Summary
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: s32cc: fix uninitialized memory in s32_pinctrl_desc
s32_pinctrl_desc is allocated with devm_kmalloc(), but not all of its
fields are initialized. Notably, num_custom_params is used in
pinconf_generic_parse_dt_config(), resulting in intermittent allocation
errors, such as the following splat when probing i2c-imx:
WARNING: CPU: 0 PID: 176 at mm/page_alloc.c:4795 __alloc_pages_noprof+0x290/0x300

This results in later parse failures that can cause issues in dependent
drivers:

i2c i2c-2: IMX I2C adapter registered
Fix this by initializing s32_pinctrl_desc with devm_kzalloc() instead of
devm_kmalloc() in s32_pinctrl_probe(), which sets the previously
uninitialized fields to zero.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: fix wrong fallback logic for FDIR
When adding a FDIR filter, if ice_vc_fdir_set_irq_ctx returns failure,
the inserted fdir entry will not be removed and if ice_vc_fdir_write_fltr
returns failure, the fdir context info for irq handler will not be cleared
which may lead to inconsistent or memory leak issue. This patch refines
failure cases to resolve this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix NULL pointer dereference in snd_usb_mixer_controls_badd
In snd_usb_create_streams(), for UAC version 3 devices, the Interface
Association Descriptor (IAD) is retrieved via usb_ifnum_to_if(). If this
call fails, a fallback routine attempts to obtain the IAD from the next
interface and sets a BADD profile. However, snd_usb_mixer_controls_badd()
assumes that the IAD retrieved from usb_ifnum_to_if() is always valid,
without performing a NULL check. This can lead to a NULL pointer
dereference when usb_ifnum_to_if() fails to find the interface descriptor.
This patch adds a NULL pointer check after calling usb_ifnum_to_if() in
snd_usb_mixer_controls_badd() to prevent the dereference.
This issue was discovered by syzkaller, which triggered the bug by sending
a crafted USB device descriptor.

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/cpum_sf: Handle CPU hotplug remove during sampling
CPU hotplug remove handling triggers the following function
call sequence:
CPUHP_AP_PERF_S390_SF_ONLINE --> s390_pmu_sf_offline_cpu()
...
CPUHP_AP_PERF_ONLINE --> perf_event_exit_cpu()
The s390 CPUMF sampling CPU hotplug handler invokes:
s390_pmu_sf_offline_cpu()
+--> cpusf_pmu_setup()
+--> setup_pmc_cpu()
+--> deallocate_buffers()
This function de-allocates all sampling data buffers (SDBs) allocated
for that CPU at event initialization. It also clears the
PMU_F_RESERVED bit. The CPU is gone and can not be sampled.
With the event still being active on the removed CPU, the CPU event
hotplug support in kernel performance subsystem triggers the
following function calls on the removed CPU:
perf_event_exit_cpu()
+--> perf_event_exit_cpu_context()
+--> __perf_event_exit_context()
+--> __perf_remove_from_context()
+--> event_sched_out()
+--> cpumsf_pmu_del()
+--> cpumsf_pmu_stop()
+--> hw_perf_event_update()
to stop and remove the event. During removal of the event, the
sampling device driver tries to read out the remaining samples from
the sample data buffers (SDBs). But they have already been freed
(and may have been re-assigned). This may lead to a use after free
situation in which case the samples are most likely invalid. In the
best case the memory has not been reassigned and still contains
valid data.
Remedy this situation and check if the CPU is still in reserved
state (bit PMU_F_RESERVED set). In this case the SDBs have not been
released an contain valid data. This is always the case when
the event is removed (and no CPU hotplug off occured).
If the PMU_F_RESERVED bit is not set, the SDB buffers are gone.

The double free is caused by an unnecessary bio_put() in the
if(is_badblock(...)) error path in raid5_read_one_chunk().
The error path was moved ahead of bio_alloc_clone() in c82aa1b76787c
("md/raid5: move checking badblock before clone bio in
raid5_read_one_chunk"). The previous code checked and freed align_bio
which required a bio_put. After the move that is no longer needed as
raid_bio is returned to the control of the common io path which
performs its own endio resulting in a double free on bad device blocks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: verify orphan file size is not too big
In principle orphan file can be arbitrarily large. However orphan replay
needs to traverse it all and we also pin all its buffers in memory. Thus
filesystems with absurdly large orphan files can lead to big amounts of
memory consumed. Limit orphan file size to a sane value and also use
kvmalloc() for allocating array of block descriptor structures to avoid
large order allocations for sane but large orphan files.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mailbox: zynq-ipi: fix error handling while device_register() fails
If device_register() fails, it has two issues:
1. The name allocated by dev_set_name() is leaked.
2. The parent of device is not NULL, device_unregister() is called
in zynqmp_ipi_free_mboxes(), it will lead a kernel crash because
of removing not added device.
Call put_device() to give up the reference, so the name is freed in
kobject_cleanup(). Add device registered check in zynqmp_ipi_free_mboxes()
to avoid null-ptr-deref.

Summary
In the Linux kernel, the following vulnerability has been resolved:
pstore: Avoid kcore oops by vmap()ing with VM_IOREMAP
An oops can be induced by running 'cat /proc/kcore > /dev/null' on
devices using pstore with the ram backend because kmap_atomic() assumes
lowmem pages are accessible with __va().

During early boot, memblock reserves the pages for the ramoops reserved
memory node in DT that would otherwise be part of the direct lowmem
mapping. Pstore's ram backend reuses those reserved pages to change the
memory type (writeback or non-cached) by passing the pages to vmap()
(see pfn_to_page() usage in persistent_ram_vmap() for more details) with
specific flags. When read_kcore() starts iterating over the vmalloc
region, it runs over the virtual address that vmap() returned for
ramoops. In aligned_vread() the virtual address is passed to
vmalloc_to_page() which returns the page struct for the reserved lowmem
area. That lowmem page is passed to kmap_atomic(), which effectively
calls page_to_virt() that assumes a lowmem page struct must be directly
accessible with __va() and friends. These pages are mapped via vmap()
though, and the lowmem mapping was never made, so accessing them via the
lowmem virtual address oopses like above.
Let's side-step this problem by passing VM_IOREMAP to vmap(). This will
tell vread() to not include the ramoops region in the kcore. Instead the
area will look like a bunch of zeros. The alternative is to teach kmap()
about vmalloc areas that intersect with lowmem. Presumably such a change
isn't a one-liner, and there isn't much interest in inspecting the
ramoops region in kcore files anyway, so the most expedient route is
taken for now.

When read_kcore() starts iterating over the vmalloc\nregion, it runs over the virtual address that vmap() returned for\nramoops. In aligned_vread() the virtual address is passed to\nvmalloc_to_page() which returns the page struct for the reserved lowmem\narea. That lowmem page is passed to kmap_atomic(), which effectively\ncalls page_to_virt() that assumes a lowmem page struct must be directly\naccessible with __va() and friends. These pages are mapped via vmap()\nthough, and the lowmem mapping was never made, so accessing them via the\nlowmem virtual address oopses like above.\n\nLet\u0027s side-step this problem by passing VM_IOREMAP to vmap(). This will\ntell vread() to not include the ramoops region in the kcore. Instead the\narea will look like a bunch of zeros. The alternative is to teach kmap()\nabout vmalloc areas that intersect with lowmem. Presumably such a change\nisn\u0027t a one-liner, and there isn\u0027t much interest in inspecting the\nramoops region in kcore files anyway, so the most expedient route is\ntaken for now."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: dice: fix buffer overflow in detect_stream_formats()
The function detect_stream_formats() reads the stream_count value directly
from a FireWire device without validating it. This can lead to
out-of-bounds writes when a malicious device provides a stream_count value
greater than MAX_STREAMS.
Fix by applying the same validation to both TX and RX stream counts in
detect_stream_formats().

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: hugetlb: fix UAF in hugetlb_handle_userfault
The vma_lock and hugetlb_fault_mutex are dropped before handling userfault
and reacquire them again after handle_userfault(), but reacquire the
vma_lock could lead to UAF[1,2] due to the following race,
hugetlb_fault
hugetlb_no_page
/*unlock vma_lock */
hugetlb_handle_userfault
handle_userfault
/* unlock mm->mmap_lock*/
vm_mmap_pgoff
do_mmap
mmap_region
munmap_vma_range
/* clean old vma */
/* lock vma_lock again <--- UAF */
/* unlock vma_lock */
Since the vma_lock will unlock immediately after
hugetlb_handle_userfault(), let's drop the unneeded lock and unlock in
hugetlb_handle_userfault() to fix the issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: cadence: Check for the existence of cdns_pcie::ops before using it
cdns_pcie::ops might not be populated by all the Cadence glue drivers. This
is going to be true for the upcoming Sophgo platform which doesn't set the
ops.
Hence, add a check to prevent NULL pointer dereference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix race between balance and cancel/pause
Syzbot reported a panic that looks like this:
assertion failed: fs_info->exclusive_operation == BTRFS_EXCLOP_BALANCE_PAUSED, in fs/btrfs/ioctl.c:465
------------[ cut here ]------------
kernel BUG at fs/btrfs/messages.c:259!
RIP: 0010:btrfs_assertfail+0x2c/0x30 fs/btrfs/messages.c:259

The reproducer is running a balance and a cancel or pause in parallel.
The way balance finishes is a bit wonky, if we were paused we need to
save the balance_ctl in the fs_info, but clear it otherwise and cleanup.
However we rely on the return values being specific errors, or having a
cancel request or no pause request. If balance completes and returns 0,
but we have a pause or cancel request we won't do the appropriate
cleanup, and then the next time we try to start a balance we'll trip
this ASSERT.
The error handling is just wrong here, we always want to clean up,
unless we got -ECANCELLED and we set the appropriate pause flag in the
exclusive op. With this patch the reproducer ran for an hour without
tripping, previously it would trip in less than a few minutes.

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlx5: Fix default values in create CQ
Currently, CQs without a completion function are assigned the
mlx5_add_cq_to_tasklet function by default. This is problematic since
only user CQs created through the mlx5_ib driver are intended to use
this function.
Additionally, all CQs that will use doorbells instead of polling for
completions must call mlx5_cq_arm. However, the default CQ creation flow
leaves a valid value in the CQ's arm_db field, allowing FW to send
interrupts to polling-only CQs in certain corner cases.
These two factors would allow a polling-only kernel CQ to be triggered
by an EQ interrupt and call a completion function intended only for user
CQs, causing a null pointer exception.
Some areas in the driver have prevented this issue with one-off fixes
but did not address the root cause.
This patch fixes the described issue by adding defaults to the create CQ
flow. It adds a default dummy completion function to protect against
null pointer exceptions, and it sets an invalid command sequence number
by default in kernel CQs to prevent the FW from sending an interrupt to
the CQ until it is armed. User CQs are responsible for their own
initialization values.
Callers of mlx5_core_create_cq are responsible for changing the
completion function and arming the CQ per their needs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
hfs/hfsplus: avoid WARN_ON() for sanity check, use proper error handling
Commit 55d1cbbbb29e ("hfs/hfsplus: use WARN_ON for sanity check") fixed
a build warning by turning a comment into a WARN_ON(), but it turns out
that syzbot then complains because it can trigger said warning with a
corrupted hfs image.
The warning actually does warn about a bad situation, but we are much
better off just handling it as the error it is. So rather than warn
about us doing bad things, stop doing the bad things and return -EIO.
While at it, also fix a memory leak that was introduced by an earlier
fix for a similar syzbot warning situation, and add a check for one case
that historically wasn't handled at all (ie neither comment nor
subsequent WARN_ON).

Summary
In the Linux kernel, the following vulnerability has been resolved:
perf/x86/intel: Fix KASAN global-out-of-bounds warning
When running "perf mem record" command on CWF, the below KASAN
global-out-of-bounds warning is seen.
==================================================================
BUG: KASAN: global-out-of-bounds in cmt_latency_data+0x176/0x1b0
Read of size 4 at addr ffffffffb721d000 by task dtlb/9850
Call Trace:
kasan_report+0xb8/0xf0
cmt_latency_data+0x176/0x1b0
setup_arch_pebs_sample_data+0xf49/0x2560
intel_pmu_drain_arch_pebs+0x577/0xb00
handle_pmi_common+0x6c4/0xc80
The issue is caused by below code in __grt_latency_data(). The code
tries to access x86_hybrid_pmu structure which doesn't exist on
non-hybrid platform like CWF.
WARN_ON_ONCE(hybrid_pmu(event->pmu)->pmu_type == hybrid_big)
So add is_hybrid() check before calling this WARN_ON_ONCE to fix the
global-out-of-bounds access issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/pseries: fix possible memory leak in ibmebus_bus_init()
If device_register() returns error in ibmebus_bus_init(), name of kobject
which is allocated in dev_set_name() called in device_add() is leaked.
As comment of device_add() says, it should call put_device() to drop
the reference count that was set in device_initialize() when it fails,
so the name can be freed in kobject_cleanup().

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/proc: fix uaf in proc_readdir_de()
Pde is erased from subdir rbtree through rb_erase(), but not set the node
to EMPTY, which may result in uaf access. We should use RB_CLEAR_NODE()
set the erased node to EMPTY, then pde_subdir_next() will return NULL to
avoid uaf access.
We found an uaf issue while using stress-ng testing, need to run testcase
getdent and tun in the same time. The steps of the issue is as follows:
1) use getdent to traverse dir /proc/pid/net/dev_snmp6/, and current
pde is tun3;
2) in the [time windows] unregister netdevice tun3 and tun2, and erase
them from rbtree. erase tun3 first, and then erase tun2. the
pde(tun2) will be released to slab;
3) continue to getdent process, then pde_subdir_next() will return
pde(tun2) which is released, it will case uaf access.

The sequence is unbounded and retryable.\nPR:L - Reading `/proc/self/net/dev_snmp6` requires no privilege at all, and the removal side needs only `CAP_NET_ADMIN` inside an attacker-created user+network namespace (`unshare -Urn`), which any unprivileged user obtains on default distro configurations. No real root in the init namespace is needed.\nUI:N - The attacker drives both the directory iteration and the proc-entry removal from its own threads; no victim action or cooperation is required.\nS:U - The corruption is confined to kernel heap objects managed by the same kernel security authority; there is no VM, IOMMU, or hypervisor boundary crossed.\nC:H - `dir_emit(ctx, de-\u003ename, de-\u003enamelen, ...)` reads the `char *name` pointer and `u8 namelen` out of the freed `proc_dir_entry` and copies up to 255 bytes from that pointer directly into the user\u0027s dirent buffer, giving a repeatable arbitrary-kernel-memory read into userspace once the slab object is reclaimed with attacker-influenced content.\nI:H - The use-after-free yields `refcount_inc()`/`refcount_dec_and_test()` on freed memory plus `pde_free()` performing `kfree(pde-\u003edata)`/`kfree(pde-\u003ename)` on pointers read from the reallocated object, providing arbitrary-free and heap-corruption primitives that are a standard basis for local privilege escalation.\nA:H - Dereferencing stale rbtree links into freed slab memory reliably produces a kernel oops/panic (as observed under stress-ng with getdents+tun), and the race can be re-run indefinitely to crash the system on demand."

Summary
In the Linux kernel, the following vulnerability has been resolved:
most: usb: fix double free on late probe failure
The MOST subsystem has a non-standard registration function which frees
the interface on registration failures and on deregistration.
This unsurprisingly leads to bugs in the MOST drivers, and a couple of
recent changes turned a reference underflow and use-after-free in the
USB driver into several double free and a use-after-free on late probe
failures.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: fix crash while sending Action Frames in standalone AP Mode
Currently, whenever there is a need to transmit an Action frame,
the brcmfmac driver always uses the P2P vif to send the "actframe" IOVAR to
firmware. The P2P interfaces were available when wpa_supplicant is managing
the wlan interface.
However, the P2P interfaces are not created/initialized when only hostapd
is managing the wlan interface. And if hostapd receives an ANQP Query REQ
Action frame even from an un-associated STA, the brcmfmac driver tries
to use an uninitialized P2P vif pointer for sending the IOVAR to firmware.
This NULL pointer dereferencing triggers a driver crash.

Fix this, by always using the vif corresponding to the wdev on which the
Action frame Transmission request was initiated by the userspace. This way,
even if P2P vif is not available, the IOVAR is sent to firmware on AP vif
and the ANQP Query RESP Action frame is transmitted without crashing the
driver.
Move init_completion() for "send_af_done" from brcmf_p2p_create_p2pdev()
to brcmf_p2p_attach(). Because the former function would not get executed
when only hostapd is managing wlan interface, and it is not safe to do
reinit_completion() later in brcmf_p2p_tx_action_frame(), without any prior
init_completion().
And in the brcmf_p2p_tx_action_frame() function, the condition check for
P2P Presence response frame is not needed, since the wpa_supplicant is
properly sending the P2P Presense Response frame on the P2P-GO vif instead
of the P2P-Device vif.

Looks like it tries to create a func_proto which return type is
decl_tag. For the details, see Martin's spot on analysis in [0].

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: fix potential memory leak in mlx5e_init_rep_rx
The memory pointed to by the priv->rx_res pointer is not freed in the error
path of mlx5e_init_rep_rx, which can lead to a memory leak. Fix by freeing
the memory in the error path, thereby making the error path identical to
mlx5e_cleanup_rep_rx().

Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: core: Fix kernel panic when remove non-standard SDIO card
SDIO tuple is only allocated for standard SDIO card, especially it causes
memory corruption issues when the non-standard SDIO card has removed, which
is because the card device's reference counter does not increase for it at
sdio_init_func(), but all SDIO card device reference counter gets decreased
at sdio_release_func().

Summary
In the Linux kernel, the following vulnerability has been resolved:
accel/ivpu: Fix race condition when unbinding BOs
Fix 'Memory manager not clean during takedown' warning that occurs
when ivpu_gem_bo_free() removes the BO from the BOs list before it
gets unmapped. Then file_priv_unbind() triggers a warning in
drm_mm_takedown() during context teardown.
Protect the unmapping sequence with bo_list_lock to ensure the BO is
always fully unmapped when removed from the list. This ensures the BO
is either fully unmapped at context teardown time or present on the
list and unmapped by file_priv_unbind().

No capability, authentication, DRM-master, or root-only check applies.\nUI:N - Exploitation requires only attacker-initiated ioctls and descriptor teardown, with no action by another user.\nS:U - The resulting corruption affects the host kernel within the same security authority; it does not inherently cross a VM or IOMMU boundary.\nC:H - The race can access a freed MMU context and freed page-table structures, producing exploitable kernel memory corruption. Successful kernel code execution would permit arbitrary kernel-memory disclosure.\nI:H - The stale unmap writes through freed page-table pointers, while stale drm_mm removal mutates list and red-black-tree state in freed or reclaimed memory. Attacker-directed heap reclamation could turn this into arbitrary writes or control-flow hijacking.\nA:H - A mapped BO can cause access to freed or unmapped page-table storage and a destroyed context, resulting in an oops or kernel panic.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/powerplay/psm: Fix memory leak in power state init
Commit 902bc65de0b3 ("drm/amdgpu/powerplay/psm: return an error in power

Summary
In the Linux kernel, the following vulnerability has been resolved:
mptcp: fix race condition in mptcp_schedule_work()
syzbot reported use-after-free in mptcp_schedule_work() [1]
Issue here is that mptcp_schedule_work() schedules a work,
then gets a refcount on sk->sk_refcnt if the work was scheduled.
This refcount will be released by mptcp_worker().
[A] if (schedule_work(...)) {
[B] sock_hold(sk);
return true;
}
Problem is that mptcp_worker() can run immediately and complete before [B]
We need instead :
sock_hold(sk);
if (schedule_work(...))
return true;
sock_put(sk);
[1]
refcount_t: addition on 0; use-after-free.

"value": "AV:N - The vulnerable function is reached directly from the packet receive path (`tcp_input.c` \u2192 `mptcp_incoming_options()` on received MP_FASTCLOSE and DATA_FIN options) and from the mp_fail/close timeouts armed by remote peer behaviour such as a bad DSS checksum or subflow reset. A remote MPTCP peer drives the connection state machine that schedules the work, making this reachable over the network with no local access.\nAC:L - The attacker controls both sides of the race by opening and tearing down large numbers of MPTCP connections/subflows, generating an unbounded stream of work-scheduling events (timer expiry, MP_FASTCLOSE, DATA_FIN, subflow close) that each retry the race. The window is further widened on threaded-softirq/PREEMPT_RT kernels (as in the syzbot trace, `run_ktimerd`) and under vCPU preemption in virtualized deployments, so success is achievable at will through repetition.\nPR:N - No credentials or capabilities are checked anywhere on the path; a remote peer of an MPTCP connection (or an unauthenticated client connecting to an MPTCP-enabled listener) triggers the option-parsing and timeout paths in softirq context. Locally the same code is reachable by any unprivileged user simply creating and closing `IPPROTO_MPTCP` sockets.\nUI:N - The race is triggered entirely by attacker-generated traffic and normal MPTCP connection teardown/timeout processing. No victim action of any kind is required.\nS:U - The corruption is confined to kernel memory within the same security authority; there is no crossing of a VM, IOMMU, or sandbox boundary. This is a standard in-kernel use-after-free.\nC:H - The `struct sock` is freed while still referenced, and the freed slab object can be reallocated and read back through the still-live MPTCP socket/timer state, exposing arbitrary kernel heap contents. Use-after-free on a socket object gives an attacker control over the contents of the freed object, enabling kernel memory disclosure.\nI:H - After the premature free, `sock_hold()` performs a refcount increment write at a fixed offset into freed (and potentially reallocated) memory, and the trailing `sock_put()` can re-enter `sk_free()`/`sk_destruct` on that object, producing a double free and freelist corruption. These are established primitives for heap grooming and control-flow hijacking, i.e. full integrity loss.\nA:H - The reported symptom is a refcount underflow warning followed by use-after-free of the MPTCP socket, which readily results in an oops or panic when the freed object is dereferenced by the timer, workqueue, or destructor path. Any UAF of this kind reliably crashes the kernel, and it can be triggered repeatedly."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: snic: Fix possible UAF in snic_tgt_create()
Smatch reports a warning as follows:
drivers/scsi/snic/snic_disc.c:307 snic_tgt_create() warn:
'&tgt->list' not removed from list
If device_add() fails in snic_tgt_create(), tgt will be freed, but
tgt->list will not be removed from snic->disc.tgt_list, then list traversal
may cause UAF.
Remove from snic->disc.tgt_list before free().

Summary
In the Linux kernel, the following vulnerability has been resolved:
l2tp: Avoid possible recursive deadlock in l2tp_tunnel_register()
When a file descriptor of pppol2tp socket is passed as file descriptor
of UDP socket, a recursive deadlock occurs in l2tp_tunnel_register().
This situation is reproduced by the following program:
int main(void)
{
int sock;
struct sockaddr_pppol2tp addr;
sock = socket(AF_PPPOX, SOCK_DGRAM, PX_PROTO_OL2TP);
if (sock < 0) {
perror("socket");
return 1;
}
addr.sa_family = AF_PPPOX;
addr.sa_protocol = PX_PROTO_OL2TP;
addr.pppol2tp.pid = 0;
addr.pppol2tp.fd = sock;
addr.pppol2tp.addr.sin_family = PF_INET;
addr.pppol2tp.addr.sin_port = htons(0);
addr.pppol2tp.addr.sin_addr.s_addr = inet_addr("192.168.0.1");
addr.pppol2tp.s_tunnel = 1;
addr.pppol2tp.s_session = 0;
addr.pppol2tp.d_tunnel = 0;
addr.pppol2tp.d_session = 0;
if (connect(sock, (const struct sockaddr *)&addr, sizeof(addr)) < 0) {
perror("connect");
return 1;
}
return 0;
}
This program causes the following lockdep warning:

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm: don't attempt to queue IO under RCU protection
dm looks up the table for IO based on the request type, with an
assumption that if the request is marked REQ_NOWAIT, it's fine to
attempt to submit that IO while under RCU read lock protection. This
is not OK, as REQ_NOWAIT just means that we should not be sleeping
waiting on other IO, it does not mean that we can't potentially
schedule.
A simple test case demonstrates this quite nicely:
int main(int argc, char *argv[])
{
struct iovec iov;
int fd;
fd = open("/dev/dm-0", O_RDONLY | O_DIRECT);
posix_memalign(&iov.iov_base, 4096, 4096);
iov.iov_len = 4096;
preadv2(fd, &iov, 1, 0, RWF_NOWAIT);
return 0;
}
which will instantly spew:
BUG: sleeping function called from invalid context at include/linux/sched/mm.h:306
in_atomic(): 0, irqs_disabled(): 0, non_block: 0, pid: 5580, name: dm-nowait

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtl8xxxu: Fix memory leaks with RTL8723BU, RTL8192EU
The wifi + bluetooth combo chip RTL8723BU can leak memory (especially?)
when it's connected to a bluetooth audio device. The busy bluetooth
traffic generates lots of C2H (card to host) messages, which are not
freed correctly.
To fix this, move the dev_kfree_skb() call in rtl8xxxu_c2hcmd_callback()
inside the loop where skb_dequeue() is called.
The RTL8192EU leaks memory because the C2H messages are added to the
queue and left there forever. (This was fine in the past because it
probably wasn't sending any C2H messages until commit e542e66b7c2e
("wifi: rtl8xxxu: gen2: Turn on the rate control"). Since that commit
it sends a C2H message when the TX rate changes.)
To fix this, delete the check for rf_paths > 1 and the goto. Let the
function process the C2H messages from RTL8192EU like the ones from
the other chips.
Theoretically the RTL8188FU could also leak like RTL8723BU, but it
most likely doesn't send C2H messages frequently enough.
This change was tested with RTL8723BU by Erhard F. I tested it with
RTL8188FU and RTL8192EU.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: avoid uninit memory read in ath9k_htc_rx_msg()
syzbot is reporting uninit value at ath9k_htc_rx_msg() [1], for
ioctl(USB_RAW_IOCTL_EP_WRITE) can call ath9k_hif_usb_rx_stream() with
pkt_len = 0 but ath9k_hif_usb_rx_stream() uses
__dev_alloc_skb(pkt_len + 32, GFP_ATOMIC) based on an assumption that
pkt_len is valid. As a result, ath9k_hif_usb_rx_stream() allocates skb
with uninitialized memory and ath9k_htc_rx_msg() is reading from
uninitialized memory.
Since bytes accessed by ath9k_htc_rx_msg() is not known until
ath9k_htc_rx_msg() is called, it would be difficult to check minimal valid
pkt_len at "if (pkt_len > 2 * MAX_RX_BUF_SIZE) {" line in
ath9k_hif_usb_rx_stream().
We have two choices. One is to workaround by adding __GFP_ZERO so that
ath9k_htc_rx_msg() sees 0 if pkt_len is invalid. The other is to let
ath9k_htc_rx_msg() validate pkt_len before accessing. This patch chose
the latter.
Note that I'm not sure threshold condition is correct, for I can't find
details on possible packet length used by this protocol.

No local access or network adjacency is required.\nAC:H - Exploitation requires statistically extracting nanosecond-scale timing deltas from the early-exit `memcmp` across network jitter and target CPU load, and on 64-bit architectures with `HAVE_EFFICIENT_UNALIGNED_ACCESS` the loop leaks only 8-byte-granular prefixes \u2014 conditions the attacker cannot influence. The bad-signature path is a silent `sctp_sf_pdiscard()`, so no direct request/response oracle exists.\nPR:N - The COOKIE ECHO path is reached pre-authentication on any listening SCTP socket, with the attacker supplying both the cookie contents and the matching verification tag, so no credentials or prior association state are needed. Cookie HMAC signing is enabled by default via `CONFIG_SCTP_DEFAULT_COOKIE_HMAC_MD5`.\nUI:N - The vulnerable comparisons execute automatically in the SCTP receive path for every COOKIE ECHO or AUTH chunk that reaches a listening endpoint or established association. No action by any local user or administrator is involved.\nS:U - The forged-MAC consequences \u2014 spoofed association establishment, out-of-bounds reads, and softirq hangs \u2014 all occur inside the kernel of the targeted host. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - A forged cookie MAC yields a fully attacker-controlled `struct sctp_cookie` whose unvalidated `raw_addr_list_len` drives an unbounded walk in `sctp_raw_to_bind_addrs()`, reading far past the skb. A forged SCTP-AUTH HMAC additionally allows ASCONF Add-IP injection to redirect an established association\u0027s data stream to the attacker.\nI:H - Recovering the MAC constitutes a complete bypass of SCTP\u0027s state-cookie and SCTP-AUTH authentication, letting an off-path attacker forge cookies to establish spoofed associations and inject arbitrary authenticated chunks into existing ones. The attacker-controlled cookie is copied wholesale into the new association via `memcpy(\u0026retval-\u003ec, bear_cookie, ...)` and fed to `sctp_process_init()`.\nA:H - With the cookie MAC forged, `sctp_raw_to_bind_addrs()` at this commit has no bounds checks \u2014 a zero-length address parameter makes `addrs_len -= len` never progress, producing an infinite loop in softirq context, while an oversized length causes an OOB read that can oops the kernel. Forged AUTH chunks also permit tearing down established associations."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: use smc_lgr_list.lock to protect smc_lgr_list.list iterate in smcr_port_add
While doing smcr_port_add, there maybe linkgroup add into or delete
from smc_lgr_list.list at the same time, which may result kernel crash.
So, use smc_lgr_list.lock to protect smc_lgr_list.list iterate in
smcr_port_add.
The crash calltrace show below:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda/ca0132: fixup buffer overrun at tuning_ctl_set()
tuning_ctl_set() might have buffer overrun at (X) if it didn't break
from loop by matching (A).
static int tuning_ctl_set(...)
{
for (i = 0; i < TUNING_CTLS_COUNT; i++)
(A) if (nid == ca0132_tuning_ctls[i].nid)
break;
snd_hda_power_up(...);
(X) dspio_set_param(..., ca0132_tuning_ctls[i].mid, ...);
snd_hda_power_down(...); ^
return 1;
}
We will get below error by cppcheck
sound/pci/hda/patch_ca0132.c:4229:2: note: After for loop, i has value 12
for (i = 0; i < TUNING_CTLS_COUNT; i++)
^
sound/pci/hda/patch_ca0132.c:4234:43: note: Array index out of bounds
dspio_set_param(codec, ca0132_tuning_ctls[i].mid, 0x20,
^
This patch cares non match case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: ocelot: call dsa_tag_8021q_unregister() under rtnl_lock() on driver remove
When the tagging protocol in current use is "ocelot-8021q" and we unbind
the driver, we see this splat:

This was somewhat not so easy to spot, because "ocelot-8021q" is not the
default tagging protocol, and thus, not everyone who tests the unbinding
path may have switched to it beforehand. The default
felix_tag_npi_teardown() does not require rtnl_lock() to be held.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: mediatek: vcodec: fix resource leaks in vdec_msg_queue_init()
If we encounter any error in the vdec_msg_queue_init() then we need
to set "msg_queue->wdma_addr.size = 0;". Normally, this is done
inside the vdec_msg_queue_deinit() function. However, if the
first call to allocate &msg_queue->wdma_addr fails, then the
vdec_msg_queue_deinit() function is a no-op. For that situation, just
set the size to zero explicitly and return.
There were two other error paths which did not clean up before returning.
Change those error paths to goto mem_alloc_err.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gtp: Fix use-after-free in __gtp_encap_destroy().
syzkaller reported use-after-free in __gtp_encap_destroy(). [0]
It shows the same process freed sk and touched it illegally.
Commit e198987e7dd7 ("gtp: fix suspicious RCU usage") added lock_sock()
and release_sock() in __gtp_encap_destroy() to protect sk->sk_user_data,
but release_sock() is called after sock_put() releases the last refcnt.

"value": "AV:L - The vulnerability is reached through local syscalls only \u2014 `socket()`/`setsockopt(SOL_UDP, UDP_ENCAP)` on a UDP socket plus `RTM_NEWLINK`/`RTM_DELLINK` messages on an AF_NETLINK socket. No network packet reaches the vulnerable code.\nAC:L - The trigger is a fully deterministic, race-free sequence: attaching a UDP socket to a gtp link, zeroing `up-\u003eencap_type` via unprivileged `setsockopt(UDP_ENCAP, 0)` so `udpv6_destroy_sock()` skips the `encap_destroy` callback, closing the fd, then deleting the link \u2014 guaranteeing GTP holds the last reference when `sock_put()` runs. The attacker also fully controls heap grooming for the reclaim.\nPR:L - The rtnetlink gates are `netlink_net_capable(skb, CAP_NET_ADMIN)` and `netlink_ns_capable(skb, net-\u003euser_ns, CAP_NET_ADMIN)`, which are user-namespace scoped, so any unprivileged local user obtains them via `unshare -Urn`; `gtp_net_ops` is a pernet subsys so gtp links are creatable in that netns, and `MODULE_ALIAS_RTNL_LINK(\"gtp\")` lets the same request autoload gtp.ko. The `UDP_ENCAP` setsockopt step requires no privileges at all.\nUI:N - The entire sequence is performed by the attacker\u0027s own process; no victim action, no administrator configuration, and no interaction with any other user is needed.\nS:U - The freed `struct sock` and the resulting corruption are both within the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or hypervisor boundary.\nC:H - The use-after-free on a 1344-byte UDPv6 `struct sock` lets an attacker who reclaims the object have the kernel read attacker-influenced pointers (`sk_prot`, `sk_backlog.head/tail`, `sk_lock.wq`) and dereference them, yielding kernel memory disclosure and full read primitives.\nI:H - `release_sock()` on the freed object performs an indirect call through `sk-\u003esk_prot-\u003erelease_cb` and, via `__release_sock()`, through `sk-\u003esk_backlog_rcv`, plus waitqueue list-pointer writes \u2014 giving control-flow hijack and arbitrary-write primitives once the slab object is reclaimed, i.e. local privilege escalation.\nA:H - Even without exploitation the bug is a guaranteed slab use-after-free \u2014 a spinlock cmpxchg and list operations on freed memory \u2014 reliably producing kernel oops, slab corruption, or hang, and it is repeatable at will by an unprivileged local user."

Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: omap_hsmmc: fix return value check of mmc_add_host()
mmc_add_host() may return error, if we ignore its return value,
it will lead two issues:
1. The memory that allocated in mmc_alloc_host() is leaked.
2. In the remove() path, mmc_remove_host() will be called to
delete device, but it's not added yet, it will lead a kernel
crash because of null-ptr-deref in device_del().
Fix this by checking the return value and goto error path wihch
will call mmc_free_host().

Any internet-facing host with an IPv6 TCP listener (or that merely replies with RST) exposes the vulnerable function to unauthenticated remote traffic.\nAC:H - The attacker freely supplies the transmit side of the race by sending TCP/SCTP traffic, but the `dst_dev_put()` side (netdev unregister/link-down, veth teardown, route-exception/pcpu-route destruction) is an operational event they cannot influence from the network, and escalating past a crash requires the freed `net_device`/`inet6_dev` slab object to be reallocated with attacker-useful content. This matches sibling CVE-2025-40158 and CVE-2025-40168 in the same dst_dev_rcu series.\nPR:N - SYNACK and RST generation happen with no credentials, no established session, and no local account on the target \u2014 the kernel transmits automatically on packet arrival. Even under a purely local framing, both halves of the race (IPv6 traffic plus veth create/delete and route flush) are available to any unprivileged user via `unshare -Urn`, so no real privilege is required either way.\nUI:N - Packet transmission occurs unconditionally in softirq or backlog-drain context when traffic arrives; no administrator or local user has to open, mount, configure, or click anything.\nS:U - The freed `net_device` and `inet6_dev` are kernel-internal objects and the resulting corruption stays entirely within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free read of `dev-\u003ehard_header_len`/`needed_headroom` via `LL_RESERVED_SPACE()`, of `idev-\u003estats.ipv6`, and of `out-\u003ename`/`out-\u003eifindex` inside the `NF_HOOK(NF_INET_LOCAL_OUT)` traversal; once the freed slab object is reallocated the attacker can steer header-expansion sizing and the recorded egress device, yielding kernel memory disclosure and misdirected packet leakage.\nI:H - `IP6_INC_STATS(net, idev, ...)` expands to `SNMP_INC_STATS64(idev-\u003estats.ipv6, field)`, performing a 64-bit increment through a per-CPU pointer loaded from freed memory \u2014 a write primitive after reallocation \u2014 and the stale `dev` propagates into `skb-\u003edev` and the netfilter hook state, giving control over structures used for further dispatch.\nA:H - Dereferencing a freed `inet6_dev`/`net_device` on the IPv6 transmit path reliably produces a KASAN slab-use-after-free splat, oops, or panic, and because the fault is in the core TCP/SCTP egress path it takes down the entire host."

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: sf-pdma: pdma_desc memory leak fix
Commit b2cc5c465c2c ("dmaengine: sf-pdma: Add multithread support for a
DMA channel") changed sf_pdma_prep_dma_memcpy() to unconditionally
allocate a new sf_pdma_desc each time it is called.
The driver previously recycled descs, by checking the in_use flag, only
allocating additional descs if the existing one was in use. This logic
was removed in commit b2cc5c465c2c ("dmaengine: sf-pdma: Add multithread
support for a DMA channel"), but sf_pdma_free_desc() was not changed to
handle the new behaviour.
As a result, each time sf_pdma_prep_dma_memcpy() is called, the previous
descriptor is leaked, over time leading to memory starvation:
unreferenced object 0xffffffe008447300 (size 192):
comm "irq/39-mchp_dsc", pid 343, jiffies 4294906910 (age 981.200s)
hex dump (first 32 bytes):

00 00 70 08 10 00 00 00 00 00 00 c0 00 00 00 00 ..p.............
backtrace:
[<00000000064a04f4>] kmemleak_alloc+0x1e/0x28
[<00000000018927a7>] kmem_cache_alloc+0x11e/0x178
[<000000002aea8d16>] sf_pdma_prep_dma_memcpy+0x40/0x112
Add the missing kfree() to sf_pdma_free_desc(), and remove the redundant
in_use flag.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Disable preemption in bpf_perf_event_output
The nesting protection in bpf_perf_event_output relies on disabled
preemption, which is guaranteed for kprobes and tracepoints.
However bpf_perf_event_output can be also called from uprobes context
through bpf_prog_run_array_sleepable function which disables migration,
but keeps preemption enabled.
This can cause task to be preempted by another one inside the nesting
protection and lead eventually to two tasks using same perf_sample_data
buffer and cause crashes like:
kernel tried to execute NX-protected page - exploit attempt? (uid: 0)
BUG: unable to handle page fault for address: ffffffff82be3eea

Fixing this by disabling preemption in bpf_perf_event_output.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fuse: fix livelock in synchronous file put from fuseblk workers
I observed a hang when running generic/323 against a fuseblk server.
This test opens a file, initiates a lot of AIO writes to that file
descriptor, and closes the file descriptor before the writes complete.
Unsurprisingly, the AIO exerciser threads are mostly stuck waiting for
responses from the fuseblk server:
# cat /proc/372265/task/372313/stack
[<0>] request_wait_answer+0x1fe/0x2a0 [fuse]
[<0>] __fuse_simple_request+0xd3/0x2b0 [fuse]
[<0>] fuse_do_getattr+0xfc/0x1f0 [fuse]
[<0>] fuse_file_read_iter+0xbe/0x1c0 [fuse]
[<0>] aio_read+0x130/0x1e0
[<0>] io_submit_one+0x542/0x860
[<0>] __x64_sys_io_submit+0x98/0x1a0
[<0>] do_syscall_64+0x37/0xf0
[<0>] entry_SYSCALL_64_after_hwframe+0x4b/0x53
But the /weird/ part is that the fuseblk server threads are waiting for
responses from itself:
# cat /proc/372210/task/372232/stack
[<0>] request_wait_answer+0x1fe/0x2a0 [fuse]
[<0>] __fuse_simple_request+0xd3/0x2b0 [fuse]
[<0>] fuse_file_put+0x9a/0xd0 [fuse]
[<0>] fuse_release+0x36/0x50 [fuse]
[<0>] __fput+0xec/0x2b0
[<0>] task_work_run+0x55/0x90
[<0>] syscall_exit_to_user_mode+0xe9/0x100
[<0>] do_syscall_64+0x43/0xf0
[<0>] entry_SYSCALL_64_after_hwframe+0x4b/0x53
The fuseblk server is fuse2fs so there's nothing all that exciting in
the server itself. So why is the fuse server calling fuse_file_put?
The commit message for the fstest sheds some light on that:
"By closing the file descriptor before calling io_destroy, you pretty
much guarantee that the last put on the ioctx will be done in interrupt
context (during I/O completion).
Aha. AIO fgets a new struct file from the fd when it queues the ioctx.
The completion of the FUSE_WRITE command from userspace causes the fuse
server to call the AIO completion function. The completion puts the
struct file, queuing a delayed fput to the fuse server task. When the
fuse server task returns to userspace, it has to run the delayed fput,
which in the case of a fuseblk server, it does synchronously.
Sending the FUSE_RELEASE command sychronously from fuse server threads
is a bad idea because a client program can initiate enough simultaneous
AIOs such that all the fuse server threads end up in delayed_fput, and
now there aren't any threads left to handle the queued fuse commands.
Fix this by only using asynchronous fputs when closing files, and leave
a comment explaining why.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mtd: spi-nor: Fix shift-out-of-bounds in spi_nor_set_erase_type
spi_nor_set_erase_type() was used either to set or to mask out an erase
type. When we used it to mask out an erase type a shift-out-of-bounds
was hit:
UBSAN: shift-out-of-bounds in drivers/mtd/spi-nor/core.c:2237:24
shift exponent 4294967295 is too large for 32-bit type 'int'
The setting of the size_{shift, mask} and of the opcode are unnecessary
when the erase size is zero, as throughout the code just the erase size
is considered to determine whether an erase type is supported or not.
Setting the opcode to 0xFF was wrong too as nobody guarantees that 0xFF
is an unused opcode. Thus when masking out an erase type, just set the
erase size to zero. This will fix the shift-out-of-bounds.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/sched: Fix deadlock in drm_sched_entity_kill_jobs_cb
The Mesa issue referenced below pointed out a possible deadlock:
[ 1231.611031] Possible interrupt unsafe locking scenario:
[ 1231.611033] CPU0 CPU1
[ 1231.611034] ---- ----
[ 1231.611035] lock(&xa->xa_lock#17);
[ 1231.611038] local_irq_disable();
[ 1231.611039] lock(&fence->lock);
[ 1231.611041] lock(&xa->xa_lock#17);
[ 1231.611044] <Interrupt>
[ 1231.611045] lock(&fence->lock);
[ 1231.611047]
*** DEADLOCK ***
In this example, CPU0 would be any function accessing job->dependencies
through the xa_* functions that don't disable interrupts (eg:
drm_sched_job_add_dependency(), drm_sched_entity_kill_jobs_cb()).
CPU1 is executing drm_sched_entity_kill_jobs_cb() as a fence signalling
callback so in an interrupt context. It will deadlock when trying to
grab the xa_lock which is already held by CPU0.
Replacing all xa_* usage by their xa_*_irq counterparts would fix
this issue, but Christian pointed out another issue: dma_fence_signal
takes fence.lock and so does dma_fence_add_callback.
dma_fence_signal() // locks f1.lock
-> drm_sched_entity_kill_jobs_cb()
-> foreach dependencies
-> dma_fence_add_callback() // locks f2.lock
This will deadlock if f1 and f2 share the same spinlock.
To fix both issues, the code iterating on dependencies and re-arming them
is moved out to drm_sched_entity_kill_jobs_work().

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix NULL-ptr-deref in rxe_qp_do_cleanup() when socket create failed
There is a null-ptr-deref when mount.cifs over rdma:
BUG: KASAN: null-ptr-deref in rxe_qp_do_cleanup+0x2f3/0x360 [rdma_rxe]

Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc3

The root cause of the issue is the socket create failed in
rxe_qp_init_req().
So move the reset rxe_qp_do_cleanup() after the NULL ptr check.

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: zynqmp: Fix stack-out-of-bounds in strncpy`
"BUG: KASAN: stack-out-of-bounds in strncpy+0x30/0x68"
Linux-ATF interface is using 16 bytes of SMC payload. In case clock name is
longer than 15 bytes, string terminated NULL character will not be received
by Linux. Add explicit NULL character at last byte to fix issues when clock
name is longer.
This fixes below bug reported by KASAN:

Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring: fix incorrect io_kiocb reference in io_link_skb
In io_link_skb function, there is a bug where prev_notif is incorrectly
assigned using 'nd' instead of 'prev_nd'. This causes the context
validation check to compare the current notification with itself instead
of comparing it with the previous notification.
Fix by using the correct prev_nd parameter when obtaining prev_notif.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btusb: reorder cleanup in btusb_disconnect to avoid UAF
There is a KASAN: slab-use-after-free read in btusb_disconnect().
Calling "usb_driver_release_interface(&btusb_driver, data->intf)" will
free the btusb data associated with the interface. The same data is
then used later in the function, hence the UAF.
Fix by moving the accesses to btusb data to before the data is free'd.

This matches the scoring of CVE-2025-71082, the general fix for the identical `devm_kzalloc` lifetime root cause.\nAC:L - The attacker chooses exactly which interface is released and when, so the free-then-use sequence executes deterministically every time \u2014 no race or memory-layout condition outside their control is involved.\nPR:L - The attacker needs an unprivileged local account holding a writable handle on the device\u0027s usbfs node, routinely granted via plugdev/uaccess ACLs or USB passthrough into a container; no CAP_SYS_ADMIN or init-namespace root is required.\nUI:N - The ioctl/unbind is issued entirely by the attacker\u0027s own process against an already-enumerated dongle; no victim action is needed.\nS:U - The corruption and its consequences are confined to the kernel\u0027s own security authority \u2014 there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - Per kernel scoring guidance a use-after-free is High; reclaiming the freed `btusb_data` slot lets the attacker steer `data-\u003eudev` and `data-\u003ereset_gpio` into `device_init_wakeup()`/`gpiod_put()`, yielding a controlled-pointer read primitive usable for kernel memory disclosure.\nI:H - The stale `data-\u003eudev` is dereferenced and written through by `device_init_wakeup()`, and `data-\u003ereset_gpio` is passed to `gpiod_put()`/`gpiod_free()`, giving heap-spray-backed write and free primitives suitable for control-flow hijack.\nA:H - Even unweaponized, the slab-use-after-free reads a poisoned or reallocated pointer and dereferences it, producing the KASAN-confirmed oops/panic reported by syzbot."

Summary
In the Linux kernel, the following vulnerability has been resolved:
loop: loop_set_status_from_info() check before assignment
In loop_set_status_from_info(), lo->lo_offset and lo->lo_sizelimit should
be checked before reassignment, because if an overflow error occurs, the
original correct value will be changed to the wrong value, and it will not
be changed back.
More, the original patch did not solve the problem, the value was set and
ioctl returned an error, but the subsequent io used the value in the loop
driver, which still caused an alarm:
loop_handle_cmd
do_req_filebacked
loff_t pos = ((loff_t) blk_rq_pos(rq) << 9) + lo->lo_offset;
lo_rw_aio
cmd->iocb.ki_pos = pos

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: MGMT: Fix OOB access in parse_adv_monitor_pattern()
In the parse_adv_monitor_pattern() function, the value of
the 'length' variable is currently limited to HCI_MAX_EXT_AD_LENGTH(251).
The size of the 'value' array in the mgmt_adv_pattern structure is 31.
If the value of 'pattern[i].length' is set in the user space
and exceeds 31, the 'patterns[i].value' array can be accessed
out of bound when copied.
Increasing the size of the 'value' array in
the 'mgmt_adv_pattern' structure will break the userspace.
Considering this, and to avoid OOB access revert the limits for 'offset'
and 'length' back to the value of HCI_MAX_AD_LENGTH.
Found by InfoTeCS on behalf of Linux Verification Center
(linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
misc: fastrpc: Fix dma_buf object leak in fastrpc_map_lookup
In fastrpc_map_lookup, dma_buf_get is called to obtain a reference to
the dma_buf for comparison purposes. However, this reference is never
released when the function returns, leading to a dma_buf memory leak.
Fix this by adding dma_buf_put before returning from the function,
ensuring that the temporarily acquired reference is properly released
regardless of whether a matching map is found.
Rule: add

In the Linux kernel, the following vulnerability has been resolved:
vduse: fix NULL pointer dereference
vduse_vdpa_set_vq_affinity callback can be called
with NULL value as cpu_mask when deleting the vduse
device.
This patch resets virtqueue's IRQ affinity mask value
to set all CPUs instead of dereferencing NULL cpu_mask.

Summary
In the Linux kernel, the following vulnerability has been resolved:
regulator: stm32-pwr: fix of_iomap leak
Smatch reports:
drivers/regulator/stm32-pwr.c:166 stm32_pwr_regulator_probe() warn:
'base' from of_iomap() not released on lines: 151,166.
In stm32_pwr_regulator_probe(), base is not released
when devm_kzalloc() fails to allocate memory or
devm_regulator_register() fails to register a new regulator device,
which may cause a leak.
To fix this issue, replace of_iomap() with
devm_platform_ioremap_resource(). devm_platform_ioremap_resource()
is a specialized function for platform devices.
It allows 'base' to be automatically released whether the probe
function succeeds or fails.
Besides, use IS_ERR(base) instead of !base
as the return value of devm_platform_ioremap_resource()
can either be a pointer to the remapped memory or
an ERR_PTR() encoded error code if the operation fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: fix underflow in chain reference counter
Set element addition error path decrements reference counter on chains
twice: once on element release and again via nft_data_release().
Then, d6b478666ffa ("netfilter: nf_tables: fix underflow in object
reference counter") incorrectly fixed this by removing the stateful
object reference count decrement.
Restore the stateful object decrement as in b91d90368837 ("netfilter:
nf_tables: fix leaking object reference count") and let
nft_data_release() decrement the chain reference counter, so this is
done only once.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mtdchar: fix integer overflow in read/write ioctls
The "req.start" and "req.len" variables are u64 values that come from the
user at the start of the function. We mask away the high 32 bits of
"req.len" so that's capped at U32_MAX but the "req.start" variable can go
up to U64_MAX which means that the addition can still integer overflow.
Use check_add_overflow() to fix this bug.

