Summary
In the Linux kernel, the following vulnerability has been resolved:
nbd: fix incomplete validation of ioctl arg
We tested and found an alarm caused by nbd_ioctl arg without verification.
The UBSAN warning calltrace like below:
UBSAN: Undefined behaviour in fs/buffer.c:1709:35
signed integer overflow:
-9223372036854775808 - 1 cannot be represented in type 'long long int'
CPU: 3 PID: 2523 Comm: syz-executor.0 Not tainted 4.19.90 #1
Hardware name: linux,dummy-virt (DT)

The reason for triggering this warning is __block_write_full_page()
-> i_size_read(inode) - 1 overflow.
inode->i_size is assigned in __nbd_ioctl() -> nbd_set_size() -> bytesize.
We think it is necessary to limit the size of arg to prevent errors.
Moreover, __nbd_ioctl() -> nbd_add_socket(), arg will be cast to int.
Assuming the value of arg is 0x80000000000000001) (on a 64-bit machine),
it will become 1 after the coercion, which will return unexpected results.
Fix it by adding checks to prevent passing in too large numbers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommufd: Fix race during abort for file descriptors
fput() doesn't actually call file_operations release() synchronously, it
puts the file on a work queue and it will be released eventually.
This is normally fine, except for iommufd the file and the iommufd_object
are tied to gether. The file has the object as it's private_data and holds
a users refcount, while the object is expected to remain alive as long as
the file is.
When the allocation of a new object aborts before installing the file it
will fput() the file and then go on to immediately kfree() the obj. This
causes a UAF once the workqueue completes the fput() and tries to
decrement the users refcount.
Fix this by putting the core code in charge of the file lifetime, and call
__fput_sync() during abort to ensure that release() is called before
kfree. __fput_sync() is a bit too tricky to open code in all the object
implementations. Instead the objects tell the core code where the file
pointer is and the core will take care of the life cycle.
If the object is successfully allocated then the file will hold a users
refcount and the iommufd_object cannot be destroyed.
It is worth noting that close(); ioctl(IOMMU_DESTROY); doesn't have an
issue because close() is already using a synchronous version of fput().
The UAF looks like this:

Instead the objects tell the core code where the file\npointer is and the core will take care of the life cycle.\n\nIf the object is successfully allocated then the file will hold a users\nrefcount and the iommufd_object cannot be destroyed.\n\nIt is worth noting that close(); ioctl(IOMMU_DESTROY); doesn\u0027t have an\nissue because close() is already using a synchronous version of fput().\n\nThe UAF looks like this:\n\n BUG: KASAN: slab-use-after-free in iommufd_eventq_fops_release+0x45/0xc0 drivers/iommu/iommufd/eventq.c:376\n Write of size 4 at addr ffff888059c97804 by task syz.0.46/6164\n\n CPU: 0 UID: 0 PID: 6164 Comm: syz.0.46 Not tainted syzkaller #0 PREEMPT(full)\n Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 08/18/2025\n Call Trace:\n \u003cTASK\u003e\n __dump_stack lib/dump_stack.c:94 [inline]\n dump_stack_lvl+0x116/0x1f0 lib/dump_stack.c:120\n print_address_description mm/kasan/report.c:378 [inline]\n print_report+0xcd/0x630 mm/kasan/report.c:482\n kasan_report+0xe0/0x110 mm/kasan/report.c:595\n check_region_inline mm/kasan/generic.c:183 [inline]\n kasan_check_range+0x100/0x1b0 mm/kasan/generic.c:189\n instrument_atomic_read_write include/linux/instrumented.h:96 [inline]\n atomic_fetch_sub_release include/linux/atomic/atomic-instrumented.h:400 [inline]\n __refcount_dec include/linux/refcount.h:455 [inline]\n refcount_dec include/linux/refcount.h:476 [inline]\n iommufd_eventq_fops_release+0x45/0xc0 drivers/iommu/iommufd/eventq.c:376\n __fput+0x402/0xb70 fs/file_table.c:468\n task_work_run+0x14d/0x240 kernel/task_work.c:227\n resume_user_mode_work include/linux/resume_user_mode.h:50 [inline]\n exit_to_user_mode_loop+0xeb/0x110 kernel/entry/common.c:43\n exit_to_user_mode_prepare include/linux/irq-entry-common.h:225 [inline]\n syscall_exit_to_user_mode_work include/linux/entry-common.h:175 [inline]\n syscall_exit_to_user_mode include/linux/entry-common.h:210 [inline]\n do_syscall_64+0x41c/0x4c0 arch/x86/entry/syscall_64.c:100\n entry_SYSCALL_64_after_hwframe+0x77/0x7f"

