernel-infoleak-after-free in copy_to_user_iter lib/iov_iter.c:24 [inline]\nBUG: KMSAN: kernel-infoleak-after-free in iterate_ubuf include/linux/iov_iter.h:29 [inline]\nBUG: KMSAN: kernel-infoleak-after-free in iterate_and_advance2 include/linux/iov_iter.h:245 [inline]\nBUG: KMSAN: kernel-infoleak-after-free in iterate_and_advance include/linux/iov_iter.h:271 [inline]\nBUG: KMSAN: kernel-infoleak-after-free in _copy_to_iter+0x364/0x2520 lib/iov_iter.c:186\n instrument_copy_to_user include/linux/instrumented.h:114 [inline]\n copy_to_user_iter lib/iov_iter.c:24 [inline]\n iterate_ubuf include/linux/iov_iter.h:29 [inline]\n iterate_and_advance2 include/linux/iov_iter.h:245 [inline]\n iterate_and_advance include/linux/iov_iter.h:271 [inline]\n _copy_to_iter+0x364/0x2520 lib/iov_iter.c:186\n copy_to_iter include/linux/uio.h:197 [inline]\n simple_copy_to_iter+0x68/0xa0 net/core/datagram.c:532\n __skb_datagram_iter+0x123/0xdc0 net/core/datagram.c:420\n skb_copy_datagram_iter+0x5c/0x200 net/core/datagram.c:546\n skb_copy_datagram_msg include/linux/skbuff.h:3960 [inline]\n packet_recvmsg+0xd9c/0x2000 net/packet/af_packet.c:3482\n sock_recvmsg_nosec net/socket.c:1044 [inline]\n sock_recvmsg net/socket.c:1066 [inline]\n sock_read_iter+0x467/0x580 net/socket.c:1136\n call_read_iter include/linux/fs.h:2014 [inline]\n new_sync_read fs/read_write.c:389 [inline]\n vfs_read+0x8f6/0xe00 fs/read_write.c:470\n ksys_read+0x20f/0x4c0 fs/read_write.c:613\n __do_sys_read fs/read_write.c:623 [inline]\n __se_sys_read fs/read_write.c:621 [inline]\n __x64_sys_read+0x93/0xd0 fs/read_write.c:621\n do_syscall_x64 arch/x86/entry/common.c:52 [inline]\n do_syscall_64+0x44/0x110 arch/x86/entry/common.c:83\n entry_SYSCALL_64_after_hwframe+0x63/0x6b\n\nUninit was stored to memory at:\n skb_put_data include/linux/skbuff.h:2622 [inline]\n netlink_to_full_skb net/netlink/af_netlink.c:181 [inline]\n __netlink_deliver_tap_skb net/netlink/af_netlink.c:298 [inline]\n __netlink_deliver_tap+0x5be/0xc90 net/netlink/af_netlink.c:325\n netlink_deliver_tap net/netlink/af_netlink.c:338 [inline]\n netlink_deliver_tap_kernel net/netlink/af_netlink.c:347 [inline]\n netlink_unicast_kernel net/netlink/af_netlink.c:1341 [inline]\n netlink_unicast+0x10f1/0x1250 net/netlink/af_netlink.c:1368\n netlink_sendmsg+0x1238/0x13d0 net/netlink/af_netlink.c:1910\n sock_sendmsg_nosec net/socket.c:730 [inline]\n __sock_sendmsg net/socket.c:745 [inline]\n ____sys_sendmsg+0x9c2/0xd60 net/socket.c:2584\n ___sys_sendmsg+0x28d/0x3c0 net/socket.c:2638\n __sys_sendmsg net/socket.c:2667 [inline]\n __do_sys_sendmsg net/socket.c:2676 [inline]\n __se_sys_sendmsg net/socket.c:2674 [inline]\n __x64_sys_sendmsg+0x307/0x490 net/socket.c:2674\n do_syscall_x64 arch/x86/entry/common.c:52 [inline]\n do_syscall_64+0x44/0x110 arch/x86/entry/common.c:83\n entry_SYSCALL_64_after_hwframe+0x63/0x6b\n\nUninit was created at:\n free_pages_prepare mm/page_alloc.c:1087 [inline]\n free_unref_page_prepare+0xb0/0xa40 mm/page_alloc.c:2347\n free_unref_page_list+0xeb/0x1100 mm/page_alloc.c:2533\n release_pages+0x23d3/0x2410 mm/swap.c:1042\n free_pages_and_swap_cache+0xd9/0xf0 mm/swap_state.c:316\n tlb_batch_pages\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: amdgpu_ttm_gart_bind set gtt bound flag
Otherwise after the GTT bo is released, the GTT and gart space is freed
but amdgpu_ttm_backend_unbind will not clear the gart page table entry
and leave valid mapping entry pointing to the stale system page. Then
if GPU access the gart address mistakely, it will read undefined value
instead page fault, harder to debug and reproduce the real issue.

No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The GART retains valid entries to system pages that have been freed and recycled for arbitrary kernel and user data, so GPU reads of that aperture return reclaimed memory contents instead of faulting \u2014 a use-after-free class disclosure primitive into attacker-visible GPU buffers.\nI:H - The same stale entries are writable by the GPU, giving DMA writes into pages the kernel has reallocated for other purposes (kernel objects, page tables, other processes\u0027 data), which is arbitrary memory corruption bypassing CPU MMU protection.\nA:H - GPU DMA into reclaimed kernel pages corrupts live kernel structures leading to oops/panic, and on IOMMU-enabled systems the torn-down DMA mappings produce IO_PAGE_FAULT storms, GPU hangs, and device resets."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: Fix use-after-free bug in brcmf_cfg80211_detach
This is the candidate patch of CVE-2023-47233 :
https://nvd.nist.gov/vuln/detail/CVE-2023-47233
In brcm80211 driver,it starts with the following invoking chain
to start init a timeout worker:
->brcmf_usb_probe
->brcmf_usb_probe_cb
->brcmf_attach
->brcmf_bus_started
->brcmf_cfg80211_attach
->wl_init_priv
->brcmf_init_escan
->INIT_WORK(&cfg->escan_timeout_work,
brcmf_cfg80211_escan_timeout_worker);
If we disconnect the USB by hotplug, it will call
brcmf_usb_disconnect to make cleanup. The invoking chain is :
brcmf_usb_disconnect
->brcmf_usb_disconnect_cb
->brcmf_detach
->brcmf_cfg80211_detach
->kfree(cfg);
While the timeout woker may still be running. This will cause
a use-after-free bug on cfg in brcmf_cfg80211_escan_timeout_worker.
Fix it by deleting the timer and canceling the worker in
brcmf_cfg80211_detach.
[arend.vanspriel@broadcom.com: keep timer delete as is and cancel work just before free]

An adjacent 802.11 attacker who induces a firmware halt (a well-documented failure mode of Broadcom fullmac firmware when fed malformed frames) while the station is doing its routine background scanning triggers both sides of the race over the air.\nAC:L - The attacker controls both halves of the race \u2014 the stalled scan that guarantees the 10 s escan timer expires and the firmware halt that drives the detach \u2014 and the window is wide because the worker blocks in `brcmf_fil_cmd_data_set()` waiting on a dead firmware while `brcmf_cfg80211_detach()` frees `escan_buf` and `cfg` in parallel. The attempt is freely repeatable, and heap grooming of the freed 65000-byte buffer and `cfg` slab is standard.\nPR:N - No local account or capability is needed on the affected system: the scan is issued by the normal background supplicant/NetworkManager activity, and the detach is performed autonomously by the driver\u0027s bus-reset recovery worker in response to a firmware halt. The originally reported USB-hotplug variant likewise requires no privileges.\nUI:N - Background scanning by wpa_supplicant/NetworkManager is continuous and automatic, and the `brcmf_fw_crashed()` \u2192 bus-reset \u2192 detach sequence runs entirely inside the kernel without any user action. No victim interaction is required at any point.\nS:U - The use-after-free corrupts kernel heap objects and is exploited within the kernel\u0027s own security authority, with no crossing of a hypervisor, IOMMU, or sandbox boundary. Impact remains confined to the kernel that owns the vulnerable component.\nC:H - After the free, `brcmf_inform_bss()` walks the dangling `escan_info.escan_buf` with a length/count taken from reallocated memory, giving controlled out-of-bounds reads, and `brcmf_inform_single_bss()` hands the resulting `notify_ie`/`notify_ielen` to `cfg80211_inform_bss_data()`, which copies that kernel memory into a BSS entry retrievable by userspace via nl80211. This is an arbitrary kernel-memory read with a direct exfiltration channel.\nI:H - The worker performs an indirect call through `cfg-\u003ed11inf.decchspec`, a function pointer loaded from the freed `cfg` object, giving control-flow hijack once the slab is reallocated with attacker-controlled data, and it also writes into freed memory (`bi-\u003ectl_ch`, `cfg-\u003escan_request = NULL`, `timer_delete_sync()` on a freed `timer_list`). Combined with the stale `ifp` and `scan_request` passed into further kernel calls, this yields write and code-execution primitives.\nA:H - Even without full exploitation, dereferencing the freed `cfg`, freed `escan_buf`, and freed `brcmf_if`, and running `timer_delete_sync()`/`cfg80211_scan_done()` on freed structures, reliably produces oopses, slab corruption, and kernel panic. The WiFi interface is destroyed and the system crashes."

Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to avoid potential panic during recovery
During recovery, if FAULT_BLOCK is on, it is possible that
f2fs_reserve_new_block() will return -ENOSPC during recovery,
then it may trigger panic.
Also, if fault injection rate is 1 and only FAULT_BLOCK fault
type is on, it may encounter deadloop in loop of block reservation.
Let's change as below to fix these issues:
- remove bug_on() to avoid panic.
- limit the loop count of block reservation to avoid potential
deadloop.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: prevent kernel bug at submit_bh_wbc()
Fix a bug where nilfs_get_block() returns a successful status when
searching and inserting the specified block both fail inconsistently. If
this inconsistent behavior is not due to a previously fixed bug, then an
unexpected race is occurring, so return a temporary error -EAGAIN instead.
This prevents callers such as __block_write_begin_int() from requesting a
read into a buffer that is not mapped, which would cause the BUG_ON check
for the BH_Mapped flag in submit_bh_wbc() to fail.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: fix race between async notify and socket close
The submitting thread (one which called recvmsg/sendmsg)
may exit as soon as the async crypto handler calls complete()
so any code past that point risks touching already freed data.
Try to avoid the locking and extra flags altogether.
Have the main thread hold an extra reference, this way
we can depend solely on the atomic ref counter for
synchronization.
Don't futz with reiniting the completion, either, we are now
tightly controlling when completion fires.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wireguard: netlink: access device through ctx instead of peer
The previous commit fixed a bug that led to a NULL peer->device being
dereferenced. It's actually easier and faster performance-wise to
instead get the device from ctx->wg. This semantically makes more sense
too, since ctx->wg->peer_allowedips.seq is compared with
ctx->allowedips_seq, basing them both in ctx. This also acts as a
defence in depth provision against freed peers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/zcrypt: fix reference counting on zcrypt card objects
Tests with hot-plugging crytpo cards on KVM guests with debug
kernel build revealed an use after free for the load field of
the struct zcrypt_card. The reason was an incorrect reference
handling of the zcrypt card object which could lead to a free
of the zcrypt card object while it was still in use.
This is an example of the slab message:

"value": "AV:L - The vulnerability is reached through ioctls on the `/dev/z90crypt` misc device (ICARSAMODEXPO, ICARSACRT, ZSECSENDCPRB, ZSENDEP11CPRB), requiring local access to the s390 guest/LPAR. There is no network-facing consumer of `zcrypt_pick_queue()`.\nAC:L - The attacker fully controls the vulnerable window \u2014 `wait_for_completion_interruptible()` has no timeout, so unlimited threads park inside the pick/drop region indefinitely \u2014 and can synchronously force the removal-processing side via the `-ENODEV` retry path, which calls `ap_bus_force_rescan()` \u2192 `ap_scan_bus()` in the caller\u0027s own context. Queue teardown wakes the parked waiters with `-EAGAIN` just before the card `kfree()`, so no narrow timing window has to be won.\nPR:L - `zcrypt_unlocked_ioctl()` contains no `capable()` or `CAP_*` check; the only gate is `zcrypt_check_ioctl()` against `ap_perms`, which `ap_perms_init()` fills with 0xFF (all ioctls, all cards, all queues permitted) by default. The device node is world-accessible by design so unprivileged crypto libraries can use the adapters, so any local unprivileged user qualifies.\nUI:N - No victim action is needed \u2014 the attacker\u0027s own ioctl loop holds the stale pointer, and the attacker forces the AP bus rescan themselves via the `-ENODEV` retry path. Adapter deconfiguration is a system/hardware event, not a required user interaction.\nS:U - The use-after-free corrupts kernel slab memory within the same kernel security authority; there is no crossing of a guest/host, IOMMU, or sandbox boundary.\nC:H - Use-after-free on the freed `zcrypt_card` includes genuine reads of freed memory \u2014 `zq-\u003ezcard-\u003emax_mod_size` selects the CRB message format and `zq-\u003ezcard-\u003emax_exp_bit_length` gates the retry path \u2014 so reclaimed heap contents leak into attacker-observable behavior, and a reclaimed kmalloc-96 slot yields a general read primitive.\nI:H - The bug provides UAF writes into freed memory at known offsets: a 32-bit atomic decrement at offset 88 (`zc-\u003eload`) and a 32-bit store of 17 at offset 72 (`max_exp_bit_length`). With heap grooming of the shared kmalloc-96 cache, these controlled-offset writes into an attacker-reclaimed object are escalatable to arbitrary write and control-flow hijack.\nA:H - The reported symptom is slab poison corruption on a freed object; writing into a reclaimed kmalloc-96 slot reliably corrupts unrelated kernel structures and produces oopses or panics (immediate BUG under SLUB_DEBUG/KASAN), and the attacker can repeat it at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: fix race condition on enabling fast-xmit
fast-xmit must only be enabled after the sta has been uploaded to the driver,
otherwise it could end up passing the not-yet-uploaded sta via drv_tx calls
to the driver, leading to potential crashes because of uninitialized drv_priv
data.
Add a missing sta->uploaded check and re-check fast xmit after inserting a sta.

Per WiFi frame-injection guidance this is Adjacent, requiring only radio range of a mesh/IBSS node.\nAC:L - The attacker controls both sides of the race \u2014 the beacon that triggers `sta_info_insert_rcu()` (which sleeps in `sta_info_insert_drv_state()`, widening the window to milliseconds) and the PM-bit-toggling QoS-data frames that drive `ieee80211_check_fast_xmit()` from softirq \u2014 and can retry indefinitely by rotating source MACs; the IBSS `drv_sta_state` failure path reaches the same state deterministically.\nPR:N - Open 802.11s mesh with kernel MPM (`__mesh_sta_info_alloc`) and non-RSN IBSS (`ieee80211_ibss_finish_sta`) pre-move the peer to `IEEE80211_STA_AUTHORIZED` before insertion, so station creation happens with zero credentials. The attacker is an unauthenticated wireless peer with no account on the target.\nUI:N - No victim action is needed; a node simply operating in mesh or IBSS mode processes the attacker\u0027s beacons and data frames automatically in the RX path.\nS:U - The corruption occurs in mac80211/driver structures within the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - Passing a never-uploaded `ieee80211_sta` to `drv_tx()` makes drivers use zeroed `drv_priv` \u2014 e.g. mt76 WCID index 0, which aliases another station\u0027s hardware key/rate-table entry, so frames are transmitted under the wrong security context \u2014 and the resulting driver-state confusion reads uninitialized/foreign memory, giving a disclosure primitive.\nI:H - This is a state/type confusion on driver-private data: `list_add` on zeroed `list_head`s (ath9k `ath_atx_tid`), indexing per-station driver arrays with an uninitialized index, and in the IBSS unwind case touching resources already freed by `drv_sta_remove`, all of which constitute memory corruption leveragable for write primitives and control-flow hijack.\nA:H - The immediate and near-certain effect is a kernel oops in softirq (NULL/near-NULL dereference from zeroed driver list heads) or a firmware/queue assert, remotely triggerable and repeatable, taking down the wireless node."

Summary
In the Linux kernel, the following vulnerability has been resolved:
rds: tcp: Fix use-after-free of net in reqsk_timer_handler().
syzkaller reported a warning of netns tracker [0] followed by KASAN
splat [1] and another ref tracker warning [1].
syzkaller could not find a repro, but in the log, the only suspicious
sequence was as follows:
18:26:22 executing program 1:
r0 = socket$inet6_mptcp(0xa, 0x1, 0x106)
...
connect$inet6(r0, &(0x7f0000000080)={0xa, 0x4001, 0x0, @loopback}, 0x1c) (async)
The notable thing here is 0x4001 in connect(), which is RDS_TCP_PORT.
So, the scenario would be:
1. unshare(CLONE_NEWNET) creates a per netns tcp listener in
rds_tcp_listen_init().
2. syz-executor connect()s to it and creates a reqsk.
3. syz-executor exit()s immediately.
4. netns is dismantled. [0]
5. reqsk timer is fired, and UAF happens while freeing reqsk. [1]
6. listener is freed after RCU grace period. [2]
Basically, reqsk assumes that the listener guarantees netns safety
until all reqsk timers are expired by holding the listener's refcount.
However, this was not the case for kernel sockets.
Commit 740ea3c4a0b2 ("tcp: Clean up kernel listener's reqsk in
inet_twsk_purge()") fixed this issue only for per-netns ehash.
Let's apply the same fix for the global ehash.

Summary
In the Linux kernel, the following vulnerability has been resolved:
md/dm-raid: don't call md_reap_sync_thread() directly
Currently md_reap_sync_thread() is called from raid_message() directly
without holding 'reconfig_mutex', this is definitely unsafe because
md_reap_sync_thread() can change many fields that is protected by
'reconfig_mutex'.
However, hold 'reconfig_mutex' here is still problematic because this
will cause deadlock, for example, commit 130443d60b1b ("md: refactor
idle/frozen_sync_thread() to fix deadlock").
Fix this problem by using stop_sync_thread() to unregister sync_thread,
like md/raid did.

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

The same namespace also lets the attacker send the packets that dereference the freed element, making the whole chain self-contained for an ordinary local user.\nUI:N - The attacker performs every step \u2014 creating the set, driving the add/delete batch, and generating the traffic that hits the stale mapping entry. No victim action is involved.\nS:U - The corruption is confined to the kernel\u0027s own heap and results in standard kernel privilege escalation rather than crossing a hypervisor, IOMMU, or other separate security authority.\nC:H - The freed nft_pipapo_elem stays reachable from the packet lookup path, and nft_lookup_eval() copies nft_set_ext_data() from that freed object into registers, giving an attacker-observable read of reclaimed kernel heap that can be sprayed with sensitive data or kernel pointers.\nI:H - This is a use-after-free on an object whose contents the attacker can control via heap spraying; for verdict maps the freed verdict.chain pointer is followed by nft_do_chain(), and nft_set_elem_update_expr() executes stateful expressions out of the freed memory, yielding write and control-flow-hijack primitives.\nA:H - Even without full exploitation, the dangling f-\u003emt[b].e pointer is dereferenced on every matching packet, producing KASAN splats, oopses, and kernel panics (the reported symptom was a crash)."

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: Fix clk_core_get NULL dereference
It is possible for clk_core_get to dereference a NULL in the following
sequence:
clk_core_get()
of_clk_get_hw_from_clkspec()
__of_clk_get_hw_from_provider()
__clk_get_hw()
__clk_get_hw() can return NULL which is dereferenced by clk_core_get() at
hw->core.
Prior to commit dde4eff47c82 ("clk: Look for parents with clkdev based
clk_lookups") the check IS_ERR_OR_NULL() was performed which would have
caught the NULL.
Reading the description of this function it talks about returning NULL but
that cannot be so at the moment.
Update the function to check for hw before dereferencing it and return NULL
if hw is NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix failure to detect DAT corruption in btree and direct mappings
Patch series "nilfs2: fix kernel bug at submit_bh_wbc()".
This resolves a kernel BUG reported by syzbot. Since there are two
flaws involved, I've made each one a separate patch.
The first patch alone resolves the syzbot-reported bug, but I think
both fixes should be sent to stable, so I've tagged them as such.
This patch (of 2):
Syzbot has reported a kernel bug in submit_bh_wbc() when writing file data
to a nilfs2 file system whose metadata is corrupted.
There are two flaws involved in this issue.
The first flaw is that when nilfs_get_block() locates a data block using
btree or direct mapping, if the disk address translation routine
nilfs_dat_translate() fails with internal code -ENOENT due to DAT metadata
corruption, it can be passed back to nilfs_get_block(). This causes
nilfs_get_block() to misidentify an existing block as non-existent,
causing both data block lookup and insertion to fail inconsistently.
The second flaw is that nilfs_get_block() returns a successful status in
this inconsistent state. This causes the caller __block_write_begin_int()
or others to request a read even though the buffer is not mapped,
resulting in a BUG_ON check for the BH_Mapped flag in submit_bh_wbc()
failing.
This fixes the first issue by changing the return value to code -EINVAL
when a conversion using DAT fails with code -ENOENT, avoiding the
conflicting condition that leads to the kernel bug described above. Here,
code -EINVAL indicates that metadata corruption was detected during the
block lookup, which will be properly handled as a file system error and
converted to -EIO when passing through the nilfs2 bmap layer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: fix potential "struct net" leak in inet6_rtm_getaddr()
It seems that if userspace provides a correct IFA_TARGET_NETNSID value
but no IFA_ADDRESS and IFA_LOCAL attributes, inet6_rtm_getaddr()
returns -EINVAL with an elevated "struct net" refcount.