"value": "AV:N - ib_isert is the in-kernel iSER (iSCSI over RDMA) target; the leak is driven entirely by an RDMA-CM connect/teardown from a remote initiator over RoCEv2 (routable UDP/IP), iWARP (TCP), or soft-RoCE/siw. This is a network-facing storage service equivalent to nvmet-tcp or nfsd.\nAC:L - The missed kref_put is deterministic \u2014 every single connection teardown leaks the isert_conn, its QP, its CQ reservation and the PD reference, with no race, timing window, or memory-layout dependency. The attacker just loops connect-then-abort.\nPR:N - isert_accept_np() binds the connection before iSCSI login, and the iSCSI login-failure path iscsi_target_login_sess_out() calls isert_wait_conn()/isert_free_conn() directly, so the leak is triggered entirely pre-authentication. The attacker holds no credentials on the target.\nUI:N - The target\u0027s np login thread accepts and tears down incoming iSER connections autonomously; no action by any local user or administrator is needed.\nS:U - The leaked memory, QPs, CQs and PD all belong to the kernel that is running the vulnerable code; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - The defect is a reference-count leak \u2014 no out-of-bounds read, no stale-pointer dereference, and no uninitialized data is returned on any attacker-reachable path, so no information is disclosed.\nI:N - Nothing is written out of bounds and no control-flow structure is corrupted on the reachable path; the only effect is that objects which should have been destroyed remain allocated.\nA:H - An unauthenticated remote peer can leak an isert_conn plus a full QP, a 264-cqe CQ pool reservation and DMA-mapped buffers on every connection attempt, exhausting kernel memory and finite HCA resources until all RDMA on the host fails. The same defect also produces the reported WARN_ON splat in ib_cq_pool_cleanup and leaves the RDMA_CM_EVENT_DEVICE_REMOVAL handler waiting forever on a ISER_CONN_DOWN transition that can never occur, hanging device removal."

The NFSv4.1 `nfserr_op_not_in_session` path (nfs4proc.c:3087-3093) fires before session establishment, making this a pre-authentication code path.\nUI:N - The attacker sends the malformed COMPOUND directly to the NFS server; no administrator or client-side action is required at exploitation time.\nS:U - The NULL dereference oops occurs in the nfsd kthread within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - `nfsd4_decode_read()` memsets the whole `struct nfsd4_read`, so `rd_rqstp`/`rd_fhp` are guaranteed NULL rather than stale pointers \u2014 the fault occurs on the first access and no data is read into the trace buffer or otherwise disclosed.\nI:N - The tracepoint\u0027s `TP_fast_assign` performs only loads from the NULL pointers; there is no out-of-bounds or use-after-free write and no control-flow hijack primitive.\nA:H - A NULL pointer dereference oops kills the nfsd kernel thread mid-compound (leaking the unreleased current_fh/save_fh references), and the request can be replayed to exhaust every nfsd thread; with panic_on_oops set it is an immediate kernel panic."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix use-after-free in ext4_orphan_cleanup
I caught a issue as follows:

[...]
==================================================================
Above issue may happen as follows:
-------------------------------------
ext4_fill_super
ext4_orphan_cleanup
--- loop1: assume last_orphan is 12 ---
list_add(&EXT4_I(inode)->i_orphan, &EXT4_SB(sb)->s_orphan)
ext4_truncate --> return 0
ext4_inode_attach_jinode --> return -ENOMEM
iput(inode) --> free inode<12>
--- loop2: last_orphan is still 12 ---
list_add(&EXT4_I(inode)->i_orphan, &EXT4_SB(sb)->s_orphan);
// use inode<12> and trigger UAF
To solve this issue, we need to propagate the return value of
ext4_inode_attach_jinode() appropriately.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vmci_host: fix a race condition in vmci_host_poll() causing GPF
During fuzzing, a general protection fault is observed in
vmci_host_poll().
general protection fault, probably for non-canonical address 0xdffffc0000000019: 0000 [#1] PREEMPT SMP KASAN
KASAN: null-ptr-deref in range [0x00000000000000c8-0x00000000000000cf]
RIP: 0010:__lock_acquire+0xf3/0x5e00 kernel/locking/lockdep.c:4926

Example thread interleaving that causes the general protection fault
is as follows:
CPU1 (vmci_host_poll) CPU2 (vmci_host_do_init_context)
----- -----
// Read uninitialized context
context = vmci_host_dev->context;
// Initialize context
vmci_host_dev->context = vmci_ctx_create();
vmci_host_dev->ct_type = VMCIOBJ_CONTEXT;
if (vmci_host_dev->ct_type == VMCIOBJ_CONTEXT) {
// Dereferencing the wrong pointer
poll_wait(..., &context->host_context);
}
In this scenario, vmci_host_poll() reads vmci_host_dev->context first,
and then reads vmci_host_dev->ct_type to check that
vmci_host_dev->context is initialized. However, since these two reads
are not atomically executed, there is a chance of a race condition as
described above.
To fix this race condition, read vmci_host_dev->context after checking
the value of vmci_host_dev->ct_type so that vmci_host_poll() always
reads an initialized context.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm: verity-loadpin: Only trust verity targets with enforcement
Verity targets can be configured to ignore corrupted data blocks.
LoadPin must only trust verity targets that are configured to
perform some kind of enforcement when data corruption is detected,
like returning an error, restarting the system or triggering a
panic.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sctp: avoid NULL dereference when chunk data buffer is missing
chunk->skb pointer is dereferenced in the if-block where it's supposed
to be NULL only.
chunk->skb can only be NULL if chunk->head_skb is not. Check for frag_list
instead and do it just before replacing chunk->skb. We're sure that
otherwise chunk->skb is non-NULL because of outer if() condition.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_event: validate skb length for unknown CC opcode
In hci_cmd_complete_evt(), if the command complete event has an unknown
opcode, we assume the first byte of the remaining skb->data contains the
return status. However, parameter data has previously been pulled in
hci_event_func(), which may leave the skb empty. If so, using skb->data[0]
for the return status uses un-init memory.
The fix is to check skb->len before using skb->data.

No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:L - One byte of stale, uninitialized kernel heap memory is read and used as the HCI status, propagating to userspace only through lossy mappings (bt_to_errno() in __hci_cmd_sync_sk(), mgmt_status() in the mgmt path). This is a strictly bounded, low-fidelity disclosure rather than an arbitrary read.\nI:L - The garbage byte becomes the authoritative completion status for a pending HCI command, so a failing vendor command can be recorded as successful (or vice versa), corrupting hci_cmd_sync/mgmt state and device configuration decisions. The attacker modifies kernel state but has no control over the resulting value.\nA:H - Bogus command-completion status corrupts the HCI command state machine and can wedge or bring up the Bluetooth stack in an inconsistent state, and the access is an uninitialized-memory read that aborts the kernel under KMSAN/hardened configurations. The condition is remotely repeatable at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
regulator: core: fix resource leak in regulator_register()
I got some resource leak reports while doing fault injection test:
OF: ERROR: memory leak, expected refcount 1 instead of 100,
of_node_get()/of_node_put() unbalanced - destroy cset entry:

After calling regulator_resolve_supply(), the 'rdev->supply' is set
by set_supply(), after this set, in the error path, the resources
need be released, so call regulator_put() to avoid the leaks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Use correct encap attribute during invalidation
With introduction of post action infrastructure most of the users of encap
attribute had been modified in order to obtain the correct attribute by
calling mlx5e_tc_get_encap_attr() helper instead of assuming encap action
is always on default attribute. However, the cited commit didn't modify
mlx5e_invalidate_encap() which prevents it from destroying correct modify
header action which leads to a warning [0]. Fix the issue by using correct
attribute.

The only remaining gate on the 2 GiB AUX mapping is RLIMIT_MEMLOCK \u2014 a resource limit, not a privilege \u2014 which is routinely unlimited on the HPC/GPU/RDMA arm64 servers where SPE hardware exists, and is skipped entirely when perf_event_paranoid=-1.\nUI:N - The attacker profiles their own process and generates the trace data themselves; no victim action of any kind is involved.\nS:U - The out-of-bounds writes land in the kernel\u0027s own vmalloc region, within the same security authority as the vulnerable driver. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - PMBPTR_EL1 is programmed with buf-\u003ebase plus an unbounded offset, so the SPE hardware writes profiling records containing kernel/user addresses and data values into arbitrary kernel memory, and the corrupted size passed to perf_aux_output_end() exposes ring-buffer contents at bogus offsets to the userspace mmap. Out-of-bounds memory corruption of this scope is readily leveraged for information disclosure.\nI:H - arm_spe_pmu_pad_buf() memsets an attacker-influenced length starting at buf-\u003ebase + head, far past the end of the 2 GiB vmap region, and the SPE hardware independently writes trace records out of bounds. On arm64 the surrounding vmalloc space contains VMAP_STACKs, module text and BPF JIT images, making this an out-of-bounds write usable for control-flow hijacking.\nA:H - The runaway offset overwhelmingly lands on unmapped vmalloc addresses or vmap guard pages, faulting in kernel context, and the hardware buffer writes raise SPE external aborts that the driver treats as fatal \u2014 either way an oops or panic."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix NULL pointer dereference in VRAM logic for APU devices
Previously, APU platforms (and other scenarios with uninitialized VRAM managers)
triggered a NULL pointer dereference in `ttm_resource_manager_usage()`. The root
cause is not that the `struct ttm_resource_manager *man` pointer itself is NULL,
but that `man->bdev` (the backing device pointer within the manager) remains
uninitialized (NULL) on APUs—since APUs lack dedicated VRAM and do not fully
set up VRAM manager structures. When `ttm_resource_manager_usage()` attempts to
acquire `man->bdev->lru_lock`, it dereferences the NULL `man->bdev`, leading to
a kernel OOPS.
1. **amdgpu_cs.c**: Extend the existing bandwidth control check in
`amdgpu_cs_get_threshold_for_moves()` to include a check for
`ttm_resource_manager_used()`. If the manager is not used (uninitialized
`bdev`), return 0 for migration thresholds immediately—skipping VRAM-specific
logic that would trigger the NULL dereference.
2. **amdgpu_kms.c**: Update the `AMDGPU_INFO_VRAM_USAGE` ioctl and memory info
reporting to use a conditional: if the manager is used, return the real VRAM
usage; otherwise, return 0. This avoids accessing `man->bdev` when it is
NULL.
3. **amdgpu_virt.c**: Modify the vf2pf (virtual function to physical function)
data write path. Use `ttm_resource_manager_used()` to check validity: if the
manager is usable, calculate `fb_usage` from VRAM usage; otherwise, set
`fb_usage` to 0 (APUs have no discrete framebuffer to report).
This approach is more robust than APU-specific checks because it:
- Works for all scenarios where the VRAM manager is uninitialized (not just APUs),
- Aligns with TTM's design by using its native helper function,
- Preserves correct behavior for discrete GPUs (which have fully initialized
`man->bdev` and pass the `ttm_resource_manager_used()` check).
v4: use ttm_resource_manager_used(&adev->mman.vram_mgr.manager) instead of checking the adev->gmc.is_app_apu flag (Christian)

If the manager is not used (uninitialized\n `bdev`), return 0 for migration thresholds immediately\u2014skipping VRAM-specific\n logic that would trigger the NULL dereference.\n\n2. **amdgpu_kms.c**: Update the `AMDGPU_INFO_VRAM_USAGE` ioctl and memory info\n reporting to use a conditional: if the manager is used, return the real VRAM\n usage; otherwise, return 0. This avoids accessing `man-\u003ebdev` when it is\n NULL.\n\n3. **amdgpu_virt.c**: Modify the vf2pf (virtual function to physical function)\n data write path. Use `ttm_resource_manager_used()` to check validity: if the\n manager is usable, calculate `fb_usage` from VRAM usage; otherwise, set\n `fb_usage` to 0 (APUs have no discrete framebuffer to report).\n\nThis approach is more robust than APU-specific checks because it:\n- Works for all scenarios where the VRAM manager is uninitialized (not just APUs),\n- Aligns with TTM\u0027s design by using its native helper function,\n- Preserves correct behavior for discrete GPUs (which have fully initialized\n `man-\u003ebdev` and pass the `ttm_resource_manager_used()` check).\n\nv4: use ttm_resource_manager_used(\u0026adev-\u003emman.vram_mgr.manager) instead of checking the adev-\u003egmc.is_app_apu flag (Christian)"

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix type of second parameter in odn_edit_dpm_table() callback
With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),
indirect call targets are validated against the expected function
pointer prototype to make sure the call target is valid to help mitigate
ROP attacks. If they are not identical, there is a failure at run time,
which manifests as either a kernel panic or thread getting killed. A
proposed warning in clang aims to catch these at compile time, which
reveals:
drivers/gpu/drm/amd/amdgpu/../pm/swsmu/amdgpu_smu.c:3008:29: error: incompatible function pointer types initializing 'int (*)(void *, uint32_t, long *, uint32_t)' (aka 'int (*)(void *, unsigned int, long *, unsigned int)') with an expression of type 'int (void *, enum PP_OD_DPM_TABLE_COMMAND, long *, uint32_t)' (aka 'int (void *, enum PP_OD_DPM_TABLE_COMMAND, long *, unsigned int)') [-Werror,-Wincompatible-function-pointer-types-strict]
.odn_edit_dpm_table = smu_od_edit_dpm_table,
^~~~~~~~~~~~~~~~~~~~~
1 error generated.
There are only two implementations of ->odn_edit_dpm_table() in 'struct
amd_pm_funcs': smu_od_edit_dpm_table() and pp_odn_edit_dpm_table(). One
has a second parameter type of 'enum PP_OD_DPM_TABLE_COMMAND' and the
other uses 'u32'. Ultimately, smu_od_edit_dpm_table() calls
->od_edit_dpm_table() from 'struct pptable_funcs' and
pp_odn_edit_dpm_table() calls ->odn_edit_dpm_table() from 'struct
pp_hwmgr_func', which both have a second parameter type of 'enum
PP_OD_DPM_TABLE_COMMAND'.
Update the type parameter in both the prototype in 'struct amd_pm_funcs'
and pp_odn_edit_dpm_table() to 'enum PP_OD_DPM_TABLE_COMMAND', which
cleans up the warning.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ionic: remove WARN_ON to prevent panic_on_warn
Remove unnecessary early code development check and the WARN_ON
that it uses. The irq alloc and free paths have long been
cleaned up and this check shouldn't have stuck around so long.

Summary
In the Linux kernel, the following vulnerability has been resolved:
exfat: fix refcount leak in exfat_find
Fix refcount leaks in `exfat_find` related to `exfat_get_dentry_set`.
Function `exfat_get_dentry_set` would increase the reference counter of
`es->bh` on success. Therefore, `exfat_put_dentry_set` must be called
after `exfat_get_dentry_set` to ensure refcount consistency. This patch
relocate two checks to avoid possible leaks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/irdma: Fix data race on CQP request done
KCSAN detects a data race on cqp_request->request_done memory location
which is accessed locklessly in irdma_handle_cqp_op while being
updated in irdma_cqp_ce_handler.
Annotate lockless intent with READ_ONCE/WRITE_ONCE to avoid any
compiler optimizations like load fusing and/or KCSAN warning.

"value": "AV:N - CQP requests are issued directly from remote packet processing \u2014 `irdma_handle_syn_pkt()` creates an AH via CQP on an incoming TCP SYN to an iWARP listener, `irdma_add_conn_est_qh()` and the connection-teardown paths issue qhash CQP ops, and the IEQ path creates AHs from remote out-of-order MPA segments. A remote peer can therefore drive both CQP submission and completion traffic that races on the shared flag byte.\nAC:L - The attacker controls both sides of the race by driving an arbitrary rate of concurrent CQP operations (SYN/connection churn remotely, or concurrent verbs locally), which also exhausts the static request pool and forces the `kzalloc`/`dynamic` path. Non-atomic byte-wide RMW on a byte shared by three flags collides reliably at high operation rates.\nPR:N - The remote CM path that issues CQP requests runs during TCP SYN/MPA handling, before any MPA or application-level authentication. Even on the local path, `/dev/infiniband/uverbs*` is world-accessible (mode 0666) under standard rdma-core udev rules, so no privileges are needed.\nUI:N - The race is triggered purely by attacker-generated connection or verbs traffic against an already-configured RDMA device; no action by any local user or administrator is required.\nS:U - The corruption and its consequences are entirely within the kernel\u0027s own security authority \u2014 the irdma driver\u0027s request objects and the resources it manages. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - A stale `request_done` makes `irdma_handle_cqp_op()` report success while the hardware op is still in flight, so the request object is recycled while still referenced by `cqp-\u003escratch_array`, and CQ/QP/MR/DMA memory is freed while the device still owns it. The resulting use-after-free on `kzalloc`\u0027d requests gives an attacker control over freed-object contents and hence a read primitive.\nI:H - The same use-after-free leads to `cqp_request-\u003ecallback_fcn(cqp_request)` being invoked on a concurrently reused object and to refcount underflow/double free; a lost update on the adjacent `dynamic` bit additionally causes `kfree()` of a pointer inside the `kcalloc`\u0027d `cqp_requests` array (invalid free / slab corruption). Both are exploitable for kernel memory writes and control-flow hijack.\nA:H - A lost `request_done` drives the waiter to the CQP timeout, which calls `ice_rdma_request_reset(pf, IIDC_PFR)` \u2014 a full PF reset of the NIC \u2014 and latches `rf-\u003ereset`, failing all further CQP ops. A lost `waiting` bit skips `irdma_hw_modify_qp_callback()`, leaving `wait_event(iwqp-\u003emod_qp_waitq, \u2026)` (no timeout, uninterruptible) hung permanently, plus the UAF paths cause outright panics."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix stackmap overflow check in __bpf_get_stackid()
Syzkaller reported a KASAN slab-out-of-bounds write in __bpf_get_stackid()
when copying stack trace data. The issue occurs when the perf trace
contains more stack entries than the stack map bucket can hold,
leading to an out-of-bounds write in the bucket's data array.

Summary
In the Linux kernel, the following vulnerability has been resolved:
hfs: Fix OOB Write in hfs_asc2mac
Syzbot reported a OOB Write bug:
loop0: detected capacity change from 0 to 64
==================================================================
BUG: KASAN: slab-out-of-bounds in hfs_asc2mac+0x467/0x9a0
fs/hfs/trans.c:133
Write of size 1 at addr ffff88801848314e by task syz-executor391/3632
Call Trace:

path_openat+0x10e6/0x2df0 fs/namei.c:3710
do_filp_open+0x264/0x4f0 fs/namei.c:3740
If in->len is much larger than HFS_NAMELEN(31) which is the maximum
length of an HFS filename, a OOB write could occur in hfs_asc2mac(). In
that case, when the dst reaches the boundary, the srclen is still
greater than 0, which causes a OOB write.
Fix this by adding a check on dstlen in while() before writing to dst
address.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mtd: rawnand: cadence: fix DMA device NULL pointer dereference
The DMA device pointer `dma_dev` was being dereferenced before ensuring
that `cdns_ctrl->dmac` is properly initialized.
Move the assignment of `dma_dev` after successfully acquiring the DMA
channel to ensure the pointer is valid before use.

Failed attempts are harmless and can be retried indefinitely.\nPR:L - No capability check exists anywhere on the sock_diag/inet_diag dump path (the `net_admin` flag only selects optional attributes), and sctp_do_bind only needs CAP_NET_BIND_SERVICE for ports below 1024, which the attacker avoids. Any unprivileged local user with an SCTP socket can do this, without namespaces.\nUI:N - The attacker creates the SCTP endpoint, issues the diag dump, and grows the address list entirely on its own. No victim action of any kind is involved.\nS:U - The corruption is confined to kernel heap memory managed by the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The same TOCTOU in the shrink direction leaves the tail of the reserved INET_DIAG_LOCALS attribute uninitialized and copies that kernel heap data straight to userspace, and the heap overflow itself corrupts skb_shared_info (frag_list/destructor_arg), which is readily leveraged into arbitrary kernel memory disclosure.\nI:H - This is a heap out-of-bounds write with attacker-chosen length \u2014 a single bindx call can append ~8000 addresses, yielding up to ~1 MB written past the reserved region \u2014 and partially attacker-controlled content, smashing skb_shared_info and adjacent slab objects, which is a strong path to control-flow hijack and privilege escalation.\nA:H - Overwriting skb_shared_info and neighbouring allocations with sockaddr data reliably produces oopses and kernel panics on subsequent skb handling. Any unprivileged user can repeat the attack at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix warning in trace_buffered_event_disable()
Warning happened in trace_buffered_event_disable() at
WARN_ON_ONCE(!trace_buffered_event_ref)
Call Trace:
? __warn+0xa5/0x1b0
? trace_buffered_event_disable+0x189/0x1b0
__ftrace_event_enable_disable+0x19e/0x3e0
free_probe_data+0x3b/0xa0
unregister_ftrace_function_probe_func+0x6b8/0x800
event_enable_func+0x2f0/0x3d0
ftrace_process_regex.isra.0+0x12d/0x1b0
ftrace_filter_write+0xe6/0x140
vfs_write+0x1c9/0x6f0
[...]
The cause of the warning is in __ftrace_event_enable_disable(),
trace_buffered_event_enable() was called once while
trace_buffered_event_disable() was called twice.
Reproduction script show as below, for analysis, see the comments:
```
#!/bin/bash
cd /sys/kernel/tracing/
# 1. Register a 'disable_event' command, then:
# 1) SOFT_DISABLED_BIT was set;
# 2) trace_buffered_event_enable() was called first time;
echo 'cmdline_proc_show:disable_event:initcall:initcall_finish' > \
set_ftrace_filter
# 2. Enable the event registered, then:
# 1) SOFT_DISABLED_BIT was cleared;
# 2) trace_buffered_event_disable() was called first time;
echo 1 > events/initcall/initcall_finish/enable
# 3. Try to call into cmdline_proc_show(), then SOFT_DISABLED_BIT was
# set again!!!
cat /proc/cmdline
# 4. Unregister the 'disable_event' command, then:
# 1) SOFT_DISABLED_BIT was cleared again;
# 2) trace_buffered_event_disable() was called second time!!!
echo '!cmdline_proc_show:disable_event:initcall:initcall_finish' > \
set_ftrace_filter
```
To fix it, IIUC, we can change to call trace_buffered_event_enable() at
fist time soft-mode enabled, and call trace_buffered_event_disable() at
last time soft-mode disabled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: move init of percpu reply_cache_stats counters back to nfsd_init_net
Commit f5f9d4a314da ("nfsd: move reply cache initialization into nfsd
startup") moved the initialization of the reply cache into nfsd startup,
but didn't account for the stats counters, which can be accessed before
nfsd is ever started. The result can be a NULL pointer dereference when
someone accesses /proc/fs/nfsd/reply_cache_stats while nfsd is still
shut down.
This is a regression and a user-triggerable oops in the right situation:
- non-x86_64 arch
- /proc/fs/nfsd is mounted in the namespace
- nfsd is not started in the namespace
- unprivileged user calls "cat /proc/fs/nfsd/reply_cache_stats"
Although this is easy to trigger on some arches (like aarch64), on
x86_64, calling this_cpu_ptr(NULL) evidently returns a pointer to the
fixed_percpu_data. That struct looks just enough like a newly
initialized percpu var to allow nfsd_reply_cache_stats_show to access
it without Oopsing.
Move the initialization of the per-net+per-cpu reply-cache counters
back into nfsd_init_net, while leaving the rest of the reply cache
allocations to be done at nfsd startup time.
Kudos to Eirik who did most of the legwork to track this down.

Summary
In the Linux kernel, the following vulnerability has been resolved:
staging: vt6655: fix potential memory leak
In function device_init_td0_ring, memory is allocated for member
td_info of priv->apTD0Rings[i], with i increasing from 0. In case of
allocation failure, the memory is freed in reversed order, with i
decreasing to 0. However, the case i=0 is left out and thus memory is
leaked.
Modify the memory freeing loop to include the case i=0.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Finish converting the NFSv2 GETACL result encoder
The xdr_stream conversion inadvertently left some code that set the
page_len of the send buffer. The XDR stream encoders should handle
this automatically now.
This oversight adds garbage past the end of the Reply message.
Clients typically ignore the garbage, but NFSD does not need to send
it, as it leaks stale memory contents onto the wire.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: asymmetric_keys - prevent overflow in asymmetric_key_generate_id
Use check_add_overflow() to guard against potential integer overflows
when adding the binary blob lengths and the size of an asymmetric_key_id
structure and return ERR_PTR(-EOVERFLOW) accordingly. This prevents a
possible buffer overflow when copying data from potentially malicious
X.509 certificate fields that can be arbitrarily large, such as ASN.1
INTEGER serial numbers, issuer names, etc.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Sync pending IRQ work before freeing ring buffer
Fix a race where irq_work can be queued in bpf_ringbuf_commit()
but the ring buffer is freed before the work executes.
In the syzbot reproducer, a BPF program attached to sched_switch
triggers bpf_ringbuf_commit(), queuing an irq_work. If the ring buffer
is freed before this work executes, the irq_work thread may accesses
freed memory.
Calling `irq_work_sync(&rb->work)` ensures that all pending irq_work
complete before freeing the buffer.

There is no path for a remote peer to load BPF programs, so local system access is required.\nAC:L - The attacker controls both sides of the race: he triggers `bpf_ringbuf_commit()` on demand (loopback packet into his own socket filter, using `BPF_RB_FORCE_WAKEUP` to guarantee `irq_work_queue()` on every commit) and separately triggers the free by detaching and closing the map/prog fds, looping unboundedly. On PREEMPT_RT the work is deferred to the `irq_workd` kthread and on architectures without `arch_irq_work_has_interrupt()` to the next tick, widening the window to milliseconds; syzbot both reproduced the bug and confirmed the fix.\nPR:L - `BPF_MAP_TYPE_RINGBUF`/`USER_RINGBUF` are listed as unprivileged map types in `map_create()`, the ringbuf helpers sit above the `CAP_BPF` gate in `bpf_base_func_proto()`, `BPF_PROG_TYPE_SOCKET_FILTER` is exempt from the CAP_BPF prog-load check, and `SO_ATTACH_BPF` has no capability check \u2014 so an ordinary unprivileged user can build the entire chain on the upstream default `unprivileged_bpf_disabled=0`.\nUI:N - The attacker performs every step himself \u2014 map creation, program load, socket attach, packet injection, and fd close \u2014 with no victim action or cooperating process required.\nS:U - The use-after-free corrupts kernel memory and the per-CPU irq_work list within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `irq_work_single()` and `bpf_ringbuf_notify()`/`wake_up_all()` read `work-\u003enode.llist`, `work-\u003efunc`, `work-\u003eirqwait.task`, and the `waitq` list head out of freed memory, and the vmalloc VA range can be reclaimed with a large vmalloc-backed `BPF_MAP_TYPE_ARRAY` whose contents the attacker sets \u2014 turning the dangling traversal into an arbitrary kernel-memory read/disclosure primitive.\nI:H - The irq_work core performs `atomic_set()`/`atomic_cmpxchg()` writes into the freed object and an indirect call `work-\u003efunc(work)` on a pointer read from it, while `wake_up_all()` adds `list_del_init()` unlink writes and a second function-pointer call \u2014 after VA-range reclamation with controlled data this is a direct control-flow hijack and arbitrary-write path to privilege escalation.\nA:H - This is a use-after-free reported by syzbot as a KASAN splat; in the common case the irq_work dereferences an already-unmapped vmalloc address from hardirq or the `irq_workd` kthread, producing an unhandled page fault and kernel panic, and it can be re-triggered in a loop."

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: zoned: fix memory leak after finding block group with super blocks
At exclude_super_stripes(), if we happen to find a block group that has
super blocks mapped to it and we are on a zoned filesystem, we error out
as this is not supposed to happen, indicating either a bug or maybe some
memory corruption for example. However we are exiting the function without
freeing the memory allocated for the logical address of the super blocks.
Fix this by freeing the logical address.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix PCI device refcount leak in amdgpu_atrm_get_bios()
As comment of pci_get_class() says, it returns a pci_device with its
refcount increased and decreased the refcount for the input parameter
@from if it is not NULL.
If we break the loop in amdgpu_atrm_get_bios() with 'pdev' not NULL, we
need to call pci_dev_put() to decrease the refcount. Add the missing
pci_dev_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
smc: Fix use-after-free in tcp_write_timer_handler().
With Eric's ref tracker, syzbot finally found a repro for
use-after-free in tcp_write_timer_handler() by kernel TCP
sockets. [0]
If SMC creates a kernel socket in __smc_create(), the kernel
socket is supposed to be freed in smc_clcsock_release() by
calling sock_release() when we close() the parent SMC socket.
However, at the end of smc_clcsock_release(), the kernel
socket's sk_state might not be TCP_CLOSE. This means that
we have not called inet_csk_destroy_sock() in __tcp_close()
and have not stopped the TCP timers.
The kernel socket's TCP timers can be fired later, so we
need to hold a refcnt for net as we do for MPTCP subflows
in mptcp_subflow_create_socket().

In ar5523_probe(), ar5523_host_available() calls ar5523_cmd() as below
(there are other functions which finally call ar5523_cmd()):
ar5523_probe()
-> ar5523_host_available()
-> ar5523_cmd_read()
-> ar5523_cmd()
If ar5523_cmd() timed out, then ar5523_host_available() failed and
ar5523_probe() freed the device structure. So, ar5523_cmd_tx_cb()
might touch the freed structure.
This patch fixes this issue by canceling in-flight tx cmd if submitted
urb timed out.

Summary
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Fix data-race around unix_tot_inflight.
unix_tot_inflight is changed under spin_lock(unix_gc_lock), but
unix_release_sock() reads it locklessly.
Let's use READ_ONCE() for unix_tot_inflight.
Note that the writer side was marked by commit 9d6d7f1cb67c ("af_unix:
annote lockless accesses to unix_tot_inflight & gc_in_progress")
BUG: KCSAN: data-race in unix_inflight / unix_release_sock

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: set __exception_irq_entry with __irq_entry as a default
filter_irq_stacks() is supposed to cut entries which are related irq entries
from its call stack.
And in_irqentry_text() which is called by filter_irq_stacks()
uses __irqentry_text_start/end symbol to find irq entries in callstack.
But it doesn't work correctly as without "CONFIG_FUNCTION_GRAPH_TRACER",
arm64 kernel doesn't include gic_handle_irq which is entry point of arm64 irq
between __irqentry_text_start and __irqentry_text_end as we discussed in below link.
https://lore.kernel.org/all/CACT4Y+aReMGLYua2rCLHgFpS9io5cZC04Q8GLs-uNmrn1ezxYQ@mail.gmail.com/#t
This problem can makes unintentional deep call stack entries especially
in KASAN enabled situation as below.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/atom: Check kcalloc() for WS buffer in amdgpu_atom_execute_table_locked()
kcalloc() may fail. When WS is non-zero and allocation fails, ectx.ws
remains NULL while ectx.ws_size is set, leading to a potential NULL
pointer dereference in atom_get_src_int() when accessing WS entries.
Return -ENOMEM on allocation failure to avoid the NULL dereference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
power: supply: adp5061: fix out-of-bounds read in adp5061_get_chg_type()
ADP5061_CHG_STATUS_1_CHG_STATUS is masked with 0x07, which means a length
of 8, but adp5061_chg_type array size is 4, may end up reading 4 elements
beyond the end of the adp5061_chg_type[] array.

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: 8250: Reinit port->pm on port specific driver unbind
When we unbind a serial port hardware specific 8250 driver, the generic
serial8250 driver takes over the port. After that we see an oops about 10
seconds later. This can produce the following at least on some TI SoCs:
Unhandled fault: imprecise external abort (0x1406)
Internal error: : 1406 [#1] SMP ARM
Turns out that we may still have the serial port hardware specific driver
port->pm in use, and serial8250_pm() tries to call it after the port
specific driver is gone:
serial8250_pm [8250_base] from uart_change_pm+0x54/0x8c [serial_base]
uart_change_pm [serial_base] from uart_hangup+0x154/0x198 [serial_base]
uart_hangup [serial_base] from __tty_hangup.part.0+0x328/0x37c
__tty_hangup.part.0 from disassociate_ctty+0x154/0x20c
disassociate_ctty from do_exit+0x744/0xaac
do_exit from do_group_exit+0x40/0x8c
do_group_exit from __wake_up_parent+0x0/0x1c
Let's fix the issue by calling serial8250_set_defaults() in
serial8250_unregister_port(). This will set the port back to using
the serial8250 default functions, and sets the port->pm to point to
serial8250_pm.

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: fix a UAF when vma->mm is freed after vma->vm_refcnt got dropped
By inducing delays in the right places, Jann Horn created a reproducer for
a hard to hit UAF issue that became possible after VMAs were allowed to be
recycled by adding SLAB_TYPESAFE_BY_RCU to their cache.
Race description is borrowed from Jann's discovery report:
lock_vma_under_rcu() looks up a VMA locklessly with mas_walk() under
rcu_read_lock(). At that point, the VMA may be concurrently freed, and it
can be recycled by another process. vma_start_read() then increments the
vma->vm_refcnt (if it is in an acceptable range), and if this succeeds,
vma_start_read() can return a recycled VMA.
In this scenario where the VMA has been recycled, lock_vma_under_rcu()
will then detect the mismatching ->vm_mm pointer and drop the VMA through
vma_end_read(), which calls vma_refcount_put(). vma_refcount_put() drops
the refcount and then calls rcuwait_wake_up() using a copy of vma->vm_mm.
This is wrong: It implicitly assumes that the caller is keeping the VMA's
mm alive, but in this scenario the caller has no relation to the VMA's mm,
so the rcuwait_wake_up() can cause UAF.
The diagram depicting the race:
T1 T2 T3
== == ==
lock_vma_under_rcu
mas_walk
<VMA gets removed from mm>
mmap
<the same VMA is reallocated>
vma_start_read
__refcount_inc_not_zero_limited_acquire
munmap
__vma_enter_locked
refcount_add_not_zero
vma_end_read
vma_refcount_put
__refcount_dec_and_test
rcuwait_wait_event
<finish operation>
rcuwait_wake_up [UAF]
Note that rcuwait_wait_event() in T3 does not block because refcount was
already dropped by T1. At this point T3 can exit and free the mm causing
UAF in T1.
To avoid this we move vma->vm_mm verification into vma_start_read() and
grab vma->vm_mm to stabilize it before vma_refcount_put() operation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: smscufx: Fix several use-after-free bugs
Several types of UAFs can occur when physically removing a USB device.
Adds ufx_ops_destroy() function to .fb_destroy of fb_ops, and
in this function, there is kref_put() that finally calls ufx_free().
This fix prevents multiple UAFs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qedf: Fix NULL dereference in error handling
Smatch reported:
drivers/scsi/qedf/qedf_main.c:3056 qedf_alloc_global_queues()
warn: missing unwind goto?
At this point in the function, nothing has been allocated so we can return
directly. In particular the "qedf->global_queues" have not been allocated
so calling qedf_free_global_queues() will lead to a NULL dereference when
we check if (!gl[i]) and "gl" is NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs: Protect reconfiguration of sb read-write from racing writes
The reconfigure / remount code takes a lot of effort to protect
filesystem's reconfiguration code from racing writes on remounting
read-only. However during remounting read-only filesystem to read-write
mode userspace writes can start immediately once we clear SB_RDONLY
flag. This is inconvenient for example for ext4 because we need to do
some writes to the filesystem (such as preparation of quota files)
before we can take userspace writes so we are clearing SB_RDONLY flag
before we are fully ready to accept userpace writes and syzbot has found
a way to exploit this [1]. Also as far as I'm reading the code
the filesystem remount code was protected from racing writes in the
legacy mount path by the mount's MNT_READONLY flag so this is relatively
new problem. It is actually fairly easy to protect remount read-write
from racing writes using sb->s_readonly_remount flag so let's just do
that instead of having to workaround these races in the filesystem code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
binder: fix memory leak in binder_init()
In binder_init(), the destruction of binder_alloc_shrinker_init() is not
performed in the wrong path, which will cause memory leaks. So this commit
introduces binder_alloc_shrinker_exit() and calls it in the wrong path to
fix that.

unregistration and lookups can race, leading to:
1 use-after-free if an alias entry is removed while being read,
2 duplicate entries when two threads register the same alias,
3 inconsistent alias mappings observed by consumers.
Protect all traversals, insertions and deletions on
regulator_supply_alias_list with the existing regulator_list_mutex.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/net_failover: fix txq exceeding warning
The failover txq is inited as 16 queues.
when a packet is transmitted from the failover device firstly,
the failover device will select the queue which is returned from
the primary device if the primary device is UP and running.
If the primary device txq is bigger than the default 16,
it can lead to the following warning:
eth0 selects TX queue 18, but real number of TX queues is 16
The warning backtrace is:

Fix that by reducing txq number as the non-existent primary-dev does.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/vgem-fence: Fix potential deadlock on release
A timer that expires a vgem fence automatically in 10 seconds is now
released with timer_delete_sync() from fence->ops.release() called on last
dma_fence_put(). In some scenarios, it can run in IRQ context, which is
not safe unless TIMER_IRQSAFE is used. One potentially risky scenario was
demonstrated in Intel DRM CI trybot, BAT run on machine bat-adlp-6, while
working on new IGT subtests syncobj_timeline@stress-* as user space
replacements of some problematic test cases of a dma-fence-chain selftest
[1].

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb-storage: alauda: Fix uninit-value in alauda_check_media()
Syzbot got KMSAN to complain about access to an uninitialized value in
the alauda subdriver of usb-storage:
BUG: KMSAN: uninit-value in alauda_transport+0x462/0x57f0
drivers/usb/storage/alauda.c:1137
CPU: 0 PID: 12279 Comm: usb-storage Not tainted 5.3.0-rc7+ #0
Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS
Google 01/01/2011
Call Trace:
__dump_stack lib/dump_stack.c:77 [inline]
dump_stack+0x191/0x1f0 lib/dump_stack.c:113
kmsan_report+0x13a/0x2b0 mm/kmsan/kmsan_report.c:108
__msan_warning+0x73/0xe0 mm/kmsan/kmsan_instr.c:250
alauda_check_media+0x344/0x3310 drivers/usb/storage/alauda.c:460
The problem is that alauda_check_media() doesn't verify that its USB
transfer succeeded before trying to use the received data. What
should happen if the transfer fails isn't entirely clear, but a
reasonably conservative approach is to pretend that no media is
present.
A similar problem exists in a usb_stor_dbg() call in
alauda_get_media_status(). In this case, when an error occurs the
call is redundant, because usb_stor_ctrl_transfer() already will print
a debugging message.
Finally, unrelated to the uninitialized memory access, is the fact
that alauda_check_media() performs DMA to a buffer on the stack.
Fortunately usb-storage provides a general purpose DMA-able buffer for
uses like this. We'll use it instead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iavf: use internal state to free traffic IRQs
If the system tries to close the netdev while iavf_reset_task() is
running, __LINK_STATE_START will be cleared and netif_running() will
return false in iavf_reinit_interrupt_scheme(). This will result in

Summary
In the Linux kernel, the following vulnerability has been resolved:
staging: r8712: Fix memory leak in _r8712_init_xmit_priv()
In the above mentioned routine, memory is allocated in several places.
If the first succeeds and a later one fails, the routine will leak memory.
This patch fixes commit 2865d42c78a9 ("staging: r8712u: Add the new driver
to the mainline kernel"). A potential memory leak in
r8712_xmit_resource_alloc() is also addressed.

The process like this:
(CPU1) | (CPU2)
---------------------------------|-------------------------------
inet_create() |
// init clcsock to NULL |
sk = sk_alloc() |
|
// unexpectedly change clcsock |
inet_init_csk_locks() |
|
// add sk to hash table |
smc_inet_init_sock() |
smc_sk_init() |
smc_hash_sk() |
| // traverse the hash table
| smc_diag_dump_proto
| __smc_diag_dump()
| // visit wrong clcsock
| smc_diag_msg_common_fill()
// alloc clcsock |
smc_create_clcsk |
sock_create_kern |
With CONFIG_DEBUG_LOCK_ALLOC=y, the smc->clcsock is unexpectedly changed
in inet_init_csk_locks(). The INET_PROTOSW_ICSK flag is no need by smc,
just remove it.
After removing the INET_PROTOSW_ICSK flag, this patch alse revert
commit 6fd27ea183c2 ("net/smc: fix lacks of icsk_syn_mss with IPPROTO_SMC")
to avoid casting smc_sock to inet_connection_sock.

The BUG_ON() is triggered at here:
/* Dispose of resources used by a node */
void hfs_bnode_put(struct hfs_bnode *node)
{
if (node) {
<skipped>
BUG_ON(!atomic_read(&node->refcnt)); <- we have issue here!!!!
<skipped>
}
}
By tracing the refcnt, I found the node is created by hfs_bmap_alloc()
with refcnt 1. Then the node is used by hfs_btree_write(). There is a
missing of hfs_bnode_get() after find the node. The issue happened in
following path:
<alloc>
hfs_bmap_alloc
hfs_bnode_find
__hfs_bnode_create <- allocate a new node with refcnt 1.
hfs_bnode_put <- decrease the refcnt
<write>
hfs_btree_write
hfs_bnode_find
__hfs_bnode_create
hfs_bnode_findhash <- find the node without refcnt increased.
hfs_bnode_put <- trigger the BUG_ON() since refcnt is 0.

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
pid: Add a judgment for ns null in pid_nr_ns
__task_pid_nr_ns
ns = task_active_pid_ns(current);
pid_nr_ns(rcu_dereference(*task_pid_ptr(task, type)), ns);
if (pid && ns->level <= pid->level) {
Sometimes null is returned for task_active_pid_ns. Then it will trigger kernel panic in pid_nr_ns.
For example:
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000058

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/a6xx: Fix kvzalloc vs state_kcalloc usage
adreno_show_object() is a trap! It will re-allocate the pointer it is
passed on first call, when the data is ascii85 encoded, using kvmalloc/
kvfree(). Which means the data *passed* to it must be kvmalloc'd, ie.
we cannot use the state_kcalloc() helper.
This partially reverts commit ec8f1813bf8d ("drm/msm/a6xx: Replace
kcalloc() with kvzalloc()"), but adds the missing kvfree() to fix the
memory leak that was present previously. And adds a warning comment.

No race or attacker-uncontrollable memory-layout precondition is required.\nPR:L - Unprivileged users can open /dev/dri/renderD* and hang the GPU. On the primary msm deployments (ChromeOS/Android), crash_reporter/udev_collector automatically reads /sys/class/devcoredump/devcdN/data for the adreno driver, invoking the bad kvfree without the attacker needing root. Choosing the higher-severity PR:L over PR:H for that reasonable scenario.\nUI:N - The attacker submits the hanging GPU work themselves, and automatic device-coredump collection invokes a6xx_show without any separate victim mount/open/interactive action.\nS:U - The invalid free corrupts host kernel allocator state within the same OS security authority; this is a local privilege-escalation class bug, not a VM escape, IOMMU bypass, or other cross-boundary impact.\nC:H - adreno_show_object() kvfree()s an interior pointer into a state_kcalloc() memobj (past list_head), corrupting kvmalloc/SLUB freelist metadata; that heap corruption can be leveraged for arbitrary kernel memory disclosure, matching kernel CVSS guidance for memory-corruption bugs.\nI:H - The same interior-pointer free (and subsequent double-free of the memobj on a6xx_gpu_state_destroy) corrupts heap freelists and adjacent objects, enabling reuse and write/control-flow hijacking primitives rather than a benign bounded fault.\nA:H - The gitlab issue closed by the fix reports that reading the devcoredump triggers memory corruption; invalid free/double-free produce kernel oops/panic, which is Availability High under kernel CVSS guidance."

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: api - Use work queue in crypto_destroy_instance
The function crypto_drop_spawn expects to be called in process
context. However, when an instance is unregistered while it still
has active users, the last user may cause the instance to be freed
in atomic context.
Fix this by delaying the freeing to a work queue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Fix race condition in hidp_session_thread
There is a potential race condition in hidp_session_thread that may
lead to use-after-free. For instance, the timer is active while
hidp_del_timer is called in hidp_session_thread(). After hidp_session_put,
then 'session' will be freed, causing kernel panic when hidp_idle_timeout
is running.
The solution is to use del_timer_sync instead of del_timer.
Here is the call trace:

The attempt can be repeated indefinitely by reconnecting.\nPR:N - The attacker needs no account or privileges on the target host; it acts purely as a Bluetooth HID peripheral, and Linux HID hosts of this era accepted HID connections from unbonded peers. All required actions are ordinary HIDP protocol traffic.\nUI:N - The HIDP session is established and torn down by the Bluetooth daemon automatically in response to the peer\u0027s connection and its subsequent disconnect/unplug; no victim action is required at any point.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - hidp_idle_timeout() reads pointer fields (intr_sock/ctrl_sock) out of the freed hidp_session and follows them, and the resulting UAF primitive over a plain-kfree\u0027d heap object can be leveraged with heap grooming to disclose arbitrary kernel memory.\nI:H - The callback writes EUNATCH through a pointer read from freed memory and performs wake_up_interruptible() on a waitqueue head taken from that freed object, giving both a controlled write and an indirect call through an attacker-groomable function pointer \u2014 sufficient for control-flow hijack.\nA:H - The reported symptom is a kernel panic from the timer callback running against a freed session; any such use-after-free reliably oopses the kernel and can be triggered repeatedly by a nearby device."

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

Containers with Docker\u0027s default capability set (which includes NET_RAW) also reach this directly.\nUI:N - The attacker performs every step \u2014 socket setup, ring teardown, interface flap, and packet injection \u2014 with no action from any other user.\nS:U - The corruption is confined to kernel memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - tpacket_rcv() operates on the freed pg_vec pages and stale prb_bdqc pointers, and the reclaimed pages remain user-mmapped via packet_mmap(), giving the attacker a read window onto whatever kernel data is reallocated into them \u2014 an arbitrary kernel memory disclosure primitive.\nI:H - skb_copy_bits() and prb_fill_curr_block() write attacker-chosen packet contents and block metadata into freed ring pages after free_pg_vec(), yielding a controlled use-after-free write that is heap-sprayable into privilege escalation.\nA:H - In the simplest outcome, packet_lookup_frame() dereferences a NULL rb-\u003epg_vec and test_bit() a NULL rx_owner_map from softirq context, causing an immediate kernel oops/panic that any local user can trigger at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/irdma: Fix memory leak of PBLE objects
On rmmod of irdma, the PBLE object memory is not being freed. PBLE object
memory are not statically pre-allocated at function initialization time
unlike other HMC objects. PBLEs objects and the Segment Descriptors (SD)
for it can be dynamically allocated during scale up and SD's remain
allocated till function deinitialization.
Fix this leak by adding IRDMA_HMC_IW_PBLE to the iw_hmc_obj_types[] table
and skip pbles in irdma_create_hmc_obj but not in irdma_del_hmc_objects().

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix failed to find the peer with peer_id 0 when disconnected
It has a fail log which is ath11k_dbg in ath11k_dp_rx_process_mon_status(),
as below, it will not print when debug_mask is not set ATH11K_DBG_DATA.
ath11k_dbg(ab, ATH11K_DBG_DATA,
"failed to find the peer with peer_id %d\n",
ppdu_info.peer_id);
When run scan with station disconnected, the peer_id is 0 for case
HAL_RX_MPDU_START in ath11k_hal_rx_parse_mon_status_tlv() which called
from ath11k_dp_rx_process_mon_status(), and the peer_id of ppdu_info is
reset to 0 in the while loop, so it does not match condition of the
check "if (ppdu_info->peer_id == HAL_INVALID_PEERID" in the loop, and
then the log "failed to find the peer with peer_id 0" print after the
check in the loop, it is below call stack when debug_mask is set
ATH11K_DBG_DATA.
The reason is this commit 01d2f285e3e5 ("ath11k: decode HE status tlv")
add "memset(ppdu_info, 0, sizeof(struct hal_rx_mon_ppdu_info))" in
ath11k_dp_rx_process_mon_status(), but the commit does not initialize
the peer_id to HAL_INVALID_PEERID, then lead the check mis-match.
Callstack of the failed log:

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix shift-out-of-bounds due to too large exponent of block size
If field s_log_block_size of superblock data is corrupted and too large,
init_nilfs() and load_nilfs() still can trigger a shift-out-of-bounds
warning followed by a kernel panic (if panic_on_warn is set):
shift exponent 38973 is too large for 32-bit type 'int'
Call Trace:
<TASK>
dump_stack_lvl+0xcd/0x134

...
This fixes the issue by adding and using a new helper function for getting
block size with sanity check.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: usb: qmi_wwan: initialize MAC header offset in qmimux_rx_fixup
Raw IP packets have no MAC header, leaving skb->mac_header uninitialized.
This can trigger kernel panics on ARM64 when xfrm or other subsystems
access the offset due to strict alignment checks.
Initialize the MAC header to prevent such crashes.
This can trigger kernel panics on ARM when running IPsec over the
qmimux0 interface.

The attacker can repeat it per packet and choose the written value via the inner IP version.\nPR:N - The xfrm tunnel type ipip_xfrm_rcv() performs no cryptographic verification at all and its SA is matched by source address, so a spoofed IP-in-IP packet reaches the vulnerable decap with no credentials. Even in the ESP case the triggering peer holds no privileges or account on the target device.\nUI:N - The corruption occurs entirely in the NET_RX softirq receive path when a packet arrives. No action by any local user or administrator is required.\nS:U - The out-of-bounds write and the resulting crash are confined to the kernel\u0027s own memory and security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The bug is a genuine out-of-bounds heap write roughly 64KB past the skb buffer, and such corruption of an adjacent object\u0027s length/offset field is a standard route to kernel memory disclosure.

Out-of-bounds writes are exploitable for control-flow hijacking, and here it can also silently corrupt live kernel objects without crashing.\nA:H - The reported ARM64 oops (write permission fault in xfrm_input, in softirq context) is reproduced by every received IPsec packet, and embedded/industrial routers typically run panic_on_oops, giving a full device outage.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: wacom: Use ktime_t rather than int when dealing with timestamps
Code which interacts with timestamps needs to use the ktime_t type
returned by functions like ktime_get. The int type does not offer
enough space to store these values, and attempting to use it is a
recipe for problems. In this particular case, overflows would occur
when calculating/storing timestamps leading to incorrect values being
reported to userspace. In some cases these bad timestamps cause input
handling in userspace to appear hung.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gvt: fix gvt debugfs destroy
When gvt debug fs is destroyed, need to have a sane check if drm
minor's debugfs root is still available or not, otherwise in case like
device remove through unbinding, drm minor's debugfs directory has
already been removed, then intel_gvt_debugfs_clean() would act upon
dangling pointer like below oops.
i915 0000:00:02.0: Direct firmware load for i915/gvt/vid_0x8086_did_0x1926_rid_0x0a.golden_hw_state failed with error -2

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: fix potential oops in cifs_oplock_break
With deferred close we can have closes that race with lease breaks,
and so with the current checks for whether to send the lease response,
oplock_response(), this can mean that an unmount (kill_sb) can occur
just before we were checking if the tcon->ses is valid. See below:

To fix this change the ordering of the checks before sending the oplock_response
to first check if the openFileList is empty.

