Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: lzo - Fix compression buffer overrun
Unlike the decompression code, the compression code in LZO never
checked for output overruns. It instead assumes that the caller
always provides enough buffer space, disregarding the buffer length
provided by the caller.
Add a safe compression interface that checks for the end of buffer
before each write. Use the safe interface in crypto/lzo.

There is no race, no unknown memory layout dependency, and lzo/lzo-rle is a default compressor for zram and UBIFS, so this is fully deterministic and repeatable.\nPR:L - Any unprivileged local user can allocate and dirty memory that gets compressed by zswap/zram, or write file data on a mounted UBIFS volume \u2014 no capabilities, namespaces, or filesystem admin rights are needed. Only local account access is required, hence Low rather than None.\nUI:N - The attacker drives the whole sequence themselves by generating memory pressure or issuing writes; no victim action, mount, or file open by another user is involved.\nS:U - The out-of-bounds write corrupts kernel heap/vmalloc memory within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - An out-of-bounds heap write of attacker-controlled bytes can corrupt adjacent slab objects\u0027 pointers and length fields, which is a well-established route to arbitrary kernel memory disclosure; the over-long compressed stream is also stored and read back, allowing adjacent memory to be recovered on decompression.\nI:H - This is an out-of-bounds write whose overflowing bytes are verbatim copies of attacker-supplied input (the `COPY8` literal loop), giving precise control over the corrupting data and thus a strong heap-corruption primitive suitable for control-flow hijacking and privilege escalation.\nA:H - Overrunning the per-CPU vmalloc scratch buffer hits a guard page for an immediate oops, and slab overflows trip redzone/freelist checks or corrupt allocator metadata, causing kernel panic \u2014 repeatably, from an unprivileged process."

Commit c28c15b6d28a ("powerpc/code-patching: Use temporary mm for
Radix MMU") is inspired from x86 but unlike x86 is doesn't disable
KASAN reports during patching. This wasn't a problem at the begining
because __patch_mem() is not instrumented.
Commit 465cabc97b42 ("powerpc/code-patching: introduce
patch_instructions()") use copy_to_kernel_nofault() to copy several
instructions at once. But when using temporary mm the destination is
not regular kernel memory but a kind of kernel-like memory located
in user address space.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Load DR6 with guest value only before entering .vcpu_run() loop
Move the conditional loading of hardware DR6 with the guest's DR6 value
out of the core .vcpu_run() loop to fix a bug where KVM can load hardware
with a stale vcpu->arch.dr6.
When the guest accesses a DR and host userspace isn't debugging the guest,
KVM disables DR interception and loads the guest's values into hardware on
VM-Enter and saves them on VM-Exit. This allows the guest to access DRs
at will, e.g. so that a sequence of DR accesses to configure a breakpoint
only generates one VM-Exit.
For DR0-DR3, the logic/behavior is identical between VMX and SVM, and also
identical between KVM_DEBUGREG_BP_ENABLED (userspace debugging the guest)
and KVM_DEBUGREG_WONT_EXIT (guest using DRs), and so KVM handles loading
DR0-DR3 in common code, _outside_ of the core kvm_x86_ops.vcpu_run() loop.
But for DR6, the guest's value doesn't need to be loaded into hardware for
KVM_DEBUGREG_BP_ENABLED, and SVM provides a dedicated VMCB field whereas
VMX requires software to manually load the guest value, and so loading the
guest's value into DR6 is handled by {svm,vmx}_vcpu_run(), i.e. is done
_inside_ the core run loop.
Unfortunately, saving the guest values on VM-Exit is initiated by common
x86, again outside of the core run loop. If the guest modifies DR6 (in
hardware, when DR interception is disabled), and then the next VM-Exit is
a fastpath VM-Exit, KVM will reload hardware DR6 with vcpu->arch.dr6 and
clobber the guest's actual value.
The bug shows up primarily with nested VMX because KVM handles the VMX
preemption timer in the fastpath, and the window between hardware DR6
being modified (in guest context) and DR6 being read by guest software is
orders of magnitude larger in a nested setup. E.g. in non-nested, the
VMX preemption timer would need to fire precisely between #DB injection
and the #DB handler's read of DR6, whereas with a KVM-on-KVM setup, the
window where hardware DR6 is "dirty" extends all the way from L1 writing
DR6 to VMRESUME (in L1).

Summary
In the Linux kernel, the following vulnerability has been resolved:
memcg: fix soft lockup in the OOM process
A soft lockup issue was found in the product with about 56,000 tasks were
in the OOM cgroup, it was traversing them when the soft lockup was
triggered.

This is because thousands of processes are in the OOM cgroup, it takes a
long time to traverse all of them. As a result, this lead to soft lockup
in the OOM process.
To fix this issue, call 'cond_resched' in the 'mem_cgroup_scan_tasks'
function per 1000 iterations. For global OOM, call
'touch_softlockup_watchdog' per 1000 iterations to avoid this issue.

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring/kbuf: reallocate buf lists on upgrade
IORING_REGISTER_PBUF_RING can reuse an old struct io_buffer_list if it
was created for legacy selected buffer and has been emptied. It violates
the requirement that most of the field should stay stable after publish.
Always reallocate it instead.

No capability check exists on the write/writeback path.\nUI:N - The OrangeFS mount is an existing part of the deployment, not something the attacker must convince a victim to establish; exploitation is entirely self-driven by the attacker\u0027s own file writes and fsync.\nS:U - The out-of-bounds read and write occur within kernel memory under the same security authority as the vulnerable component; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The multi-gigabyte bvec makes iterate_bvec() walk adjacent struct pages past the single dirty page, copying arbitrary kernel and other-process memory into the OrangeFS shared bufmap, which is mmap\u0027d by the userspace pvfs2-client-core process and transmitted to the OrangeFS server \u2014 a large-scale kernel memory disclosure.\nI:H - orangefs_bufmap_copy_from_iovec() loops with no bound on the descriptor index, reading to-\u003epage_array[i] far past the end of the kmalloc\u0027d array and using the resulting wild struct page pointers as copy_page_from_iter() destinations, giving an out-of-bounds kernel write of attacker-controlled page-cache data.\nA:H - Dereferencing garbage struct page pointers and kmapping invalid PFNs across gigabytes of address space reliably produces a kernel oops or panic; the spurious WARN_ON()s also panic outright under panic_on_warn."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Disable MACsec offload for uplink representor profile
MACsec offload is not supported in switchdev mode for uplink
representors. When switching to the uplink representor profile, the
MACsec offload feature must be cleared from the netdevice's features.
If left enabled, attempts to add offloads result in a null pointer
dereference, as the uplink representor does not support MACsec offload
even though the feature bit remains set.
Clear NETIF_F_HW_MACSEC in mlx5e_fix_uplink_rep_features().

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: cacheinfo: Avoid out-of-bounds write to cacheinfo array
The loop that detects/populates cache information already has a bounds
check on the array size but does not account for cache levels with
separate data/instructions cache. Fix this by incrementing the index
for any populated leaf (instead of any populated level).

Summary
In the Linux kernel, the following vulnerability has been resolved:
partitions: mac: fix handling of bogus partition table
Fix several issues in partition probing:
- The bailout for a bad partoffset must use put_dev_sector(), since the
preceding read_part_sector() succeeded.
- If the partition table claims a silly sector size like 0xfff bytes
(which results in partition table entries straddling sector boundaries),
bail out instead of accessing out-of-bounds memory.
- We must not assume that the partition table contains proper NUL
termination - use strnlen() and strncmp() instead of strlen() and
strcmp().

Physical media insertion is one route, but the loop-device path makes plain local access sufficient, which is the broader and more severe vector.\nAC:L - The attacker fully controls `block_size` and every partition-entry offset in the image, so the straddling out-of-bounds access is deterministic on every probe \u2014 no race, no unknown memory state, no retry needed. CONFIG_MAC_PARTITION is enabled by default in mainstream distro kernels, so no rare configuration is required.\nPR:L - `loop_configure()`/`LOOP_SET_FD` with LO_FLAGS_PARTSCAN performs no capability check \u2014 an unprivileged user holding an open fd on a loop device can bind an arbitrary crafted image file and force the scan. Container, appliance, and sandbox deployments routinely expose loop or removable block devices to non-root users.\nUI:N - The attacker supplies and attaches the malicious image itself and triggers the partition rescan directly; no victim needs to mount, open, or otherwise interact with anything. Hotplug scanning likewise runs automatically at add_disk() with no user action.\nS:U - The out-of-bounds read and write stay within the kernel\u0027s own address space and are handled by the same security authority that owns the block layer. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - Up to 135 bytes of kernel memory past the end of a page-cache folio are read, and those bytes are propagated into partition start/size values that are exposed world-readable through /proc/partitions and sysfs, giving a repeatable kernel-heap disclosure primitive. The read is not narrowly bounded and the attacker chooses the exact offset past the page via secsize and slot.\nI:H - On CONFIG_PPC_PMAC (where MAC_PARTITION is default-y) mac_fix_string() writes NUL bytes into memory beyond the folio at an attacker-chosen offset, an out-of-bounds write into adjacent kernel heap. Kernel partition state is additionally constructed from out-of-bounds memory contents.\nA:H - Reading and writing past the end of a page-cache folio can fault or corrupt adjacent kernel structures, producing an oops or panic (and an immediate KASAN-detected fault on hardened kernels). The missing put_dev_sector() also leaks a folio reference on every bogus-partoffset probe, permanently pinning page-cache pages under repeated triggering."

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: ctucanfd: handle skb allocation failure
If skb allocation fails, the pointer to struct can_frame is NULL. This
is actually handled everywhere inside ctucan_err_interrupt() except for
the only place.
Add the missed NULL check.
Found by Linux Verification Center (linuxtesting.org) with SVACE static
analysis tool.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: cx231xx: set device_caps for 417
The video_device for the MPEG encoder did not set device_caps.
Add this, otherwise the video device can't be registered (you get a
WARN_ON instead).
Not seen before since currently 417 support is disabled, but I found
this while experimenting with it.

==================================================================
f8 corresponds to KASAN_VMALLOC_INVALID which means the area is not
initialised hence not supposed to be used yet.
Powerpc text patching infrastructure allocates a virtual memory area
using get_vm_area() and flags it as VM_ALLOC. But that flag is meant
to be used for vmalloc() and vmalloc() allocated memory is not
supposed to be used before a call to __vmalloc_node_range() which is
never called for that area.
That went undetected until commit e4137f08816b ("mm, kasan, kmsan:
instrument copy_from/to_kernel_nofault")
The area allocated by text_area_cpu_up() is not vmalloc memory, it is
mapped directly on demand when needed by map_kernel_page(). There is
no VM flag corresponding to such usage, so just pass no flag. That way
the area will be unpoisonned and usable immediately.

Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix potential deadlock when releasing mids
All release_mid() callers seem to hold a reference of @mid so there is
no need to call kref_put(&mid->refcount, __release_mid) under
@server->mid_lock spinlock. If they don't, then an use-after-free bug
would have occurred anyways.
By getting rid of such spinlock also fixes a potential deadlock as
shown below
CPU 0 CPU 1
------------------------------------------------------------------
cifs_demultiplex_thread() cifs_debug_data_proc_show()
release_mid()
spin_lock(&server->mid_lock);
spin_lock(&cifs_tcp_ses_lock)
spin_lock(&server->mid_lock)
__release_mid()
smb2_find_smb_tcon()
spin_lock(&cifs_tcp_ses_lock) *deadlock*

Summary
In the Linux kernel, the following vulnerability has been resolved:
acct: perform last write from workqueue
In [1] it was reported that the acct(2) system call can be used to
trigger NULL deref in cases where it is set to write to a file that
triggers an internal lookup. This can e.g., happen when pointing acc(2)
to /sys/power/resume. At the point the where the write to this file
happens the calling task has already exited and called exit_fs(). A
lookup will thus trigger a NULL-deref when accessing current->fs.
Reorganize the code so that the the final write happens from the
workqueue but with the caller's credentials. This preserves the
(strange) permission model and has almost no regression risk.
This api should stop to exist though.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: Set n_channels after allocating struct cfg80211_scan_request
Make sure that n_channels is set after allocating the
struct cfg80211_registered_device::int_scan_req member. Seen with
syzkaller:
UBSAN: array-index-out-of-bounds in net/mac80211/scan.c:1208:5
index 0 is out of range for type 'struct ieee80211_channel *[] __counted_by(n_channels)' (aka 'struct ieee80211_channel *[]')
This was missed in the initial conversions because I failed to locate
the allocation likely due to the "sizeof(void *)" not matching the
"channels" array type.

Bluetooth range constitutes an adjacent network.\nAC:L - The remote peer controls both sides of the race \u2014 it chooses when to inject the L2CAP connect request relative to link setup (the exact condition named in the Fixes: commit) and can induce the concurrent connection abort by failing the security escalation its own request triggers or by repeated connect/teardown. The attempt is free to repeat until it wins.\nPR:N - L2CAP signalling commands are processed on an unauthenticated, unpaired ACL link; the hci_conn_check_link_mode() security check sits inside l2cap_connect() and executes only after the use-after-free dereference. No credentials or local account are needed.\nUI:N - Processing of an inbound ACL connection and its L2CAP connect request happens automatically in the kernel rx workqueue on any connectable device. No victim action is required.\nS:U - The corruption and its consequences are confined to the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed struct l2cap_conn is read back and its embedded pointers (conn-\u003ehcon, conn-\u003ehcon-\u003ehdev) are chased; since the object comes from a general kmalloc cache reclaimable by sprayed data, an attacker can steer those dereferences to disclose arbitrary kernel memory.\nI:H - Execution continues writing into the freed object \u2014 conn-\u003einfo_state, conn-\u003einfo_ident, conn-\u003ehcon-\u003edisc_timeout, a list_add into freed conn-\u003echan_l, and schedule_delayed_work() on a work_struct with an attacker-reclaimable function pointer \u2014 giving a write and control-flow-hijack primitive.\nA:H - The use-after-free reliably oopses the kernel in the Bluetooth rx workqueue (as KASAN reported), and mutex_lock on freed memory plus a queued timer in reclaimed slab cause panics or corruption-induced crashes."