There is no remote or adjacent-network path into `gtp_newlink()`.\nAC:L - The attacker creates and controls both sides of the race \u2014 one thread\u0027s own `RTM_NEWLINK` triggers `request_module(\"rtnl-link-gtp\")` while sibling threads block on `rtnl_lock` inside `__rtnl_newlink()`, and `rtnl_link_register()` releasing that lock inside `gtp_init()` hands a waiter the lock before `register_pernet_subsys()` completes. Syzkaller reproduced it from an ordinary userspace binary, and the same inverted ordering is also hit deterministically on the module-init error path.\nPR:L - `rtnetlink_rcv_msg()` only requires `netlink_net_capable(skb, CAP_NET_ADMIN)`, which is evaluated against the socket\u0027s `net-\u003euser_ns`, so an unprivileged user obtains it with `unshare -Urn`. Module autoload via `request_module()` in `__rtnl_newlink()` adds no further capability gate, so no real root is needed.\nUI:N - The attacker performs the entire sequence \u2014 autoload trigger plus racing link-creation requests \u2014 from their own threads. No victim action or pre-existing system state is required.\nS:U - The corruption stays within the kernel\u0027s own memory and security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - `ops_free_list()` frees the per-net `struct gtp_net` without clearing `ng-\u003eptr[id]`, so `net_generic()` returns a dangling pointer whose reused slab contents are read as a list head and subsequently walked and marshalled to userspace by `gtp_genl_dump_pdp()`, giving a use-after-free read primitive over adjacent kernel heap data.\nI:H - `__list_add_rcu()` performs `next-\u003eprev = new` where `next` is read from the freed/garbage `gn-\u003egtp_dev_list`, so an attacker who sprays the reallocated 16-byte object controls the destination and writes a kernel heap pointer to an arbitrary address \u2014 a write primitive suitable for control-flow hijacking.\nA:H - The unfixed path reliably produces a general protection fault / null-pointer dereference in `gtp_newlink()` (the reported oops), and the use-after-free variant corrupts the slab, both resulting in kernel crashes."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7925e: fix use-after-free in free_irq()
From commit a304e1b82808 ("[PATCH] Debug shared irqs"), there is a test
to make sure the shared irq handler should be able to handle the unexpected
event after deregistration. For this case, let's apply MT76_REMOVED flag to
indicate the device was removed and do not run into the resource access
anymore.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: ttpci: fix two memleaks in budget_av_attach
When saa7146_register_device and saa7146_vv_init fails, budget_av_attach
should free the resources it allocates, like the error-handling of
ttpci_budget_init does. Besides, there are two fixme comment refers to
such deallocations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: release mutex after nft_gc_seq_end from abort path
The commit mutex should not be released during the critical section
between nft_gc_seq_begin() and nft_gc_seq_end(), otherwise, async GC
worker could collect expired objects and get the released commit lock
within the same GC sequence.
nf_tables_module_autoload() temporarily releases the mutex to load
module dependencies, then it goes back to replay the transaction again.
Move it at the end of the abort phase after nft_gc_seq_end() is called.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/vkms: Avoid reading beyond LUT array
When the floor LUT index (drm_fixp2int(lut_index) is the last
index of the array the ceil LUT index will point to an entry
beyond the array. Make sure we guard against it and use the
value of the floor LUT index.
v3:
- Drop bits from commit description that didn't contribute
anything of value

In the Linux kernel, the following vulnerability has been resolved:
do_sys_name_to_handle(): use kzalloc() to fix kernel-infoleak
syzbot identified a kernel information leak vulnerability in
do_sys_name_to_handle() and issued the following report [1].

Per Chuck Lever's suggestion, use kzalloc() instead of kmalloc() to
solve the problem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm-raid456, md/raid456: fix a deadlock for dm-raid456 while io concurrent with reshape
For raid456, if reshape is still in progress, then IO across reshape
position will wait for reshape to make progress. However, for dm-raid,
in following cases reshape will never make progress hence IO will hang:
1) the array is read-only;
2) MD_RECOVERY_WAIT is set;
3) MD_RECOVERY_FROZEN is set;
After commit c467e97f079f ("md/raid6: use valid sector values to determine
if an I/O should wait on the reshape") fix the problem that IO across
reshape position doesn't wait for reshape, the dm-raid test
shell/lvconvert-raid-reshape.sh start to hang:

This is because reshape can't make progress.
For md/raid, the problem doesn't exist because register new sync_thread
doesn't rely on the IO to be done any more:
1) If array is read-only, it can switch to read-write by ioctl/sysfs;
2) md/raid never set MD_RECOVERY_WAIT;
3) If MD_RECOVERY_FROZEN is set, mddev_suspend() doesn't hold
'reconfig_mutex', hence it can be cleared and reshape can continue by
sysfs api 'sync_action'.
However, I'm not sure yet how to avoid the problem in dm-raid yet. This
patch on the one hand make sure raid_message() can't change
sync_thread() through raid_message() after presuspend(), on the other
hand detect the above 3 cases before wait for IO do be done in
dm_suspend(), and let dm-raid requeue those IO.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: sh: aica: reorder cleanup operations to avoid UAF bugs
The dreamcastcard->timer could schedule the spu_dma_work and the
spu_dma_work could also arm the dreamcastcard->timer.
When the snd_pcm_substream is closing, the aica_channel will be
deallocated. But it could still be dereferenced in the worker
thread. The reason is that del_timer() will return directly
regardless of whether the timer handler is running or not and
the worker could be rescheduled in the timer handler. As a result,
the UAF bug will happen. The racy situation is shown below:
(Thread 1) | (Thread 2)
snd_aicapcm_pcm_close() |
... | run_spu_dma() //worker
| mod_timer()
flush_work() |
del_timer() | aica_period_elapsed() //timer
kfree(dreamcastcard->channel) | schedule_work()
| run_spu_dma() //worker
... | dreamcastcard->channel-> //USE
In order to mitigate this bug and other possible corner cases,
call mod_timer() conditionally in run_spu_dma(), then implement
PCM sync_stop op to cancel both the timer and worker. The sync_stop
op will be called from PCM core appropriately when needed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
pmdomain: mediatek: fix race conditions with genpd
If the power domains are registered first with genpd and *after that*
the driver attempts to power them on in the probe sequence, then it is
possible that a race condition occurs if genpd tries to power them on
in the same time.
The same is valid for powering them off before unregistering them
from genpd.
Attempt to fix race conditions by first removing the domains from genpd
and *after that* powering down domains.
Also first power up the domains and *after that* register them
to genpd.

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: gcc-ipq5018: fix terminating of frequency table arrays
The frequency table arrays are supposed to be terminated with an
empty element. Add such entry to the end of the arrays where it
is missing in order to avoid possible out-of-bound access when
the table is traversed by functions like qcom_find_freq() or
qcom_find_freq_floor().

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: Unmap the surface before resetting it on a plane state
Switch to a new plane state requires unreferencing of all held surfaces.
In the work required for mob cursors the mapped surfaces started being
cached but the variable indicating whether the surface is currently
mapped was not being reset. This leads to crashes as the duplicated
state, incorrectly, indicates the that surface is mapped even when
no surface is present. That's because after unreferencing the surface
it's perfectly possible for the plane to be backed by a bo instead of a
surface.
Reset the surface mapped flag when unreferencing the plane state surface
to fix null derefs in cleanup. Fixes crashes in KDE KWin 6.0 on Wayland:

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: set dormant flag on hook register failure
We need to set the dormant flag again if we fail to register
the hooks.
During memory pressure hook registration can fail and we end up
with a table marked as active but no registered hooks.
On table/base chain deletion, nf_tables will attempt to unregister
the hook again which yields a warn splat from the nftables core.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: iaa - Fix nr_cpus < nr_iaa case
If nr_cpus < nr_iaa, the calculated cpus_per_iaa will be 0, which
causes a divide-by-0 in rebalance_wq_table().
Make sure cpus_per_iaa is 1 in that case, and also in the nr_iaa == 0
case, even though cpus_per_iaa is never used if nr_iaa == 0, for
paranoia.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_flow_offload: reset dst in route object after setting up flow
dst is transferred to the flow object, route object does not own it
anymore. Reset dst in route object, otherwise if flow_offload_add()
fails, error path releases dst twice, leading to a refcount underflow.

Per kernel scoring convention netfilter/nftables is treated as Local, even though the final trigger is a forwarded packet.\nAC:L - The attacker deterministically forces `flow_offload_add()` to return -EEXIST because the flow_offload_tuple hash key excludes the conntrack zone, so two zone-separated conntracks with the same 5-tuple and ingress ifindex always collide. No race and no uncontrolled memory-layout condition is involved.\nPR:L - Configuring the flowtable and rules only needs CAP_NET_ADMIN evaluated via `netlink_net_capable()`, which an unprivileged user obtains with `unshare -Urn`; forwarded traffic can then be generated entirely inside that namespace with veth pairs.\nUI:N - The attacker sets up the namespace, nftables ruleset and traffic themselves; no victim action of any kind is needed.\nS:U - The corruption is confined to kernel memory managed by the same kernel security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:H - The dst refcount underflow frees a `struct dst_entry` that remains referenced by skbs and the route cache, giving a use-after-free on a heap object the attacker can reclaim and read back, enabling disclosure of arbitrary kernel memory.\nI:H - The freed dst is reclaimable via heap spray and contains `ops`, `input()` and `output()` function pointers dereferenced on every forwarded packet, yielding an arbitrary-write/control-flow-hijack primitive.\nA:H - The premature free of a live routing cache entry causes immediate use-after-free on the packet forwarding path, reliably producing an oops or panic, and can be repeated at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix use-after-free bug
The bug can be triggered by sending a single amdgpu_gem_userptr_ioctl
to the AMDGPU DRM driver on any ASICs with an invalid address and size.
The bug was reported by Joonkyo Jung <joonkyoj@yonsei.ac.kr>.
For example the following code:
static void Syzkaller1(int fd)
{
struct drm_amdgpu_gem_userptr arg;
int ret;
arg.addr = 0xffffffffffff0000;
arg.size = 0x80000000; /*2 Gb*/
arg.flags = 0x7;
ret = drmIoctl(fd, 0xc1186451/*amdgpu_gem_userptr_ioctl*/, &arg);
}
Due to the address and size are not valid there is a failure in
amdgpu_hmm_register->mmu_interval_notifier_insert->__mmu_interval_notifier_insert->
check_shl_overflow, but we even the amdgpu_hmm_register failure we still call
amdgpu_hmm_unregister into amdgpu_gem_object_free which causes access to a bad address.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: fix kernel crash when 1588 is received on HIP08 devices
The HIP08 devices does not register the ptp devices, so the
hdev->ptp is NULL, but the hardware can receive 1588 messages,
and set the HNS3_RXD_TS_VLD_B bit, so, if match this case, the
access of hdev->ptp->flags will cause a kernel crash:

Summary
In the Linux kernel, the following vulnerability has been resolved:
vfio/pci: Disable auto-enable of exclusive INTx IRQ
Currently for devices requiring masking at the irqchip for INTx, ie.
devices without DisINTx support, the IRQ is enabled in request_irq()
and subsequently disabled as necessary to align with the masked status
flag. This presents a window where the interrupt could fire between
these events, resulting in the IRQ incrementing the disable depth twice.
This would be unrecoverable for a user since the masked flag prevents
nested enables through vfio.
Instead, invert the logic using IRQF_NO_AUTOEN such that exclusive INTx
is never auto-enabled, then unmask as required.

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: max310x: fix NULL pointer dereference in I2C instantiation
When trying to instantiate a max14830 device from userspace:
echo max14830 0x60 > /sys/bus/i2c/devices/i2c-2/new_device
we get the following error:
Unable to handle kernel NULL pointer dereference at virtual address...
...
Call trace:
max310x_i2c_probe+0x48/0x170 [max310x]
i2c_device_probe+0x150/0x2a0
...
Add check for validity of devtype to prevent the error, and abort probe
with a meaningful error message.

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: gcc-ipq6018: fix terminating of frequency table arrays
The frequency table arrays are supposed to be terminated with an
empty element. Add such entry to the end of the arrays where it
is missing in order to avoid possible out-of-bound access when
the table is traversed by functions like qcom_find_freq() or
qcom_find_freq_floor().
Only compile tested.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbcon: always restore the old font data in fbcon_do_set_font()
Commit a5a923038d70 (fbdev: fbcon: Properly revert changes when
vc_resize() failed) started restoring old font data upon failure (of
vc_resize()). But it performs so only for user fonts. It means that the
"system"/internal fonts are not restored at all. So in result, the very
first call to fbcon_do_set_font() performs no restore at all upon
failing vc_resize().
This can be reproduced by Syzkaller to crash the system on the next
invocation of font_get(). It's rather hard to hit the allocation failure
in vc_resize() on the first font_set(), but not impossible. Esp. if
fault injection is used to aid the execution/failure. It was
demonstrated by Sirius:
BUG: unable to handle page fault for address: fffffffffffffff8
#PF: supervisor read access in kernel mode
#PF: error_code(0x0000) - not-present page
PGD cb7b067 P4D cb7b067 PUD cb7d067 PMD 0
Oops: 0000 [#1] PREEMPT SMP KASAN
CPU: 1 PID: 8007 Comm: poc Not tainted 6.7.0-g9d1694dc91ce #20
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014
RIP: 0010:fbcon_get_font+0x229/0x800 drivers/video/fbdev/core/fbcon.c:2286
Call Trace:
<TASK>

...
So restore the font data in any case, not only for user fonts. Note the
later 'if' is now protected by 'old_userfont' and not 'old_data' as the
latter is always set now. (And it is supposed to be non-NULL. Otherwise
we would see the bug above again.)

But it performs so only for user fonts. It means that the\n\"system\"/internal fonts are not restored at all.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gt: Reset queue_priority_hint on parking
Originally, with strict in order execution, we could complete execution
only when the queue was empty. Preempt-to-busy allows replacement of an
active request that may complete before the preemption is processed by
HW. If that happens, the request is retired from the queue, but the
queue_priority_hint remains set, preventing direct submission until
after the next CS interrupt is processed.
This preempt-to-busy race can be triggered by the heartbeat, which will
also act as the power-management barrier and upon completion allow us to
idle the HW. We may process the completion of the heartbeat, and begin
parking the engine before the CS event that restores the
queue_priority_hint, causing us to fail the assertion that it is MIN.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/i915/gt: Reset queue_priority_hint on parking\n\nOriginally, with strict in order execution, we could complete execution\nonly when the queue was empty. Preempt-to-busy allows replacement of an\nactive request that may complete before the preemption is processed by\nHW. If that happens, the request is retired from the queue, but the\nqueue_priority_hint remains set, preventing direct submission until\nafter the next CS interrupt is processed.\n\nThis preempt-to-busy race can be triggered by the heartbeat, which will\nalso act as the power-management barrier and upon completion allow us to\nidle the HW. We may process the completion of the heartbeat, and begin\nparking the engine before the CS event that restores the\nqueue_priority_hint, causing us to fail the assertion that it is MIN.\n\n\u003c3\u003e[ 166.210729] __engine_park:283 GEM_BUG_ON(engine-\u003esched_engine-\u003equeue_priority_hint != (-((int)(~0U \u003e\u003e 1)) - 1))\n\u003c0\u003e[ 166.210781] Dumping ftrace buffer:\n\u003c0\u003e[ 166.210795] ---------------------------------\n...\n\u003c0\u003e[ 167.302811] drm_fdin-1097 2..s1. 165741070us : trace_ports: 0000:00:02.0 rcs0: promote { ccid:20 1217:2 prio 0 }\n\u003c0\u003e[ 167.302861] drm_fdin-1097 2d.s2. 165741072us : execlists_submission_tasklet: 0000:00:02.0 rcs0: preempting last=1217:2, prio=0, hint=2147483646\n\u003c0\u003e[ 167.302928] drm_fdin-1097 2d.s2. 165741072us : __i915_request_unsubmit: 0000:00:02.0 rcs0: fence 1217:2, current 0\n\u003c0\u003e[ 167.302992] drm_fdin-1097 2d.s2. 165741073us : __i915_request_submit: 0000:00:02.0 rcs0: fence 3:4660, current 4659\n\u003c0\u003e[ 167.303044] drm_fdin-1097 2d.s1. 165741076us : execlists_submission_tasklet: 0000:00:02.0 rcs0: context:3 schedule-in, ccid:40\n\u003c0\u003e[ 167.303095] drm_fdin-1097 2d.s1. 165741077us : trace_ports: 0000:00:02.0 rcs0: submit { ccid:40 3:4660* prio 2147483646 }\n\u003c0\u003e[ 167.303159] kworker/-89 11..... 165741139us : i915_request_retire.part.0: 0000:00:02.0 rcs0: fence c90:2, current 2\n\u003c0\u003e[ 167.303208] kworker/-89 11..... 165741148us : __intel_context_do_unpin: 0000:00:02.0 rcs0: context:c90 unpin\n\u003c0\u003e[ 167.303272] kworker/-89 11..... 165741159us : i915_request_retire.part.0: 0000:00:02.0 rcs0: fence 1217:2, current 2\n\u003c0\u003e[ 167.303321] kworker/-89 11..... 165741166us : __intel_context_do_unpin: 0000:00:02.0 rcs0: context:1217 unpin\n\u003c0\u003e[ 167.303384] kworker/-89 11..... 165741170us : i915_request_retire.part.0: 0000:00:02.0 rcs0: fence 3:4660, current 4660\n\u003c0\u003e[ 167.303434] kworker/-89 11d..1. 165741172us : __intel_context_retire: 0000:00:02.0 rcs0: context:1216 retire runtime: { total:56028ns, avg:56028ns }\n\u003c0\u003e[ 167.303484] kworker/-89 11..... 165741198us : __engine_park: 0000:00:02.0 rcs0: parked\n\u003c0\u003e[ 167.303534] \u003cidle\u003e-0 5d.H3. 165741207us : execlists_irq_handler: 0000:00:02.0 rcs0: semaphore yield: 00000040\n\u003c0\u003e[ 167.303583] kworker/-89 11..... 165741397us : __intel_context_retire: 0000:00:02.0 rcs0: context:1217 retire runtime: { total:325575ns, avg:0ns }\n\u003c0\u003e[ 167.303756] kworker/-89 11..... 165741777us : __intel_context_retire: 0000:00:02.0 rcs0: context:c90 retire runtime: { total:0ns, avg:0ns }\n\u003c0\u003e[ 167.303806] kworker/-89 11..... 165742017us : __engine_park: __engine_park:283 GEM_BUG_ON(engine-\u003esched_engine-\u003equeue_priority_hint != (-((int)(~0U \u003e\u003e 1)) - 1))\n\u003c0\u003e[ 167.303811] ---------------------------------\n\u003c4\u003e[ 167.304722] ------------[ cut here ]------------\n\u003c2\u003e[ 167.304725] kernel BUG at drivers/gpu/drm/i915/gt/intel_engine_pm.c:283!\n\u003c4\u003e[ 167.304731] invalid opcode: 0000 [#1] PREEMPT SMP NOPTI\n\u003c4\u003e[ 167.304734] CPU: 11 PID: 89 Comm: kworker/11:1 Tainted: G W 6.8.0-rc2-CI_DRM_14193-gc655e0fd2804+ #1\n\u003c4\u003e[ 167.304736] Hardware name: Intel Corporation Rocket Lake Client Platform/RocketLake S UDIMM 6L RVP, BIOS RKLSFWI1.R00.3173.A03.2204210138 04/21/2022\n\u003c4\u003e[ 167.304738] Workqueue: i915-unordered retire_work_handler [i915]\n\u003c4\u003e[ 16\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
efi/capsule-loader: fix incorrect allocation size
gcc-14 notices that the allocation with sizeof(void) on 32-bit architectures
is not enough for a 64-bit phys_addr_t:
drivers/firmware/efi/capsule-loader.c: In function 'efi_capsule_open':
drivers/firmware/efi/capsule-loader.c:295:24: error: allocation of insufficient size '4' for type 'phys_addr_t' {aka 'long long unsigned int'} with size '8' [-Werror=alloc-size]
295 | cap_info->phys = kzalloc(sizeof(void *), GFP_KERNEL);
| ^
Use the correct type instead here.

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfs: fix panic when nfs4_ff_layout_prepare_ds() fails
We've been seeing the following panic in production
BUG: kernel NULL pointer dereference, address: 0000000000000065

Inspecting the core with drgn I was able to pull this
>>> prog.crashed_thread().stack_trace()[0]
#0 at 0xffffffffa079657a (ff_layout_cancel_io+0x3a/0x84) in ff_layout_cancel_io at fs/nfs/flexfilelayout/flexfilelayout.c:2021:27
>>> prog.crashed_thread().stack_trace()[0]['idx']
(u32)1
>>> prog.crashed_thread().stack_trace()[0]['flseg'].mirror_array[1].mirror_ds
(struct nfs4_ff_layout_ds *)0xffffffffffffffed
This is clear from the stack trace, we call nfs4_ff_layout_prepare_ds()
which could error out initializing the mirror_ds, and then we go to
clean it all up and our check is only for if (!mirror->mirror_ds). This
is inconsistent with the rest of the users of mirror_ds, which have
if (IS_ERR_OR_NULL(mirror_ds))
to keep from tripping over this exact scenario. Fix this up in
ff_layout_cancel_io() to make sure we don't panic when we get an error.
I also spot checked all the other instances of checking mirror_ds and we
appear to be doing the correct checks everywhere, only unconditionally
dereferencing mirror_ds when we know it would be valid.

"value": "AV:N - The vulnerable code path is driven entirely by data from the remote NFS server \u2014 a malicious, compromised, or spoofed NFSv4.1/4.2 server forces GETDEVICEINFO to fail (error reply, malformed XDR, or no usable DS addresses), which is what plants the ERR_PTR that is later dereferenced. The NFS client processes this attacker-controlled protocol data over the network with no locality restriction.\nAC:L - The server-side attacker fully and deterministically controls the trigger: grant a flexfiles layout, then fail the GETDEVICEINFO for one of its device IDs, and the very next write/fsync on that inode panics the client. No race, no memory-layout grooming, and the flexfiles layout driver is present in default distro NFSv4.1 configurations.\nPR:N - The attacker acts as the NFS server (or an RPC-reply injector on the path) and needs no credentials or account on the victim client. Even in the purely local framing, any unprivileged user with write access to a file on the mount reaches nfs_writepages()\u2192ff_layout_pg_init_write(), so no elevated privileges are required in any scenario.\nUI:N - No victim action is needed at exploit time \u2014 the mount is pre-existing infrastructure, and normal background writeback or any application fsync() drives the path automatically. A compromised server can simply wait for routine client I/O.\nS:U - The fault occurs in the NFS client within the kernel\u0027s own security authority; nothing crosses into another VM, hypervisor, or IOMMU/DMA boundary.\nC:N - The dereferenced value can only ever be ERR_PTR(-ENODEV), producing a fixed low address (0x65) below mmap_min_addr that faults immediately. No attacker data is read back and no kernel memory is disclosed.\nI:N - The bug is a read of an invalid fixed pointer with no write to kernel memory and no attacker influence over the faulting address, so there is no data modification or control-flow hijack primitive.\nA:H - The result is an unrecoverable kernel NULL-pointer dereference oops in writeback context (as captured in the production panic in the fix commit), taking down the client system. It can be re-triggered at will by the remote server, so affected clients can be kept permanently down."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix double free of the ha->vp_map pointer
Coverity scan reported potential risk of double free of the pointer
ha->vp_map. ha->vp_map was freed in qla2x00_mem_alloc(), and again freed
in function qla2x00_mem_free(ha).
Assign NULL to vp_map and kfree take care of NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
power: supply: bq27xxx-i2c: Do not free non existing IRQ
The bq27xxx i2c-client may not have an IRQ, in which case
client->irq will be 0. bq27xxx_battery_i2c_probe() already has
an if (client->irq) check wrapping the request_threaded_irq().
But bq27xxx_battery_i2c_remove() unconditionally calls
free_irq(client->irq) leading to:
[ 190.310742] ------------[ cut here ]------------
[ 190.310843] Trying to free already-free IRQ 0
[ 190.310861] WARNING: CPU: 2 PID: 1304 at kernel/irq/manage.c:1893 free_irq+0x1b8/0x310
Followed by a backtrace when unbinding the driver. Add
an if (client->irq) to bq27xxx_battery_i2c_remove() mirroring
probe() to fix this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: edia: dvbdev: fix a use-after-free
In dvb_register_device, *pdvbdev is set equal to dvbdev, which is freed
in several error-handling paths. However, *pdvbdev is not set to NULL
after dvbdev's deallocation, causing use-after-frees in many places,
for example, in the following call chain:
budget_register
|-> dvb_dmxdev_init
|-> dvb_register_device
|-> dvb_dmxdev_release
|-> dvb_unregister_device
|-> dvb_remove_device
|-> dvb_device_put
|-> kref_put
When calling dvb_unregister_device, dmxdev->dvbdev (i.e. *pdvbdev in
dvb_register_device) could point to memory that had been freed in
dvb_register_device. Thereafter, this pointer is transferred to
kref_put and triggering a use-after-free.