This matches the treatment of other cifs client bugs driven by server-supplied data, including the identical CVE-2025-38527 in this same function.\nAC:L - The remote server controls the triggering side entirely and can send lease/oplock breaks continuously, and the same break drives `cifs_close_deferred_file()` on the other side; with the last handle the `kfree(tcon)` occurs synchronously inside `_cifsFileInfo_put()` rather than through a narrow window, and unmounts occur automatically in common autofs/automount deployments.\nPR:N - The attacker is the SMB server (or an MITM) and needs no credentials or privileges on the victim client; the client\u0027s own handling of a server-sent break notification is what enters the vulnerable path.\nUI:N - Against an already-mounted share the attack needs no victim action \u2014 the server sends break notifications on its own schedule and the teardown side is reached via deferred-close plus automatic/idle unmount rather than an interactive step.\nS:U - The use-after-free is in kernel memory and its impact stays within the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The freed `struct cifs_tcon` is dereferenced through a four-level pointer chain (`tcon-\u003eses-\u003eserver-\u003eops`) read from reallocated slab contents, which after heap grooming yields an arbitrary kernel read primitive; the oops itself shows the freed object already refilled with unrelated heap data.\nI:H - The stale pointer terminates in an indirect call `tcon-\u003eses-\u003eserver-\u003eops-\u003eoplock_response(tcon, ...)` where every pointer in the chain and the first argument come from freed, reallocatable memory, giving a control-flow hijack primitive and thus arbitrary kernel code execution.\nA:H - Even unexploited, the bug produces an immediate kernel oops (general protection fault from the non-canonical `ses` pointer in the reported trace), and it can be re-triggered repeatedly by the remote server."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: video: Fix use-after-free in acpi_video_switch_brightness()
The switch_brightness_work delayed work accesses device->brightness
and device->backlight, freed by acpi_video_dev_unregister_backlight()
during device removal.
If the work executes after acpi_video_bus_unregister_backlight()
frees these resources, it causes a use-after-free when
acpi_video_switch_brightness() dereferences device->brightness or
device->backlight.
Fix this by calling cancel_delayed_work_sync() for each device's
switch_brightness_work in acpi_video_bus_remove_notify_handler()
after removing the notify handler that queues the work. This ensures
the work completes before the memory is freed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
configfs: fix possible memory leak in configfs_create_dir()
kmemleak reported memory leaks in configfs_create_dir():
unreferenced object 0xffff888009f6af00 (size 192):
comm "modprobe", pid 3777, jiffies 4295537735 (age 233.784s)
backtrace:
kmem_cache_alloc (mm/slub.c:3250 mm/slub.c:3256 mm/slub.c:3263 mm/slub.c:3273)
new_fragment (./include/linux/slab.h:600 fs/configfs/dir.c:163)
configfs_register_subsystem (fs/configfs/dir.c:1857)
basic_write (drivers/hwtracing/stm/p_basic.c:14) stm_p_basic
do_one_initcall (init/main.c:1296)
do_init_module (kernel/module/main.c:2455)
...
unreferenced object 0xffff888003ba7180 (size 96):
comm "modprobe", pid 3777, jiffies 4295537735 (age 233.784s)
backtrace:
kmem_cache_alloc (mm/slub.c:3250 mm/slub.c:3256 mm/slub.c:3263 mm/slub.c:3273)
configfs_new_dirent (./include/linux/slab.h:723 fs/configfs/dir.c:194)
configfs_make_dirent (fs/configfs/dir.c:248)
configfs_create_dir (fs/configfs/dir.c:296)
configfs_attach_group.isra.28 (fs/configfs/dir.c:816 fs/configfs/dir.c:852)
configfs_register_subsystem (fs/configfs/dir.c:1881)
basic_write (drivers/hwtracing/stm/p_basic.c:14) stm_p_basic
do_one_initcall (init/main.c:1296)
do_init_module (kernel/module/main.c:2455)
...
This is because the refcount is not correct in configfs_make_dirent().
For normal stage, the refcount is changing as:
configfs_register_subsystem()
configfs_create_dir()
configfs_make_dirent()
configfs_new_dirent() # set s_count = 1
dentry->d_fsdata = configfs_get(sd); # s_count = 2
...
configfs_unregister_subsystem()
configfs_remove_dir()
remove_dir()
configfs_remove_dirent() # s_count = 1
dput() ...
*dentry_unlink_inode()*
configfs_d_iput() # s_count = 0, release
However, if we failed in configfs_create():
configfs_register_subsystem()
configfs_create_dir()
configfs_make_dirent() # s_count = 2
...
configfs_create() # fail
->out_remove:
configfs_remove_dirent(dentry)
configfs_put(sd) # s_count = 1
return PTR_ERR(inode);
There is no inode in the error path, so the configfs_d_iput() is lost
and makes sd and fragment memory leaked.
To fix this, when we failed in configfs_create(), manually call
configfs_put(sd) to keep the refcount correct.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: guest_memfd: Remove bindings on memslot deletion when gmem is dying
When unbinding a memslot from a guest_memfd instance, remove the bindings
even if the guest_memfd file is dying, i.e. even if its file refcount has
gone to zero. If the memslot is freed before the file is fully released,
nullifying the memslot side of the binding in kvm_gmem_release() will
write to freed memory, as detected by syzbot+KASAN:

Deliberately don't acquire filemap invalid lock when the file is dying as
the lifecycle of f_mapping is outside the purview of KVM. Dereferencing
the mapping is *probably* fine, but there's no need to invalidate anything
as memslot deletion is responsible for zapping SPTEs, and the only code
that can access the dying file is kvm_gmem_release(), whose core code is
mutual

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/siw: Fix QP destroy to wait for all references dropped.
Delay QP destroy completion until all siw references to QP are
dropped. The calling RDMA core will free QP structure after
successful return from siw_qp_destroy() call, so siw must not
hold any remaining reference to the QP upon return.
A use-after-free was encountered in xfstest generic/460, while
testing NFSoRDMA. Here, after a TCP connection drop by peer,
the triggered siw_cm_work_handler got delayed until after
QP destroy call, referencing a QP which has already freed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/ieee802154: don't warn zero-sized raw_sendmsg()
syzbot is hitting skb_assert_len() warning at __dev_queue_xmit() [1],
for PF_IEEE802154 socket's zero-sized raw_sendmsg() request is hitting
__dev_queue_xmit() with skb->len == 0.
Since PF_IEEE802154 socket's zero-sized raw_sendmsg() request was
able to return 0, don't call __dev_queue_xmit() if packet length is 0.
----------
#include <sys/socket.h>
#include <netinet/in.h>
int main(int argc, char *argv[])
{
struct sockaddr_in addr = { .sin_family = AF_INET, .sin_addr.s_addr = htonl(INADDR_LOOPBACK) };
struct iovec iov = { };
struct msghdr hdr = { .msg_name = &addr, .msg_namelen = sizeof(addr), .msg_iov = &iov, .msg_iovlen = 1 };
sendmsg(socket(PF_IEEE802154, SOCK_RAW, 0), &hdr, 0);
return 0;
}
----------
Note that this might be a sign that commit fd1894224407c484 ("bpf: Don't
redirect packets with invalid pkt_len") should be reverted, for
skb->len == 0 was acceptable for at least PF_IEEE802154 socket.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: silence the warning when evicting inode with dioread_nolock
When evicting an inode with default dioread_nolock, it could be raced by
the unwritten extents converting kworker after writeback some new
allocated dirty blocks. It convert unwritten extents to written, the
extents could be merged to upper level and free extent blocks, so it
could mark the inode dirty again even this inode has been marked
I_FREEING. But the inode->i_io_list check and warning in
ext4_evict_inode() missing this corner case. Fortunately,
ext4_evict_inode() will wait all extents converting finished before this
check, so it will not lead to inode use-after-free problem, every thing
is OK besides this warning. The WARN_ON_ONCE was originally designed
for finding inode use-after-free issues in advance, but if we add
current dioread_nolock case in, it will become not quite useful, so fix
this warning by just remove this check.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix issue in verifying allow_ptr_leaks
After we converted the capabilities of our networking-bpf program from
cap_sys_admin to cap_net_admin+cap_bpf, our networking-bpf program
failed to start. Because it failed the bpf verifier, and the error log
is "R3 pointer comparison prohibited".
A simple reproducer as follows,
SEC("cls-ingress")
int ingress(struct __sk_buff *skb)
{
struct iphdr *iph = (void *)(long)skb->data + sizeof(struct ethhdr);
if ((long)(iph + 1) > (long)skb->data_end)
return TC_ACT_STOLEN;
return TC_ACT_OK;
}
Per discussion with Yonghong and Alexei [1], comparison of two packet
pointers is not a pointer leak. This patch fixes it.
Our local kernel is 6.1.y and we expect this fix to be backported to
6.1.y, so stable is CCed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
l2tp: close all race conditions in l2tp_tunnel_register()
The code in l2tp_tunnel_register() is racy in several ways:
1. It modifies the tunnel socket _after_ publishing it.
2. It calls setup_udp_tunnel_sock() on an existing socket without
locking.
3. It changes sock lock class on fly, which triggers many syzbot
reports.
This patch amends all of them by moving socket initialization code
before publishing and under sock lock. As suggested by Jakub, the
l2tp lockdep class is not necessary as we can just switch to
bh_lock_sock_nested().

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix lockdep splat and potential deadlock after failure running delayed items
When running delayed items we are holding a delayed node's mutex and then
we will attempt to modify a subvolume btree to insert/update/delete the
delayed items. However if have an error during the insertions for example,
btrfs_insert_delayed_items() may return with a path that has locked extent
buffers (a leaf at the very least), and then we attempt to release the
delayed node at __btrfs_run_delayed_items(), which requires taking the
delayed node's mutex, causing an ABBA type of deadlock. This was reported
by syzbot and the lockdep splat is the following:

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sxgbe: fix potential NULL dereference in sxgbe_rx()
Currently, when skb is null, the driver prints an error and then
dereferences skb on the next line.
To fix this, let's add a 'break' after the error message to switch

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: detect invalid INLINE_DATA + EXTENTS flag combination
syzbot reported a BUG_ON in ext4_es_cache_extent() when opening a verity
file on a corrupted ext4 filesystem mounted without a journal.
The issue is that the filesystem has an inode with both the INLINE_DATA
and EXTENTS flags set:
EXT4-fs error (device loop0): ext4_cache_extents:545: inode #15:
comm syz.0.17: corrupted extent tree: lblk 0 < prev 66
Investigation revealed that the inode has both flags set:
DEBUG: inode 15 - flag=1, i_inline_off=164, has_inline=1, extents_flag=1
This is an invalid combination since an inode should have either:
- INLINE_DATA: data stored directly in the inode
- EXTENTS: data stored in extent-mapped blocks
Having both flags causes ext4_has_inline_data() to return true, skipping
extent tree validation in __ext4_iget(). The unvalidated out-of-order
extents then trigger a BUG_ON in ext4_es_cache_extent() due to integer
underflow when calculating hole sizes.
Fix this by detecting this invalid flag combination early in ext4_iget()
and rejecting the corrupted inode.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vdpa/vp_vdpa: fix kfree a wrong pointer in vp_vdpa_remove
In vp_vdpa_remove(), the code kfree(&vp_vdpa_mgtdev->mgtdev.id_table) uses
a reference of pointer as the argument of kfree, which is the wrong pointer
and then may hit crash like this:

Summary
In the Linux kernel, the following vulnerability has been resolved:
comedi: c6xdigio: Fix invalid PNP driver unregistration
The Comedi low-level driver "c6xdigio" seems to be for a parallel port
connected device. When the Comedi core calls the driver's Comedi
"attach" handler `c6xdigio_attach()` to configure a Comedi to use this
driver, it tries to enable the parallel port PNP resources by
registering a PNP driver with `pnp_register_driver()`, but ignores the
return value. (The `struct pnp_driver` it uses has only the `name` and
`id_table` members filled in.) The driver's Comedi "detach" handler
`c6xdigio_detach()` unconditionally unregisters the PNP driver with
`pnp_unregister_driver()`.
It is possible for `c6xdigio_attach()` to return an error before it
calls `pnp_register_driver()` and it is possible for the call to
`pnp_register_driver()` to return an error (that is ignored). In both
cases, the driver should not be calling `pnp_unregister_driver()` as it
does in `c6xdigio_detach()`. (Note that `c6xdigio_detach()` will be
called by the Comedi core if `c6xdigio_attach()` returns an error, or if
the Comedi core decides to detach the Comedi device from the driver for
some other reason.)
The unconditional call to `pnp_unregister_driver()` without a previous
successful call to `pnp_register_driver()` will cause
`driver_unregister()` to issue a warning "Unexpected driver
unregister!". This was detected by Syzbot [1].
Also, the PNP driver registration and unregistration should be done at
module init and exit time, respectively, not when attaching or detaching
Comedi devices to the driver. (There might be more than one Comedi
device being attached to the driver, although that is unlikely.)
Change the driver to do the PNP driver registration at module init time,
and the unregistration at module exit time. Since `c6xdigio_detach()`
now only calls `comedi_legacy_detach()`, remove the function and change
the Comedi driver "detach" handler to `comedi_legacy_detach`.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncomedi: c6xdigio: Fix invalid PNP driver unregistration\n\nThe Comedi low-level driver \"c6xdigio\" seems to be for a parallel port\nconnected device. When the Comedi core calls the driver\u0027s Comedi\n\"attach\" handler `c6xdigio_attach()` to configure a Comedi to use this\ndriver, it tries to enable the parallel port PNP resources by\nregistering a PNP driver with `pnp_register_driver()`, but ignores the\nreturn value. (The `struct pnp_driver` it uses has only the `name` and\n`id_table` members filled in.) The driver\u0027s Comedi \"detach\" handler\n`c6xdigio_detach()` unconditionally unregisters the PNP driver with\n`pnp_unregister_driver()`.\n\nIt is possible for `c6xdigio_attach()` to return an error before it\ncalls `pnp_register_driver()` and it is possible for the call to\n`pnp_register_driver()` to return an error (that is ignored). In both\ncases, the driver should not be calling `pnp_unregister_driver()` as it\ndoes in `c6xdigio_detach()`. (Note that `c6xdigio_detach()` will be\ncalled by the Comedi core if `c6xdigio_attach()` returns an error, or if\nthe Comedi core decides to detach the Comedi device from the driver for\nsome other reason.)\n\nThe unconditional call to `pnp_unregister_driver()` without a previous\nsuccessful call to `pnp_register_driver()` will cause\n`driver_unregister()` to issue a warning \"Unexpected driver\nunregister!\". This was detected by Syzbot [1].\n\nAlso, the PNP driver registration and unregistration should be done at\nmodule init and exit time, respectively, not when attaching or detaching\nComedi devices to the driver. (There might be more than one Comedi\ndevice being attached to the driver, although that is unlikely.)\n\nChange the driver to do the PNP driver registration at module init time,\nand the unregistration at module exit time. Since `c6xdigio_detach()`\nnow only calls `comedi_legacy_detach()`, remove the function and change\nthe Comedi driver \"detach\" handler to `comedi_legacy_detach`.\n\n-------------------------------------------\n[1] Syzbot sample crash report:\nUnexpected driver unregister!\nWARNING: CPU: 0 PID: 5970 at drivers/base/driver.c:273 driver_unregister drivers/base/driver.c:273 [inline]\nWARNING: CPU: 0 PID: 5970 at drivers/base/driver.c:273 driver_unregister+0x90/0xb0 drivers/base/driver.c:270\nModules linked in:\nCPU: 0 UID: 0 PID: 5970 Comm: syz.0.17 Not tainted syzkaller #0 PREEMPT(full)\nHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 10/02/2025\nRIP: 0010:driver_unregister drivers/base/driver.c:273 [inline]\nRIP: 0010:driver_unregister+0x90/0xb0 drivers/base/driver.c:270\nCode: 48 89 ef e8 c2 e6 82 fc 48 89 df e8 3a 93 ff ff 5b 5d e9 c3 6d d9 fb e8 be 6d d9 fb 90 48 c7 c7 e0 f8 1f 8c e8 51 a2 97 fb 90 \u003c0f\u003e 0b 90 90 5b 5d e9 a5 6d d9 fb e8 e0 f4 41 fc eb 94 e8 d9 f4 41\nRSP: 0018:ffffc9000373f9a0 EFLAGS: 00010282\nRAX: 0000000000000000 RBX: ffffffff8ff24720 RCX: ffffffff817b6ee8\nRDX: ffff88807c932480 RSI: ffffffff817b6ef5 RDI: 0000000000000001\nRBP: 0000000000000000 R08: 0000000000000001 R09: 0000000000000000\nR10: 0000000000000001 R11: 0000000000000001 R12: ffffffff8ff24660\nR13: dffffc0000000000 R14: 0000000000000000 R15: ffff88814cca0000\nFS: 000055556dab1500(0000) GS:ffff8881249d9000(0000) knlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 000055f77f285cd0 CR3: 000000007d871000 CR4: 00000000003526f0\nCall Trace:\n \u003cTASK\u003e\n comedi_device_detach_locked+0x12f/0xa50 drivers/comedi/drivers.c:207\n comedi_device_detach+0x67/0xb0 drivers/comedi/drivers.c:215\n comedi_device_attach+0x43d/0x900 drivers/comedi/drivers.c:1011\n do_devconfig_ioctl+0x1b1/0x710 drivers/comedi/comedi_fops.c:872\n comedi_unlocked_ioctl+0x165d/0x2f00 drivers/comedi/comedi_fops.c:2178\n vfs_ioctl fs/ioctl.c:51 [inline]\n __do_sys_ioctl fs/ioctl.c:597 [inline]\n __se_sys_ioctl fs/ioctl.c:583 [inline]\n __x64_sys_ioctl+0x18e/0x210 fs/ioctl.c:583\n do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline]\n do_sys\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix deadlock when converting an inline directory in nojournal mode
In no journal mode, ext4_finish_convert_inline_dir() can self-deadlock
by calling ext4_handle_dirty_dirblock() when it already has taken the
directory lock. There is a similar self-deadlock in
ext4_incvert_inline_data_nolock() for data files which we'll fix at
the same time.
A simple reproducer demonstrating the problem:
mke2fs -Fq -t ext2 -O inline_data -b 4k /dev/vdc 64
mount -t ext4 -o dirsync /dev/vdc /vdc
cd /vdc
mkdir file0
cd file0
touch file0
touch file1
attr -s BurnSpaceInEA -V abcde .
touch supercalifragilisticexpialidocious

Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock: Ignore signal/timeout on connect() if already established
During connect(), acting on a signal/timeout by disconnecting an already
established socket leads to several issues:
1. connect() invoking vsock_transport_cancel_pkt() ->
virtio_transport_purge_skbs() may race with sendmsg() invoking
virtio_transport_get_credit(). This results in a permanently elevated
`vvs->bytes_unsent`. Which, in turn, confuses the SOCK_LINGER handling.
2. connect() resetting a connected socket's state may race with socket
being placed in a sockmap. A disconnected socket remaining in a sockmap
breaks sockmap's assumptions. And gives rise to WARNs.
3. connect() transitioning SS_CONNECTED -> SS_UNCONNECTED allows for a
transport change/drop after TCP_ESTABLISHED. Which poses a problem for
any simultaneous sendmsg() or connect() and may result in a
use-after-free/null-ptr-deref.
Do not disconnect socket on signal/timeout. Keep the logic for unconnected
sockets: they don't linger, can't be placed in a sockmap, are rejected by
sendmsg().

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: kvaser_usb: leaf: Fix potential infinite loop in command parsers
The `kvaser_usb_leaf_wait_cmd()` and `kvaser_usb_leaf_read_bulk_callback`
functions contain logic to zero-length commands. These commands are used
to align data to the USB endpoint's wMaxPacketSize boundary.
The driver attempts to skip these placeholders by aligning the buffer
position `pos` to the next packet boundary using `round_up()` function.
However, if zero-length command is found exactly on a packet boundary
(i.e., `pos` is a multiple of wMaxPacketSize, including 0), `round_up`
function will return the unchanged value of `pos`. This prevents `pos`
to be increased, causing an infinite loop in the parsing logic.
This patch fixes this in the function by using `pos + 1` instead.
This ensures that even if `pos` is on a boundary, the calculation is
based on `pos + 1`, forcing `round_up()` to always return the next
aligned boundary.

Summary
In the Linux kernel, the following vulnerability has been resolved:
futex: Prevent use-after-free during requeue-PI
syzbot managed to trigger the following race:
T1 T2
futex_wait_requeue_pi()
futex_do_wait()
schedule()
futex_requeue()
futex_proxy_trylock_atomic()
futex_requeue_pi_prepare()
requeue_pi_wake_futex()
futex_requeue_pi_complete()
/* preempt */
* timeout/ signal wakes T1 *
futex_requeue_pi_wakeup_sync() // Q_REQUEUE_PI_LOCKED
futex_hash_put()
// back to userland, on stack futex_q is garbage
/* back */
wake_up_state(q->task, TASK_NORMAL);
In this scenario futex_wait_requeue_pi() is able to leave without using
futex_q::lock_ptr for synchronization.
This can be prevented by reading futex_q::task before updating the
futex_q::requeue_state. A reference on the task_struct is not needed
because requeue_pi_wake_futex() is invoked with a spinlock_t held which
implies a RCU read section.
Even if T1 terminates immediately after, the task_struct will remain valid
during T2's wake_up_state(). A READ_ONCE on futex_q::task before
futex_requeue_pi_complete() is enough because it ensures that the variable
is read before the state is updated.
Read futex_q::task before updating the requeue state, use it for the
following wakeup.

There is no remote or adjacent-network path into kernel/futex/requeue.c.\nAC:L - The attacker controls both sides of the race: it creates the waiter thread with an attacker-chosen short timeout (or delivers a signal) and simultaneously issues the requeue from a second thread, and can retry the loop millions of times with CPU pinning and interrupt pressure to hit the window between futex_requeue_pi_complete() and wake_up_state(). syzbot hit it with random fuzzing, and on PREEMPT_RT the hb spinlock_t is preemptible, making the window wide.\nPR:L - Any unprivileged local user can call futex() with FUTEX_WAIT_REQUEUE_PI/FUTEX_CMP_REQUEUE_PI; do_futex() and futex_requeue() contain no capability or credential checks, and CONFIG_FUTEX_PI is default-y. The path is reachable from inside containers and sandboxes with no elevated privileges.\nUI:N - The attacker\u0027s own two threads perform every step of the exploit; no victim action, mount, or file open is involved.\nS:U - The corruption occurs in kernel memory (a stale kernel stack frame and a type-confused task_struct) and stays within the kernel\u0027s own security authority. No VM, IOMMU, or hypervisor boundary is crossed.\nC:H - This is a use-after-free read of the waiter\u0027s dead kernel stack frame, and the resulting attacker-influenced task_struct pointer is dereferenced in try_to_wake_up() (p-\u003e__state, p-\u003esaved_state, p-\u003eon_rq, p-\u003esched_class), giving an arbitrary kernel-memory read/oracle primitive. Per UAF guidance this is High.\nI:H - The stale futex_q lives on the attacker\u0027s own kernel stack, which can be refilled with controlled bytes by an immediately following syscall, so q-\u003etask becomes an attacker-chosen pointer; try_to_wake_up() then writes to it (raw_spin_lock on p-\u003epi_lock, WRITE_ONCE(p-\u003e__state, TASK_RUNNING), runqueue list manipulation) and makes an indirect call through p-\u003esched_class-\u003eenqueue_task(), a plausible local privilege-escalation path.\nA:H - In the unexploited case wake_up_state() dereferences a wild pointer from reused stack memory, causing an immediate oops/panic, and corrupting scheduler runqueue state can hang the machine. Any use-after-free of this kind is a High availability impact."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: use dst_dev_rcu() in sk_setup_caps()
Use RCU to protect accesses to dst->dev from sk_setup_caps()
and sk_dst_gso_max_size().
Also use dst_dev_rcu() in ip6_dst_mtu_maybe_forward(),
and ip_dst_mtu_maybe_forward().
ip4_dst_hoplimit() can use dst_dev_net_rcu().

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: Fix lost destroy smbd connection when MR allocate failed
If the MR allocate failed, the smb direct connection info is NULL,
then smbd_destroy() will directly return, then the connection info
will be leaked.
Let's set the smb direct connection info to the server before call
smbd_destroy().

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Prevent lpfc_debugfs_lockstat_write() buffer overflow
A static code analysis tool flagged the possibility of buffer overflow when
using copy_from_user() for a debugfs entry.
Currently, it is possible that copy_from_user() copies more bytes than what
would fit in the mybuf char array. Add a min() restriction check between
sizeof(mybuf) - 1 and nbytes passed from the userspace buffer to protect
against buffer overflow.

Summary
In the Linux kernel, the following vulnerability has been resolved:
soundwire: fix enumeration completion
The soundwire subsystem uses two completion structures that allow
drivers to wait for soundwire device to become enumerated on the bus and
initialised by their drivers, respectively.
The code implementing the signalling is currently broken as it does not
signal all current and future waiters and also uses the wrong
reinitialisation function, which can potentially lead to memory
corruption if there are still waiters on the queue.
Not signalling future waiters specifically breaks sound card probe
deferrals as codec drivers can not tell that the soundwire device is
already attached when being reprobed. Some codec runtime PM
implementations suffer from similar problems as waiting for enumeration
during resume can also timeout despite the device already having been
enumerated.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: bus: verify partner exists in typec_altmode_attention
Some usb hubs will negotiate DisplayPort Alt mode with the device
but will then negotiate a data role swap after entering the alt
mode. The data role swap causes the device to unregister all alt
modes, however the usb hub will still send Attention messages
even after failing to reregister the Alt Mode. type_altmode_attention
currently does not verify whether or not a device's altmode partner
exists, which results in a NULL pointer error when dereferencing
the typec_altmode and typec_altmode_ops belonging to the altmode
partner.
Verify the presence of a device's altmode partner before sending
the Attention message to the Alt Mode driver.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: imx_sc_key - fix memory corruption on unload
This is supposed to be "priv" but we accidentally pass "&priv" which is
an address in the stack and so it will lead to memory corruption when
the imx_sc_key_action() function is called. Remove the &.

Summary
In the Linux kernel, the following vulnerability has been resolved:
virt/coco/sev-guest: Double-buffer messages
The encryption algorithms read and write directly to shared unencrypted
memory, which may leak information as well as permit the host to tamper
with the message integrity. Instead, copy whole messages in or out as
needed before doing any computation on them.

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

__dquot_initialize
__dquot_initialize
dqget
if (!test_bit(DQ_ACTIVE_B, &dquot->dq_flags))

dquot_disable
invalidate_dquots
if (atomic_read(&dquot->dq_count))
dqgrab
WARN_ON_ONCE(!test_bit(DQ_ACTIVE_B, &dquot->dq_flags))
-> Trigger warning
In the above scenario, 'dquot->dq_flags' has no DQ_ACTIVE_B is normal when
dqgrab().
To solve above issue just replace the dqgrab() use in invalidate_dquots() with
atomic_inc(&dquot->dq_count).

Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: handle data disappearing from under the TLS ULP
TLS expects that it owns the receive queue of the TCP socket.
This cannot be guaranteed in case the reader of the TCP socket
entered before the TLS ULP was installed, or uses some non-standard
read API (eg. zerocopy ones). Replace the WARN_ON() and a buggy
early exit (which leaves anchor pointing to a freed skb) with real
error handling. Wipe the parsing state and tell the reader to retry.
We already reload the anchor every time we (re)acquire the socket lock,
so the only condition we need to avoid is an out of bounds read
(not having enough bytes in the socket for previously parsed record len).
If some data was read from under TLS but there's enough in the queue
we'll reload and decrypt what is most likely not a valid TLS record.
Leading to some undefined behavior from TLS perspective (corrupting
a stream? missing an alert? missing an attack?) but no kernel crash
should take place.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: set page extent mapped after read_folio in relocate_one_page
One of the CI runs triggered the following panic
assertion failed: PagePrivate(page) && page->private, in fs/btrfs/subpage.c:229

Code: 91098021 b0007fa0 91346000 97e9c6d2 (d4210000)
This is the same problem outlined in 17b17fcd6d44 ("btrfs:
set_page_extent_mapped after read_folio in btrfs_cont_expand") , and the
fix is the same. I originally looked for the same pattern elsewhere in
our code, but mistakenly skipped over this code because I saw the page
cache readahead before we set_page_extent_mapped, not realizing that
this was only in the !page case, that we can still end up with a
!uptodate page and then do the btrfs_read_folio further down.
The fix here is the same as the above mentioned patch, move the
set_page_extent_mapped call to after the btrfs_read_folio() block to
make sure that we have the subpage blocksize stuff setup properly before
using the page.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tipc: Fix use-after-free in tipc_mon_reinit_self().
syzbot reported use-after-free of tipc_net(net)->monitors[]
in tipc_mon_reinit_self(). [0]
The array is protected by RTNL, but tipc_mon_reinit_self()
iterates over it without RTNL.
tipc_mon_reinit_self() is called from tipc_net_finalize(),
which is always under RTNL except for tipc_net_finalize_work().
Let's hold RTNL in tipc_net_finalize_work().
[0]:

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSD: free copynotify stateid in nfs4_free_ol_stateid()
Typically copynotify stateid is freed either when parent's stateid
is being close/freed or in nfsd4_laundromat if the stateid hasn't
been used in a lease period.
However, in case when the server got an OPEN (which created
a parent stateid), followed by a COPY_NOTIFY using that stateid,
followed by a client reboot. New client instance while doing
CREATE_SESSION would force expire previous state of this client.
It leads to the open state being freed thru release_openowner->
nfs4_free_ol_stateid() and it finds that it still has copynotify
stateid associated with it. We currently print a warning and is
triggerred
WARNING: CPU: 1 PID: 8858 at fs/nfsd/nfs4state.c:1550 nfs4_free_ol_stateid+0xb0/0x100 [nfsd]
This patch, instead, frees the associated copynotify stateid here.
If the parent stateid is freed (without freeing the copynotify
stateids associated with it), it leads to the list corruption
when laundromat ends up freeing the copynotify state later.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: Fix kernel panic on partial unmap of a GPU VA region
This commit address a kernel panic issue that can happen if Userspace
tries to partially unmap a GPU virtual region (aka drm_gpuva).
The VM_BIND interface allows partial unmapping of a BO.
Panthor driver pre-allocates memory for the new drm_gpuva structures
that would be needed for the map/unmap operation, done using drm_gpuvm
layer. It expected that only one new drm_gpuva would be needed on umap
but a partial unmap can require 2 new drm_gpuva and that's why it
ended up doing a NULL pointer dereference causing a kernel panic.
Following dump was seen when partial unmap was exercised.
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000078

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: camss: Clean up received buffers on failed start of streaming
It is required to return the received buffers, if streaming can not be
started. For instance media_pipeline_start() may fail with EPIPE, if
a link validation between entities is not passed, and in such a case
a user gets a kernel warning:
WARNING: CPU: 1 PID: 520 at drivers/media/common/videobuf2/videobuf2-core.c:1592 vb2_start_streaming+0xec/0x160
<snip>
Call trace:
vb2_start_streaming+0xec/0x160
vb2_core_streamon+0x9c/0x1a0
vb2_ioctl_streamon+0x68/0xbc
v4l_streamon+0x30/0x3c

video_usercopy+0x37c/0x7b0
video_ioctl2+0x24/0x40
v4l2_ioctl+0x4c/0x70
The fix is to correct the error path in video_start_streaming() of camss.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ipv4: fix one memleak in __inet_del_ifa()
I got the below warning when do fuzzing test:
unregister_netdevice: waiting for bond0 to become free. Usage count = 2
It can be repoduced via:
ip link add bond0 type bond
sysctl -w net.ipv4.conf.bond0.promote_secondaries=1
ip addr add 4.117.174.103/0 scope 0x40 dev bond0
ip addr add 192.168.100.111/255.255.255.254 scope 0 dev bond0
ip addr add 0.0.0.4/0 scope 0x40 secondary dev bond0
ip addr del 4.117.174.103/0 scope 0x40 dev bond0
ip link delete bond0 type bond
In this reproduction test case, an incorrect 'last_prim' is found in
__inet_del_ifa(), as a result, the secondary address(0.0.0.4/0 scope 0x40)
is lost. The memory of the secondary address is leaked and the reference of
in_device and net_device is leaked.
Fix this problem:
Look for 'last_prim' starting at location of the deleted IP and inserting
the promoted IP into the location of 'last_prim'.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix hard lockup when reading the rx_monitor from debugfs
During I/O and simultaneous cat of /sys/kernel/debug/lpfc/fnX/rx_monitor, a
hard lockup similar to the call trace below may occur.
The spin_lock_bh in lpfc_rx_monitor_report is not protecting from timer
interrupts as expected, so change the strength of the spin lock to _irq.
Kernel panic - not syncing: Hard LOCKUP

Summary
In the Linux kernel, the following vulnerability has been resolved:
regulator: core: fix unbalanced of node refcount in regulator_dev_lookup()
I got the the following report:
OF: ERROR: memory leak, expected refcount 1 instead of 2,
of_node_get()/of_node_put() unbalanced - destroy cset entry:
attach overlay node /i2c/pmic@62/regulators/exten
In of_get_regulator(), the node is returned from of_parse_phandle()
with refcount incremented, after using it, of_node_put() need be called.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: Avoid use-after-free in dbg for hci_remove_adv_monitor()
KASAN reports that there's a use-after-free in
hci_remove_adv_monitor(). Trawling through the disassembly, you can
see that the complaint is from the access in bt_dev_dbg() under the
HCI_ADV_MONITOR_EXT_MSFT case. The problem case happens because
msft_remove_monitor() can end up freeing the monitor
structure. Specifically:
hci_remove_adv_monitor() ->
msft_remove_monitor() ->
msft_remove_monitor_sync() ->
msft_le_cancel_monitor_advertisement_cb() ->
hci_free_adv_monitor()
Let's fix the problem by just stashing the relevant data when it's
still valid.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: cdns3: gadget: Use-after-free during failed initialization and exit of cdnsp gadget
In the __cdnsp_gadget_init() and cdnsp_gadget_exit() functions, the gadget
structure (pdev->gadget) was freed before its endpoints.
The endpoints are linked via the ep_list in the gadget structure.
Freeing the gadget first leaves dangling pointers in the endpoint list.
When the endpoints are subsequently freed, this results in a use-after-free.
Fix:
By separating the usb_del_gadget_udc() operation into distinct "del" and
"put" steps, cdnsp_gadget_free_endpoints() can be executed prior to the
final release of the gadget structure with usb_put_gadget().
A patch similar to bb9c74a5bd14("usb: dwc3: gadget: Free gadget structure
only after freeing endpoints").

Summary
In the Linux kernel, the following vulnerability has been resolved:
mt76: mt7921: don't assume adequate headroom for SDIO headers
mt7921_usb_sdio_tx_prepare_skb() calls mt7921_usb_sdio_write_txwi() and
mt7921_skb_add_usb_sdio_hdr(), both of which blindly assume that
adequate headroom will be available in the passed skb. This assumption
typically is satisfied when the skb was allocated in the net core for
transmission via the mt7921 netdev (although even that is only an
optimization and is not strictly guaranteed), but the assumption is
sometimes not satisfied when the skb originated in the receive path of
another netdev and was passed through to the mt7921, such as by the
bridge layer. Blindly prepending bytes to an skb is always wrong.
This commit introduces a call to skb_cow_head() before the call to
mt7921_usb_sdio_write_txwi() in mt7921_usb_sdio_tx_prepare_skb() to
ensure that at least MT_SDIO_TXD_SIZE + MT_SDIO_HDR_SIZE bytes can be
pushed onto the skb.
Without this fix, I can trivially cause kernel panics by bridging an
MT7921AU-based USB 802.11ax interface with an Ethernet interface on an
Intel Atom-based x86 system using its onboard RTL8169 PCI Ethernet
adapter and also on an ARM-based Raspberry Pi 1 using its onboard
SMSC9512 USB Ethernet adapter. Note that the panics do not occur in
every system configuration, as they occur only if the receiving netdev
leaves less headroom in its received skbs than the mt7921 needs for its
SDIO headers.
Here is an example stack trace of this panic on Raspberry Pi OS Lite
2023-02-21 running kernel 6.1.24+ [1]:
skb_panic from skb_push+0x44/0x48
skb_push from mt7921_usb_sdio_tx_prepare_skb+0xd4/0x190 [mt7921_common]
mt7921_usb_sdio_tx_prepare_skb [mt7921_common] from mt76u_tx_queue_skb+0x94/0x1d0 [mt76_usb]

mt76_txq_schedule.part.0 [mt76] from mt76_txq_schedule_all+0x24/0x30 [mt76]
mt76_txq_schedule_all [mt76] from mt7921_tx_worker+0x58/0xf4 [mt7921_common]
mt7921_tx_worker [mt7921_common] from __mt76_worker_fn+0x9c/0xec [mt76]
__mt76_worker_fn [mt76] from kthread+0xbc/0xe0
kthread from ret_from_fork+0x14/0x34
After this fix, bridging the mt7921 interface works fine on both of my
previously problematic systems.

This assumption\ntypically is satisfied when the skb was allocated in the net core for\ntransmission via the mt7921 netdev (although even that is only an\noptimization and is not strictly guaranteed), but the assumption is\nsometimes not satisfied when the skb originated in the receive path of\nanother netdev and was passed through to the mt7921, such as by the\nbridge layer. Blindly prepending bytes to an skb is always wrong.\n\nThis commit introduces a call to skb_cow_head() before the call to\nmt7921_usb_sdio_write_txwi() in mt7921_usb_sdio_tx_prepare_skb() to\nensure that at least MT_SDIO_TXD_SIZE + MT_SDIO_HDR_SIZE bytes can be\npushed onto the skb.\n\nWithout this fix, I can trivially cause kernel panics by bridging an\nMT7921AU-based USB 802.11ax interface with an Ethernet interface on an\nIntel Atom-based x86 system using its onboard RTL8169 PCI Ethernet\nadapter and also on an ARM-based Raspberry Pi 1 using its onboard\nSMSC9512 USB Ethernet adapter. Note that the panics do not occur in\nevery system configuration, as they occur only if the receiving netdev\nleaves less headroom in its received skbs than the mt7921 needs for its\nSDIO headers.\n\nHere is an example stack trace of this panic on Raspberry Pi OS Lite\n2023-02-21 running kernel 6.1.24+ [1]:\n\n skb_panic from skb_push+0x44/0x48\n skb_push from mt7921_usb_sdio_tx_prepare_skb+0xd4/0x190 [mt7921_common]\n mt7921_usb_sdio_tx_prepare_skb [mt7921_common] from mt76u_tx_queue_skb+0x94/0x1d0 [mt76_usb]\n mt76u_tx_queue_skb [mt76_usb] from __mt76_tx_queue_skb+0x4c/0xc8 [mt76]\n __mt76_tx_queue_skb [mt76] from mt76_txq_schedule.part.0+0x13c/0x398 [mt76]\n mt76_txq_schedule.part.0 [mt76] from mt76_txq_schedule_all+0x24/0x30 [mt76]\n mt76_txq_schedule_all [mt76] from mt7921_tx_worker+0x58/0xf4 [mt7921_common]\n mt7921_tx_worker [mt7921_common] from __mt76_worker_fn+0x9c/0xec [mt76]\n __mt76_worker_fn [mt76] from kthread+0xbc/0xe0\n kthread from ret_from_fork+0x14/0x34\n\nAfter this fix, bridging the mt7921 interface works fine on both of my\npreviously problematic systems.\n\n[1] https://github.com/raspberrypi/firmware/tree/5c276f55a4b21345cd4d6200a504ee991851ff7a"

Summary
In the Linux kernel, the following vulnerability has been resolved:
igb: clean up in all error paths when enabling SR-IOV
After commit 50f303496d92 ("igb: Enable SR-IOV after reinit"), removing
the igb module could hang or crash (depending on the machine) when the
module has been loaded with the max_vfs parameter set to some value != 0.
In case of one test machine with a dual port 82580, this hang occurred:

The reproducer was a simple script:
#!/bin/sh
for i in `seq 1 5`; do
modprobe -rv igb
modprobe -v igb max_vfs=1
sleep 1
modprobe -rv igb
done
It turned out that this could only be reproduce on 82580 (quad and
dual-port), but not on 82576, i350 and i210. Further debugging showed
that igb_enable_sriov()'s call to pci_enable_sriov() is failing, because
dev->is_physfn is 0 on 82580.
Prior to commit 50f303496d92 ("igb: Enable SR-IOV after reinit"),
igb_enable_sriov() jumped into the "err_out" cleanup branch. After this
commit it only returned the error code.
So the cleanup didn't take place, and the incorrect VF setup in the
igb_adapter structure fooled the igb driver into assuming that VFs have
been set up where no VF actually existed.
Fix this problem by cleaning up again if pci_enable_sriov() fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Devcom, fix error flow in mlx5_devcom_register_device
In case devcom allocation is failed, mlx5 is always freeing the priv.
However, this priv might have been allocated by a different thread,
and freeing it might lead to use-after-free bugs.
Fix it by freeing the priv only in case it was allocated by the
running thread.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7921s: fix slab-out-of-bounds access in sdio host
SDIO may need addtional 511 bytes to align bus operation. If the tailroom
of this skb is not big enough, we would access invalid memory region.
For low level operation, increase skb size to keep valid memory access in
SDIO host.

Summary
In the Linux kernel, the following vulnerability has been resolved:
md: fix warning for holder mismatch from export_rdev()
Commit a1d767191096 ("md: use mddev->external to select holder in
export_rdev()") fix the problem that 'claim_rdev' is used for
blkdev_get_by_dev() while 'rdev' is used for blkdev_put().
However, if mddev->external is changed from 0 to 1, then 'rdev' is used
for blkdev_get_by_dev() while 'claim_rdev' is used for blkdev_put(). And
this problem can be reporduced reliably by following:
New file: mdadm/tests/23rdev-lifetime
devname=${dev0##*/}
devt=`cat /sys/block/$devname/dev`
pid=""
runtime=2
clean_up_test() {
pill -9 $pid
echo clear > /sys/block/md0/md/array_state
}
trap 'clean_up_test' EXIT
add_by_sysfs() {
while true; do
echo $devt > /sys/block/md0/md/new_dev
done
}
remove_by_sysfs(){
while true; do
echo remove > /sys/block/md0/md/dev-${devname}/state
done
}
echo md0 > /sys/module/md_mod/parameters/new_array || die "create md0 failed"
add_by_sysfs &
pid="$pid $!"
remove_by_sysfs &
pid="$pid $!"
sleep $runtime
exit 0

mm/hugetlb: fix huge_pmd_unshare() vs GUP-fast race
huge_pmd_unshare() drops a reference on a page table that may have
previously been shared across processes, potentially turning it into a
normal page table used in another process in which unrelated VMAs can
afterwards be installed.
If this happens in the middle of a concurrent gup_fast(), gup_fast() could
end up walking the page tables of another process. While I don't see any
way in which that immediately leads to kernel memory corruption, it is
really weird and unexpected.
Fix it with an explicit broadcast IPI through tlb_remove_table_sync_one(),
just like we do in khugepaged when removing page tables for a THP
collapse.

There is no network-facing path into mm/hugetlb.c.\nAC:L - The attacker controls every participant: one thread issues the GUP-fast pin, a sibling thread issues the unmap that calls huge_pmd_unshare(), and a second attacker process reuses the now-exclusively-owned PMD table, and the whole sequence can be looped indefinitely. The gup_fast() IRQ-disabled window can additionally be widened by requesting a full PUD-sized pin range, since the PUD is latched once at the start of gup_fast_pud_range() while the PMD loop then walks 512 entries.\nPR:L - hugetlb_file_setup() performs no capable() check for MAP_HUGETLB anonymous mappings, and none of huge_pmd_unshare()\u0027s callers or the GUP-fast entry points require any capability, so an ordinary local user account suffices. Only a configured hugepage pool is needed, which is standard on cloud, virtualization, DPDK and database hosts.\nUI:N - Exploitation is fully self-contained \u2014 the attacker forks its own second process to establish PMD sharing and to repurpose the unshared page table. No victim action is required at any point.\nS:U - The defect and its impact are both within the kernel\u0027s own memory-management security authority, with no VM, IOMMU or sandbox boundary crossed. This is a standard kernel memory-safety/privilege-escalation shape, so scope remains Unchanged.\nC:H - A gup_fast() walker that latched the stale PUD proceeds to walk a PMD table that now backs a different process\u0027s address space, pinning and returning struct pages that belong to that other mm. Handing those pages to O_DIRECT or vmsplice yields a direct read primitive against another process\u0027s memory, which on hosts where a hugetlbfs segment is shared across trust boundaries (QEMU/vhost-user, DPDK/SPDK, shared DB segments) discloses privileged data.\nI:H - The same stale walk with FOLL_WRITE returns writable pins on pages mapped by the foreign address space, so an O_DIRECT read or io_uring write into that buffer modifies another process\u0027s memory arbitrarily. It also leaves DMA pins and page reference/mapcount state established behind the back of the owning mm, corrupting page-table and pinning invariants the kernel relies on.\nA:H - GUP-fast traversing page tables of an unrelated address space while that process is concurrently tearing down and re-populating them is exactly the unsynchronized page-table access the kernel elsewhere prevents with tlb_remove_table_sync_one(), and it readily produces inconsistent refcount/mapcount state, VM_WARN/BUG trips, and oops in mm paths. The race can be re-armed in a loop by an unprivileged process."

Summary
In the Linux kernel, the following vulnerability has been resolved:
most: usb: Fix use-after-free in hdm_disconnect
hdm_disconnect() calls most_deregister_interface(), which eventually
unregisters the MOST interface device with device_unregister(iface->dev).
If that drops the last reference, the device core may call release_mdev()
immediately while hdm_disconnect() is still executing.
The old code also freed several mdev-owned allocations in
hdm_disconnect() and then performed additional put_device() calls.
Depending on refcount order, this could lead to use-after-free or
double-free when release_mdev() ran (or when unregister paths also
performed puts).
Fix by moving the frees of mdev-owned allocations into release_mdev(),
so they happen exactly once when the device is truly released, and by
dropping the extra put_device() calls in hdm_disconnect() that are
redundant after device_unregister() and most_deregister_interface().
This addresses the KASAN slab-use-after-free reported by syzbot in
hdm_disconnect(). See report and stack traces in the bug link below.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlx5: fix skb leak while fifo resync and push
During ptp resync operation SKBs were poped from the fifo but were never
freed neither by napi_consume nor by dev_kfree_skb_any. Add call to
napi_consume_skb to properly free SKBs.
Another leak was happening because mlx5e_skb_fifo_has_room() had an error
in the check. Comparing free running counters works well unless C promotes
the types to something wider than the counter. In this case counters are
u16 but the result of the substraction is promouted to int and it causes
wrong result (negative value) of the check when producer have already
overlapped but consumer haven't yet. Explicit cast to u16 fixes the issue.

A remote peer cannot set SKBTX_HW_TSTAMP on the host\u0027s outbound skbs, so the reliable trigger is a local syscall path, not received network data.\nAC:L - Both preconditions are entirely under the attacker\u0027s control: the u16 producer counter is advanced by the attacker\u0027s own packets, so wrapping into the broken-comparison window is deterministic after ~65536 sends, and outrunning the slower port-timestamp CQ is achieved by simply bursting traffic. No race the attacker cannot drive, no unpredictable memory layout, and the enabling tx_port_ts priv-flag is a routine runtime setting in PTP-timestamping deployments rather than a rare build option.\nPR:L - Neither setsockopt(SO_TIMESTAMPING) with SOF_TIMESTAMPING_TX_HARDWARE nor sending UDP to port 319 requires any capability, and mlx5e_use_ptpsq() checks only the skb tx_flags and packet classification \u2014 no hwtstamp or privilege gate. Any unprivileged local account can therefore drive skbs onto the PTP SQ and overflow the fifo.\nUI:N - The attacker\u0027s own packet transmission drives the fifo overflow and the corrupted TS-CQE consumption entirely; no action by any other user or administrator is needed once the interface is in its normal PTP configuration.\nS:U - The corruption is confined to kernel heap objects (sk_buff slab entries and the driver\u0027s skb fifo) within the same kernel security authority. There is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - Duplicate pops make the TS-CQ path dereference already-freed sk_buffs \u2014 mlx5e_skb_cb_get_hwts() reads freed slab memory and skb_tstamp_tx() clones the freed (and possibly reallocated) skb and delivers it to a socket\u0027s error queue, exposing kernel heap contents to userspace. The premature-free primitive is also the classic basis for a controlled arbitrary-read via heap spraying.\nI:H - The same duplicate consumption causes skb refcount underflow and double free of a kmem_cache object, corrupting the slab freelist, while mlx5e_skb_cb_hwtstamp_handler() writes hwtstamp values and memsets into the freed object\u0027s cb field. That combination of double-free plus write-into-freed-memory is a heap corruption primitive usable for control-flow hijack.\nA:H - The overflow reliably produces kernel oopses in softirq/NAPI context \u2014 NULL dereference on never-written kvzalloc\u0027d fifo slots during the resync loop, WARN_ON_ONCE in mlx5e_skb_fifo_pop() (fatal under panic_on_warn), and double-free BUGs \u2014 taking down the machine. Independently, the unfreed skbs in the resync path leak memory without bound until OOM."

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI/IOV: Fix race between SR-IOV enable/disable and hotplug
Commit 05703271c3cd ("PCI/IOV: Add PCI rescan-remove locking when
enabling/disabling SR-IOV") tried to fix a race between the VF removal
inside sriov_del_vfs() and concurrent hot unplug by taking the PCI
rescan/remove lock in sriov_del_vfs(). Similarly the PCI rescan/remove lock
was also taken in sriov_add_vfs() to protect addition of VFs.
This approach however causes deadlock on trying to remove PFs with SR-IOV
enabled because PFs disable SR-IOV during removal and this removal happens
under the PCI rescan/remove lock. So the original fix had to be reverted.
Instead of taking the PCI rescan/remove lock in sriov_add_vfs() and
sriov_del_vfs(), fix the race that occurs with SR-IOV enable and disable vs
hotplug higher up in the callchain by taking the lock in
sriov_numvfs_store() before calling into the driver's sriov_configure()
callback.