The current implementation uses bias_pad_enable as a reference count to
manage the shared bias pad for all UTMI PHYs. However, during system
suspension with connected USB devices, multiple power-down requests for
the UTMI pad result in a mismatch in the reference count, which in turn
produces warnings such as:
[ 237.762967] WARNING: CPU: 10 PID: 1618 at tegra186_utmi_pad_power_down+0x160/0x170

[ 237.763135] pm_suspend+0x1ec/0x270
The root cause was traced back to the dynamic power-down changes
introduced in commit a30951d31b25 ("xhci: tegra: USB2 pad power controls"),
where the UTMI pad was being powered down without verifying its current
state. This unbalanced behavior led to discrepancies in the reference
count.
To rectify this issue, this patch replaces the single reference counter
with a bitmask, renamed to utmi_pad_enabled. Each bit in the mask
corresponds to one of the four USB2 PHYs, allowing us to track each pad's
enablement status individually.
With this change:
- The bias pad is powered on only when the mask is clear.
- Each UTMI pad is powered on or down based on its corresponding bit
in the mask, preventing redundant operations.
- The overall power state of the shared bias pad is maintained
correctly during suspend/resume cycles.
The mutex used to prevent race conditions during UTMI pad enable/disable
operations has been moved from the tegra186_utmi_bias_pad_power_on/off
functions to the parent functions tegra186_utmi_pad_power_on/down. This
change ensures that there are no race conditions when updating the bitmask.

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix memory leak in parse_lease_state()
The previous patch that added bounds check for create lease context
introduced a memory leak. When the bounds check fails, the function
returns NULL without freeing the previously allocated lease_ctx_info
structure.
This patch fixes the issue by adding kfree(lreq) before returning NULL
in both boundary check cases.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/huge_memory: fix dereferencing invalid pmd migration entry
When migrating a THP, concurrent access to the PMD migration entry during
a deferred split scan can lead to an invalid address access, as
illustrated below. To prevent this invalid access, it is necessary to
check the PMD migration entry and return early. In this context, there is
no need to use pmd_to_swp_entry and pfn_swap_entry_to_page to verify the
equality of the target folio. Since the PMD migration entry is locked, it
cannot be served as the target.
Mailing list discussion and explanation from Hugh Dickins: "An anon_vma
lookup points to a location which may contain the folio of interest, but
might instead contain another folio: and weeding out those other folios is
precisely what the "folio != pmd_folio((*pmd)" check (and the "risk of
replacing the wrong folio" comment a few lines above it) is for."

Since the PMD migration entry is locked, it\ncannot be served as the target.\n\nMailing list discussion and explanation from Hugh Dickins: \"An anon_vma\nlookup points to a location which may contain the folio of interest, but\nmight instead contain another folio: and weeding out those other folios is\nprecisely what the \"folio != pmd_folio((*pmd)\" check (and the \"risk of\nreplacing the wrong folio\" comment a few lines above it) is for.\"\n\nBUG: unable to handle page fault for address: ffffea60001db008\nCPU: 0 UID: 0 PID: 2199114 Comm: tee Not tainted 6.14.0+ #4 NONE\nHardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-debian-1.16.3-2 04/01/2014\nRIP: 0010:split_huge_pmd_locked+0x3b5/0x2b60\nCall Trace:\n\u003cTASK\u003e\ntry_to_migrate_one+0x28c/0x3730\nrmap_walk_anon+0x4f6/0x770\nunmap_folio+0x196/0x1f0\nsplit_huge_page_to_list_to_order+0x9f6/0x1560\ndeferred_split_scan+0xac5/0x12a0\nshrinker_debugfs_scan_write+0x376/0x470\nfull_proxy_write+0x15c/0x220\nvfs_write+0x2fc/0xcb0\nksys_write+0x146/0x250\ndo_syscall_64+0x6a/0x120\nentry_SYSCALL_64_after_hwframe+0x76/0x7e\n\nThe bug is found by syzkaller on an internal kernel, then confirmed on\nupstream."

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: m_can: m_can_class_allocate_dev(): initialize spin lock on device probe
The spin lock tx_handling_spinlock in struct m_can_classdev is not
being initialized. This leads the following spinlock bad magic
complaint from the kernel, eg. when trying to send CAN frames with
cansend from can-utils:
| BUG: spinlock bad magic on CPU#0, cansend/95

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/erofs/fileio: call erofs_onlinefolio_split() after bio_add_folio()
If bio_add_folio() fails (because it is full),
erofs_fileio_scan_folio() needs to submit the I/O request via
erofs_fileio_rq_submit() and allocate a new I/O request with an empty
`struct bio`. Then it retries the bio_add_folio() call.
However, at this point, erofs_onlinefolio_split() has already been
called which increments `folio->private`; the retry will call
erofs_onlinefolio_split() again, but there will never be a matching
erofs_onlinefolio_end() call. This leaves the folio locked forever
and all waiters will be stuck in folio_wait_bit_common().
This bug has been added by commit ce63cb62d794 ("erofs: support
unencoded inodes for fileio"), but was practically unreachable because
there was room for 256 folios in the `struct bio` - until commit
9f74ae8c9ac9 ("erofs: shorten bvecs[] for file-backed mounts") which
reduced the array capacity to 16 folios.
It was now trivial to trigger the bug by manually invoking readahead
from userspace, e.g.:
posix_fadvise(fd, 0, st.st_size, POSIX_FADV_WILLNEED);
This should be fixed by invoking erofs_onlinefolio_split() only after
bio_add_folio() has succeeded. This is safe: asynchronous completions
invoking erofs_onlinefolio_end() will not unlock the folio because
erofs_fileio_scan_folio() is still holding a reference to be released
by erofs_onlinefolio_end() at the end.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: mtk-pmic-keys - fix possible null pointer dereference
In mtk_pmic_keys_probe, the regs parameter is only set if the button is
parsed in the device tree. However, on hardware where the button is left
floating, that node will most likely be removed not to enable that
input. In that case the code will try to dereference a null pointer.
Let's use the regs struct instead as it is defined for all supported
platforms. Note that it is ok setting the key reg even if that latter is
disabled as the interrupt won't be enabled anyway.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_midi: fix MIDI Streaming descriptor lengths
While the MIDI jacks are configured correctly, and the MIDIStreaming
endpoint descriptors are filled with the correct information,
bNumEmbMIDIJack and bLength are set incorrectly in these descriptors.
This does not matter when the numbers of in and out ports are equal, but
when they differ the host will receive broken descriptors with
uninitialized stack memory leaking into the descriptor for whichever
value is smaller.
The precise meaning of "in" and "out" in the port counts is not clearly
defined and can be confusing. But elsewhere the driver consistently
uses this to match the USB meaning of IN and OUT viewed from the host,
so that "in" ports send data to the host and "out" ports receive data
from it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ndisc: extend RCU protection in ndisc_send_skb()
ndisc_send_skb() can be called without RTNL or RCU held.
Acquire rcu_read_lock() earlier, so that we can use dev_net_rcu()
and avoid a potential UAF.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sched_ext: bpf_iter_scx_dsq_new() should always initialize iterator
BPF programs may call next() and destroy() on BPF iterators even after new()
returns an error value (e.g. bpf_for_each() macro ignores error returns from
new()). bpf_iter_scx_dsq_new() could leave the iterator in an uninitialized
state after an error return causing bpf_iter_scx_dsq_next() to dereference
garbage data. Make bpf_iter_scx_dsq_new() always clear $kit->dsq so that
next() and destroy() become noops.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gpiolib: Fix crash on error in gpiochip_get_ngpios()
The gpiochip_get_ngpios() uses chip_*() macros to print messages.
However these macros rely on gpiodev to be initialised and set,
which is not the case when called via bgpio_init(). In such a case
the printing messages will crash on NULL pointer dereference.
Replace chip_*() macros by the respective dev_*() ones to avoid
such crash.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: uclogic: Add NULL check in uclogic_input_configured()
devm_kasprintf() returns NULL when memory allocation fails. Currently,
uclogic_input_configured() does not check for this case, which results
in a NULL pointer dereference.
Add NULL check after devm_kasprintf() to prevent this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: cdc-acm: Check control transfer buffer size before access
If the first fragment is shorter than struct usb_cdc_notification, we can't
calculate an expected_size. Log an error and discard the notification
instead of reading lengths from memory outside the received data, which can
lead to memory corruption when the expected_size decreases between
fragments, causing `expected_size - acm->nb_index` to wrap.
This issue has been present since the beginning of git history; however,
it only leads to memory corruption since commit ea2583529cd1
("cdc-acm: reassemble fragmented notifications").
A mitigating factor is that acm_ctrl_irq() can only execute after userspace
has opened /dev/ttyACM*; but if ModemManager is running, ModemManager will
do that automatically depending on the USB device's vendor/product IDs and
its other interfaces.

In the function rxe_create_cq, when rxe_cq_from_init fails, the function
rxe_cleanup will be called to handle the allocated resources. In fact,
some memory resources have already been freed in the function
rxe_cq_from_init. Thus, this problem will occur.
The solution is to let rxe_cleanup do all the work.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/tipc: fix slab-use-after-free Read in tipc_aead_encrypt_done
Syzbot reported a slab-use-after-free with the following call trace:

After freed the tipc_crypto tx by delete namespace, tipc_aead_encrypt_done
may still visit it in cryptd_queue_worker workqueue.
I reproduce this issue by:
ip netns add ns1
ip link add veth1 type veth peer name veth2
ip link set veth1 netns ns1
ip netns exec ns1 tipc bearer enable media eth dev veth1
ip netns exec ns1 tipc node set key this_is_a_master_key master
ip netns exec ns1 tipc bearer disable media eth dev veth1
ip netns del ns1
The key of reproduction is that, simd_aead_encrypt is interrupted, leading
to crypto_simd_usable() return false. Thus, the cryptd_queue_worker is
triggered, and the tipc_crypto tx will be visited.
tipc_disc_timeout
tipc_bearer_xmit_skb
tipc_crypto_xmit
tipc_aead_encrypt
crypto_aead_encrypt
// encrypt()
simd_aead_encrypt
// crypto_simd_usable() is false
child = &ctx->cryptd_tfm->base;
simd_aead_encrypt
crypto_aead_encrypt
// encrypt()
cryptd_aead_encrypt_enqueue
cryptd_aead_enqueue
cryptd_enqueue_request
// trigger cryptd_queue_worker
queue_work_on(smp_processor_id(), cryptd_wq, &cpu_queue->work)
Fix this by holding net reference count before encrypt.

Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio_ring: Fix data race by tagging event_triggered as racy for KCSAN
syzbot reports a data-race when accessing the event_triggered, here is the
simplified stack when the issue occurred:
==================================================================
BUG: KCSAN: data-race in virtqueue_disable_cb / virtqueue_enable_cb_delayed
write to 0xffff8881025bc452 of 1 bytes by task 3288 on cpu 0:
virtqueue_enable_cb_delayed+0x42/0x3c0 drivers/virtio/virtio_ring.c:2653
start_xmit+0x230/0x1310 drivers/net/virtio_net.c:3264
__netdev_start_xmit include/linux/netdevice.h:5151 [inline]
netdev_start_xmit include/linux/netdevice.h:5160 [inline]
xmit_one net/core/dev.c:3800 [inline]
read to 0xffff8881025bc452 of 1 bytes by interrupt on cpu 1:
virtqueue_disable_cb_split drivers/virtio/virtio_ring.c:880 [inline]
virtqueue_disable_cb+0x92/0x180 drivers/virtio/virtio_ring.c:2566
skb_xmit_done+0x5f/0x140 drivers/net/virtio_net.c:777

__handle_irq_event_percpu+0x95/0x490 kernel/irq/handle.c:158
handle_irq_event_percpu kernel/irq/handle.c:193 [inline]
value changed: 0x01 -> 0x00
==================================================================
When the data race occurs, the function virtqueue_enable_cb_delayed() sets
event_triggered to false, and virtqueue_disable_cb_split/packed() reads it
as false due to the race condition. Since event_triggered is an unreliable
hint used for optimization, this should only cause the driver temporarily
suggest that the device not send an interrupt notification when the event
index is used.
Fix this KCSAN reported data-race issue by explicitly tagging the access as
data_racy.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: prevent out-of-bounds stream writes by validating *pos
ksmbd_vfs_stream_write() did not validate whether the write offset
(*pos) was within the bounds of the existing stream data length (v_len).
If *pos was greater than or equal to v_len, this could lead to an
out-of-bounds memory write.
This patch adds a check to ensure *pos is less than v_len before
proceeding. If the condition fails, -EINVAL is returned.

Summary
In the Linux kernel, the following vulnerability has been resolved:
staging: bcm2835-camera: Initialise dev in v4l2_dev
Commit 42a2f6664e18 ("staging: vc04_services: Move global g_state to
vchiq_state") changed mmal_init to pass dev->v4l2_dev.dev to
vchiq_mmal_init, however nothing iniitialised dev->v4l2_dev, so we got
a NULL pointer dereference.
Set dev->v4l2_dev.dev during bcm2835_mmal_probe. The device pointer
could be passed into v4l2_device_register to set it, however that also
has other effects that would need additional changes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/migrate_device: don't add folio to be freed to LRU in migrate_device_finalize()
If migration succeeded, we called
folio_migrate_flags()->mem_cgroup_migrate() to migrate the memcg from the
old to the new folio. This will set memcg_data of the old folio to 0.
Similarly, if migration failed, memcg_data of the dst folio is left unset.
If we call folio_putback_lru() on such folios (memcg_data == 0), we will
add the folio to be freed to the LRU, making memcg code unhappy. Running
the hmm selftests:
# ./hmm-tests
...
# RUN hmm.hmm_device_private.migrate ...

Likely, nothing else goes wrong: putting the last folio reference will
remove the folio from the LRU again. So besides memcg complaining, adding
the folio to be freed to the LRU is just an unnecessary step.
The new flow resembles what we have in migrate_folio_move(): add the dst
to the lru, rem

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: Intel: hda: Fix UAF when reloading module
hda_generic_machine_select() appends -idisp to the tplg filename by
allocating a new string with devm_kasprintf(), then stores the string
right back into the global variable snd_soc_acpi_intel_hda_machines.
When the module is unloaded, this memory is freed, resulting in a global
variable pointing to freed memory. Reloading the module then triggers
a use-after-free:

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

No victim action is involved.\nS:U - The corrupted `qlen`/`backlog` accounting and any resulting memory corruption stay within the kernel\u0027s own security authority; this is standard local kernel privilege escalation with no VM, IOMMU, or sandbox boundary crossed.\nC:H - The double subtraction underflows the unsigned `q.qlen`, desynchronizing the qdisc tree so classes stay on parent active lists after their child qdiscs are freed, yielding a use-after-free on `struct Qdisc`/class objects that can be groomed into an arbitrary kernel-memory read.\nI:H - The same qlen-desync-to-UAF primitive gives control over reallocated heap objects and their function pointers and list heads, enabling arbitrary write and control-flow hijacking \u2014 the well-known net/sched local privilege escalation pattern.\nA:H - Even unweaponized, the underflowed `qlen` makes an empty qdisc appear to hold ~4 billion packets, causing dequeue-from-empty warnings, stalled transmit paths, and use-after-free oopses that panic the kernel."