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs: fix UAF/GPF bug in nilfs_mdt_destroy
In alloc_inode, inode_init_always() could return -ENOMEM if
security_inode_alloc() fails, which causes inode->i_private
uninitialized. Then nilfs_is_metadata_file_inode() returns
true and nilfs_free_inode() wrongly calls nilfs_mdt_destroy(),
which frees the uninitialized inode->i_private
and leads to crashes(e.g., UAF/GPF).
Fix this by moving security_inode_alloc just prior to
this_cpu_inc(nr_inodes)

Summary
In the Linux kernel, the following vulnerability has been resolved:
clone_private_mnt(): make sure that caller has CAP_SYS_ADMIN in the right userns
What we want is to verify there is that clone won't expose something
hidden by a mount we wouldn't be able to undo. "Wouldn't be able to undo"
may be a result of MNT_LOCKED on a child, but it may also come from
lacking admin rights in the userns of the namespace mount belongs to.
clone_private_mnt() checks the former, but not the latter.
There's a number of rather confusing CAP_SYS_ADMIN checks in various
userns during the mount, especially with the new mount API; they serve
different purposes and in case of clone_private_mnt() they usually,
but not always end up covering the missing check mentioned above.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: fix zswap writeback race condition
The zswap writeback mechanism can cause a race condition resulting in
memory corruption, where a swapped out page gets swapped in with data that
was written to a different page.
The race unfolds like this:
1. a page with data A and swap offset X is stored in zswap
2. page A is removed off the LRU by zpool driver for writeback in
zswap-shrink work, data for A is mapped by zpool driver
3. user space program faults and invalidates page entry A, offset X is
considered free
4. kswapd stores page B at offset X in zswap (zswap could also be
full, if so, page B would then be IOed to X, then skip step 5.)
5. entry A is replaced by B in tree->rbroot, this doesn't affect the
local reference held by zswap-shrink work
6. zswap-shrink work writes back A at X, and frees zswap entry A
7. swapin of slot X brings A in memory instead of B
The fix:
Once the swap page cache has been allocated (case ZSWAP_SWAPCACHE_NEW),
zswap-shrink work just checks that the local zswap_entry reference is
still the same as the one in the tree. If it's not the same it means that
it's either been invalidated or replaced, in both cases the writeback is
aborted because the local entry contains stale data.
Reproducer:
I originally found this by running `stress` overnight to validate my work
on the zswap writeback mechanism, it manifested after hours on my test
machine. The key to make it happen is having zswap writebacks, so
whatever setup pumps /sys/kernel/debug/zswap/written_back_pages should do
the trick.
In order to reproduce this faster on a vm, I setup a system with ~100M of
available memory and a 500M swap file, then running `stress --vm 1
--vm-bytes 300000000 --vm-stride 4000` makes it happen in matter of tens
of minutes. One can speed things up even more by swinging
/sys/module/zswap/parameters/max_pool_percent up and down between, say, 20
and 1; this makes it reproduce in tens of seconds. It's crucial to set
`--vm-stride` to something other than 4096 otherwise `stress` won't
realize that memory has been corrupted because all pages would have the
same data.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm: fix zswap writeback race condition\n\nThe zswap writeback mechanism can cause a race condition resulting in\nmemory corruption, where a swapped out page gets swapped in with data that\nwas written to a different page.\n\nThe race unfolds like this:\n1. a page with data A and swap offset X is stored in zswap\n2. page A is removed off the LRU by zpool driver for writeback in\n zswap-shrink work, data for A is mapped by zpool driver\n3. user space program faults and invalidates page entry A, offset X is\n considered free\n4. kswapd stores page B at offset X in zswap (zswap could also be\n full, if so, page B would then be IOed to X, then skip step 5.)\n5. entry A is replaced by B in tree-\u003erbroot, this doesn\u0027t affect the\n local reference held by zswap-shrink work\n6. zswap-shrink work writes back A at X, and frees zswap entry A\n7. swapin of slot X brings A in memory instead of B\n\nThe fix:\nOnce the swap page cache has been allocated (case ZSWAP_SWAPCACHE_NEW),\nzswap-shrink work just checks that the local zswap_entry reference is\nstill the same as the one in the tree. If it\u0027s not the same it means that\nit\u0027s either been invalidated or replaced, in both cases the writeback is\naborted because the local entry contains stale data.\n\nReproducer:\nI originally found this by running `stress` overnight to validate my work\non the zswap writeback mechanism, it manifested after hours on my test\nmachine. The key to make it happen is having zswap writebacks, so\nwhatever setup pumps /sys/kernel/debug/zswap/written_back_pages should do\nthe trick.\n\nIn order to reproduce this faster on a vm, I setup a system with ~100M of\navailable memory and a 500M swap file, then running `stress --vm 1\n--vm-bytes 300000000 --vm-stride 4000` makes it happen in matter of tens\nof minutes. One can speed things up even more by swinging\n/sys/module/zswap/parameters/max_pool_percent up and down between, say, 20\nand 1; this makes it reproduce in tens of seconds. It\u0027s crucial to set\n`--vm-stride` to something other than 4096 otherwise `stress` won\u0027t\nrealize that memory has been corrupted because all pages would have the\nsame data."