Similarly the PCI rescan/remove lock\nwas also taken in sriov_add_vfs() to protect addition of VFs.\n\nThis approach however causes deadlock on trying to remove PFs with SR-IOV\nenabled because PFs disable SR-IOV during removal and this removal happens\nunder the PCI rescan/remove lock. So the original fix had to be reverted.\n\nInstead of taking the PCI rescan/remove lock in sriov_add_vfs() and\nsriov_del_vfs(), fix the race that occurs with SR-IOV enable and disable vs\nhotplug higher up in the callchain by taking the lock in\nsriov_numvfs_store() before calling into the driver\u0027s sriov_configure()\ncallback."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath10k: add peer map clean up for peer delete in ath10k_sta_state()
When peer delete failed in a disconnect operation, use-after-free
detected by KFENCE in below log. It is because for each vdev_id and
address, it has only one struct ath10k_peer, it is allocated in
ath10k_peer_map_event(). When connected to an AP, it has more than
one HTT_T2H_MSG_TYPE_PEER_MAP reported from firmware, then the
array peer_map of struct ath10k will be set muti-elements to the
same ath10k_peer in ath10k_peer_map_event(). When peer delete failed
in ath10k_sta_state(), the ath10k_peer will be free for the 1st peer
id in array peer_map of struct ath10k, and then use-after-free happened
for the 2nd peer id because they map to the same ath10k_peer.
And clean up all peers in array peer_map for the ath10k_peer, then
user-after-free disappeared

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/iommu: Fix notifiers being shared by PCI and VIO buses
fail_iommu_setup() registers the fail_iommu_bus_notifier struct to both
PCI and VIO buses. struct notifier_block is a linked list node, so this
causes any notifiers later registered to either bus type to also be
registered to the other since they share the same node.
This causes issues in (at least) the vgaarb code, which registers a
notifier for PCI buses. pci_notify() ends up being called on a vio
device, converted with to_pci_dev() even though it's not a PCI device,
and finally makes a bad access in vga_arbiter_add_pci_device() as
discovered with KASAN:
BUG: KASAN: slab-out-of-bounds in vga_arbiter_add_pci_device+0x60/0xe00

Fix this by creating separate notifier_block structs for each bus type.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: pegasus-notetaker - fix potential out-of-bounds access
In the pegasus_notetaker driver, the pegasus_probe() function allocates
the URB transfer buffer using the wMaxPacketSize value from
the endpoint descriptor. An attacker can use a malicious USB descriptor
to force the allocation of a very small buffer.
Subsequently, if the device sends an interrupt packet with a specific
pattern (e.g., where the first byte is 0x80 or 0x42),
the pegasus_parse_packet() function parses the packet without checking
the allocated buffer size. This leads to an out-of-bounds memory access.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: Intel: avs: Do not share the name pointer between components
By sharing 'name' directly, tearing down components may lead to
use-after-free errors. Duplicate the name to avoid that.
At the same time, update the order of operations - since commit
cee28113db17 ("ASoC: dmaengine_pcm: Allow passing component name via
config") the framework does not override component->name if set before
invoking the initializer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: bridge: fix use-after-free due to MST port state bypass
syzbot reported[1] a use-after-free when deleting an expired fdb. It is
due to a race condition between learning still happening and a port being
deleted, after all its fdbs have been flushed. The port's state has been
toggled to disabled so no learning should happen at that time, but if we
have MST enabled, it will bypass the port's state, that together with VLAN
filtering disabled can lead to fdb learning at a time when it shouldn't
happen while the port is being deleted. VLAN filtering must be disabled
because we flush the port VLANs when it's being deleted which will stop
learning. This fix adds a check for the port's vlan group which is
initialized to NULL when the port is getting deleted, that avoids the port
state bypass. When MST is enabled there would be a minimal new overhead
in the fast-path because the port's vlan group pointer is cache-hot.

Summary
In the Linux kernel, the following vulnerability has been resolved:
smc: Use __sk_dst_get() and dst_dev_rcu() in in smc_clc_prfx_set().
smc_clc_prfx_set() is called during connect() and not under RCU
nor RTNL.
Using sk_dst_get(sk)->dev could trigger UAF.
Let's use __sk_dst_get() and dev_dst_rcu() under rcu_read_lock()
after kernel_getsockname().
Note that the returned value of smc_clc_prfx_set() is not used
in the caller.
While at it, we change the 1st arg of smc_clc_prfx_set[46]_rcu()
not to touch dst there.

"0 `blockdev --getsize /dev/ram0` flakey /dev/ram0 0 0 1 2 corrupt_bio_byte 512"
Fix the crash by checking if arg_name is non-NULL before comparing it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: firewire-motu: fix buffer overflow in hwdep read for DSP events
The DSP event handling code in hwdep_read() could write more bytes to
the user buffer than requested, when a user provides a buffer smaller
than the event header size (8 bytes).
Fix by using min_t() to clamp the copy size, This ensures we never copy
more than the user requested.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: adc: ina2xx: avoid NULL pointer dereference on OF device match
The affected lines were resulting in a NULL pointer dereference on our
platform because the device tree contained the following list of
compatible strings:
power-sensor@40 {
compatible = "ti,ina232", "ti,ina231";
...
};
Since the driver doesn't declare a compatible string "ti,ina232", the OF
matching succeeds on "ti,ina231". But the I2C device ID info is
populated via the first compatible string, cf. modalias population in
of_i2c_get_board_info(). Since there is no "ina232" entry in the legacy
I2C device ID table either, the struct i2c_device_id *id pointer in the
probe function is NULL.
Fix this by using the already populated type variable instead, which
points to the proper driver data. Since the name is also wanted, add a
generic one to the ina2xx_config table.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: rndis_host: Secure rndis_query check against int overflow
Variables off and len typed as uint32 in rndis_query function
are controlled by incoming RNDIS response message thus their
value may be manipulated. Setting off to a unexpectetly large
value will cause the sum with len and 8 to overflow and pass
the implemented validation step. Consequently the response
pointer will be referring to a location past the expected
buffer boundaries allowing information leakage e.g. via
RNDIS_OID_802_3_PERMANENT_ADDRESS OID.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/tegra: Add call to put_pid()
Add a call to put_pid() corresponding to get_task_pid().
host1x_memory_context_alloc() does not take ownership of the PID so we
need to free it here to avoid leaking.

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_ffa: Check if ffa_driver remove is present before executing
Currently ffa_drv->remove() is called unconditionally from
ffa_device_remove(). Since the driver registration doesn't check for it
and allows it to be registered without .remove callback, we need to check
for the presence of it before executing it from ffa_device_remove() to
above a NULL pointer dereference like the one below:
| Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-core: Fix a potential resource leak in v4l2_fwnode_parse_link()
If fwnode_graph_get_remote_endpoint() fails, 'fwnode' is known to be NULL,
so fwnode_handle_put() is a no-op.
Release the reference taken from a previous fwnode_graph_get_port_parent()
call instead.
Also handle fwnode_graph_get_port_parent() failures.
In order to fix these issues, add an error handling path to the function
and the needed gotos.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: use hdev->workqueue when queuing hdev->{cmd,ncmd}_timer works
syzbot is reporting attempt to schedule hdev->cmd_work work from system_wq
WQ into hdev->workqueue WQ which is under draining operation [1], for
commit c8efcc2589464ac7 ("workqueue: allow chained queueing during
destruction") does not allow such operation.
The check introduced by commit 877afadad2dce8aa ("Bluetooth: When HCI work
queue is drained, only queue chained work") was incomplete.
Use hdev->workqueue WQ when queuing hdev->{cmd,ncmd}_timer works because
hci_{cmd,ncmd}_timeout() calls queue_work(hdev->workqueue). Also, protect
the queuing operation with RCU read lock in order to avoid calling
queue_delayed_work() after cancel_delayed_work() completed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: s390: pv: fix index value of replaced ASCE
The index field of the struct page corresponding to a guest ASCE should
be 0. When replacing the ASCE in s390_replace_asce(), the index of the
new ASCE should also be set to 0.
Having the wrong index might lead to the wrong addresses being passed
around when notifying pte invalidations, and eventually to validity
intercepts (VM crash) if the prefix gets unmapped and the notifier gets
called with the wrong address.

Summary
In the Linux kernel, the following vulnerability has been resolved:
accel/habanalabs: support mapping cb with vmalloc-backed coherent memory
When IOMMU is enabled, dma_alloc_coherent() with GFP_USER may return
addresses from the vmalloc range. If such an address is mapped without
VM_MIXEDMAP, vm_insert_page() will trigger a BUG_ON due to the
VM_PFNMAP restriction.
Fix this by checking for vmalloc addresses and setting VM_MIXEDMAP
in the VMA before mapping. This ensures safe mapping and avoids kernel
crashes. The memory is still driver-allocated and cannot be accessed
directly by userspace.

Summary
In the Linux kernel, the following vulnerability has been resolved:
orangefs: Fix kmemleak in orangefs_prepare_debugfs_help_string()
When insert and remove the orangefs module, then debug_help_string will
be leaked:
unreferenced object 0xffff8881652ba000 (size 4096):

Summary
In the Linux kernel, the following vulnerability has been resolved:
exfat: use kvmalloc_array/kvfree instead of kmalloc_array/kfree
The call stack shown below is a scenario in the Linux 4.19 kernel.
Allocating memory failed where exfat fs use kmalloc_array due to
system memory fragmentation, while the u-disk was inserted without
recognition.
Devices such as u-disk using the exfat file system are pluggable and
may be insert into the system at any time.
However, long-term running systems cannot guarantee the continuity of
physical memory. Therefore, it's necessary to address this issue.
Binder:2632_6: page allocation failure: order:4,
mode:0x6040c0(GFP_KERNEL|__GFP_COMP), nodemask=(null)

[242178.097681] el0_svc+0x8/0x340
By analyzing the exfat code,we found that continuous physical memory
is not required here,so kvmalloc_array is used can solve this problem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm flakey: don't corrupt the zero page
When we need to zero some range on a block device, the function
__blkdev_issue_zero_pages submits a write bio with the bio vector pointing
to the zero page. If we use dm-flakey with corrupt bio writes option, it
will corrupt the content of the zero page which results in crashes of
various userspace programs. Glibc assumes that memory returned by mmap is
zeroed and it uses it for calloc implementation; if the newly mapped
memory is not zeroed, calloc will return non-zeroed memory.
Fix this bug by testing if the page is equal to ZERO_PAGE(0) and
avoiding the corruption in this case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/sev: Make enc_dec_hypercall() accept a size instead of npages
enc_dec_hypercall() accepted a page count instead of a size, which
forced its callers to round up. As a result, non-page aligned
vaddrs caused pages to be spuriously marked as decrypted via the
encryption status hypercall, which in turn caused consistent
corruption of pages during live migration. Live migration requires
accurate encryption status information to avoid migrating pages
from the wrong perspective.

The party that triggers the damaging step (live migration) controls it completely.\nPR:N - No privileges of any kind are required inside the guest \u2014 the wrong encryption status is registered during early boot and the corruption lands during a routine, guest-transparent live migration. In the SEV threat model the untrusted hypervisor needs no guest credentials to reach this state.\nUI:N - Live migration is transparent to the guest and requires no action by any guest user; the mis-declaration itself happens automatically at boot.\nS:C - The guest kernel bug corrupts state held by a different security authority \u2014 the hypervisor\u0027s page-encryption-status list \u2014 causing memory protected by the SEV/AMD-SP confidential-computing boundary to be handled by the host as shared. The impact therefore crosses the guest/host CoCo boundary rather than staying within the guest\u0027s own authority.\nC:H - Pages containing guest-private kernel data are declared shared to the untrusted hypervisor, so they are handled outside the SEV-protected migration path (raw-copied across the migration channel rather than PSP-wrapped) and the host treats them as memory it may freely read. Wholesale corruption of kernel percpu pages is also leverageable toward disclosure.\nI:H - The commit documents consistent corruption of entire guest kernel pages during live migration, and the mis-marked private pages are additionally exposed to host writes as \"shared\" memory \u2014 a direct integrity break of guest-private memory.\nA:H - The corrupted pages sit in the kernel percpu region adjacent to `apf_reason`/`steal_time`/`kvm_apic_eoi`; consuming pseudorandom garbage there after migration reliably leads to kernel oops/panic and an unusable guest."

In the Linux kernel, the following vulnerability has been resolved:
tty: serial: imx: disable Ageing Timer interrupt request irq
There maybe pending USR interrupt before requesting irq, however
uart_add_one_port has not executed, so there will be kernel panic:

[ 0.872283] lr : imx_uart_int+0xf8/0x1ec
The issue only happends in the inmate linux when Jailhouse hypervisor
enabled. The test procedure is:
while true; do
jailhouse enable imx8mp.cell
jailhouse cell linux xxxx
sleep 10
jailhouse cell destroy 1
jailhouse disable
sleep 5
done
And during the upper test, press keys to the 2nd linux console.
When `jailhouse cell destroy 1`, the 2nd linux has no chance to put
the uart to a quiese state, so USR1/2 may has pending interrupts. Then
when `jailhosue cell linux xx` to start 2nd linux again, the issue
trigger.
In order to disable irqs before requesting them, both UCR1 and UCR2 irqs
should be disabled, so here fix that, disable the Ageing Timer interrupt
in UCR2 as UCR1 does.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipu3-imgu: Fix NULL pointer dereference in imgu_subdev_set_selection()
Calling v4l2_subdev_get_try_crop() and v4l2_subdev_get_try_compose()
with a subdev state of NULL leads to a NULL pointer dereference. This
can currently happen in imgu_subdev_set_selection() when the state
passed in is NULL, as this method first gets pointers to both the "try"
and "active" states and only then decides which to use.
The same issue has been addressed for imgu_subdev_get_selection() with
commit 30d03a0de650 ("ipu3-imgu: Fix NULL pointer dereference in active
selection access"). However the issue still persists in
imgu_subdev_set_selection().
Therefore, apply a similar fix as done in the aforementioned commit to
imgu_subdev_set_selection(). To keep things a bit cleaner, introduce
helper functions for "crop" and "compose" access and use them in both
imgu_subdev_set_selection() and imgu_subdev_get_selection().

The root cause is, inodeA references inodeB via inodeB's ino, once inodeA
is truncated, it calls truncate_dnode() to truncate data blocks in inodeB's
node page, it traverse mapping data from node->i.i_addr[0] to
node->i.i_addr[ADDRS_PER_BLOCK() - 1], result in out-of-boundary access.
This patch fixes to add sanity check on dnode page in truncate_dnode(),
so that, it can help to avoid triggering such issue, and once it encounters
such issue, it will record newly introduced ERROR_INVALID_NODE_REFERENCE
error into superblock, later fsck can detect such issue and try repairing.
Also, it removes f2fs_truncate_data_blocks() for cleanup due to the
function has only one caller, and uses f2fs_truncate_data_blocks_range()
instead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Shutdown FW DMA in bnxt_shutdown()
The netif_close() call in bnxt_shutdown() only stops packet DMA. There
may be FW DMA for trace logging (recently added) that will continue. If
we kexec to a new kernel, the DMA will corrupt memory in the new kernel.
Add bnxt_hwrm_func_drv_unrgtr() to unregister the driver from the FW.
This will stop the FW DMA. In case the call fails, call pcie_flr() to
reset the function and stop the DMA.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: alcor: fix return value check of mmc_add_host()
mmc_add_host() may return error, if we ignore its return value, the memory
that allocated in mmc_alloc_host() will be leaked and it will lead a kernel
crash because of deleting not added device in the remove path.
So fix this by checking the return value and calling mmc_free_host() in the
error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
apparmor: Fix memleak in alloc_ns()
After changes in commit a1bd627b46d1 ("apparmor: share profile name on
replacement"), the hname member of struct aa_policy is not valid slab
object, but a subset of that, it can not be freed by kfree_sensitive(),

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: hif_usb: Fix use-after-free in ath9k_hif_usb_reg_in_cb()
It is possible that skb is freed in ath9k_htc_rx_msg(), then
usb_submit_urb() fails and we try to free skb again. It causes
use-after-free bug. Moreover, if alloc_skb() fails, urb->context becomes
NULL but rx_buf is not freed and there can be a memory leak.
The patch removes unnecessary nskb and makes skb processing more clear: it
is supposed that ath9k_htc_rx_msg() either frees old skb or passes its
managing to another callback function.
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix potential memory leaks at error path for UMP open
The allocation and initialization errors at alloc_midi_urbs() that is
called at MIDI 2.0 / UMP device are supposed to be handled at the
caller side by invoking free_midi_urbs(). However, free_midi_urbs()
loops only for ep->num_urbs entries, and since ep->num_entries wasn't
updated yet at the allocation / init error in alloc_midi_urbs(), this
entry won't be released.
The intention of free_midi_urbs() is to release the whole elements, so
change the loop size to NUM_URBS to scan over all elements for fixing
the missed releases.
Also, the call of free_midi_urbs() is missing at
snd_usb_midi_v2_open(). Although it'll be released later at
reopen/close or disconnection, it's better to release immediately at
the error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/radeon: delete radeon_fence_process in is_signaled, no deadlock
Delete the attempt to progress the queue when checking if fence is
signaled. This avoids deadlock.
dma-fence_ops::signaled can be called with the fence lock in unknown
state. For radeon, the fence lock is also the wait queue lock. This can
cause a self deadlock when signaled() tries to make forward progress on
the wait queue. But advancing the queue is unneeded because incorrectly
returning false from signaled() is perfectly acceptable.
(cherry picked from commit 527ba26e50ec2ca2be9c7c82f3ad42998a75d0db)

Race Condition Analysis:
The race occurs between kprobe activation and perf_events initialization:
CPU0 CPU1
==== ====
perf_kprobe_init
perf_trace_event_init
tp_event->perf_events = list;(1)
tp_event->class->reg (2)← KPROBE ACTIVE
Debug exception triggers
...
kprobe_dispatcher
kprobe_perf_func (tk->tp.flags & TP_FLAG_PROFILE)
head = this_cpu_ptr(call->perf_events)(3)
(perf_events is still NULL)
Problem:
1. CPU0 executes (1) assigning tp_event->perf_events = list
2. CPU0 executes (2) enabling kprobe functionality via class->reg()
3. CPU1 triggers and reaches kprobe_dispatcher
4. CPU1 checks TP_FLAG_PROFILE - condition passes (step 2 completed)
5. CPU1 calls kprobe_perf_func() and crashes at (3) because
call->perf_events is still NULL
CPU1 sees that kprobe functionality is enabled but does not see that
perf_events has been assigned.

Summary
In the Linux kernel, the following vulnerability has been resolved:
most: usb: hdm_probe: Fix calling put_device() before device initialization
The early error path in hdm_probe() can jump to err_free_mdev before
&mdev->dev has been initialized with device_initialize(). Calling
put_device(&mdev->dev) there triggers a device core WARN and ends up
invoking kref_put(&kobj->kref, kobject_release) on an uninitialized
kobject.
In this path the private struct was only kmalloc'ed and the intended
release is effectively kfree(mdev) anyway, so free it directly instead
of calling put_device() on an uninitialized device.
This removes the WARNING and fixes the pre-initialization error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: refresh inline data size before write operations
The cached ei->i_inline_size can become stale between the initial size
check and when ext4_update_inline_data()/ext4_create_inline_data() use
it. Although ext4_get_max_inline_size() reads the correct value at the
time of the check, concurrent xattr operations can modify i_inline_size
before ext4_write_lock_xattr() is acquired.
This causes ext4_update_inline_data() and ext4_create_inline_data() to
work with stale capacity values, leading to a BUG_ON() crash in
ext4_write_inline_data():
kernel BUG at fs/ext4/inline.c:1331!
BUG_ON(pos + len > EXT4_I(inode)->i_inline_size);
The race window:
1. ext4_get_max_inline_size() reads i_inline_size = 60 (correct)
2. Size check passes for 50-byte write
3. [Another thread adds xattr, i_inline_size changes to 40]
4. ext4_write_lock_xattr() acquires lock
5. ext4_update_inline_data() uses stale i_inline_size = 60
6. Attempts to write 50 bytes but only 40 bytes actually available
7. BUG_ON() triggers
Fix this by recalculating i_inline_size via ext4_find_inline_data_nolock()
immediately after acquiring xattr_sem. This ensures ext4_update_inline_data()
and ext4_create_inline_data() work with current values that are protected
from concurrent modifications.
This is similar to commit a54c4613dac1 ("ext4: fix race writing to an
inline_data file while its xattrs are changing") which fixed i_inline_off
staleness. This patch addresses the related i_inline_size staleness issue.

Although ext4_get_max_inline_size() reads the correct value at the\ntime of the check, concurrent xattr operations can modify i_inline_size\nbefore ext4_write_lock_xattr() is acquired.\n\nThis causes ext4_update_inline_data() and ext4_create_inline_data() to\nwork with stale capacity values, leading to a BUG_ON() crash in\next4_write_inline_data():\n\n kernel BUG at fs/ext4/inline.c:1331!\n BUG_ON(pos + len \u003e EXT4_I(inode)-\u003ei_inline_size);\n\nThe race window:\n1. ext4_get_max_inline_size() reads i_inline_size = 60 (correct)\n2.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix inode leak in ext4_xattr_inode_create() on an error path
There is issue as follows when do setxattr with inject fault:
[localhost]# fsck.ext4 -fn /dev/sda
e2fsck 1.46.6-rc1 (12-Sep-2022)
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Unattached zero-length inode 15. Clear? no
Unattached inode 15
Connect to /lost+found? no
Pass 5: Checking group summary information
/dev/sda: ********** WARNING: Filesystem still has errors **********
/dev/sda: 15/655360 files (0.0% non-contiguous), 66755/2621440 blocks
This occurs in 'ext4_xattr_inode_create()'. If 'ext4_mark_inode_dirty()'
fails, dropping i_nlink of the inode is needed. Or will lead to inode leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
devlink: rate: Unset parent pointer in devl_rate_nodes_destroy
The function devl_rate_nodes_destroy is documented to "Unset parent for
all rate objects". However, it was only calling the driver-specific
`rate_leaf_parent_set` or `rate_node_parent_set` ops and decrementing
the parent's refcount, without actually setting the
`devlink_rate->parent` pointer to NULL.
This leaves a dangling pointer in the `devlink_rate` struct, which cause
refcount error in netdevsim[1] and mlx5[2]. In addition, this is
inconsistent with the behavior of `devlink_nl_rate_parent_node_set`,
where the parent pointer is correctly cleared.
This patch fixes the issue by explicitly setting `devlink_rate->parent`
to NULL after notifying the driver, thus fulfilling the function's
documented behavior for all rate objects.

"value": "AV:L - The dangling `devlink_rate-\u003eparent` is dereferenced from the devlink generic-netlink interface (`DEVLINK_CMD_RATE_GET` dump) and from local device/eswitch reconfiguration paths reached via netlink and sysfs. No network packet processing is involved, so this is local-only.\nAC:L - Once `devl_rate_nodes_destroy()` runs (SR-IOV teardown, eswitch mode change, driver reload \u2014 routine in SR-IOV/DPU cloud hosts), the stale parent pointer persists in surviving leaf rate objects, so there is no race to win: the attacker sprays the 120-byte kmalloc-128 slot and then deterministically triggers the deref with an unprivileged `devlink port function rate show`. The reproducers in the commit message are deterministic one-shot command sequences.\nPR:L - The vulnerable dereference sites \u2014 `devlink_nl_rate_fill()` reading `devlink_rate-\u003eparent-\u003ename` and emitting it to userspace \u2014 sit behind `DEVLINK_CMD_RATE_GET`, which carries only `GENL_CMD_CAP_DO|DUMP` with no `GENL_ADMIN_PERM` and no family-level gate, so an ordinary unprivileged local user reaches the freed object and obtains the read primitive. Only the state-creating teardown needs CAP_NET_ADMIN, and that occurs as routine orchestration activity on the affected mlx5/ice/netdevsim hosts.\nUI:N - No victim must open a file, mount a filesystem, or interact in any way; the attacker issues the netlink dump (or the whole command sequence) themselves. Exploitation completes entirely within attacker-issued syscalls.\nS:U - The use-after-free read and write are confined to kernel slab memory under the same security authority as the kernel itself. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - `nla_put_string(msg, DEVLINK_ATTR_RATE_PARENT_NODE_NAME, devlink_rate-\u003eparent-\u003ename)` loads a pointer from offset 64 of the freed `struct devlink_rate` and copies the string it points at back to userspace; after reclaiming the kmalloc-128 slot with controlled data this is an unbounded arbitrary kernel-memory read delivered over an unprivileged netlink dump.\nI:H - `devl_rate_leaf_destroy()` performs `refcount_dec()` on offset 72 of the freed object, giving a controlled decrement primitive against whatever kmalloc-128 object reclaims the slot \u2014 dropping a live object\u0027s refcount to zero yields a second use-after-free and the standard heap-spray path to arbitrary write and control-flow hijack.\nA:H - Even without reclamation the bug reliably produces `refcount_warn_saturate` WARNINGs (\"decrement hit 0; leaking memory\") as shown in both netdevsim and mlx5 traces, which panic the box under `panic_on_warn`; with a reclaimed slot the corrupted refcount causes premature frees, slab corruption, and oops on the subsequent dangling-pointer string dereference."

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix warning when putting transaction with qgroups enabled after abort
If we have a transaction abort with qgroups enabled we get a warning
triggered when doing the final put on the transaction, like this:

[552.6832] ---[ end trace 0000000000000000 ]---
This corresponds to this line of code:
void btrfs_put_transaction(struct btrfs_transaction *transaction)
{
(...)
WARN_ON(!RB_EMPTY_ROOT(
&transaction->delayed_refs.dirty_extent_root));
(...)
}
The warning happens because btrfs_qgroup_destroy_extent_records(), called
in the transaction abort path, we free all entries from the rbtree
"dirty_extent_root" with rbtree_postorder_for_each_entry_safe(), but we
don't actually empty the rbtree - it's still pointing to nodes that were
freed.
So set the rbtree's root node to NULL to avoid this warning (assign
RB_ROOT).

Summary
In the Linux kernel, the following vulnerability has been resolved:
platform/x86: intel: punit_ipc: fix memory corruption
This passes the address of the pointer "&punit_ipcdev" when the intent
was to pass the pointer itself "punit_ipcdev" (without the ampersand).
This means that the:
complete(&ipcdev->cmd_complete);
in intel_punit_ioc() will write to a wrong memory address corrupting it.

No namespace-specific capability is required.\nUI:N - Exploitation requires only the attacker\u0027s own file operation and completed mailbox interrupt, without action by another user.\nS:U - The corruption occurs within the host kernel and compromises resources governed by that same kernel security authority; it does not inherently cross a VM, IOMMU, or separate sandbox boundary.\nC:H - The bogus completion accesses unrelated global storage and follows invalid wait-list and task pointers. Exploitation of the resulting kernel-memory corruption can provide kernel execution and unrestricted access to confidential memory.\nI:H - complete() increments unrelated memory and mutates a bogus spinlock and wait list; wake and list-deletion operations can produce further attacker-influenced kernel writes and control-flow compromise.\nA:H - The bogus lock and list operations can cause an oops, panic, or hard lockup, while the real completion remains unsignaled. A single or repeatedly issued command can therefore deny system availability."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: pcm: Fix potential data race at PCM memory allocation helpers
The PCM memory allocation helpers have a sanity check against too many
buffer allocations. However, the check is performed without a proper
lock and the allocation isn't serialized; this allows user to allocate
more memories than predefined max size.
Practically seen, this isn't really a big problem, as it's more or
less some "soft limit" as a sanity check, and it's not possible to
allocate unlimitedly. But it's still better to address this for more
consistent behavior.
The patch covers the size check in do_alloc_pages() with the
card->memory_mutex, and increases the allocated size there for
preventing the further overflow. When the actual allocation fails,
the size is decreased accordingly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: hidraw: fix data race on device refcount
The hidraw_open() function increments the hidraw device reference
counter. The counter has no dedicated synchronization mechanism,
resulting in a potential data race when concurrently opening a device.
The race is a regression introduced by commit 8590222e4b02 ("HID:
hidraw: Replace hidraw device table mutex with a rwsem"). While
minors_rwsem is intended to protect the hidraw_table itself, by instead
acquiring the lock for writing, the reference counter is also protected.
This is symmetrical to hidraw_release().

The race is known to trigger accidentally during normal FIDO2 device probing (systemd issue #27947), and HID hot-unplug/Bluetooth-link-loss events needed to convert the refcount skew into a free are routine and inducible.\nPR:L - An unprivileged local user needs only read access to a hidraw node; systemd\u0027s uaccess/seat udev rules grant the logged-in user an ACL on hidraw devices for FIDO2 tokens, hardware wallets, 3D mice and game controllers (empirically confirmed: `crw-rw----+` with `user:\u003cuid\u003e:rw-`). No capability, no root, no ioctl gate.\nUI:N - The attacker\u0027s own threads perform every step of the attack; no victim action is required. Device detach events occur spontaneously (Bluetooth link loss, dongle removal, uhid teardown) or can be caused by the attacker themselves.\nS:U - The refcount corruption and resulting use-after-free are confined to kernel memory within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - The premature `kfree(struct hidraw)` leaves `list-\u003ehidraw` dangling, and `hidraw_read()` dereferences `list-\u003ehidraw-\u003eexist` and the embedded wait queue on reclaimed memory; a UAF on a small kmalloc object with attacker-sprayed contents yields an arbitrary-read primitive and kernel memory disclosure.\nI:H - `add_wait_queue()`/`remove_wait_queue()` on the freed `hidraw-\u003ewait` write list pointers into reclaimed heap memory, and a sprayed replacement object gives attacker-controlled `list_head` pointers plus a controlled `wait_queue_entry-\u003efunc` call \u2014 an arbitrary write and control-flow hijack. The stale-minor path also corrupts a different, live `struct hidraw`\u0027s refcount.\nA:H - `hidraw_release()` on the orphaned fd dereferences a NULL `hidraw_table[minor]` for a guaranteed oops, and the UAF crashes the kernel outright; additionally the refcount underflow permanently leaks hidraw minors (only 64 exist), denying hidraw registration to all future HID devices."

fbdev: udlfb: Fix endpoint check
The syzbot fuzzer detected a problem in the udlfb driver, caused by an
endpoint not having the expected type:
usb 1-1: Read EDID byte 0 failed: -71
usb 1-1: Unable to get valid EDID from device/display
------------[ cut here ]------------
usb 1-1: BOGUS urb xfer, pipe 3 != type 1

The current approach for this issue failed to catch the problem
because it only checks for the existence of a bulk-OUT endpoint; it
doesn't check whether this endpoint is the one that the driver will
actually use.
We can fix the problem by instead checking that the endpoint used by
the driver does exist and is bulk-OUT.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vdpa_sim: fix possible memory leak in vdpasim_net_init() and vdpasim_blk_init()
Inject fault while probing module, if device_register() fails in
vdpasim_net_init() or vdpasim_blk_init(), but the refcount of kobject is
not decreased to 0, the name allocated in dev_set_name() is leaked.
Fix this by calling put_device(), so that name can be freed in
callback function kobject_cleanup().

Summary
In the Linux kernel, the following vulnerability has been resolved:
auxdisplay: hd44780: Fix potential memory leak in hd44780_remove()
hd44780_probe() allocates a memory chunk for hd with kzalloc() and
makes "lcd->drvdata->hd44780" point to it. When we call hd44780_remove(),
we should release all relevant memory and resource. But "lcd->drvdata
->hd44780" is not released, which will lead to a memory leak.
We should release the "lcd->drvdata->hd44780" in hd44780_remove() to fix
the memory leak bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
remoteproc: pru: Fix potential NULL pointer dereference in pru_rproc_set_ctable()
pru_rproc_set_ctable() accessed rproc->priv before the IS_ERR_OR_NULL
check, which could lead to a null pointer dereference. Move the pru
assignment, ensuring we never dereference a NULL rproc pointer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: 6lowpan: reset link-local header on ipv6 recv path
Bluetooth 6lowpan.c netdev has header_ops, so it must set link-local
header for RX skb, otherwise things crash, eg. with AF_PACKET SOCK_RAW
Add missing skb_reset_mac_header() for uncompressed ipv6 RX path.
For the compressed one, it is done in lowpan_header_decompress().
Log: (BlueZ 6lowpan-tester Client Recv Raw - Success)

The problem was caused by the fact that the driver does not check
whether the endpoints it uses are actually present and have the
appropriate types. This can be fixed by adding a simple check of
the endpoints.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: Add bounds checking in bit_putcs to fix vmalloc-out-of-bounds
Add bounds checking to prevent writes past framebuffer boundaries when
rendering text near screen edges. Return early if the Y position is off-screen
and clip image height to screen boundary. Break from the rendering loop if the
X position is off-screen. When clipping image width to fit the screen, update
the character count to match the clipped width to prevent buffer size
mismatches.
Without the character count update, bit_putcs_aligned and bit_putcs_unaligned
receive mismatched parameters where the buffer is allocated for the clipped
width but cnt reflects the original larger count, causing out-of-bounds writes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: ISO: fix iso_conn related locking and validity issues
sk->sk_state indicates whether iso_pi(sk)->conn is valid. Operations
that check/update sk_state and access conn should hold lock_sock,
otherwise they can race.
The order of taking locks is hci_dev_lock > lock_sock > iso_conn_lock,
which is how it is in connect/disconnect_cfm -> iso_conn_del ->
iso_chan_del.
Fix locking in iso_connect_cis/bis and sendmsg/recvmsg to take lock_sock
around updating sk_state and conn.
iso_conn_del must not occur during iso_connect_cis/bis, as it frees the
iso_conn. Hold hdev->lock longer to prevent that.
This should not reintroduce the issue fixed in commit 241f51931c35
("Bluetooth: ISO: Avoid circular locking dependency"), since the we
acquire locks in order. We retain the fix in iso_sock_connect to release
lock_sock before iso_connect_* acquires hdev->lock.
Similarly for commit 6a5ad251b7cd ("Bluetooth: ISO: Fix possible
circular locking dependency"). We retain the fix in iso_conn_ready to
not acquire iso_conn_lock before lock_sock.
iso_conn_add shall return iso_conn with valid hcon. Make it so also when
reusing an old CIS connection waiting for disconnect timeout (see
__iso_sock_close where conn->hcon is set to NULL).

This makes the race deterministic rather than dependent on timing luck.\nPR:N - No local account and no privileges are needed \u2014 the sending side is the kernel\u0027s own RFCOMM session or a system Bluetooth daemon, and L2CAP/LE CoC channels at BT_SECURITY_LOW accept connections without pairing or authentication. The attacker is purely an unauthenticated adjacent device.\nUI:N - Exploitation needs only a connectable/discoverable target or an already-established profile connection; the freed-conn dereference happens entirely within normal send and link-teardown handling. No victim action is required.\nS:U - The corruption and its consequences are confined to the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary. This is a standard in-kernel memory-safety issue.\nC:H - This is a use-after-free read of a freed `struct l2cap_conn` slab object whose contents the attacker can influence by reclaiming the slot with heap spray, and the value read (`conn-\u003emtu`) feeds fragment sizing and copy loops. UAF of an attacker-groomable object is treated as enabling arbitrary read.\nI:H - The dangling `l2cap_conn` is used to drive skb allocation and fragmentation while the freed slab is attacker-reclaimable, giving heap-grooming leverage over subsequent kernel allocations and control-flow-relevant state. Per kernel guidance a use-after-free is scored as exploitable for arbitrary write/control-flow hijack.\nA:H - The freed-object read reliably oopses under any hardening (KASAN/slab poisoning) and, when the reclaimed `conn-\u003emtu` reads as 0, `count` becomes 0 so `len` never decreases \u2014 an infinite skb-allocation loop causing hang and memory exhaustion. Either outcome is a full denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: fix blktrace debugfs entries leakage
Commit 99d055b4fd4b ("block: remove per-disk debugfs files in
blk_unregister_queue") moves blk_trace_shutdown() from
blk_release_queue() to blk_unregister_queue(), this is safe if blktrace
is created through sysfs, however, there is a regression in corner
case.
blktrace can still be enabled after del_gendisk() through ioctl if
the disk is opened before del_gendisk(), and if blktrace is not shutdown
through ioctl before closing the disk, debugfs entries will be leaked.
Fix this problem by shutdown blktrace in disk_release(), this is safe
because blk_trace_remove() is reentrant.

The triggering condition (`get_current_pin_assignments()` returning 0) is deterministic for the attached partner and was hit by real production hardware.\nPR:L - The attribute is created with `DEVICE_ATTR_RW` (mode 0644) and the affected versions have no `is_visible` callback, so any unprivileged local account can read it with no capability, namespace, or group membership required.\nUI:N - Exploitation needs only the attacker\u0027s own `read()` syscall against a persistently present sysfs file; no victim must open, mount, or configure anything. On ChromeOS/Android the same read is additionally performed automatically by system daemons on partner registration.\nS:U - The corruption is kernel heap memory damaged by kernel code, confined to the kernel\u0027s own security authority with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The write corrupts the final byte of an adjacent, attacker-groomable 4K slab object; overwriting a length, count, or index field in a neighboring structure converts this into out-of-bounds reads and kernel memory disclosure. Per kernel scoring guidance, heap memory corruption leveragable for information disclosure is scored High.\nI:H - This is a genuine heap out-of-bounds write (`buf[-1] = \u0027\\n\u0027`) into a neighboring slab allocation the attacker can select via heap grooming; single-byte heap overflows of this class have historically been escalated to arbitrary write and privilege escalation. Out-of-bounds writes are scored High.\nA:H - The originating report is a kernel fault \u2014 an arm64 MTE tag-check fault taken in `pin_assignment_show()` leading to an oops \u2014 and KASAN builds panic on the same access. On production kernels the silent corruption of an adjacent 4K slab object causes crashes, and the trigger can be repeated indefinitely by an unprivileged user."

Summary
In the Linux kernel, the following vulnerability has been resolved:
amdgpu: validate offset_in_bo of drm_amdgpu_gem_va
This is motivated by OOB access in amdgpu_vm_update_range when
offset_in_bo+map_size overflows.
v2: keep the validations in amdgpu_vm_bo_map
v3: add the validations to amdgpu_vm_bo_map/amdgpu_vm_bo_replace_map
rather than to amdgpu_gem_va_ioctl

"value": "AV:L - The vulnerability is reached through the `DRM_IOCTL_AMDGPU_GEM_VA` ioctl on a local DRM device node (`/dev/dri/renderD*` or `card*`), requiring local system access. There is no network-facing path to `amdgpu_vm_bo_map()`.\nAC:L - A single ioctl with an attacker-chosen page-aligned `offset_in_bo` near 2^64 deterministically wraps the `offset + size` bounds check; there is no race, no timing window, and no dependence on memory layout the attacker cannot influence. The OOB index is fully attacker-controlled, so the target of the wild access can be aimed rather than guessed.\nPR:L - The ioctl is registered `DRM_AUTH|DRM_RENDER_ALLOW`, so any unprivileged local user with access to the render node can invoke it \u2014 this includes members of the render/video group, any user with a logind graphical session, containers with GPU passthrough, and sandboxed processes such as browser GPU processes. No root or capability is required.\nUI:N - The attacker performs GEM object creation and the malicious `AMDGPU_VA_OP_MAP`/`AMDGPU_VA_OP_REPLACE` ioctl entirely on its own; no victim action or cooperation is needed.\nS:U - The vulnerable amdgpu driver code and the corrupted kernel memory are within the same security authority (the host kernel). This is standard local kernel compromise rather than a VM or IOMMU boundary escape.\nC:H - The overflowed offset produces an OOB read `pages_addr[cursor.start \u003e\u003e PAGE_SHIFT]` at an attacker-chosen index spanning up to 2^55 bytes past the DMA-address array, and the value read becomes the physical address in a GPU page table entry, letting the attacker\u0027s GPU context read arbitrary physical memory. The TT node-walk path additionally performs unbounded OOB reads of kernel heap data.\nI:H - Because the OOB-read value is installed as a GPU PTE physical address, the attacker\u0027s own GPU commands gain DMA write access to arbitrary physical memory, giving a full arbitrary-write primitive suitable for kernel code/credential modification. Attacker-controlled page table entries also corrupt the VM state itself.\nA:H - The same input reliably produces kernel crashes \u2014 wild pointer dereference in the `node++` mm_nodes walk, a reachable `BUG_ON(start + size \u003e res-\u003esize)`, and an effectively unbounded VRAM block-walk loop executed while holding `vm-\u003eeviction_lock` with BOs reserved, causing a soft lockup/hang. Any of these panics or wedges the GPU and the system."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qedi: Fix use after free bug in qedi_remove()
In qedi_probe() we call __qedi_probe() which initializes
&qedi->recovery_work with qedi_recovery_handler() and
&qedi->board_disable_work with qedi_board_disable_work().
When qedi_schedule_recovery_handler() is called, schedule_delayed_work()
will finally start the work.
In qedi_remove(), which is called to remove the driver, the following
sequence may be observed:
Fix this by finishing the work before cleanup in qedi_remove().

Cancel recovery_work and board_disable_work in __qedi_remove().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ima: Handle error code returned by ima_filter_rule_match()
In ima_match_rules(), if ima_filter_rule_match() returns -ENOENT due to
the rule being NULL, the function incorrectly skips the 'if (!rc)' check
and sets 'result = true'. The LSM rule is considered a match, causing
extra files to be measured by IMA.
This issue can be reproduced in the following scenario:
After unloading the SELinux policy module via 'semodule -d', if an IMA
measurement is triggered before ima_lsm_rules is updated,
in ima_match_rules(), the first call to ima_filter_rule_match() returns
-ESTALE. This causes the code to enter the 'if (rc == -ESTALE &&
!rule_reinitialized)' block, perform ima_lsm_copy_rule() and retry. In
ima_lsm_copy_rule(), since the SELinux module has been removed, the rule
becomes NULL, and the second call to ima_filter_rule_match() returns
-ENOENT. This bypasses the 'if (!rc)' check and results in a false match.

Fix this by changing 'if (!rc)' to 'if (rc <= 0)' to ensure that error
codes like -ENOENT do not bypass the check and accidentally result in a
successful match.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7921: fix skb leak by txs missing in AMSDU
txs may be dropped if the frame is aggregated in AMSDU. When the problem
shows up, some SKBs would be hold in driver to cause network stopped
temporarily. Even if the problem can be recovered by txs timeout handling,
mt7921 still need to disable txs in AMSDU to avoid this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Fix memory leak in kfd_mem_dmamap_userptr()
If the number of pages from the userptr BO differs from the SG BO then the
allocated memory for the SG table doesn't get freed before returning
-EINVAL, which may lead to a memory leak in some error paths. Fix this by
checking the number of pages before allocating memory for the SG table.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sock: Prevent race in socket write iter and sock bind
There is a potential race condition between sock bind and socket write
iter. bind may free the same cmd via mgmt_pending before write iter sends
the cmd, just as syzbot reported in UAF[1].
Here we use hci_dev_lock to synchronize the two, thereby avoiding the
UAF mentioned in [1].
[1]
syzbot reported:

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - fix DMA transfer direction
When CONFIG_DMA_API_DEBUG is selected, while running the crypto self
test on the QAT crypto algorithms, the function add_dma_entry() reports
a warning similar to the one below, saying that overlapping mappings
are not supported. This occurs in tests where the input and the output
scatter list point to the same buffers (i.e. two different scatter lists
which point to the same chunks of memory).
The logic that implements the mapping uses the flag DMA_BIDIRECTIONAL
for both the input and the output scatter lists which leads to
overlapped write mappings. These are not supported by the DMA layer.
Fix by specifying the correct DMA transfer directions when mapping
buffers. For in-place operations where the input scatter list
matches the output scatter list, buffers are mapped once with
DMA_BIDIRECTIONAL, otherwise input buffers are mapped using the flag
DMA_TO_DEVICE and output buffers are mapped with DMA_FROM_DEVICE.
Overlapping a read mapping with a write mapping is a valid case in
dma-coherent devices like QAT.
The function that frees and unmaps the buffers, qat_alg_free_bufl()
has been changed accordingly to the changes to the mapping function.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sched: act_connmark: initialize struct tc_ife to fix kernel leak
In tcf_connmark_dump(), the variable 'opt' was partially initialized using a
designatied initializer. While the padding bytes are reamined
uninitialized. nla_put() copies the entire structure into a
netlink message, these uninitialized bytes leaked to userspace.
Initialize the structure with memset before assigning its fields
to ensure all members and padding are cleared prior to beign copied.

Summary
In the Linux kernel, the following vulnerability has been resolved:
of: overlay: Call of_changeset_init() early
When of_overlay_fdt_apply() fails, the changeset may be partially
applied, and the caller is still expected to call of_overlay_remove() to
clean up this partial state.
However, of_overlay_apply() calls of_resolve_phandles() before
init_overlay_changeset(). Hence if the overlay fails to apply due to an
unresolved symbol, the overlay_changeset.cset.entries list is still
uninitialized, and cleanup will crash with a NULL-pointer dereference in
overlay_removal_is_ok().
Fix this by moving the call to of_changeset_init() from
init_overlay_changeset() to of_overlay_fdt_apply(), where all other
early initialization is done.

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix infinite loop in nilfs_mdt_get_block()
If the disk image that nilfs2 mounts is corrupted and a virtual block
address obtained by block lookup for a metadata file is invalid,
nilfs_bmap_lookup_at_level() may return the same internal return code as
-ENOENT, meaning the block does not exist in the metadata file.
This duplication of return codes confuses nilfs_mdt_get_block(), causing
it to read and create a metadata block indefinitely.
In particular, if this happens to the inode metadata file, ifile,
semaphore i_rwsem can be left held, causing task hangs in lock_mount.
Fix this issue by making nilfs_bmap_lookup_at_level() treat virtual block
address translation failures with -ENOENT as metadata corruption instead
of returning the error code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: firewire-motu: add bounds check in put_user loop for DSP events
In the DSP event handling code, a put_user() loop copies event data.
When the user buffer size is not aligned to 4 bytes, it could overwrite
beyond the buffer boundary.
Fix by adding a bounds check before put_user().

Summary
In the Linux kernel, the following vulnerability has been resolved:
staging: media: tegra-video: fix device_node use after free
At probe time this code path is followed:
* tegra_csi_init
* tegra_csi_channels_alloc
* for_each_child_of_node(node, channel) -- iterates over channels
* automatically gets 'channel'
* tegra_csi_channel_alloc()
* saves into chan->of_node a pointer to the channel OF node
* automatically gets and puts 'channel'
* now the node saved in chan->of_node has refcount 0, can disappear
* tegra_csi_channels_init
* iterates over channels
* tegra_csi_channel_init -- uses chan->of_node
After that, chan->of_node keeps storing the node until the device is
removed.
of_node_get() the node and of_node_put() it during teardown to avoid any
risk.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix ioremap issues in lpfc_sli4_pci_mem_setup()
When if_type equals zero and pci_resource_start(pdev, PCI_64BIT_BAR4)
returns false, drbl_regs_memmap_p is not remapped. This passes a NULL
pointer to iounmap(), which can trigger a WARN() on certain arches.
When if_type equals six and pci_resource_start(pdev, PCI_64BIT_BAR4)
returns true, drbl_regs_memmap_p may has been remapped and
ctrl_regs_memmap_p is not remapped. This is a resource leak and passes a
NULL pointer to iounmap().
To fix these issues, we need to add null checks before iounmap(), and
change some goto labels.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/client: Fix memory leak in drm_client_target_cloned
dmt_mode is allocated and never freed in this function.
It was found with the ast driver, but most drivers using generic fbdev
setup are probably affected.
This fixes the following kmemleak report:

Summary
In the Linux kernel, the following vulnerability has been resolved:
gfs2: Fix unlikely race in gdlm_put_lock
In gdlm_put_lock(), there is a small window of time in which the
DFL_UNMOUNT flag has been set but the lockspace hasn't been released,
yet. In that window, dlm may still call gdlm_ast() and gdlm_bast().
To prevent it from dereferencing freed glock objects, only free the
glock if the lockspace has actually been released.

There is no network-facing service path into `gdlm_put_lock()`.\nAC:H - Exploitation requires winning a race whose opening the attacker does not control \u2014 `DFL_UNMOUNT` is set only by a root-driven umount or an error-driven withdraw \u2014 and additionally requires a DLM ast/bast for that exact resource to arrive after the free but before `dlm_release_lockspace()` completes, plus slab reuse after the RCU grace period. The author explicitly characterises it as an \"unlikely race\" in a \"small window of time\".\nPR:L - Once the teardown window is open (via administrator umount, cluster-manager failover, or a withdraw provoked by storage errors), an ordinary unprivileged user with access to the GFS2 mount drives the vulnerable side: normal file operations force glock disposal through `__gfs2_glock_put \u2192 lm_put_lock`, and creating inodes sprays `gfs2_glock_cachep` to groom the freed object. No capability check exists anywhere on that path.\nUI:N - The attacker only performs ordinary file operations on an already-mounted GFS2 filesystem; no victim must open a file, mount media, or take any deliberate action. The privileged unmount/withdraw is an environmental system state, accounted for in Attack Complexity rather than user interaction.\nS:U - The freed `struct gfs2_glock`, the DLM callback that writes into it, and any resulting corruption all live in the host kernel\u0027s own security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free on a slab object whose contents the attacker can groom by reallocating glocks, and `gdlm_ast()` reads `gl-\u003egl_flags`, `gl-\u003egl_dstamp`, `gl-\u003egl_name.ln_type` and the `gl-\u003egl_name.ln_sbd` pointer out of the freed memory before the dead-lockref guard, using `ln_sbd` as a dereference target \u2014 giving an attacker-steerable kernel read primitive.\nI:H - Three distinct writes hit the freed object: DLM\u0027s `lksb-\u003esb_status`/`sb_flags` stores, `clear_bit(GLF_BLOCKING, \u0026gl-\u003egl_flags)`, and `gfs2_update_stats(\u0026gl-\u003egl_stats, ...)`; worse, `this_cpu_ptr(gl-\u003egl_name.ln_sbd-\u003esd_lkstats)` turns a groomed pointer in the freed object into the destination of a read-modify-write, and a surviving lockref check leads into `gfs2_glock_complete()` and `gl-\u003egl_ops` indirect calls \u2014 a control-flow hijack path.\nA:H - Dereferencing a freed glock from the DLM callback workqueue produces KASAN splats, oopses on garbage `ln_sbd`/`gl_ops` pointers, and `BUG()` in `gdlm_bast()` on an unrecognised mode, panicking the node. On a clustered filesystem, crashing the node also triggers fencing and cluster-wide recovery."

Summary
In the Linux kernel, the following vulnerability has been resolved:
sched/psi: use kernfs polling functions for PSI trigger polling
Destroying psi trigger in cgroup_file_release causes UAF issues when
a cgroup is removed from under a polling process. This is happening
because cgroup removal causes a call to cgroup_file_release while the
actual file is still alive. Destroying the trigger at this point would
also destroy its waitqueue head and if there is still a polling process
on that file accessing the waitqueue, it will step on the freed pointer:
do_select
vfs_poll
do_rmdir
cgroup_rmdir
kernfs_drain_open_files
cgroup_file_release
cgroup_pressure_release
psi_trigger_destroy
wake_up_pollfree(&t->event_wait)
// vfs_poll is unblocked
synchronize_rcu
kfree(t)
poll_freewait -> UAF access to the trigger's waitqueue head
Patch [1] fixed this issue for epoll() case using wake_up_pollfree(),
however the same issue exists for synchronous poll() case.
The root cause of this issue is that the lifecycles of the psi trigger's
waitqueue and of the file associated with the trigger are different. Fix
this by using kernfs_generic_poll function when polling on cgroup-specific
psi triggers. It internally uses kernfs_open_node->poll waitqueue head
with its lifecycle tied to the file's lifecycle. This also renders the
fix in [1] obsolete, so revert it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/bridge: it6505: Initialize AUX channel in it6505_i2c_probe
During device boot, the HPD interrupt could be triggered before the DRM
subsystem registers it6505 as a DRM bridge. In such cases, the driver
tries to access AUX channel and causes NULL pointer dereference.
Initializing the AUX channel earlier to prevent such error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/rtas: avoid device tree lookups in rtas_os_term()
rtas_os_term() is called during panic. Its behavior depends on a couple
of conditions in the /rtas node of the device tree, the traversal of
which entails locking and local IRQ state changes. If the kernel panics
while devtree_lock is held, rtas_os_term() as currently written could
hang.
Instead of discovering the relevant characteristics at panic time,
cache them in file-static variables at boot. Note the lookup for
"ibm,extended-os-term" is converted to of_property_read_bool() since it
is a boolean property, not an RTAS function token.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tpm: tpm_vtpm_proxy: fix a race condition in /dev/vtpmx creation
/dev/vtpmx is made visible before 'workqueue' is initialized, which can
lead to a memory corruption in the worst case scenario.
Address this by initializing 'workqueue' as the very first step of the
driver initialization.