Summary
In the Linux kernel, the following vulnerability has been resolved:
regulator: max20086: fix invalid memory access
max20086_parse_regulators_dt() calls of_regulator_match() using an
array of struct of_regulator_match allocated on the stack for the
matches argument.
of_regulator_match() calls devm_of_regulator_put_matches(), which calls
devres_alloc() to allocate a struct devm_of_regulator_matches which will
be de-allocated using devm_of_regulator_put_matches().
struct devm_of_regulator_matches is populated with the stack allocated
matches array.
If the device fails to probe, devm_of_regulator_put_matches() will be
called and will try to call of_node_put() on that stack pointer,
generating the following dmesg entries:
max20086 6-0028: Failed to read DEVICE_ID reg: -121
kobject: '\xc0$\xa5\x03' (000000002cebcb7a): is not initialized, yet
kobject_put() is being called.
Followed by a stack trace matching the call flow described above.
Switch to allocating the matches array using devm_kcalloc() to
avoid accessing the stack pointer long after it's out of scope.
This also has the advantage of allowing multiple max20086 to probe
without overriding the data stored inside the global of_regulator_match.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: fix out-of-bounds access during multi-link element defragmentation
Currently during the multi-link element defragmentation process, the
multi-link element length added to the total IEs length when calculating
the length of remaining IEs after the multi-link element in
cfg80211_defrag_mle(). This could lead to out-of-bounds access if the
multi-link element or its corresponding fragment elements are the last
elements in the IEs buffer.
To address this issue, correctly calculate the remaining IEs length by
deducting the multi-link element end offset from total IEs end offset.

This is the standard WiFi frame-injection adjacency requirement, not a routable network path.\nAC:L - The attacker fully controls the frame contents and can deterministically place a valid Basic Multi-Link element as the final IE, which makes the fragment-scan loop dereference memory exactly at `ie + ielen` on its first iteration \u2014 no race, no memory-layout luck required for the overread itself. Probe responses are accepted whenever the STA scans (foreground or PNO/sched scan), and MAC randomization or simply answering an observed probe request satisfies the DA check in `ieee80211_scan_accept_presp()`.\nPR:N - Scan-result parsing happens before any authentication or association, so an unauthenticated attacker with no credentials, no key material, and no prior relationship to the victim can reach the code. The attacker needs no account on the target and no privileges of any kind.\nUI:N - Linux/Android stations run periodic background scans and scheduled scans (PNO) automatically via wpa_supplicant/NetworkManager without any user action, and every such scan feeds received probe responses into the vulnerable path. No victim click, mount, or connection attempt is needed.\nS:U - The out-of-bounds read and any resulting fault occur entirely within the kernel\u0027s own security authority on the affected host; no VM, IOMMU, container, or sandbox boundary is crossed.\nC:H - The loop reads up to `p + 2*mle-\u003edatalen` bytes (potentially ~2.5 KB for a maximum-length probe response with the MLE placed last) beyond the end of the receive buffer into adjacent kernel heap memory \u2014 far more than a strictly bounded few-byte overread. The out-of-bounds bytes are actively interpreted as element headers and steer loop continuation and the computed allocation size, so attacker-observable behaviour depends on kernel memory the attacker must not be able to read.\nI:N - The defect is confined to the length computation of a read-only scanning loop; the erroneous bound can only over-estimate `buf_len`, and the subsequent `cfg80211_defragment_element()` call still uses the correct `ielen` and rejects overflow with `-ENOSPC`, so no out-of-bounds write or corruption of kernel state occurs.\nA:H - The walk can run kilobytes past the receive buffer into unmapped or guarded memory \u2014 KFENCE (default-enabled on Android GKI and several distro kernels), KASAN, and DEBUG_PAGEALLOC turn this into an unhandled kernel page fault/oops. The attacker can retransmit the crafted probe response indefinitely with no authentication, so repeated triggering makes a kernel panic a practical denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: synaptics - fix crash when enabling pass-through port
When enabling a pass-through port an interrupt might come before psmouse
driver binds to the pass-through port. However synaptics sub-driver
tries to access psmouse instance presumably associated with the
pass-through port to figure out if only 1 byte of response or entire
protocol packet needs to be forwarded to the pass-through port and may
crash if psmouse instance has not been attached to the port yet.
Fix the crash by introducing open() and close() methods for the port and
check if the port is open before trying to access psmouse instance.
Because psmouse calls serio_open() only after attaching psmouse instance
to serio port instance this prevents the potential crash.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: Flush gso_skb list too during ->change()
Previously, when reducing a qdisc's limit via the ->change() operation, only
the main skb queue was trimmed, potentially leaving packets in the gso_skb
list. This could result in NULL pointer dereference when we only check
sch->limit against sch->q.qlen.
This patch introduces a new helper, qdisc_dequeue_internal(), which ensures
both the gso_skb list and the main queue are properly flushed when trimming
excess packets. All relevant qdiscs (codel, fq, fq_codel, fq_pie, hhf, pie)
are updated to use this helper in their ->change() routines.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix deadlock when freeing cgroup storage
The following commit
bc235cdb423a ("bpf: Prevent deadlock from recursive bpf_task_storage_[get|delete]")
first introduced deadlock prevention for fentry/fexit programs attaching
on bpf_task_storage helpers. That commit also employed the logic in map
free path in its v6 version.
Later bpf_cgrp_storage was first introduced in
c4bcfb38a95e ("bpf: Implement cgroup storage available to non-cgroup-attached bpf progs")
which faces the same issue as bpf_task_storage, instead of its busy
counter, NULL was passed to bpf_local_storage_map_free() which opened
a window to cause deadlock:

</TASK>
Progs:
- A: SEC("fentry/cgroup_storage_ptr")
- cgid (BPF_MAP_TYPE_HASH)
Record the id of the cgroup the current task belonging
to in this hash map, using the address of the cgroup
as the map key.
- cgrpa (BPF_MAP_TYPE_CGRP_STORAGE)
If current task is a kworker, lookup the above hash
map using function parameter @owner as the key to get
its corresponding cgroup id which is then used to get
a trusted pointer to the cgroup through
bpf_cgroup_from_id(). This trusted pointer can then
be passed to bpf_cgrp_storage_get() to finally trigger
the deadlock issue.
- B: SEC("tp_btf/sys_enter")
- cgrpb (BPF_MAP_TYPE_CGRP_STORAGE)
The only purpose of this prog is to fill Prog A's
hash map by calling bpf_cgrp_storage_get() for as
many userspace tasks as possible.
Steps to reproduce:
- Run A;
- while (true) { Run B; Destroy B; }
Fix this issue by passing its busy counter to the free procedure so
it can be properly incremented before storage/smap locking.

[Analysis]
gsm_msg on the tx_ctrl_list or tx_data_list of gsm_mux
can be freed by multi threads through ioctl,which leads
to the occurrence of uaf. Protect it by gsm tx lock.

"value": "AV:L - The vulnerability is triggered entirely through local syscalls on a tty file descriptor \u2014 `ioctl(TIOCSETD, N_GSM0710)` followed by concurrent `ioctl(GSMIOC_SETCONF)` on a pty the attacker owns. No network or physical access is involved.\nAC:L - The attacker controls both sides of the race \u2014 two threads issuing `GSMIOC_SETCONF` on the same fd, which `tty_ldisc_ref_wait()`\u0027s read semaphore explicitly permits to run concurrently \u2014 and additionally controls list population by writing to the pty peer to queue `gsm_msg` nodes on demand. No condition depends on attacker-uninfluenceable state.\nPR:L - For mainline v6.0\u2013v6.5 and the never-fixed 5.18.18/5.19.2 stable branches covered by this CVE, `gsmld_open()` has no capability check at all, so any unprivileged local user with a pty reaches the bug; even on kernels carrying the later `capable(CAP_NET_ADMIN)` gate, that is a scoped, non-root-equivalent capability routinely granted to network daemons and containers (`--cap-add=NET_ADMIN`).\nUI:N - The attacker performs every step itself \u2014 allocating the pty, attaching the line discipline, feeding data, and racing the two ioctls. No victim action or cooperating process is required.\nS:U - The corruption and its consequences are confined to the kernel of the running system, a standard local privilege-escalation boundary. No hypervisor, IOMMU, or other security-authority boundary is crossed.\nC:H - The unlocked traversal reads `list.next` from a freed, attacker-reclaimable slab object, and the resulting arbitrary-free primitive converts into a use-after-free on a chosen kernel object, enabling arbitrary kernel memory disclosure.\nI:H - Concurrent `kfree()` of the same nodes double-frees them and corrupts the SLUB freelist, while a sprayed `next` pointer yields `kfree()` of an attacker-chosen address \u2014 an arbitrary-free primitive that is a well-established path to arbitrary write and control-flow hijack.\nA:H - The double-free and use-after-free reliably corrupt slab metadata, producing kernel oops or panic even in unweaponized form, as demonstrated by the KASAN slab-use-after-free report in the fix commit."

The vulnerable code is bound to the network stack and reachable from remotely originated packets, so Network is the correct and higher-severity classification.\nAC:H - The attacker fully controls and can sustain the ARP-transmit side of the race, but the other side \u2014 a `struct net` being freed via `cleanup_net()` or a device migrating namespaces \u2014 is background system activity the network attacker cannot command. Because that condition lies outside attacker control, complexity is High.\nPR:N - There is no capability check, credential check, or authentication gate anywhere on the path from packet receipt/neighbour resolution to `arp_xmit()`; ARP solicitation and reply generation happen unconditionally in softirq context. An entirely unauthenticated attacker reaches the vulnerable code.\nUI:N - The attacker\u0027s own packets cause the kernel to emit ARP and execute the vulnerable code; no victim must mount a filesystem, open a file, or take any other action.\nS:U - The use-after-free of `struct net` and the resulting corruption stay entirely within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - A use-after-free of `struct net` lets `nf_hook()` read `net-\u003enf.hooks_arp[]` and every ARP-family hook read `state-\u003enet` out of freed, potentially reallocated slab memory. Per kernel guidance a UAF gives the attacker control over the freed object\u0027s contents and thus an arbitrary kernel-memory read primitive.\nI:H - The stale `net` yields a `hook_head` pointer from freed memory, and `nf_hook_slow()` then performs an indirect call through `e-\u003ehooks[s].hook` \u2014 a direct function-pointer hijack primitive if the netns slab is reallocated with sprayed data. Hooks also write through `state-\u003enet`, corrupting reused kernel objects.\nA:H - Dereferencing a freed `struct net` and calling through a garbage `nf_hook_entries` reliably oopses or panics the kernel, and is a KASAN-reportable memory-safety violation that panics on hardened configurations. Any such kernel crash is scored High."

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: drop secpath at the same time as we currently drop dst
Xiumei reported hitting the WARN in xfrm6_tunnel_net_exit while
running tests that boil down to:
- create a pair of netns
- run a basic TCP test over ipcomp6
- delete the pair of netns
The xfrm_state found on spi_byaddr was not deleted at the time we
delete the netns, because we still have a reference on it. This
lingering reference comes from a secpath (which holds a ref on the
xfrm_state), which is still attached to an skb. This skb is not
leaked, it ends up on sk_receive_queue and then gets defer-free'd by
skb_attempt_defer_free.
The problem happens when we defer freeing an skb (push it on one CPU's
defer_list), and don't flush that list before the netns is deleted. In
that case, we still have a reference on the xfrm_state that we don't
expect at this point.
We already drop the skb's dst in the TCP receive path when it's no
longer needed, so let's also drop the secpath. At this point,
tcp_filter has already called into the LSM hooks that may require the
secpath, so it should not be needed anymore. However, in some of those
places, the MPTCP extension has just been attached to the skb, so we
cannot simply drop all extensions.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ibmvnic: Don't reference skb after sending to VIOS
Previously, after successfully flushing the xmit buffer to VIOS,
the tx_bytes stat was incremented by the length of the skb.
It is invalid to access the skb memory after sending the buffer to
the VIOS because, at any point after sending, the VIOS can trigger
an interrupt to free this memory. A race between reading skb->len
and freeing the skb is possible (especially during LPM) and will
result in use-after-free:

"value": "AV:N - `ibmvnic_xmit()` is the `ndo_start_xmit` handler executed for every frame the LPAR transmits, so an unauthenticated remote attacker reaches it simply by sending traffic that elicits kernel replies (TCP handshakes, ICMP echo, ARP) at arbitrary rate. This matches the CNA\u0027s AV:N scoring of the identical `lec_send()` skb-after-send UAF (CVE-2025-22004).\nAC:L - Every transmitted packet is an independent attempt at the window between the `H_SEND_SUB_CRQ` hcall and the `skb-\u003elen` read, and the attacker fully controls transmit volume; heavy TX load maximizes concurrent VIOS completion interrupts, which run `ibmvnic_complete_tx()` in hardirq context on another CPU. The race is hit in practice under ordinary stress workloads, requiring no condition the attacker cannot influence.\nPR:N - There is no capability, credential, or namespace check anywhere between packet ingress and `ibmvnic_xmit()`; remote traffic that provokes a kernel-generated response is sufficient. Locally, any unprivileged socket write also reaches the same path.\nUI:N - The TX path is driven entirely by network traffic or the attacker\u0027s own socket writes, with no victim action required.\nS:U - The stale read and its consequences are confined to the LPAR\u0027s own kernel memory and statistics; the VIOS/hypervisor security boundary is not crossed.\nC:L - Four bytes of freed `skbuff_head_cache` memory are accumulated into `netdev-\u003estats.tx_bytes` and `adapter-\u003etx_stats_buffers[q].bytes`, both readable by unprivileged userspace via `/proc/net/dev` and `ethtool -S`, giving a genuine leak of freed kernel slab contents. The read is strictly bounded to one 32-bit field at a fixed offset and is never used as a pointer or length, so it yields no arbitrary-read primitive.\nI:L - Kernel-maintained interface statistics consumed by userspace monitoring, accounting, and billing tooling are corrupted with values the attacker does not choose. There is no write to freed memory and no path to control-flow hijacking or arbitrary write.\nA:H - This is a use-after-free read in the hot TX path: on KASAN/debug kernels it produces the reported slab-use-after-free splat and panics under `panic_on_warn`, and if the freed skbuff slab page has been returned to the buddy allocator the load can fault (DEBUG_PAGEALLOC/KFENCE guard pages on ppc64), oopsing in softirq context. Per kernel scoring guidance any use-after-free is treated as A:H."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/tls: fix kernel panic when alloc_page failed
We cannot set frag_list to NULL pointer when alloc_page failed.
It will be used in tls_strp_check_queue_ok when the next time
tls_strp_read_sock is called.
This is because we don't reset full_len in tls_strp_flush_anchor_copy()
so the recv path will try to continue handling the partial record
on the next call but we dettached the rcvq from the frag list.
Alternative fix would be to reset full_len.
Unable to handle kernel NULL pointer dereference
at virtual address 0000000000000028

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_router: Fix use-after-free when deleting GRE net devices
The driver only offloads neighbors that are constructed on top of net
devices registered by it or their uppers (which are all Ethernet). The
device supports GRE encapsulation and decapsulation of forwarded
traffic, but the driver will not offload dummy neighbors constructed on
top of GRE net devices as they are not uppers of its net devices:
# ip link add name gre1 up type gre tos inherit local 192.0.2.1 remote 198.51.100.1
# ip neigh add 0.0.0.0 lladdr 0.0.0.0 nud noarp dev gre1
$ ip neigh show dev gre1 nud noarp
0.0.0.0 lladdr 0.0.0.0 NOARP
(Note that the neighbor is not marked with 'offload')
When the driver is reloaded and the existing configuration is replayed,
the driver does not perform the same check regarding existing neighbors
and offloads the previously added one:
# devlink dev reload pci/0000:01:00.0
$ ip neigh show dev gre1 nud noarp
0.0.0.0 lladdr 0.0.0.0 offload NOARP
If the neighbor is later deleted, the driver will ignore the
notification (given the GRE net device is not its upper) and will
therefore keep referencing freed memory, resulting in a use-after-free
[1] when the net device is deleted:
# ip neigh del 0.0.0.0 lladdr 0.0.0.0 dev gre1
# ip link del dev gre1
Fix by skipping neighbor replay if the net device for which the replay
is performed is not our upper.