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

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: slab-out-of-bounds read in brcmf_get_assoc_ies()
Fix a slab-out-of-bounds read that occurs in kmemdup() called from
brcmf_get_assoc_ies().
The bug could occur when assoc_info->req_len, data from a URB provided
by a USB device, is bigger than the size of buffer which is defined as
WL_EXTRA_BUF_MAX.
Add the size check for req_len/resp_len of assoc_info.
Found by a modified version of syzkaller.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: seqiv - Handle EBUSY correctly
As it is seqiv only handles the special return value of EINPROGERSS,
which means that in all other cases it will free data related to the
request.
However, as the caller of seqiv may specify MAY_BACKLOG, we also need
to expect EBUSY and treat it in the same way. Otherwise backlogged
requests will trigger a use-after-free.

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

Repo precedent (CVE-2026-43414, qla2xxx FC) scores FC-peer-triggered driver memory corruption as Network.\nAC:L - The remote initiator controls both sides of the race \u2014 it forces the deferred path by flooding the queue past its fod count (-EOVERFLOW) and drives lpfc_nvmet_ctxbuf_post() concurrently by sending ABTS for the same exchange \u2014 and can retry at FC line rate until the unlocked free/clear window is hit.\nPR:N - NVMe/FC provides no transport authentication and no TLS; hostnqn-based allow-lists are an authorization filter that a fabric-attached attacker can spoof, and ABTS frames reaching lpfc_nvmet_rcv_unsol_abort() require no established association at all. No privileges on the target host are needed.\nUI:N - The race is triggered entirely by inbound FC frames processed asynchronously in the driver\u0027s interrupt/completion and workqueue contexts. No administrator or user action on the target system is required.\nS:U - The double-free and use-after-free corrupt kernel heap and DMA-pool state within the target host\u0027s own kernel security authority.

Heap grooming around the freed slab object yields an arbitrary-read primitive.\nI:H - lpfc_rq_buf_free() performs a list_del() write into the freed object and re-posts stale DMA addresses to the hardware RQ, causing the HBA to DMA attacker-supplied FC frame content into freed/reallocated kernel memory \u2014 a remote, attacker-controlled kernel write primitive, plus double-free-based heap control.\nA:H - The double kfree()/dma_pool_free() and freed-list corruption reliably produce slab corruption, BUG_ON in the allocator, or an oops in the interrupt-context completion handler, panicking the storage target host."

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Protect against send buffer overflow in NFSv2 READ
Since before the git era, NFSD has conserved the number of pages
held by each nfsd thread by combining the RPC receive and send
buffers into a single array of pages. This works because there are
no cases where an operation needs a large RPC Call message and a
large RPC Reply at the same time.
Once an RPC Call has been received, svc_process() updates
svc_rqst::rq_res to describe the part of rq_pages that can be
used for constructing the Reply. This means that the send buffer
(rq_res) shrinks when the received RPC record containing the RPC
Call is large.
A client can force this shrinkage on TCP by sending a correctly-
formed RPC Call header contained in an RPC record that is
excessively large. The full maximum payload size cannot be
constructed in that case.