Per the UAF guidance, a use-after-free with attacker-influenceable triggering conditions is Low.\nPR:L - A basic unprivileged local account suffices to generate the memory pressure that forces the error paths and to drive repeated registration attempts; no CAP_SYS_ADMIN or root in the init namespace is required to reach dvb-core\u0027s registration failure handling.\nUI:N - No victim action is needed \u2014 the attacker drives both the allocation failure and the device registration attempt themselves, and the stale pointer is consumed automatically by the driver\u0027s own error-unwind path.\nS:U - The corruption is confined to kernel heap and kernel static data within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - The dangling struct dvb_device is dereferenced after free (dmxdev-\u003edvbdev-\u003eusers, -\u003ewait_queue, -\u003eminor), so heap-spray reallocation of that slab object gives the attacker control over the freed contents and, via the list_del unlink and wait-queue callback primitives, a route to arbitrary kernel memory disclosure.\nI:H - The use-after-free yields multiple write primitives: list_del() on freed memory is a classic write-what-where unlink, dvb_minors[dvbdev-\u003eminor] = NULL writes at an attacker-chosen offset from a static array, and kref_put() double-frees the object \u2014 collectively sufficient for control-flow hijack and privilege escalation.\nA:H - Even without full exploitation, dereferencing and kfree()ing already-freed memory reliably produces slab corruption, a double free, and out-of-bounds writes, resulting in kernel oops or panic."

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/srpt: Do not register event handler until srpt device is fully setup
Upon rare occasions, KASAN reports a use-after-free Write
in srpt_refresh_port().
This seems to be because an event handler is registered before the
srpt device is fully setup and a race condition upon error may leave a
partially setup event handler in place.
Instead, only register the event handler after srpt device initialization
is complete.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: regenerate buddy after block freeing failed if under fc replay
This mostly reverts commit 6bd97bf273bd ("ext4: remove redundant
mb_regenerate_buddy()") and reintroduces mb_regenerate_buddy(). Based on
code in mb_free_blocks(), fast commit replay can end up marking as free
blocks that are already marked as such. This causes corruption of the
buddy bitmap so we need to regenerate it in that case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
quota: Fix potential NULL pointer dereference
Below race may cause NULL pointer dereference
P1 P2
dquot_free_inode quota_off
drop_dquot_ref
remove_dquot_ref
dquots = i_dquot(inode)
dquots = i_dquot(inode)
srcu_read_lock
dquots[cnt]) != NULL (1)
dquots[type] = NULL (2)
spin_lock(&dquots[cnt]->dq_dqb_lock) (3)
....
If dquot_free_inode(or other routines) checks inode's quota pointers (1)
before quota_off sets it to NULL(2) and use it (3) after that, NULL pointer
dereference will be triggered.
So let's fix it by using a temporary pointer to avoid this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vfio/pci: Create persistent INTx handler
A vulnerability exists where the eventfd for INTx signaling can be
deconfigured, which unregisters the IRQ handler but still allows
eventfds to be signaled with a NULL context through the SET_IRQS ioctl
or through unmask irqfd if the device interrupt is pending.
Ideally this could be solved with some additional locking; the igate
mutex serializes the ioctl and config space accesses, and the interrupt
handler is unregistered relative to the trigger, but the irqfd path
runs asynchronous to those. The igate mutex cannot be acquired from the
atomic context of the eventfd wake function. Disabling the irqfd
relative to the eventfd registration is potentially incompatible with
existing userspace.
As a result, the solution implemented here moves configuration of the
INTx interrupt handler to track the lifetime of the INTx context object
and irq_type configuration, rather than registration of a particular
trigger eventfd. Synchronization is added between the ioctl path and
eventfd_signal() wrapper such that the eventfd trigger can be
dynamically updated relative to in-flight interrupts or irqfd callbacks.

For the additional eventfd_ctx use-after-free, the attacker controls both sides of the race (one thread looping trigger replacement, another firing the unmask irqfd and the device\u0027s own INTx line).\nPR:L - No capability is checked anywhere on the path; CAP_SYS_RAWIO applies only to no-IOMMU mode. Access is granted by ordinary file permissions on the VFIO device/group node, which is exactly the intended deployment for unprivileged userspace drivers (DPDK/SPDK), libvirt-run QEMU as a non-root user, and containers with delegated /dev/vfio access.\nUI:N - The attacker performs the entire sequence itself via ioctls on a device fd it already holds; no victim action, mount, or file-open is required.\nS:U - The bug is an in-kernel software defect reached through a legitimate ioctl by the process that already owns the device; no IOMMU/DMA boundary is bypassed and no guest-to-host boundary is crossed. Vulnerable and impacted components are both the host kernel.\nC:H - The commit also closes a use-after-free of the eventfd_ctx released by the ioctl path while the asynchronous irqfd inject workqueue is still dereferencing it (the reason synchronize_irq()/vfio_virqfd_flush_thread() were added). Control of the reclaimed slab object yields an arbitrary kernel read primitive via the wait-queue walk.\nI:H - The same use-after-free lets eventfd_signal() write into a reallocated, attacker-sprayed object (ctx-\u003ecount++) and call a function pointer through wake_up_locked_poll()\u0027s wait-queue traversal, giving a control-flow hijack primitive. On configurations permitting low-address mappings, the NULL dereference itself becomes an attacker-controlled write/call.\nA:H - Any user with access to a VFIO device can reliably oops the kernel in three ioctls via eventfd_signal(NULL) taking a spinlock at a NULL offset, and the use-after-free adds further memory corruption crashes. With panic_on_oops this is a full host panic."

Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/hfi1: Fix sdma.h tx->num_descs off-by-one error
Unfortunately the commit `fd8958efe877` introduced another error
causing the `descs` array to overflow. This reults in further crashes
easily reproducible by `sendmsg` system call.

If an SDMA send consists of exactly 6 descriptors and requires dword
padding (in the 7th descriptor), the sdma_txreq descriptor array is not
properly expanded and the packet will overflow into the container
structure. This results in a panic when the send completion runs. The
exact panic varies depending on what elements of the container structure
get corrupted. The fix is to use the correct expression in
_pad_sdma_tx_descs() to test the need to expand the descriptor array.
With this patch the crashes are no longer reproducible and the machine is
stable.

A remote peer cannot dictate the local skb fragment layout, so this is a local syscall vector, not network.\nAC:L - There is no race and no memory-layout dependency: the attacker deterministically chooses 4 page fragments plus a payload length not divisible by 4, which makes `num_desc` equal `desc_limit` exactly when padding is appended. Every attempt with that shape overflows `descs[6]`.\nPR:L - Any unprivileged local account can send datagrams out an IPoIB interface; no capability, no `/dev/infiniband` or `/dev/hfi1` access, and no namespace trickery is required. The `hfi1_ipoib_send` path is reached from the generic `dev_hard_start_xmit` transmit path available to all users.\nUI:N - The attacker\u0027s own `sendmsg` call triggers the overflow and the subsequent completion/reuse of the corrupted txreq; no administrator or victim action is involved.\nS:U - The out-of-bounds write stays within kernel memory managed by the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The overflow clobbers `ipoib_txreq.sdma_hdr`, a pointer that is later handed to `sdma_txadd_kvaddr()`/`dma_map_single()` as the packet-header DMA source, so corrupted-pointer contents can be DMA\u0027d onto the fabric; more generally an attacker-triggered out-of-bounds write over adjacent pointer fields is memory corruption leverageable for disclosure.\nI:H - This is a straight out-of-bounds write of a 32-byte descriptor past `descs[NUM_DESC]` into the container structure, overwriting `sdma_hdr`, `priv` and `txq` (and `qp`/`wqe`/`ss` or a `list_head` in the verbs and user_sdma containers), which then serve as write targets and list-manipulation operands.\nA:H - The reporter reproduced an immediate general protection fault in `hfi1_ipoib_build_ib_tx_headers()` from the corrupted `sdma_hdr`, and the NULLed `txq`/`priv` guarantee a NULL dereference in the completion path \u2014 a repeatable kernel panic from an unprivileged syscall."

This matches the AV:L scoring of the directly analogous `rtl8187_stop()` teardown UAF (CVE-2025-38604).\nAC:L - The attacker controls both sides of the race: Wi-Fi/BT-coex activity keeps C2H events and RA reports flowing so `schedule_work(\u0026priv-\u003ec2hcmd_work)` fires continuously, and the attacker chooses the exact moment to trigger the stop/unbind, so the window can be hit repeatedly until won.\nPR:L - An ordinary local user in a normal desktop/embedded session can reach the teardown path via logind-mediated suspend or rfkill, and no capability is needed to generate the Wi-Fi traffic that keeps the work queued; consistent with PR:L used across the driver-teardown UAF class.\nUI:N - The attacker performs both the traffic generation and the interface stop themselves; no separate victim has to open a file, mount anything, or take any action.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The freed `rtl8xxxu_priv` slab object can be reclaimed and groomed by the attacker, and the work callback reads through it (`priv-\u003efops`, `priv-\u003eudev-\u003edev`, `priv-\u003ec2hcmd_queue`), yielding a use-after-free read primitive that can disclose arbitrary kernel memory.\nI:H - The stale work item writes into the freed object (skb dequeue/list manipulation on `c2hcmd_queue`, updates to `priv-\u003era_report` and `priv-\u003ebt_coex`), and the workqueue core manipulates the freed embedded `work_struct`, giving a controlled-write primitive on reclaimed heap memory that is leverageable for control-flow hijack.\nA:H - Even unexploited, the use-after-free reliably produces a kernel oops or panic when the work runs against freed memory, and it can be retriggered on every device stop."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix deadlock while reading mqd from debugfs
An errant disk backup on my desktop got into debugfs and triggered the
following deadlock scenario in the amdgpu debugfs files. The machine
also hard-resets immediately after those lines are printed (although I
wasn't able to reproduce that part when reading by hand):

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: mediatek: mt7622-apmixedsys: Fix an error handling path in clk_mt8135_apmixed_probe()
'clk_data' is allocated with mtk_devm_alloc_clk_data(). So calling
mtk_free_clk_data() explicitly in the remove function would lead to a
double-free.
Remove the redundant call.

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: zynq: Prevent null pointer dereference caused by kmalloc failure
The kmalloc() in zynq_clk_setup() will return null if the
physical memory has run out. As a result, if we use snprintf()
to write data to the null address, the null pointer dereference
bug will happen.
This patch uses a stack variable to replace the kmalloc().

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: usbtv: Remove useless locks in usbtv_video_free()
Remove locks calls in usbtv_video_free() because
are useless and may led to a deadlock as reported here:
https://syzkaller.appspot.com/x/bisect.txt?x=166dc872180000
Also remove usbtv_stop() call since it will be called when
unregistering the device.
Before 'c838530d230b' this issue would only be noticed if you
disconnect while streaming and now it is noticeable even when
disconnecting while not streaming.

Summary
In the Linux kernel, the following vulnerability has been resolved:
md/md-bitmap: fix incorrect usage for sb_index
Commit d7038f951828 ("md-bitmap: don't use ->index for pages backing the
bitmap file") removed page->index from bitmap code, but left wrong code
logic for clustered-md. current code never set slot offset for cluster
nodes, will sometimes cause crash in clustered env.
Call trace (partly):

Summary
In the Linux kernel, the following vulnerability has been resolved:
pstore: inode: Only d_invalidate() is needed
Unloading a modular pstore backend with records in pstorefs would
trigger the dput() double-drop warning:
WARNING: CPU: 0 PID: 2569 at fs/dcache.c:762 dput.part.0+0x3f3/0x410
Using the combo of d_drop()/dput() (as mentioned in
Documentation/filesystems/vfs.rst) isn't the right approach here, and
leads to the reference counting problem seen above. Use d_invalidate()
and update the code to not bother checking for error codes that can
never happen.

"value": "AV:L - The vulnerability lives in the pstorefs VFS layer (fs/pstore/inode.c) and is reached only through local interfaces \u2014 an open file descriptor on a pstorefs record plus pstore backend teardown (module removal, driver unbind, or MTD device-removal notifier). No network or adjacent-network path exists.\nAC:L - The double-drop is deterministic, not a race: every record belonging to the unregistering backend takes the buggy path unconditionally, and keeping a record file open across teardown is fully under the attacker\u0027s control. No unpredictable memory layout or victim state is required to reach the underflow.\nPR:L - Consistent with this repo\u0027s scoring of driver-removal/rmmod-triggered UAFs, a local unprivileged process supplies the decisive half of the exploit \u2014 holding the fd, then driving slab reclaim of the freed pstore_private/dentry and consuming the primitives via read()/close(); backend unregistration also occurs on non-rmmod paths such as mtdpstore_notify_remove() and platform-driver removal during normal system operation.\nUI:N - No victim action is needed \u2014 the attacker performs the file open, the backend teardown, and the subsequent read()/close() that dereference the freed objects. Nothing requires a second user to interact with the system.\nS:U - The corruption is confined to kernel dcache and slab objects within the same kernel security authority; there is no VM, IOMMU, or sandbox boundary crossed. This is standard in-kernel memory corruption.\nC:H - The premature dentry kill evicts the inode and frees pstore_private/pstore_record/record-\u003ebuf while an open file still points at them via seq_file-\u003eprivate, so pstore_file_read() calls simple_read_from_buffer() with a freed, reclaimable source pointer and length \u2014 a controllable arbitrary kernel-memory read into userspace.\nI:H - The dentry refcount underflow frees the dentry while a file descriptor still holds it, so the later fput()/path_put()/dput() performs lockref decrements and d_child/d_subdirs list manipulation on reclaimed slab memory, yielding a write primitive suitable for heap-spray exploitation.\nA:H - At minimum the bug triggers WARNING at fs/dcache.c:762, which is fatal on the panic_on_warn configurations common in Android, hardened, and cloud kernels; with an open record file it produces a genuine dcache/slab use-after-free that reliably oopses or panics the kernel."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: Fix the lifetime of the bo cursor memory
The cleanup can be dispatched while the atomic update is still active,
which means that the memory acquired in the atomic update needs to
not be invalidated by the cleanup. The buffer objects in vmw_plane_state
instead of using the builtin map_and_cache were trying to handle
the lifetime of the mapped memory themselves, leading to crashes.
Use the map_and_cache instead of trying to manage the lifetime of the
buffer objects held by the vmw_plane_state.
Fixes kernel oops'es in IGT's kms_cursor_legacy forked-bo.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ovl: relax WARN_ON in ovl_verify_area()
syzbot hit an assertion in copy up data loop which looks like it is
the result of a lower file whose size is being changed underneath
overlayfs.
This type of use case is documented to cause undefined behavior, so
returning EIO error for the copy up makes sense, but it should not be
causing a WARN_ON assertion.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86, relocs: Ignore relocations in .notes section
When building with CONFIG_XEN_PV=y, .text symbols are emitted into
the .notes section so that Xen can find the "startup_xen" entry point.
This information is used prior to booting the kernel, so relocations
are not useful. In fact, performing relocations against the .notes
section means that the KASLR base is exposed since /sys/kernel/notes
is world-readable.
To avoid leaking the KASLR base without breaking unprivileged tools that
are expecting to read /sys/kernel/notes, skip performing relocations in
the .notes section. The values readable in .notes are then identical to
those found in System.map.

Summary
In the Linux kernel, the following vulnerability has been resolved:
l2tp: pass correct message length to ip6_append_data
l2tp_ip6_sendmsg needs to avoid accounting for the transport header
twice when splicing more data into an already partially-occupied skbuff.
To manage this, we check whether the skbuff contains data using
skb_queue_empty when deciding how much data to append using
ip6_append_data.
However, the code which performed the calculation was incorrect:
ulen = len + skb_queue_empty(&sk->sk_write_queue) ? transhdrlen : 0;
...due to C operator precedence, this ends up setting ulen to
transhdrlen for messages with a non-zero length, which results in
corrupted packets on the wire.
Add parentheses to correct the calculation in line with the original
intent.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: b43: Stop/wake correct queue in DMA Tx path when QoS is disabled
When QoS is disabled, the queue priority value will not map to the correct
ieee80211 queue since there is only one queue. Stop/wake queue 0 when QoS
is disabled to prevent trying to stop/wake a non-existent queue and failing
to stop/wake the actual queue instantiated.
Log of issue before change (with kernel parameter qos=0):

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: Always flush async #PF workqueue when vCPU is being destroyed
Always flush the per-vCPU async #PF workqueue when a vCPU is clearing its
completion queue, e.g. when a VM and all its vCPUs is being destroyed.
KVM must ensure that none of its workqueue callbacks is running when the
last reference to the KVM _module_ is put. Gifting a reference to the
associated VM prevents the workqueue callback from dereferencing freed
vCPU/VM memory, but does not prevent the KVM module from being unloaded
before the callback completes.
Drop the misguided VM refcount gifting, as calling kvm_put_kvm() from
async_pf_execute() if kvm_put_kvm() flushes the async #PF workqueue will
result in deadlock. async_pf_execute() can't return until kvm_put_kvm()
finishes, and kvm_put_kvm() can't return until async_pf_execute() finishes:

If kvm_clear_async_pf_completion_queue() actually flushes the workqueue,
then there's no need to gift async_pf_execute() a reference because all
invocations of async_pf_execute() will be forced to complete before the
vCPU and its VM are destroyed/freed. And that in turn fixes the module
unloading bug as __fput() won't do module_put() on the last vCPU reference
until the vCPU has been freed, e.g. if closing the vCPU file also puts the
last reference to the KVM module.
Note that kvm_check_async_pf_completion() may also take the work item off
the completion queue and so also needs to flush the work queue, as the
work will not be seen by kvm_clear_async_pf_completion_queue(). Waiting
on the workqueue could theoretically delay a vCPU due to waiting for the
work to complete, but that's a very, very small chance, and likely a very
small delay. kvm_arch_async_page_present_queued() unconditionally makes a
new request, i.e. will effectively delay entering the guest, so the
remaining work is really just:
trace_kvm_async_pf_completed(addr, cr2_or_gpa);
__kvm_vcpu_wake_up(vcpu);
mmput(mm);
and mmput() can't drop the last reference to the page tables if the vCPU is
still alive, i.e. the vCPU won't get stuck tearing down page tables.
Add a helper to do the flushing, specifically to deal with "wakeup all"
work items, as they aren't actually work items, i.e. are never placed in a
workqueue. Trying to flush a bogus workqueue entry rightly makes
__flush_work() complain (kudos to whoever added that sanity check).

Gifting a reference to the\nassociated VM prevents the workqueue callback from dereferencing freed\nvCPU/VM memory, but does not prevent the KVM module from being unloaded\nbefore the callback completes.\n\nDrop the misguided VM refcount gifting, as calling kvm_put_kvm() from\nasync_pf_execute() if kvm_put_kvm() flushes the async #PF workqueue will\nresult in deadlock. async_pf_execute() can\u0027t return until kvm_put_kvm()\nfinishes, and kvm_put_kvm() can\u0027t return until async_pf_execute() finishes:\n\n WARNING: CPU: 8 PID: 251 at virt/kvm/kvm_main.c:1435 kvm_put_kvm+0x2d/0x320 [kvm]\n Modules linked in: vhost_net vhost vhost_iotlb tap kvm_intel kvm irqbypass\n CPU: 8 PID: 251 Comm: kworker/8:1 Tainted: G W 6.6.0-rc1-e7af8d17224a-x86/gmem-vm #119\n Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015\n Workqueue: events async_pf_execute [kvm]\n RIP: 0010:kvm_put_kvm+0x2d/0x320 [kvm]\n Call Trace:\n \u003cTASK\u003e\n async_pf_execute+0x198/0x260 [kvm]\n process_one_work+0x145/0x2d0\n worker_thread+0x27e/0x3a0\n kthread+0xba/0xe0\n ret_from_fork+0x2d/0x50\n ret_from_fork_asm+0x11/0x20\n \u003c/TASK\u003e\n ---[ end trace 0000000000000000 ]---\n INFO: task kworker/8:1:251 blocked for more than 120 seconds.\n Tainted: G W 6.6.0-rc1-e7af8d17224a-x86/gmem-vm #119\n \"echo 0 \u003e /proc/sys/kernel/hung_task_timeout_secs\" disables this message.\n task:kworker/8:1 state:D stack:0 pid:251 ppid:2 flags:0x00004000\n Workqueue: events async_pf_execute [kvm]\n Call Trace:\n \u003cTASK\u003e\n __schedule+0x33f/0xa40\n schedule+0x53/0xc0\n schedule_timeout+0x12a/0x140\n __wait_for_common+0x8d/0x1d0\n __flush_work.isra.0+0x19f/0x2c0\n kvm_clear_async_pf_completion_queue+0x129/0x190 [kvm]\n kvm_arch_destroy_vm+0x78/0x1b0 [kvm]\n kvm_put_kvm+0x1c1/0x320 [kvm]\n async_pf_execute+0x198/0x260 [kvm]\n process_one_work+0x145/0x2d0\n worker_thread+0x27e/0x3a0\n kthread+0xba/0xe0\n ret_from_fork+0x2d/0x50\n ret_from_fork_asm+0x11/0x20\n \u003c/TASK\u003e\n\nIf kvm_clear_async_pf_completion_queue() actually flushes the workqueue,\nthen there\u0027s no need to gift async_pf_execute() a reference because all\ninvocations of async_pf_execute() will be forced to complete before the\nvCPU and its VM are destroyed/freed. And that in turn fixes the module\nunloading bug as __fput() won\u0027t do module_put() on the last vCPU reference\nuntil the vCPU has been freed, e.g. if closing the vCPU file also puts the\nlast reference to the KVM module.\n\nNote that kvm_check_async_pf_completion() may also take the work item off\nthe completion queue and so also needs to flush the work queue, as the\nwork will not be seen by kvm_clear_async_pf_completion_queue(). Waiting\non the workqueue could theoretically delay a vCPU due to waiting for the\nwork to complete, but that\u0027s a very, very small chance, and likely a very\nsmall delay. kvm_arch_async_page_present_queued() unconditionally makes a\nnew request, i.e. will effectively delay entering the guest, so the\nremaining work is really just:\n\n trace_kvm_async_pf_completed(addr, cr2_or_gpa);\n\n __kvm_vcpu_wake_up(vcpu);\n\n mmput(mm);\n\nand mmput() can\u0027t drop the last reference to the page tables if the vCPU is\nstill alive, i.e. the vCPU won\u0027t get stuck tearing down page tables.\n\nAdd a helper to do the flushing, specifically to deal with \"wakeup all\"\nwork items, as they aren\u0027t actually work items, i.e. are never placed in a\nworkqueue. Trying to flush a bogus workqueue entry rightly makes\n__flush_work() complain (kudos to whoever added that sanity check).\n\nNote, commit 5f6de5cbebee (\"KVM: Prevent module exit until al\n---truncated---"

"value": "AV:L - The vulnerability is reached exclusively through `/dev/kvm` ioctls (`KVM_CREATE_VM`/`KVM_CREATE_VCPU`/`KVM_SET_USER_MEMORY_REGION`/`KVM _RUN`) plus `close()` of the vCPU fd, all of which require an account on the host; there is no network, adjacent-network, or remote-peer data path into `virt/kvm/async_pf.c`.\nAC:L - The attacker controls both sides of the window \u2014 `madvise(MADV_PAGEOUT)` on its own guest memslot guarantees `__gfn_to_pfn_memslot()` returns async, queueing up to `ASYNC_PF_PER_VCPU` (64) work items per vCPU that each sleep in `get_user_pages_remote()` for the whole swap-in latency, while `close()` of the vCPU fd drives `__fput()`\u2192`module_put()` at a moment of the attacker\u0027s choosing. Nothing depends on a memory layout or system state the attacker cannot influence, and the flaw is unconditional on x86 since `CONFIG_KVM_ASYNC_PF` is `select`ed by `CONFIG_KVM`.\nPR:L - No capability check exists anywhere on the path \u2014 `kvm_dev_ioctl(KVM_CREATE_VM)`, `kvm_setup_async_pf()`, and vCPU teardown are all reachable by any user holding an open `/dev/kvm`, which distros grant to the ordinary `kvm` group and container/CI images commonly expose world-writable. The entire unsafe state that constitutes the bug \u2014 KVM module code still executing after the last `module_put()` \u2014 is created with zero privileges, so PR:L is selected as the higher-severity option over PR:H.\nUI:N - No victim action such as mounting a filesystem, opening a device, or plugging in hardware is required; `kvm_clear_async_pf_completion_queue()` and the premature `module_put()` run automatically from `__fput()`/`kvm_destroy_vm()` when the attacker\u0027s own process exits.\nS:U - The stale work callback and the freed module text/`async_pf_cache` slab are both host-kernel resources, so the flaw and its impact stay within a single security authority \u2014 this is a host-internal module-lifetime bug, not a guest-to-host or IOMMU boundary escape.\nC:H - This is a use-after-free in which `process_one_work()` dispatches `worker-\u003ecurrent_func()` into a freed vmalloc module region and `async_pf_execute()` continues touching `struct kvm_async_pf` after `kmem_cache_destroy()` has released the slab; controlling the reallocated module-alloc/vmalloc contents yields kernel-mode execution and thus arbitrary kernel memory disclosure.\nI:H - The stale callback writes through the freed object (`list_add_tail(\u0026apf-\u003elink, ...)`, `apf-\u003evcpu = NULL`) into slab pages already returned to the allocator and reissued to other consumers, and executing a freed function pointer as kernel text is a direct control-flow hijack primitive \u2014 both are arbitrary-write class outcomes.\nA:H - Jumping into unmapped or repurposed vmalloc memory produces an immediate oops/panic, `kmem_cache_destroy()` on the still-populated `async_pf_cache` corrupts allocator state, and the same path drives full `kvm_destroy_vm()` teardown from a shared `system_wq` worker, which the commit\u0027s own trace shows wedging a kworker for more than 120 seconds."