Fixed channels present on conn-\u003echan_l give a valid target CID without any local socket.\nUI:N - No victim action is needed \u2014 the packet is processed by hci_rx_work as soon as it arrives on a connectable/advertising host with Bluetooth enabled, which is the default on phones, cars, headsets and laptops.\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 handler reads chan-\u003escid and chan-\u003edcid out of the freed kmalloc-1k object and echoes them to the attacker in the Disconnect Response, giving a repeatable remote leak of reclaimed kernel heap contents, and the broader use-after-free permits arbitrary read via heap grooming.\nI:H - After the increment-on-zero the code performs three indirect calls (chan-\u003eops-\u003eset_shutdown, -\u003eteardown, -\u003eclose) through function pointers read from the freed object plus a list_del on freed list heads, so an attacker who sprays the reclaimed kmalloc-1024 slot obtains control-flow hijack and arbitrary-write primitives.\nA:H - The bug is a KASAN-confirmed use-after-free that mutex_locks freed memory and triggers a refcount_t \"increment on 0\" splat, reliably producing a kernel oops/panic, and it can be re-triggered remotely at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: mpi3mr: Fix missing mrioc->evtack_cmds initialization
Commit c1af985d27da ("scsi: mpi3mr: Add Event acknowledgment logic")
introduced an array mrioc->evtack_cmds but initialization of the array
elements was missed. They are just zero cleared. The function
mpi3mr_complete_evt_ack() refers host_tag field of the elements. Due to the
zero value of the host_tag field, the function calls clear_bit() for
mrico->evtack_cmds_bitmap with wrong bit index. This results in memory
access to invalid address and "BUG: KASAN: use-after-free". This BUG was
observed at eHBA-9600 firmware update to version 8.3.1.0. To fix it, add
the missing initialization of mrioc->evtack_cmds.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btusb: mediatek: Fix kernel crash when releasing mtk iso interface
When performing reset tests and encountering abnormal card drop issues
that lead to a kernel crash, it is necessary to perform a null check
before releasing resources to avoid attempting to release a null pointer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
keys: Fix linking a duplicate key to a keyring's assoc_array
When making a DNS query inside the kernel using dns_query(), the request
code can in rare cases end up creating a duplicate index key in the
assoc_array of the destination keyring. It is eventually found by
a BUG_ON() check in the assoc_array implementation and results in
a crash.
Example report:

The situation occurs as follows:
* Some kernel facility invokes dns_query() to resolve a hostname, for
example, "abcdef". The function registers its global DNS resolver
cache as current->cred.thread_keyring and passes the query to
request_key_net() -> request_key_tag() -> request_key_and_link().
* Function request_key_and_link() creates a keyring_search_context
object. Its match_data.cmp method gets set via a call to
type->match_preparse() (resolves to dns_resolver_match_preparse()) to
dns_resolver_cmp().
* Function request_key_and_link() continues and invokes
search_process_keyrings_rcu() which returns that a given key was not
found. The control is then passed to request_key_and_link() ->
construct_alloc_key().
* Concurrently to that, a second task similarly makes a DNS query for
"abcdef." and its result gets inserted into the DNS resolver cache.
* Back on the first task, function construct_alloc_key() first runs
__key_link_begin() to determine an assoc_array_edit operation to
insert a new key. Index keys in the array are compared exactly as-is,
using keyring_compare_object(). The operation

Summary
In the Linux kernel, the following vulnerability has been resolved:
xhci: dbc: Fix memory leak in xhci_alloc_dbc()
If DbC is already in use, then the allocated memory for the xhci_dbc struct
doesn't get freed before returning NULL, which leads to a memleak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: Fix dropping valid root bus resources with .end = zero
On r8a7791/koelsch:
kmemleak: 1 new suspected memory leaks (see /sys/kernel/debug/kmemleak)
# cat /sys/kernel/debug/kmemleak
unreferenced object 0xc3a34e00 (size 64):
comm "swapper/0", pid 1, jiffies 4294937460 (age 199.080s)
hex dump (first 32 bytes):
b4 5d 81 f0 b4 5d 81 f0 c0 b0 a2 c3 00 00 00 00 .]...]..........
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
backtrace:
[<fe3aa979>] __kmalloc+0xf0/0x140
[<34bd6bc0>] resource_list_create_entry+0x18/0x38
[<767046bc>] pci_add_resource_offset+0x20/0x68
[<b3f3edf2>] devm_of_pci_get_host_bridge_resources.constprop.0+0xb0/0x390
When coalescing two resources for a contiguous aperture, the second
resource is enlarged to cover the full contiguous range, while the first
resource is marked invalid. This invalidation is done by clearing the
flags, start, and end members.
When adding the initial resources to the bus later, invalid resources are
skipped. Unfortunately, the check for an invalid resource considers only
the end member, causing false positives.
E.g. on r8a7791/koelsch, root bus resource 0 ("bus 00") is skipped, and no
longer registered with pci_bus_insert_busn_res() (causing the memory leak),
nor printed:
pci-rcar-gen2 ee090000.pci: host bridge /soc/pci@ee090000 ranges:
pci-rcar-gen2 ee090000.pci: MEM 0x00ee080000..0x00ee08ffff -> 0x00ee080000
pci-rcar-gen2 ee090000.pci: PCI: revision 11
pci-rcar-gen2 ee090000.pci: PCI host bridge to bus 0000:00
-pci_bus 0000:00: root bus resource [bus 00]
pci_bus 0000:00: root bus resource [mem 0xee080000-0xee08ffff]
Fix this by only skipping resources where all of the flags, start, and end
members are zero.

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: imx93: fix memory leak and missing unwind goto in imx93_clocks_probe
In function probe(), it returns directly without unregistered hws
when error occurs.
Fix this by adding 'goto unregister_hws;' on line 295 and
line 310.
Use devm_kzalloc() instead of kzalloc() to automatically
free the memory using devm_kfree() when error occurs.
Replace of_iomap() with devm_of_iomap() to automatically
handle the unused ioremap region and delete 'iounmap(anatop_base);'
in unregister_hws.

Summary
In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8723bs: fix stack buffer overflow in OnAssocReq IE parsing
The Supported Rates IE length from an incoming Association Request frame
was used directly as the memcpy() length when copying into a fixed-size
16-byte stack buffer (supportRate). A malicious station can advertise an
IE length larger than 16 bytes, causing a stack buffer overflow.
Clamp ie_len to the buffer size before copying the Supported Rates IE,
and correct the bounds check when merging Extended Supported Rates to
prevent a second potential overflow.
This prevents kernel stack corruption triggered by malformed association
requests.

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: amba-pl011: avoid SBSA UART accessing DMACR register
Chapter "B Generic UART" in "ARM Server Base System Architecture" [1]
documentation describes a generic UART interface. Such generic UART
does not support DMA. In current code, sbsa_uart_pops and
amba_pl011_pops share the same stop_rx operation, which will invoke
pl011_dma_rx_stop, leading to an access of the DMACR register. This
commit adds a using_rx_dma check in pl011_dma_rx_stop to avoid the
access to DMACR register for SBSA UARTs which does not support DMA.
When the kernel enables DMA engine with "CONFIG_DMA_ENGINE=y", Linux
SBSA PL011 driver will access PL011 DMACR register in some functions.
For most real SBSA Pl011 hardware implementations, the DMACR write
behaviour will be ignored. So these DMACR operations will not cause
obvious problems. But for some virtual SBSA PL011 hardware, like Xen
virtual SBSA PL011 (vpl011) device, the behaviour might be different.
Xen vpl011 emulation will inject a data abort to guest, when guest is
accessing an unimplemented UART register. As Xen VPL011 is SBSA
compatible, it will not implement DMACR register. So when Linux SBSA
PL011 driver access DMACR register, it will get an unhandled data abort
fault and the application will get a segmentation fault:

This has been discussed in the Xen community, and we think it should fix
this in Linux. See [2] for more information.

The cause of the issue is that brelse() is called on both ofibh.sbh
and ofibh.ebh by udf_find_entry() when it returns NULL. However,
brelse() is called by udf_rename(), too. So, b_count on buffer_head
becomes unbalanced.
This patch fixes the issue by not calling brelse() by udf_rename()
when udf_find_entry() returns NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: core: Prevent invalid memory access when there is no parent
Commit 813665564b3d ("iio: core: Convert to use firmware node handle
instead of OF node") switched the kind of nodes to use for label
retrieval in device registration. Probably an unwanted change in that
commit was that if the device has no parent then NULL pointer is
accessed. This is what happens in the stock IIO dummy driver when a
new entry is created in configfs:
# mkdir /sys/kernel/config/iio/devices/dummy/foo
BUG: kernel NULL pointer dereference, address: ...
...
Call Trace:
__iio_device_register
iio_dummy_probe
Since there seems to be no reason to make a parent device of an IIO
dummy device mandatory, let’s prevent the invalid memory access in
__iio_device_register when the parent device is NULL. With this
change, the IIO dummy driver works fine with configfs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: dvb-usb: fix memory leak in dvb_usb_adapter_init()
Syzbot reports a memory leak in "dvb_usb_adapter_init()".
The leak is due to not accounting for and freeing current iteration's
adapter->priv in case of an error. Currently if an error occurs,
it will exit before incrementing "num_adapters_initalized",
which is used as a reference counter to free all adap->priv
in "dvb_usb_adapter_exit()". There are multiple error paths that
can exit from before incrementing the counter. Including the
error handling paths for "dvb_usb_adapter_stream_init()",
"dvb_usb_adapter_dvb_init()" and "dvb_usb_adapter_frontend_init()"
within "dvb_usb_adapter_init()".
This means that in case of an error in any of these functions the
current iteration is not accounted for and the current iteration's
adap->priv is not freed.
Fix this by freeing the current iteration's adap->priv in the
"stream_init_err:" label in the error path. The rest of the
(accounted for) adap->priv objects are freed in dvb_usb_adapter_exit()
as expected using the num_adapters_initalized variable.
Syzbot report:

Currently if an error occurs,\nit will exit before incrementing \"num_adapters_initalized\",\nwhich is used as a reference counter to free all adap-\u003epriv\nin \"dvb_usb_adapter_exit()\". There are multiple error paths that\ncan exit from before incrementing the counter. Including the\nerror handling paths for \"dvb_usb_adapter_stream_init()\",\n\"dvb_usb_adapter_dvb_init()\" and \"dvb_usb_adapter_frontend_init()\"\nwithin \"dvb_usb_adapter_init()\".\n\nThis means that in case of an error in any of these functions the\ncurrent iteration is not accounted for and the current iteration\u0027s\nadap-\u003epriv is not freed.\n\nFix this by freeing the current iteration\u0027s adap-\u003epriv in the\n\"stream_init_err:\" label in the error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tpm: tpm_tis: Add the missed acpi_put_table() to fix memory leak
In check_acpi_tpm2(), we get the TPM2 table just to make
sure the table is there, not used after the init, so the
acpi_put_table() should be added to release the ACPI memory.

Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring/rw: defer fsnotify calls to task context
We can't call these off the kiocb completion as that might be off
soft/hard irq context. Defer the calls to when we process the
task_work for this request. That avoids valid complaints like:
stack backtrace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: potential integer overflow in usbg_make_tpg()
The variable tpgt in usbg_make_tpg() is defined as unsigned long and is
assigned to tpgt->tport_tpgt, which is defined as u16. This may cause an
integer overflow when tpgt is greater than USHRT_MAX (65535). I
haven't tried to trigger it myself, but it is possible to trigger it
by calling usbg_make_tpg() with a large value for tpgt.
I modified the type of tpgt to match tpgt->tport_tpgt and adjusted the
relevant code accordingly.
This patch is similar to commit 59c816c1f24d ("vhost/scsi: potential
memory corruption").

Summary
In the Linux kernel, the following vulnerability has been resolved:
binfmt_misc: restore write access before closing files opened by open_exec()
bm_register_write() opens an executable file using open_exec(), which
internally calls do_open_execat() and denies write access on the file to
avoid modification while it is being executed.
However, when an error occurs, bm_register_write() closes the file using
filp_close() directly. This does not restore the write permission, which
may cause subsequent write operations on the same file to fail.
Fix this by calling exe_file_allow_write_access() before filp_close() to
restore the write permission properly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Fix null pointer dereference in bnxt_bs_trace_check_wrap()
With older FW, we may get the ASYNC_EVENT_CMPL_EVENT_ID_DBG_BUF_PRODUCER
for FW trace data type that has not been initialized. This will result
in a crash in bnxt_bs_trace_type_wrap(). Add a guard to check for a
valid magic_byte pointer before proceeding.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: client: fix memory leak in smb3_fs_context_parse_param
The user calls fsconfig twice, but when the program exits, free() only
frees ctx->source for the second fsconfig, not the first.
Regarding fc->source, there is no code in the fs context related to its
memory reclamation.
To fix this memory leak, release the source memory corresponding to ctx
or fc before each parsing.
syzbot reported:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: soc-compress: Reposition and add pcm_mutex
If panic_on_warn is set and compress stream(DPCM) is started,
then kernel panic occurred because card->pcm_mutex isn't held appropriately.
In the following functions, warning were issued at this line
"snd_soc_dpcm_mutex_assert_held".
static int dpcm_be_connect(struct snd_soc_pcm_runtime *fe,
struct snd_soc_pcm_runtime *be, int stream)
{
...
snd_soc_dpcm_mutex_assert_held(fe);
...
}
void dpcm_be_disconnect(struct snd_soc_pcm_runtime *fe, int stream)
{
...
snd_soc_dpcm_mutex_assert_held(fe);
...
}
void snd_soc_runtime_action(struct snd_soc_pcm_runtime *rtd,
int stream, int action)
{
...
snd_soc_dpcm_mutex_assert_held(rtd);
...
}
int dpcm_dapm_stream_event(struct snd_soc_pcm_runtime *fe, int dir,
int event)
{
...
snd_soc_dpcm_mutex_assert_held(fe);
...
}
These functions are called by soc_compr_set_params_fe, soc_compr_open_fe
and soc_compr_free_fe
without pcm_mutex locking. And this is call stack.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: Flush shmem writes before mapping buffers CPU-uncached
The shmem layer zeroes out the new pages using cached mappings, and if
we don't CPU-flush we might leave dirty cachelines behind, leading to
potential data leaks and/or asynchronous buffer corruption when dirty
cachelines are evicted.

No victim action or cooperation is required.\nS:U - The disclosure and corruption occur within the kernel/GPU-driver security authority acting on behalf of the calling process; no VM, IOMMU, or sandbox boundary is crossed by the flaw itself.\nC:H - Reads through the uncached mapping return residual physical DRAM contents from pages recycled by the buddy allocator, which may hold freed kernel data, page-cache contents, other processes\u0027 memory, or key material. The leak is unbounded in volume and arbitrarily repeatable by allocating large BOs in a loop, amounting to a general physical-memory disclosure primitive.\nI:L - Stale dirty cachelines are written back over data placed in the buffer through the uncached mapping, silently corrupting GPU command streams, descriptors, and compute results. The corruption is real and attacker-triggerable but is confined to the buffer\u0027s own pages and its content is not attacker-chosen, so it is not an arbitrary cross-domain write.\nA:H - A corrupted command stream raises CS_FATAL/CS_UNRECOVERABLE or a progress timeout, both of which call `panthor_device_schedule_reset()` and force a device-wide GPU reset that destroys every context on the system, not just the attacker\u0027s. On the phone, automotive, and embedded devices panthor targets, the GPU drives the display, so a locally repeatable reset storm denies graphics service to all users."

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/hyperv: Disable IBT when hypercall page lacks ENDBR instruction
On hardware that supports Indirect Branch Tracking (IBT), Hyper-V VMs
with ConfigVersion 9.3 or later support IBT in the guest. However,
current versions of Hyper-V have a bug in that there's not an ENDBR64
instruction at the beginning of the hypercall page. Since hypercalls are
made with an indirect call to the hypercall page, all hypercall attempts
fail with an exception and Linux panics.
A Hyper-V fix is in progress to add ENDBR64. But guard against the Linux
panic by clearing X86_FEATURE_IBT if the hypercall page doesn't start
with ENDBR. The VM will boot and run without IBT.
If future Linux 32-bit kernels were to support IBT, additional hypercall
page hackery would be needed to make IBT work for such kernels in a
Hyper-V VM.

Summary
In the Linux kernel, the following vulnerability has been resolved:
backlight: led-bl: Add devlink to supplier LEDs
LED Backlight is a consumer of one or multiple LED class devices, but
devlink is currently unable to create correct supplier-producer links when
the supplier is a class device. It creates instead a link where the
supplier is the parent of the expected device.
One consequence is that removal order is not correctly enforced.
Issues happen for example with the following sections in a device tree
overlay:
// An LED driver chip
pca9632@62 {
compatible = "nxp,pca9632";
reg = <0x62>;
// ...
addon_led_pwm: led-pwm@3 {
reg = <3>;
label = "addon:led:pwm";
};
};
backlight-addon {
compatible = "led-backlight";
leds = <&addon_led_pwm>;
brightness-levels = <255>;
default-brightness-level = <255>;
};
In this example, the devlink should be created between the backlight-addon
(consumer) and the pca9632@62 (supplier). Instead it is created between the
backlight-addon (consumer) and the parent of the pca9632@62, which is
typically the I2C bus adapter.
On removal of the above overlay, the LED driver can be removed before the
backlight device, resulting in:
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000010
...
Call trace:
led_put+0xe0/0x140
devm_led_release+0x6c/0x98
Another way to reproduce the bug without any device tree overlays is
unbinding the LED class device (pca9632@62) before unbinding the consumer
(backlight-addon):
echo 11-0062 >/sys/bus/i2c/drivers/leds-pca963x/unbind
echo ...backlight-dock >/sys/bus/platform/drivers/led-backlight/unbind
Fix by adding a devlink between the consuming led-backlight device and the
supplying LED device, as other drivers and subsystems do as well.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Fix oops in xe_gem_fault when running core_hotunplug test.
I saw an oops in xe_gem_fault when running the xe-fast-feedback
testlist against the realtime kernel without debug options enabled.
The panic happens after core_hotunplug unbind-rebind finishes.
Presumably what happens is that a process mmaps, unlocks because
of the FAULT_FLAG_RETRY_NOWAIT logic, has no process memory left,
causing ttm_bo_vm_dummy_page() to return VM_FAULT_NOPAGE, since
there was nothing left to populate, and then oopses in
"mem_type_is_vram(tbo->resource->mem_type)" because tbo->resource
is NULL.
It's convoluted, but fits the data and explains the oops after
the test exits.

Summary
In the Linux kernel, the following vulnerability has been resolved:
regulator: da9063: fix null pointer deref with partial DT config
When some of the da9063 regulators do not have corresponding DT nodes
a null pointer dereference occurs on boot because such regulators have
no init_data causing the pointers calculated in
da9063_check_xvp_constraints() to be invalid.
Do not dereference them in this case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
md/raid5-cache: fix a deadlock in r5l_exit_log()
Commit b13015af94cf ("md/raid5-cache: Clear conf->log after finishing
work") introduce a new problem:
// caller hold reconfig_mutex
r5l_exit_log
flush_work(&log->disable_writeback_work)
r5c_disable_writeback_async
wait_event
/*
* conf->log is not NULL, and mddev_trylock()
* will fail, wait_event() can never pass.
*/
conf->log = NULL
Fix this problem by setting 'config->log' to NULL before wake_up() as it
used to be, so that wait_event() from r5c_disable_writeback_async() can
exist. In the meantime, move forward md_unregister_thread() so that
null-ptr-deref this commit fixed can still be fixed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
amdgpu/pm: prevent array underflow in vega20_odn_edit_dpm_table()
In the PP_OD_EDIT_VDDC_CURVE case the "input_index" variable is capped at
2 but not checked for negative values so it results in an out of bounds
read. This value comes from the user via sysfs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/kexec: Fix double-free of elf header buffer
After
b3e34a47f989 ("x86/kexec: fix memory leak of elf header buffer"),
freeing image->elf_headers in the error path of crash_load_segments()
is not needed because kimage_file_post_load_cleanup() will take
care of that later. And not clearing it could result in a double-free.
Drop the superfluous vfree() call at the error path of
crash_load_segments().

Summary
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: rockchip: Fix refcount leak in rockchip_pinctrl_parse_groups
of_find_node_by_phandle() returns a node pointer with refcount incremented,
We should use of_node_put() on it when not needed anymore.
Add missing of_node_put() to avoid refcount leak.

In the Linux kernel, the following vulnerability has been resolved:
scsi: pm8001: Fix running_req for internal abort commands

The issue is that the per-device running_req read in
pm8001_dev_gone_notify() never goes to zero and we never make progress.
This is caused by missing accounting for running_req for when an internal
abort command completes.
In commit 2cbbf489778e ("scsi: pm8001: Use libsas internal abort support")
we started to send internal abort commands as a proper sas_task. In this
when we deliver a sas_task to HW the per-device running_req is incremented
in pm8001_queue_command(). However it is never decremented for internal
abort commnds, so decrement in pm8001_mpi_task_abort_resp().

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_fs: Fix epfile null pointer access after ep enable.
A race condition occurs when ffs_func_eps_enable() runs concurrently
with ffs_data_reset(). The ffs_data_clear() called in ffs_data_reset()
sets ffs->epfiles to NULL before resetting ffs->eps_count to 0, leading
to a NULL pointer dereference when accessing epfile->ep in
ffs_func_eps_enable() after successful usb_ep_enable().
The ffs->epfiles pointer is set to NULL in both ffs_data_clear() and
ffs_data_close() functions, and its modification is protected by the
spinlock ffs->eps_lock. And the whole ffs_func_eps_enable() function
is also protected by ffs->eps_lock.
Thus, add NULL pointer handling for ffs->epfiles in the
ffs_func_eps_enable() function to fix issues

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix rbtree traversal bug in ext4_mb_use_preallocated
During allocations, while looking for preallocations(PA) in the per
inode rbtree, we can't do a direct traversal of the tree because
ext4_mb_discard_group_preallocation() can paralelly mark the pa deleted
and that can cause direct traversal to skip some entries. This was
leading to a BUG_ON() being hit [1] when we missed a PA that could satisfy
our request and ultimately tried to create a new PA that would overlap
with the missed one.
To makes sure we handle that case while still keeping the performance of
the rbtree, we make use of the fact that the only pa that could possibly
overlap the original goal start is the one that satisfies the below
conditions:
1. It must have it's logical start immediately to the left of
(ie less than) original logical start.
2. It must not be deleted
To find this pa we use the following traversal method:
1. Descend into the rbtree normally to find the immediate neighboring
PA. Here we keep descending irrespective of if the PA is deleted or if
it overlaps with our request etc. The goal is to find an immediately
adjacent PA.
2. If the found PA is on right of original goal, use rb_prev() to find
the left adjacent PA.
3. Check if this PA is deleted and keep moving left with rb_prev() until
a non deleted PA is found.
4. This is the PA we are looking for. Now we can check if it can satisfy
the original request and proceed accordingly.
This approach also takes care of having deleted PAs in the tree.
(While we are at it, also fix a possible overflow bug in calculating the
end of a PA)

Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring: fix memory leak when removing provided buffers
When removing provided buffers, io_buffer structs are not being disposed
of, leading to a memory leak. They can't be freed individually, because
they are allocated in page-sized groups. They need to be added to some
free list instead, such as io_buffers_cache. All callers already hold
the lock protecting it, apart from when destroying buffers, so had to
extend the lock there.

The ucmd->log_sq_bb_count variable is controlled by the user so this
shift can wrap. Fix it by using check_shl_overflow() in the same way
that it was done in commit 515f60004ed9 ("RDMA/hns: Prevent undefined
behavior in hns_roce_set_user_sq_size()").

Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio_pmem: add the missing REQ_OP_WRITE for flush bio
When doing mkfs.xfs on a pmem device, the following warning was
------------[ cut here ]------------
WARNING: CPU: 2 PID: 384 at block/blk-core.c:751 submit_bio_noacct

The root cause is that submit_bio_noacct() needs bio_op() is either
WRITE or ZONE_APPEND for flush bio and async_pmem_flush() doesn't assign
REQ_OP_WRITE when allocating flush bio, so submit_bio_noacct just fail
the flush bio.
Simply fix it by adding the missing REQ_OP_WRITE for flush bio. And we
could fix the flush order issue and do flush optimization later.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: dvb-usb-v2: gl861: Fix null-ptr-deref in gl861_i2c_master_xfer
In gl861_i2c_master_xfer, msg is controlled by user. When msg[i].buf
is null and msg[i].len is zero, former checks on msg[i].buf would be
passed. Malicious data finally reach gl861_i2c_master_xfer. If accessing
msg[i].buf[0] without sanity check, null ptr deref would happen.
We add check on msg[i].len to prevent crash.

Summary
In the Linux kernel, the following vulnerability has been resolved:
comedi: pcl818: fix null-ptr-deref in pcl818_ai_cancel()
Syzbot identified an issue [1] in pcl818_ai_cancel(), which stems from
the fact that in case of early device detach via pcl818_detach(),
subdevice dev->read_subdev may not have initialized its pointer to
&struct comedi_async as intended. Thus, any such dereferencing of
&s->async->cmd will lead to general protection fault and kernel crash.
Mitigate this problem by removing a call to pcl818_ai_cancel() from
pcl818_detach() altogether. This way, if the subdevice setups its
support for async commands, everything async-related will be
handled via subdevice's own ->cancel() function in
comedi_device_detach_locked() even before pcl818_detach(). If no
support for asynchronous commands is provided, there is no need
to cancel anything either.
[1] Syzbot crash:

Summary
In the Linux kernel, the following vulnerability has been resolved:
team: Move team device type change at the end of team_port_add
Attempting to add a port device that is already up will expectedly fail,
but not before modifying the team device header_ops.
In the case of the syzbot reproducer the gre0 device is
already in state UP when it attempts to add it as a
port device of team0, this fails but before that
header_ops->create of team0 is changed from eth_header to ipgre_header
in the call to team_dev_type_check_change.
Later when we end up in ipgre_header() struct ip_tunnel* points to nonsense
as the private data of the device still holds a struct team.
Example sequence of iproute2 commands to reproduce the hang/BUG():
ip link add dev team0 type team
ip link add dev gre0 type gre
ip link set dev gre0 up
ip link set dev gre0 master team0
ip link set dev team0 up
ping -I team0 1.1.1.1
Move team_dev_type_check_change down where all other checks have passed
as it changes the dev type with no way to restore it in case
one of the checks that follow it fail.
Also make sure to preserve the origial mtu assignment:
- If port_dev is not the same type as dev, dev takes mtu from port_dev
- If port_dev is the same type as dev, port_dev takes mtu from dev
This is done by adding a conditional before the call to dev_set_mtu
to prevent it from assigning port_dev->mtu = dev->mtu and instead
letting team_dev_type_check_change assign dev->mtu = port_dev->mtu.
The conditional is needed because the patch moves the call to
team_dev_type_check_change past dev_set_mtu.
Testing:
- team device driver in-tree selftests
- Add/remove various devices as slaves of team device
- syzbot

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI/DOE: Fix destroy_work_on_stack() race
The following debug object splat was observed in testing:
ODEBUG: free active (active state 0) object: 0000000097d23782 object type: work_struct hint: doe_statemachine_work+0x0/0x510
WARNING: CPU: 1 PID: 71 at lib/debugobjects.c:514 debug_print_object+0x7d/0xb0
...
Workqueue: pci 0000:36:00.0 DOE [1 doe_statemachine_work
RIP: 0010:debug_print_object+0x7d/0xb0
...
Call Trace:
? debug_print_object+0x7d/0xb0
? __pfx_doe_statemachine_work+0x10/0x10
debug_object_free.part.0+0x11b/0x150
doe_statemachine_work+0x45e/0x510
process_one_work+0x1d4/0x3c0
This occurs because destroy_work_on_stack() was called after signaling
the completion in the calling thread. This creates a race between
destroy_work_on_stack() and the task->work struct going out of scope in
pci_doe().
Signal the work complete after destroying the work struct. This is safe
because signal_task_complete() is the final thing the work item does and
the workqueue code is careful not to access the work struct after.

Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix potential UAF in smb2_close_cached_fid()
find_or_create_cached_dir() could grab a new reference after kref_put()
had seen the refcount drop to zero but before cfid_list_lock is acquired
in smb2_close_cached_fid(), leading to use-after-free.
Switch to kref_put_lock() so cfid_release() is called with
cfid_list_lock held, closing that gap.

"value": "AV:N - The freeing side of the race is driven directly by a remote peer \u2014 `smb2_is_valid_lease_break()` (fs/smb/client/smb2misc.c:692) processes unsolicited SMB2 lease-break packets from the server and calls `cached_dir_lease_break()`, which clears the lease ref and queues the final `kref_put()`; server-forced reconnects similarly drive `invalidate_all_cached_dirs()`. A malicious, compromised, or MITM\u0027d SMB server therefore triggers the vulnerable refcount transition over the network.\nAC:L - The attacker controls the timing and rate of lease breaks/reconnects and can replay them indefinitely against routine directory activity on the mount, so the narrow window between `refcount_dec_and_test()` and the lock acquisition can be hit reliably by repetition. Race conditions the attacker can retry at will are Low complexity.\nPR:N - A malicious or MITM SMB server needs no credentials or privileges on the victim host; lease-break notifications are unsolicited server-to-client messages processed by the demultiplex thread. In the local variant the trigger is plain rmdir/stat/readdir on an accessible mount, requiring at most an unprivileged account.\nUI:R - Exploitation requires the victim to have the attacker-controlled SMB share mounted and to be performing directory lookups on it so that `find_or_create_cached_dir()` runs concurrently with the release path. The server cannot force that local access itself.\nS:U - The use-after-free is on a kernel slab object (`struct cached_fid`) and the impact stays within the kernel\u0027s own security authority \u2014 no VM, IOMMU, or sandbox boundary is crossed.\nC:H - A freed `cached_fid` holding `dentry`, `tcon`, `cifs_fid` handles, a mutex and list/work heads can be reallocated and sprayed with attacker-chosen data; the racing thread then reads it and returns cached directory/file_all_info state, giving a path to disclosing kernel memory. Per guidance, use-after-free is scored High for confidentiality.\nI:H - The stale object is written through as well as read (`kref_get`, `last_access_time`, list manipulation, `dput(cfid-\u003edentry)` on a reused pointer, and `SMB2_close()` on stale fid values), so heap grooming turns this into a write primitive over reallocated slab contents and potential control-flow hijack via the embedded `work_struct` function pointers.\nA:H - Losing the race produces a `refcount_t: addition on 0` warning followed by dereference and double-free of the `cached_fid` \u2014 including `dput()` on a freed dentry and slab corruption \u2014 reliably causing an oops or kernel panic."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dpu: Add check for cstate
As kzalloc may fail and return NULL pointer,
it should be better to check cstate
in order to avoid the NULL pointer dereference
in __drm_atomic_helper_crtc_reset.

Summary
In the Linux kernel, the following vulnerability has been resolved:
platform/x86: think-lmi: Fix memory leak when showing current settings
When retriving a item string with tlmi_setting(), the result has to be
freed using kfree(). In current_value_show() however, malformed
item strings are not freed, causing a memory leak.
Fix this by eliminating the early return responsible for this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix use-after-free bug of nilfs_root in nilfs_evict_inode()
During unmount process of nilfs2, nothing holds nilfs_root structure after
nilfs2 detaches its writer in nilfs_detach_log_writer(). However, since
nilfs_evict_inode() uses nilfs_root for some cleanup operations, it may
cause use-after-free read if inodes are left in "garbage_list" and
released by nilfs_dispose_list() at the end of nilfs_detach_log_writer().
Fix this issue by modifying nilfs_evict_inode() to only clear inode
without additional metadata changes that use nilfs_root if the file system
is degraded to read-only or the writer is detached.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/kexec: fix memory leak of elf header buffer
This is reported by kmemleak detector:
unreferenced object 0xffffc900002a9000 (size 4096):
comm "kexec", pid 14950, jiffies 4295110793 (age 373.951s)
hex dump (first 32 bytes):
7f 45 4c 46 02 01 01 00 00 00 00 00 00 00 00 00 .ELF............

[<0000000066e063a4>] entry_SYSCALL_64_after_hwframe+0x44/0xae
In crash_prepare_elf64_headers(), a buffer is allocated via vmalloc() to
store elf headers. While it's not freed back to system correctly when
kdump kernel is reloaded or unloaded. Then memory leak is caused. Fix it
by introducing x86 specific function arch_kimage_file_post_load_cleanup(),
and freeing the buffer there.
And also remove the incorrect elf header buffer freeing code. Before
calling arch specific kexec_file loading function, the image instance has
been initialized. So 'image->elf_headers' must be NULL. It doesn't make
sense to free the elf header buffer in the place.
Three different people have reported three bugs about the memory leak on
x86_64 inside Redhat.

Before\ncalling arch specific kexec_file loading function, the image instance has\nbeen initialized. So \u0027image-\u003eelf_headers\u0027 must be NULL. It doesn\u0027t make\nsense to free the elf header buffer in the place.\n\nThree different people have reported three bugs about the memory leak on\nx86_64 inside Redhat."

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: j1939: j1939_tp_tx_dat_new(): fix out-of-bounds memory access
In the j1939_tp_tx_dat_new() function, an out-of-bounds memory access
could occur during the memcpy() operation if the size of skb->cb is
larger than the size of struct j1939_sk_buff_cb. This is because the
memcpy() operation uses the size of skb->cb, leading to a read beyond
the struct j1939_sk_buff_cb.
Updated the memcpy() operation to use the size of struct
j1939_sk_buff_cb instead of the size of skb->cb. This ensures that the
memcpy() operation only reads the memory within the bounds of struct
j1939_sk_buff_cb, preventing out-of-bounds memory access.
Additionally, add a BUILD_BUG_ON() to check that the size of skb->cb
is greater than or equal to the size of struct j1939_sk_buff_cb. This
ensures that the skb->cb buffer is large enough to hold the
j1939_sk_buff_cb structure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gpu: host1x: Fix race in syncpt alloc/free
Fix race condition between host1x_syncpt_alloc()
and host1x_syncpt_put() by using kref_put_mutex()
instead of kref_put() + manual mutex locking.
This ensures no thread can acquire the
syncpt_mutex after the refcount drops to zero
but before syncpt_release acquires it.
This prevents races where syncpoints could
be allocated while still being cleaned up
from a previous release.
Remove explicit mutex locking in syncpt_release
as kref_put_mutex() handles this atomically.

Summary
In the Linux kernel, the following vulnerability has been resolved:
accel/qaic: Clean up integer overflow checking in map_user_pages()
The encode_dma() function has some validation on in_trans->size but it
would be more clear to move those checks to find_and_map_user_pages().
The encode_dma() had two checks:
if (in_trans->addr + in_trans->size < in_trans->addr || !in_trans->size)
return -EINVAL;
The in_trans->addr variable is the starting address. The in_trans->size
variable is the total size of the transfer. The transfer can occur in
parts and the resources->xferred_dma_size tracks how many bytes we have
already transferred.
This patch introduces a new variable "remaining" which represents the
amount we want to transfer (in_trans->size) minus the amount we have
already transferred (resources->xferred_dma_size).
I have modified the check for if in_trans->size is zero to instead check
if in_trans->size is less than resources->xferred_dma_size. If we have
already transferred more bytes than in_trans->size then there are negative
bytes remaining which doesn't make sense. If there are zero bytes
remaining to be copied, just return success.
The check in encode_dma() checked that "addr + size" could not overflow
and barring a driver bug that should work, but it's easier to check if
we do this in parts. First check that "in_trans->addr +
resources->xferred_dma_size" is safe. Then check that "xfer_start_addr +
remaining" is safe.
My final concern was that we are dealing with u64 values but on 32bit
systems the kmalloc() function will truncate the sizes to 32 bits. So
I calculated "total = in_trans->size + offset_in_page(xfer_start_addr);"
and returned -EINVAL if it were >= SIZE_MAX. This will not affect 64bit
systems.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Prevent access to vCPU events before init
Another day, another syzkaller bug. KVM erroneously allows userspace to
pend vCPU events for a vCPU that hasn't been initialized yet, leading to
KVM interpreting a bunch of uninitialized garbage for routing /
injecting the exception.
In one case the injection code and the hyp disagree on whether the vCPU
has a 32bit EL1 and put the vCPU into an illegal mode for AArch64,
tripping the BUG() in exception_target_el() during the next injection:

Summary
In the Linux kernel, the following vulnerability has been resolved:
phy: tegra: xusb: Clear the driver reference in usb-phy dev
For the dual-role port, it will assign the phy dev to usb-phy dev and
use the port dev driver as the dev driver of usb-phy.
When we try to destroy the port dev, it will destroy its dev driver
as well. But we did not remove the reference from usb-phy dev. This
might cause the use-after-free issue in KASAN.

No physical device insertion is needed since the padctl is an on-SoC platform device.\nAC:L - The dangling `dev.driver` and its subsequent dereference occur deterministically in the same teardown sequence \u2014 `devres_release_all()` frees the fake `device_driver` in `device_del(\u0026port-\u003edev)` and `phy_destroy()` reads it moments later \u2014 with no race the attacker cannot influence. The freed object is a small kmalloc allocation that a local attacker can reliably groom.\nPR:L - Exploitation of the freed `struct device_driver` \u2014 spraying the slab so the driver core reads attacker-controlled `pm`/`name` fields \u2014 is performed by an ordinary unprivileged local process, and the same teardown also executes on the boot-time probe-failure path with no privilege at all. Consistent with prior scoring of driver-remove-path use-after-frees in this subsystem class, PR:L is the higher defensible value.\nUI:N - No victim action is required; the use-after-free occurs automatically within the driver removal/probe-failure sequence. The attacker only needs to have its heap spray in place.\nS:U - Both the freed object and the code dereferencing it live in the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary. This is a standard in-kernel memory-safety defect.\nC:H - The stale pointer is read by `dev_driver_string()` (`drv-\u003ename` passed to printk) and by `device_pm_check_callbacks()`, so reallocated heap contents can be dereferenced and leaked into kernel logs. Per use-after-free guidance, control over the freed object\u0027s contents yields an arbitrary-read primitive.\nI:H - `__rpm_get_callback()` loads a function pointer out of `dev-\u003edriver-\u003epm` on the freed object and invokes it, giving a direct control-flow hijack primitive once the slab object is reallocated with attacker-controlled data. Use-after-free of a structure containing function pointers is treated as High integrity impact.\nA:H - The KASAN-reported use-after-free dereferences freed memory during device removal, producing an oops or panic even without deliberate exploitation. Any kernel crash is scored High."

- CWE-190 - Integer Overflow or Wraparound
Summary
An integer overflow flaw was found in the Linux kernel. This issue leads to the kernel allocating `skb_shared_info` in the userspace, which is exploitable in systems without SMAP protection since `skb_shared_info` contains references to function pointers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: stm32: Fix refcount leak in stm32_pctrl_get_irq_domain
of_irq_find_parent() returns a node pointer with refcount incremented,
We should use of_node_put() on it when not needed anymore.
Add missing of_node_put() to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/irdma: Cap MSIX used to online CPUs + 1
The irdma driver can use a maximum number of msix vectors equal
to num_online_cpus() + 1 and the kernel warning stack below is shown
if that number is exceeded.
The kernel throws a warning as the driver tries to update the affinity
hint with a CPU mask greater than the max CPU IDs. Fix this by capping
the MSIX vectors to num_online_cpus() + 1.
WARNING: CPU: 7 PID: 23655 at include/linux/cpumask.h:106 irdma_cfg_ceq_vector+0x34c/0x3f0 [irdma]

Summary
In the Linux kernel, the following vulnerability has been resolved:
remoteproc: sysmon: fix memory leak in qcom_add_sysmon_subdev()
The kfree() should be called when of_irq_get_byname() fails or
devm_request_threaded_irq() fails in qcom_add_sysmon_subdev(),
otherwise there will be a memory leak, so add kfree() to fix it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: Fix use-after-free in ath9k_hif_usb_disconnect()
This patch fixes a use-after-free in ath9k that occurs in
ath9k_hif_usb_disconnect() when ath9k_destroy_wmi() is trying to access
'drv_priv' that has already been freed by ieee80211_free_hw(), called by
ath9k_htc_hw_deinit(). The patch moves ath9k_destroy_wmi() before
ieee80211_free_hw(). Note that urbs from the driver should be killed
before freeing 'wmi' with ath9k_destroy_wmi() as their callbacks will
access 'wmi'.
Found by a modified version of syzkaller.

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: fix mempool alloc size
Convert the max size to bytes to match the units of the divisor that
calculates the worst-case number of PRP entries.
The result is used to determine how many PRP Lists are required. The
code was previously rounding this to 1 list, but we can require 2 in the
worst case. In that scenario, the driver would corrupt memory beyond the
size provided by the mempool.
While unlikely to occur (you'd need a 4MB in exactly 127 phys segments
on a queue that doesn't support SGLs), this memory corruption has been
observed by kfence.

This happens because iocg->ioc is NULL. The field is initialized by
ioc_pd_init() and never cleared. The NULL deref is caused by
blkcg_activate_policy() installing blkg_policy_data before initializing it.
blkcg_activate_policy() was doing the following:
1. Allocate pd's for all existing blkg's and install them in blkg->pd[].
2. Initialize all pd's.
3. Online all pd's.
blkcg_activate_policy() only grabs the queue_lock and may release and
re-acquire the lock as allocation may need to sleep. ioc_weight_write()
grabs blkcg->lock and iterates all its blkg's. The two can race and if
ioc_weight_write() runs during #1 or between #1 and #2, it can encounter a
pd which is not initialized yet, leading to crash.
The crash can be reproduced with the following script:

I don't see a reason why all pd's should be allocated, initialized and
onlined together. The only ordering requirement is that parent blkgs to be
initialized and onlined before children, which is guaranteed from the
walking order. Let's fix the bug by allocating, initializing and onlining pd
for each blkg and holding blkcg->lock over initialization and onlining. This
ensures that an installed blkg is always fully initialized and onlined
removing the the race window.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath10k: Delay the unmapping of the buffer
On WCN3990, we are seeing a rare scenario where copy engine hardware is
sending a copy complete interrupt to the host driver while still
processing the buffer that the driver has sent, this is leading into an
SMMU fault triggering kernel panic. This is happening on copy engine
channel 3 (CE3) where the driver normally enqueues WMI commands to the
firmware. Upon receiving a copy complete interrupt, host driver will
immediately unmap and frees the buffer presuming that hardware has
processed the buffer. In the issue case, upon receiving copy complete
interrupt, host driver will unmap and free the buffer but since hardware
is still accessing the buffer (which in this case got unmapped in
parallel), SMMU hardware will trigger an SMMU fault resulting in a
kernel panic.
In order to avoid this, as a work around, add a delay before unmapping
the copy engine source DMA buffer. This is conditionally done for
WCN3990 and only for the CE3 channel where issue is seen.
Below is the crash signature:

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath10k: Delay the unmapping of the buffer\n\nOn WCN3990, we are seeing a rare scenario where copy engine hardware is\nsending a copy complete interrupt to the host driver while still\nprocessing the buffer that the driver has sent, this is leading into an\nSMMU fault triggering kernel panic. This is happening on copy engine\nchannel 3 (CE3) where the driver normally enqueues WMI commands to the\nfirmware. Upon receiving a copy complete interrupt, host driver will\nimmediately unmap and frees the buffer presuming that hardware has\nprocessed the buffer. In the issue case, upon receiving copy complete\ninterrupt, host driver will unmap and free the buffer but since hardware\nis still accessing the buffer (which in this case got unmapped in\nparallel), SMMU hardware will trigger an SMMU fault resulting in a\nkernel panic.\n\nIn order to avoid this, as a work around, add a delay before unmapping\nthe copy engine source DMA buffer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
remoteproc: qcom: q6v5: Fix potential null-ptr-deref in q6v5_wcss_init_mmio()
q6v5_wcss_init_mmio() will call platform_get_resource_byname() that may
fail and return NULL. devm_ioremap() will use res->start as input, which
may causes null-ptr-deref. Check the ret value of
platform_get_resource_byname() to avoid the null-ptr-deref.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: do not allow gso_size to be set to GSO_BY_FRAGS
One missing check in virtio_net_hdr_to_skb() allowed
syzbot to crash kernels again [1]
Do not allow gso_size to be set to GSO_BY_FRAGS (0xffff),
because this magic value is used by the kernel.

Above issue may happen as follows:
-------------------------------------
ext4_fill_super
ext4_orphan_cleanup
ext4_enable_quotas
ext4_quota_enable
ext4_iget --> get error inode <5>
ext4_ext_check_inode --> Wrong imode makes it escape inspection
make_bad_inode(inode) --> EXT4_BOOT_LOADER_INO set imode
dquot_load_quota_inode
vfs_setup_quota_inode --> check pass
dquot_load_quota_sb
v2_check_quota_file
v2_read_header
ext4_quota_read
ext4_bread
ext4_getblk
ext4_map_blocks
ext4_ext_map_blocks
ext4_find_extent
ext4_cache_extents
ext4_es_cache_extent
__es_tree_search.isra.0
ext4_es_end --> Wrong extents trigger BUG_ON
In the above issue, s_usr_quota_inum is set to 5, but inode<5> contains
incorrect imode and disordered extents. Because 5 is EXT4_BOOT_LOADER_INO,
the ext4_ext_check_inode check in the ext4_iget function can be bypassed,
finally, the extents that are not checked trigger the BUG_ON in the
__es_tree_search function. To solve this issue, check whether the inode is
bad_inode in vfs_setup_quota_inode().

Summary
In the Linux kernel, the following vulnerability has been resolved:
tty: fix out-of-bounds access in tty_driver_lookup_tty()
When specifying an invalid console= device like console=tty3270,
tty_driver_lookup_tty() returns the tty struct without checking
whether index is a valid number.
To reproduce:
qemu-system-x86_64 -enable-kvm -nographic -serial mon:stdio \
-kernel ../linux-build-x86/arch/x86/boot/bzImage \
-append "console=ttyS0 console=tty3270"
This crashes with:

Summary
In the Linux kernel, the following vulnerability has been resolved:
driver: soc: xilinx: use _safe loop iterator to avoid a use after free
The hash_for_each_possible() loop dereferences "eve_data" to get the
next item on the list. However the loop frees eve_data so it leads to
a use after free. Use hash_for_each_possible_safe() instead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: dvm: Fix memcpy: detected field-spanning write backtrace
A received TKIP key may be up to 32 bytes because it may contain
MIC rx/tx keys too. These are not used by iwl and copying these
over overflows the iwl_keyinfo.key field.
Add a check to not copy more data to iwl_keyinfo.key then will fit.
This fixes backtraces like this one:
memcpy: detected field-spanning write (size 32) of single field "sta_cmd.key.key" at drivers/net/wireless/intel/iwlwifi/dvm/sta.c:1103 (size 16)

"value": "AV:A - The vulnerable path is the 802.11 key-installation path of the iwlwifi dvm WiFi driver, reached when a TKIP key is programmed after association/4-way handshake with a wireless peer on the same WiFi segment. iwldvm supports AP, IBSS/RSN and STATION modes, so an adjacent wireless peer (rogue AP or associating station) drives whether the 32-byte TKIP cipher path is taken, making this Adjacent rather than Local.\nAC:L - The overflow is fully deterministic \u2014 mac80211 always passes keylen 32 for WLAN_CIPHER_SUITE_TKIP into a 16-byte field, so every TKIP key install triggers it with no race, timing window, or memory-layout dependency. TKIP is a standard supported cipher and CONFIG_FORTIFY_SOURCE is enabled by default in mainstream distro and Android kernels.\nPR:N - In AP/IBSS mode the key install is performed automatically by hostapd on behalf of an associating adjacent station, and in STA mode by wpa_supplicant when a TKIP-advertising AP is joined; in neither case does the attacker hold any privilege or account on the vulnerable host. Being a WLAN participant is not a privilege level on the target system.\nUI:N - When the affected host runs an AP or IBSS/RSN network with TKIP, an adjacent peer\u0027s association alone causes the per-station TKIP key to be programmed and the overflow to execute, with no action by any local user. No file must be opened, filesystem mounted, or connection manually initiated.\nS:U - The over-write stays within the on-stack struct iwl_addsta_cmd owned by the driver and the resulting fault or firmware command corruption is confined to the kernel\u0027s own security authority. There is no crossing of a VM, IOMMU, or sandbox boundary.\nC:L - There is no out-of-bounds read and no arbitrary memory disclosure, but the FORTIFY WARN backtrace exposes kernel text addresses, register state, and stack contents to the kernel log, and secret TKIP MIC key material is written into the tx_secur_seq_cnt field handed to device firmware, with a plausible TKIP TSC/IV-reuse path against link traffic. This is a limited, bounded exposure rather than arbitrary read.\nI:L - The write is a bounded 16-byte field-spanning overflow that provably cannot escape the 92-byte enclosing struct (fortify\u0027s p_size check confirms no struct-level overflow), so no return address, stack canary, or adjacent heap object can be corrupted and the content is not attacker-controlled. It does, however, corrupt the tx_secur_seq_cnt and hw_tkip_mic_rx_key fields programmed into the device, altering the link\u0027s TKIP sequence-counter state \u2014 a limited modification.\nA:H - The field-spanning write triggers a FORTIFY_SOURCE WARNING with full backtrace, which is an immediate kernel panic on the many hardened, Android, cloud, and CI kernels that set panic_on_warn=1. Additionally, the bogus TKIP TX sequence counter pushed to firmware can break the wireless link through peer replay-detection drops."