"value": "AV:A - The vulnerable path is reached when a Bluetooth LE peer sends an L2CAP Command Reject on the LE signaling CID (hci_rx_work \u2192 l2cap_recv_acldata \u2192 l2cap_le_sig_channel \u2192 l2cap_le_command_rej), which requires adjacency on the Bluetooth radio segment.\nAC:L - An attacker who is the LE peer can send COMMAND_REJ with the ident from a pending LE CoC request and reliably hit the missing hold/put window; no conditions beyond the attacker\u0027s control are required.\nPR:N - LE ACL/L2CAP signaling is processed for an established HCI LE connection with no pairing, encryption, or local capability check before l2cap_le_command_rej runs.\nUI:N - Exploitation only needs an LE link and a matching pending channel ident; no additional victim action is required at exploit time once the stack is in that normal operational state.\nS:U - Impact is confined to the local kernel Bluetooth/L2CAP authority (memory corruption / privilege escalation on the host), with no cross-boundary escape.\nC:H - This is a use-after-free of struct l2cap_chan; UAF enables heap reuse and arbitrary kernel read primitives.\nI:H - The same UAF enables heap spraying and arbitrary write / control-flow hijacking in kernel context.\nA:H - Dereferencing the freed channel (e.g., in l2cap_chan_unlock after l2cap_chan_del) can oops/panic the kernel even without full exploitation."

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix mlx5_ib_get_hw_stats when used for device
Currently, when mlx5_ib_get_hw_stats() is used for device (port_num = 0),
there is a special handling in order to use the correct counters, but,
port_num is being passed down the stack without any change. Also, some
functions assume that port_num >=1. As a result, the following oops can
occur.
BUG: unable to handle page fault for address: ffff89510294f1a8
#PF: supervisor write access in kernel mode

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

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

flags of an uninitialized page. So VM_BUG_ON_PAGE(PagePoisoned(page)) is
triggered. This can be reproduced by below steps:
1.Offline memory block:
echo offline > /sys/devices/system/memory/memory12/state
2.Get offlined memory pfn:
page-types -b n -rlN
3.Write pfn to unpoison-pfn
echo <pfn> > /sys/kernel/debug/hwpoison/unpoison-pfn
This scenario can be identified by pfn_to_online_page() returning NULL.
And ZONE_DEVICE pages are never expected, so we can simply fail if
pfn_to_online_page() == NULL to fix the bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix race with concurrent opens in rename(2)
Besides sending the rename request to the server, the rename process
also involves closing any deferred close, waiting for outstanding I/O
to complete as well as marking all existing open handles as deleted to
prevent them from deferring closes, which increases the race window
for potential concurrent opens on the target file.
Fix this by unhashing the dentry in advance to prevent any concurrent
opens on the target.

No network peer initiates the attack; a remote SMB server can only widen the window by delaying responses.\nAC:L - The attacker owns both sides of the race and the window is enormous \u2014 it spans an unbounded `netfs_wait_for_outstanding_io()` wait, deferred-close teardown, and a full SMB round trip plus a 3-iteration retry loop. The attacker can widen it arbitrarily by keeping I/O outstanding on the target, making it trivially winnable with a simple rename/open loop.\nPR:L - Any unprivileged local user with ordinary access to a directory on an already-mounted CIFS/SMB share can call rename(2) and open(2); no capabilities are required. Mounted SMB shares are routine on enterprise desktops, autofs home directories, and containers with CIFS volumes.\nUI:N - Both racing threads are the attacker\u0027s own; no victim action is needed. The presence of an SMB mount is a standing system configuration, not a per-exploit user interaction.\nS:U - The corruption of dcache/deferred-handle state and the resulting file damage stay entirely within the kernel and the mounted filesystem\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - A handle opened inside the race escapes `cifs_mark_open_handles_for_deleted_file()` and remains on `tcon-\u003eopenFileList`, where `cifs_get_readable_path()` matches cached handles by path string \u2014 so a later `open(2)`/`read(2)` of that path can be served from the stale handle to the pre-rename file, disclosing unbounded contents of a file (potentially another user\u0027s) that should no longer be reachable at that name.\nI:H - The racing open makes the target appear busy, driving `cifs_rename2()` into the `unlink_target:` path that deletes the target file and retries \u2014 on retry failure the file\u0027s data is destroyed while rename(2) reports an error (the documented data-loss mode fixed by the later `c5ea3065586d`). The same stale path-matched handle also lets writes land on the wrong server-side object.\nA:H - By keeping opens and I/O active on the still-hashed target, the attacker prevents `netfs_wait_for_outstanding_io()`\u0027s `io_count` from ever reaching zero, pinning the renaming task in unkillable uninterruptible sleep while it holds the parent directory\u0027s `i_rwsem` exclusively \u2014 starving all other operations in that directory and triggering hung-task warnings (panic with `hung_task_panic=1`)."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix an out-of-bounds bug in __snd_usb_parse_audio_interface()
There may be a bad USB audio device with a USB ID of (0x04fa, 0x4201) and
the number of it's interfaces less than 4, an out-of-bounds read bug occurs
when parsing the interface descriptor for this device.
Fix this by checking the number of interfaces.