Summary
In the Linux kernel, the following vulnerability has been resolved:
swiotlb: Fix double-allocation of slots due to broken alignment handling
Commit bbb73a103fbb ("swiotlb: fix a braino in the alignment check fix"),
which was a fix for commit 0eee5ae10256 ("swiotlb: fix slot alignment
checks"), causes a functional regression with vsock in a virtual machine
using bouncing via a restricted DMA SWIOTLB pool.
When virtio allocates the virtqueues for the vsock device using
dma_alloc_coherent(), the SWIOTLB search can return page-unaligned
allocations if 'area->index' was left unaligned by a previous allocation
from the buffer:
# Final address in brackets is the SWIOTLB address returned to the caller
| virtio-pci 0000:00:07.0: orig_addr 0x0 alloc_size 0x2000, iotlb_align_mask 0x800 stride 0x2: got slot 1645-1649/7168 (0x98326800)
| virtio-pci 0000:00:07.0: orig_addr 0x0 alloc_size 0x2000, iotlb_align_mask 0x800 stride 0x2: got slot 1649-1653/7168 (0x98328800)
| virtio-pci 0000:00:07.0: orig_addr 0x0 alloc_size 0x2000, iotlb_align_mask 0x800 stride 0x2: got slot 1653-1657/7168 (0x9832a800)
This ends badly (typically buffer corruption and/or a hang) because
swiotlb_alloc() is expecting a page-aligned allocation and so blindly
returns a pointer to the 'struct page' corresponding to the allocation,
therefore double-allocating the first half (2KiB slot) of the 4KiB page.
Fix the problem by treating the allocation alignment separately to any
additional alignment requirements from the device, using the maximum
of the two as the stride to search the buffer slots and taking care
to ensure a minimum of page-alignment for buffers larger than a page.
This also resolves swiotlb allocation failures occuring due to the
inclusion of ~PAGE_MASK in 'iotlb_align_mask' for large allocations and
resulting in alignment requirements exceeding swiotlb_max_mapping_size().

"value": "AV:L - The defect is in the core DMA bounce-buffer allocator (`kernel/dma/swiotlb.c`) and is driven by local DMA activity \u2014 `dma_alloc_coherent()`/`dma_map_page()` issued on behalf of a local process doing device or block/network I/O. There is no network-facing protocol handler parsing remote data on the path to `swiotlb_search_pool_area()`.\nAC:L - Triggering is deterministic and race-free: the attacker only needs `area-\u003eindex` left at an odd slot by any prior odd-sized bounce (routine for ordinary I/O) so the stride-2 search returns page-unaligned slots, and for the mapping path merely a buffer whose page offset is \u003e= 2048. Both the restricted-DMA-pool `swiotlb_alloc()` path and the generic `iommu_dma_map_page()`/untrusted-device and arm64 kmalloc-bounce paths are affected, so this is not confined to a rare config.\nPR:L - No capability, admin right, or `CAP_SYS_*` check exists anywhere between userspace and `swiotlb_find_slots()`; any unprivileged process can consume and release swiotlb slots and force coherent DMA allocations through normal file, socket, and device-node I/O. Local access is required, so basic user privileges rather than none.\nUI:N - The attacking process performs the entire allocate/free/map sequence itself. No victim action such as mounting a filesystem, opening a file, or plugging in hardware is required.\nS:U - The corrupted and over-exposed memory is host kernel memory \u2014 swiotlb slots and DMA-coherent buffers \u2014 managed by the same kernel security authority as the vulnerable allocator. Even the granule-misaligned IOMMU mapping stays inside the swiotlb region, so no VM, hypervisor, or sandbox boundary is crossed.\nC:H - `swiotlb_alloc()` returns `pfn_to_page(PFN_DOWN(tlb_addr))` for an unaligned slot, so a caller receives a page whose first 2 KiB is another live allocation\u0027s DMA data, and the mis-rounded `swiotlb_free()` recycles in-use slots so in-flight device DMA lands in memory handed to a different owner. On the `iommu_dma_map_page()` path `__iommu_dma_map()` maps `phys - iova_off`, granting a device \u2014 including an untrusted external PCIe/Thunderbolt device \u2014 DMA read visibility into an adjacent bounce buffer holding unrelated in-flight I/O.\nI:H - Two independent `dma_alloc_coherent()` consumers end up writing the same physical page, so device DMA and driver writes clobber the other allocation\u0027s contents \u2014 including virtio virtqueue descriptor tables holding physical addresses and lengths, which is a controllable kernel memory corruption primitive. The same misaligned IOMMU window is mapped writable for `DMA_FROM_DEVICE`/`DMA_BIDIRECTIONAL`, letting a device write outside its intended buffer.\nA:H - The commit message states the double-allocation \"ends badly (typically buffer corruption and/or a hang)\", and corrupted virtqueue rings or DMA descriptors readily produce oops/panic. Additionally, the bogus `~PAGE_MASK` alignment requirement exceeds `swiotlb_max_mapping_size()` and causes persistent \"swiotlb buffer is full\" mapping failures, breaking device I/O."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: wilc1000: do not realloc workqueue everytime an interface is added
Commit 09ed8bfc5215 ("wilc1000: Rename workqueue from "WILC_wq" to
"NETDEV-wq"") moved workqueue creation in wilc_netdev_ifc_init in order to
set the interface name in the workqueue name. However, while the driver
needs only one workqueue, the wilc_netdev_ifc_init is called each time we
add an interface over a phy, which in turns overwrite the workqueue with a
new one. This can be observed with the following commands:
for i in $(seq 0 10)
do
iw phy phy0 interface add wlan1 type managed
iw dev wlan1 del
done
ps -eo pid,comm|grep wlan
39 kworker/R-wlan0
98 kworker/R-wlan1
102 kworker/R-wlan1
105 kworker/R-wlan1
108 kworker/R-wlan1
111 kworker/R-wlan1
114 kworker/R-wlan1
117 kworker/R-wlan1
120 kworker/R-wlan1
123 kworker/R-wlan1
126 kworker/R-wlan1
129 kworker/R-wlan1
Fix this leakage by putting back hif_workqueue allocation in
wilc_cfg80211_init. Regarding the workqueue name, it is indeed relevant to
set it lowercase, however it is not attached to a specific netdev, so
enforcing netdev name in the name is not so relevant. Still, enrich the
name with the wiphy name to make it clear which phy is using the workqueue.

However, while the driver\nneeds only one workqueue, the wilc_netdev_ifc_init is called each time we\nadd an interface over a phy, which in turns overwrite the workqueue with a\nnew one.

Regarding the workqueue name, it is indeed relevant to\nset it lowercase, however it is not attached to a specific netdev, so\nenforcing netdev name in the name is not so relevant. Still, enrich the\nname with the wiphy name to make it clear which phy is using the workqueue."

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfs: fix UAF in direct writes
In production we have been hitting the following warning consistently
------------[ cut here ]------------
refcount_t: underflow; use-after-free.
WARNING: CPU: 17 PID: 1800359 at lib/refcount.c:28 refcount_warn_saturate+0x9c/0xe0
Workqueue: nfsiod nfs_direct_write_schedule_work [nfs]
RIP: 0010:refcount_warn_saturate+0x9c/0xe0

This is because we're completing the nfs_direct_request twice in a row.
The source of this is when we have our commit requests to submit, we
process them and send them off, and then in the completion path for the
commit requests we have
if (nfs_commit_end(cinfo.mds))
nfs_direct_write_complete(dreq);
However since we're submitting asynchronous requests we sometimes have
one that completes before we submit the next one, so we end up calling
complete on the nfs_direct_request twice.
The only other place we use nfs_generic_commit_list() is in
__nfs_commit_inode, which wraps this call in a
nfs_commit_begin();
nfs_commit_end();
Which is a common pattern for this style of completion handling, one
that is also repeated in the direct code with get_dreq()/put_dreq()
calls around where we process events as well as in the completion paths.
Fix this by using the same pattern for the commit requests.
Before with my 200 node rocksdb stress running this warning would pop
every 10ish minutes. With my patch the stress test has been running for
several hours without popping.

Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to truncate meta inode pages forcely
Below race case can cause data corruption:
Thread A GC thread
- gc_data_segment
- ra_data_block
- locked meta_inode page
- f2fs_inplace_write_data
- invalidate_mapping_pages
: fail to invalidate meta_inode page
due to lock failure or dirty|writeback
status
- f2fs_submit_page_bio
: write last dirty data to old blkaddr
- move_data_block
- load old data from meta_inode page
- f2fs_submit_page_write
: write old data to new blkaddr
Because invalidate_mapping_pages() will skip invalidating page which
has unclear status including locked, dirty, writeback and so on, so
we need to use truncate_inode_pages_range() instead of
invalidate_mapping_pages() to make sure meta_inode page will be dropped.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: fix NULL checks for adev->dm.dc in amdgpu_dm_fini()
Since 'adev->dm.dc' in amdgpu_dm_fini() might turn out to be NULL
before the call to dc_enable_dmub_notifications(), check
beforehand to ensure there will not be a possible NULL-ptr-deref
there.
Also, since commit 1e88eb1b2c25 ("drm/amd/display: Drop
CONFIG_DRM_AMD_DC_HDCP") there are two separate checks for NULL in
'adev->dm.dc' before dc_deinit_callbacks() and dc_dmub_srv_destroy().
Clean up by combining them all under one 'if'.
Found by Linux Verification Center (linuxtesting.org) with static
analysis tool SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: mana: Fix Rx DMA datasize and skb_over_panic
mana_get_rxbuf_cfg() aligns the RX buffer's DMA datasize to be
multiple of 64. So a packet slightly bigger than mtu+14, say 1536,
can be received and cause skb_over_panic.
Sample dmesg:
[ 5325.237162] skbuff: skb_over_panic: text:ffffffffc043277a len:1536 put:1536 head:ff1100018b517000 data:ff1100018b517100 tail:0x700 end:0x6ea dev:<NULL>
[ 5325.243689] ------------[ cut here ]------------

[ 5325.326328] net_rx_action+0x12e/0x280
As discussed internally, this alignment is not necessary. To fix
this bug, remove it from the code. So oversized packets will be
marked as CQE_RX_TRUNCATED by NIC, and dropped.

No race, no memory-layout grooming, and no state outside the attacker\u0027s control is involved.\nPR:N - No authentication or credentials of any kind are needed; the panic occurs in mana_build_skb() before eth_type_trans() and before netfilter, so the frame need not even be addressed to a listening service or survive a firewall rule. Any unauthenticated party able to send a frame to the interface triggers it.\nUI:N - Triggering requires only that the victim\u0027s interface be up and receiving; the panic happens in softirq context during normal packet reception with no action by any local user or administrator.\nS:U - The vulnerable code and the impacted resource are both the host kernel \u2014 a standard in-kernel crash with no crossing of a VM, IOMMU, or sandbox security authority.\nC:N - No data is disclosed to the attacker: the overlong DMA writes the attacker\u0027s own packet bytes into the buffer\u0027s skb_shared_info scratch area within the same allocation, and skb_over_panic() aborts immediately, so no kernel memory is read back or leaked over the wire.\nI:N - The excess DMA stays inside the allocated page/fragment, targets a region that is not a live object at DMA time and is re-zeroed by napi_build_skb(), and every packet reaching it hits the unconditional BUG() in the same call path \u2014 so no adjacent object is corrupted and no write primitive is obtained.\nA:H - skb_put() detects tail \u003e end and calls skb_over_panic() \u2192 BUG() from within NAPI/softirq context, producing a fatal exception in interrupt and a full kernel panic. A single crafted packet takes the machine down, and it can be repeated at will against every affected Azure VM."

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3-am62: fix module unload/reload behavior
As runtime PM is enabled, the module can be runtime
suspended when .remove() is called.
Do a pm_runtime_get_sync() to make sure module is active
before doing any register operations.
Doing a pm_runtime_put_sync() should disable the refclk
so no need to disable it again.
Fixes the below warning at module removel.
[ 39.705310] ------------[ cut here ]------------
[ 39.710004] clk:162:3 already disabled
[ 39.713941] WARNING: CPU: 0 PID: 921 at drivers/clk/clk.c:1090 clk_core_disable+0xb0/0xb8
We called of_platform_populate() in .probe() so call the
cleanup function of_platform_depopulate() in .remove().
Get rid of the now unnnecessary dwc3_ti_remove_core().
Without this, module re-load doesn't work properly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Fix double free in SMC transport cleanup path
When the generic SCMI code tears down a channel, it calls the chan_free
callback function, defined by each transport. Since multiple protocols
might share the same transport_info member, chan_free() might want to
clean up the same member multiple times within the given SCMI transport
implementation. In this case, it is SMC transport. This will lead to a NULL
pointer dereference at the second time:
| scmi_protocol scmi_dev.1: Enabled polling mode TX channel - prot_id:16
| arm-scmi firmware:scmi: SCMI Notifications - Core Enabled.
| arm-scmi firmware:scmi: unable to communicate with SCMI

Simply check for the struct pointer being NULL before trying to access
its members, to avoid this situation.
This was found when a transport doesn't really work (for instance no SMC
service), the probe routines then tries to clean up, and triggers a crash.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xhci: handle isoc Babble and Buffer Overrun events properly
xHCI 4.9 explicitly forbids assuming that the xHC has released its
ownership of a multi-TRB TD when it reports an error on one of the
early TRBs. Yet the driver makes such assumption and releases the TD,
allowing the remaining TRBs to be freed or overwritten by new TDs.
The xHC should also report completion of the final TRB due to its IOC
flag being set by us, regardless of prior errors. This event cannot
be recognized if the TD has already been freed earlier, resulting in
"Transfer event TRB DMA ptr not part of current TD" error message.
Fix this by reusing the logic for processing isoc Transaction Errors.
This also handles hosts which fail to report the final completion.
Fix transfer length reporting on Babble errors. They may be caused by
device malfunction, no guarantee that the buffer has been filled.

Consistent with the in-tree scoring of the analogous xhci isoc ring bugs (CVE-2025-37882, CVE-2025-22022).\nAC:L - `usb_submit_urb()` only bounds isoc frame lengths from above, so short isoc IN frames reliably provoke Isoch Buffer Overrun, and multi-TRB isoc TDs are the normal case for high-bandwidth SuperSpeed streams; the condition can be re-triggered every service interval. A malicious attached device can force babble deterministically.\nPR:L - Requires only an unprivileged local account with access to an isochronous USB endpoint (video/audio group membership or console-seat uaccess ACLs on /dev/bus/usb, /dev/video*, /dev/snd/*). No root or CAP_SYS_ADMIN is needed.\nUI:N - Once an isochronous-capable device is present, the attacker submits the URBs themselves; no victim action is required to trigger the premature TD giveback.\nS:U - The corruption and its impact are confined to the kernel\u0027s own memory and the xHCI host controller driver \u2014 the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The TD is released while the xHC still owns its remaining TRBs, so the controller keeps DMAing into a buffer that was given back and may be reallocated to another subsystem; that reallocated content is then reported back through the URB, and stale TRBs let the HC read reused memory \u2014 an arbitrary kernel-memory disclosure primitive.\nI:H - This is a use-after-free write: the xHC DMAs device-supplied data into freed/reallocated kernel memory, and freed TRB slots overwritten by new TDs let the controller act on torn TRBs with mismatched addresses and lengths, giving a corruption primitive leveragable for control-flow hijack.\nA:H - The missing final-TRB event produces \"Transfer event TRB DMA ptr not part of current TD\" and `-ESHUTDOWN`, desynchronizing driver and hardware and reaching `xhci_hc_died()`/`usb_hc_died()`, which kills every URB and all devices on the controller; the DMA-into-freed-memory and IOMMU-fault paths additionally cause kernel crashes."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix slab-out-of-bounds in smb_strndup_from_utf16()
If ->NameOffset of smb2_create_req is smaller than Buffer offset of
smb2_create_req, slab-out-of-bounds read can happen from smb2_open.
This patch set the minimum value of the name offset to the buffer offset
to validate name length of smb2_create_req().

Summary
In the Linux kernel, the following vulnerability has been resolved:
leds: trigger: netdev: Fix kernel panic on interface rename trig notify
Commit d5e01266e7f5 ("leds: trigger: netdev: add additional specific link
speed mode") in the various changes, reworked the way to set the LINKUP
mode in commit cee4bd16c319 ("leds: trigger: netdev: Recheck
NETDEV_LED_MODE_LINKUP on dev rename") and moved it to a generic function.
This changed the logic where, in the previous implementation the dev
from the trigger event was used to check if the carrier was ok, but in
the new implementation with the generic function, the dev in
trigger_data is used instead.
This is problematic and cause a possible kernel panic due to the fact
that the dev in the trigger_data still reference the old one as the
new one (passed from the trigger event) still has to be hold and saved
in the trigger_data struct (done in the NETDEV_REGISTER case).
On calling of get_device_state(), an invalid net_dev is used and this
cause a kernel panic.
To handle this correctly, move the call to get_device_state() after the
new net_dev is correctly set in trigger_data (in the NETDEV_REGISTER
case) and correctly parse the new dev.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: avoid allocating blocks from corrupted group in ext4_mb_try_best_found()
Determine if the group block bitmap is corrupted before using ac_b_ex in
ext4_mb_try_best_found() to avoid allocating blocks from a group with a
corrupted block bitmap in the following concurrency and making the
situation worse.
ext4_mb_regular_allocator
ext4_lock_group(sb, group)
ext4_mb_good_group
// check if the group bbitmap is corrupted
ext4_mb_complex_scan_group
// Scan group gets ac_b_ex but doesn't use it
ext4_unlock_group(sb, group)
ext4_mark_group_bitmap_corrupted(group)
// The block bitmap was corrupted during
// the group unlock gap.
ext4_mb_try_best_found
ext4_lock_group(ac->ac_sb, group)
ext4_mb_use_best_found
mb_mark_used
// Allocating blocks in block bitmap corrupted group

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: savage: Error out if pixclock equals zero
The userspace program could pass any values to the driver through
ioctl() interface. If the driver doesn't check the value of pixclock,
it may cause divide-by-zero error.
Although pixclock is checked in savagefb_decode_var(), but it is not
checked properly in savagefb_probe(). Fix this by checking whether
pixclock is zero in the function savagefb_check_var() before
info->var.pixclock is used as the divisor.
This is similar to CVE-2022-3061 in i740fb which was fixed by
commit 15cf0b8.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: roles: fix NULL pointer issue when put module's reference
In current design, usb role class driver will get usb_role_switch parent's
module reference after the user get usb_role_switch device and put the
reference after the user put the usb_role_switch device. However, the
parent device of usb_role_switch may be removed before the user put the
usb_role_switch. If so, then, NULL pointer issue will be met when the user
put the parent module's reference.
This will save the module pointer in structure of usb_role_switch. Then,
we don't need to find module by iterating long relations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
erofs: fix lz4 inplace decompression
Currently EROFS can map another compressed buffer for inplace
decompression, that was used to handle the cases that some pages of
compressed data are actually not in-place I/O.
However, like most simple LZ77 algorithms, LZ4 expects the compressed
data is arranged at the end of the decompressed buffer and it
explicitly uses memmove() to handle overlapping:
__________________________________________________________
|_ direction of decompression --> ____ |_ compressed data _|
Although EROFS arranges compressed data like this, it typically maps two
individual virtual buffers so the relative order is uncertain.
Previously, it was hardly observed since LZ4 only uses memmove() for
short overlapped literals and x86/arm64 memmove implementations seem to
completely cover it up and they don't have this issue. Juhyung reported
that EROFS data corruption can be found on a new Intel x86 processor.
After some analysis, it seems that recent x86 processors with the new
FSRM feature expose this issue with "rep movsb".
Let's strictly use the decompressed buffer for lz4 inplace
decompression for now. Later, as an useful improvement, we could try
to tie up these two buffers together in the correct order.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powercap: intel_rapl: Fix a NULL pointer dereference
A NULL pointer dereference is triggered when probing the MMIO RAPL
driver on platforms with CPU ID not listed in intel_rapl_common CPU
model list.
This is because the intel_rapl_common module still probes on such
platforms even if 'defaults_msr' is not set after commit 1488ac990ac8
("powercap: intel_rapl: Allow probing without CPUID match"). Thus the
MMIO RAPL rp->priv->defaults is NULL when registering to RAPL framework.
Fix the problem by adding sanity check to ensure rp->priv->rapl_defaults
is always valid.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_event: Fix handling of HCI_EV_IO_CAPA_REQUEST
If we received HCI_EV_IO_CAPA_REQUEST while
HCI_OP_READ_REMOTE_EXT_FEATURES is yet to be responded assume the remote
does support SSP since otherwise this event shouldn't be generated.