Summary
In the Linux kernel, the following vulnerability has been resolved:
batman-adv: fix panic during interface removal
Reference counting is used to ensure that
batadv_hardif_neigh_node and batadv_hard_iface
are not freed before/during
batadv_v_elp_throughput_metric_update work is
finished.
But there isn't a guarantee that the hard if will
remain associated with a soft interface up until
the work is finished.
This fixes a crash triggered by reboot that looks
like this:
Call trace:
batadv_v_mesh_free+0xd0/0x4dc [batman_adv]
batadv_v_elp_throughput_metric_update+0x1c/0xa4
process_one_work+0x178/0x398
worker_thread+0x2e8/0x4d0
kthread+0xd8/0xdc
ret_from_fork+0x10/0x20
(the batadv_v_mesh_free call is misleading,
and does not actually happen)
I was able to make the issue happen more reliably
by changing hardif_neigh->bat_v.metric_work work
to be delayed work. This allowed me to track down
and confirm the fix.

soft_iface]

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: gadget: f_midi: f_midi_complete to call queue_work
When using USB MIDI, a lock is attempted to be acquired twice through a
re-entrant call to f_midi_transmit, causing a deadlock.
Fix it by using queue_work() to schedule the inner f_midi_transmit() via
a high priority work queue from the completion handler.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfs: handle failure of nfs_get_lock_context in unlock path
When memory is insufficient, the allocation of nfs_lock_context in
nfs_get_lock_context() fails and returns -ENOMEM. If we mistakenly treat
an nfs4_unlockdata structure (whose l_ctx member has been set to -ENOMEM)
as valid and proceed to execute rpc_run_task(), this will trigger a NULL
pointer dereference in nfs4_locku_prepare. For example:

Summary
In the Linux kernel, the following vulnerability has been resolved:
padata: do not leak refcount in reorder_work
A recent patch that addressed a UAF introduced a reference count leak:
the parallel_data refcount is incremented unconditionally, regardless
of the return value of queue_work(). If the work item is already queued,
the incremented refcount is never decremented.
Fix this by checking the return value of queue_work() and decrementing
the refcount when necessary.
Resolves:
Unreferenced object 0xffff9d9f421e3d80 (size 192):

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: mcast: extend RCU protection in igmp6_send()
igmp6_send() can be called without RTNL or RCU being held.
Extend RCU protection so that we can safely fetch the net pointer
and avoid a potential UAF.
Note that we no longer can use sock_alloc_send_skb() because
ipv6.igmp_sk uses GFP_KERNEL allocations which can sleep.
Instead use alloc_skb() and charge the net->ipv6.igmp_sk
socket under RCU protection.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, test_run: Fix use-after-free issue in eth_skb_pkt_type()
KMSAN reported a use-after-free issue in eth_skb_pkt_type()[1]. The
cause of the issue was that eth_skb_pkt_type() accessed skb's data
that didn't contain an Ethernet header. This occurs when
bpf_prog_test_run_xdp() passes an invalid value as the user_data
argument to bpf_test_init().
Fix this by returning an error when user_data is less than ETH_HLEN in
bpf_test_init(). Additionally, remove the check for "if (user_size >
size)" as it is unnecessary.

Per kernel scoring guidance, BPF syscall-reachable bugs are Local.\nAC:L - The attacker fully controls `data_size_in`, `batch_size`, `repeat` and the XDP program, so the out-of-range read is triggered deterministically on every invocation with no race to win. Page-pool pages are freshly allocated non-zeroed pages, and the attacker can groom which freed pages get recycled by freeing chosen content immediately beforehand.\nPR:L - `bpf_prog_test_run()` performs no capability check whatsoever \u2014 the only gate is possession of an XDP program fd, which an unprivileged process can obtain via a delegated BPF token (`bpf_token_capable()` falls back to `ns_capable(token-\u003euserns, ...)`) or a bpffs pin, since `bpf_obj_do_get()` checks only file permissions. Loading a fresh XDP program needs CAP_BPF+CAP_NET_ADMIN, but that is a container/namespace-level privilege rather than real init-namespace root, so Low is the appropriate and higher-severity choice.\nUI:N - The attacker performs the entire sequence itself via the `bpf()` syscall; no victim action, mount, or file open is needed. The XDP frames are looped straight back into the local receive path by the test-run machinery.\nS:U - The stale-memory read, the disclosed data, and the resulting malformed skb all remain within the kernel\u0027s own security authority.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: bpf: abort dispatch if device destroyed
The current HID bpf implementation assumes no output report/request will
go through it after hid_bpf_destroy_device() has been called. This leads
to a bug that unplugging certain types of HID devices causes a cleaned-
up SRCU to be accessed. The bug was previously a hidden failure until a
recent x86 percpu change [1] made it access not-present pages.
The bug will be triggered if the conditions below are met:
A) a device under the driver has some LEDs on
B) hid_ll_driver->request() is uninplemented (e.g., logitech-djreceiver)
If condition A is met, hidinput_led_worker() is always scheduled *after*
hid_bpf_destroy_device().
hid_destroy_device
` hid_bpf_destroy_device
` cleanup_srcu_struct(&hdev->bpf.srcu)
` hid_remove_device
` ...
` led_classdev_unregister
` led_trigger_set(led_cdev, NULL)
` led_set_brightness(led_cdev, LED_OFF)
` ...
` input_inject_event
` input_event_dispose
` hidinput_input_event
` schedule_work(&hid->led_work) [hidinput_led_worker]
This is fine when condition B is not met, where hidinput_led_worker()
calls hid_ll_driver->request(). This is the case for most HID drivers,
which implement it or use the generic one from usbhid. The driver itself
or an underlying driver will then abort processing the request.
Otherwise, hidinput_led_worker() tries hid_hw_output_report() and leads
to the bug.
hidinput_led_worker
` hid_hw_output_report
` dispatch_hid_bpf_output_report
` srcu_read_lock(&hdev->bpf.srcu)
` srcu_read_unlock(&hdev->bpf.srcu, idx)
The bug has existed since the introduction [2] of
dispatch_hid_bpf_output_report(). However, the same bug also exists in
dispatch_hid_bpf_raw_requests(), and I've reproduced (no visible effect
because of the lack of [1], but confirmed bpf.destroyed == 1) the bug
against the commit (i.e., the Fixes:) introducing the function. This is
because hidinput_led_worker() falls back to hid_hw_raw_request() when
hid_ll_driver->output_report() is uninplemented (e.g., logitech-
djreceiver).
hidinput_led_worker
` hid_hw_output_report: -ENOSYS
` hid_hw_raw_request
` dispatch_hid_bpf_raw_requests
` srcu_read_lock(&hdev->bpf.srcu)
` srcu_read_unlock(&hdev->bpf.srcu, idx)
Fix the issue by returning early in the two mentioned functions if
hid_bpf has been marked as destroyed. Though
dispatch_hid_bpf_device_event() handles input events, and there is no
evidence that it may be called after the destruction, the same check, as
a safety net, is also added to it to maintain the consistency among all
dispatch functions.
The impact of the bug on other architectures is unclear. Even if it acts
as a hidden failure, this is still dangerous because it corrupts
whatever is on the address calculated by SRCU. Thus, CC'ing the stable
list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: SVM: Forcibly leave SMM mode on SHUTDOWN interception
Previously, commit ed129ec9057f ("KVM: x86: forcibly leave nested mode
on vCPU reset") addressed an issue where a triple fault occurring in
nested mode could lead to use-after-free scenarios. However, the commit
did not handle the analogous situation for System Management Mode (SMM).
This omission results in triggering a WARN when KVM forces a vCPU INIT
after SHUTDOWN interception while the vCPU is in SMM. This situation was
reprodused using Syzkaller by:
1) Creating a KVM VM and vCPU
2) Sending a KVM_SMI ioctl to explicitly enter SMM
3) Executing invalid instructions causing consecutive exceptions and
eventually a triple fault
The issue manifests as follows:

Architecturally, INIT is blocked when the CPU is in SMM, hence KVM's WARN()
in kvm_vcpu_reset() to guard against KVM bugs, e.g. to detect improper
emulation of INIT. SHUTDOWN on SVM is a weird edge case where KVM needs to
do _something_ sane with the VMCB, since it's technically undefined, and
INIT is the least awful choice given KVM's ABI.
So, double down on stuffing INIT on SHUTDOWN, and force the vCPU out of
SMM to avoid any weirdness (and the WARN).

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: bcm: add locking for bcm_op runtime updates
The CAN broadcast manager (CAN BCM) can send a sequence of CAN frames via
hrtimer. The content and also the length of the sequence can be changed
resp reduced at runtime where the 'currframe' counter is then set to zero.
Although this appeared to be a safe operation the updates of 'currframe'
can be triggered from user space and hrtimer context in bcm_can_tx().
Anderson Nascimento created a proof of concept that triggered a KASAN
slab-out-of-bounds read access which can be prevented with a spin_lock_bh.
At the rework of bcm_can_tx() the 'count' variable has been moved into
the protected section as this variable can be modified from both contexts
too.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: cadence: macb: Fix a possible deadlock in macb_halt_tx.
There is a situation where after THALT is set high, TGO stays high as
well. Because jiffies are never updated, as we are in a context with
interrupts disabled, we never exit that loop and have a deadlock.
That deadlock was noticed on a sama5d4 device that stayed locked for days.
Use retries instead of jiffies so that the timeout really works and we do
not have a deadlock anymore.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/page_alloc: fix race condition in unaccepted memory handling
The page allocator tracks the number of zones that have unaccepted memory
using static_branch_enc/dec() and uses that static branch in hot paths to
determine if it needs to deal with unaccepted memory.
Borislav and Thomas pointed out that the tracking is racy: operations on
static_branch are not serialized against adding/removing unaccepted pages
to/from the zone.
Sanity checks inside static_branch machinery detects it:
WARNING: CPU: 0 PID: 10 at kernel/jump_label.c:276 __static_key_slow_dec_cpuslocked+0x8e/0xa0
The comment around the WARN() explains the problem:
/*
* Warn about the '-1' case though; since that means a
* decrement is concurrent with a first (0->1) increment. IOW
* people are trying to disable something that wasn't yet fully
* enabled. This suggests an ordering problem on the user side.
*/
The effect of this static_branch optimization is only visible on
microbenchmark.
Instead of adding more complexity around it, remove it altogether.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Reject Hyper-V's SEND_IPI hypercalls if local APIC isn't in-kernel
Advertise support for Hyper-V's SEND_IPI and SEND_IPI_EX hypercalls if and
only if the local API is emulated/virtualized by KVM, and explicitly reject
said hypercalls if the local APIC is emulated in userspace, i.e. don't rely
on userspace to opt-in to KVM_CAP_HYPERV_ENFORCE_CPUID.
Rejecting SEND_IPI and SEND_IPI_EX fixes a NULL-pointer dereference if
Hyper-V enlightenments are exposed to the guest without an in-kernel local
APIC:

Note, checking the sending vCPU is sufficient, as the per-VM irqchip_mode
can't be modified after vCPUs are created, i.e. if one vCPU has an
in-kernel local APIC, then all vCPUs have an in-kernel local APIC.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tee: optee: Fix supplicant wait loop
OP-TEE supplicant is a user-space daemon and it's possible for it
be hung or crashed or killed in the middle of processing an OP-TEE
RPC call. It becomes more complicated when there is incorrect shutdown
ordering of the supplicant process vs the OP-TEE client application which
can eventually lead to system hang-up waiting for the closure of the
client application.
Allow the client process waiting in kernel for supplicant response to
be killed rather than indefinitely waiting in an unkillable state. Also,
a normal uninterruptible wait should not have resulted in the hung-task
watchdog getting triggered, but the endless loop would.
This fixes issues observed during system reboot/shutdown when supplicant
got hung for some reason or gets crashed/killed which lead to client
getting hung in an unkillable state. It in turn lead to system being in
hung up state requiring hard power off/on to recover.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: cls_api: fix error handling causing NULL dereference
tcf_exts_miss_cookie_base_alloc() calls xa_alloc_cyclic() which can
return 1 if the allocation succeeded after wrapping. This was treated as
an error, with value 1 returned to caller tcf_exts_init_ex() which sets
exts->actions to NULL and returns 1 to caller fl_change().
fl_change() treats err == 1 as success, calling tcf_exts_validate_ex()
which calls tcf_action_init() with exts->actions as argument, where it
is dereferenced.
Example trace:
BUG: kernel NULL pointer dereference, address: 0000000000000000
CPU: 114 PID: 16151 Comm: handler114 Kdump: loaded Not tainted 5.14.0-503.16.1.el9_5.x86_64 #1

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: hub: Ignore non-compliant devices with too many configs or interfaces
Robert Morris created a test program which can cause
usb_hub_to_struct_hub() to dereference a NULL or inappropriate
pointer:
Oops: general protection fault, probably for non-canonical address
0xcccccccccccccccc: 0000 [#1] SMP DEBUG_PAGEALLOC PTI
CPU: 7 UID: 0 PID: 117 Comm: kworker/7:1 Not tainted 6.13.0-rc3-00017-gf44d154d6e3d #14
Hardware name: FreeBSD BHYVE/BHYVE, BIOS 14.0 10/17/2021
Workqueue: usb_hub_wq hub_event
RIP: 0010:usb_hub_adjust_deviceremovable+0x78/0x110