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: Don't call reqsk_fastopen_remove() in tcp_conn_request().
syzbot reported the splat below in tcp_conn_request(). [0]
If a listener is close()d while a TFO socket is being processed in
tcp_conn_request(), inet_csk_reqsk_queue_add() does not set reqsk->sk
and calls inet_child_forget(), which calls tcp_disconnect() for the
TFO socket.
After the cited commit, tcp_disconnect() calls reqsk_fastopen_remove(),
where reqsk_put() is called due to !reqsk->sk.
Then, reqsk_fastopen_remove() in tcp_conn_request() decrements the
last req->rsk_refcnt and frees reqsk, and __reqsk_free() at the
drop_and_free label causes the refcount underflow for the listener
and double-free of the reqsk.
Let's remove reqsk_fastopen_remove() in tcp_conn_request().
Note that other callers make sure tp->fastopen_rsk is not NULL.
[0]:
refcount_t: underflow; use-after-free.

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sched: sfb: fix null pointer access issue when sfb_init() fails
When the default qdisc is sfb, if the qdisc of dev_queue fails to be
inited during mqprio_init(), sfb_reset() is invoked to clear resources.
In this case, the q->qdisc is NULL, and it will cause gpf issue.
The process is as follows:
qdisc_create_dflt()
sfb_init()
tcf_block_get() --->failed, q->qdisc is NULL
...
qdisc_put()
...
sfb_reset()
qdisc_reset(q->qdisc) --->q->qdisc is NULL
ops = qdisc->ops
The following is the Call Trace information:
general protection fault, probably for non-canonical address
0xdffffc0000000003: 0000 [#1] PREEMPT SMP KASAN

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
efivarfs: Fix slab-out-of-bounds in efivarfs_d_compare
Observed on kernel 6.6 (present on master as well):
BUG: KASAN: slab-out-of-bounds in memcmp+0x98/0xd0
Call trace:
kasan_check_range+0xe8/0x190
__asan_loadN+0x1c/0x28
memcmp+0x98/0xd0
efivarfs_d_compare+0x68/0xd8
__d_lookup_rcu_op_compare+0x178/0x218
__d_lookup_rcu+0x1f8/0x228
d_alloc_parallel+0x150/0x648

do_filp_open+0x114/0x248
do_sys_openat2+0x340/0x3c0
__arm64_sys_openat+0x120/0x1a0
If dentry->d_name.len < EFI_VARIABLE_GUID_LEN , 'guid' can become
negative, leadings to oob. The issue can be triggered by parallel
lookups using invalid filename:
T1 T2
lookup_open
->lookup
simple_lookup
d_add
// invalid dentry is added to hash list
lookup_open
d_alloc_parallel
__d_lookup_rcu
__d_lookup_rcu_op_compare
hlist_bl_for_each_entry_rcu
// invalid dentry can be retrieved
->d_compare
efivarfs_d_compare
// oob
Fix it by checking 'guid' before cmp.