(The local /dev/vhci and N_HCI ldisc variants require root/CAP_NET_ADMIN in the init namespace, so the unauthenticated transport path is the more severe one.)\nUI:N - Frames are consumed automatically by the hci_rx_work workqueue as soon as the Bluetooth adapter is up; no victim action of any kind is needed.\nS:U - The invalid read and the resulting state corruption are entirely within the kernel\u0027s own security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:L - Up to two bytes of uninitialized/out-of-bounds heap memory past skb-\u003edata are read into the handle field and disclosed to the kernel log via bt_dev_err(\"ACL packet for unknown connection handle %d\"). The disclosure is real but strictly bounded to a couple of bytes, not an arbitrary read.\nI:L - Because skb_pull() fails silently, the uninitialized handle selects an arbitrary existing hci_conn and the uninitialized flags inject the unstripped header bytes into that unrelated connection\u0027s L2CAP reassembly buffer, discarding or corrupting its pending frame. This is bounded state modification, not an arbitrary write.\nA:H - The bogus ACL_START/ACL_CONT fragments drive l2cap_recv_reset() and l2cap_conn_unreliable(ECOMM) on a victim connection, tearing down an unrelated Bluetooth link, and the attack is repeatable without limit; on KASAN/KMSAN-instrumented or panic-on-warn hardened builds the invalid access is itself fatal."

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: bitblit: bound-check glyph index in bit_putcs*
bit_putcs_aligned()/unaligned() derived the glyph pointer from the
character value masked by 0xff/0x1ff, which may exceed the actual font's
glyph count and read past the end of the built-in font array.
Clamp the index to the actual glyph count before computing the address.
This fixes a global out-of-bounds read reported by syzbot.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfs4_setup_readdir(): insufficient locking for ->d_parent->d_inode dereferencing
Theoretically it's an oopsable race, but I don't believe one can manage
to hit it on real hardware; might become doable on a KVM, but it still
won't be easy to attack.
Anyway, it's easy to deal with - since xdr_encode_hyper() is just a call of
put_unaligned_be64(), we can put that under ->d_lock and be done with that.

Summary
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Fix data races around sk->sk_shutdown.
KCSAN found a data race around sk->sk_shutdown where unix_release_sock()
and unix_shutdown() update it under unix_state_lock(), OTOH unix_poll()
and unix_dgram_poll() read it locklessly.
We need to annotate the writes and reads with WRITE_ONCE() and READ_ONCE().

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvmet-fc: avoid scheduling association deletion twice
When forcefully shutting down a port via the configfs interface,
nvmet_port_subsys_drop_link() first calls nvmet_port_del_ctrls() and
then nvmet_disable_port(). Both functions will eventually schedule all
remaining associations for deletion.
The current implementation checks whether an association is about to be
removed, but only after the work item has already been scheduled. As a
result, it is possible for the first scheduled work item to free all
resources, and then for the same work item to be scheduled again for
deletion.
Because the association list is an RCU list, it is not possible to take
a lock and remove the list entry directly, so it cannot be looked up
again. Instead, a flag (terminating) must be used to determine whether
the association is already in the process of being deleted.

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: xsk: Fix invalid buffer access for legacy rq
The below crash can be encountered when using xdpsock in rx mode for
legacy rq: the buffer gets released in the XDP_REDIRECT path, and then
once again in the driver. This fix sets the flag to avoid releasing on
the driver side.
XSK handling of buffers for legacy rq was relying on the caller to set
the skip release flag. But the referenced fix started using fragment
counts for pages instead of the skip flag.
Crash log:

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: ocb: don't leave if not joined
If there's no OCB state, don't ask the driver/mac80211 to
leave, since that's just confusing. Since set/clear the
chandef state, that's a simple check.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: mtu3: fix kernel panic at qmu transfer done irq handler
When handle qmu transfer irq, it will unlock @mtu->lock before give back
request, if another thread handle disconnect event at the same time, and
try to disable ep, it may lock @mtu->lock and free qmu ring, then qmu
irq hanlder may get a NULL gpd, avoid the KE by checking gpd's value before
handling it.
e.g.
qmu done irq on cpu0 thread running on cpu1
qmu_done_tx()
handle gpd [0]
mtu3_requ_complete() mtu3_gadget_ep_disable()
unlock @mtu->lock
give back request lock @mtu->lock
mtu3_ep_disable()
mtu3_gpd_ring_free()
unlock @mtu->lock
lock @mtu->lock
get next gpd [1]
[1]: goto [0] to handle next gpd, and next gpd may be NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Clean up only new IRQ glue on request_irq() failure
The mlx5_irq_alloc() function can inadvertently free the entire rmap
and end up in a crash[1] when the other threads tries to access this,
when request_irq() fails due to exhausted IRQ vectors. This commit
modifies the cleanup to remove only the specific IRQ mapping that was
just added.
This prevents removal of other valid mappings and ensures precise
cleanup of the failed IRQ allocation's associated glue object.
Note: This error is observed when both fwctl and rds configs are enabled.

The dangling `netdev-\u003erx_cpu_rmap` is later consumed in the RX softirq, but the attacker\u0027s trigger for the free is purely local.\nAC:L - The attacker drives the triggering condition themselves by repeatedly allocating completion vectors (CQ per comp_vector across mlx5 uverbs devices, or channel/link-up cycles) until MSI-X/x86 vector space is exhausted and `request_irq()` returns -ENOSPC; the very next allocation attempt deterministically executes the buggy cleanup. `CONFIG_RFS_ACCEL` is `default y`, so no rare config is needed, and the dangling `eq_table-\u003ermap`/`rx_cpu_rmap` pointers persist afterwards with no race to win.\nPR:L - `mlx5_comp_eqn_get()` is reachable from `ib_uverbs_create_cq` with a user-chosen `comp_vector` and requires no capability beyond an open handle on `/dev/infiniband/uverbs*`, which rdma-core udev rules commonly expose mode 0666 on exactly the RDMA/HPC hosts that carry mlx5 hardware. An unprivileged local user can therefore force the dynamic IRQ allocations and the `request_irq()` failure.\nUI:N - No victim action is required; the attacker\u0027s own syscalls allocate the completion queues and trigger the failing IRQ request, and the resulting stale pointer is consumed by kernel teardown and RX steering without any user involvement.\nS:U - The premature free and all subsequent corruption occur within the kernel\u0027s own slab and driver state; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free of the `struct cpu_rmap` \u2014 `free_irq_cpu_rmap()` and `cpu_rmap_lookup_obj()` read `rmap-\u003eobj[]`/`rmap-\u003enear[]` out of a freed, sprayable kmalloc object, and `set_rps_cpu()` uses the freed `rx_cpu_rmap` index to address `dev-\u003e_rx` out of bounds, giving an attacker who reclaims the slot a kernel-memory read primitive.\nI:H - After the free, `irq_cpu_rmap_add()` performs `kref_get()` and `rmap-\u003eobj[index] = glue` into the reallocated object, and `free_irq_cpu_rmap()` runs `irq_set_affinity_notifier()`/`kref_put()` on a fully attacker-controlled `glue` pointer read from freed memory \u2014 refcount manipulation, controlled pointer write, and a double-free path suitable for control-flow hijack.\nA:H - The reported failure is a general protection fault in `free_irq_cpu_rmap+0x23` ending in \"Kernel panic - not syncing: Fatal exception\", and any thread touching the stale `eq_table-\u003ermap` or `netdev-\u003erx_cpu_rmap` can crash the machine."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: qlogic/qede: fix potential out-of-bounds read in qede_tpa_cont() and qede_tpa_end()
The loops in 'qede_tpa_cont()' and 'qede_tpa_end()', iterate
over 'cqe->len_list[]' using only a zero-length terminator as
the stopping condition. If the terminator was missing or
malformed, the loop could run past the end of the fixed-size array.
Add an explicit bound check using ARRAY_SIZE() in both loops to prevent
a potential out-of-bounds access.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iomap: Fix possible overflow condition in iomap_write_delalloc_scan
folio_next_index() returns an unsigned long value which left shifted
by PAGE_SHIFT could possibly cause an overflow on 32-bit system. Instead
use folio_pos(folio) + folio_size(folio), which does this correctly.

No network-facing service reliably produces the required short-write-with-partial-copy condition, so local access is needed.\nAC:L - The attacker deterministically controls every trigger condition: creating a file larger than 4 GiB, dirtying folios above that offset, and forcing a short write by passing a buffer that straddles an unmapped/PROT_NONE page so `fault_in_iov_iter_readable()` fails. On the affected deployment class (32-bit ARM/x86 embedded, industrial and NAS devices running XFS) the 32-bit truncation is a fixed property of the target, not a race or a condition outside attacker control.\nPR:L - Only an unprivileged local account with write access to any file on an XFS filesystem (e.g. /tmp, /var, or a home directory) is required. No capability, root, or namespace trickery is needed anywhere along the `vfs_write` \u2192 iomap path.\nUI:N - The attacker performs the entire sequence \u2014 extending the file past 4 GiB, dirtying page cache, issuing the faulting write \u2014 in its own process. No victim action or cooperation is required.\nS:U - The overflow and its effects are confined to the kernel\u0027s own filesystem/page-cache state on the same system; no VM, IOMMU, or sandbox security boundary is crossed.\nC:N - The miscalculation only causes delalloc (unwritten reservation) extents to be removed; `xfs_bmap_punch_delalloc_range()` explicitly skips real allocated extents via the `isnullstartblock()` check, so no out-of-bounds read occurs and punched ranges read back as zeroes rather than exposing stale disk or kernel memory.\nI:H - The wrapped `punch_start_byte` causes delalloc reservations to be punched over a range up to ~4 GiB below the intended one, leaving dirty page-cache data with no backing reservation; `xfs_map_blocks()` then finds a hole at writeback and the data is silently discarded, permanently destroying file contents \u2014 including data written concurrently by other users to a shared file \u2014 and leaving the on-disk extent state inconsistent with the page cache.\nA:H - The corrupted punch range trips `WARN_ON_ONCE(start_byte \u003c punch_start_byte)` (a panic under `panic_on_warn`) and drives writeback into holes, producing XFS writeback errors and filesystem shutdown that renders the volume unusable; on affected kernels the same 32-bit truncation in the adjacent loop-advance expression additionally yields an unkillable infinite loop while holding `i_rwsem` and the mapping invalidate lock, permanently wedging the inode and burning a CPU."

SELinux: Context system_u:object_r:pssp_rsyslog_log_t:s0:c0 is
not valid (left unmapped).
It was found that within a critical section of spin_lock_irqsave in
sidtab_context_to_sid(), convert_context() (hooked by
sidtab_convert_params.func) might cause the process to sleep via
allocating memory with GFP_KERNEL, which is problematic.
As Ondrej pointed out [1], convert_context()/sidtab_convert_params.func
has another caller sidtab_convert_tree(), which is okay with GFP_KERNEL.
Therefore, fix this problem by adding a gfp_t argument for
convert_context()/sidtab_convert_params.func and pass GFP_KERNEL/_ATOMIC
properly in individual callers.

[ 15.266376] </TASK>
When calling hfsplus_bmap_alloc to allocate a free node, this function
first retrieves the bitmap from header node and map node using node->page
together with the offset and length from hfs_brec_lenoff
```
len = hfs_brec_lenoff(node, 2, &off16);
off = off16;
off += node->page_offset;
pagep = node->page + (off >> PAGE_SHIFT);
data = kmap_local_page(*pagep);
```
However, if the retrieved offset or length is invalid(i.e. exceeds
node_size), the code may end up accessing pages outside the allocated
range for this node.
This patch adds proper validation of both offset and length before use,
preventing out-of-bounds page access. Move is_bnode_offset_valid and
check_and_correct_requested_length to hfsplus_fs.h, as they may be
required by other functions.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: Fix the error length of VALIDATE_NEGOTIATE_INFO message
Commit d5c7076b772a ("smb3: add smb3.1.1 to default dialect list")
extend the dialects from 3 to 4, but forget to decrease the extended
length when specific the dialect, then the message length is larger
than expected.
This maybe leak some info through network because not initialize the
message body.
After apply this patch, the VALIDATE_NEGOTIATE_INFO message length is
reduced from 28 bytes to 26 bytes.

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7921e: fix rmmod crash in driver reload test
In insmod/rmmod stress test, the following crash dump shows up immediately.
The problem is caused by missing mt76_dev in mt7921_pci_remove(). We
should make sure the drvdata is ready before probe() finished.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915: Fix NULL ptr deref by checking new_crtc_state
intel_atomic_get_new_crtc_state can return NULL, unless crtc state wasn't
obtained previously with intel_atomic_get_crtc_state, so we must check it
for NULLness here, just as in many other places, where we can't guarantee
that intel_atomic_get_crtc_state was called.
We are currently getting NULL ptr deref because of that, so this fix was
confirmed to help.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: EC: Fix oops when removing custom query handlers
When removing custom query handlers, the handler might still
be used inside the EC query workqueue, causing a kernel oops
if the module holding the callback function was already unloaded.
Fix this by flushing the EC query workqueue when removing
custom query handlers.
Tested on a Acer Travelmate 4002WLMi