The cause of this error is that the device has two interfaces, and the
hub driver binds to interface 1 instead of interface 0, which is where
usb_hub_to_struct_hub() looks.
We can prevent the problem from occurring by refusing to accept hub
devices that violate the USB spec by having more than one
configuration or interface.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: Fix UAF in __close_file_table_ids
A use-after-free is possible if one thread destroys the file
via __ksmbd_close_fd while another thread holds a reference to
it. The existing checks on fp->refcount are not sufficient to
prevent this.
The fix takes ft->lock around the section which removes the
file from the file table. This prevents two threads acquiring the
same file pointer via __close_file_table_ids, as well as the other
functions which retrieve a file from the IDR and which already use
this same lock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sockmap, vsock: For connectible sockets allow only connected
sockmap expects all vsocks to have a transport assigned, which is expressed
in vsock_proto::psock_update_sk_prot(). However, there is an edge case
where an unconnected (connectible) socket may lose its previously assigned
transport. This is handled with a NULL check in the vsock/BPF recv path.
Another design detail is that listening vsocks are not supposed to have any
transport assigned at all. Which implies they are not supported by the
sockmap. But this is complicated by the fact that a socket, before
switching to TCP_LISTEN, may have had some transport assigned during a
failed connect() attempt. Hence, we may end up with a listening vsock in a
sockmap, which blows up quickly:
KASAN: null-ptr-deref in range [0x0000000000000120-0x0000000000000127]
CPU: 7 UID: 0 PID: 56 Comm: kworker/7:0 Not tainted 6.14.0-rc1+
Workqueue: vsock-loopback vsock_loopback_work
RIP: 0010:vsock_read_skb+0x4b/0x90
Call Trace:
sk_psock_verdict_data_ready+0xa4/0x2e0
virtio_transport_recv_pkt+0x1ca8/0x2acc
vsock_loopback_work+0x27d/0x3f0

kthread+0x35a/0x700
ret_from_fork+0x2d/0x70
ret_from_fork_asm+0x1a/0x30
For connectible sockets, instead of relying solely on the state of
vsk->transport, tell sockmap to only allow those representing established
connections. This aligns with the behaviour for AF_INET and AF_UNIX.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix panic in failed foilio allocation
commit 7e119cff9d0a ("ocfs2: convert w_pages to w_folios") and commit
9a5e08652dc4b ("ocfs2: use an array of folios instead of an array of
pages") save -ENOMEM in the folio array upon allocation failure and call
the folio array free code.
The folio array free code expects either valid folio pointers or NULL.
Finding the -ENOMEM will result in a panic. Fix by NULLing the error
folio entry.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: bsg: Set bsg_queue to NULL after removal
Currently, this does not cause any issues, but I believe it is necessary to
set bsg_queue to NULL after removing it to prevent potential use-after-free
(UAF) access.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ipv6: fix dst ref loops in rpl, seg6 and ioam6 lwtunnels
Some lwtunnels have a dst cache for post-transformation dst.
If the packet destination did not change we may end up recording
a reference to the lwtunnel in its own cache, and the lwtunnel
state will never be freed.
Discovered by the ioam6.sh test, kmemleak was recently fixed
to catch per-cpu memory leaks. I'm not sure if rpl and seg6
can actually hit this, but in principle I don't see why not.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xenbus: Use kref to track req lifetime
Marek reported seeing a NULL pointer fault in the xenbus_thread
callstack:
BUG: kernel NULL pointer dereference, address: 0000000000000000
RIP: e030:__wake_up_common+0x4c/0x180
Call Trace:
<TASK>
__wake_up_common_lock+0x82/0xd0
process_msg+0x18e/0x2f0
xenbus_thread+0x165/0x1c0
process_msg+0x18e is req->cb(req). req->cb is set to xs_wake_up(), a
thin wrapper around wake_up(), or xenbus_dev_queue_reply(). It seems
like it was xs_wake_up() in this case.
It seems like req may have woken up the xs_wait_for_reply(), which
kfree()ed the req. When xenbus_thread resumes, it faults on the zero-ed
data.
Linux Device Drivers 2nd edition states:
"Normally, a wake_up call can cause an immediate reschedule to happen,
meaning that other processes might run before wake_up returns."
... which would match the behaviour observed.
Change to keeping two krefs on each request. One for the caller, and
one for xenbus_thread. Each will kref_put() when finished, and the last
will free it.
This use of kref matches the description in
Documentation/core-api/kref.rst

{
"lang": "en",
"value": "AV:L - The race is between the in-guest `xenbus_thread` and a local task blocked in `read_reply()`; it is driven by local writes to the `/dev/xen/xenbus` (or `/proc/xen/xenbus`) character device or by local sysfs/kernel-initiated xenstore requests. No network protocol handling is involved, so this requires local access to the Xen guest or dom0.\nAC:L - The attacker controls both sides of the race \u2014 their own thread is the waiter that performs the `kfree()`, and they issue the requests that cause `xenbus_thread` to call `wake_up()` \u2014 so they can retry unbounded, pin the racing threads to separate CPUs, and add scheduler load to widen the window. The bug is known to fire spontaneously during ordinary operation, confirming no attacker-uncontrollable precondition.\nPR:L - There is no `capable()` or credential check anywhere on the vulnerable path \u2014 unlike `xenbus_dev_backend.c` which gates on `CAP_SYS_ADMIN`, `xen_xenbus_fops` has none, so any user granted the xenbus device node can drive `XS_WATCH`/`XS_UNWATCH` into `xs_talkv()`; the world-readable `/sys/hypervisor/uuid` (mode 0444) also reaches `xenbus_read()` \u2192 `xs_talkv()`. A basic unprivileged local account suffices in realistic Xen deployments.\nUI:N - The attacker triggers the race entirely from their own thread pair by issuing xenstore requests and waiting for replies; no victim action, mount, or file open is required.\nS:U - The freed `xb_req_data` and the resulting corruption both live in the same kernel\u0027s slab, so the impact stays within the compromised guest\u0027s (or dom0\u0027s) security authority. No hypervisor, IOMMU, or VM boundary is crossed by the memory corruption itself.\nC:H - The use-after-free lets the attacker reallocate the freed `xb_req_data` with sprayed content that `__wake_up_common` then reads as a `wait_queue_entry` list, and the corrupted-object primitive is readily leveraged into arbitrary kernel memory disclosure. The object comes from a generic `kmalloc-128`/`kmalloc-192` cache shared with attacker-controllable allocations.\nI:H - `__wake_up_common` performs an indirect call `curr-\u003efunc(curr, ...)` through a pointer read from the freed object, and `spin_unlock_irqrestore()` writes into the freed slot after reallocation \u2014 giving both control-flow hijack and a targeted write primitive, i.e. full kernel privilege escalation potential.\nA:H - The reported real-world symptom is a kernel NULL pointer dereference and oops in `__wake_up_common` from `xenbus_thread`, killing the xenstore transport thread and panicking the kernel. Any unsuccessful exploitation attempt likewise crashes the guest or dom0."

"value": "AV:L - The decisive side of the race \u2014 `dev_net_set()` during netdevice namespace migration or `default_device_exit_batch()` on netns teardown, followed by freeing the `struct net` \u2014 is driven only by local syscalls (`unshare(CLONE_NEWNET|CLONE_NEWUSER)`, RTM_NEWLINK/RTM_SETLINK). A purely remote or adjacent peer can generate ARP/NDISC traffic to reach `__neigh_notify()` but cannot cause the namespace pointer to go stale.\nAC:L - The attacker controls both sides: they spin a loop creating/destroying network namespaces with veth devices while concurrently driving neighbour add/update/GC notifications on other CPUs, so the race is created rather than waited for. Per race-condition guidance, attacker-created races are Low even though the window between the `dev_net()` load and the `net-\u003ertnl` dereference is narrow.\nPR:L - `unshare -Urn` grants namespace-relative CAP_NET_ADMIN (`ns_capable(net-\u003euser_ns, CAP_NET_ADMIN)`), letting an ordinary unprivileged user create netns, create and move veth pairs, and trigger the teardown path; no real root is needed. Neighbour-table activity that reaches `__neigh_notify()` is likewise available to any unprivileged process.\nUI:N - The attacker triggers both the namespace teardown and the neighbour notifications entirely from their own processes. No victim action, mount, or file open is involved.\nS:U - The use-after-free and its consequences are confined to kernel memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed. This is standard in-kernel corruption leading to local privilege escalation.\nC:H - The freed `struct net` is a reclaimable `net_cachep` slab object, and `net-\u003ertnl` is subsequently consumed as a `struct sock *` by `netlink_set_err()`/`nlmsg_notify()`, which read `sk-\u003esk_protocol` and `sock_net(sk)` and walk netlink tables from it. Heap-spraying the freed object turns this into an attacker-directed kernel read primitive.\nI:H - With the freed `struct net` reclaimed under attacker control, `netlink_set_err()` writes through the forged `sk` pointer (`sk-\u003esk_err = err`, list/waitqueue manipulation), giving a controlled kernel write usable for control-flow hijacking. Per guidance, use-after-free is scored High for integrity.\nA:H - Even without successful reclaim, dereferencing the freed `struct net` and the dangling `net-\u003ertnl` socket causes a kernel oops or panic in `nlmsg_notify()`/`netlink_set_err()`. The trigger loop can be repeated indefinitely by an unprivileged user."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipvs: fix uninit-value for saddr in do_output_route4
syzbot reports for uninit-value for the saddr argument [1].
commit 4754957f04f5 ("ipvs: do not use random local source address for
tunnels") already implies that the input value of saddr
should be ignored but the code is still reading it which can prevent
to connect the route. Fix it by changing the argument to ret_saddr.
[1]

Summary
In the Linux kernel, the following vulnerability has been resolved:
module: ensure that kobject_put() is safe for module type kobjects
In 'lookup_or_create_module_kobject()', an internal kobject is created
using 'module_ktype'. So call to 'kobject_put()' on error handling
path causes an attempt to use an uninitialized completion pointer in
'module_kobject_release()'. In this scenario, we just want to release
kobject without an extra synchronization required for a regular module
unloading process, so adding an extra check whether 'complete()' is
actually required makes 'kobject_put()' safe.

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: etas_es58x: fix potential NULL pointer dereference on udev->serial
The driver assumed that es58x_dev->udev->serial could never be NULL.
While this is true on commercially available devices, an attacker
could spoof the device identity providing a NULL USB serial number.
That would trigger a NULL pointer dereference.
Add a check on es58x_dev->udev->serial before accessing it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: avoid holding freeze_mutex during mmap operation
We use map->freeze_mutex to prevent races between map_freeze() and
memory mapping BPF map contents with writable permissions. The way we
naively do this means we'll hold freeze_mutex for entire duration of all
the mm and VMA manipulations, which is completely unnecessary. This can
potentially also lead to deadlocks, as reported by syzbot in [0].
So, instead, hold freeze_mutex only during writeability checks, bump
(proactively) "write active" count for the map, unlock the mutex and
proceed with mmap logic. And only if something went wrong during mmap
logic, then undo that "write active" counter increment.

Summary
In the Linux kernel, the following vulnerability has been resolved:
md/md-bitmap: Synchronize bitmap_get_stats() with bitmap lifetime
After commit ec6bb299c7c3 ("md/md-bitmap: add 'sync_size' into struct
md_bitmap_stats"), following panic is reported:
Oops: general protection fault, probably for non-canonical address
RIP: 0010:bitmap_get_stats+0x2b/0xa0
Call Trace:
<TASK>
md_seq_show+0x2d2/0x5b0
seq_read_iter+0x2b9/0x470
seq_read+0x12f/0x180
proc_reg_read+0x57/0xb0
vfs_read+0xf6/0x380
ksys_read+0x6c/0xf0
do_syscall_64+0x82/0x170
entry_SYSCALL_64_after_hwframe+0x76/0x7e
Root cause is that bitmap_get_stats() can be called at anytime if mddev
is still there, even if bitmap is destroyed, or not fully initialized.
Deferenceing bitmap in this case can crash the kernel. Meanwhile, the
above commit start to deferencing bitmap->storage, make the problem
easier to trigger.
Fix the problem by protecting bitmap_get_stats() with bitmap_info.mutex.