"value": "AV:L - The vulnerable `efivarfs_d_compare()` is reached only through local path-lookup syscalls (`openat`/`stat`) against the efivarfs mount at /sys/firmware/efi/efivars. There is no network or remote-peer input path into the dcache lookup for this filesystem.\nAC:L - `efivarfs_d_hash()` makes every name shorter than 36 bytes hash to the same value, so the attacker deterministically constructs the bucket collision and length match rather than guessing them, and both sides of the parallel-lookup race are attacker threads that can retry in a tight loop indefinitely. No condition outside the attacker\u0027s control is required.\nPR:L - The efivarfs root directory is mode 0755 and lookup requires only MAY_EXEC, so any unprivileged local user can issue the two concurrent `openat()` calls; `-\u003elookup` is `simple_lookup` with no name validation and no write permission needed. No capability, and no root, is involved.\nUI:N - The attacker drives both racing lookups themselves with no victim participation. efivarfs being mounted is a default-deployment property of UEFI systems (systemd mounts it at boot), not an action a user must be tricked into performing.\nS:U - The out-of-bounds read stays within kernel slab memory under the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The negative `guid` is promoted to a ~2^64 `size_t`, giving a length-unbounded read that walks past the `dentry_cache` object into arbitrary adjacent kernel heap memory, and the attacker controls the comparison bytes on both sides so the early-exit point of `memcmp` acts as an oracle on that memory. Per kernel guidance an unbounded OOB read scores High.\nI:N - `efivarfs_d_compare()` performs only `memcmp`/`strncasecmp` reads and writes nothing; a false dentry match that could redirect a lookup to the wrong EFI variable would require ~2^64 consecutive matching bytes, which faults long before it could occur.\nA:H - The KASAN trace in the fix commit documents a slab-out-of-bounds abort, and the unbounded read readily runs off the slab page into unmapped memory, producing an oops or panic (and an immediate panic under KASAN/panic_on_oops). The attacker can retrigger it at will from an unprivileged loop."

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

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

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

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Avoid calling OPDESC() with ops->opnum == OP_ILLEGAL
OPDESC() simply indexes into nfsd4_ops[] by the op's operation
number, without range checking that value. It assumes callers are
careful to avoid calling it with an out-of-bounds opnum value.
nfsd4_decode_compound() is not so careful, and can invoke OPDESC()
with opnum set to OP_ILLEGAL, which is 10044 -- well beyond the end
of nfsd4_ops[].

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

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

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

"value": "AV:L - The vulnerable code is in the NFS client\u0027s buffered-write path and is reached through local `write(2)`/mmap dirtying plus writeback-forcing syscalls (`fsync`, `sync_file_range`, `ftruncate`); a purely remote party cannot create the required local writer, though a malicious NFS server can precisely time the racing removal side via its RPC replies.\nAC:L - The attacker controls both sides of the race \u2014 one thread issues overlapping buffered writes to the same folio while another forces writeback/invalidation \u2014 and can retry the loop indefinitely with no precondition outside their control; server-induced short writes or errors widen the window further.\nPR:L - Only an unprivileged local account with write access to any file on an NFS mount is required, which is the norm on NFS-backed home directories, HPC scratch, and container/Kubernetes NFS volumes.\nUI:N - The attacker\u0027s own process performs all the writes, writeback triggers, and truncation; no action by any other user is needed beyond the NFS mount already existing.\nS:U - The corruption and resulting crash are confined to the kernel\u0027s own security authority on the affected host; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Detaching the folio from NFS\u0027s private bookkeeping while requests are still live breaks the writeback-state invariant, allowing mismatched `folio_start/end_writeback` and stale `req-\u003ewb_head`/folio references so freed or recycled page contents can be transmitted to the server and read back, and truncated-mapping pointers are dereferenced.\nI:H - Writes acknowledged to userspace are silently discarded \u2014 the merged request is detached and freed while the folio\u0027s dirty bit is consumed by writeback with no RPC sent \u2014 corrupting NFS file data for any process on the client, and kernel request/refcount/`nrequests` state is left inconsistent.\nA:H - The zombie request lets the folio be truncated or reclaimed with `folio-\u003emapping` set to NULL while completion paths unconditionally dereference `folio-\u003emapping-\u003ehost` (`nfs_page_to_inode`, `nfs_inode_remove_request`, `nfs_folio_end_writeback`), producing a kernel oops, and the `WARN_ON_ONCE` splats panic systems running `panic_on_warn`."