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: Disable AFBC support on Mediatek DRM driver
Commit c410fa9b07c3 ("drm/mediatek: Add AFBC support to Mediatek DRM
driver") added AFBC support to Mediatek DRM and enabled the
32x8/split/sparse modifier.
However, this is currently broken on Mediatek MT8188 (Genio 700 EVK
platform); tested using upstream Kernel and Mesa (v25.2.1), AFBC is used by
default since Mesa v25.0.
Kernel trace reports vblank timeouts constantly, and the render is garbled:
```

Until this gets fixed upstream, disable AFBC support on this platform, as
it's currently broken with upstream Mesa.

No race, no unpredictable memory layout, and no condition outside the attacker\u0027s control is involved.\nPR:L - An unprivileged local user in the graphical session (or any user able to open the card node and become DRM master when none is held) can perform the ADDFB2 + atomic commit; no root or CAP_SYS_ADMIN is needed. In practice Mesa \u003e= 25.0 selects AFBC by default, so an ordinary unprivileged GL/compositor client reaches the broken path with no special effort.\nUI:N - The attacker issues the framebuffer-creation and atomic-commit ioctls directly from their own process.

Compounding this, the timed-out vblank wait lets drm_atomic_helper_cleanup_planes() release the buffer while the engine is still scanning it, so freed and reallocated kernel memory is decoded and rendered to the display.\nI:N - The AFBC path only programs the overlay engine to read from the framebuffer; there is no out-of-bounds or use-after-free write, and no kernel data structure is modified by the attacker. The observed garbled output is a consequence of the faulty reads, not of any memory corruption.\nA:H - Every AFBC commit stalls the events_unbound commit worker for the full 1000 ms wait_event_timeout in drm_atomic_helper_wait_for_vblanks() and triggers a WARN(), which is an immediate kernel panic on panic_on_warn systems and a repeating splat flood otherwise. The display pipeline is left effectively hung with garbled output, and the buffer is freed out from under the still-active DMA engine."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Free special fields when update [lru_,]percpu_hash maps
As [lru_,]percpu_hash maps support BPF_KPTR_{REF,PERCPU}, missing
calls to 'bpf_obj_free_fields()' in 'pcpu_copy_value()' could cause the
memory referenced by BPF_KPTR_{REF,PERCPU} fields to be held until the
map gets freed.
Fix this by calling 'bpf_obj_free_fields()' after
'copy_map_value[,_long]()' in 'pcpu_copy_value()'.

Summary
In the Linux kernel, the following vulnerability has been resolved:
pmdomain: arm: scmi: Fix genpd leak on provider registration failure
If of_genpd_add_provider_onecell() fails during probe, the previously
created generic power domains are not removed, leading to a memory leak
and potential kernel crash later in genpd_debug_add().
Add proper error handling to unwind the initialized domains before
returning from probe to ensure all resources are correctly released on
failure.
Example crash trace observed without this fix:

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: target: iscsi: Fix buffer overflow in lio_target_nacl_info_show()
The function lio_target_nacl_info_show() uses sprintf() in a loop to print
details for every iSCSI connection in a session without checking for the
buffer length. With enough iSCSI connections it's possible to overflow the
buffer provided by configfs and corrupt the memory.
This patch replaces sprintf() with sysfs_emit_at() that checks for buffer
boundries.

This is the stored-payload pattern: the payload is planted remotely at the iSCSI protocol level and rendered later.\nAC:L - On an MC/S-enabled target (the deployment this was reported against) the attacker deterministically opens the ~25+ connections needed to exceed the 4096-byte page; no race, no memory-layout guess, no unpredictable condition is involved. Each additional login reliably extends the overflow.\nPR:N - iSCSI targets are very commonly run with CHAP disabled (`authentication=0`, or demo mode), and the initiator IQN matching an ACL is merely a string the peer asserts in the login PDU, so an unauthenticated remote peer can establish the multi-connection session. Even the connection-count growth occurs during login processing before any real credential check in that configuration.\nUI:R - The overflow executes when the world-readable configfs attribute `acls/\u003ciqn\u003e/info` is read \u2014 by an administrator, targetcli/rtslib, or a monitoring agent \u2014 which the remote attacker cannot initiate. That read is routine on managed storage nodes but is still a separate party\u0027s action.\nS:U - The corruption is kernel memory overwritten by kernel code within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Unbounded page-overflow with attacker-influenced content into adjacent buddy-allocator pages is a memory-corruption primitive that can be steered into slab objects, pointers, or page metadata and leveraged for arbitrary kernel memory disclosure.\nI:H - This is an out-of-bounds write of attacker-controlled length (scaling with connection count, up to megabytes) with partly attacker-chosen bytes (CIDs, peer addresses, StatSN) past the end of a kernel page, giving a strong write primitive suitable for control-flow hijack.\nA:H - Overwriting arbitrary adjacent kernel pages while holding `conn_lock` and `nacl_sess_lock` reliably corrupts unrelated kernel state and causes oops/panic; the attacker can repeat it on every read."

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/hugetlb: fix folio is still mapped when deleted
Migration may be raced with fallocating hole. remove_inode_single_folio
will unmap the folio if the folio is still mapped. However, it's called
without folio lock. If the folio is migrated and the mapped pte has been
converted to migration entry, folio_mapped() returns false, and won't
unmap it. Due to extra refcount held by remove_inode_single_folio,
migration fails, restores migration entry to normal pte, and the folio is
mapped again. As a result, we triggered BUG in filemap_unaccount_folio.
The log is as follows:
BUG: Bad page cache in process hugetlb pfn:156c00

There is no network-reachable path into hugetlbfs fallocate.\nAC:L - The attacker controls both sides of the race with its own threads \u2014 one looping on punch-hole, the other looping on NUMA migration of the same mapping \u2014 and can retry indefinitely at no cost until the window is hit. Per race-condition guidance, attacker-driven races are Low.\nPR:L - `memfd_create(MFD_HUGETLB)` uses HUGETLB_ANONHUGE_INODE and bypasses the `can_do_hugetlb_shm()`/CAP_IPC_LOCK check entirely, and `MPOL_MF_MOVE` on one\u0027s own address space needs no capability, so an ordinary unprivileged local user can reach the whole path.\nUI:N - The attacking process performs every step itself; no victim action, mount, or file open by another user is needed.\nS:U - The vulnerable code and the corrupted resources are both in the host kernel\u0027s memory management, so the impact stays within a single security authority despite the severity.\nC:H - The huge page is unlinked from the page cache with its `mapping` cleared while the attacker retains writable PTEs, and hugetlb folios are explicitly excluded from `filemap_unaccount_folio()`\u0027s recovery heuristic \u2014 leaving a stale mapping to a 2MB page the kernel may recycle to another process, container, or hugepage-backed KVM guest, yielding arbitrary read of that memory.\nI:H - The same stale writable mapping gives an arbitrary-write primitive over whatever the kernel later places in that recycled huge page, and the hugetlb reserve/subpool counters are decremented for a page still in use, corrupting pool accounting \u2014 memory corruption of this class is leveragable for control-flow hijack.\nA:H - The bug\u0027s directly observed symptom is the `BUG: Bad page cache ... still mapped when deleted` report, which is a hard `VM_BUG_ON_FOLIO()` panic under CONFIG_DEBUG_VM and a `TAINT_BAD_PAGE` plus unrecoverable page-cache/hugetlb-pool corruption otherwise, repeatable at will by an unprivileged user."

Summary
In the Linux kernel, the following vulnerability has been resolved:
HSI: omap_ssi: Fix refcount leak in ssi_probe
When returning or breaking early from a
for_each_available_child_of_node() loop, we need to explicitly call
of_node_put() on the child node to possibly release the node.

Summary
In the Linux kernel, the following vulnerability has been resolved:
arch_topology: Fix incorrect error check in topology_parse_cpu_capacity()
Fix incorrect use of PTR_ERR_OR_ZERO() in topology_parse_cpu_capacity()
which causes the code to proceed with NULL clock pointers. The current
logic uses !PTR_ERR_OR_ZERO(cpu_clk) which evaluates to true for both
valid pointers and NULL, leading to potential NULL pointer dereference
in clk_get_rate().
Per include/linux/err.h documentation, PTR_ERR_OR_ZERO(ptr) returns:
"The error code within @ptr if it is an error pointer; 0 otherwise."
This means PTR_ERR_OR_ZERO() returns 0 for both valid pointers AND NULL
pointers. Therefore !PTR_ERR_OR_ZERO(cpu_clk) evaluates to true (proceed)
when cpu_clk is either valid or NULL, causing clk_get_rate(NULL) to be
called when of_clk_get() returns NULL.
Replace with !IS_ERR_OR_NULL(cpu_clk) which only proceeds for valid
pointers, preventing potential NULL pointer dereference in clk_get_rate().

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/xe/guc: Synchronize Dead CT worker with unbind
Cancel and wait for any Dead CT worker to complete before continuing
with device unbinding. Else the worker will end up using resources freed
by the undind operation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: guard against EA inode refcount underflow in xattr update
syzkaller found a path where ext4_xattr_inode_update_ref() reads an EA
inode refcount that is already <= 0 and then applies ref_change (often
-1). That lets the refcount underflow and we proceed with a bogus value,
triggering errors like:
EXT4-fs error: EA inode <n> ref underflow: ref_count=-1 ref_change=-1
EXT4-fs warning: ea_inode dec ref err=-117
Make the invariant explicit: if the current refcount is non-positive,
treat this as on-disk corruption, emit ext4_error_inode(), and fail the
operation with -EFSCORRUPTED instead of updating the refcount. Delete the
WARN_ONCE() as negative refcounts are now impossible; keep error reporting
in ext4_error_inode().
This prevents the underflow and the follow-on orphan/cleanup churn.

Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio-net: fix received length check in big packets
Since commit 4959aebba8c0 ("virtio-net: use mtu size as buffer length
for big packets"), when guest gso is off, the allocated size for big
packets is not MAX_SKB_FRAGS * PAGE_SIZE anymore but depends on
negotiated MTU. The number of allocated frags for big packets is stored
in vi->big_packets_num_skbfrags.
Because the host announced buffer length can be malicious (e.g. the host
vhost_net driver's get_rx_bufs is modified to announce incorrect
length), we need a check in virtio_net receive path. Currently, the
check is not adapted to the new change which can lead to NULL page
pointer dereference in the below while loop when receiving length that
is larger than the allocated one.
This commit fixes the received length check corresponding to the new
change.

"value": "AV:L - The malicious input is the buffer length announced by the virtio-net backend/device over the virtqueue used-ring, not data from a network peer, so the attacker must be the local hypervisor/vhost backend or an attached virtio/vDPA device. This matches the CNA\u0027s treatment of comparable malicious-virtio-device bugs (CVE-2026-64456, CVE-2026-64490, CVE-2026-46123).\nAC:L - The same backend that announces the bogus length also controls feature negotiation and the advertised MTU, so it can deterministically create the vulnerable configuration (no MRG_RXBUF, no guest GSO, MTU \u003e 1500) and then announce any length up to MAX_SKB_FRAGS * PAGE_SIZE. No race, no memory-layout luck, and it can be repeated on every received packet.\nPR:N - The attacker acts from outside the guest\u0027s privilege model entirely \u2014 a compromised host/vhost_net or hostile virtio device holds no guest credentials and needs none, and the RX path runs unconditionally once the interface is up. Consistent with PR:N on the analogous virtio device-to-guest CVEs.\nUI:N - The corrupted length is consumed automatically in the NAPI receive path as soon as the backend completes a buffer; no guest user action is needed beyond the NIC being up.\nS:U - The vulnerable component and the impacted component are both the guest kernel \u2014 memory corruption stays within the guest\u0027s virtio-net driver and skb allocations. No IOMMU, VM, or sandbox boundary is crossed by the impact itself.\nC:H - An inflated length builds an skb whose fragments cover recycled driver pages that were never written by the device, disclosing stale kernel page contents (prior packet data) up the RX stack to guest userspace or back onto the wire, and the out-of-bounds frag-array write is memory corruption leverageable for further disclosure.\nI:H - With a backend-advertised MTU \u2265 61441, `big_packets_num_skbfrags` reaches 16 and the loop writes `skb_shinfo(skb)-\u003efrags[17]`, an out-of-bounds write of an attacker-influenced frag descriptor (size field) past the fixed `frags[MAX_SKB_FRAGS]` array into adjacent heap memory, plus corruption of `nr_frags`/`skb-\u003elen` \u2014 exactly the OOB write called out in the follow-up fix e6b8463b7d79.\nA:H - Once the page chain is exhausted, `skb_add_rx_frag()` dereferences a NULL `struct page` (`compound_head`/`page_is_pfmemalloc`) and the loop then reads `NULL-\u003eprivate`, causing a guest kernel oops in softirq context; it is trivially repeatable on every packet."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Address KCSAN report on bpf_lru_list
KCSAN reported a data-race when accessing node->ref.
Although node->ref does not have to be accurate,
take this chance to use a more common READ_ONCE() and WRITE_ONCE()
pattern instead of data_race().
There is an existing bpf_lru_node_is_ref() and bpf_lru_node_set_ref().
This patch also adds bpf_lru_node_clear_ref() to do the
WRITE_ONCE(node->ref, 0) also.

Summary
In the Linux kernel, the following vulnerability has been resolved:
audit: fix possible soft lockup in __audit_inode_child()
Tracefs or debugfs maybe cause hundreds to thousands of PATH records,
too many PATH records maybe cause soft lockup.
For example:
1. CONFIG_KASAN=y && CONFIG_PREEMPTION=n
2. auditctl -a exit,always -S open -k key
3. sysctl -w kernel.watchdog_thresh=5
4. mkdir /sys/kernel/debug/tracing/instances/test
There may be a soft lockup as follows:
watchdog: BUG: soft lockup - CPU#45 stuck for 7s! [mkdir:15498]
Kernel panic - not syncing: softlockup: hung tasks

Therefore, we add cond_resched() to __audit_inode_child() to fix it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
thermal: of: fix double-free on unregistration
Since commit 3d439b1a2ad3 ("thermal/core: Alloc-copy-free the thermal
zone parameters structure"), thermal_zone_device_register() allocates
a copy of the tzp argument and frees it when unregistering, so
thermal_of_zone_register() now ends up leaking its original tzp and
double-freeing the tzp copy. Fix this by locating tzp on stack instead.

Attacker-chosen zone geometry (trip count) further lets the freed object share `kmalloc-64` with `trips`, evading the naive freelist-hardening check.\nPR:L - Consistent with how driver-teardown and probe-unwind double frees are scored, this is treated as low-privilege rather than requiring full administrative rights; the corrupting free also occurs spontaneously on `thermal_zone_device_enable()` and devres error unwinding with no attacker privilege at all.\nUI:N - Driver unbind or module removal completes entirely without any victim action, and the probe/devres error-unwind variant needs no interaction whatsoever.\nS:U - The corruption stays inside the kernel\u0027s slab allocator and the compromise remains within the kernel\u0027s own security authority.

Per kernel scoring guidance, memory corruption of this class is High confidentiality impact.\nI:H - The double free yields a classic freelist-corruption write primitive \u2014 the attacker can reclaim the aliased object with an attacker-controlled structure and overwrite kernel state, enabling control-flow hijack and privilege escalation. Out-of-band writes through a confused type are unbounded.\nA:H - With `CONFIG_SLAB_FREELIST_HARDENED` the second free hits `BUG_ON(object == fp)`, and with `SLUB_DEBUG`/KASAN it raises a fatal \"double free\" report \u2014 either way a kernel panic. Even undetected, the corrupted freelist reliably crashes the system shortly afterward."

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-multipath: defer partition scanning
We need to suppress the partition scan from occuring within the
controller's scan_work context. If a path error occurs here, the IO will
wait until a path becomes available or all paths are torn down, but that
action also occurs within scan_work, so it would deadlock. Defer the
partion scan to a different context that does not block scan_work.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: SVM: Don't skip unrelated instruction if INT3/INTO is replaced
When re-injecting a soft interrupt from an INT3, INT0, or (select) INTn
instruction, discard the exception and retry the instruction if the code
stream is changed (e.g. by a different vCPU) between when the CPU
executes the instruction and when KVM decodes the instruction to get the
next RIP.
As effectively predicted by commit 6ef88d6e36c2 ("KVM: SVM: Re-inject
INT3/INTO instead of retrying the instruction"), failure to verify that
the correct INTn instruction was decoded can effectively clobber guest
state due to decoding the wrong instruction and thus specifying the
wrong next RIP.
The bug most often manifests as "Oops: int3" panics on static branch
checks in Linux guests. Enabling or disabling a static branch in Linux
uses the kernel's "text poke" code patching mechanism. To modify code
while other CPUs may be executing that code, Linux (temporarily)
replaces the first byte of the original instruction with an int3 (opcode
0xcc), then patches in the new code stream except for the first byte,
and finally replaces the int3 with the first byte of the new code
stream. If a CPU hits the int3, i.e. executes the code while it's being
modified, then the guest kernel must look up the RIP to determine how to
handle the #BP, e.g. by emulating the new instruction. If the RIP is
incorrect, then this lookup fails and the guest kernel panics.
The bug reproduces almost instantly by hacking the guest kernel to
repeatedly check a static branch[1] while running a drgn script[2] on
the host to constantly swap out the memory containing the guest's TSS.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: remove BUG_ON()'s in add_new_free_space()
At add_new_free_space() we have these BUG_ON()'s that are there to deal
with any failure to add free space to the in memory free space cache.
Such failures are mostly -ENOMEM that should be very rare. However there's
no need to have these BUG_ON()'s, we can just return any error to the
caller and all callers and their upper call chain are already dealing with
errors.
So just make add_new_free_space() return any errors, while removing the
BUG_ON()'s, and returning the total amount of added free space to an
optional u64 pointer argument.

Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: Log an error when close_all_cached_dirs fails
Under low-memory conditions, close_all_cached_dirs() can't move the
dentries to a separate list to dput() them once the locks are dropped.
This will result in a "Dentry still in use" error, so add an error
message that makes it clear this is what happened:
[ 495.281119] CIFS: VFS: \\otters.example.com\share Out of memory while dropping dentries
[ 495.281595] ------------[ cut here ]------------
[ 495.281887] BUG: Dentry ffff888115531138{i=78,n=/} still in use (2) [unmount of cifs cifs]
[ 495.282391] WARNING: CPU: 1 PID: 2329 at fs/dcache.c:1536 umount_check+0xc8/0xf0
Also, bail out of looping through all tcons as soon as a single
allocation fails, since we're already in trouble, and kmalloc() attempts
for subseqeuent tcons are likely to fail just like the first one did.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: fix potential race when tree connecting ipc
Protect access of TCP_Server_Info::hostname when building the ipc tree
name as it might get freed in cifsd thread and thus causing an
use-after-free bug in __tree_connect_dfs_target(). Also, while at it,
update status of IPC tcon on success and then avoid any extra tree
connects.

Both racing threads (cifsd demux thread and the cifsiod reconnect worker) run automatically over the network connection with no local component.\nAC:L - The attacker controls both sides of the race: dropping the TCP connection forces cifsd into reconnect_dfs_server()/__reconnect_target_unlocked() which kfree()s server-\u003ehostname, while the referral target list it supplies guarantees the free happens, and the cifsiod reconnect worker concurrently reads the pointer unlocked. reconnect_dfs_server() retries in a msleep(3000) loop so the window can be hit repeatedly until it lands.\nPR:N - The attacker acts as the SMB/DFS server or as a network attacker on the connection and never authenticates to or holds any account on the victim host. The vulnerable reconnect path runs in kernel threads (cifsd and the cifsiod reconnect worker), so no privileged or unprivileged local process is needed at all.\nUI:N - Against an already-mounted DFS share \u2014 the normal persistent state for enterprise fstab/autofs mounts \u2014 the entire trigger sequence is kernel-internal: cifsd drops and re-establishes the connection and queues smb2_reconnect_server(), which reaches __tree_connect_dfs_target() with no user process and no victim action.\nS:U - The use-after-free is confined to kernel heap memory of the affected host and does not cross a virtualization, IOMMU, or sandbox boundary. Impact and vulnerable component share the same security authority.\nC:H - The freed hostname buffer is formatted with \"%s\", and string_nocheck() runs with precision -1 (`while (lim--)`), so it reads freed and reallocated heap memory unbounded until a NUL byte, copying up to ~500 bytes into the tree name, which is then transmitted to the remote attacker-controlled server in the SMB2 TREE_CONNECT request \u2014 a direct kernel heap disclosure primitive.\nI:H - This is a use-after-free on an attacker-influenced heap object; an attacker who grooms the reallocated kmalloc chunk controls the string used to build the IPC$ tree-connect request, steering the client\u0027s connection state, and UAF conditions on the CIFS server/session objects are generally leverageable for stronger corruption primitives.\nA:H - The unbounded scan for a NUL over the freed allocation readily walks off the slab object into unmapped memory, producing a kernel oops/panic (and an immediate KASAN BUG on hardened kernels). The remote attacker can retrigger the reconnect race repeatedly until the client crashes."

Summary
In the Linux kernel, the following vulnerability has been resolved:
mt76: mt7615: Fix memory leak in mt7615_mcu_wtbl_sta_add()
In mt7615_mcu_wtbl_sta_add(), an skb sskb is allocated. If the
subsequent call to mt76_connac_mcu_alloc_wtbl_req() fails, the function
returns an error without freeing sskb, leading to a memory leak.
Fix this by calling dev_kfree_skb() on sskb in the error handling path
to ensure it is properly released.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/rockchip: dw_hdmi: cleanup drm encoder during unbind
This fixes a use-after-free crash during rmmod.
The DRM encoder is embedded inside the larger rockchip_hdmi,
which is allocated with the component. The component memory
gets freed before the main drm device is destroyed. Fix it
by running encoder cleanup before tearing down its container.
[moved encoder cleanup above clk_disable, similar to bind-error-path]

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommufd: IOMMUFD_DESTROY should not increase the refcount
syzkaller found a race where IOMMUFD_DESTROY increments the refcount:
obj = iommufd_get_object(ucmd->ictx, cmd->id, IOMMUFD_OBJ_ANY);
if (IS_ERR(obj))
return PTR_ERR(obj);
iommufd_ref_to_users(obj);
/* See iommufd_ref_to_users() */
if (!iommufd_object_destroy_user(ucmd->ictx, obj))
As part of the sequence to join the two existing primitives together.
Allowing the refcount the be elevated without holding the destroy_rwsem
violates the assumption that all temporary refcount elevations are
protected by destroy_rwsem. Racing IOMMUFD_DESTROY with
iommufd_object_destroy_user() will cause spurious failures:

The solution is to not increment the refcount on the IOMMUFD_DESTROY path
at all. Instead use the xa_lock to serialize everything. The refcount
check == 1 and xa_erase can be done under a single critical region. This
avoids the need for any refcount incrementing.
It has the downside that if userspace races destroy with other operations
it will get an EBUSY instead of waiting, but this is kind of racing is
already dangerous.

No root or capability check exists on `iommufd_destroy()`.\nUI:N - The attacker performs every step itself \u2014 opening the fds, binding the device, and driving both sides of the race. No victim action is involved.\nS:U - The bug only makes destroy calls fail spuriously, so objects live longer than expected; it never frees an iommu_domain while a device is still attached, so no IOMMU/DMA protection boundary is bypassed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vc_screen: reload load of struct vc_data pointer in vcs_write() to avoid UAF
After a call to console_unlock() in vcs_write() the vc_data struct can be
freed by vc_port_destruct(). Because of that, the struct vc_data pointer
must be reloaded in the while loop in vcs_write() after console_lock() to
avoid a UAF when vcs_size() is called.
Syzkaller reported a UAF in vcs_size().
BUG: KASAN: slab-use-after-free in vcs_size (drivers/tty/vt/vc_screen.c:215)

Summary
In the Linux kernel, the following vulnerability has been resolved:
hwrng: virtio - Fix race on data_avail and actual data
The virtio rng device kicks off a new entropy request whenever the
data available reaches zero. When a new request occurs at the end
of a read operation, that is, when the result of that request is
only needed by the next reader, then there is a race between the
writing of the new data and the next reader.
This is because there is no synchronisation whatsoever between the
writer and the reader.
Fix this by writing data_avail with smp_store_release and reading
it with smp_load_acquire when we first enter read. The subsequent
reads are safe because they're either protected by the first load
acquire, or by the completion mechanism.
Also remove the redundant zeroing of data_idx in random_recv_done
(data_idx must already be zero at this point) and data_avail in
request_entropy (ditto).

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-cgroup: dropping parent refcount after pd_free_fn() is done
Some cgroup policies will access parent pd through child pd even
after pd_offline_fn() is done. If pd_free_fn() for parent is called
before child, then UAF can be triggered. Hence it's better to guarantee
the order of pd_free_fn().
Currently refcount of parent blkg is dropped in __blkg_release(), which
is before pd_free_fn() is called in blkg_free_work_fn() while
blkg_free_work_fn() is called asynchronously.
This patch make sure pd_free_fn() called from removing cgroup is ordered
by delaying dropping parent refcount after calling pd_free_fn() for
child.
BTW, pd_free_fn() will also be called from blkcg_deactivate_policy()
from deleting device, and following patches will guarantee the order.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix deadlock due to mbcache entry corruption
When manipulating xattr blocks, we can deadlock infinitely looping
inside ext4_xattr_block_set() where we constantly keep finding xattr
block for reuse in mbcache but we are unable to reuse it because its
reference count is too big. This happens because cache entry for the
xattr block is marked as reusable (e_reusable set) although its
reference count is too big. When this inconsistency happens, this
inconsistent state is kept indefinitely and so ext4_xattr_block_set()
keeps retrying indefinitely.
The inconsistent state is caused by non-atomic update of e_reusable bit.
e_reusable is part of a bitfield and e_reusable update can race with
update of e_referenced bit in the same bitfield resulting in loss of one
of the updates. Fix the problem by using atomic bitops instead.
This bug has been around for many years, but it became *much* easier
to hit after commit 65f8b80053a1 ("ext4: fix race when reusing xattr
blocks").

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix memory leak in lpfc_create_port()
Commit 5e633302ace1 ("scsi: lpfc: vmid: Add support for VMID in mailbox
command") introduced allocations for the VMID resources in
lpfc_create_port() after the call to scsi_host_alloc(). Upon failure on the
VMID allocations, the new code would branch to the 'out' label, which
returns NULL without unwinding anything, thus skipping the call to
scsi_host_put().
Fix the problem by creating a separate label 'out_free_vmid' to unwind the
VMID resources and make the 'out_put_shost' label call only
scsi_host_put(), as was done before the introduction of allocations for
VMID.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix race when deleting quota root from the dirty cow roots list
When disabling quotas we are deleting the quota root from the list
fs_info->dirty_cowonly_roots without taking the lock that protects it,
which is struct btrfs_fs_info::trans_lock. This unsynchronized list
manipulation may cause chaos if there's another concurrent manipulation
of this list, such as when adding a root to it with
ctree.c:add_root_to_dirty_list().
This can result in all sorts of weird failures caused by a race, such as
the following crash:

So fix this by locking struct btrfs_fs_info::trans_lock before deleting
the quota root from that list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: avoid suspicious RCU usage for synced VLAN-aware MAC addresses
When using the felix driver (the only one which supports UC filtering
and MC filtering) as a DSA master for a random other DSA switch, one can
see the following stack trace when the downstream switch ports join a
VLAN-aware bridge:
=============================
WARNING: suspicious RCU usage
-----------------------------
net/8021q/vlan_core.c:238 suspicious rcu_dereference_protected() usage!
stack backtrace:
Workqueue: dsa_ordered dsa_slave_switchdev_event_work
Call trace:
lockdep_rcu_suspicious+0x170/0x210
vlan_for_each+0x8c/0x188
dsa_slave_sync_uc+0x128/0x178
__hw_addr_sync_dev+0x138/0x158
dsa_slave_set_rx_mode+0x58/0x70
__dev_set_rx_mode+0x88/0xa8
dev_uc_add+0x74/0xa0
dsa_port_bridge_host_fdb_add+0xec/0x180
dsa_slave_switchdev_event_work+0x7c/0x1c8
process_one_work+0x290/0x568
What it's saying is that vlan_for_each() expects rtnl_lock() context and
it's not getting it, when it's called from the DSA master's ndo_set_rx_mode().
The caller of that - dsa_slave_set_rx_mode() - is the slave DSA
interface's dsa_port_bridge_host_fdb_add() which comes from the deferred
dsa_slave_switchdev_event_work().
We went to great lengths to avoid the rtnl_lock() context in that call
path in commit 0faf890fc519 ("net: dsa: drop rtnl_lock from
dsa_slave_switchdev_event_work"), and calling rtnl_lock() is simply not
an option due to the possibility of deadlocking when calling
dsa_flush_workqueue() from the call paths that do hold rtnl_lock() -
basically all of them.
So, when the DSA master calls vlan_for_each() from its ndo_set_rx_mode(),
the state of the 8021q driver on this device is really not protected
from concurrent access by anything.
Looking at net/8021q/, I don't think that vlan_info->vid_list was
particularly designed with RCU traversal in mind, so introducing an RCU
read-side form of vlan_for_each() - vlan_for_each_rcu() - won't be so
easy, and it also wouldn't be exactly what we need anyway.
In general I believe that the solution isn't in net/8021q/ anyway;
vlan_for_each() is not cut out for this task. DSA doesn't need rtnl_lock()
to be held per se - since it's not a netdev state change that we're
blocking, but rather, just concurrent additions/removals to a VLAN list.
We don't even need sleepable context - the callback of vlan_for_each()
just schedules deferred work.
The proposed escape is to remove the dependency on vlan_for_each() and
to open-code a non-sleepable, rtnl-free alternative to that, based on
copies of the VLAN list modified from .ndo_vlan_rx_add_vid() and
.ndo_vlan_rx_kill_vid().

Driving that learning requires being on the same layer-2 segment as the switch appliance, so the reach is adjacent, not routed-network.\nAC:H - The attacker can execute the unsynchronized `vid_list` walk at arbitrary rate via MAC flooding, but the freeing side (`__vlan_vid_del()` from `dsa_port_host_vlan_add/del`) only runs during rtnl-held VLAN reconfiguration, which is outside the attacker\u0027s control. Winning the use-after-free therefore depends on a condition the attacker cannot induce.\nPR:N - No credentials or account on the target are needed \u2014 the vulnerable path is entered purely by the bridge learning attacker-supplied source MAC addresses off the wire and offloading them as host FDB entries. The attacker never issues a syscall on the device.\nUI:N - The FDB learning, switchdev notification and deferred work all occur automatically on frame reception; no operator action is required once the device is in its normal bridged/VLAN-aware configuration.\nS:U - The corrupted state (`vlan_info-\u003evid_list`) and the resulting fault are both inside the kernel, the same security authority that is compromised. No hypervisor, IOMMU or sandbox boundary is crossed.\nC:H - Traversing a `list_del`\u0027d-and-`kfree`\u0027d `vlan_vid_info` is a use-after-free read: the stale `list.next` sends the walk into reallocated or arbitrary kernel memory, and the harvested `vid`/`proto` values are programmed as host FDB/MDB filters, which can also punt traffic from VLANs the host was isolated from. Per UAF guidance this is High.\nI:H - The use-after-free lets reallocated heap contents dictate control flow of the list walk and the VLAN IDs written into the switch\u0027s hardware forwarding tables, corrupting VLAN isolation; UAFs of this class are treated as High integrity impact since heap grooming turns them into corruption primitives.\nA:H - Even absent the race the path unconditionally fires `ASSERT_RTNL()`\u0027s `WARN_ONCE` (a panic under panic_on_warn) plus a lockdep RCU splat, and dereferencing a freed or LIST_POISON\u0027d `next` pointer oopses the kernel in workqueue context, taking down the switch appliance."

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: account for current allocated stack depth in widen_imprecise_scalars()
The usage pattern for widen_imprecise_scalars() looks as follows:
prev_st = find_prev_entry(env, ...);
queued_st = push_stack(...);
widen_imprecise_scalars(env, prev_st, queued_st);
Where prev_st is an ancestor of the queued_st in the explored states
tree. This ancestor is not guaranteed to have same allocated stack
depth as queued_st. E.g. in the following case:
def main():
for i in 1..2:
foo(i) // same callsite, differnt param
def foo(i):
if i == 1:
use 128 bytes of stack
iterator based loop
Here, for a second 'foo' call prev_st->allocated_stack is 128,
while queued_st->allocated_stack is much smaller.
widen_imprecise_scalars() needs to take this into account and avoid
accessing bpf_verifier_state->frame[*]->stack out of bounds.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: sunplus: fix return value check of mmc_add_host()
mmc_add_host() may return error, if we ignore its return value,
1. the memory allocated in mmc_alloc_host() will be leaked
2. null-ptr-deref will happen when calling mmc_remove_host()
in remove function spmmc_drv_remove() because deleting not
added device.
Fix this by checking the return value of mmc_add_host(). Moreover,
I fixed the error handling path of spmmc_drv_probe() to clean up.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix the error "trying to register non-static key in rxe_cleanup_task"
In the function rxe_create_qp(), rxe_qp_from_init() is called to
initialize qp, internally things like rxe_init_task are not setup until
rxe_qp_init_req().
If an error occurred before this point then the unwind will call
rxe_cleanup() and eventually to rxe_qp_do_cleanup()/rxe_cleanup_task()
which will oops when trying to access the uninitialized spinlock.
If rxe_init_task is not executed, rxe_cleanup_task will not be called.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/amd: Add a length limitation for the ivrs_acpihid command-line parameter
The 'acpiid' buffer in the parse_ivrs_acpihid function may overflow,
because the string specifier in the format string sscanf()
has no width limitation.
Found by InfoTeCS on behalf of Linux Verification Center
(linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dlink: handle copy_thresh allocation failure
The driver did not handle failure of `netdev_alloc_skb_ip_align()`.
If the allocation failed, dereferencing `skb->protocol` could lead to
a NULL pointer dereference.
This patch tries to allocate `skb`. If the allocation fails, it falls
back to the normal path.
Tested-on: D-Link DGE-550T Rev-A3

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dp: Drop aux devices together with DP controller
Using devres to depopulate the aux bus made sure that upon a probe
deferral the EDP panel device would be destroyed and recreated upon next
attempt.
But the struct device which the devres is tied to is the DPUs
(drm_dev->dev), which may be happen after the DP controller is torn
down.
Indications of this can be seen in the commonly seen EDID-hexdump full
of zeros in the log, or the occasional/rare KASAN fault where the
panel's attempt to read the EDID information causes a use after free on
DP resources.
It's tempting to move the devres to the DP controller's struct device,
but the resources used by the device(s) on the aux bus are explicitly
torn down in the error path. The KASAN-reported use-after-free also
remains, as the DP aux "module" explicitly frees its devres-allocated
memory in this code path.
As such, explicitly depopulate the aux bus in the error path, and in the
component unbind path, to avoid these issues.

Summary
In the Linux kernel, the following vulnerability has been resolved:
isdn: mISDN: hfcsusb: fix memory leak in hfcsusb_probe()
In hfcsusb_probe(), the memory allocated for ctrl_urb gets leaked when
setup_instance() fails with an error code. Fix that by freeing the urb
before freeing the hw structure. Also change the error paths to use the
goto ladder style.
Compile tested only. Issue found using a prototype static analysis tool.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: tuners: qt1010: replace BUG_ON with a regular error
BUG_ON is unnecessary here, and in addition it confuses smatch.
Replacing this with an error return help resolve this smatch

Summary
In the Linux kernel, the following vulnerability has been resolved:
erofs: stop parsing non-compact HEAD index if clusterofs is invalid
Syzbot generated a crafted image [1] with a non-compact HEAD index of
clusterofs 33024 while valid numbers should be 0 ~ lclustersize-1,
which causes the following unexpected behavior as below:
BUG: unable to handle page fault for address: fffff52101a3fff9
#PF: supervisor read access in kernel mode
#PF: error_code(0x0000) - not-present page
PGD 23ffed067 P4D 23ffed067 PUD 0
Oops: 0000 [#1] PREEMPT SMP KASAN

"value": "AV:L - The vulnerability is triggered by parsing a crafted EROFS on-disk compression index, which requires the malicious image to be mounted on the local system (block device, loop device, or fscache-backed layer); the kernel never processes this data directly from a network protocol.\nAC:L - The clusterofs field is fully attacker-controlled in the image and the corrupted mapping is deterministically consumed on the first read of the crafted file; there is no race, timing, or memory-layout condition outside the attacker\u0027s control.\nPR:N - The attacker only needs to supply the crafted EROFS image (USB media, container/OCI layer, downloaded partition image) and requires no account or privilege on the target; the mount itself is performed by the victim\u0027s privileged user or automounter.\nUI:R - A user or an automount/container-runtime daemon must mount the attacker-supplied EROFS image, since erofs lacks FS_USERNS_MOUNT and cannot be mounted by the attacker directly; after mounting, any read of the crafted file triggers the bug with no further interaction.\nS:U - The out-of-bounds read and write occur in kernel memory within the same security authority as the kernel filesystem code; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The wrapped page index causes z_erofs_fill_other_copies() to kmap an out-of-bounds pointer and memcpy wild kernel memory into a page that is returned to userspace, giving an arbitrary kernel-memory disclosure primitive.\nI:H - When the out-of-bounds slot reads as NULL, z_erofs_do_decompressed_bvec() writes a valid struct page pointer to an attacker-influenced index far past the decompressed_pages array \u2014 an OOB write onto the erofs worker\u0027s kernel stack or adjacent heap, which is exploitable for control-flow corruption.\nA:H - The syzbot reproducer shows an unhandled page fault and oops in z_erofs_decompress_queue running in the erofs_worker kthread, and the OOB write reliably corrupts kernel memory, causing a panic."

Summary
In the Linux kernel, the following vulnerability has been resolved:
rpl: Fix use-after-free in rpl_do_srh_inline().
Running lwt_dst_cache_ref_loop.sh in selftest with KASAN triggers
the splat below [0].
rpl_do_srh_inline() fetches ipv6_hdr(skb) and accesses it after
skb_cow_head(), which is illegal as the header could be freed then.
Let's fix it by making oldhdr to a local struct instead of a pointer.
[0]:
[root@fedora net]# ./lwt_dst_cache_ref_loop.sh

Summary
In the Linux kernel, the following vulnerability has been resolved:
cacheinfo: Fix shared_cpu_map to handle shared caches at different levels
The cacheinfo sets up the shared_cpu_map by checking whether the caches
with the same index are shared between CPUs. However, this will trigger
slab-out-of-bounds access if the CPUs do not have the same cache hierarchy.
Another problem is the mismatched shared_cpu_map when the shared cache does
not have the same index between CPUs.
CPU0 I D L3
index 0 1 2 x
^ ^ ^ ^
index 0 1 2 3
CPU1 I D L2 L3
This patch checks each cache is shared with all caches on other CPUs.

In the Linux kernel, the following vulnerability has been resolved:
net: hns3: fix deadlock issue when externel_lb and reset are executed together
When externel_lb and reset are executed together, a deadlock may
occur:

In externel_lb process, the hns3 driver call napi_disable()
first, then the reset happen, then the restore process of the
externel_lb will fail, and will not call napi_enable(). When
doing externel_lb again, napi_disable() will be double call,
cause a deadlock of rtnl_lock().
This patch use the HNS3_NIC_STATE_DOWN state to protect the
calling of napi_disable() and napi_enable() in externel_lb
process, just as the usage in ndo_stop() and ndo_start().

Summary
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: double free xprt_ctxt while still in use
When an RPC request is deferred, the rq_xprt_ctxt pointer is moved out
of the svc_rqst into the svc_deferred_req.
When the deferred request is revisited, the pointer is copied into
the new svc_rqst - and also remains in the svc_deferred_req.
In the (rare?) case that the request is deferred a second time, the old
svc_deferred_req is reused - it still has all the correct content.
However in that case the rq_xprt_ctxt pointer is NOT cleared so that
when xpo_release_xprt is called, the ctxt is freed (UDP) or possible
added to a free list (RDMA).
When the deferred request is revisited for a second time, it will
reference this ctxt which may be invalid, and the free the object a
second time which is likely to oops.
So change svc_defer() to *always* clear rq_xprt_ctxt, and assert that
the value is now stored in the svc_deferred_req.

Per UAF guidance this is High.\nI:H - A double free of an sk_buff lets a remote attacker who reallocates the slot with sprayed packet data control fields such as skb-\u003edestructor and skb-\u003ehead, yielding arbitrary write / control-flow hijack; the RDMA variant double-adds a recv ctxt to the free list so two live receives share one DMA buffer.\nA:H - The commit itself notes the second free \"is likely to oops\"; a double free of an sk_buff or corruption of the RDMA recv ctxt free list panics the kernel and can be re-triggered repeatedly by an unauthenticated remote client."

In the Linux kernel, the following vulnerability has been resolved:
fbcon: Set fb_display[i]->mode to NULL when the mode is released
Recently, we discovered the following issue through syzkaller:
BUG: KASAN: slab-use-after-free in fb_mode_is_equal+0x285/0x2f0
Read of size 4 at addr ff11000001b3c69c by task syz.xxx
...

Based on experimentation and analysis, during framebuffer unregistration,
only the memory of fb_info->modelist is freed, without setting the
corresponding fb_display[i]->mode to NULL for the freed modes. This leads
to UAF issues during subsequent accesses. Here's an example of reproduction
steps:
1. With /dev/fb0 already registered in the system, load a kernel module
to register a new device /dev/fb1;
2. Set fb1's mode to the global fb_display[] array (via FBIOPUT_CON2FBMAP);
3. Switch console from fb to VGA (to allow normal rmmod of the ko);
4. Unload the kernel module, at this point fb1's modelist is freed, leaving
a wild pointer in fb_display[];
5. Trigger the bug via system calls through fb0 attempting to delete a mode
from fb0.
Add a check in do_unregister_framebuffer(): if the mode to be freed exists
in fb_display[], set the corresponding mode pointer to NULL.

There is no remote or network-facing path into fbcon.\nAC:L - Once a framebuffer has been unregistered leaving a stale `fb_display[i].mode`, triggering the use-after-free is a single deterministic ioctl with no race to win and no memory-layout condition outside the attacker\u0027s control. The attacker can additionally groom the freed `fb_modelist` slab with controlled allocations before dereferencing it.\nPR:L - No capability check exists anywhere in the fbdev ioctl path \u2014 access is governed solely by DAC on `/dev/fbN`, which logged-in seat users obtain via logind `uaccess` ACLs or `video`/`graphics` group membership on desktops, kiosks, embedded devices and Android. An unprivileged local user with a console/seat can issue every ioctl involved.\nUI:N - The attacker performs all steps himself via ioctls on the framebuffer device; no victim action is needed. The framebuffer unregistration that creates the stale pointer occurs through ordinary system events such as USB display/dock removal or DRM driver unbind.\nS:U - The corruption and its consequences are confined to kernel memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The use-after-free reads a freed slab object that the attacker can reallocate with chosen or sensitive kernel data, and `display_to_var()`/`fb_videomode_to_var()` copy ~15 fields out of it into `info-\u003evar`, which is then readable from userspace via `FBIOGET_VSCREENINFO` \u2014 a repeatable kernel heap disclosure primitive.\nI:H - A use-after-free on a groomable kmalloc object permits heap spraying and type confusion with the reallocated victim object; the freed contents also propagate into `fb_check_var`/`fb_set_par` and console resize arithmetic, corrupting kernel state and enabling escalation to control-flow hijack.\nA:H - The reported syzkaller report is a KASAN slab-use-after-free that oopses the task in `fb_mode_is_equal()`; dereferencing the dangling pointer after the slab page is returned to the page allocator produces a kernel panic, and the stale pointer can be re-triggered repeatedly."

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: hisilicon/zip - fix mismatch in get/set sgl_sge_nr
KASAN reported this Bug:
[17619.659757] BUG: KASAN: global-out-of-bounds in param_get_int+0x34/0x60
[17619.673193] Read of size 4 at addr fffff01332d7ed00 by task read_all/1507958
...
[17619.698934] The buggy address belongs to the variable:
[17619.708371] sgl_sge_nr+0x0/0xffffffffffffa300 [hisi_zip]
There is a mismatch in hisi_zip when get/set the variable sgl_sge_nr.
The type of sgl_sge_nr is u16, and get/set sgl_sge_nr by
param_get/set_int.
Replacing param_get/set_int to param_get/set_ushort can fix this bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: fix potential use-after-free bugs in TCP_Server_Info::hostname
TCP_Server_Info::hostname may be updated once or many times during
reconnect, so protect its access outside reconnect path as well and
then prevent any potential use-after-free bugs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: populate subvp cmd info only for the top pipe
[Why]
System restart observed while changing the display resolution
to 8k with extended mode. Sytem restart was caused by a page fault.
[How]
When the driver populates subvp info it did it for both the pipes using
vblank which caused an outof bounds array access causing the page fault.
added checks to allow the top pipe only to fix this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
acct: fix potential integer overflow in encode_comp_t()
The integer overflow is descripted with following codes:
> 317 static comp_t encode_comp_t(u64 value)
> 318 {
> 319 int exp, rnd;
......
> 341 exp <<= MANTSIZE;
> 342 exp += value;
> 343 return exp;
> 344 }
Currently comp_t is defined as type of '__u16', but the variable 'exp' is
type of 'int', so overflow would happen when variable 'exp' in line 343 is
greater than 65535.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: fix session state check in reconnect to avoid use-after-free issue
Don't collect exiting session in smb2_reconnect_server(), because it
will be released soon.
Note that the exiting session will stay in server->smb_ses_list until
it complete the cifs_free_ipc() and logoff() and then delete itself
from the list.

A malicious/compromised file server or an on-path attacker triggers it purely over TCP/445 with no local access.\nAC:L - The attacker controls both sides of the race: it stalls the SMB2_LOGOFF response to hold the session in SES_EXITING on smb_ses_list for the full response timeout, while forcing smb2_reconnect_server() to run on demand and repeatedly (it also self-requeues every 2 seconds), making the window trivially wide and the hit near-certain.\nPR:N - No credentials or privileges on the victim system are required \u2014 the attacker is the remote server (or an on-path attacker) acting against an existing mount, and the triggering conditions are protocol-level responses that require no authenticated privilege on the client.\nUI:N - Against an already-established mount (fstab, autofs, systemd automount, container share) the attack proceeds with no victim action; the session teardown side is generated by normal client activity such as DFS referral handling and session churn that the attacker itself induces.\nS:U - The freed and reused objects (struct cifs_ses, struct cifs_tcon) and the resulting corruption all live within the kernel\u0027s own security authority, with no crossing into a hypervisor, IOMMU, or other security scope.\nC:H - A use-after-free on a heap-allocated cifs_ses/cifs_tcon lets the attacker groom the freed slab and have the reconnect path read session fields (Suid, auth_key.response, chans[], dfs_root_ses) out of attacker-influenced memory, yielding a kernel information-disclosure primitive.\nI:H - The worker writes into the freed objects \u2014 list_add_tail() stores two pointers into ses-\u003erlist and the freed tcon_ipc-\u003erlist, ses_count is incremented through a dangling dfs_root_ses pointer, and cifs_setup_session() writes ses_status/Suid and frees ses-\u003eauth_key.response \u2014 giving write and controlled-free primitives usable for control-flow hijack.\nA:H - The use-after-free reliably corrupts kernel memory, taking spinlocks and mutexes inside a freed allocation and corrupting list heads, which oopses or panics the machine and can hang the cifs workqueue."

Summary
In the Linux kernel, the following vulnerability has been resolved:
perf/x86/intel/uncore: Fix reference count leak in snr_uncore_mmio_map()
pci_get_device() will increase the reference count for the returned
pci_dev, so snr_uncore_get_mc_dev() will return a pci_dev with its
reference count increased. We need to call pci_dev_put() to decrease the
reference count. Let's add the missing pci_dev_put().

"value": "AV:A - The vulnerable object is a Bluetooth SCO connection whose teardown half of the race (`hci_conn_failed`/`sco_connect_cfm`/`sco_disconn_cfm` on the hci_cmd_sync workqueue) is driven by link-layer events an in-range Bluetooth device controls, and the dangling `conn-\u003esk` is also consumed by the remote-fed `sco_recv_frame()` path. Per kernel guidance, Bluetooth-reachable bugs are Adjacent.\nAC:L - The attacker controls both sides of the race \u2014 the unlocked `sk_state` check in `sco_sock_connect()` lets concurrent connect()/close() calls on one socket deterministically leave a stale `conn-\u003esk`, and connection aborts can be forced at will by connecting to an unresponsive bdaddr or by a nearby device dropping the (e)SCO link. The sequence can be looped indefinitely until it wins.\nPR:L - No capability check exists in `bt_sock_create()`, `sco_sock_create()`, `sco_sock_bind()` or `sco_sock_connect()`, so any unprivileged local process can create, connect and close SCO sockets to drive the socket-lifecycle side of the race. Only basic user-level access is required.\nUI:N - Exploitation needs only socket syscalls plus Bluetooth link events; no victim action such as pairing confirmation, mounting or opening a file is required.\nS:U - The use-after-free corrupts kernel slab memory within the same kernel security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:H - The dangling `conn-\u003esk` is dereferenced in `sco_conn_ready()`, `sco_recv_frame()` and `sco_sock_hold()`, letting an attacker who reclaims the freed sock slot read and exfiltrate reclaimed kernel data (e.g. via `sock_queue_rcv_skb()` into a groomed object), giving arbitrary kernel-memory disclosure potential.\nI:H - `sco_conn_free()` performs an 8-byte write at a fixed offset into the freed allocation, and `sco_conn_ready()` makes an indirect call through `sk-\u003esk_state_change` on the freed sock \u2014 together a write primitive plus control-flow hijack enabling privilege escalation.\nA:H - Even unexploited, the slab-use-after-free corrupts kernel memory and reliably produces a KASAN splat/oops or panic, and the corrupted refcounts and pointers can hang or crash the Bluetooth stack and the system."

Summary
In the Linux kernel, the following vulnerability has been resolved:
pcmcia: rsrc_nonstatic: Fix memory leak in nonstatic_release_resource_db()
When nonstatic_release_resource_db() frees all resources associated
with an PCMCIA socket, it forgets to free socket_data too, causing
a memory leak observable with kmemleak:
unreferenced object 0xc28d1000 (size 64):
comm "systemd-udevd", pid 297, jiffies 4294898478 (age 194.484s)
hex dump (first 32 bytes):

Fix this by freeing socket_data too.
Tested on a Acer Travelmate 4002WLMi by manually binding/unbinding
the yenta_cardbus driver (yenta_socket).

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: tx-macro: Fix for KASAN: slab-out-of-bounds
When we run syzkaller we get below Out of Bound.
"KASAN: slab-out-of-bounds Read in regcache_flat_read"
Below is the backtrace of the issue:
dump_backtrace+0x0/0x4c8
show_stack+0x34/0x44
dump_stack_lvl+0xd8/0x118
print_address_description+0x30/0x2d8

snd_soc_component_update_bits+0xa8/0x22c
snd_soc_component_write_field+0x68/0xd4
tx_macro_digital_mute+0xec/0x140
Actually There is no need to have decimator with 32 bits.
By limiting the variable with short type u8 issue is resolved.

Summary
In the Linux kernel, the following vulnerability has been resolved:
regmap-irq: Fix out-of-bounds access when allocating config buffers
When allocating the 2D array for handling IRQ type registers in
regmap_add_irq_chip_fwnode(), the intent is to allocate a matrix
with num_config_bases rows and num_config_regs columns.
This is currently handled by allocating a buffer to hold a pointer for
each row (i.e. num_config_bases). After that, the logic attempts to
allocate the memory required to hold the register configuration for
each row. However, instead of doing this allocation for each row
(i.e. num_config_bases allocations), the logic erroneously does this
allocation num_config_regs number of times.
This scenario can lead to out-of-bounds accesses when num_config_regs
is greater than num_config_bases. Fix this by updating the terminating
condition of the loop that allocates the memory for holding the register
configuration to allocate memory only for each row in the matrix.
Amit Pundir reported a crash that was occurring on his db845c device
due to memory corruption (see "Closes" tag for Amit's report). The KASAN
report below helped narrow it down to this issue:

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: MGMT: cancel mesh send timer when hdev removed
mesh_send_done timer is not canceled when hdev is removed, which causes
crash if the timer triggers after hdev is gone.
Cancel the timer when MGMT removes the hdev, like other MGMT timers.
Should fix the BUG: sporadically seen by BlueZ test bot
(in "Mesh - Send cancel - 1" test).

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: stream: purge sk_error_queue in sk_stream_kill_queues()
Changheon Lee reported TCP socket leaks, with a nice repro.
It seems we leak TCP sockets with the following sequence:
1) SOF_TIMESTAMPING_TX_ACK is enabled on the socket.
Each ACK will cook an skb put in error queue, from __skb_tstamp_tx().
__skb_tstamp_tx() is using skb_clone(), unless
SOF_TIMESTAMPING_OPT_TSONLY was also requested.
2) If the application is also using MSG_ZEROCOPY, then we put in the
error queue cloned skbs that had a struct ubuf_info attached to them.
Whenever an struct ubuf_info is allocated, sock_zerocopy_alloc()
does a sock_hold().
As long as the cloned skbs are still in sk_error_queue,
socket refcount is kept elevated.
3) Application closes the socket, while error queue is not empty.
Since tcp_close() no longer purges the socket error queue,
we might end up with a TCP socket with at least one skb in
error queue keeping the socket alive forever.
This bug can be (ab)used to consume all kernel memory
and freeze the host.
We need to purge the error queue, with proper synchronization
against concurrent writers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: enetc: fix the deadlock of enetc_mdio_lock
After applying the workaround for err050089, the LS1028A platform
experiences RCU stalls on RT kernel. This issue is caused by the
recursive acquisition of the read lock enetc_mdio_lock. Here list some
of the call stacks identified under the enetc_poll path that may lead to
a deadlock:
enetc_poll
-> enetc_lock_mdio
-> enetc_clean_rx_ring OR napi_complete_done
-> napi_gro_receive
-> enetc_start_xmit
-> enetc_lock_mdio
-> enetc_map_tx_buffs
-> enetc_unlock_mdio
-> enetc_unlock_mdio
After enetc_poll acquires the read lock, a higher-priority writer attempts
to acquire the lock, causing preemption. The writer detects that a
read lock is already held and is scheduled out. However, readers under
enetc_poll cannot acquire the read lock again because a writer is already
waiting, leading to a thread hang.
Currently, the deadlock is avoided by adjusting enetc_lock_mdio to prevent
recursive lock acquisition.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: fix handling of zero-length records on the rx_list
Each recvmsg() call must process either
- only contiguous DATA records (any number of them)
- one non-DATA record
If the next record has different type than what has already been
processed we break out of the main processing loop. If the record
has already been decrypted (which may be the case for TLS 1.3 where
we don't know type until decryption) we queue the pending record
to the rx_list. Next recvmsg() will pick it up from there.
Queuing the skb to rx_list after zero-copy decrypt is not possible,
since in that case we decrypted directly to the user space buffer,
and we don't have an skb to queue (darg.skb points to the ciphertext
skb for access to metadata like length).
Only data records are allowed zero-copy, and we break the processing
loop after each non-data record. So we should never zero-copy and
then find out that the record type has changed. The corner case
we missed is when the initial record comes from rx_list, and it's
zero length.

TLS 1.2 is zero-copy-capable by default (zc_capable = rx_no_pad || version != TLS_1_3_VERSION), so no unusual kernel config or sockopt is required.\nPR:N - The attacker is the remote TLS peer, which holds no privileges on the target system \u2014 an anonymous client completing a server-authenticated TLS handshake with a kTLS server, or a malicious server that a kTLS client connects to, suffices. This matches the repo\u0027s PR:N scoring of the comparable remote-peer net/tls bug CVE-2025-39946.\nUI:N - The victim application only has to run its normal recvmsg() loop on an already-established kTLS socket; no click, mount, file open, or any other victim action is required.

Standard in-kernel memory corruption is Scope:Unchanged.\nC:H - The strparser anchor is queued on rx_list after tcp_read_done() already released its backing TCP skbs, so the next recvmsg() copies freed kernel heap memory straight into the userspace buffer via skb_copy_datagram_msg(). This is a directly usable, repeatable kernel-memory disclosure primitive, not a bounded pointer leak.\nI:H - The live strp-\u003eanchor is consume_skb()\u0027d by process_rx_list() while the strparser still uses it, after which incoming attacker-controlled TCP data is written into the freed sk_buff/skb_shared_info (skb_fill_page_desc, tls_strp_load_anchor_with_queue), and socket teardown double-frees the anchor and its frag_list skbs. This yields attacker-controlled write-after-free and freelist corruption suitable for control-flow hijack.\nA:H - The use-after-free and double-free of the anchor and of already-released TCP receive-queue skbs reliably corrupt slab state, producing oopses/panics and list corruption. Any remote peer can repeat this on every connection, giving a trivial remote kernel-crash DoS."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix gpu page fault after hibernation on PF passthrough
On PF passthrough environment, after hibernate and then resume, coralgemm
will cause gpu page fault.
Mode1 reset happens during hibernate, but partition mode is not restored
on resume, register mmCP_HYP_XCP_CTL and mmCP_PSP_XCP_CTL is not right
after resume. When CP access the MQD BO, wrong stride size is used,
this will cause out of bound access on the MQD BO, resulting page fault.
The fix is to ensure gfx_v9_4_3_switch_compute_partition() is called
when resume from a hibernation.
KFD resume is called separately during a reset recovery or resume from
suspend sequence. Hence it's not required to be called as part of
partition switch.
(cherry picked from commit 5d1b32cfe4a676fe552416cb5ae847b215463a1a)

Summary
In the Linux kernel, the following vulnerability has been resolved:
rcu: dump vmalloc memory info safely
Currently, for double invoke call_rcu(), will dump rcu_head objects memory
info, if the objects is not allocated from the slab allocator, the
vmalloc_dump_obj() will be invoke and the vmap_area_lock spinlock need to
be held, since the call_rcu() can be invoked in interrupt context,
therefore, there is a possibility of spinlock deadlock scenarios.
And in Preempt-RT kernel, the rcutorture test also trigger the following
lockdep warning:

The previous patch fixes this by using the deadlock-safe best-effort
version of find_vm_area. However, in case of failure print the fact that
the pointer was a vmalloc pointer so that we print at least something.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ima: don't clear IMA_DIGSIG flag when setting or removing non-IMA xattr
Currently when both IMA and EVM are in fix mode, the IMA signature will
be reset to IMA hash if a program first stores IMA signature in
security.ima and then writes/removes some other security xattr for the
file.
For example, on Fedora, after booting the kernel with "ima_appraise=fix
evm=fix ima_policy=appraise_tcb" and installing rpm-plugin-ima,
installing/reinstalling a package will not make good reference IMA
signature generated. Instead IMA hash is generated,
# getfattr -m - -d -e hex /usr/bin/bash
# file: usr/bin/bash
security.ima=0x0404...
This happens because when setting security.selinux, the IMA_DIGSIG flag
that had been set early was cleared. As a result, IMA hash is generated
when the file is closed.
Similarly, IMA signature can be cleared on file close after removing
security xattr like security.evm or setting/removing ACL.
Prevent replacing the IMA file signature with a file hash, by preventing
the IMA_DIGSIG flag from being reset.
Here's a minimal C reproducer which sets security.selinux as the last
step which can also replaced by removing security.evm or setting ACL,
#include <stdio.h>
#include <sys/xattr.h>
#include <fcntl.h>
#include <unistd.h>
#include <string.h>
#include <stdlib.h>

No network, adjacent-network, or physical path reaches the IMA appraisal hooks.\nAC:L - The commit ships a deterministic reproducer: setting any EVM-protected xattr or a POSIX ACL unconditionally clears IMA_DIGSIG every time, with no memory-layout or timing luck involved. The enforce-mode variant needs a race against `process_measurement()`\u0027s `MAY_WRITE` check, but `ima_reset_appraise_flags()` takes no `iint-\u003emutex`, and the attacker drives both sides (one thread spinning on `setxattr(\"system.posix_acl_access\")`, another on `open(O_WRONLY)`); the required IMA-appraise + EVM configuration is a shipped, supported Fedora/RHEL setup, not a rare build option.\nPR:L - `vfs_set_acl()` invokes `security_inode_set_acl()` \u2192 `ima_inode_set_acl()` \u2192 `ima_reset_appraise_flags(inode, 0)` before `set_posix_acl()` ever reaches its `inode_owner_or_capable()` check, so an unprivileged user with no capabilities and no ownership of the file clears the cached IMA_DIGSIG bit on any signed appraised binary \u2014 the syscall fails with -EPERM only after the flag is already gone. No CAP_SYS_ADMIN is needed for this path, unlike the `security.ima` path guarded by `ima_protect_xattr()`.\nUI:N - The attacker performs the xattr/ACL operation and the file open/close entirely from their own process; no victim must mount a filesystem, open a file, or take any other action for the IMA_DIGSIG flag to be cleared and the signature to be replaced.\nS:U - The defeated control (IMA appraisal) and the affected resources (files and their security xattrs) live in the same kernel security authority; no VM, hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - Clearing IMA_DIGSIG both drops the \"signed files cannot be opened for write\" enforcement at `ima_main.c:472` and lets `ima_update_xattr()` re-bless the modified content with a fresh hash plus EVM HMAC, so attacker-substituted content in an appraised executable passes appraisal and subsequently runs \u2014 typically in a privileged/service context \u2014 yielding full disclosure of data reachable by that code. This is the standard treatment of a code-integrity/signature-verification bypass; the bug itself contains no direct memory-read primitive.\nI:H - The file\u0027s IMA digital signature \u2014 the one integrity artifact a local attacker cannot forge, since it is verified against the trusted IMA keyring \u2014 is silently destroyed and replaced by a locally computed hash written through `__vfs_setxattr_noperm()`, which bypasses the `CAP_SYS_ADMIN` gate in `ima_protect_xattr()`. Combined with the lost write-block, this converts \"signed and immutable\" into \"mutable and re-blessed on close\", a complete integrity bypass of IMA appraisal for the affected file.\nA:H - Once a signature is replaced by a plain hash, any policy carrying IMA_DIGSIG_REQUIRED (`appraise_type=imasig`) rejects that file in enforce mode, so appraised binaries become permanently unexecutable \u2014 applied to system-critical files such as init, sshd, or libc consumers this denies service and can leave the system unbootable, and the corrupted xattr persists on disk until the file is re-signed out of band."

Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: atmel-mci: fix return value check of mmc_add_host()
mmc_add_host() may return error, if we ignore its return value,
it will lead two issues:
1. The memory that allocated in mmc_alloc_host() is leaked.
2. In the remove() path, mmc_remove_host() will be called to
delete device, but it's not added yet, it will lead a kernel
crash because of null-ptr-deref in device_del().
So fix this by checking the return value and calling mmc_free_host()
in the error path.

In the Linux kernel, the following vulnerability has been resolved:
smb3: fix for slab out of bounds on mount to ksmbd
With KASAN enabled, it is possible to get a slab out of bounds
during mount to ksmbd due to missing check in parse_server_interfaces()
(see below):

A malicious or compromised SMB server (or MITM on an unsigned session) triggers it purely with network data.\nAC:L - The server directly controls the 32-bit `Next` value and the response length, so it deterministically drives `p` past the end of the kmemdup\u0027d buffer on the first entry; no race, timing, or memory-layout condition outside the attacker\u0027s control is involved.\nPR:N - The attacker is the peer SMB server, which holds no privileges on the victim client \u2014 it is the client that authenticates to the server, not the reverse. No credentials or local account on the target are needed.\nUI:N - Besides the mount path, `SMB3_request_interfaces()` is invoked from the `smb2_query_server_interfaces()` delayed work re-queued every 600 s and from `smb2_reconnect()`; since the server itself advertises the MULTI_CHANNEL capability that schedules that poll and can force a reconnect by dropping the connection, it can trigger the parse repeatedly on a pre-existing mount with no victim action.\nS:U - The invalid read and its consequences stay within the kernel of the affected client host; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The server chooses an arbitrary offset of up to 4 GiB past the response allocation, giving an unbounded wild read of kernel memory rather than a small bounded overread, consistent with kernel.org CNA treatment of cifs client OOB reads (e.g. CVE-2026-31613, CVE-2026-46155).\nI:N - The defect is strictly a read: `bytes_left` goes negative and the loop exits before any out-of-bounds bytes are copied into `tmp_iface` or the interface list, and there is no out-of-bounds write.\nA:H - Dereferencing a pointer up to 4 GiB beyond a slab object readily hits an unmapped direct-map address, producing a kernel oops that kills the mounting or cifsiod worker context (and a KASAN report/panic on hardened kernels); the server can repeat it on every reconnect."

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/powernv/sriov: perform null check on iov before dereferencing iov
Currently pointer iov is being dereferenced before the null check of iov
which can lead to null pointer dereference errors. Fix this by moving the
iov null check before the dereferencing.
Detected using cppcheck static analysis:
linux/arch/powerpc/platforms/powernv/pci-sriov.c:597:12: warning: Either
the condition '!iov' is redundant or there is possible null pointer
dereference: iov. [nullPointerRedundantCheck]
num_vfs = iov->num_vfs;

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix DMA-API call trace on NVMe LS requests
The following message and call trace was seen with debug kernels:
DMA-API: qla2xxx 0000:41:00.0: device driver failed to check map
error [device address=0x00000002a3ff38d8] [size=1024 bytes] [mapped as
single]
WARNING: CPU: 0 PID: 2930 at kernel/dma/debug.c:1017
check_unmap+0xf42/0x1990
Call Trace:
debug_dma_unmap_page+0xc9/0x100
qla_nvme_ls_unmap+0x141/0x210 [qla2xxx]
Remove DMA mapping from the driver altogether, as it is already done by FC
layer. This prevents the warning.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix pci device refcount leak
As comment of pci_get_domain_bus_and_slot() says, it returns
a pci device with refcount increment, when finish using it,
the caller must decrement the reference count by calling
pci_dev_put().
So before returning from amdgpu_device_resume|suspend_display_audio(),
pci_dev_put() is called to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: prevent infinite loop in rt6_nlmsg_size()
While testing prior patch, I was able to trigger
an infinite loop in rt6_nlmsg_size() in the following place:
list_for_each_entry_rcu(sibling, &f6i->fib6_siblings,
fib6_siblings) {
rt6_nh_nlmsg_size(sibling->fib6_nh, &nexthop_len);
}
This is because fib6_del_route() and fib6_add_rt2node()
uses list_del_rcu(), which can confuse rcu readers,
because they might no longer see the head of the list.
Restart the loop if f6i->fib6_nsiblings is zero.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: taprio: Limit TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME to INT_MAX.
syzkaller found zero division error [0] in div_s64_rem() called from
get_cycle_time_elapsed(), where sched->cycle_time is the divisor.
We have tests in parse_taprio_schedule() so that cycle_time will never
be 0, and actually cycle_time is not 0 in get_cycle_time_elapsed().
The problem is that the types of divisor are different; cycle_time is
s64, but the argument of div_s64_rem() is s32.
syzkaller fed this input and 0x100000000 is cast to s32 to be 0.
@TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME={0xc, 0x8, 0x100000000}
We use s64 for cycle_time to cast it to ktime_t, so let's keep it and
set max for cycle_time.
While at it, we prevent overflow in setup_txtime() and add another
test in parse_taprio_schedule() to check if cycle_time overflows.
Also, we add a new tdc test case for this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix incorrect splitting in btrfs_drop_extent_map_range
In production we were seeing a variety of WARN_ON()'s in the extent_map
code, specifically in btrfs_drop_extent_map_range() when we have to call
add_extent_mapping() for our second split.
Consider the following extent map layout
PINNED
[0 16K) [32K, 48K)
and then we call btrfs_drop_extent_map_range for [0, 36K), with
skip_pinned == true. The initial loop will have
start = 0
end = 36K
len = 36K
we will find the [0, 16k) extent, but since we are pinned we will skip