Per kernel scoring convention Bluetooth is Adjacent.\nAC:L - The attacker controls its own controller\u0027s LMP timing and simply starts SSP immediately upon connection-complete, which reliably beats the host\u0027s extra Read Remote Extended Features HCI command plus LMP round trip; the attempt can also be repeated without limit.\nPR:N - HCI_EV_IO_CAPA_REQUEST and HCI_EV_SIMPLE_PAIR_COMPLETE are handled during the pre-bonding pairing phase, before any credentials or link key exist, and the guard is hit before even the HCI_MGMT/HCI_BONDABLE policy checks. No privileges on the target are required.\nUI:N - Reaching the code needs only an ACL connection to a connectable or accept-listed host, which is the default steady state for embedded, automotive, audio, kiosk and previously-paired deployments. No victim action is needed to trigger the event sequence.\nS:U - The corrupted state (hci_conn reference count and connection lifetime) lives entirely within the kernel\u0027s own security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:H - The unbalanced hci_conn_drop() reintroduces a reference-count underflow (CWE-911) on a kernel object, which can drive the connection to teardown while pairing-state-machine work still references it \u2014 a use-after-free class defect whose reclaimed memory can be leveraged for kernel information disclosure.\nI:H - The same refcount underflow lets an attacker-controlled peer desynchronize hci_conn lifetime accounting, and a freed-then-reused hci_conn under remote-influenced heap grooming yields write/control-flow primitives; the guidance treats use-after-free as High integrity impact.\nA:H - A remote peer can reliably stall SSP so pairing never completes, trigger WARN_ON(refcnt \u003c 0) in hci_conn_timeout() (a panic on panic_on_warn builds such as Android and hardened distro kernels), abort a live ACL link prematurely, or leak connections that never time out and exhaust the controller\u0027s ACL slots."

Summary
In the Linux kernel, the following vulnerability has been resolved:
soc: fsl: qbman: Always disable interrupts when taking cgr_lock
smp_call_function_single disables IRQs when executing the callback. To
prevent deadlocks, we must disable IRQs when taking cgr_lock elsewhere.
This is already done by qman_update_cgr and qman_delete_cgr; fix the
other lockers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: dev-replace: properly validate device names
There's a syzbot report that device name buffers passed to device
replace are not properly checked for string termination which could lead
to a read out of bounds in getname_kernel().
Add a helper that validates both source and target device name buffers.
For devid as the source initialize the buffer to empty string in case
something tries to read it later.
This was originally analyzed and fixed in a different way by Edward Adam
Davis (see links).

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."

[Analyze]
Task A set disconnect_flag = !0, which resulted in Task B's condition being met
and releasing mp, leading to this issue.
[Fix]
Place the disconnect_flag assignment operation after all code in pvr2_context_disconnect()
to avoid this issue.

"value": "AV:N - The bug is triggered purely by an inbound Ethernet frame arriving on the vmxnet3 vNIC and being processed in the NAPI receive path (`vmxnet3_rq_rx_complete` \u2192 `vmxnet3_process_xdp`); any remote host that can route a \u003e946-byte packet to the VM reaches the vulnerable code. No local access to the target is needed.\nAC:L - The attacker fully controls the only condition that matters \u2014 packet size \u2014 and any ordinary frame above ~946 bytes (a single ICMP echo or one TCP segment of a bulk transfer) deterministically hits `xdp-\u003edata_end \u003e xdp_data_hard_end(xdp)`. There is no race, no memory-layout dependency, and no state the attacker cannot influence.\nPR:N - The vulnerable code runs on packet receive before any authentication, authorization, or socket demultiplexing; the attacker needs no account or credentials on the target, only the ability to send a frame to its vmxnet3 interface.\nUI:N - Processing happens automatically in the driver\u0027s NAPI poll routine as soon as the packet is received; no action by any user or administrator on the victim system is required.\nS:U - The WARN, the packet drop, and any resulting panic are all confined to the kernel of the host running the vmxnet3 driver \u2014 the same security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:N - The under-sized `frame_sz` only shrinks the region XDP is permitted to touch, so no out-of-bounds read occurs and `xdp_convert_buff_to_frame()` aborts before any data is forwarded. Nothing is returned to or readable by the attacker (the on-the-wire data leak came from the *later* `xdp_prepare_buff()` change, not from the pre-fix code).\nI:N - No out-of-bounds or overlapping write is possible \u2014 `vmxnet3_build_skb()` uses `PAGE_SIZE`, `bpf_xdp_adjust_tail()` is made more restrictive rather than less, and the error paths recycle the page exactly once with no double-free or state corruption.\nA:H - Every oversized frame executes a non-ratelimited `WARN(1, ...)` with a full stack dump from softirq context, letting an unauthenticated remote attacker flood the console/log at line rate (soft lockups, RCU stalls) and drop all XDP_REDIRECT/XDP_TX traffic; on kernels with `panic_on_warn=1` a single packet causes an immediate kernel panic."

Summary
In the Linux kernel, the following vulnerability has been resolved:
vfio/fsl-mc: Block calling interrupt handler without trigger
The eventfd_ctx trigger pointer of the vfio_fsl_mc_irq object is
initially NULL and may become NULL if the user sets the trigger
eventfd to -1. The interrupt handler itself is guaranteed that
trigger is always valid between request_irq() and free_irq(), but
the loopback testing mechanisms to invoke the handler function
need to test the trigger. The triggering and setting ioctl paths
both make use of igate and are therefore mutually exclusive.
The vfio-fsl-mc driver does not make use of irqfds, nor does it
support any sort of masking operations, therefore unlike vfio-pci
and vfio-platform, the flow can remain essentially unchanged.

Summary
In the Linux kernel, the following vulnerability has been resolved:
kprobes/x86: Use copy_from_kernel_nofault() to read from unsafe address
Read from an unsafe address with copy_from_kernel_nofault() in
arch_adjust_kprobe_addr() because this function is used before checking
the address is in text or not. Syzcaller bot found a bug and reported
the case if user specifies inaccessible data area,
arch_adjust_kprobe_addr() will cause a kernel panic.

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/dasd: fix double module refcount decrement
Once the discipline is associated with the device, deleting the device
takes care of decrementing the module's refcount. Doing it manually on
this error path causes refcount to artificially decrease on each error
while it should just stay the same.

CWE
- CWE-416 - Use After Free
Summary
A flaw was found in the ATA over Ethernet (AoE) driver in the Linux kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on `struct net_device`, and a use-after-free can be triggered by racing between the free on the struct and the access through the `skbtxq` global queue. This could lead to a denial of service condition or potential code execution.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSv4.2: fix nfs4_listxattr kernel BUG at mm/usercopy.c:102
A call to listxattr() with a buffer size = 0 returns the actual
size of the buffer needed for a subsequent call. When size > 0,
nfs4_listxattr() does not return an error because either
generic_listxattr() or nfs4_listxattr_nfs4_label() consumes
exactly all the bytes then size is 0 when calling
nfs4_listxattr_nfs4_user() which then triggers the following
kernel BUG:

Issue is reproduced when generic_listxattr() returns 'system.nfs4_acl',
thus calling lisxattr() with size = 16 will trigger the bug.
Add check on nfs4_listxattr() to return ERANGE error when it is
called with size > 0 and the return value is greater than size.

"value": "AV:L - The vulnerability is triggered by a local `listxattr(2)`/`llistxattr(2)`/`flistxattr(2)` syscall on a file residing on an NFSv4 mount; no network peer can initiate it on its own. Although the overflow content is supplied by the NFS server over the wire, a local syscall is required to reach the code, so the attack vector is Local.\nAC:L - Triggering is fully deterministic \u2014 the attacker probes with `size = 0`, then calls `listxattr()` with a size exactly equal to the generic handler list (16 bytes for `\"system.nfs4_acl\\0\"`), with no race to win and no memory-layout condition outside their control. The required config (CONFIG_NFS_V4_2, CONFIG_NFS_V4_SECURITY_LABEL, CONFIG_HARDENED_USERCOPY) is enabled by default on mainstream distributions, as demonstrated by the reporter reproducing on a stock Fedora 40 kernel.\nPR:L - Any unprivileged local user with ordinary access to a file on an existing NFSv4.2 mount can call `listxattr()` and set the `user.*` xattrs that become the overflow payload; no capabilities are needed. NFS-mounted home directories on shared/multi-user hosts make this a standard unprivileged-user reach.\nUI:N - The attacker performs every step \u2014 setting the xattrs and issuing the sized `listxattr()` call \u2014 with no action by any other user. The pre-existing NFS mount is an environmental property of the deployment, not an interaction the attacker must induce.\nS:U - The over-read, the leaked data, and the heap overflow all occur within the kernel\u0027s own memory and are delivered to the attacker\u0027s own process. No VM, IOMMU, or other security-authority boundary is crossed.\nC:H - When hardened usercopy is not enforcing, `copy_to_user()` transfers up to XATTR_LIST_MAX (64 KB) of kernel heap memory past a 16-byte kmalloc object directly into the attacker\u0027s buffer, with the over-read length controlled by how many `user.*` xattrs the attacker attaches to the file. This is a large, attacker-sized disclosure of adjacent slab contents including potential pointers and other tasks\u0027 data.\nI:H - The `size_t` underflow hands `nfs4_listxattr_nfs4_user()` a past-the-end pointer with an effectively unbounded length, and `decode_listxattrs()` then memcpy()s `user.\u003cattacker-chosen-name\u003e\\0` records past the end of a kmalloc-16 object in a loop until EOF. This is a heap buffer overflow with attacker-controlled content, length, and destination slab, which is a strong primitive for adjacent-object corruption and control-flow hijacking.\nA:H - The reported and reproducible outcome is `usercopy_abort()` calling `BUG()` at mm/usercopy.c:102 \u2014 a kernel oops that is a full panic on systems with `panic_on_oops` (common on embedded, automotive, and hardened deployments), repeatable at will by any local user. The heap overflow path additionally corrupts slab metadata and adjacent objects, causing further crashes."

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: ncm: Avoid dropping datagrams of properly parsed NTBs
It is observed sometimes when tethering is used over NCM with Windows 11
as host, at some instances, the gadget_giveback has one byte appended at
the end of a proper NTB. When the NTB is parsed, unwrap call looks for
any leftover bytes in SKB provided by u_ether and if there are any pending
bytes, it treats them as a separate NTB and parses it. But in case the
second NTB (as per unwrap call) is faulty/corrupt, all the datagrams that
were parsed properly in the first NTB and saved in rx_list are dropped.
Adding a few custom traces showed the following:
[002] d..1 7828.532866: dwc3_gadget_giveback: ep1out:
req 000000003868811a length 1025/16384 zsI ==> 0
[002] d..1 7828.532867: ncm_unwrap_ntb: K: ncm_unwrap_ntb toprocess: 1025
[002] d..1 7828.532867: ncm_unwrap_ntb: K: ncm_unwrap_ntb nth: 1751999342
[002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb seq: 0xce67
[002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb blk_len: 0x400
[002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb ndp_len: 0x10
[002] d..1 7828.532869: ncm_unwrap_ntb: K: Parsed NTB with 1 frames
In this case, the giveback is of 1025 bytes and block length is 1024.
The rest 1 byte (which is 0x00) won't be parsed resulting in drop of
all datagrams in rx_list.
Same is case with packets of size 2048:
[002] d..1 7828.557948: dwc3_gadget_giveback: ep1out:
req 0000000011dfd96e length 2049/16384 zsI ==> 0
[002] d..1 7828.557949: ncm_unwrap_ntb: K: ncm_unwrap_ntb nth: 1751999342
[002] d..1 7828.557950: ncm_unwrap_ntb: K: ncm_unwrap_ntb blk_len: 0x800
Lecroy shows one byte coming in extra confirming that the byte is coming
in from PC:
Transfer 2959 - Bytes Transferred(1025) Timestamp((18.524 843 590)
- Transaction 8391 - Data(1025 bytes) Timestamp(18.524 843 590)
--- Packet 4063861
Data(1024 bytes)
Duration(2.117us) Idle(14.700ns) Timestamp(18.524 843 590)
--- Packet 4063863
Data(1 byte)
Duration(66.160ns) Time(282.000ns) Timestamp(18.524 845 722)
According to Windows driver, no ZLP is needed if wBlockLength is non-zero,
because the non-zero wBlockLength has already told the function side the
size of transfer to be expected. However, there are in-market NCM devices
that rely on ZLP as long as the wBlockLength is multiple of wMaxPacketSize.
To deal with such devices, it pads an extra 0 at end so the transfer is no
longer multiple of wMaxPacketSize.

When the NTB is parsed, unwrap call looks for\nany leftover bytes in SKB provided by u_ether and if there are any pending\nbytes, it treats them as a separate NTB and parses it. But in case the\nsecond NTB (as per unwrap call) is faulty/corrupt, all the datagrams that\nwere parsed properly in the first NTB and saved in rx_list are dropped.\n\nAdding a few custom traces showed the following:\n[002] d..1 7828.532866: dwc3_gadget_giveback: ep1out:\nreq 000000003868811a length 1025/16384 zsI ==\u003e 0\n[002] d..1 7828.532867: ncm_unwrap_ntb: K: ncm_unwrap_ntb toprocess: 1025\n[002] d..1 7828.532867: ncm_unwrap_ntb: K: ncm_unwrap_ntb nth: 1751999342\n[002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb seq: 0xce67\n[002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb blk_len: 0x400\n[002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb ndp_len: 0x10\n[002] d..1 7828.532869: ncm_unwrap_ntb: K: Parsed NTB with 1 frames\n\nIn this case, the giveback is of 1025 bytes and block length is 1024.\nThe rest 1 byte (which is 0x00) won\u0027t be parsed resulting in drop of\nall datagrams in rx_list.\n\nSame is case with packets of size 2048:\n[002] d..1 7828.557948: dwc3_gadget_giveback: ep1out:\nreq 0000000011dfd96e length 2049/16384 zsI ==\u003e 0\n[002] d..1 7828.557949: ncm_unwrap_ntb: K: ncm_unwrap_ntb nth: 1751999342\n[002] d..1 7828.557950: ncm_unwrap_ntb: K: ncm_unwrap_ntb blk_len: 0x800\n\nLecroy shows one byte coming in extra confirming that the byte is coming\nin from PC:\n\n Transfer 2959 - Bytes Transferred(1025) Timestamp((18.524 843 590)\n - Transaction 8391 - Data(1025 bytes) Timestamp(18.524 843 590)\n --- Packet 4063861\n Data(1024 bytes)\n Duration(2.117us) Idle(14.700ns) Timestamp(18.524 843 590)\n --- Packet 4063863\n Data(1 byte)\n Duration(66.160ns) Time(282.000ns) Timestamp(18.524 845 722)\n\nAccording to Windows driver, no ZLP is needed if wBlockLength is non-zero,\nbecause the non-zero wBlockLength has already told the function side the\nsize of transfer to be expected. However, there are in-market NCM devices\nthat rely on ZLP as long as the wBlockLength is multiple of wMaxPacketSize.\nTo deal with such devices, it pads an extra 0 at end so the transfer is no\nlonger multiple of wMaxPacketSize."

Summary
In the Linux kernel, the following vulnerability has been resolved:
mptcp: fix double-free on socket dismantle
when MPTCP server accepts an incoming connection, it clones its listener
socket. However, the pointer to 'inet_opt' for the new socket has the same
value as the original one: as a consequence, on program exit it's possible
to observe the following splat:

"value": "AV:N - The vulnerable clone occurs in `subflow_syn_recv_sock()` during softirq processing of a received MPTCP third-ACK (ip_rcv \u2192 tcp_v4_rcv \u2192 tcp_check_req), so any remote host able to reach the MPTCP listening port triggers it. Both the aliasing and the subsequent frees are driven entirely by attacker-sent packets.\nAC:L - On an MPTCP server with NetLabel/CIPSO labeling (the shipped SELinux-MLS/Smack configuration in which this was reported), every completed MP_CAPABLE handshake deterministically clones the shared pointer, and each connection teardown frees it again \u2014 no race, no memory-layout dependency, and the attacker can repeat the connect/close cycle arbitrarily to control allocation interleaving.\nPR:N - The clone happens in the kernel\u0027s SYN-recv path before `accept()` and before any application-level authentication, so the attacker needs no credentials on the target at all. The listening socket is set up by the victim service, not by the attacker.\nUI:N - No victim action is needed beyond the MPTCP service already listening; the attacker completes the handshake and closes connections on its own.\nS:U - The corruption is confined to the kernel\u0027s own slab allocator within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The double free (and the IPv6 `ipv6_txoptions` refcount underflow) causes two live kernel objects to alias the same kmalloc-64 region, a well-known route to type confusion and arbitrary kernel-memory disclosure. Per kernel scoring guidance, use-after-free/double-free is scored High.\nI:H - Repeated frees of a still-referenced object corrupt the SLUB freelist, giving heap-spray and arbitrary-write primitives that can be leveraged for control-flow hijack and privilege escalation. The attacker can invoke the free primitive an unbounded number of times remotely.\nA:H - Even unweaponized, the double free produces slab corruption, a KASAN `kasan_report_invalid_free` BUG, or a kernel panic (the reported splat occurs in an RCU softirq callback), crashing the machine."

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: go7007: fix a memleak in go7007_load_encoder
In go7007_load_encoder, bounce(i.e. go->boot_fw), is allocated without
a deallocation thereafter. After the following call chain:
saa7134_go7007_init
|-> go7007_boot_encoder
|-> go7007_load_encoder
|-> kfree(go)
go is freed and thus bounce is leaked.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: Fix NULL domain on device release
In the kdump kernel, the IOMMU operates in deferred_attach mode. In this
mode, info->domain may not yet be assigned by the time the release_device
function is called. It leads to the following crash in the crash kernel:
BUG: kernel NULL pointer dereference, address: 000000000000003c
...
RIP: 0010:do_raw_spin_lock+0xa/0xa0
...

Use the release_domain mechanism to fix it. The scalable mode context
entry which is not part of release domain should be cleared in
release_device().

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs,hugetlb: fix NULL pointer dereference in hugetlbs_fill_super
When configuring a hugetlb filesystem via the fsconfig() syscall, there is
a possible NULL dereference in hugetlbfs_fill_super() caused by assigning
NULL to ctx->hstate in hugetlbfs_parse_param() when the requested pagesize
is non valid.
E.g: Taking the following steps:
fd = fsopen("hugetlbfs", FSOPEN_CLOEXEC);
fsconfig(fd, FSCONFIG_SET_STRING, "pagesize", "1024", 0);
fsconfig(fd, FSCONFIG_CMD_CREATE, NULL, NULL, 0);
Given that the requested "pagesize" is invalid, ctxt->hstate will be replaced
with NULL, losing its previous value, and we will print an error:
...
...
case Opt_pagesize:
ps = memparse(param->string, &rest);
ctx->hstate = h;
if (!ctx->hstate) {
pr_err("Unsupported page size %lu MB\n", ps / SZ_1M);
return -EINVAL;
}
return 0;
...
...
This is a problem because later on, we will dereference ctxt->hstate in
hugetlbfs_fill_super()
...
...
sb->s_blocksize = huge_page_size(ctx->hstate);
...
...
Causing below Oops.
Fix this by replacing cxt->hstate value only when then pagesize is known
to be valid.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/aio: Restrict kiocb_set_cancel_fn() to I/O submitted via libaio
If kiocb_set_cancel_fn() is called for I/O submitted via io_uring, the
following kernel warning appears:
WARNING: CPU: 3 PID: 368 at fs/aio.c:598 kiocb_set_cancel_fn+0x9c/0xa8
Call trace:
kiocb_set_cancel_fn+0x9c/0xa8

Fix this by setting the IOCB_AIO_RW flag for read and write I/O that is
submitted by libaio.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: misc: ljca: Fix double free in error handling path
When auxiliary_device_add() returns error and then calls
auxiliary_device_uninit(), callback function ljca_auxdev_release
calls kfree(auxdev->dev.platform_data) to free the parameter data
of the function ljca_new_client_device. The callers of
ljca_new_client_device shouldn't call kfree() again
in the error handling path to free the platform data.
Fix this by cleaning up the redundant kfree() in all callers and
adding kfree() the passed in platform_data on errors which happen
before auxiliary_device_init() succeeds .

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: rfcomm: Fix null-ptr-deref in rfcomm_check_security
During our fuzz testing of the connection and disconnection process at the
RFCOMM layer, we discovered this bug. By comparing the packets from a
normal connection and disconnection process with the testcase that
triggered a KASAN report. We analyzed the cause of this bug as follows:
1. In the packets captured during a normal connection, the host sends a
`Read Encryption Key Size` type of `HCI_CMD` packet
(Command Opcode: 0x1408) to the controller to inquire the length of
encryption key.After receiving this packet, the controller immediately
replies with a Command Completepacket (Event Code: 0x0e) to return the
Encryption Key Size.
2. In our fuzz test case, the timing of the controller's response to this
packet was delayed to an unexpected point: after the RFCOMM and L2CAP
layers had disconnected but before the HCI layer had disconnected.
3. After receiving the Encryption Key Size Response at the time described
in point 2, the host still called the rfcomm_check_security function.
However, by this time `struct l2cap_conn *conn = l2cap_pi(sk)->chan->conn;`
had already been released, and when the function executed
`return hci_conn_security(conn->hcon, d->sec_level, auth_type, d->out);`,
specifically when accessing `conn->hcon`, a null-ptr-deref error occurred.
To fix this bug, check if `sk->sk_state` is BT_CLOSED before calling
rfcomm_recv_frame in rfcomm_process_rx.

By comparing the packets from a\nnormal connection and disconnection process with the testcase that\ntriggered a KASAN report. We analyzed the cause of this bug as follows:\n\n1. In the packets captured during a normal connection, the host sends a\n`Read Encryption Key Size` type of `HCI_CMD` packet\n(Command Opcode: 0x1408) to the controller to inquire the length of\nencryption key.After receiving this packet, the controller immediately\nreplies with a Command Completepacket (Event Code: 0x0e) to return the\nEncryption Key Size.\n\n2. In our fuzz test case, the timing of the controller\u0027s response to this\npacket was delayed to an unexpected point: after the RFCOMM and L2CAP\nlayers had disconnected but before the HCI layer had disconnected.\n\n3. After receiving the Encryption Key Size Response at the time described\nin point 2, the host still called the rfcomm_check_security function.\nHowever, by this time `struct l2cap_conn *conn = l2cap_pi(sk)-\u003echan-\u003econn;`\nhad already been released, and when the function executed\n`return hci_conn_security(conn-\u003ehcon, d-\u003esec_level, auth_type, d-\u003eout);`,\nspecifically when accessing `conn-\u003ehcon`, a null-ptr-deref error occurred.\n\nTo fix this bug, check if `sk-\u003esk_state` is BT_CLOSED before calling\nrfcomm_recv_frame in rfcomm_process_rx."