The lifetime-race variant is likewise attacker-driven, since the attacker can spin on /proc/mdstat reads at arbitrary rate to hit the resize/load/destroy window.\nPR:L - /proc/mdstat is world-readable (S_IRUGO) with no capability check in md_seq_open() or md_seq_show(), so only an ordinary unprivileged local account is needed. The vulnerable array configuration is an environmental precondition set by the administrator or mdmon, not a privilege the attacker must hold.\nUI:N - The attacker triggers the bug entirely on its own by reading /proc/mdstat; no victim action, mount, or file open by another user is required. Existing md arrays are enumerated automatically by the seq_file iterator.\nS:U - The corruption and its consequences stay within the kernel\u0027s own security authority on the same host, with no crossing of a VM, IOMMU, or sandbox boundary. This is a standard in-kernel memory-safety defect.\nC:H - The unsynchronized access dereferences bitmap storage that concurrent __bitmap_resize()/bitmap_load()/bitmap_destroy() may have freed, kmapping a stale struct page and passing a dangling struct file to seq_file_path(), whose result is printed into the attacker-read /proc/mdstat. A groomed reallocation of the freed object turns this into a kernel-memory read primitive with the data disclosed to userspace.\nI:H - This is a use-after-free/lifetime defect on the bitmap and its storage, and a stale sb_page pointer controlled via heap reallocation is handed to kmap_local_page(), letting attacker-influenced kernel state drive subsequent memory accesses. Consistent with kernel UAF scoring, the corrupted-object dereference is treated as exploitable for control over kernel data.\nA:H - The reported and reproducible outcome is a general protection fault on a non-canonical address in bitmap_get_stats(), i.e. a kernel oops (panic with panic_on_oops), triggerable at will by any local user. Worse, the fault occurs while spin_lock(\u0026mddev-\u003elock) is held, leaking the spinlock and deadlocking all further md activity on that array."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix null check of pipe_ctx->plane_state for update_dchubp_dpp
Similar to commit 6a057072ddd1 ("drm/amd/display: Fix null check for
pipe_ctx->plane_state in dcn20_program_pipe") that addresses a null
pointer dereference on dcn20_update_dchubp_dpp. This is the same
function hooked for update_dchubp_dpp in dcn401, with the same issue.
Fix possible null pointer deference on dcn401_program_pipe too.
(cherry picked from commit d8d47f739752227957d8efc0cb894761bfe1d879)

Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: light: opt3001: fix deadlock due to concurrent flag access
The threaded IRQ function in this driver is reading the flag twice: once to
lock a mutex and once to unlock it. Even though the code setting the flag
is designed to prevent it, there are subtle cases where the flag could be
true at the mutex_lock stage and false at the mutex_unlock stage. This
results in the mutex not being unlocked, resulting in a deadlock.
Fix it by making the opt3001_irq() code generally more robust, reading the
flag into a variable and using the variable value at both stages.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvmet-tcp: don't restore null sk_state_change
queue->state_change is set as part of nvmet_tcp_set_queue_sock(), but if
the TCP connection isn't established when nvmet_tcp_set_queue_sock() is
called then queue->state_change isn't set and sock->sk->sk_state_change
isn't replaced.
As such we don't need to restore sock->sk->sk_state_change if
queue->state_change is NULL.
This avoids NULL pointer dereferences such as this:

Summary
In the Linux kernel, the following vulnerability has been resolved:
memblock: Accept allocated memory before use in memblock_double_array()
When increasing the array size in memblock_double_array() and the slab
is not yet available, a call to memblock_find_in_range() is used to
reserve/allocate memory. However, the range returned may not have been
accepted, which can result in a crash when booting an SNP guest:

Mitigate this by calling accept_memory() on the memory range returned
before the slab is available.
Prior to v6.12, the accept_memory() interface used a 'start' and 'end'
parameter instead of 'start' and 'size', therefore the accept_memory()
call must be adjusted to specify 'start + size' for 'end' when applying
to kernels prior to v6.12.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: pcm: Fix race of buffer access at PCM OSS layer
The PCM OSS layer tries to clear the buffer with the silence data at
initialization (or reconfiguration) of a stream with the explicit call
of snd_pcm_format_set_silence() with runtime->dma_area. But this may
lead to a UAF because the accessed runtime->dma_area might be freed
concurrently, as it's performed outside the PCM ops.
For avoiding it, move the code into the PCM core and perform it inside
the buffer access lock, so that it won't be changed during the
operation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: bcm: add missing rcu read protection for procfs content
When the procfs content is generated for a bcm_op which is in the process
to be removed the procfs output might show unreliable data (UAF).
As the removal of bcm_op's is already implemented with rcu handling this
patch adds the missing rcu_read_lock() and makes sure the list entries
are properly removed under rcu protection.

Summary
In the Linux kernel, the following vulnerability has been resolved:
libnvdimm/labels: Fix divide error in nd_label_data_init()
If a faulty CXL memory device returns a broken zero LSA size in its
memory device information (Identify Memory Device (Opcode 4000h), CXL
spec. 3.1, 8.2.9.9.1.1), a divide error occurs in the libnvdimm
driver:
Oops: divide error: 0000 [#1] PREEMPT SMP NOPTI
RIP: 0010:nd_label_data_init+0x10e/0x800 [libnvdimm]
Code and flow:
1) CXL Command 4000h returns LSA size = 0
2) config_size is assigned to zero LSA size (CXL pmem driver):
drivers/cxl/pmem.c: .config_size = mds->lsa_size,
3) max_xfer is set to zero (nvdimm driver):
drivers/nvdimm/label.c: max_xfer = min_t(size_t, ndd->nsarea.max_xfer, config_size);
4) A subsequent DIV_ROUND_UP() causes a division by zero:
drivers/nvdimm/label.c: /* Make our initial read size a multiple of max_xfer size */
drivers/nvdimm/label.c: read_size = min(DIV_ROUND_UP(read_size, max_xfer) * max_xfer,
drivers/nvdimm/label.c- config_size);
Fix this by checking the config size parameter by extending an
existing check.

If drop_monitor is built as a kernel module, syzkaller may have time
to send a netlink NET_DM_CMD_START message during the module loading.
This will call the net_dm_monitor_start() function that uses
a spinlock that has not yet been initialized.
To fix this, let's place resource initialization above the registration
of a generic netlink family.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: disable napi on driver removal
A warning on driver removal started occurring after commit 9dd05df8403b
("net: warn if NAPI instance wasn't shut down"). Disable tx napi before
deleting it in mt76_dma_cleanup().
WARNING: CPU: 4 PID: 18828 at net/core/dev.c:7288 __netif_napi_del_locked+0xf0/0x100
CPU: 4 UID: 0 PID: 18828 Comm: modprobe Not tainted 6.15.0-rc4 #4 PREEMPT(lazy)
Hardware name: ASUS System Product Name/PRIME X670E-PRO WIFI, BIOS 3035 09/05/2024
RIP: 0010:__netif_napi_del_locked+0xf0/0x100
Call Trace:

Tested with mt7921e but the same pattern can be actually applied to other
mt76 drivers calling mt76_dma_cleanup() during removal. Tx napi is enabled
in their *_dma_init() functions and only toggled off and on again inside
their suspend/resume/reset paths. So it should be okay to disable tx
napi in such a generic way.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ax25: Fix refcount leak caused by setting SO_BINDTODEVICE sockopt
If an AX25 device is bound to a socket by setting the SO_BINDTODEVICE
socket option, a refcount leak will occur in ax25_release().
Commit 9fd75b66b8f6 ("ax25: Fix refcount leaks caused by ax25_cb_del()")
added decrement of device refcounts in ax25_release(). In order for that
to work correctly the refcounts must already be incremented when the
device is bound to the socket. An AX25 device can be bound to a socket
by either calling ax25_bind() or setting SO_BINDTODEVICE socket option.
In both cases the refcounts should be incremented, but in fact it is done
only in ax25_bind().
This bug leads to the following issue reported by Syzkaller:
================================================================
refcount_t: decrement hit 0; leaking memory.

Fix the implementation of ax25_setsockopt() by adding increment of
refcounts for the new device bound, and decrement of refcounts for
the old unbound device.

No network packet or remote peer input is involved in reaching the faulty refcount path.\nAC:L - The underflow is fully deterministic \u2014 every socket bound via SO_BINDTODEVICE and then closed drops two references it never took, with no race to win and no memory layout the attacker cannot influence. The cycle can be repeated arbitrarily to drive `ax25_dev-\u003erefcount` to zero on demand and then groom the freed slab.\nPR:L - Creating an AF_AX25 SOCK_DGRAM socket and setting SO_BINDTODEVICE require no capabilities at all \u2014 the only `capable(CAP_NET_RAW)` check in `ax25_create()` guards SOCK_RAW. On any system with AX.25 already configured (packet-radio node, APRS igate, embedded radio gateway), an ordinary unprivileged user can trigger it.\nUI:N - The attacker performs the entire sequence in their own process; no victim action, mount, or file open is needed. Closing the socket is what fires the erroneous `netdev_put()`/`ax25_dev_put()`.\nS:U - The corrupted refcounts and freed objects (`struct ax25_dev`, `struct net_device`) live in the kernel, and exploitation yields kernel-level compromise within the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The premature `kfree_rcu()` of `ax25_dev` leaves `dev-\u003eax25_ptr` dangling and read by `ax25_rcv()`, `ax25_out.c`, and `ax25_ip_xmit()`, so reallocated slab contents are read back as `values[]`, `forward`, and `sysheader`. A use-after-free of this shape gives the attacker a path to disclose arbitrary kernel memory.\nI:H - After the underflow frees `ax25_dev`, the attacker can spray the slab and control `struct net_device *forward` (used as a transmit target by `ax25_fwd_dev()`), `sysheader`, and the DAMA `timer_list`, yielding write and control-flow-hijack primitives. The parallel `net_device` refcount underflow lets `unregister_netdevice()` free a netdev still in use.\nA:H - The immediate observable is a `refcount_warn_saturate` WARN followed by dereference of freed memory in the AX.25 receive and transmit paths, i.e. kernel oops/panic. Any unprivileged user can repeat the trigger to reliably crash the machine."

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: clear acl_access/acl_default after releasing them
If getting acl_default fails, acl_access and acl_default will be released
simultaneously. However, acl_access will still retain a pointer pointing
to the released posix_acl, which will trigger a WARNING in
nfs3svc_release_getacl like this:
------------[ cut here ]------------

Summary
In the Linux kernel, the following vulnerability has been resolved:
openvswitch: Fix unsafe attribute parsing in output_userspace()
This patch replaces the manual Netlink attribute iteration in
output_userspace() with nla_for_each_nested(), which ensures that only
well-formed attributes are processed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
workqueue: Put the pwq after detaching the rescuer from the pool
The commit 68f83057b913("workqueue: Reap workers via kthread_stop() and
remove detach_completion") adds code to reap the normal workers but
mistakenly does not handle the rescuer and also removes the code waiting
for the rescuer in put_unbound_pool(), which caused a use-after-free bug
reported by Cheung Wall.
To avoid the use-after-free bug, the pool’s reference must be held until
the detachment is complete. Therefore, move the code that puts the pwq
after detaching the rescuer from the pool.

No capability check guards the rescuer path.\nUI:N - The rescuer is summoned automatically by the workqueue watchdog timer under memory pressure; no action by any other user or administrator-victim is needed to complete the attack.\nS:U - The freed object and the corruption both live in kernel heap memory within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - The freed `struct worker_pool` is read after free (`pool-\u003eflags`, `worker-\u003enode` list pointers) and comes from a generic kmalloc cache, so a reallocated victim object leaks its contents through the rescuer\u0027s list manipulation, giving a path to arbitrary kernel memory disclosure.\nI:H - `detach_worker()`\u0027s `list_del(\u0026worker-\u003enode)` performs a write-after-free of kernel pointers at the fixed offset of `pool-\u003eworkers` into the freed slab object, which after heap spraying yields a controlled-offset write primitive usable for control-flow hijack and privilege escalation.\nA:H - Use-after-free on the worker pool corrupts the attached-workers list and typically produces an immediate oops/panic (KASAN reported it as a UAF), permanently wedging or crashing the kernel."

Summary
In the Linux kernel, the following vulnerability has been resolved:
dma-buf: insert memory barrier before updating num_fences
smp_store_mb() inserts memory barrier after storing operation.
It is different with what the comment is originally aiming so Null
pointer dereference can be happened if memory update is reordered.

No network or remote peer input reaches dma_resv_add_fence().\nAC:L - The attacker controls both sides of the race \u2014 one thread adds fences via DMA_BUF_IOCTL_IMPORT_SYNC_FILE while another iterates them locklessly via EXPORT_SYNC_FILE/SYNC \u2014 pinning threads to separate CPUs and looping indefinitely, and can groom the slab so the uninitialized slot holds a chosen value. The equivalent race was already demonstrated by the unprivileged igt/gem_busy/close-race testcase producing a GPF with slab poison, and affected weakly-ordered arm64 hardware is mainstream, not a rare configuration.\nPR:L - Only an unprivileged local user is needed: a dma-buf fd from /dev/dma_heap (accessible to every Android app) or a DRM render node (world/render-group accessible on desktops and containers with GPU passthrough), and all the relevant DRM ioctls are marked DRM_RENDER_ALLOW.\nUI:N - The attacker\u0027s own two threads perform both the fence addition and the lockless iteration on its own file descriptors. No victim action of any kind is required.\nS:U - The corruption occurs in kernel memory within the same security authority as the attacking process; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - The reader dereferences an uninitialized/stale slab slot as a struct dma_fence *, giving reads at attacker-groomable addresses, and the bogus fence can be wrapped into a sync_file fd whose SYNC_IOC_FILE_INFO returns kernel-memory-derived strings and fields to userspace. Stale slots may also hold already-released fence pointers, a classic use-after-free read.\nI:H - kref_get_unless_zero() on the wild pointer performs an atomic increment at an attacker-influenced kernel address, and the subsequent dma_fence_is_signaled() makes an indirect call through fence-\u003eops-\u003esignaled \u2014 an attacker-controlled function pointer \u2014 providing both a write primitive and control-flow hijack potential.\nA:H - The documented manifestations are a NULL pointer dereference (per the commit message) and a general protection fault from dereferencing garbage heap data (per the Fixes: commit\u0027s oops log), both of which panic or oops the kernel.

This problem is similar to the problem that the
commit 1d6a9e7449e2 ("RDMA/core: Fix use-after-free when rename device name")
fixes.
The root cause is: the function ib_device_rename() renames the name with
lock. But in the function kobject_uevent(), this name is accessed without
lock protection at the same time.
The solution is to add the lock protection when this name is accessed in
the function kobject_uevent().