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: core: Fix deadlock in usb_deauthorize_interface()
Among the attribute file callback routines in
drivers/usb/core/sysfs.c, the interface_authorized_store() function is
the only one which acquires a device lock on an ancestor device: It
calls usb_deauthorize_interface(), which locks the interface's parent
USB device.
The will lead to deadlock if another process already owns that lock
and tries to remove the interface, whether through a configuration
change or because the device has been disconnected. As part of the
removal procedure, device_del() waits for all ongoing sysfs attribute
callbacks to complete. But usb_deauthorize_interface() can't complete
until the device lock has been released, and the lock won't be
released until the removal has finished.
The mechanism provided by sysfs to prevent this kind of deadlock is
to use the sysfs_break_active_protection() function, which tells sysfs
not to wait for the attribute callback.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: delay all of ath9k_wmi_event_tasklet() until init is complete
The ath9k_wmi_event_tasklet() used in ath9k_htc assumes that all the data
structures have been fully initialised by the time it runs. However, because of
the order in which things are initialised, this is not guaranteed to be the
case, because the device is exposed to the USB subsystem before the ath9k driver
initialisation is completed.
We already committed a partial fix for this in commit:
8b3046abc99e ("ath9k_htc: fix NULL pointer dereference at ath9k_htc_tx_get_packet()")
However, that commit only aborted the WMI_TXSTATUS_EVENTID command in the event
tasklet, pairing it with an "initialisation complete" bit in the TX struct. It
seems syzbot managed to trigger the race for one of the other commands as well,
so let's just move the existing synchronisation bit to cover the whole
tasklet (setting it at the end of ath9k_htc_probe_device() instead of inside
ath9k_tx_init()).

In the Linux kernel, the following vulnerability has been resolved:
mmc: core: Avoid negative index with array access
Commit 4d0c8d0aef63 ("mmc: core: Use mrq.sbc in close-ended ffu") assigns
prev_idata = idatas[i - 1], but doesn't check that the iterator i is
greater than zero. Let's fix this by adding a check.

There is no remote or adjacent-network path into drivers/mmc/core/block.c.\nAC:L - Triggering requires the uninitialized `flags` field (kmalloc\u0027d throughout the affected range) to have MMC_BLK_IOC_SBC set on the first command, which the attacker controls by grooming the kmalloc-96/128 slab before the ioctl, and which can be retried in a tight loop at no cost. The subsequent `idatas[-1]` neighbor (an adjacent kmalloc-8 object or a live stack slot) is likewise attacker-influenceable via standard heap/stack spraying.\nPR:L - The RPMB character-device entry point (mmc_rpmb_ioctl \u2192 mmc_blk_ioctl_cmd/mmc_blk_ioctl_multi_cmd) performs no capable() check whatsoever \u2014 only DAC permissions on /dev/mmcblkNrpmb gate it \u2014 and on Android and embedded platforms that node is routinely opened by non-root system daemons, so an unprivileged-but-authorized local process suffices.\nUI:N - The attacker issues the ioctl directly from their own process; no victim action, mount, or file open by another user is needed.\nS:U - The out-of-bounds access and the resulting corruption are entirely within the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The negative index performs an out-of-bounds read of a pointer, and the resulting `prev_idata-\u003eic.arg` dereference reads attacker-chosen kernel memory that is then emitted as the CMD23 argument; more broadly the memory corruption is leverageable for kernel information disclosure.\nI:H - `memcpy(\u0026prev_idata-\u003eic.response, sbc.resp, sizeof(sbc.resp))` performs a 16-byte write through the out-of-bounds-derived pointer, giving a write primitive at a heap-groomable address (or over live kernel pointers on the stack) that is exploitable for privilege escalation.\nA:H - Dereferencing the wild `idatas[-1]` pointer \u2014 read at `prev_idata-\u003eic.arg` and write at `prev_idata-\u003eic.response` \u2014 reliably produces a kernel oops/panic in the common case where the neighboring memory is not a valid object."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: Add some bounds checking to firmware data
Smatch complains about "head->full_size - head->header_size" can
underflow. To some extent, we're always going to have to trust the
firmware a bit. However, it's easy enough to add a check for negatives,
and let's add a upper bounds check as well.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm: call the resume method on internal suspend
There is this reported crash when experimenting with the lvm2 testsuite.
The list corruption is caused by the fact that the postsuspend and resume
methods were not paired correctly; there were two consecutive calls to the
origin_postsuspend function. The second call attempts to remove the
"hash_list" entry from a list, while it was already removed by the first
call.
Fix __dm_internal_resume so that it calls the preresume and resume
methods of the table's targets.
If a preresume method of some target fails, we are in a tricky situation.
We can't return an error because dm_internal_resume isn't supposed to
return errors. We can't return success, because then the "resume" and
"postsuspend" methods would not be paired correctly. So, we set the
DMF_SUSPENDED flag and we fake normal suspend - it may confuse userspace
tools, but it won't cause a kernel crash.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndm: call the resume method on internal suspend\n\nThere is this reported crash when experimenting with the lvm2 testsuite.\nThe list corruption is caused by the fact that the postsuspend and resume\nmethods were not paired correctly; there were two consecutive calls to the\norigin_postsuspend function. The second call attempts to remove the\n\"hash_list\" entry from a list, while it was already removed by the first\ncall.\n\nFix __dm_internal_resume so that it calls the preresume and resume\nmethods of the table\u0027s targets.\n\nIf a preresume method of some target fails, we are in a tricky situation.\nWe can\u0027t return an error because dm_internal_resume isn\u0027t supposed to\nreturn errors. We can\u0027t return success, because then the \"resume\" and\n\"postsuspend\" methods would not be paired correctly. So, we set the\nDMF_SUSPENDED flag and we fake normal suspend - it may confuse userspace\ntools, but it won\u0027t cause a kernel crash.\n\n------------[ cut here ]------------\nkernel BUG at lib/list_debug.c:56!\ninvalid opcode: 0000 [#1] PREEMPT SMP\nCPU: 1 PID: 8343 Comm: dmsetup Not tainted 6.8.0-rc6 #4\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-2 04/01/2014\nRIP: 0010:__list_del_entry_valid_or_report+0x77/0xc0\n\u003csnip\u003e\nRSP: 0018:ffff8881b831bcc0 EFLAGS: 00010282\nRAX: 000000000000004e RBX: ffff888143b6eb80 RCX: 0000000000000000\nRDX: 0000000000000001 RSI: ffffffff819053d0 RDI: 00000000ffffffff\nRBP: ffff8881b83a3400 R08: 00000000fffeffff R09: 0000000000000058\nR10: 0000000000000000 R11: ffffffff81a24080 R12: 0000000000000001\nR13: ffff88814538e000 R14: ffff888143bc6dc0 R15: ffffffffa02e4bb0\nFS: 00000000f7c0f780(0000) GS:ffff8893f0a40000(0000) knlGS:0000000000000000\nCS: 0010 DS: 002b ES: 002b CR0: 0000000080050033\nCR2: 0000000057fb5000 CR3: 0000000143474000 CR4: 00000000000006b0\nCall Trace:\n \u003cTASK\u003e\n ? die+0x2d/0x80\n ? do_trap+0xeb/0xf0\n ? __list_del_entry_valid_or_report+0x77/0xc0\n ? do_error_trap+0x60/0x80\n ? __list_del_entry_valid_or_report+0x77/0xc0\n ? exc_invalid_op+0x49/0x60\n ? __list_del_entry_valid_or_report+0x77/0xc0\n ? asm_exc_invalid_op+0x16/0x20\n ? table_deps+0x1b0/0x1b0 [dm_mod]\n ? __list_del_entry_valid_or_report+0x77/0xc0\n origin_postsuspend+0x1a/0x50 [dm_snapshot]\n dm_table_postsuspend_targets+0x34/0x50 [dm_mod]\n dm_suspend+0xd8/0xf0 [dm_mod]\n dev_suspend+0x1f2/0x2f0 [dm_mod]\n ? table_deps+0x1b0/0x1b0 [dm_mod]\n ctl_ioctl+0x300/0x5f0 [dm_mod]\n dm_compat_ctl_ioctl+0x7/0x10 [dm_mod]\n __x64_compat_sys_ioctl+0x104/0x170\n do_syscall_64+0x184/0x1b0\n entry_SYSCALL_64_after_hwframe+0x46/0x4e\nRIP: 0033:0xf7e6aead\n\u003csnip\u003e\n---[ end trace 0000000000000000 ]---"

"value": "AV:L - The vulnerability is reached only through the device-mapper control device `/dev/mapper/control` via `DM_DEV_SUSPEND`/`DM_DEV_RESUME` ioctls (`ctl_ioctl` \u2192 `dev_suspend` \u2192 `pool_presuspend`/`pool_resume` \u2192 `dm_internal_suspend_noflush`/`dm_internal_resume`). There is no network or remote-peer input involved.\nAC:L - The attacker fully controls the entire trigger sequence with plain dmsetup ioctls \u2014 create a thin pool and a thin device whose table also carries a snapshot-origin (or cache/raid) segment, suspend and resume the pool, then suspend or remove the thin device. No race must be won and no unpredictable memory layout is required; the double `list_del()` / unbalanced `down_write()` is deterministic.\nPR:L - The dm ioctl path is administrative, but in the deployments where this matters (container runtimes using the devicemapper/thin storage driver, CSI storage plugins, privileged containers granted CAP_SYS_ADMIN, and appliances where LVM operations are delegated), the actor triggering it is a low-privileged tenant relative to the host kernel, consistent with how other device-mapper flaws in this subsystem are rated.\nUI:N - The attacker performs every step itself \u2014 table load, pool suspend/resume, device suspend/remove \u2014 through its own ioctl calls. No action by any other user or administrator is needed.\nS:U - The corruption and the resulting crash/hang are confined to the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The unbalanced postsuspend/resume corrupts kernel state \u2014 a global linked list (`_dm_origins`) is operated on with stale/poisoned entries, and targets keep serving I/O with desynchronized mapping metadata (dm-cache migration state, dm-integrity journal/commit sequence, dm-snapshot origin registration), which is memory/state corruption that can be steered toward exposing kernel or foreign-volume data.\nI:H - This is a kernel list-corruption bug (double `list_del()` on `dm_origin-\u003ehash_list`), and the missing `.resume`/`.preresume` calls leave targets running with committed-but-not-reinitialized on-disk state \u2014 dm-integrity\u0027s journal is re-initialized and its autocommit timer deleted while writes continue, and dm-cache/dm-raid mapping state is left stale, permitting silent corruption of data stored on the mapped device.\nA:H - The reported failure is `kernel BUG at lib/list_debug.c:56` (invalid opcode oops) in `origin_postsuspend` reached from `dm_suspend`, taken while `_origins_lock` is write-held, so the box either panics or permanently wedges all further dm/snapshot operations. Equivalent unbalanced paths in dm-cache (`prevent_background_work` \u2192 unmatched `down_write`) and dm-raid1 (`dm_rh_stop_recovery`) produce unkillable hangs holding `md-\u003esuspend_lock`."

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_set_pipapo: release elements in clone only from destroy path
Clone already always provides a current view of the lookup table, use it
to destroy the set, otherwise it is possible to destroy elements twice.
This fix requires:
212ed75dc5fb ("netfilter: nf_tables: integrate pipapo into commit protocol")
which came after:
9827a0e6e23b ("netfilter: nft_set_pipapo: release elements in clone from abort path").

empty element. Add such entry to the end of the arrays where it
is missing in order to avoid possible out-of-bound access when
the table is traversed by functions like qcom_find_freq() or
qcom_find_freq_floor().
Only compile tested.

"value": "AV:L - The vulnerable frequency-table walk lives in an on-SoC global clock-controller driver reached only through in-kernel `clk_set_rate()`/`clk_round_rate()` requests originating from local device access (the PCIe/QMP-PHY aux clock consumers and the sdhci-msm/ICE storage path). No network protocol, packet, or remote peer data reaches `qcom_find_freq()`.\nAC:L - The overrun is fully deterministic \u2014 any rate request exceeding the table\u0027s top entry (19.2 MHz for PCIe aux, 308.57 MHz for SDCC ICE core) runs `for (; f-\u003efreq; f++)` off the array end every time, with no race to win and no memory-layout grooming needed to leave the array. Only the exact bytes read afterwards depend on link layout, not the ability to trigger the defect.\nPR:L - No real-root or init-namespace capability check guards the rate-setting path; the affected RCGs are re-programmed by consumer drivers on paths a basic local user can provoke (device-node open triggering runtime-PM resume on the PCIe controller, eMMC/SD I/O through the ICE-backed storage path). Basic local privileges suffice rather than genuine root.\nUI:N - The out-of-bounds traversal happens entirely inside the kernel clock framework when a rate is requested during normal driver operation. No victim must mount a filesystem, open a file, or take any other action.\nS:U - The out-of-bounds read, the mis-programmed RCG registers, and any resulting fault all remain within the kernel\u0027s own security authority on the affected SoC. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - `qcom_find_freq()` reads an unbounded distance past the end of the array through adjacent kernel `.rodata` until it happens to hit a zero `freq` word, so the disclosure is not bounded to a few bytes. The out-of-bounds word is propagated back to the caller as `req-\u003erate = f-\u003efreq` in `_freq_tbl_determine_rate()` and into readable clock state, potentially exposing relocated pointer values usable to defeat KASLR.\nI:L - There is no out-of-bounds write and no kernel memory corruption \u2014 `src` is validated by `qcom_find_src_index()` and `m`/`n`/`pre_div` are mask-limited before reaching hardware \u2014 but out-of-bounds-derived values are still programmed into the SoC\u0027s RCG control registers via `clk_rcg2_configure()`, mis-configuring the PCIe aux or SDCC inline-crypto-engine clock and risking corrupt transfers on the eMMC/SD path.\nA:H - With `IPQ_GCC_8074` built as a module the tables sit in vmalloc\u0027d module `.rodata`, so the unbounded walk can hit an unmapped guard region and oops the kernel. Short of that, an out-of-spec divider/source programmed onto a live PCIe aux or storage ICE clock makes `update_config()` time out into `WARN(1)` \u2014 a panic under `panic_on_warn` \u2014 and can wedge the affected peripheral."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: Fix a null pointer crash in mtk_drm_crtc_finish_page_flip
It's possible that mtk_crtc->event is NULL in
mtk_drm_crtc_finish_page_flip().
pending_needs_vblank value is set by mtk_crtc->event, but in
mtk_drm_crtc_atomic_flush(), it's is not guarded by the same
lock in mtk_drm_finish_page_flip(), thus a race condition happens.
Consider the following case:
CPU1 CPU2
step 1:
mtk_drm_crtc_atomic_begin()
mtk_crtc->event is not null,
step 1:
mtk_drm_crtc_atomic_flush:
mtk_drm_crtc_update_config(
!!mtk_crtc->event)
step 2:
mtk_crtc_ddp_irq ->
mtk_drm_finish_page_flip:
lock
mtk_crtc->event set to null,
pending_needs_vblank set to false
unlock
pending_needs_vblank set to true,
step 2:
mtk_crtc_ddp_irq ->
mtk_drm_finish_page_flip called again,
pending_needs_vblank is still true
//null pointer
Instead of guarding the entire mtk_drm_crtc_atomic_flush(), it's more
efficient to just check if mtk_crtc->event is null before use.

Summary
In the Linux kernel, the following vulnerability has been resolved:
geneve: make sure to pull inner header in geneve_rx()
syzbot triggered a bug in geneve_rx() [1]
Issue is similar to the one I fixed in commit 8d975c15c0cd
("ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()")
We have to save skb->network_header in a temporary variable
in order to be able to recompute the network_header pointer
after a pskb_inet_may_pull() call.
pskb_inet_may_pull() makes sure the needed headers are in skb->head.

"value": "AV:N - The vulnerable code is the GENEVE UDP encapsulation receive handler for a socket bound to INADDR_ANY on UDP port 6081, reached directly from `udp_rcv()` on a received packet. In collect_md/external mode (standard OVS/OVN cloud overlay) `geneve_lookup_skb()` accepts any remote source address, so any host that can send UDP to the tunnel endpoint reaches `geneve_rx()`.\nAC:L - The attacker fully controls the skb layout: sending the encapsulated packet as IP fragments makes `ip_defrag()` produce a frag_list skb whose linear area ends exactly at the inner Ethernet header, deterministically placing `skb-\u003edata` at `skb-\u003etail` before the ECN read. Outer IP options and geneve option length give additional 4-byte tuning for NIC-driven fragment layouts.\nPR:N - There is no authentication, capability check, or credential validation anywhere on the `ip_rcv` \u2192 `udp_rcv` \u2192 `geneve_udp_encap_recv` \u2192 `geneve_rx` path. An unauthenticated remote peer only needs to send a crafted UDP datagram to the tunnel port.\nUI:N - The bug triggers entirely during softirq packet receive processing on the target host; no local user has to open, mount, or interact with anything.\nS:U - The uninitialized read occurs in kernel network receive context and its effects (ECN decision, packet drop) stay within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:L - The bug reads uninitialized kernel heap memory past the end of the valid skb data, but is strictly bounded to 1 byte (IPv4 TOS) or 2 bytes (IPv6 dsfield) and stays inside the `skb-\u003ehead` allocation. The stale contents are not returned to the attacker directly \u2014 they leak only as a per-packet drop/no-drop oracle from `__INET_ECN_decapsulate()`.\nI:L - The uninitialized byte drives whether the decapsulated packet is dropped and whether CE/ECT(1) marking is applied to tunneled traffic, so data traversing the tunnel can be modified or discarded based on garbage. The amount is minimal and the attacker has no control over the consequence; `INET_ECN_set_ce()`/`set_ect1()` are bounds-checked, so no out-of-bounds write primitive exists.\nA:L - Incorrect ECN decapsulation driven by uninitialized memory causes spurious drops of legitimate GENEVE-tunneled traffic (`err \u003e 1` \u2192 `kfree_skb`), degrading overlay connectivity. There is no kernel crash on production configurations \u2014 the read stays within the `skb-\u003ehead` slab object so KASAN does not fire, and only the KMSAN debug tool reports it."

net: ip_tunnel: prevent perpetual headroom growth

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/sched: fix null-ptr-deref in init entity
The bug can be triggered by sending an amdgpu_cs_wait_ioctl
to the AMDGPU DRM driver on any ASICs with valid context.
The bug was reported by Joonkyo Jung <joonkyoj@yonsei.ac.kr>.
For example the following code:
static void Syzkaller2(int fd)
{
union drm_amdgpu_ctx arg1;
union drm_amdgpu_wait_cs arg2;
arg1.in.op = AMDGPU_CTX_OP_ALLOC_CTX;
ret = drmIoctl(fd, 0x140106442 /* amdgpu_ctx_ioctl */, &arg1);
arg2.in.handle = 0x0;
arg2.in.timeout = 0x2000000000000;
arg2.in.ip_type = AMD_IP_VPE /* 0x9 */;
arg2->in.ip_instance = 0x0;
arg2.in.ring = 0x0;
arg2.in.ctx_id = arg1.out.alloc.ctx_id;
drmIoctl(fd, 0xc0206449 /* AMDGPU_WAIT_CS * /, &arg2);
}
The ioctl AMDGPU_WAIT_CS without previously submitted job could be assumed that
the error should be returned, but the following commit 1decbf6bb0b4dc56c9da6c5e57b994ebfc2be3aa
modified the logic and allowed to have sched_rq equal to NULL.
As a result when there is no job the ioctl AMDGPU_WAIT_CS returns success.
The change fixes null-ptr-deref in init entity and the stack below demonstrates
the error condition:

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: Fix writeback data corruption
cifs writeback doesn't correctly handle the case where
cifs_extend_writeback() hits a point where it is considering an additional
folio, but this would overrun the wsize - at which point it drops out of
the xarray scanning loop and calls xas_pause(). The problem is that
xas_pause() advances the loop counter - thereby skipping that page.
What needs to happen is for xas_reset() to be called any time we decide we
don't want to process the page we're looking at, but rather send the
request we are building and start a new one.
Fix this by copying and adapting the netfslib writepages code as a
temporary measure, with cifs writeback intending to be offloaded to
netfslib in the near future.
This also fixes the issue with the use of filemap_get_folios_tag() causing
retry of a bunch of pages which the extender already dealt with.
This can be tested by creating, say, a 64K file somewhere not on cifs
(otherwise copy-offload may get underfoot), mounting a cifs share with a
wsize of 64000, copying the file to it and then comparing the original file
and the copy:
dd if=/dev/urandom of=/tmp/64K bs=64k count=1
mount //192.168.6.1/test /mnt -o user=...,pass=...,wsize=64000
cp /tmp/64K /mnt/64K
cmp /tmp/64K /mnt/64K
Without the fix, the cmp fails at position 64000 (or shortly thereafter).

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix corruption during on-line resize
We observed a corruption during on-line resize of a file system that is
larger than 16 TiB with 4k block size. With having more then 2^32 blocks
resize_inode is turned off by default by mke2fs. The issue can be
reproduced on a smaller file system for convenience by explicitly
turning off resize_inode. An on-line resize across an 8 GiB boundary (the
size of a meta block group in this setup) then leads to a corruption:
dev=/dev/<some_dev> # should be >= 16 GiB
mkdir -p /corruption
/sbin/mke2fs -t ext4 -b 4096 -O ^resize_inode $dev $((2 * 2**21 - 2**15))
mount -t ext4 $dev /corruption
dd if=/dev/zero bs=4096 of=/corruption/test count=$((2*2**21 - 4*2**15))
sha1sum /corruption/test
# 79d2658b39dcfd77274e435b0934028adafaab11 /corruption/test
/sbin/resize2fs $dev $((2*2**21))
# drop page cache to force reload the block from disk
echo 1 > /proc/sys/vm/drop_caches
sha1sum /corruption/test
# 3c2abc63cbf1a94c9e6977e0fbd72cd832c4d5c3 /corruption/test
2^21 = 2^15*2^6 equals 8 GiB whereof 2^15 is the number of blocks per
block group and 2^6 are the number of block groups that make a meta
block group.
The last checksum might be different depending on how the file is laid
out across the physical blocks. The actual corruption occurs at physical
block 63*2^15 = 2064384 which would be the location of the backup of the
meta block group's block descriptor. During the on-line resize the file
system will be converted to meta_bg starting at s_first_meta_bg which is
2 in the example - meaning all block groups after 16 GiB. However, in
ext4_flex_group_add we might add block groups that are not part of the
first meta block group yet. In the reproducer we achieved this by
substracting the size of a whole block group from the point where the
meta block group would start. This must be considered when updating the
backup block group descriptors to follow the non-meta_bg layout. The fix
is to add a test whether the group to add is already part of the meta
block group or not.

There is no network, adjacent-network, or physical path into `dp_dsc_clock_en_read()`.\nAC:H - The overflow can only occur if `dsc_state.dsc_clock_en` formats to 10 or more characters, but that value is extracted from the DSC_TOP_CONTROL.DSC_CLOCK_EN register whose mask is 0x00000001 on every ASIC generation, so it is always 0 or 1 \u2014 a bound the attacker cannot influence. Triggering the mis-sized `snprintf()` is trivial, but making it actually write out of bounds depends on hardware register state entirely outside attacker control.\nPR:L - The node is created with mode 0644 and requires no capability check in the read path, so any local account able to traverse debugfs can reach it \u2014 the norm on Android, ChromeOS, embedded graphics stacks and IGT/debug setups that grant a non-root graphics account access to /sys/kernel/debug/dri. This matches the PR:L already assigned to the analogous amdgpu debugfs read in CVE-2024-35795.\nUI:N - The attacker simply reads the file; no victim action, modeset, or privileged helper invocation is needed. The DisplayPort/eDP connector node exists automatically whenever the amdgpu display driver has bound to the GPU.\nS:U - The affected `rd_buf` allocation and any resulting slab corruption live entirely within the kernel\u0027s own security authority. No VM, hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - Under the potential-overflow framing, the mis-sized `snprintf()` bound permits a heap out-of-bounds write past a 10-byte kcalloc allocation, and per scoring guidance memory corruption of this kind is treated as leverageable for kernel information disclosure. The read-back loop itself is bounded by `rd_buf_size` and the buffer is zeroed by kcalloc, so there is no direct read primitive.\nI:H - An out-of-bounds heap write is scored as High integrity impact, since corruption of slab contents beyond the allocated 10 bytes is the classic primitive for control-flow hijacking. The written bytes are the ASCII rendering of a kernel-controlled value rather than attacker-chosen data, which limits practical exploitability.\nA:H - Writing past the end of the kmalloc\u0027d buffer corrupts allocator state adjacent to the object and trips redzone/KASAN out-of-bounds checks, either of which results in a kernel oops or panic. Any such heap corruption is scored as a full availability loss."

In the Linux kernel, the following vulnerability has been resolved:
io_uring/net: fix overflow check in io_recvmsg_mshot_prep()
The "controllen" variable is type size_t (unsigned long). Casting it
to int could lead to an integer underflow.
The check_add_overflow() function considers the type of the destination
which is type int. If we add two positive values and the result cannot
fit in an integer then that's counted as an overflow.
However, if we cast "controllen" to an int and it turns negative, then
negative values *can* fit into an int type so there is no overflow.
Good: 100 + (unsigned long)-4 = 96 <-- overflow
Bad: 100 + (int)-4 = 96 <-- no overflow
I deleted the cast of the sizeof() as well. That's not a bug but the
cast is unnecessary.

This is an attacker-controlled out-of-bounds write with an attacker-chosen offset and length.\nA:H - With msg_controllen set to a near-2^64 value and the header length invariant broken, the recvmsg path operates on corrupted size state and writes outside the validated buffer, producing faults and corrupted request accounting that can be triggered repeatedly by an unprivileged user. Scoring the higher option consistent with a memory-safety violation."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix stackmap overflow check on 32-bit arches
The stackmap code relies on roundup_pow_of_two() to compute the number
of hash buckets, and contains an overflow check by checking if the
resulting value is 0. However, on 32-bit arches, the roundup code itself
can overflow by doing a 32-bit left-shift of an unsigned long value,
which is undefined behaviour, so it is not guaranteed to truncate
neatly. This was triggered by syzbot on the DEVMAP_HASH type, which
contains the same check, copied from the hashtab code.
The commit in the fixes tag actually attempted to fix this, but the fix
did not account for the UB, so the fix only works on CPUs where an
overflow does result in a neat truncation to zero, which is not
guaranteed. Checking the value before rounding does not have this
problem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add 'replay' NULL check in 'edp_set_replay_allow_active()'
In the first if statement, we're checking if 'replay' is NULL. But in
the second if statement, we're not checking if 'replay' is NULL again
before calling replay->funcs->replay_set_power_opt().
if (replay == NULL && force_static)
return false;
...
if (link->replay_settings.replay_feature_enabled &&
replay->funcs->replay_set_power_opt) {
replay->funcs->replay_set_power_opt(replay, *power_opts, panel_inst);
link->replay_settings.replay_power_opt_active = *power_opts;
}
If 'replay' is NULL, this will cause a null pointer dereference.
Fixes the below found by smatch:
drivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/link_edp_panel_control.c:895 edp_set_replay_allow_active() error: we previously assumed 'replay' could be null (see line 887)

Summary
In the Linux kernel, the following vulnerability has been resolved:
soc: fsl: qbman: Use raw spinlock for cgr_lock
smp_call_function always runs its callback in hard IRQ context, even on
PREEMPT_RT, where spinlocks can sleep. So we need to use a raw spinlock
for cgr_lock to ensure we aren't waiting on a sleeping task.
Although this bug has existed for a while, it was not apparent until
commit ef2a8d5478b9 ("net: dpaa: Adjust queue depth on rate change")
which invokes smp_call_function_single via qman_update_cgr_safe every
time a link goes up or down.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix race in read_extent_buffer_pages()
There are reports from tree-checker that detects corrupted nodes,
without any obvious pattern so possibly an overwrite in memory.
After some debugging it turns out there's a race when reading an extent
buffer the uptodate status can be missed.
To prevent concurrent reads for the same extent buffer,
read_extent_buffer_pages() performs these checks:
/* (1) */
if (test_bit(EXTENT_BUFFER_UPTODATE, &eb->bflags))
return 0;
/* (2) */
if (test_and_set_bit(EXTENT_BUFFER_READING, &eb->bflags))
goto done;
At this point, it seems safe to start the actual read operation. Once
that completes, end_bbio_meta_read() does
/* (3) */
set_extent_buffer_uptodate(eb);
/* (4) */
clear_bit(EXTENT_BUFFER_READING, &eb->bflags);
Normally, this is enough to ensure only one read happens, and all other
callers wait for it to finish before returning. Unfortunately, there is
a racey interleaving:
Thread A | Thread B | Thread C
---------+----------+---------
(1) | |
| (1) |
(2) | |
(3) | |
(4) | |
| (2) |
| | (1)
When this happens, thread B kicks of an unnecessary read. Worse, thread
C will see UPTODATE set and return immediately, while the read from
thread B is still in progress. This race could result in tree-checker
errors like this as the extent buffer is concurrently modified:
BTRFS critical (device dm-0): corrupted node, root=256
block=8550954455682405139 owner mismatch, have 11858205567642294356
expect [256, 18446744073709551360]
Fix it by testing UPTODATE again after setting the READING bit, and if
it's been set, skip the unnecessary read.

No network protocol handler is involved, so this requires local system access.\nAC:L - The attacker controls every side of the race \u2014 multiple threads performing concurrent lookups of the same cold metadata block, with readahead supplying the WAIT_NONE submitter \u2014 and can retry indefinitely while adding memory and CPU pressure to widen the window. The race is known to trigger spontaneously in production without any attacker.\nPR:L - Any unprivileged local user with read access to a mounted btrfs filesystem can drive concurrent metadata reads of the same extent buffer; btrfs is the default root filesystem on several major distributions. No capability, ioctl, mount privilege, or namespace trick is needed.\nUI:N - The attacker triggers the race entirely with its own file I/O against an already-mounted filesystem. No victim action or cooperation is required.\nS:U - The corruption occurs within kernel memory and on-disk metadata managed by the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - Threads consume extent-buffer contents while DMA concurrently overwrites them, yielding torn header/item fields; garbage node blockptrs and nritems drive reads of arbitrary logical addresses, and the resulting heap out-of-bounds access on struct btrfs_path is leverageable for kernel memory disclosure.\nI:H - btrfs_search_slot() writes p-\u003enodes[level] and p-\u003eslots[level] with an unvalidated 8-bit level taken from the racing memory, giving an out-of-bounds write of a kernel pointer past a kmalloc\u0027d btrfs_path; separately, a leaf modified under an in-flight overwrite is checksummed and written back, causing persistent on-disk metadata corruption.\nA:H - The documented outcome is tree-checker \"corrupted node\" reports leading to -EUCLEAN and transaction abort with the filesystem forced read-only, and the out-of-bounds writes and garbage tree traversal readily produce ASSERT/BUG_ON hits and kernel oopses."

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvmet-fc: avoid deadlock on delete association path
When deleting an association the shutdown path is deadlocking because we
try to flush the nvmet_wq nested. Avoid this by deadlock by deferring
the put work into its own work item.

This matches the treatment of other NVMe target transports (nvmet-tcp/nvmet-fc) as network-reachable, and is consistent with CVE-2025-40171 on the same code.\nAC:L - A remote peer controls both sides of the race \u2014 it repeatedly creates associations and issues Disconnect Association LSes (or drops connectivity, triggering `nvmet_fc_invalidate_host()`), driving `del_work` and the LS completion onto `nvmet_wq` at will while the targetport reference count is winding down.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NTB: fix possible name leak in ntb_register_device()
If device_register() fails in ntb_register_device(), the device name
allocated by dev_set_name() should be freed. As per the comment in
device_register(), callers should use put_device() to give up the
reference in the error path. So fix this by calling put_device() in the
error path so that the name can be freed in kobject_cleanup().
As a result of this, put_device() in the error path of
ntb_register_device() is removed and the actual error is returned.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: fsl-qdma: fix SoC may hang on 16 byte unaligned read
There is chip (ls1028a) errata:
The SoC may hang on 16 byte unaligned read transactions by QDMA.
Unaligned read transactions initiated by QDMA may stall in the NOC
(Network On-Chip), causing a deadlock condition. Stalled transactions will
trigger completion timeouts in PCIe controller.
Workaround:
Enable prefetch by setting the source descriptor prefetchable bit
( SD[PF] = 1 ).
Implement this workaround.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix hashtab overflow check on 32-bit arches
The hashtab code relies on roundup_pow_of_two() to compute the number of
hash buckets, and contains an overflow check by checking if the
resulting value is 0. However, on 32-bit arches, the roundup code itself
can overflow by doing a 32-bit left-shift of an unsigned long value,
which is undefined behaviour, so it is not guaranteed to truncate
neatly. This was triggered by syzbot on the DEVMAP_HASH type, which
contains the same check, copied from the hashtab code. So apply the same
fix to hashtab, by moving the overflow check to before the roundup.

However, on 32-bit arches, the roundup code itself\ncan overflow by doing a 32-bit left-shift of an unsigned long value,\nwhich is undefined behaviour, so it is not guaranteed to truncate\nneatly. This was triggered by syzbot on the DEVMAP_HASH type, which\ncontains the same check, copied from the hashtab code. So apply the same\nfix to hashtab, by moving the overflow check to before the roundup."

No network or physical access is involved.\nAC:L - Exploitation is fully deterministic: one map-create with max_entries \u003e 0x80000000 and one map-update, with no race, no timing window and no memory-layout condition outside the attacker\u0027s control. The 32-bit-arch requirement is a property of the target platform (ARM32/x86-32/MIPS32 dominate embedded, IoT, automotive and Android-era devices running these stable branches), not a condition the attacker must win.\nPR:L - BPF_MAP_TYPE_HASH/PERCPU_HASH/HASH_OF_MAPS sit in the explicitly \"unprivileged\" branch of map_create()\u0027s privilege switch, requiring no CAP_BPF; the only gate is sysctl_unprivileged_bpf_disabled, which defaults to 0 on the affected 4.19/5.4/5.10 branches and on any build without CONFIG_BPF_UNPRIV_DEFAULT_OFF. A plain local user account therefore suffices.\nUI:N - The attacker performs the entire sequence themselves via two syscalls; no victim action, mount, or file open is needed.\nS:U - The corruption and its effects are confined to kernel memory within the same security authority; no hypervisor, IOMMU or sandbox boundary is crossed.\nC:H - A bogus n_buckets that escapes the overflow check leaves htab-\u003ebuckets as a zero-sized ZERO_SIZE_PTR allocation while __select_bucket() indexes it with an unmasked, key-derived 32-bit offset, so lookups read and dereference attacker-chosen out-of-bounds kernel memory, yielding an arbitrary-read primitive.\nI:H - The same wild bucket pointer is written through by htab_lock_bucket() (raw_spinlock acquire) and hlist_nulls_add_head_rcu() during map update, giving an out-of-bounds write of kernel list pointers at an attacker-influenced offset \u2014 a corruption primitive suitable for control-flow hijack.\nA:H - The identical pattern was demonstrated by syzbot as a kernel crash on arm32, and even the benign UB outcome (n_buckets == 1 with a ~4-billion entry limit) forces unbounded hash-chain walks under a raw spinlock with IRQs disabled, producing hard lockups, RCU stalls and panics."

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix refcnt handling in __inet_hash_connect().
syzbot reported a warning in sk_nulls_del_node_init_rcu().
The commit 66b60b0c8c4a ("dccp/tcp: Unhash sk from ehash for tb2 alloc
failure after check_estalblished().") tried to fix an issue that an
unconnected socket occupies an ehash entry when bhash2 allocation fails.
In such a case, we need to revert changes done by check_established(),
which does not hold refcnt when inserting socket into ehash.
So, to revert the change, we need to __sk_nulls_add_node_rcu() instead
of sk_nulls_add_node_rcu().
Otherwise, sock_put() will cause refcnt underflow and leak the socket.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: Create debugfs ttm_resource_manager entry only if needed
The driver creates /sys/kernel/debug/dri/0/mob_ttm even when the
corresponding ttm_resource_manager is not allocated.
This leads to a crash when trying to read from this file.
Add a check to create mob_ttm, system_mob_ttm, and gmr_ttm debug file
only when the corresponding ttm_resource_manager is allocated.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tmpfs: fix race on handling dquot rbtree
A syzkaller reproducer found a race while attempting to remove dquot
information from the rb tree.
Fetching the rb_tree root node must also be protected by the
dqopt->dqio_sem, otherwise, giving the right timing, shmem_release_dquot()
will trigger a warning because it couldn't find a node in the tree, when
the real reason was the root node changing before the search starts:
Thread 1 Thread 2
- shmem_release_dquot() - shmem_{acquire,release}_dquot()
- fetch ROOT - Fetch ROOT
- acquire dqio_sem
- wait dqio_sem
- do something, triger a tree rebalance
- release dqio_sem
- acquire dqio_sem
- start searching for the node, but
from the wrong location, missing
the node, and triggering a warning.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wireguard: receive: annotate data-race around receiving_counter.counter
Syzkaller with KCSAN identified a data-race issue when accessing
keypair->receiving_counter.counter. Use READ_ONCE() and WRITE_ONCE()
annotations to mark the data race as intentional.
BUG: KCSAN: data-race in wg_packet_decrypt_worker / wg_packet_rx_poll

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ice: Fix potential NULL pointer dereference in ice_bridge_setlink()
The function ice_bridge_setlink() may encounter a NULL pointer dereference
if nlmsg_find_attr() returns NULL and br_spec is dereferenced subsequently
in nla_for_each_nested(). To address this issue, add a check to ensure that
br_spec is not NULL before proceeding with the nested attribute iteration.

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.

DMA API debug brings to light leaking dma-mappings as dma_map_sg and
dma_unmap_sg are not correctly balanced.
If an error occurs in mmci_cmd_irq function, only mmci_dma_error
function is called and as this API is not managed on stm32 variant,
dma_unmap_sg is never called in this error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/mm: Ensure input to pfn_to_kaddr() is treated as a 64-bit type
On 64-bit platforms, the pfn_to_kaddr() macro requires that the input
value is 64 bits in order to ensure that valid address bits don't get
lost when shifting that input by PAGE_SHIFT to calculate the physical
address to provide a virtual address for.
One such example is in pvalidate_pages() (used by SEV-SNP guests), where
the GFN in the struct used for page-state change requests is a 40-bit
bit-field, so attempts to pass this GFN field directly into
pfn_to_kaddr() ends up causing guest crashes when dealing with addresses
above the 1TB range due to the above.
Fix this issue with SEV-SNP guests, as well as any similar cases that
might cause issues in current/future code, by using an inline function,
instead of a macro, so that the input is implicitly cast to the
expected 64-bit input type prior to performing the shift operation.
While it might be argued that the issue is on the caller side, other
archs/macros have taken similar approaches to deal with instances like
this, such as ARM explicitly casting the input to phys_addr_t:
e48866647b48 ("ARM: 8396/1: use phys_addr_t in pfn_to_kaddr()")
A C inline function is even better though.
[ mingo: Refined the changelog some more & added __always_inline. ]

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: fix deadlock between bd_link_disk_holder and partition scan
'open_mutex' of gendisk is used to protect open/close block devices. But
in bd_link_disk_holder(), it is used to protect the creation of symlink
between holding disk and slave bdev, which introduces some issues.
When bd_link_disk_holder() is called, the driver is usually in the process
of initialization/modification and may suspend submitting io. At this
time, any io hold 'open_mutex', such as scanning partitions, can cause
deadlocks. For example, in raid:
T1 T2
bdev_open_by_dev
lock open_mutex [1]
...
efi_partition
...
md_submit_bio
md_ioctl mddev_syspend
-> suspend all io
md_add_new_disk
bind_rdev_to_array
bd_link_disk_holder
try lock open_mutex [2]
md_handle_request
-> wait mddev_resume
T1 scan partition, T2 add a new device to raid. T1 waits for T2 to resume
mddev, but T2 waits for open_mutex held by T1. Deadlock occurs.
Fix it by introducing a local mutex 'blk_holder_mutex' to replace
'open_mutex'.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fat: fix uninitialized field in nostale filehandles
When fat_encode_fh_nostale() encodes file handle without a parent it
stores only first 10 bytes of the file handle. However the length of the
file handle must be a multiple of 4 so the file handle is actually 12
bytes long and the last two bytes remain uninitialized. This is not
great at we potentially leak uninitialized information with the handle
to userspace. Properly initialize the full handle length.

Summary
In the Linux kernel, the following vulnerability has been resolved:
arp: Prevent overflow in arp_req_get().
syzkaller reported an overflown write in arp_req_get(). [0]
When ioctl(SIOCGARP) is issued, arp_req_get() looks up an neighbour
entry and copies neigh->ha to struct arpreq.arp_ha.sa_data.
The arp_ha here is struct sockaddr, not struct sockaddr_storage, so
the sa_data buffer is just 14 bytes.
In the splat below, 2 bytes are overflown to the next int field,
arp_flags. We initialise the field just after the memcpy(), so it's
not a problem.
However, when dev->addr_len is greater than 22 (e.g. MAX_ADDR_LEN),
arp_netmask is overwritten, which could be set as htonl(0xFFFFFFFFUL)
in arp_ioctl() before calling arp_req_get().
To avoid the overflow, let's limit the max length of memcpy().
Note that commit b5f0de6df6dc ("net: dev: Convert sa_data to flexible
array in struct sockaddr") just silenced syzkaller.
[0]:
memcpy: detected field-spanning write (size 16) of single field "r->arp_ha.sa_data" at net/ipv4/arp.c:1128 (size 14)

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix racing between bpf_timer_cancel_and_free and bpf_timer_cancel
The following race is possible between bpf_timer_cancel_and_free
and bpf_timer_cancel. It will lead a UAF on the timer->timer.
bpf_timer_cancel();
spin_lock();
t = timer->time;
spin_unlock();
bpf_timer_cancel_and_free();
spin_lock();
t = timer->timer;
timer->timer = NULL;
spin_unlock();
hrtimer_cancel(&t->timer);
kfree(t);
/* UAF on t */
hrtimer_cancel(&t->timer);
In bpf_timer_cancel_and_free, this patch frees the timer->timer
after a rcu grace period. This requires a rcu_head addition
to the "struct bpf_hrtimer". Another kfree(t) happens in bpf_timer_init,
this does not need a kfree_rcu because it is still under the
spin_lock and timer->timer has not been visible by others yet.
In bpf_timer_cancel, rcu_read_lock() is added because this helper
can be used in a non rcu critical section context (e.g. from
a sleepable bpf prog). Other timer->timer usages in helpers.c
have been audited, bpf_timer_cancel() is the only place where
timer->timer is used outside of the spin_lock.
Another solution considered is to mark a t->flag in bpf_timer_cancel
and clear it after hrtimer_cancel() is done. In bpf_timer_cancel_and_free,
it busy waits for the flag to be cleared before kfree(t). This patch
goes with a straight forward solution and frees timer->timer after
a rcu grace period.

"value": "AV:L - Both sides of the race are driven through local syscalls \u2014 `bpf(BPF_PROG_LOAD)`/`BPF_PROG_TEST_RUN` to run a program calling `bpf_timer_cancel()`, and `BPF_MAP_DELETE_ELEM`/`close()` to drive `bpf_timer_cancel_and_free()`. No remotely supplied data reaches `kernel/bpf/helpers.c`, and BPF is classified as a local attack vector under kernel scoring guidance.\nAC:L - The attacker owns both racers \u2014 one thread runs its own BPF program calling `bpf_timer_cancel()` while another deletes the map element or drops the map uref \u2014 and can widen the window arbitrarily by making its own timer callback long-running, since `hrtimer_cancel()` blocks in `hrtimer_cancel_wait_running()` while the other thread finishes and `kfree()`s `t`. Nothing depends on state outside the attacker\u0027s control and the sequence can be retried in a tight loop.\nPR:L - The `bpf_timer_*` helpers are gated on `bpf_capable()` (CAP_BPF/CAP_SYS_ADMIN), a reduced non-root capability routinely delegated to unprivileged service, tracing and container workloads that are not init-namespace root. This matches this CNA\u0027s established scoring for the sibling `bpf_timer` UAFs CVE-2024-41045 and CVE-2024-42239.\nUI:N - The attacker loads its own program, arms its own timer, and issues both the cancel and the map-delete from its own threads. No victim action, mount, or interaction with any other principal is required.\nS:U - The freed `struct bpf_hrtimer` and the corrupted per-CPU hrtimer state are entirely kernel-internal, so the impact stays within the kernel\u0027s own security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - `hrtimer_active()` reads `timer-\u003ebase` out of the freed object and dereferences it (`base-\u003eseq`, `base-\u003erunning`), so reclaiming the 96-byte `kmalloc-cg-96` slot with sprayed data (e.g. `msg_msg`) turns this into an attacker-directed kernel-memory read, with the helper\u0027s return value acting as an oracle. That yields arbitrary kernel data disclosure and KASLR defeat.\nI:H - After `hrtimer_active()` returns true, `lock_hrtimer_base()` takes a spinlock at an attacker-controlled address and `remove_hrtimer()`/`__remove_hrtimer()` writes `timer-\u003estate`, performs `timerqueue_del()` rb-tree unlinking and clears bits in `cpu_base-\u003eactive_bases` through the same forged pointer. This is a controlled kernel write primitive suitable for privilege escalation.\nA:H - Even without a successful spray, operating on freed memory corrupts the per-CPU hrtimer queue and produces a KASAN splat, oops, or panic, and a garbage `timer-\u003ebase` sends `hrtimer_cancel()` into an unterminating retry loop. The attacker can trigger this at will, repeatedly."

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_core: Fix possible buffer overflow
struct hci_dev_info has a fixed size name[8] field so in the event that
hdev->name is bigger than that strcpy would attempt to write past its
size, so this fixes this problem by switching to use strscpy.

Summary
In the Linux kernel, the following vulnerability has been resolved:
aoe: fix the potential use-after-free problem in aoecmd_cfg_pkts
This patch is against CVE-2023-6270. The description of cve is:
A flaw was found in the ATA over Ethernet (AoE) driver in the Linux
kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on
`struct net_device`, and a use-after-free can be triggered by racing
between the free on the struct and the access through the `skbtxq`
global queue. This could lead to a denial of service condition or
potential code execution.
In aoecmd_cfg_pkts(), it always calls dev_put(ifp) when skb initial
code is finished. But the net_device ifp will still be used in
later tx()->dev_queue_xmit() in kthread. Which means that the
dev_put(ifp) should NOT be called in the success path of skb
initial code in aoecmd_cfg_pkts(). Otherwise tx() may run into
use-after-free because the net_device is freed.
This patch removed the dev_put(ifp) in the success path in
aoecmd_cfg_pkts(), and added dev_put() after skb xmit in tx().

The description of cve is:\n\n A flaw was found in the ATA over Ethernet (AoE) driver in the Linux\n kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on\n `struct net_device`, and a use-after-free can be triggered by racing\n between the free on the struct and the access through the `skbtxq`\n global queue. This could lead to a denial of service condition or\n potential code execution.\n\nIn aoecmd_cfg_pkts(), it always calls dev_put(ifp) when skb initial\ncode is finished. But the net_device ifp will still be used in\nlater tx()-\u003edev_queue_xmit() in kthread. Which means that the\ndev_put(ifp) should NOT be called in the success path of skb\ninitial code in aoecmd_cfg_pkts(). Otherwise tx() may run into\nuse-after-free because the net_device is freed.\n\nThis patch removed the dev_put(ifp) in the success path in\naoecmd_cfg_pkts(), and added dev_put() after skb xmit in tx()."

Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: fix race between tx work scheduling and socket close
Similarly to previous commit, the submitting thread (recvmsg/sendmsg)
may exit as soon as the async crypto handler calls complete().
Reorder scheduling the work before calling complete().
This seems more logical in the first place, as it's
the inverse order of what the submitting thread will do.

No local access to the target is needed.\nAC:L - The attacker controls both sides of the race \u2014 one side issues the sendmsg that leaves an async encryption in flight, the other issues the close that blocks in tls_encrypt_async_wait() and then frees ctx \u2014 and can retry across thousands of concurrent connections at no cost. No memory layout or victim state outside the attacker\u0027s influence is required.\nPR:N - A kTLS-offloading HTTPS server accepts connections from arbitrary unauthenticated clients with no client certificate in the typical deployment; locally, setsockopt(TCP_ULP,\"tls\") plus TLS_TX requires no capability at all once the tls module is loaded. Neither path needs an account or privilege on the target.\nUI:N - The race fires during ordinary kTLS record encryption and socket teardown on an established connection. No action by any local user or administrator is required.\nS:U - The use-after-free on struct tls_sw_context_tx and the resulting timer/workqueue corruption all occur in kernel memory managed by the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - After kfree(ctx) the callback and the later timer expiry re-read freed, attacker-groomable memory \u2014 timer-\u003efunction, dwork-\u003ewq, and tx_work-\u003esk, the last of which is dereferenced as a struct sock * by tx_work_handler/tls_tx_records. Controlling that fake sock and the redirected call is leverageable into arbitrary kernel memory disclosure.\nI:H - The stale callback performs an atomic bit-set into the reallocated slab object at a fixed offset and writes dwork-\u003ewq, dwork-\u003ecpu and timer-\u003eexpires into freed memory, then links that freed object into the global timer wheel. That yields a controlled heap write plus a function pointer read from reclaimed memory, i.e. a control-flow hijack primitive.\nA:H - Arming a delayed_work inside a freed slab object after cancel_delayed_work_sync() reliably produces slab and timer-wheel corruption, and tx_work_handler running against an already-freed TLS context oopses on the stale sk. Any of these panics the kernel."

Summary
In the Linux kernel, the following vulnerability has been resolved:
nouveau/dmem: handle kcalloc() allocation failure
The kcalloc() in nouveau_dmem_evict_chunk() will return null if
the physical memory has run out. As a result, if we dereference
src_pfns, dst_pfns or dma_addrs, the null pointer dereference bugs
will happen.
Moreover, the GPU is going away. If the kcalloc() fails, we could not
evict all pages mapping a chunk. So this patch adds a __GFP_NOFAIL
flag in kcalloc().
Finally, as there is no need to have physically contiguous memory,
this patch switches kcalloc() to kvcalloc() in order to avoid
failing allocations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfp: flower: handle acti_netdevs allocation failure
The kmalloc_array() in nfp_fl_lag_do_work() will return null, if
the physical memory has run out. As a result, if we dereference
the acti_netdevs, the null pointer dereference bugs will happen.
This patch adds a check to judge whether allocation failure occurs.
If it happens, the delayed work will be rescheduled and try again.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: cachestat: fix two shmem bugs
When cachestat on shmem races with swapping and invalidation, there
are two possible bugs:
1) A swapin error can have resulted in a poisoned swap entry in the
shmem inode's xarray. Calling get_shadow_from_swap_cache() on it
will result in an out-of-bounds access to swapper_spaces[].
Validate the entry with non_swap_entry() before going further.
2) When we find a valid swap entry in the shmem's inode, the shadow
entry in the swapcache might not exist yet: swap IO is still in
progress and we're before __remove_mapping; swapin, invalidation,
or swapoff have removed the shadow from swapcache after we saw the
shmem swap entry.
This will send a NULL to workingset_test_recent(). The latter
purely operates on pointer bits, so it won't crash - node 0, memcg
ID 0, eviction timestamp 0, etc. are all valid inputs - but it's a
bogus test. In theory that could result in a false "recently
evicted" count.
Such a false positive wouldn't be the end of the world. But for
code clarity and (future) robustness, be explicit about this case.
Bail on get_shadow_from_swap_cache() returning NULL.

No elevated privileges or namespace tricks are needed.\nUI:N - The attacker triggers the flaw entirely from their own process with a single syscall on a file descriptor they already hold. No action by any other user or victim process is required.\nS:U - The out-of-bounds access, wild dereference and resulting oops are all confined to the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The read past the end of `swapper_spaces[]` yields an unvalidated non-pointer value that is dereferenced as a `struct address_space` and walked as an xarray, so the kernel reads memory at an address it never bounds-checked; the value derived from that walk feeds `workingset_test_recent()` whose outcome is reflected in the `nr_recently_evicted` field copied back to userspace, forming a kernel-memory disclosure oracle. This is an unbounded out-of-bounds read, not a read strictly limited to a few bytes.\nI:N - The faulty path only performs reads (`xa_load`), and the memcg reference taken in `workingset_test_recent()` is released on all paths, so no kernel memory is written or corrupted and no write or control-flow-hijack primitive is produced. The only integrity effect is an inaccurate statistics counter returned to the caller.\nA:H - The out-of-bounds `swapper_spaces[31]` value is almost always zero (or unmapped garbage), producing a NULL/wild pointer dereference and kernel oops inside an `rcu_read_lock()` critical section; the leaked RCU nesting on task death can escalate to RCU stalls and a system-wide hang, and `panic_on_oops` systems panic outright."

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFS: Fix nfs_netfs_issue_read() xarray locking for writeback interrupt
The loop inside nfs_netfs_issue_read() currently does not disable
interrupts while iterating through pages in the xarray to submit
for NFS read. This is not safe though since after taking xa_lock,
another page in the mapping could be processed for writeback inside
an interrupt, and deadlock can occur. The fix is simple and clean
if we use xa_for_each_range(), which handles the iteration with RCU
while reducing code complexity.
The problem is easily reproduced with the following test:
mount -o vers=3,fsc 127.0.0.1:/export /mnt/nfs
dd if=/dev/zero of=/mnt/nfs/file1.bin bs=4096 count=1
echo 3 > /proc/sys/vm/drop_caches
dd if=/mnt/nfs/file1.bin of=/dev/null
umount /mnt/nfs
On the console with a lockdep-enabled kernel a message similar to
the following will be seen:

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nNFS: Fix nfs_netfs_issue_read() xarray locking for writeback interrupt\n\nThe loop inside nfs_netfs_issue_read() currently does not disable\ninterrupts while iterating through pages in the xarray to submit\nfor NFS read. This is not safe though since after taking xa_lock,\nanother page in the mapping could be processed for writeback inside\nan interrupt, and deadlock can occur. The fix is simple and clean\nif we use xa_for_each_range(), which handles the iteration with RCU\nwhile reducing code complexity.\n\nThe problem is easily reproduced with the following test:\n mount -o vers=3,fsc 127.0.0.1:/export /mnt/nfs\n dd if=/dev/zero of=/mnt/nfs/file1.bin bs=4096 count=1\n echo 3 \u003e /proc/sys/vm/drop_caches\n dd if=/mnt/nfs/file1.bin of=/dev/null\n umount /mnt/nfs\n\nOn the console with a lockdep-enabled kernel a message similar to\nthe following will be seen:\n\n ================================\n WARNING: inconsistent lock state\n 6.7.0-lockdbg+ #10 Not tainted\n --------------------------------\n inconsistent {IN-SOFTIRQ-W} -\u003e {SOFTIRQ-ON-W} usage.\n test5/1708 [HC0[0]:SC0[0]:HE1:SE1] takes:\n ffff888127baa598 (\u0026xa-\u003exa_lock#4){+.?.}-{3:3}, at:\nnfs_netfs_issue_read+0x1b2/0x4b0 [nfs]\n {IN-SOFTIRQ-W} state was registered at:\n lock_acquire+0x144/0x380\n _raw_spin_lock_irqsave+0x4e/0xa0\n __folio_end_writeback+0x17e/0x5c0\n folio_end_writeback+0x93/0x1b0\n iomap_finish_ioend+0xeb/0x6a0\n blk_update_request+0x204/0x7f0\n blk_mq_end_request+0x30/0x1c0\n blk_complete_reqs+0x7e/0xa0\n __do_softirq+0x113/0x544\n __irq_exit_rcu+0xfe/0x120\n irq_exit_rcu+0xe/0x20\n sysvec_call_function_single+0x6f/0x90\n asm_sysvec_call_function_single+0x1a/0x20\n pv_native_safe_halt+0xf/0x20\n default_idle+0x9/0x20\n default_idle_call+0x67/0xa0\n do_idle+0x2b5/0x300\n cpu_startup_entry+0x34/0x40\n start_secondary+0x19d/0x1c0\n secondary_startup_64_no_verify+0x18f/0x19b\n irq event stamp: 176891\n hardirqs last enabled at (176891): [\u003cffffffffa67a0be4\u003e]\n_raw_spin_unlock_irqrestore+0x44/0x60\n hardirqs last disabled at (176890): [\u003cffffffffa67a0899\u003e]\n_raw_spin_lock_irqsave+0x79/0xa0\n softirqs last enabled at (176646): [\u003cffffffffa515d91e\u003e]\n__irq_exit_rcu+0xfe/0x120\n softirqs last disabled at (176633): [\u003cffffffffa515d91e\u003e]\n__irq_exit_rcu+0xfe/0x120\n\n other info that might help us debug this:\n Possible unsafe locking scenario:\n\n CPU0\n ----\n lock(\u0026xa-\u003exa_lock#4);\n \u003cInterrupt\u003e\n lock(\u0026xa-\u003exa_lock#4);\n\n *** DEADLOCK ***\n\n 2 locks held by test5/1708:\n #0: ffff888127baa498 (\u0026sb-\u003es_type-\u003ei_mutex_key#22){++++}-{4:4}, at:\n nfs_start_io_read+0x28/0x90 [nfs]\n #1: ffff888127baa650 (mapping.invalidate_lock#3){.+.+}-{4:4}, at:\n page_cache_ra_unbounded+0xa4/0x280\n\n stack backtrace:\n CPU: 6 PID: 1708 Comm: test5 Kdump: loaded Not tainted 6.7.0-lockdbg+\n Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-1.fc39\n04/01/2014\n Call Trace:\n dump_stack_lvl+0x5b/0x90\n mark_lock+0xb3f/0xd20\n __lock_acquire+0x77b/0x3360\n _raw_spin_lock+0x34/0x80\n nfs_netfs_issue_read+0x1b2/0x4b0 [nfs]\n netfs_begin_read+0x77f/0x980 [netfs]\n nfs_netfs_readahead+0x45/0x60 [nfs]\n nfs_readahead+0x323/0x5a0 [nfs]\n read_pages+0xf3/0x5c0\n page_cache_ra_unbounded+0x1c8/0x280\n filemap_get_pages+0x38c/0xae0\n filemap_read+0x206/0x5e0\n nfs_file_read+0xb7/0x140 [nfs]\n vfs_read+0x2a9/0x460\n ksys_read+0xb7/0x140"

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ip_tunnel: make sure to pull inner header in ip_tunnel_rcv()
Apply the same fix than ones found in :
8d975c15c0cd ("ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()")
1ca1ba465e55 ("geneve: make sure to pull inner header in geneve_rx()")
We have to save skb->network_header in a temporary variable
in order to be able to recompute the network_header pointer
after a pskb_inet_may_pull() call.
pskb_inet_may_pull() makes sure the needed headers are in skb->head.

A remote attacker produces the required non-linear skb deterministically by IP-fragmenting the tunnel packet so reassembly leaves the linear area ending at the inner network header.\nAC:L - The attacker fully controls the packet layout: `pskb_may_pull()`/`__pskb_pull_tail()` pull exactly the requested bytes, so a chosen fragment split reliably leaves zero linear bytes at the inner header on every packet, and for gretap/ERSPAN the `pskb_may_pull(ETH_HLEN)` in `__iptunnel_pull_header()` lands the boundary automatically.\nPR:N - GRE and IPIP/SIT have no authentication whatsoever, and `ip_tunnel_lookup()` has wildcard-remote, collect_md and fallback-device passes that match packets from any source address, so no account or credentials on the target are required.\nUI:N - Decapsulation happens automatically in softirq context on packet receipt; no action by any local user or administrator is needed beyond the tunnel already being configured and up.\nS:U - The uninitialized read and the resulting mis-handled packet stay entirely within the kernel\u0027s own security authority; no VM, IOMMU, container or sandbox boundary is crossed.\nC:L - One to two bytes of uninitialized/stale kernel memory past `skb_tail_pointer()` (heap padding or `skb_shared_info` bytes) are read, and their low ECN bits are inferable by the attacker from whether the tunneled packet is delivered or dropped \u2014 a real but strictly bounded, low-bandwidth disclosure oracle rather than arbitrary memory read.\nI:L - No out-of-bounds write is reachable because `INET_ECN_set_ce()`/`INET_ECN_set_ect1()` bounds-check against the tail pointer, but the RFC 6040 decapsulation decision \u2014 whether the congestion (CE) signal is propagated to the inner packet and whether the frame is accepted \u2014 is driven by uninitialized memory, corrupting the ECN state of legitimate decapsulated traffic.\nA:L - The read always stays inside the skb head allocation (`skb_shared_info` follows `skb-\u003eend`), so no oops or panic is reachable on a production kernel; the effect is that legitimate tunneled packets are non-deterministically dropped via the `err \u003e 1` path (`rx_frame_errors`/`rx_errors`), degrading the tunnel rather than the host."

net: esp: fix bad handling of pages from page_pool
When the skb is reorganized during esp_output (!esp->inline), the pages
coming from the original skb fragments are supposed to be released back
to the system through put_page. But if the skb fragment pages are
originating from a page_pool, calling put_page on them will trigger a
page_pool leak which will eventually result in a crash.
This leak can be easily observed when using CONFIG_DEBUG_VM and doing
ipsec + gre (non offloaded) forwarding:

The suggested fix is to introduce a new wrapper (skb_page_unref) that
covers page refcounting for page_pool pages as well.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout
While the rhashtable set gc runs asynchronously, a race allows it to
collect elements from anonymous sets with timeouts while it is being
released from the commit path.
Mingi Cho originally reported this issue in a different path in 6.1.x
with a pipapo set with low timeouts which is not possible upstream since
7395dfacfff6 ("netfilter: nf_tables: use timestamp to check for set
element timeout").
Fix this by setting on the dead flag for anonymous sets to skip async gc
in this case.
According to 08e4c8c5919f ("netfilter: nf_tables: mark newset as dead on
transaction abort"), Florian plans to accelerate abort path by releasing
objects via workqueue, therefore, this sets on the dead flag for abort
path too.

Per kernel scoring guidance, netfilter/nftables netlink paths are Local.\nAC:L - The attacker controls both sides of the race: they create the anonymous meter set, choose the element timeouts that drive the async rhashtable GC worker (which fires every HZ since anonymous sets force gc_int=0), and choose exactly when to issue the rule-delete transaction that unbinds and asynchronously destroys the set. Failed attempts are harmless and the sequence can be repeated indefinitely with many parallel meter sets, so the race is reliably winnable.\nPR:L - The nftables netlink path only checks netlink_net_capable(skb, CAP_NET_ADMIN), which is evaluated against the owning user namespace of the network namespace, so an unprivileged user obtains it with `unshare -Urn` and nf_tables is fully per-netns. No real root in the initial namespace is needed.\nUI:N - The entire sequence \u2014 creating the meter rule, generating traffic to populate the set, and deleting the rule \u2014 is performed by the attacker\u0027s own process. No victim action of any kind is involved.\nS:U - The use-after-free and double-free occur in kernel heap memory within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed. This is a standard kernel-local privilege escalation primitive.\nC:H - The freed nft_rhash_elem objects carry attacker-sized and attacker-controlled key/data, so the UAF permits reallocating the freed slab object with adjacent kernel data and reading it back through set-element dumps (NFT_MSG_GETSETELEM), yielding arbitrary kernel memory disclosure. Per guidance, any use-after-free is scored High.\nI:H - The concurrent GC removal and rhashtable_free_and_destroy() teardown produce a use-after-free and double-free of slab objects whose size and contents the attacker chooses, a well-established nftables heap-corruption primitive (as in CVE-2023-32233 and CVE-2024-1086) that can be groomed into an arbitrary write and full local privilege escalation.\nA:H - Even without successful exploitation, the UAF/double-free on set elements and the destroyed rhashtable bucket table causes slab corruption, list corruption, and kernel oops/panic. Any kernel crash is scored High."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: phy: qcom: at803x: fix kernel panic with at8031_probe
On reworking and splitting the at803x driver, in splitting function of
at803x PHYs it was added a NULL dereference bug where priv is referenced
before it's actually allocated and then is tried to write to for the
is_1000basex and is_fiber variables in the case of at8031, writing on
the wrong address.
Fix this by correctly setting priv local variable only after
at803x_probe is called and actually allocates priv in the phydev struct.

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

No memory layout or victim state outside the attacker\u0027s influence is required.\nPR:N - A kTLS-offloading server accepts connections from arbitrary unauthenticated clients (no client certificates in the typical deployment), and once the session is established the attacker only needs to send record data. No account or privilege on the target system is required.\nUI:N - The bug triggers automatically during normal kTLS record encryption and decryption on an established connection. No action by any local user or administrator is needed.\nS:U - The use-after-free, double free and page refcount underflow all occur within kernel memory managed by the same security authority. No VM, IOMMU or sandbox boundary is crossed.\nC:H - The freed tls_rec / aead_req+tls_decrypt_ctx blocks are re-read after being reclaimed, yielding an attacker-groomable sock pointer and scatterlist, and the page refcount underflow from the spurious put_page() lets freed pages holding other tenants\u0027 data be re-observed. This is leverageable into arbitrary kernel memory disclosure.\nI:H - The stale callback writes into freed memory (rec-\u003etx_ready, sge-\u003eoffset, ctx-\u003easync_wait.err) and the crypto engine writes attacker-supplied plaintext into pages already released, giving a controlled-content write primitive, compounded by a double kfree() of the decrypt buffer.\nA:H - The use-after-free, double free and page refcount underflow reliably produce slab corruption and kernel panics, and the encrypt_pending/decrypt_pending underflow leaves tls_*crypt_async_wait() waiting on a completion that never arrives, hanging the socket close path."

Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: compress: fix reserve_cblocks counting error when out of space
When a file only needs one direct_node, performing the following
operations will cause the file to be unrepairable:
unisoc # ./f2fs_io compress test.apk
unisoc #df -h | grep dm-48
/dev/block/dm-48 112G 112G 1.2M 100% /data
unisoc # ./f2fs_io release_cblocks test.apk
924
unisoc # df -h | grep dm-48
/dev/block/dm-48 112G 112G 4.8M 100% /data
unisoc # dd if=/dev/random of=file4 bs=1M count=3
3145728 bytes (3.0 M) copied, 0.025 s, 120 M/s
unisoc # df -h | grep dm-48
/dev/block/dm-48 112G 112G 1.8M 100% /data
unisoc # ./f2fs_io reserve_cblocks test.apk
F2FS_IOC_RESERVE_COMPRESS_BLOCKS failed: No space left on device
adb reboot
unisoc # df -h | grep dm-48
/dev/block/dm-48 112G 112G 11M 100% /data
unisoc # ./f2fs_io reserve_cblocks test.apk
0
This is because the file has only one direct_node. After returning
to -ENOSPC, reserved_blocks += ret will not be executed. As a result,
the reserved_blocks at this time is still 0, which is not the real
number of reserved blocks. Therefore, fsck cannot be set to repair
the file.
After this patch, the fsck flag will be set to fix this problem.
unisoc # df -h | grep dm-48
/dev/block/dm-48 112G 112G 1.8M 100% /data
unisoc # ./f2fs_io reserve_cblocks test.apk
F2FS_IOC_RESERVE_COMPRESS_BLOCKS failed: No space left on device
adb reboot then fsck will be executed
unisoc # df -h | grep dm-48
/dev/block/dm-48 112G 112G 11M 100% /data
unisoc # ./f2fs_io reserve_cblocks test.apk

Summary
In the Linux kernel, the following vulnerability has been resolved:
wireguard: netlink: check for dangling peer via is_dead instead of empty list
If all peers are removed via wg_peer_remove_all(), rather than setting
peer_list to empty, the peer is added to a temporary list with a head on
the stack of wg_peer_remove_all(). If a netlink dump is resumed and the
cursored peer is one that has been removed via wg_peer_remove_all(), it
will iterate from that peer and then attempt to dump freed peers.
Fix this by instead checking peer->is_dead, which was explictly created
for this purpose. Also move up the device_update_lock lockdep assertion,
since reading is_dead relies on that.
It can be reproduced by a small script like:
echo "Setting config..."
ip link add dev wg0 type wireguard
wg setconf wg0 /big-config
(
while true; do
echo "Showing config..."
wg showconf wg0 > /dev/null
done
) &
sleep 4
wg setconf wg0 <(printf "[Peer]\nPublicKey=$(wg genkey)\n")
Resulting in:

Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio: packed: fix unmap leak for indirect desc table
When use_dma_api and premapped are true, then the do_unmap is false.
Because the do_unmap is false, vring_unmap_extra_packed is not called by
detach_buf_packed.
if (unlikely(vq->do_unmap)) {
curr = id;
for (i = 0; i < state->num; i++) {
vring_unmap_extra_packed(vq,
&vq->packed.desc_extra[curr]);
curr = vq->packed.desc_extra[curr].next;
}
}
So the indirect desc table is not unmapped. This causes the unmap leak.
So here, we check vq->use_dma_api instead. Synchronously, dma info is
updated based on use_dma_api judgment
This bug does not occur, because no driver use the premapped with
indirect.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/bnx2x: Prevent access to a freed page in page_pool
Fix race condition leading to system crash during EEH error handling
During EEH error recovery, the bnx2x driver's transmit timeout logic
could cause a race condition when handling reset tasks. The
bnx2x_tx_timeout() schedules reset tasks via bnx2x_sp_rtnl_task(),
which ultimately leads to bnx2x_nic_unload(). In bnx2x_nic_unload()
SGEs are freed using bnx2x_free_rx_sge_range(). However, this could
overlap with the EEH driver's attempt to reset the device using
bnx2x_io_slot_reset(), which also tries to free SGEs. This race
condition can result in system crashes due to accessing freed memory
locations in bnx2x_free_rx_sge()
799 static inline void bnx2x_free_rx_sge(struct bnx2x *bp,
800 struct bnx2x_fastpath *fp, u16 index)
801 {
802 struct sw_rx_page *sw_buf = &fp->rx_page_ring[index];
803 struct page *page = sw_buf->page;
....
where sw_buf was set to NULL after the call to dma_unmap_page()
by the preceding thread.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/bios: Tolerate devdata==NULL in intel_bios_encoder_supports_dp_dual_mode()
If we have no VBT, or the VBT didn't declare the encoder
in question, we won't have the 'devdata' for the encoder.
Instead of oopsing just bail early.
We won't be able to tell whether the port is DP++ or not,
but so be it.