No remote peer data reaches the vulnerable code.\nAC:L - The attacker controls both sides of the race, looping RDMA_NLDEV_CMD_NEWLINK in one thread and RDMA_NLDEV_CMD_SET (rename) in another; `enable_device_and_get()` marks the device DEVICE_REGISTERED and drops to refcount 2 before the unprotected `kobject_uevent()`, leaving a reliably hittable window that syzkaller reproduced.\nPR:L - The gate is `netlink_capable(skb, CAP_NET_ADMIN)`, which checks init_user_ns and so is not obtainable via `unshare -Urn`, but CAP_NET_ADMIN in the initial user namespace is routinely delegated to non-root, container-confined workloads (Docker/K8s do not enable user namespaces by default, and RDMA/SR-IOV network plugins commonly run with `--cap-add=NET_ADMIN`). Scored as a low-privileged principal rather than real host root.\nUI:N - The attacker triggers both the device registration and the concurrent rename entirely on its own via netlink; no victim action is involved.\nS:U - The use-after-free is in kernel slab memory and its impact stays within the kernel\u0027s security authority; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The freed `kobj-\u003ename` slab object is `strlen`\u0027d and `memcpy`\u0027d into the `DEVPATH=` uevent variable that is broadcast to userspace listeners and the uevent helper, so reallocated kernel heap contents are disclosed outside the kernel, and the unterminated `strlen` reads out of bounds past the freed chunk.\nI:H - This is a slab use-after-free where the attacker can spray the freed kmalloc chunk and control the data the kernel then consumes; per UAF-class scoring the reallocation primitive is treated as exploitable for kernel state corruption, and the resulting bogus DEVPATH also drives userspace device management onto the wrong sysfs path.\nA:H - KASAN reports a slab-use-after-free read that can fault and oops when the backing page is freed or under KFENCE/page poisoning, and `kobject_get_path()`\u0027s `retry` loop can spin under a sustained rename storm, both causing denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: vidtv: Fix a null-ptr-deref in vidtv_mux_stop_thread
syzbot report a null-ptr-deref in vidtv_mux_stop_thread. [1]
If dvb->mux is not initialized successfully by vidtv_mux_init() in the
vidtv_start_streaming(), it will trigger null pointer dereference about mux
in vidtv_mux_stop_thread().
Adjust the timing of streaming initialization and check it before
stopping it.
[1]

Summary
In the Linux kernel, the following vulnerability has been resolved:
clocksource: Use migrate_disable() to avoid calling get_random_u32() in atomic context
The following bug report happened with a PREEMPT_RT kernel:
BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48
in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 2012, name: kwatchdog
preempt_count: 1, expected: 0
RCU nest depth: 0, expected: 0
get_random_u32+0x4f/0x110
clocksource_verify_choose_cpus+0xab/0x1a0
clocksource_verify_percpu.part.0+0x6b/0x330
clocksource_watchdog_kthread+0x193/0x1a0
It is due to the fact that clocksource_verify_choose_cpus() is invoked with
preemption disabled. This function invokes get_random_u32() to obtain
random numbers for choosing CPUs. The batched_entropy_32 local lock and/or
the base_crng.lock spinlock in driver/char/random.c will be acquired during
the call. In PREEMPT_RT kernel, they are both sleeping locks and so cannot
be acquired in atomic context.
Fix this problem by using migrate_disable() to allow smp_processor_id() to
be reliably used without introducing atomic context. preempt_disable() is
then called after clocksource_verify_choose_cpus() but before the
clocksource measurement is being run to avoid introducing unexpected
latency.

on kernel built with MAX_SKB_FRAGS=45, where SKB_WITH_OVERHEAD(1024)
is smaller than GRO_MAX_HEAD.
Such built additionally contains the revert of the single page frag cache
so that napi_get_frags() ends up using the page frag allocator, triggering
the splat.
Note that the underlying issue is independent from the mentioned
revert; address it ensuring that the small head cache will fit either TCP
and GRO allocation and updating napi_alloc_skb() and __netdev_alloc_skb()
to select kmalloc() usage for any allocation fitting such cache.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/v3d: Add job to pending list if the reset was skipped
When a CL/CSD job times out, we check if the GPU has made any progress
since the last timeout. If so, instead of resetting the hardware, we skip
the reset and let the timer get rearmed. This gives long-running jobs a
chance to complete.
However, when `timedout_job()` is called, the job in question is removed
from the pending list, which means it won't be automatically freed through
`free_job()`. Consequently, when we skip the reset and keep the job
running, the job won't be freed when it finally completes.
This situation leads to a memory leak, as exposed in [1] and [2].
Similarly to commit 704d3d60fec4 ("drm/etnaviv: don't block scheduler when
GPU is still active"), this patch ensures the job is put back on the
pending list when extending the timeout.

Summary
In the Linux kernel, the following vulnerability has been resolved:
platform/x86: dell-wmi-sysman: Avoid buffer overflow in current_password_store()
If the 'buf' array received from the user contains an empty string, the
'length' variable will be zero. Accessing the 'buf' array element with
index 'length - 1' will result in a buffer overflow.
Add a check for an empty string.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: ucsi: displayport: Fix deadlock
This patch introduces the ucsi_con_mutex_lock / ucsi_con_mutex_unlock
functions to the UCSI driver. ucsi_con_mutex_lock ensures the connector
mutex is only locked if a connection is established and the partner pointer
is valid. This resolves a deadlock scenario where
ucsi_displayport_remove_partner holds con->mutex waiting for
dp_altmode_work to complete while dp_altmode_work attempts to acquire it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: mcast: add RCU protection to mld_newpack()
mld_newpack() can be called without RTNL or RCU being held.
Note that we no longer can use sock_alloc_send_skb() because
ipv6.igmp_sk uses GFP_KERNEL allocations which can sleep.
Instead use alloc_skb() and charge the net->ipv6.igmp_sk
socket under RCU protection.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: stream-ipc: Check for cstream nullity in sof_ipc_msg_data()
The nullity of sps->cstream should be checked similarly as it is done in
sof_set_stream_data_offset() function.
Assuming that it is not NULL if sps->stream is NULL is incorrect and can
lead to NULL pointer dereference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: hfsc: Fix a UAF vulnerability in class handling
This patch fixes a Use-After-Free vulnerability in the HFSC qdisc class
handling. The issue occurs due to a time-of-check/time-of-use condition
in hfsc_change_class() when working with certain child qdiscs like netem
or codel.
The vulnerability works as follows:
1. hfsc_change_class() checks if a class has packets (q.qlen != 0)
2. It then calls qdisc_peek_len(), which for certain qdiscs (e.g.,
codel, netem) might drop packets and empty the queue
3. The code continues assuming the queue is still non-empty, adding
the class to vttree
4. This breaks HFSC scheduler assumptions that only non-empty classes
are in vttree
5. Later, when the class is destroyed, this can lead to a Use-After-Free
The fix adds a second queue length check after qdisc_peek_len() to verify
the queue wasn't emptied.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/v3d: Stop active perfmon if it is being destroyed
If the active performance monitor (`v3d->active_perfmon`) is being
destroyed, stop it first. Currently, the active perfmon is not
stopped during destruction, leaving the `v3d->active_perfmon` pointer
stale. This can lead to undefined behavior and instability.
This patch ensures that the active perfmon is stopped before being
destroyed, aligning with the behavior introduced in commit
7d1fd3638ee3 ("drm/v3d: Stop the active perfmon before being destroyed").

Summary
In the Linux kernel, the following vulnerability has been resolved:
geneve: Fix use-after-free in geneve_find_dev().
syzkaller reported a use-after-free in geneve_find_dev() [0]
without repro.
geneve_configure() links struct geneve_dev.next to
net_generic(net, geneve_net_id)->geneve_list.
The net here could differ from dev_net(dev) if IFLA_NET_NS_PID,
IFLA_NET_NS_FD, or IFLA_TARGET_NETNSID is set.
When dev_net(dev) is dismantled, geneve_exit_batch_rtnl() finally
calls unregister_netdevice_queue() for each dev in the netns,
and later the dev is freed.
However, its geneve_dev.next is still linked to the backend UDP
socket netns.
Then, use-after-free will occur when another geneve dev is created
in the netns.
Let's call geneve_dellink() instead in geneve_destroy_tunnels().

"value": "AV:L - The vulnerability is reached only through RTM_NEWLINK rtnetlink messages sent on an AF_NETLINK socket, requiring local system access. The geneve_list is used solely by the control plane (geneve_configure/geneve_dellink), never by the packet receive path, so no remote packet can trigger it.\nAC:L - The attacker deterministically creates both network namespaces, creates the geneve device cross-netns, destroys the device-owning netns, then creates a second geneve device to dereference the stale list entry \u2014 no race must be won and the dangling pointer persists indefinitely, allowing unhurried heap grooming of the freed 4096-byte slab object.\nPR:L - CAP_NET_ADMIN is required in the owning user namespaces of both netns, but an unprivileged user obtains exactly that with `unshare -Urn` plus a nested `unshare -n`, since both namespaces are owned by their own user_ns and the checks are ns_capable-based. The geneve module is autoloaded on demand from the same unprivileged rtnl_newlink path.\nUI:N - The full sequence is performed by the attacker\u0027s own processes via netlink and namespace file descriptors, with no action by any other user.\nS:U - The use-after-free corrupts kernel heap state and is exploited for kernel privilege escalation within the same security authority; no hypervisor, IOMMU, or other authority boundary is crossed.\nC:H - The stale list entry points into a freed kmalloc-cg-4k object the attacker can reallocate and fill, so the list traversal in geneve_find_dev() follows an attacker-controlled `next` pointer and reads arbitrary kernel addresses, with the -EBUSY/-EPERM/success result acting as a disclosure oracle.\nI:H - Later list_del()/list_add() operations on the corrupted geneve_list write through attacker-controlled prev/next pointers, yielding a classic unlink write-what-where primitive suitable for control-flow hijacking and privilege escalation.\nA:H - The bug is a confirmed slab use-after-free (KASAN slab-use-after-free reported by syzkaller) that reliably corrupts a kernel linked list, causing oops or panic even without successful exploitation."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: iscsi_tcp: Fix UAF during logout when accessing the shost ipaddress
Bug report and analysis from Ding Hui.
During iSCSI session logout, if another task accesses the shost ipaddress
attr, we can get a KASAN UAF report like this:

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI/ASPM: Fix link state exit during switch upstream function removal
Before 456d8aa37d0f ("PCI/ASPM: Disable ASPM on MFD function removal to
avoid use-after-free"), we would free the ASPM link only after the last
function on the bus pertaining to the given link was removed.
That was too late. If function 0 is removed before sibling function,
link->downstream would point to free'd memory after.
After above change, we freed the ASPM parent link state upon any function
removal on the bus pertaining to a given link.
That is too early. If the link is to a PCIe switch with MFD on the upstream
port, then removing functions other than 0 first would free a link which
still remains parent_link to the remaining downstream ports.
The resulting GPFs are especially frequent during hot-unplug, because
pciehp removes devices on the link bus in reverse order.
On that switch, function 0 is the virtual P2P bridge to the internal bus.
Free exactly when function 0 is removed -- before the parent link is
obsolete, but after all subordinate links are gone.

Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring/fdinfo: grab ctx->uring_lock around io_uring_show_fdinfo()
Not everything requires locking in there, which is why the 'has_lock'
variable exists. But enough does that it's a bit unwieldy to manage.
Wrap the whole thing in a ->uring_lock trylock, and just return
with no output if we fail to grab it. The existing trylock() will
already have greatly diminished utility/output for the failure case.
This fixes an issue with reading the SQE fields, if the ring is being
actively resized at the same time.

No remote or adjacent-network data is processed anywhere along the path.\nAC:L - The attacker controls both sides of the race, spinning one thread on resize and another on fdinfo reads, and can widen the window arbitrarily by using a large old ring and a small new ring so the unlocked SQE/CQE dump loop runs for thousands of iterations. No condition outside the attacker\u0027s influence is required.\nPR:L - Any unprivileged local user can create an io_uring instance with `IORING_SETUP_DEFER_TASKRUN|SINGLE_ISSUER` and resize it; no capability check exists on the register path. Reading one\u0027s own `/proc/self/fdinfo/\u003cfd\u003e` always satisfies the `ptrace_may_access(PTRACE_MODE_READ_FSCREDS)` gate in `proc_fdinfo_permission()`.\nUI:N - The entire attack runs inside the attacker\u0027s own process using its own ring fd and its own procfs entries. No other user or administrator has to do anything.\nS:U - The stale-pointer reads, faults, and information disclosure all occur in kernel context against the attacking process\u0027s own kernel objects, within the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - Stale `ctx-\u003erings`/`ctx-\u003esq_array` pointers are dereferenced after `release_pages()`/`vunmap()` frees the old ring regions, and stale `sq_entries`/`sq_mask` combined with the new smaller `ctx-\u003esq_sqes` yield an out-of-bounds read of up to ~2 MB past the SQE region at an offset the attacker chooses through the userspace-mapped `sq_array`. The recovered bytes (`opcode, fd, flags, off, addr, rw_flags, buf_index, user_data`, or a full 128 bytes with SQE128) are `seq_printf()`ed directly into the fdinfo output the attacker reads, giving a repeatable kernel-memory disclosure primitive.\nI:H - This is a use-after-free on freed ring pages that can be recycled into arbitrary kernel allocations and then heap-sprayed by the attacker to steer the derived out-of-bounds dereference, consistent with UAF scoring practice for this subsystem. The leaked heap contents and kernel pointers also defeat KASLR and directly enable control-flow-hijacking exploitation of adjacent kernel state.\nA:H - `ctx-\u003erings` and `ctx-\u003esq_sqes` are transiently NULL during the swap, so `READ_ONCE(r-\u003esq.head)` and `\u0026ctx-\u003esq_sqes[sq_idx \u003c\u003c sq_shift]` produce a NULL-pointer oops, and dereferencing a `vunmap()`\u0027d old region or reading megabytes past the new SQE region faults the kernel. An unprivileged user can trigger these in a tight loop for a reliable panic."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: ipc4-topology: Harden loops for looking up ALH copiers
Other, non DAI copier widgets could have the same stream name (sname) as
the ALH copier and in that case the copier->data is NULL, no alh_data is
attached, which could lead to NULL pointer dereference.
We could check for this NULL pointer in sof_ipc4_prepare_copier_module()
and avoid the crash, but a similar loop in sof_ipc4_widget_setup_comp_dai()
will miscalculate the ALH device count, causing broken audio.
The correct fix is to harden the matching logic by making sure that the
1. widget is a DAI widget - so dai = w->private is valid
2. the dai (and thus the copier) is ALH copier

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Scrub packet on bpf_redirect_peer
When bpf_redirect_peer is used to redirect packets to a device in
another network namespace, the skb isn't scrubbed. That can lead skb
information from one namespace to be "misused" in another namespace.
As one example, this is causing Cilium to drop traffic when using
bpf_redirect_peer to redirect packets that just went through IPsec
decryption to a container namespace. The following pwru trace shows (1)
the packet path from the host's XFRM layer to the container's XFRM
layer where it's dropped and (2) the number of active skb extensions at
each function.

.active_extensions = (__u8)2,
In this case, there are no XFRM policies in the container's network
namespace so the drop is unexpected. When we decrypt the IPsec packet,
the XFRM state used for decryption is set in the skb extensions. This
information is preserved across the netns switch. When we reach the
XFRM policy check in the container's netns, __xfrm_policy_check drops
the packet with LINUX_MIB_XFRMINNOPOLS because a (container-side) XFRM
policy can't be found that matches the (host-side) XFRM state used for
decryption.
This patch fixes this by scrubbing the packet when using
bpf_redirect_peer, as is done on typical netns switches via veth
devices except skb->mark and skb->tstamp are not zeroed.

The exposure is structured and bounded rather than an arbitrary kernel memory read.\nI:H - Multiple security controls in the destination namespace are silently bypassed \u2014 reverse-path filtering is disabled by the stale secpath in `fib_validate_source()`, `nf_conntrack_in()` short-circuits so the container\u0027s stateful firewall/network-policy `ct state` rules match a foreign entry, and `nf_nat_inet_fn()` applies the host\u0027s NAT binding instead of the container\u0027s own `DNAT`/`REDIRECT` interception rules; conversely container-side `nft_ct` can write `ct mark`/`ct secmark` onto a host-namespace conntrack object that drives host policy routing and SELinux packet decisions.\nA:H - The commit documents the confirmed real-world effect: the leaked secpath makes `__xfrm_policy_check()` drop packets with `LINUX_MIB_XFRMINNOPOLS` in a container that has no XFRM policy, producing sustained and total loss of network connectivity for affected containers. This is a persistent denial of the pod\u0027s network service, not mere degradation."

Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: client: Avoid race in open_cached_dir with lease breaks
A pre-existing valid cfid returned from find_or_create_cached_dir might
race with a lease break, meaning open_cached_dir doesn't consider it
valid, and thinks it's newly-constructed. This leaks a dentry reference
if the allocation occurs before the queued lease break work runs.
Avoid the race by extending holding the cfid_list_lock across
find_or_create_cached_dir and when the result is checked.

The same class of race in this file was reproduced by its author with two ordinary shell loops.\nPR:N - The attacking SMB server holds no privileges or credentials on the victim client; it merely answers a share the client has already mounted. The local half needs nothing beyond stat() or readdir() on the mount, available to any unprivileged account with no capabilities.\nUI:N - The mount is a pre-existing configuration, not an exploit-time action, and no deliberate victim participation is needed \u2014 ordinary background directory access from any process supplies the local half, and the server can force re-opens on demand by breaking the lease.\nS:U - The leaked dentry/inode references, corrupted superblock teardown and crash are all confined to the client kernel\u0027s own security authority. No VM, IOMMU or sandbox boundary is crossed.\nC:N - The defect is a lost reference count; no memory is read out of bounds and no kernel data is copied to the attacker.

Summary
In the Linux kernel, the following vulnerability has been resolved:
of: module: add buffer overflow check in of_modalias()
In of_modalias(), if the buffer happens to be too small even for the 1st
snprintf() call, the len parameter will become negative and str parameter
(if not NULL initially) will point beyond the buffer's end. Add the buffer
overflow check after the 1st snprintf() call and fix such check after the
strlen() call (accounting for the terminating NUL char).

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: csa unmap use uninterruptible lock
After process exit to unmap csa and free GPU vm, if signal is accepted
and then waiting to take vm lock is interrupted and return, it causes
memory leaking and below warning backtrace.
Change to use uninterruptible wait lock fix the issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: core: flush gadget workqueue after device removal
device_del() can lead to new work being scheduled in gadget->work
workqueue. This is observed, for example, with the dwc3 driver with the
following call stack:
device_del()
gadget_unbind_driver()
usb_gadget_disconnect_locked()
dwc3_gadget_pullup()
dwc3_gadget_soft_disconnect()
usb_gadget_set_state()
schedule_work(&gadget->work)
Move flush_work() after device_del() to ensure the workqueue is cleaned
up.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: correct the order of prelim_ref arguments in btrfs__prelim_ref
btrfs_prelim_ref() calls the old and new reference variables in the
incorrect order. This causes a NULL pointer dereference because oldref
is passed as NULL to trace_btrfs_prelim_ref_insert().
Note, trace_btrfs_prelim_ref_insert() is being called with newref as
oldref (and oldref as NULL) on purpose in order to print out
the values of newref.
To reproduce:
echo 1 > /sys/kernel/debug/tracing/events/btrfs/btrfs_prelim_ref_insert/enable
Perform some writeback operations.
Backtrace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSD: fix hang in nfsd4_shutdown_callback
If nfs4_client is in courtesy state then there is no point to send
the callback. This causes nfsd4_shutdown_callback to hang since
cl_cb_inflight is not 0. This hang lasts about 15 minutes until TCP
notifies NFSD that the connection was dropped.
This patch modifies nfsd4_run_cb_work to skip the RPC call if
nfs4_client is in courtesy state.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: algif_hash - fix double free in hash_accept
If accept(2) is called on socket type algif_hash with
MSG_MORE flag set and crypto_ahash_import fails,
sk2 is freed. However, it is also freed in af_alg_release,
leading to slab-use-after-free error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mptcp: pm: only set fullmesh for subflow endp
With the in-kernel path-manager, it is possible to change the 'fullmesh'
flag. The code in mptcp_pm_nl_fullmesh() expects to change it only on
'subflow' endpoints, to recreate more or less subflows using the linked
address.
Unfortunately, the set_flags() hook was a bit more permissive, and
allowed 'implicit' endpoints to get the 'fullmesh' flag while it is not
allowed before.
That's what syzbot found, triggering the following warning:

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: target: iscsi: Fix timeout on deleted connection
NOPIN response timer may expire on a deleted connection and crash with
such logs:
Did not receive response to NOPIN on CID: 0, failing connection for I_T Nexus (null),i,0x00023d000125,iqn.2017-01.com.iscsi.target,t,0x3d
BUG: Kernel NULL pointer dereference on read at 0x00000000
NIP strlcpy+0x8/0xb0
LR iscsit_fill_cxn_timeout_err_stats+0x5c/0xc0 [iscsi_target_mod]
Call Trace:
iscsit_handle_nopin_response_timeout+0xfc/0x120 [iscsi_target_mod]
call_timer_fn+0x58/0x1f0
run_timer_softirq+0x740/0x860
__do_softirq+0x16c/0x420
irq_exit+0x188/0x1c0
timer_interrupt+0x184/0x410
That is because nopin response timer may be re-started on nopin timer
expiration.
Stop nopin timer before stopping the nopin response timer to be sure
that no one of them will be re-started.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix invalid context error in dml helper
[Why]
"BUG: sleeping function called from invalid context" error.
after:
"drm/amd/display: Protect FPU in dml2_validate()/dml21_validate()"
The populate_dml_plane_cfg_from_plane_state() uses the GFP_KERNEL flag
for memory allocation, which shouldn't be used in atomic contexts.
The allocation is needed only for using another helper function
get_scaler_data_for_plane().
[How]
Modify helpers to pass a pointer to scaler_data within existing context,
eliminating the need for dynamic memory allocation/deallocation
and copying.
(cherry picked from commit bd3e84bc98f81b44f2c43936bdadc3241d654259)

Summary
In the Linux kernel, the following vulnerability has been resolved:
batman-adv: Drop unmanaged ELP metric worker
The ELP worker needs to calculate new metric values for all neighbors
"reachable" over an interface. Some of the used metric sources require
locks which might need to sleep. This sleep is incompatible with the RCU
list iterator used for the recorded neighbors. The initial approach to work
around of this problem was to queue another work item per neighbor and then
run this in a new context.
Even when this solved the RCU vs might_sleep() conflict, it has a major
problems: Nothing was stopping the work item in case it is not needed
anymore - for example because one of the related interfaces was removed or
the batman-adv module was unloaded - resulting in potential invalid memory
accesses.
Directly canceling the metric worker also has various problems:
* cancel_work_sync for a to-be-deactivated interface is called with
rtnl_lock held. But the code in the ELP metric worker also tries to use
rtnl_lock() - which will never return in this case. This also means that
cancel_work_sync would never return because it is waiting for the worker
to finish.
* iterating over the neighbor list for the to-be-deactivated interface is
currently done using the RCU specific methods. Which means that it is
possible to miss items when iterating over it without the associated
spinlock - a behaviour which is acceptable for a periodic metric check
but not for a cleanup routine (which must "stop" all still running
workers)
The better approch is to get rid of the per interface neighbor metric
worker and handle everything in the interface worker. The original problems
are solved by:
* creating a list of neighbors which require new metric information inside
the RCU protected context, gathering the metric according to the new list
outside the RCU protected context
* only use rcu_trylock inside metric gathering code to avoid a deadlock
when the cancel_delayed_work_sync is called in the interface removal code
(which is called with the rtnl_lock held)

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/ism: add release function for struct device
According to device_release() in /drivers/base/core.c,
a device without a release function is a broken device
and must be fixed.
The current code directly frees the device after calling device_add()
without waiting for other kernel parts to release their references.
Thus, a reference could still be held to a struct device,
e.g., by sysfs, leading to potential use-after-free
issues if a proper release function is not set.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: mctp: Don't access ifa_index when missing
In mctp_dump_addrinfo, ifa_index can be used to filter interfaces, but
only when the struct ifaddrmsg is provided. Otherwise it will be
comparing to uninitialised memory - reproducible in the syzkaller case from
dhcpd, or busybox "ip addr show".
The kernel MCTP implementation has always filtered by ifa_index, so
existing userspace programs expecting to dump MCTP addresses must
already be passing a valid ifa_index value (either 0 or a real index).

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/gem: prevent integer overflow in msm_ioctl_gem_submit()
The "submit->cmd[i].size" and "submit->cmd[i].offset" variables are u32
values that come from the user via the submit_lookup_cmds() function.
This addition could lead to an integer wrapping bug so use size_add()
to prevent that.

Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: sn-f-ospi: Fix division by zero
When there is no dummy cycle in the spi-nor commands, both dummy bus cycle
bytes and width are zero. Because of the cpu's warning when divided by
zero, the warning should be avoided. Return just zero to avoid such
calculations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm cache: prevent BUG_ON by blocking retries on failed device resumes
A cache device failing to resume due to mapping errors should not be
retried, as the failure leaves a partially initialized policy object.
Repeating the resume operation risks triggering BUG_ON when reloading
cache mappings into the incomplete policy object.
Reproduce steps:
1. create a cache metadata consisting of 512 or more cache blocks,
with some mappings stored in the first array block of the mapping
array. Here we use cache_restore v1.0 to build the metadata.
cat <<EOF >> cmeta.xml
<superblock uuid="" block_size="128" nr_cache_blocks="512" \
policy="smq" hint_width="4">
<mappings>
<mapping cache_block="0" origin_block="0" dirty="false"/>
</mappings>
</superblock>
EOF
dmsetup create cmeta --table "0 8192 linear /dev/sdc 0"
cache_restore -i cmeta.xml -o /dev/mapper/cmeta --metadata-version=2
dmsetup remove cmeta
2. wipe the second array block of the mapping array to simulate
data degradations.
mapping_root=$(dd if=/dev/sdc bs=1c count=8 skip=192 \
2>/dev/null | hexdump -e '1/8 "%u\n"')
ablock=$(dd if=/dev/sdc bs=1c count=8 skip=$((4096*mapping_root+2056)) \
2>/dev/null | hexdump -e '1/8 "%u\n"')
dd if=/dev/zero of=/dev/sdc bs=4k count=1 seek=$ablock
3. try bringing up the cache device. The resume is expected to fail
due to the broken array block.
dmsetup create cmeta --table "0 8192 linear /dev/sdc 0"
dmsetup create cdata --table "0 65536 linear /dev/sdc 8192"
dmsetup create corig --table "0 524288 linear /dev/sdc 262144"
dmsetup create cache --notable
dmsetup load cache --table "0 524288 cache /dev/mapper/cmeta \
/dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"
dmsetup resume cache
4. try resuming the cache again. An unexpected BUG_ON is triggered
while loading cache mappings.
dmsetup resume cache

Summary
In the Linux kernel, the following vulnerability has been resolved:
__legitimize_mnt(): check for MNT_SYNC_UMOUNT should be under mount_lock
... or we risk stealing final mntput from sync umount - raising mnt_count
after umount(2) has verified that victim is not busy, but before it
has set MNT_SYNC_UMOUNT; in that case __legitimize_mnt() doesn't see
that it's safe to quietly undo mnt_count increment and leaves dropping
the reference to caller, where it'll be a full-blown mntput().
Check under mount_lock is needed; leaving the current one done before
taking that makes no sense - it's nowhere near common enough to bother
with.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Fix uninitialized memcache pointer in user_mem_abort()
Commit fce886a60207 ("KVM: arm64: Plumb the pKVM MMU in KVM") made the
initialization of the local memcache variable in user_mem_abort()
conditional, leaving a codepath where it is used uninitialized via
kvm_pgtable_stage2_map().
This can fail on any path that requires a stage-2 allocation
without transition via a permission fault or dirty logging.
Fix this by making sure that memcache is always valid.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/mm: Eliminate window where TLB flushes may be inadvertently skipped
tl;dr: There is a window in the mm switching code where the new CR3 is
set and the CPU should be getting TLB flushes for the new mm. But
should_flush_tlb() has a bug and suppresses the flush. Fix it by
widening the window where should_flush_tlb() sends an IPI.
Long Version:
=== History ===
There were a few things leading up to this.
First, updating mm_cpumask() was observed to be too expensive, so it was
made lazier. But being lazy caused too many unnecessary IPIs to CPUs
due to the now-lazy mm_cpumask(). So code was added to cull
mm_cpumask() periodically[2]. But that culling was a bit too aggressive
and skipped sending TLB flushes to CPUs that need them. So here we are
again.
=== Problem ===
The too-aggressive code in should_flush_tlb() strikes in this window:
// Turn on IPIs for this CPU/mm combination, but only
// if should_flush_tlb() agrees:
cpumask_set_cpu(cpu, mm_cpumask(next));
next_tlb_gen = atomic64_read(&next->context.tlb_gen);
choose_new_asid(next, next_tlb_gen, &new_asid, &need_flush);
load_new_mm_cr3(need_flush);
// ^ After 'need_flush' is set to false, IPIs *MUST*
// be sent to this CPU and not be ignored.
this_cpu_write(cpu_tlbstate.loaded_mm, next);
// ^ Not until this point does should_flush_tlb()
// become true!
should_flush_tlb() will suppress TLB flushes between load_new_mm_cr3()
and writing to 'loaded_mm', which is a window where they should not be
suppressed. Whoops.
=== Solution ===
Thankfully, the fuzzy "just about to write CR3" window is already marked
with loaded_mm==LOADED_MM_SWITCHING. Simply checking for that state in
should_flush_tlb() is sufficient to ensure that the CPU is targeted with
an IPI.
This will cause more TLB flush IPIs. But the window is relatively small
and I do not expect this to cause any kind of measurable performance
impact.
Update the comment where LOADED_MM_SWITCHING is written since it grew
yet another user.
Peter Z also raised a concern that should_flush_tlb() might not observe
'loaded_mm' and 'is_lazy' in the same order that switch_mm_irqs_off()
writes them. Add a barrier to ensure that they are observed in the
order they are written.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFS/localio: Fix a race in nfs_local_open_fh()
Once the clp->cl_uuid.lock has been dropped, another CPU could come in
and free the struct nfsd_file that was just added. To prevent that from
happening, take the RCU read lock before dropping the spin lock.

The window is repeatedly retriable at will and widened by preemption under CPU pressure.\nPR:L - Any unprivileged local user with access to files on a LOCALIO-enabled NFS mount can drive both sides purely with read/write/close syscalls; no capability check exists anywhere along nfs_generic_pg_pgios \u2192 nfs_local_open_fh.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vrf: use RCU protection in l3mdev_l3_out()
l3mdev_l3_out() can be called without RCU being held:
raw_sendmsg()
ip_push_pending_frames()
ip_send_skb()
ip_local_out()
__ip_local_out()
l3mdev_ip_out()
Add rcu_read_lock() / rcu_read_unlock() pair to avoid
a potential UAF.