it, which has this code
start = em_end;
if (end != (u64)-1)
len = start + len - em_end;
em_end here is 16K, so now the values are
start = 16K
len = 16K + 36K - 16K = 36K
len should instead be 20K. This is a problem when we find the next
extent at [32K, 48K), we need to split this extent to leave [36K, 48k),
however the code for the split looks like this
split->start = start + len;
split->len = em_end - (start + len);
In this case we have
em_end = 48K
split->start = 16K + 36K // this should be 16K + 20K
split->len = 48K - (16K + 36K) // this overflows as 16K + 36K is 52K
and now we have an invalid extent_map in the tree that potentially
overlaps other entries in the extent map. Even in the non-overlapping
case we will have split->start set improperly, which will cause problems
with any block related calculations.
We don't actually need len in this loop, we can simply use end as our
end point, and only adjust start up when we find a pinned extent we need
to skip.
Adjust the logic to do this, which keeps us from inserting an invalid
extent map.
We only skip_pinned in the relocation case, so this is relatively rare,
except in the case where you are running relocation a lot, which can
happen with auto relocation on.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/mxsfb: Disable overlay plane in mxsfb_plane_overlay_atomic_disable()
When disabling overlay plane in mxsfb_plane_overlay_atomic_update(),
overlay plane's framebuffer pointer is NULL. So, dereferencing it would
cause a kernel Oops(NULL pointer dereferencing). Fix the issue by
disabling overlay plane in mxsfb_plane_overlay_atomic_disable() instead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vfio/type1: fix cap_migration information leak
Fix an information leak where an uninitialized hole in struct
vfio_iommu_type1_info_cap_migration on the stack is exposed to userspace.
The definition of struct vfio_iommu_type1_info_cap_migration contains a hole as
shown in this pahole(1) output:
struct vfio_iommu_type1_info_cap_migration {
struct vfio_info_cap_header header; /* 0 8 */
__u32 flags; /* 8 4 */
/* XXX 4 bytes hole, try to pack */
__u64 pgsize_bitmap; /* 16 8 */
__u64 max_dirty_bitmap_size; /* 24 8 */
/* size: 32, cachelines: 1, members: 4 */
/* sum members: 28, holes: 1, sum holes: 4 */
/* last cacheline: 32 bytes */
};
The cap_mig variable is filled in without initializing the hole:
static int vfio_iommu_migration_build_caps(struct vfio_iommu *iommu,
struct vfio_info_cap *caps)
{
struct vfio_iommu_type1_info_cap_migration cap_mig;
cap_mig.header.id = VFIO_IOMMU_TYPE1_INFO_CAP_MIGRATION;
cap_mig.header.version = 1;
cap_mig.flags = 0;
/* support minimum pgsize */
cap_mig.pgsize_bitmap = (size_t)1 << __ffs(iommu->pgsize_bitmap);
cap_mig.max_dirty_bitmap_size = DIRTY_BITMAP_SIZE_MAX;
return vfio_info_add_capability(caps, &cap_mig.header, sizeof(cap_mig));
}
The structure is then copied to a temporary location on the heap. At this point
it's already too late and ioctl(VFIO_IOMMU_GET_INFO) copies it to userspace
later:
int vfio_info_add_capability(struct vfio_info_cap *caps,
struct vfio_info_cap_header *cap, size_t size)
{
struct vfio_info_cap_header *header;
header = vfio_info_cap_add(caps, size, cap->id, cap->version);
if (IS_ERR(header))
return PTR_ERR(header);
memcpy(header + 1, cap + 1, size - sizeof(*header));
return 0;
}
This issue was found by code inspection.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, ktls: Fix data corruption when using bpf_msg_pop_data() in ktls
When sending plaintext data, we initially calculated the corresponding
ciphertext length. However, if we later reduced the plaintext data length
via socket policy, we failed to recalculate the ciphertext length.
This results in transmitting buffers containing uninitialized data during
ciphertext transmission.
This causes uninitialized bytes to be appended after a complete
"Application Data" packet, leading to errors on the receiving end when
parsing TLS record.

Summary
In the Linux kernel, the following vulnerability has been resolved:
exfat: fix improper check of dentry.stream.valid_size
We found an infinite loop bug in the exFAT file system that can lead to a
Denial-of-Service (DoS) condition. When a dentry in an exFAT filesystem is
malformed, the following system calls — SYS_openat, SYS_ftruncate, and
SYS_pwrite64 — can cause the kernel to hang.
Root cause analysis shows that the size validation code in exfat_find()
does not check whether dentry.stream.valid_size is negative. As a result,
the system calls mentioned above can succeed and eventually trigger the DoS
issue.
This patch adds a check for negative dentry.stream.valid_size to prevent
this vulnerability.

Summary
In the Linux kernel, the following vulnerability has been resolved:
uio: uio_dmem_genirq: Fix missing unlock in irq configuration
Commit b74351287d4b ("uio: fix a sleep-in-atomic-context bug in
uio_dmem_genirq_irqcontrol()") started calling disable_irq() without
holding the spinlock because it can sleep. However, that fix introduced
another bug: if interrupt is already disabled and a new disable request
comes in, then the spinlock is not unlocked:

('myfpga' is a simple 'uio_dmem_genirq' driver I wrote to test this)
The implementation of "uio_dmem_genirq" was based on "uio_pdrv_genirq" and
it is used in a similar manner to the "uio_pdrv_genirq" driver with respect
to interrupt configuration and handling. At the time "uio_dmem_genirq" was
introduced, both had the same implementation of the 'uio_info' handlers
irqcontrol() and handler(). Then commit 34cb27528398 ("UIO: Fix concurrency
issue"), which was only applied to "uio_pdrv_genirq", ended up making them
a little different. That commit, among other things, changed disable_irq()
to disable_irq_nosync() in the implementation of irqcontrol(). The
motivation there was to avoid a deadlock between irqcontrol() and
handler(), since it added a spinlock in the irq handler, and disable_irq()
waits for the completion of the irq handler.
By changing disable_irq() to disable_irq_nosync() in irqcontrol(), we also
avoid the sleeping-whil

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/siw: Fix immediate work request flush to completion queue
Correctly set send queue element opcode during immediate work request
flushing in post sendqueue operation, if the QP is in ERROR state.
An undefined ocode value results in out-of-bounds access to an array
for mapping the opcode between siw internal and RDMA core representation
in work completion generation. It resulted in a KASAN BUG report
of type 'global-out-of-bounds' during NFSoRDMA testing.
This patch further fixes a potential case of a malicious user which may
write undefined values for completion queue elements status or opcode,
if the CQ is memory mapped to user land. It avoids the same out-of-bounds
access to arrays for status and opcode mapping as described above.

A malicious USB device asserting the EncServ INQUIRY bit is an additional, less severe path.\nAC:L - The attacker fully controls both the page 10 length field and the page 1 element counts, so reporting a short page 10 while advertising DEVICE/ARRAY_DEVICE elements deterministically drives addl_desc_ptr past the end of the allocation on every probe. No race, timing, or uncontrolled memory-layout condition is involved.\nPR:N - ses_intf_add() runs automatically during SCSI LUN discovery/rescan and binds to any target that sets the EncServ bit in its own INQUIRY response, so no credentials or prior authorization on the host are required. The KASAN report was produced by systemd-udevd during ordinary enumeration.\nUI:N - Enclosure probing is driven by the kernel\u0027s automatic device discovery on link-up/hotplug and on session re-establishment, not by any operator action. No mount, open, or configuration step by a victim is needed.\nS:U - The out-of-bounds read stays within the kernel\u0027s own slab memory and the derived data is exposed through the kernel\u0027s own enclosure sysfs interface. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - Adjacent slab memory is read out of bounds and the bytes are retained in ecomp-\u003eslot and scomp-\u003eaddr, with slot exported through the world-readable /sys/class/enclosure/*/*/slot attribute, giving a repeatable heap-adjacency oracle usable to disclose kernel heap contents and defeat layout randomization. Repeated re-probes let the attacker sample different heap neighbours.\nI:N - The defect is strictly a read overrun \u2014 ses_process_descriptor() only loads from the descriptor and writes to in-bounds fields, so there is no out-of-bounds write or control-flow primitive. Any bogus slot/address reported is something a malicious enclosure could already report through well-formed data.\nA:H - With attacker-chosen element counts the pointer can advance up to ~257 bytes per iteration across tens of thousands of iterations, running far past the page10 allocation into unmapped frames and oopsing the kernel, and it trips a KASAN slab-out-of-bounds report that panics hosts running panic_on_warn. The attacker can force this on every discovery cycle."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: openvswitch: reject negative ifindex
Recent changes in net-next (commit 759ab1edb56c ("net: store netdevs
in an xarray")) refactored the handling of pre-assigned ifindexes
and let syzbot surface a latent problem in ovs. ovs does not validate
ifindex, making it possible to create netdev ports with negative
ifindex values. It's easy to repro with YNL:
$ ./cli.py --spec netlink/specs/ovs_datapath.yaml \
--do new \
--json '{"upcall-pid": 1, "name":"my-dp"}'
$ ./cli.py --spec netlink/specs/ovs_vport.yaml \
--do new \
--json '{"upcall-pid": "00000001", "name": "some-port0", "dp-ifindex":3,"ifindex":4294901760,"type":2}'
$ ip link show
-65536: some-port0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ether 7a:48:21:ad:0b:fb brd ff:ff:ff:ff:ff:ff
...
Validate the inputs. Now the second command correctly returns:
$ ./cli.py --spec netlink/specs/ovs_vport.yaml \
--do new \
--json '{"upcall-pid": "00000001", "name": "some-port0", "dp-ifindex":3,"ifindex":4294901760,"type":2}'
lib.ynl.NlError: Netlink error: Numerical result out of range
nl_len = 108 (92) nl_flags = 0x300 nl_type = 2
error: -34 extack: {'msg': 'integer out of range', 'unknown': [[type:4 len:36] b'\x0c\x00\x02\x00\x00\x00\x00\x00\x00\x00\x00\x00\x0c\x00\x03\x00\xff\xff\xff\x7f\x00\x00\x00\x00\x08\x00\x01\x00\x08\x00\x00\x00'], 'bad-attr': '.ifindex'}
Accept 0 since it used to be silently ignored.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: avoid potential buffer over-read in parse_apply_sb_mount_options()
Unlike other strings in the ext4 superblock, we rely on tune2fs to
make sure s_mount_opts is NUL terminated. Harden
parse_apply_sb_mount_options() by treating s_mount_opts as a potential
__nonstring.

Summary
In the Linux kernel, the following vulnerability has been resolved:
driver core: fix potential null-ptr-deref in device_add()
I got the following null-ptr-deref report while doing fault injection test:
BUG: kernel NULL pointer dereference, address: 0000000000000058
CPU: 2 PID: 278 Comm: 37-i2c-ds2482 Tainted: G B W N 6.1.0-rc3+
RIP: 0010:klist_put+0x2d/0xd0
Call Trace:
<TASK>
klist_remove+0xf1/0x1c0
device_release_driver_internal+0x196/0x210
bus_remove_device+0x1bd/0x240
device_add+0xd3d/0x1100
w1_add_master_device+0x476/0x490 [wire]
ds2482_probe+0x303/0x3e0 [ds2482]
This is how it happened:
w1_alloc_dev()
// The dev->driver is set to w1_master_driver.
memcpy(&dev->dev, device, sizeof(struct device));
device_add()
bus_add_device()
dpm_sysfs_add() // It fails, calls bus_remove_device.
// error path
bus_remove_device()
// The dev->driver is not null, but driver is not bound.
__device_release_driver()
klist_remove(&dev->p->knode_driver) <-- It causes null-ptr-deref.
// normal path
bus_probe_device() // It's not called yet.
device_bind_driver()
If dev->driver is set, in the error path after calling bus_add_device()
in device_add(), bus_remove_device() is called, then the device will be
detached from driver. But device_bind_driver() is not called yet, so it
causes null-ptr-deref while access the 'knode_driver'. To fix this, set
dev->driver to null in the error path before calling bus_remove_device().

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: Fix race condition between concurrent dwc3_remove_requests() call paths
This patch addresses a race condition caused by unsynchronized
execution of multiple call paths invoking `dwc3_remove_requests()`,
leading to premature freeing of USB requests and subsequent crashes.
Three distinct execution paths interact with `dwc3_remove_requests()`:
Path 1:
Triggered via `dwc3_gadget_reset_interrupt()` during USB reset
handling. The call stack includes:
- `dwc3_ep0_reset_state()`
- `dwc3_ep0_stall_and_restart()`
- `dwc3_ep0_out_start()`
- `dwc3_remove_requests()`
- `dwc3_gadget_del_and_unmap_request()`
Path 2:
Also initiated from `dwc3_gadget_reset_interrupt()`, but through
`dwc3_stop_active_transfers()`. The call stack includes:
- `dwc3_stop_active_transfers()`
- `dwc3_remove_requests()`
- `dwc3_gadget_del_and_unmap_request()`
Path 3:
Occurs independently during `adb root` execution, which triggers
USB function unbind and bind operations. The sequence includes:
- `gserial_disconnect()`
- `usb_ep_disable()`
- `dwc3_gadget_ep_disable()`
- `dwc3_remove_requests()` with `-ESHUTDOWN` status
Path 3 operates asynchronously and lacks synchronization with Paths
1 and 2. When Path 3 completes, it disables endpoints and frees 'out'
requests. If Paths 1 or 2 are still processing these requests,
accessing freed memory leads to a crash due to use-after-free conditions.
To fix this added check for request completion and skip processing
if already completed and added the request status for ep0 while queue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Don't clone flow post action attributes second time
The code already clones post action attributes in
mlx5e_clone_flow_attr_for_post_act(). Creating another copy in
mlx5e_tc_post_act_add() is a erroneous leftover from original
implementation. Instead, assign handle->attribute to post_attr provided by
the caller. Note that cloning the attribute second time is not just
wasteful but also causes issues like second copy not being properly updated
in neigh update code which leads to following use-after-free:

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Disable preemption in bpf_event_output
We received report [1] of kernel crash, which is caused by
using nesting protection without disabled preemption.
The bpf_event_output can be called by programs executed by
bpf_prog_run_array_cg function that disabled migration but
keeps preemption enabled.
This can cause task to be preempted by another one inside the
nesting protection and lead eventually to two tasks using same
perf_sample_data buffer and cause crashes like:
BUG: kernel NULL pointer dereference, address: 0000000000000001
#PF: supervisor instruction fetch in kernel mode
#PF: error_code(0x0010) - not-present page

Remote packets only reach this code through softirq paths where preemption is already disabled, so exploitation requires local execution.\nAC:L - The attacker controls both sides of the race \u2014 multiple threads pinned to the same CPU repeatedly invoking the helper, plus self-generated scheduling pressure to force preemption inside the unprotected nest-level window. The required preemptible kernel (CONFIG_PREEMPT/PREEMPT_DYNAMIC/PREEMPT_RT) and a perf-emitting eBPF agent are the default in Android, container, and cloud deployments.\nPR:L - Any unprivileged local process \u2014 including code confined inside a container or pod \u2014 triggers the cgroup BPF program merely by calling connect(), sendmsg(), or setsockopt(); no capability, CAP_BPF, or namespace privilege is required on the triggering side.\nUI:N - No victim action is needed; the attacker\u0027s own syscalls drive both racing invocations, and the presence of an attached eBPF monitoring program is ambient system configuration rather than user interaction.\nS:U - The corruption and its consequences are confined to the kernel\u0027s own security authority with no crossing of a hypervisor, IOMMU, or sandbox boundary. This is standard in-kernel memory corruption / privilege escalation.\nC:H - A hijacked perf_sample_data leaves sd-\u003eraw pointing at a dead kernel stack frame, so __output_copy() streams frag-\u003esize bytes from an unvalidated frag-\u003edata pointer into the perf ring buffer that userspace mmaps \u2014 an arbitrary kernel memory read primitive into attacker-readable memory.\nI:H - perf_output_sample() performs an indirect call through frag-\u003ecopy read from the stale stack frame (__output_custom), which the mainline reports observed as executing an NX-protected page and fetching instructions from address 0x1. Since the stale frame belongs to an attacker-controlled task, this is a groomable control-flow hijack primitive.\nA:H - The bug was reported from production as a hard kernel crash \u2014 NULL pointer dereference / supervisor instruction fetch oops in perf_output_sample \u2014 and can be triggered repeatedly by any local user, producing a reliable denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: meson-gx: fix return value check of mmc_add_host()
mmc_add_host() may return error, if we ignore its return value,
it will lead two issues:
1. The memory that allocated in mmc_alloc_host() is leaked.
2. In the remove() path, mmc_remove_host() will be called to
delete device, but it's not added yet, it will lead a kernel
crash because of null-ptr-deref in device_del().
Fix this by checking the return value and goto error path which
will call mmc_free_host().

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-mq: fix tags leak when shrink nr_hw_queues
Although we don't need to realloc set->tags[] when shrink nr_hw_queues,
we need to free them. Or these tags will be leaked.
How to reproduce:
1. mount -t configfs configfs /mnt
2. modprobe null_blk nr_devices=0 submit_queues=8
3. mkdir /mnt/nullb/nullb0
4. echo 1 > /mnt/nullb/nullb0/power
5. echo 4 > /mnt/nullb/nullb0/submit_queues
6. rmdir /mnt/nullb/nullb0
In step 4, will alloc 9 tags (8 submit queues and 1 poll queue), then
in step 5, new_nr_hw_queues = 5 (4 submit queues and 1 poll queue).
At last in step 6, only these 5 tags are freed, the other 4 tags leaked.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm: Prevent drm_copy_field() to attempt copying a NULL pointer
There are some struct drm_driver fields that are required by drivers since
drm_copy_field() attempts to copy them to user-space via DRM_IOCTL_VERSION.
But it can be possible that a driver has a bug and did not set some of the
fields, which leads to drm_copy_field() attempting to copy a NULL pointer:

Summary
In the Linux kernel, the following vulnerability has been resolved:
mtd: rawnand: fsl_upm: Fix an off-by one test in fun_exec_op()
'op-cs' is copied in 'fun->mchip_number' which is used to access the
'mchip_offsets' and the 'rnb_gpio' arrays.
These arrays have NAND_MAX_CHIPS elements, so the index must be below this
limit.
Fix the sanity check in order to avoid the NAND_MAX_CHIPS value. This
would lead to out-of-bound accesses.

Summary
In the Linux kernel, the following vulnerability has been resolved:
atm/fore200e: Fix possible data race in fore200e_open()
Protect access to fore200e->available_cell_rate with rate_mtx lock in the
error handling path of fore200e_open() to prevent a data race.
The field fore200e->available_cell_rate is a shared resource used to track
available bandwidth. It is concurrently accessed by fore200e_open(),
fore200e_close(), and fore200e_change_qos().
In fore200e_open(), the lock rate_mtx is correctly held when subtracting
vcc->qos.txtp.max_pcr from available_cell_rate to reserve bandwidth.
However, if the subsequent call to fore200e_activate_vcin() fails, the
function restores the reserved bandwidth by adding back to
available_cell_rate without holding the lock.
This introduces a race condition because available_cell_rate is a global
device resource shared across all VCCs. If the error path in
fore200e_open() executes concurrently with operations like
fore200e_close() or fore200e_change_qos() on other VCCs, a
read-modify-write race occurs.
Specifically, the error path reads the rate without the lock. If another
CPU acquires the lock and modifies the rate (e.g., releasing bandwidth in
fore200e_close()) between this read and the subsequent write, the error
path will overwrite the concurrent update with a stale value. This results
in incorrect bandwidth accounting.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: cros_ec_keyb - fix an invalid memory access
If cros_ec_keyb_register_matrix() isn't called (due to
`buttons_switches_only`) in cros_ec_keyb_probe(), `ckdev->idev` remains
NULL. An invalid memory access is observed in cros_ec_keyb_process()
when receiving an EC_MKBP_EVENT_KEY_MATRIX event in cros_ec_keyb_work()
in such case.
Unable to handle kernel read from unreadable memory at virtual address 0000000000000028
...
x3 : 0000000000000000 x2 : 0000000000000000
x1 : 0000000000000000 x0 : 0000000000000000
Call trace:
input_event
cros_ec_keyb_work
blocking_notifier_call_chain
ec_irq_thread
It's still unknown about why the kernel receives such malformed event,
in any cases, the kernel shouldn't access `ckdev->idev` and friends if
the driver doesn't intend to initialize them.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/radeon: Do not kfree() devres managed rdev
Since the allocation of the drivers main structure was changed to
devm_drm_dev_alloc() rdev is managed by devres and we shouldn't be calling
kfree() on it.
This fixes things exploding if the driver probe fails and devres cleans up
the rdev after we already free'd it.
(cherry picked from commit 16c0681617b8a045773d4d87b6140002fa75b03b)

Summary
In the Linux kernel, the following vulnerability has been resolved:
block/rq_qos: protect rq_qos apis with a new lock
commit 50e34d78815e ("block: disable the elevator int del_gendisk")
move rq_qos_exit() from disk_release() to del_gendisk(), this will
introduce some problems:
1) If rq_qos_add() is triggered by enabling iocost/iolatency through
cgroupfs, then it can concurrent with del_gendisk(), it's not safe to
write 'q->rq_qos' concurrently.
2) Activate cgroup policy that is relied on rq_qos will call
rq_qos_add() and blkcg_activate_policy(), and if rq_qos_exit() is
called in the middle, null-ptr-dereference will be triggered in
blkcg_activate_policy().
3) blkg_conf_open_bdev() can call blkdev_get_no_open() first to find the
disk, then if rq_qos_exit() from del_gendisk() is done before
rq_qos_add(), then memory will be leaked.
This patch add a new disk level mutex 'rq_qos_mutex':
1) The lock will protect rq_qos_exit() directly.
2) For wbt that doesn't relied on blk-cgroup, rq_qos_add() can only be
called from disk initialization for now because wbt can't be
destructed until rq_qos_exit(), so it's safe not to protect wbt for
now. Hoever, in case that rq_qos dynamically destruction is supported
in the furture, this patch also protect rq_qos_add() from wbt_init()
directly, this is enough because blk-sysfs already synchronize
writers with disk removal.
3) For iocost and iolatency, in order to synchronize disk removal and
cgroup configuration, the lock is held after blkdev_get_no_open()
from blkg_conf_open_bdev(), and is released in blkg_conf_exit().
In order to fix the above memory leak, disk_live() is checked after
holding the new lock.

There is no remote or network-facing path into the block rq_qos layer.\nAC:L - The attacker controls both sides: they can loop the `io.latency` write against any device by MAJ:MIN (no permission check in `blkg_conf_open_bdev()`) while triggering repeated disk teardown (loop/nbd device delete), and can stretch the `rq_qos_add()`\u2192`timer_setup()` window arbitrarily by populating the queue with thousands of blkgs so `blkcg_activate_policy()` spends a long time in GFP_KERNEL allocation and retry.\nPR:L - No capability check exists on the path \u2014 `iolatency_set_limit()`/`blkg_conf_open_bdev()` gate only on cgroupfs file permissions, and `cgroup_add_file()` creates interface files owned by `current_fsuid()`, so an unprivileged user with a delegated cgroup v2 subtree (systemd delegation, container runtimes) can write `io.latency` and target any block device on the system.\nUI:N - The attacker performs both the cgroup configuration write and the disk removal themselves; no action by any other user or administrator is needed.\nS:U - The corruption is confined to kernel heap objects and the block layer\u0027s request_queue within the same security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The unsynchronized `q-\u003erq_qos` update leaves freed `rq_qos` objects linked in the chain and dangling `blk_iolatency`/gendisk pointers, giving a use-after-free read primitive over reclaimed slab memory that can be groomed to disclose arbitrary kernel data.\nI:H - `blk_iolatency_init()` continues writing (`timer_setup()`, `INIT_WORK()`) into the object already freed by `blkcg_iolatency_exit()`, and `__rq_qos_throttle()` performs an indirect call through `rqos-\u003eops-\u003ethrottle` read from freed memory \u2014 a heap-spray-controllable arbitrary write and control-flow hijack.\nA:H - The race reliably produces kernel oopses \u2014 a NULL dereference through `iolat-\u003eblkiolat` set to NULL by `iolatency_pd_init()`, plus use-after-free faults on the rq_qos chain during I/O submission and from the leaked object\u0027s timer firing after the disk is released."

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: storage: sddr55: Reject out-of-bound new_pba
Discovered by Atuin - Automated Vulnerability Discovery Engine.
new_pba comes from the status packet returned after each write.
A bogus device could report values beyond the block count derived
from info->capacity, letting the driver walk off the end of
pba_to_lba[] and corrupt heap memory.
Reject PBAs that exceed the computed block count and fail the
transfer so we avoid touching out-of-range mapping entries.

Summary
In the Linux kernel, the following vulnerability has been resolved:
igc: Fix Kernel Panic during ndo_tx_timeout callback
The Xeon validation group has been carrying out some loaded tests
with various HW configurations, and they have seen some transmit
queue time out happening during the test. This will cause the
reset adapter function to be called by igc_tx_timeout().
Similar race conditions may arise when the interface is being brought
down and up in igc_reinit_locked(), an interrupt being generated, and
igc_clean_tx_irq() being called to complete the TX.
When the igc_tx_timeout() function is invoked, this patch will turn
off all TX ring HW queues during igc_down() process. TX ring HW queues
will be activated again during the igc_configure_tx_ring() process
when performing the igc_up() procedure later.
This patch also moved existing igc_disable_tx_ring_hw() to avoid using
forward declaration.

This will cause the\nreset adapter function to be called by igc_tx_timeout().\nSimilar race conditions may arise when the interface is being brought\ndown and up in igc_reinit_locked(), an interrupt being generated, and\nigc_clean_tx_irq() being called to complete the TX.\n\nWhen the igc_tx_timeout() function is invoked, this patch will turn\noff all TX ring HW queues during igc_down() process. TX ring HW queues\nwill be activated again during the igc_configure_tx_ring() process\nwhen performing the igc_up() procedure later.\n\nThis patch also moved existing igc_disable_tx_ring_hw() to avoid using\nforward declaration.\n\nKernel trace:\n[ 7678.747813] ------------[ cut here ]------------\n[ 7678.757914] NETDEV WATCHDOG: enp1s0 (igc): transmit queue 2 timed out\n[ 7678.770117] WARNING: CPU: 0 PID: 13 at net/sched/sch_generic.c:525 dev_watchdog+0x1ae/0x1f0\n[ 7678.784459] Modules linked in: xt_conntrack nft_chain_nat xt_MASQUERADE xt_addrtype nft_compat\nnf_tables nfnetlink br_netfilter bridge stp llc overlay dm_mod emrcha(PO) emriio(PO) rktpm(PO)\ncegbuf_mod(PO) patch_update(PO) se(PO) sgx_tgts(PO) mktme(PO) keylocker(PO) svtdx(PO) svfs_pci_hotplug(PO)\nvtd_mod(PO) davemem(PO) svmabort(PO) svindexio(PO) usbx2(PO) ehci_sched(PO) svheartbeat(PO) ioapic(PO)\nsv8259(PO) svintr(PO) lt(PO) pcierootport(PO) enginefw_mod(PO) ata(PO) smbus(PO) spiflash_cdf(PO) arden(PO)\ndsa_iax(PO) oobmsm_punit(PO) cpm(PO) svkdb(PO) ebg_pch(PO) pch(PO) sviotargets(PO) svbdf(PO) svmem(PO)\nsvbios(PO) dram(PO) svtsc(PO) targets(PO) superio(PO) svkernel(PO) cswitch(PO) mcf(PO) pentiumIII_mod(PO)\nfs_svfs(PO) mdevdefdb(PO) svfs_os_services(O) ixgbe mdio mdio_devres libphy emeraldrapids_svdefs(PO)\nregsupport(O) libnvdimm nls_cp437 snd_hda_codec_realtek snd_hda_codec_generic ledtrig_audio snd_hda_intel\nsnd_intel_dspcfg snd_hda_codec snd_hwdep x86_pkg_temp_thermal snd_hda_core snd_pcm snd_timer isst_if_mbox_pci\n[ 7678.784496] input_leds isst_if_mmio sg snd isst_if_common soundcore wmi button sad9(O) drm fuse backlight\nconfigfs efivarfs ip_tables x_tables vmd sdhci led_class rtl8150 r8152 hid_generic pegasus mmc_block usbhid\nmmc_core hid megaraid_sas ixgb igb i2c_algo_bit ice i40e hpsa scsi_transport_sas e1000e e1000 e100 ax88179_178a\nusbnet xhci_pci sd_mod xhci_hcd t10_pi crc32c_intel crc64_rocksoft igc crc64 crc_t10dif usbcore\ncrct10dif_generic ptp crct10dif_common usb_common pps_core\n[ 7679.200403] RIP: 0010:dev_watchdog+0x1ae/0x1f0\n[ 7679.210201] Code: 28 e9 53 ff ff ff 4c 89 e7 c6 05 06 42 b9 00 01 e8 17 d1 fb ff 44 89 e9 4c\n89 e6 48 c7 c7 40 ad fb 81 48 89 c2 e8 52 62 82 ff \u003c0f\u003e 0b e9 72 ff ff ff 65 8b 05 80 7d 7c 7e\n89 c0 48 0f a3 05 0a c1\n[ 7679.245438] RSP: 0018:ffa00000001f7d90 EFLAGS: 00010282\n[ 7679.256021] RAX: 0000000000000000 RBX: ff11000109938440 RCX: 0000000000000000\n[ 7679.268710] RDX: ff11000361e26cd8 RSI: ff11000361e1b880 RDI: ff11000361e1b880\n[ 7679.281314] RBP: ffa00000001f7da8 R08: ff1100035f8fffe8 R09: 0000000000027ffb\n[ 7679.293840] R10: 0000000000001f0a R11: ff1100035f840000 R12: ff11000109938000\n[ 7679.306276] R13: 0000000000000002 R14: dead000000000122 R15: ffa00000001f7e18\n[ 7679.318648] FS: 0000000000000000(0000) GS:ff11000361e00000(0000) knlGS:0000000000000000\n[ 7679.332064] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[ 7679.342757] CR2: 00007ffff7fca168 CR3: 000000013b08a006 CR4: 0000000000471ef8\n[ 7679.354984] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n[ 7679.367207] DR3: 0000000000000000 DR6: 00000000fffe07f0 DR7: 0000000000000400\n[ 7679.379370] PKRU: 55555554\n[ 7679.386446] Call Trace:\n[ 7679.393152] \u003cTASK\u003e\n[ 7679.399363] ? __pfx_dev_watchdog+0x10/0x10\n[ 7679.407870] call_timer_fn+0x31/0x110\n[ 7679.415698] e\n---truncated---"

"value": "AV:L - The defect lives in the igc driver\u0027s local down/reset and TX-completion paths (`igc_down()` vs `igc_clean_tx_irq()`), reached through local netdev lifecycle operations and locally generated transmit traffic, not by parsing data received from a remote peer. A remote peer can only indirectly induce host TX load, so Local is the correct access vector.\nAC:L - The attacker controls the racing side \u2014 sustained local transmit traffic keeps socket-owned skbs in flight and `igc_clean_tx_irq()` firing \u2014 while the window is enormous rather than narrow: the HW TX queues stay enabled across a 10\u201320 ms sleep, a full `igc_reset()`, the skb free loop, the ring/BQL memset, and the re-arm in `igc_up()`. `igc_tx_timeout()` even writes `IGC_EICS` to force interrupts on every queue, so the colliding NAPI poll is generated by the driver itself; repeated reinit cycles under load hit it reliably.\nPR:L - No capability check exists anywhere on the path from packet transmission \u2192 stalled queue \u2192 `dev_watchdog` \u2192 `igc_tx_timeout()` \u2192 `igc_reset_task()` \u2192 `igc_down()`, so an unprivileged local account generating load drives the whole sequence; the reinit variant needs only namespace-level CAP_NET_ADMIN over a delegated netdev rather than init-namespace root. This matches the scoring of the equivalent mlx5e tx-timeout race (CVE-2024-45019) and ice tx_buf double-free (CVE-2026-53009).\nUI:N - The reset runs from the kernel watchdog timer and `igc_reset_task()` workqueue, and the completion path runs in softirq/NAPI context. No victim action of any kind is required.\nS:U - The corrupted objects (`sk_buff`, `struct sock`, `igc_ring`/`igc_tx_buffer` state, the dql counters) all belong to the host kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The double `napi_consume_skb()` on an already-freed skb plus the `sock` refcount underflow confirmed in the `tcp_wfree` trace is a genuine use-after-free on slab objects the attacker can groom by controlling socket and skb allocation. Such a UAF read primitive can be leveraged to disclose kernel memory.\nI:H - A double-free of an skb and a refcount underflow on `struct sock` corrupt allocator metadata and leave a freed socket still referenced, which is a standard heap-corruption primitive shapeable into an arbitrary write or control-flow hijack. Under conservative scoring this warrants High integrity impact.\nA:H - The commit is literally titled \"Fix Kernel Panic\" and the reported outcome is a `BUG_ON` in `dql_completed()` taken in interrupt context \u2014 \"PANIC: Fatal exception in interrupt\" \u2014 a complete, unrecoverable system crash. The use-after-free independently produces oopses and slab corruption even when not fully exploited."

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: gs_usb: gs_usb_xmit_callback(): fix handling of failed transmitted URBs
The driver lacks the cleanup of failed transfers of URBs. This reduces the
number of available URBs per error by 1. This leads to reduced performance
and ultimately to a complete stop of the transmission.
If the sending of a bulk URB fails do proper cleanup:
- increase netdev stats
- mark the echo_sbk as free
- free the driver's context and do accounting
- wake the send queue

Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: via-sdmmc: fix return value check of mmc_add_host()
mmc_add_host() may return error, if we ignore its return value,
it will lead two issues:
1. The memory that allocated in mmc_alloc_host() is leaked.
2. In the remove() path, mmc_remove_host() will be called to
delete device, but it's not added yet, it will lead a kernel
crash because of null-ptr-deref in device_del().
Fix this by checking the return value and goto error path which
will call mmc_free_host().

Summary
In the Linux kernel, the following vulnerability has been resolved:
usbnet: Prevents free active kevent
The root cause of this issue are:
1. When probing the usbnet device, executing usbnet_link_change(dev, 0, 0);
put the kevent work in global workqueue. However, the kevent has not yet
been scheduled when the usbnet device is unregistered. Therefore, executing
free_netdev() results in the "free active object (kevent)" error reported
here.
2. Another factor is that when calling usbnet_disconnect()->unregister_netdev(),
if the usbnet device is up, ndo_stop() is executed to cancel the kevent.
However, because the device is not up, ndo_stop() is not executed.
The solution to this problem is to cancel the kevent before executing
free_netdev().

Summary
In the Linux kernel, the following vulnerability has been resolved:
vhost-vdpa: fix an iotlb memory leak
Before commit 3d5698793897 ("vhost-vdpa: introduce asid based IOTLB")
we called vhost_vdpa_iotlb_unmap(v, iotlb, 0ULL, 0ULL - 1) during
release to free all the resources allocated when processing user IOTLB
messages through vhost_vdpa_process_iotlb_update().
That commit changed the handling of IOTLB a bit, and we accidentally
removed some code called during the release.
We partially fixed this with commit 037d4305569a ("vhost-vdpa: call
vhost_vdpa_cleanup during the release") but a potential memory leak is
still there as showed by kmemleak if the application does not send
VHOST_IOTLB_INVALIDATE or crashes:
unreferenced object 0xffff888007fbaa30 (size 16):
comm "blkio-bench", pid 914, jiffies 4294993521 (age 885.500s)
hex dump (first 16 bytes):
40 73 41 07 80 88 ff ff 00 00 00 00 00 00 00 00 @sA.............

[<00000000986ec465>] entry_SYSCALL_64_after_hwframe+0x63/0xcd
Let's fix this calling vhost_vdpa_iotlb_unmap() on the whole range in
vhost_vdpa_remove_as(). We move that call before vhost_dev_cleanup()
since we need a valid v->vdev.mm in vhost_vdpa_pa_unmap().
vhost_iotlb_reset() call can be removed, since vhost_vdpa_iotlb_unmap()
on the whole range removes all the entries.
The kmemleak log reported was observed with a vDPA device that has `use_va`
set to true (e.g. VDUSE). This patch has been tested with both types of
devices.

Summary
In the Linux kernel, the following vulnerability has been resolved:
regmap: slimbus: fix bus_context pointer in regmap init calls
Commit 4e65bda8273c ("ASoC: wcd934x: fix error handling in
wcd934x_codec_parse_data()") revealed the problem in the slimbus regmap.
That commit breaks audio playback, for instance, on sdm845 Thundercomm

The __devm_regmap_init_slimbus() started to be used instead of
__regmap_init_slimbus() after the commit mentioned above and turns out
the incorrect bus_context pointer (3rd argument) was used in
__devm_regmap_init_slimbus(). It should be just "slimbus" (which is equal
to &slimbus->dev). Correct it. The wcd934x codec seems to be the only or
the first user of devm_regmap_init_slimbus() but we should fix it till
the point where __devm_regmap_init_slimbus() was introduced therefore
two "Fixes" tags.
While at this, also correct the same argument in __regmap_init_slimbus().

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: early: xhci-dbc: Fix a potential out-of-bound memory access
If xdbc_bulk_write() fails, the values in 'buf' can be anything. So the
string is not guaranteed to be NULL terminated when xdbc_trace() is called.
Reserve an extra byte, which will be zeroed automatically because 'buf' is
a static variable, in order to avoid troubles, should it happen.

Summary
In the Linux kernel, the following vulnerability has been resolved:
power: supply: bq27xxx: Fix poll_interval handling and races on remove
Before this patch bq27xxx_battery_teardown() was setting poll_interval = 0
to avoid bq27xxx_battery_update() requeuing the delayed_work item.
There are 2 problems with this:
1. If the driver is unbound through sysfs, rather then the module being
rmmod-ed, this changes poll_interval unexpectedly
2. This is racy, after it being set poll_interval could be changed
before bq27xxx_battery_update() checks it through
/sys/module/bq27xxx_battery/parameters/poll_interval
Fix this by added a removed attribute to struct bq27xxx_device_info and
using that instead of setting poll_interval to 0.
There also is another poll_interval related race on remove(), writing
/sys/module/bq27xxx_battery/parameters/poll_interval will requeue
the delayed_work item for all devices on the bq27xxx_battery_devices
list and the device being removed was only removed from that list
after cancelling the delayed_work item.
Fix this by moving the removal from the bq27xxx_battery_devices list
to before cancelling the delayed_work item.

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: gadget: Fix use-after-free during usb config switch
In the process of switching USB config from rndis to other config,
if the hardware does not support the ->pullup callback, or the
hardware encounters a low probability fault, both of them may cause
the ->pullup callback to fail, which will then cause a system panic
(use after free).
The gadget drivers sometimes need to be unloaded regardless of the
hardware's behavior.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/fbdev-generic: prohibit potential out-of-bounds access
The fbdev test of IGT may write after EOF, which lead to out-of-bound
access for drm drivers with fbdev-generic. For example, run fbdev test
on a x86+ast2400 platform, with 1680x1050 resolution, will cause the
linux kernel hang with the following call trace:

---[ end trace 0000000000000000 ]---
The is because damage rectangles computed by
drm_fb_helper_memory_range_to_clip() function is not guaranteed to be
bound in the screen's active display area. Possible reasons are:
1) Buffers are allocated in the granularity of page size, for mmap system
call support. The shadow screen buffer consumed by fbdev emulation may
also choosed be page size aligned.
2) The DIV_ROUND_UP() used in drm_fb_helper_memory_range_to_clip()
will introduce off-by-one error.
For example, on a 16KB page size system, in order to store a 1920x1080
XRGB framebuffer, we need allocate 507 pages. Unfortunately, the size
1920*1080*4 can not be divided exactly by 16KB.
1920 * 1080 * 4 = 8294400 bytes
506 * 16 * 1024 = 8290304 bytes
507 * 16 * 1024 = 8306688 bytes
line_length = 1920*4 = 7680 bytes
507 * 16 * 1024 / 7680 = 1081.6
off / line_length = 507 * 16 * 1024 / 7680 = 1081
DIV_ROUND_UP(507 * 16 * 1024, 7680) will yeild 1082
memcpy_toio() typically issue the copy line by line, when copy the last
line, out-of-bound access will be happen. Because:
1082 * line_length = 1082 * 7680 = 8309760, and 8309760 > 8306688
Note that userspace may still write to the invisiable area if a larger
buffer than width x stride is exposed. But it is not a big issue as
long as there still have memory resolve the access if not drafting so
far.
- Also limit the y1 (Daniel)
- keep fix patch it to minimal (Daniel)
- screen_size is page size aligned because of it need mmap (Thomas)
- Adding fixes tag (Thomas)

Summary
In the Linux kernel, the following vulnerability has been resolved:
vhost: Take a reference on the task in struct vhost_task.
vhost_task_create() creates a task and keeps a reference to its
task_struct. That task may exit early via a signal and its task_struct
will be released.
A pending vhost_task_wake() will then attempt to wake the task and
access a task_struct which is no longer there.
Acquire a reference on the task_struct while creating the thread and
release the reference while the struct vhost_task itself is removed.
If the task exits early due to a signal, then the vhost_task_wake() will
still access a valid task_struct. The wake is safe and will be skipped
in this case.

No remote or adjacent-network peer can reach `vhost_task_create()`/`vhost_task_wake()`.\nAC:L - The attacker controls both sides of the race: it creates the vhost worker via VHOST_SET_OWNER/VHOST_NEW_WORKER (which unconditionally calls `vhost_worker_queue()` \u2192 `vhost_task_wake()` with no `killed` check) and delivers the SIGKILL from a sibling process, and can retry the sequence indefinitely at no cost. Per UAF guidance this is Low.\nPR:L - Only an ordinary local account with access to the vhost misc devices or /dev/kvm is needed \u2014 there is not a single `capable()`/CAP_* check on the vhost ioctl path, and `vhost_dev_check_owner()` merely compares `dev-\u003emm == current-\u003emm`. On typical KVM/virtualization hosts these nodes are group- or world-accessible and QEMU itself runs unprivileged.\nUI:N - The attacker performs every step itself \u2014 open the device, issue the ioctl, send the signal, trigger the wake. No action by any other user or administrator is required.\nS:U - The freed `task_struct` and the code corrupting it both live in the host kernel, so the impact stays within the kernel\u0027s own security authority. This is a standard local privilege-escalation surface, not a guest-to-host or IOMMU boundary crossing.\nC:H - A use-after-free on `task_struct` lets the attacker reclaim the slab object with sprayed content and have the scheduler operate on it, which is readily leveraged into kernel memory disclosure and, once escalated, full read access to all system memory.\nI:H - `wake_up_process()` on the freed task reaches `activate_task()` \u2192 `p-\u003esched_class-\u003eenqueue_task()`, an indirect call through a function pointer read from freed memory, and enqueues attacker-reallocated data onto a runqueue \u2014 a control-flow-hijack and arbitrary-write primitive.\nA:H - Even without successful exploitation, dereferencing and locking a freed `task_struct` inside the scheduler reliably produces a kernel oops/panic or runqueue corruption, taking down the entire host including all VMs it serves."

Summary
In the Linux kernel, the following vulnerability has been resolved:
cpufreq: qcom: fix memory leak in error path
If for some reason the speedbin length is incorrect, then there is a
memory leak in the error path because we never free the speedbin buffer.
This commit fixes the error path to always free the speedbin buffer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nsh: Restore skb->{protocol,data,mac_header} for outer header in nsh_gso_segment().
syzbot triggered various splats (see [0] and links) by a crafted GSO
packet of VIRTIO_NET_HDR_GSO_UDP layering the following protocols:
ETH_P_8021AD + ETH_P_NSH + ETH_P_IPV6 + IPPROTO_UDP
NSH can encapsulate IPv4, IPv6, Ethernet, NSH, and MPLS. As the inner
protocol can be Ethernet, NSH GSO handler, nsh_gso_segment(), calls
skb_mac_gso_segment() to invoke inner protocol GSO handlers.
nsh_gso_segment() does the following for the original skb before
calling skb_mac_gso_segment()
1. reset skb->network_header
2. save the original skb->{mac_heaeder,mac_len} in a local variable
3. pull the NSH header
4. resets skb->mac_header
5. set up skb->mac_len and skb->protocol for the inner protocol.
and does the following for the segmented skb
6. set ntohs(ETH_P_NSH) to skb->protocol
7. push the NSH header
8. restore skb->mac_header
9. set skb->mac_header + mac_len to skb->network_header
10. restore skb->mac_len
There are two problems in 6-7 and 8-9.
(a)
After 6 & 7, skb->data points to the NSH header, so the outer header
(ETH_P_8021AD in this case) is stripped when skb is sent out of netdev.
Also, if NSH is encapsulated by NSH + Ethernet (so NSH-Ethernet-NSH),
skb_pull() in the first nsh_gso_segment() will make skb->data point
to the middle of the outer NSH or Ethernet header because the Ethernet
header is not pulled by the second nsh_gso_segment().
(b)
While restoring skb->{mac_header,network_header} in 8 & 9,
nsh_gso_segment() does not assume that the data in the linear
buffer is shifted.
However, udp6_ufo_fragment() could shift the data and change
skb->mac_header accordingly as demonstrated by syzbot.
If this happens, even the restored skb->mac_header points to
the middle of the outer header.
It seems nsh_gso_segment() has never worked with outer headers so far.
At the end of nsh_gso_segment(), the outer header must be restored for
the segmented skb, instead of the NSH header.
To do that, let's calculate the outer header position relatively from
the inner header and set skb->{data,mac_header,protocol} properly.

As the inner\nprotocol can be Ethernet, NSH GSO handler, nsh_gso_segment(), calls\nskb_mac_gso_segment() to invoke inner protocol GSO handlers.\n\nnsh_gso_segment() does the following for the original skb before\ncalling skb_mac_gso_segment()\n\n 1. reset skb-\u003enetwork_header\n 2. save the original skb-\u003e{mac_heaeder,mac_len} in a local variable\n 3. pull the NSH header\n 4. resets skb-\u003emac_header\n 5. set up skb-\u003emac_len and skb-\u003eprotocol for the inner protocol.\n\nand does the following for the segmented skb\n\n 6. set ntohs(ETH_P_NSH) to skb-\u003eprotocol\n 7. push the NSH header\n 8. restore skb-\u003emac_header\n 9. set skb-\u003emac_header + mac_len to skb-\u003enetwork_header\n 10. restore skb-\u003emac_len\n\nThere are two problems in 6-7 and 8-9.\n\n (a)\n After 6 \u0026 7, skb-\u003edata points to the NSH header, so the outer header\n (ETH_P_8021AD in this case) is stripped when skb is sent out of netdev.\n\n Also, if NSH is encapsulated by NSH + Ethernet (so NSH-Ethernet-NSH),\n skb_pull() in the first nsh_gso_segment() will make skb-\u003edata point\n to the middle of the outer NSH or Ethernet header because the Ethernet\n header is not pulled by the second nsh_gso_segment().\n\n (b)\n While restoring skb-\u003e{mac_header,network_header} in 8 \u0026 9,\n nsh_gso_segment() does not assume that the data in the linear\n buffer is shifted.\n\n However, udp6_ufo_fragment() could shift the data and change\n skb-\u003emac_header accordingly as demonstrated by syzbot.\n\n If this happens, even the restored skb-\u003emac_header points to\n the middle of the outer header.\n\nIt seems nsh_gso_segment() has never worked with outer headers so far.\n\nAt the end of nsh_gso_segment(), the outer header must be restored for\nthe segmented skb, instead of the NSH header.\n\nTo do that, let\u0027s calculate the outer header position relatively from\nthe inner header and set skb-\u003e{data,mac_header,protocol} properly.\n\n[0]:\nBUG: KMSAN: uninit-value in ipvlan_process_outbound drivers/net/ipvlan/ipvlan_core.c:524 [inline]\nBUG: KMSAN: uninit-value in ipvlan_xmit_mode_l3 drivers/net/ipvlan/ipvlan_core.c:602 [inline]\nBUG: KMSAN: uninit-value in ipvlan_queue_xmit+0xf44/0x16b0 drivers/net/ipvlan/ipvlan_core.c:668\n ipvlan_process_outbound drivers/net/ipvlan/ipvlan_core.c:524 [inline]\n ipvlan_xmit_mode_l3 drivers/net/ipvlan/ipvlan_core.c:602 [inline]\n ipvlan_queue_xmit+0xf44/0x16b0 drivers/net/ipvlan/ipvlan_core.c:668\n ipvlan_start_xmit+0x5c/0x1a0 drivers/net/ipvlan/ipvlan_main.c:222\n __netdev_start_xmit include/linux/netdevice.h:4989 [inline]\n netdev_start_xmit include/linux/netdevice.h:5003 [inline]\n xmit_one net/core/dev.c:3547 [inline]\n dev_hard_start_xmit+0x244/0xa10 net/core/dev.c:3563\n __dev_queue_xmit+0x33ed/0x51c0 net/core/dev.c:4351\n dev_queue_xmit include/linux/netdevice.h:3171 [inline]\n packet_xmit+0x9c/0x6b0 net/packet/af_packet.c:276\n packet_snd net/packet/af_packet.c:3081 [inline]\n packet_sendmsg+0x8aef/0x9f10 net/packet/af_packet.c:3113\n sock_sendmsg_nosec net/socket.c:730 [inline]\n __sock_sendmsg net/socket.c:745 [inline]\n __sys_sendto+0x735/0xa10 net/socket.c:2191\n __do_sys_sendto net/socket.c:2203 [inline]\n __se_sys_sendto net/socket.c:2199 [inline]\n __x64_sys_sendto+0x125/0x1c0 net/socket.c:2199\n do_syscall_x64 arch/x86/entry/common.c:52 [inline]\n do_syscall_64+0xcf/0x1e0 arch/x86/entry/common.c:83\n entry_SYSCALL_64_after_hwframe+0x63/0x6b\n\nUninit was created at:\n slab_post_alloc_hook mm/slub.c:3819 [inline]\n slab_alloc_node mm/slub.c:3860 [inline]\n __do_kmalloc_node mm/slub.c:3980 [inline]\n __kmalloc_node_track_caller+0x705/0x1000 mm/slub.c:4001\n kmalloc_reserve+0x249/0x4a0 net/core/skbuff.c:582\n __\n---truncated---"

NSH has no GRO/receive-offload handler, so a remote peer cannot cause the kernel to construct an NSH-typed GSO skb with an outer header; the trigger must be locally injected.\nAC:L - The attacker fully controls the packet layering, the outer header length and the GSO parameters, so the broken header restore is hit deterministically on every send \u2014 syzbot produced C reproducers for both reported splats. No race, timing window or uncontrollable memory layout is involved.\nPR:L - Sending the crafted GSO frame requires only a raw packet socket (CAP_NET_RAW), which an unprivileged user obtains inside a user+network namespace via `unshare -Urn`, and the nsh offload handler can be autoloaded unprivileged through the openvswitch generic-netlink family alias (`ctrl_getfamily()` calls `request_module()` with no capability check). No real root or init-namespace privilege is needed.\nUI:N - The attacker triggers the entire sequence himself with a single sendto() on his own socket. No victim action, mount, or file open is required.\nS:U - The corruption is confined to kernel skb metadata and buffers handled by the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - Each segment\u0027s `mac_header`/`network_header` are set to offsets belonging to a different skb, so the kernel reads uninitialized/stale heap headroom and interprets it as the outer Ethernet header (KMSAN uninit-value in `ipvlan_process_outbound` reading `ethh-\u003eh_dest`); those recycled heap bytes steer routing and can be emitted on the wire, and the negative `skb_network_offset()` extends reads outside the packet data rather than confining them to a small bounded field.\nI:H - The skb geometry corruption makes the kernel write protocol header fields (IPv6 `payload_len`, `nexthdr`) at mis-located offsets and transmit frames whose outer 802.1AD/Ethernet header has been stripped or truncated, letting an attacker punch packets out with framing the stack never intended and defeating VLAN-based segmentation; corrupted header offsets fed to NIC offload descriptors extend this to attacker-influenced buffer regions.\nA:H - syzbot reproduced kernel splats on this path (KMSAN uninit-value via `ipvlan_queue_xmit` and a `WARNING in gre_tap_xmit` from `pskb_inet_may_pull()` on a wrapped length), which panic the machine under panic_on_warn, and the unchecked `__skb_push()` plus negative `skb_network_offset()` arithmetic can drive downstream `skb_pull()`/`skb_push()` into `BUG_ON(skb-\u003elen \u003c skb-\u003edata_len)` / `skb_under_panic()`. The attacker can repeat the send in a loop."

Summary
In the Linux kernel, the following vulnerability has been resolved:
maple_tree: fix potential out-of-bounds access in mas_wr_end_piv()
Check the write offset end bounds before using it as the offset into the
pivot array. This avoids a possible out-of-bounds access on the pivot
array if the write extends to the last slot in the node, in which case the
node maximum should be used as the end pivot.
akpm: this doesn't affect any current callers, but new users of mapletree
may encounter this problem if backported into earlier kernels, so let's
fix it in -stable kernels in case of this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: Fix memory leak in rx_desc and tx_desc
Currently when ath12k_dp_cc_desc_init() is called we allocate
memory to rx_descs and tx_descs. In ath12k_dp_cc_cleanup(), during
descriptor cleanup rx_descs and tx_descs memory is not freed.
This is cause of memory leak. These allocated memory should be
freed in ath12k_dp_cc_cleanup.
In ath12k_dp_cc_desc_init(), we can save base address of rx_descs
and tx_descs. In ath12k_dp_cc_cleanup(), we can free rx_descs and
tx_descs memory using their base address.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1

Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: Use __sk_dst_get() and dst_dev_rcu() in get_netdev_for_sock().
get_netdev_for_sock() is called during setsockopt(),
so not under RCU.
Using sk_dst_get(sk)->dev could trigger UAF.
Let's use __sk_dst_get() and dst_dev_rcu().
Note that the only ->ndo_sk_get_lower_dev() user is
bond_sk_get_lower_dev(), which uses RCU.

Summary
In the Linux kernel, the following vulnerability has been resolved:
posix-timers: Prevent RT livelock in itimer_delete()
itimer_delete() has a retry loop when the timer is concurrently expired. On
non-RT kernels this just spin-waits until the timer callback has completed,
except for posix CPU timers which have HAVE_POSIX_CPU_TIMERS_TASK_WORK
enabled.
In that case and on RT kernels the existing task could live lock when
preempting the task which does the timer delivery.
Replace spin_unlock() with an invocation of timer_wait_running() to handle
it the same way as the other retry loops in the posix timer code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/vfio-ap: fix memory leak in vfio_ap device driver
The device release callback function invoked to release the matrix device
uses the dev_get_drvdata(device *dev) function to retrieve the
pointer to the vfio_matrix_dev object in order to free its storage. The
problem is, this object is not stored as drvdata with the device; since the
kfree function will accept a NULL pointer, the memory for the
vfio_matrix_dev object is never freed.
Since the device being released is contained within the vfio_matrix_dev
object, the container_of macro will be used to retrieve its pointer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/radeon: Remove calls to drm_put_dev()
Since the allocation of the drivers main structure was changed to
devm_drm_dev_alloc() drm_put_dev()'ing to trigger it to be free'd
should be done by devres.
However, drm_put_dev() is still in the probe error and device remove
paths. When the driver fails to probe warnings like the following are
shown because devres is trying to drm_put_dev() after the driver
already did it.
[ 5.642230] radeon 0000:01:05.0: probe with driver radeon failed with error -22
[ 5.649605] ------------[ cut here ]------------
[ 5.649607] refcount_t: underflow; use-after-free.
[ 5.649620] WARNING: CPU: 0 PID: 357 at lib/refcount.c:28 refcount_warn_saturate+0xbe/0x110
(cherry picked from commit 3eb8c0b4c091da0a623ade0d3ee7aa4a93df1ea4)

Summary
In the Linux kernel, the following vulnerability has been resolved:
Squashfs: reject negative file sizes in squashfs_read_inode()
Syskaller reports a "WARNING in ovl_copy_up_file" in overlayfs.
This warning is ultimately caused because the underlying Squashfs file
system returns a file with a negative file size.
This commit checks for a negative file size and returns EINVAL.
[phillip@squashfs.org.uk: only need to check 64 bit quantity]

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: musb: Fix musb_gadget.c rxstate overflow bug
The usb function device call musb_gadget_queue() adds the passed
request to musb_ep::req_list,If the (request->length > musb_ep->packet_sz)
and (is_buffer_mapped(req) return false),the rxstate() will copy all data
in fifo to request->buf which may cause request->buf out of bounds.
Fix it by add the length check :
fifocnt = min_t(unsigned, request->length - request->actual, fifocnt);

Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix missed ses refcounting
Use new cifs_smb_ses_inc_refcount() helper to get an active reference
of @ses and @ses->dfs_root_ses (if set). This will prevent
@ses->dfs_root_ses of being put in the next call to cifs_put_smb_ses()
and thus potentially causing an use-after-free bug.

A malicious, compromised, or MITM\u0027d SMB/DFS server drives the refcount underflow purely over the network.\nAC:L - The imbalance is deterministic, not a race: every `smb2_find_smb_ses_unlocked()` acquisition drops one extra reference on `ses-\u003edfs_root_ses` at release, so the attacker simply drives enough signed exchanges to force the count to zero. No memory-layout or timing condition outside the attacker\u0027s control is needed.\nPR:N - The attacker is the remote SMB/DFS server (or a network MITM) and holds no privileges or account on the victim client; referral responses and dialect negotiation happen without any credential on the target system.\nUI:N - The `smb2transport.c` half of the bug is a steady-state runtime path \u2014 on an already-mounted DFS share, signature calculation, cancelled-MID handling, echo keepalives and the DFS cache refresh worker accumulate the extra puts with no user action at attack time.\nS:U - The premature free and subsequent corruption are confined to kernel memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Use-after-free on a `cifs_ses` object whose slot can be reoccupied by attacker-groomed heap data yields a read primitive, and the freed session still holds authentication material (`auth_key.response`, signing keys) and kernel pointers used by subsequent code.\nI:H - After the free, `cifs_put_smb_ses()` reads `ses-\u003eserver` from freed memory and performs an indirect call via `server-\u003eops-\u003elogoff()`, giving a control-flow hijack primitive; heap spraying over the freed `cifs_ses` converts this into arbitrary write/code execution.\nA:H - The refcount underflow frees a session still referenced by child sessions, tcons, and the DFS cache worker, reliably producing an oops/panic (and a `WARN_ON(ses-\u003eses_count \u003c 0)`) that takes down the machine."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: turn quotas off if mount failed after enabling quotas
Yi found during a review of the patch "ext4: don't BUG on inconsistent
journal feature" that when ext4_mark_recovery_complete() returns an error
value, the error handling path does not turn off the enabled quotas,
which triggers the following kmemleak:

================================================================
To solve this problem, we add a "failed_mount10" tag, and call
ext4_quota_off_umount() in this tag to release the enabled qoutas.

Summary
In the Linux kernel, the following vulnerability has been resolved:
udmabuf: Set ubuf->sg = NULL if the creation of sg table fails
When userspace tries to map the dmabuf and if for some reason
(e.g. OOM) the creation of the sg table fails, ubuf->sg needs to be
set to NULL. Otherwise, when the userspace subsequently closes the
dmabuf fd, we'd try to erroneously free the invalid sg table from
release_udmabuf resulting in the following crash reported by syzbot:
general protection fault, probably for non-canonical address
0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASAN

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix "kernel NULL pointer dereference" error
When rxe_queue_init in the function rxe_qp_init_req fails,
both qp->req.task.func and qp->req.task.arg are not initialized.
Because of creation of qp fails, the function rxe_create_qp will
call rxe_qp_do_cleanup to handle allocated resource.
Before calling __rxe_do_task, both qp->req.task.func and
qp->req.task.arg should be checked.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/bnxt_re: Prevent handling any completions after qp destroy
HW may generate completions that indicates QP is destroyed.
Driver should not be scheduling any more completion handlers
for this QP, after the QP is destroyed. Since CQs are active
during the QP destroy, driver may still schedule completion
handlers. This can cause a race where the destroy_cq and poll_cq
running simultaneously.
Snippet of kernel panic while doing bnxt_re driver load unload in loop.
This indicates a poll after the CQ is freed.
[77786.481636] Call Trace:

To avoid this, complete all completion handlers before returning the
destroy QP. If free_cq is called soon after destroy_qp, IB stack
will cancel the CQ work before invoking the destroy_cq verb and
this will prevent any race mentioned.

Summary
In the Linux kernel, the following vulnerability has been resolved:
orangefs: fix xattr related buffer overflow...
Willy Tarreau <w@1wt.eu> forwarded me a message from
Disclosure <disclosure@aisle.com> with the following
warning:
> The helper `xattr_key()` uses the pointer variable in the loop condition
> rather than dereferencing it. As `key` is incremented, it remains non-NULL
> (until it runs into unmapped memory), so the loop does not terminate on
> valid C strings and will walk memory indefinitely, consuming CPU or hanging
> the thread.
I easily reproduced this with setfattr and getfattr, causing a kernel
oops, hung user processes and corrupted orangefs files. Disclosure
sent along a diff (not a patch) with a suggested fix, which I based
this patch on.
After xattr_key started working right, xfstest generic/069 exposed an
xattr related memory leak that lead to OOM. xattr_key returns
a hashed key. When adding xattrs to the orangefs xattr cache, orangefs
used hash_add, a kernel hashing macro. hash_add also hashes the key using
hash_log which resulted in additions to the xattr cache going to the wrong
hash bucket. generic/069 tortures a single file and orangefs does a
getattr for the xattr "security.capability" every time. Orangefs
negative caches on xattrs which includes a kmalloc. Since adds to the
xattr cache were going to the wrong bucket, every getattr for
"security.capability" resulted in another kmalloc, none of which were
ever freed.
I changed the two uses of hash_add to hlist_add_head instead
and the memory leak ceased and generic/069 quit throwing furniture.

The ACL/`security.capability` paths fire during ordinary permission checks and execve, needing no explicit privilege at all.\nUI:N - The attacker triggers the bug entirely through their own syscalls with no victim action required. An existing OrangeFS mount is a property of the deployment, not an action the attacker must induce a user to perform.\nS:U - The out-of-bounds read, hang, and oops all occur within the kernel of the same host, with no crossing into another security authority such as a hypervisor or IOMMU boundary.\nC:H - This is an unbounded out-of-bounds read that walks arbitrary kernel memory \u2014 live kernel stack contents, .rodata/.data, or the slab and direct map \u2014 far beyond a few bounded bytes. The resulting hash bucket (`sum % 16`) is observable to the attacker as a cache-hit/miss timing oracle over that adjacent kernel memory.\nI:H - The maintainer directly observed \"corrupted orangefs files\" when reproducing the bug, a confirmed loss of integrity of user data on a shared parallel filesystem. The broken xattr cache additionally governs POSIX ACL and `security.capability` retrieval, so mis-bucketed and stale entries can corrupt access-control and file-capability decisions.\nA:H - Confirmed kernel oops, hung user processes, and OOM from the associated unbounded kmalloc leak. The loop has no `cond_resched()` and runs with `xattr_sem` write-held in the set/remove paths, so it burns a CPU until it faults while blocking every other thread on that inode \u2014 soft lockups, RCU stalls, and hung tasks."

Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix potential cfid UAF in smb2_query_info_compound
When smb2_query_info_compound() retries, a previously allocated cfid may
have been freed in the first attempt.
Because cfid wasn't reset on replay, later cleanup could act on a stale
pointer, leading to a potential use-after-free.
Reinitialize cfid to NULL under the replay label.
Example trace (trimmed):
refcount_t: underflow; use-after-free.

"value": "AV:N - Both halves of the bug are driven entirely by a remote SMB peer \u2014 the server decides when `compound_send_recv()` returns the replayable error (`-EAGAIN`/`-ECONNABORTED`) that reaches `replay_again:`, and it sends the SMB2 lease-break that makes `cached_dir_lease_break()` drop the cfid\u0027s last reference and free it. A malicious/compromised file server or an on-path attacker against an SMB session without signing can reach this over the network or WAN.\nAC:L - The server has deterministic control of every precondition: it triggers the replayable error, times the lease break that frees the cfid, and fails its second CREATE so `open_cached_dir()` returns without resetting `*ret_cfid`, leaving the dangling pointer guaranteed. No memory layout or timing condition outside the attacker\u0027s control is required, and the replay backoff plus a full round trip give a generous heap-grooming window.\nPR:N - The attacker is the remote SMB server or an on-path attacker and holds no privileges or credentials on the victim system. The client-side entry points (`statfs`, `getxattr`, `listxattr`) need only an unprivileged user and in practice fire unprompted from `df`, monitoring agents and container runtimes.\nUI:N - The CIFS mount is a standing deployment condition (fstab/autofs/automount in enterprise and NAS setups), not a per-attempt victim action; once it exists the server drives the entire sequence itself. It only needs to wait for a routine `statfs()`/xattr operation, which recurs continuously without any user acting.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority as the vulnerable cifs client code. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - On replay the stale `cfid-\u003efid.persistent_fid` and `volatile_fid` are read from freed slab memory and transmitted verbatim to the attacker\u0027s server in the SMB2 QUERY_INFO request, a repeatable kernel-heap infoleak usable to defeat KASLR. Controlling the reallocated object escalates this to arbitrary kernel memory disclosure.\nI:H - Reaching `close_cached_dir()` on the dangling pointer runs `list_del(\u0026cfid-\u003eentry)` with attacker-supplied `next`/`prev` (classic unlink arbitrary write), `cfid-\u003ecfids-\u003enum_entries--`, `dput()` on a forged dentry, and `kfree(cfid-\u003epath)` plus an arbitrary-free loop over the dirents list. Together these yield arbitrary write and arbitrary free, sufficient for control-flow hijack and privilege escalation.\nA:H - The reported trace shows `refcount_t: underflow; use-after-free` with a WARNING in `refcount_warn_saturate()` reached from `smb2_query_info_compound()` via `statfs`. Operating on the freed object readily oopses or panics the kernel, and the server can retrigger it at will."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: stmmac: Correctly handle Rx checksum offload errors
The stmmac_rx function would previously set skb->ip_summed to
CHECKSUM_UNNECESSARY if hardware checksum offload (CoE) was enabled
and the packet was of a known IP ethertype.
However, this logic failed to check if the hardware had actually
reported a checksum error. The hardware status, indicating a header or
payload checksum failure, was being ignored at this stage. This could
cause corrupt packets to be passed up the network stack as valid.
This patch corrects the logic by checking the `csum_none` status flag,
which is set when the hardware reports a checksum error. If this flag
is set, skb->ip_summed is now correctly set to CHECKSUM_NONE,
ensuring the kernel's network stack will perform its own validation and
properly handle the corrupt packet.

An unauthenticated remote sender needs no credentials or account on the target.\nUI:N - Packet reception and NAPI processing happen automatically; no action by any local user or administrator is required for the corrupt packet to be accepted and delivered up the stack.\nS:U - The mis-marked skb is consumed by the same host\u0027s network stack and its applications; no VM, IOMMU, or sandbox boundary is crossed, so the vulnerable and impacted components share one security authority.\nC:N - The flaw only mislabels a checksum result \u2014 there is no out-of-bounds read, no uninitialized memory exposure, and no kernel data is disclosed to the attacker. Packet lengths still come from independently validated IP header fields.\nI:H - The kernel affirmatively asserts \"checksum verified\" for packets the hardware reported as corrupt, so the transport-layer integrity protection for all received IP traffic on the interface is completely lost and corrupt or attacker-mangled payloads reach applications as authentic. It also lets an attacker inject TCP segments that checksum-validating IDS/IPS and passive monitors discard but the host accepts, a security-control bypass and stream-desynchronization attack.\nA:L - Accepted corrupt segments \u2014 flipped control flags, mangled payloads \u2014 cause spurious connection teardowns and application-level protocol failures, degrading service reliability. There is no kernel crash, hang, or deadlock in this path, so the availability loss is partial rather than total."

Summary
In the Linux kernel, the following vulnerability has been resolved:
xfrm: interface: fix use-after-free after changing collect_md xfrm interface
collect_md property on xfrm interfaces can only be set on device creation,
thus xfrmi_changelink() should fail when called on such interfaces.
The check to enforce this was done only in the case where the xi was
returned from xfrmi_locate() which doesn't look for the collect_md
interface, and thus the validation was never reached.
Calling changelink would thus errornously place the special interface xi
in the xfrmi_net->xfrmi hash, but since it also exists in the
xfrmi_net->collect_md_xfrmi pointer it would lead to a double free when
the net namespace was taken down [1].
Change the check to use the xi from netdev_priv which is available earlier
in the function to prevent changes in xfrm collect_md interfaces.
[1] resulting oops:

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd: Fix an out of bounds error in BIOS parser
The array is hardcoded to 8 in atomfirmware.h, but firmware provides
a bigger one sometimes. Deferencing the larger array causes an out
of bounds error.
commit 4fc1ba4aa589 ("drm/amd/display: fix array index out of bound error
in bios parser") fixed some of this, but there are two other cases
not covered by it. Fix those as well.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: clear extent cache after moving/defragmenting extents
The extent map cache can become stale when extents are moved or
defragmented, causing subsequent operations to see outdated extent flags.
This triggers a BUG_ON in ocfs2_refcount_cal_cow_clusters().
The problem occurs when:
1. copy_file_range() creates a reflinked extent with OCFS2_EXT_REFCOUNTED
2. ioctl(FITRIM) triggers ocfs2_move_extents()
3. __ocfs2_move_extents_range() reads and caches the extent (flags=0x2)
4. ocfs2_move_extent()/ocfs2_defrag_extent() calls __ocfs2_move_extent()
which clears OCFS2_EXT_REFCOUNTED flag on disk (flags=0x0)
5. The extent map cache is not invalidated after the move
6. Later write() operations read stale cached flags (0x2) but disk has
updated flags (0x0), causing a mismatch
7. BUG_ON(!(rec->e_flags & OCFS2_EXT_REFCOUNTED)) triggers
Fix by clearing the extent map cache after each extent move/defrag
operation in __ocfs2_move_extents_range(). This ensures subsequent
operations read fresh extent data from disk.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: set goal start correctly in ext4_mb_normalize_request
We need to set ac_g_ex to notify the goal start used in
ext4_mb_find_by_goal. Set ac_g_ex instead of ac_f_ex in
ext4_mb_normalize_request.
Besides we should assure goal start is in range [first_data_block,
blocks_count) as ext4_mb_initialize_context does.
[ Added a check to make sure size is less than ar->pright; otherwise
we could end up passing an underflowed value of ar->pright - size to
ext4_get_group_no_and_offset(), which will trigger a BUG_ON later on.

Summary
In the Linux kernel, the following vulnerability has been resolved:
refscale: Fix uninitalized use of wait_queue_head_t
Running the refscale test occasionally crashes the kernel with the
following error:
[ 8569.952896] BUG: unable to handle page fault for address: ffffffffffffffe8
[ 8569.952900] #PF: supervisor read access in kernel mode
[ 8569.952902] #PF: error_code(0x0000) - not-present page

[ 8569.952916] Hardware name: Dell Inc. PowerEdge R750/0WMWCR, BIOS 1.2.4 05/28/2021
[ 8569.952917] RIP: 0010:prepare_to_wait_event+0x101/0x190
:
[ 8569.952940] Call Trace:
[ 8569.952941] <TASK>

[ 8569.952966] ret_from_fork+0x1f/0x30
[ 8569.952973] </TASK>
The likely cause is that init_waitqueue_head() is called after the call to
the torture_create_kthread() function that creates the ref_scale_reader
kthread. Although this init_waitqueue_head() call will very likely
complete before this kthread is created and starts running, it is
possible that the calling kthread will be delayed between the calls to
torture_create_kthread() and init_waitqueue_head(). In this case, the
new kthread will use the waitqueue head before it is properly initialized,
which is not good for the kernel's health and well-being.
The above crash happened here:
static inline void __add_wait_queue(...)
{
:
if (!(wq->flags & WQ_FLAG_PRIORITY)) <=== Crash here
The offset of flags from list_head entry in wait_queue_entry is
-0x18. If reader_tasks[i].wq.head.next is NULL as allocated reader_task
structure is zero initialized, the instruction will try to access address
0xffffffffffffffe8, which is exactly the fault address listed above.
This commit therefore invokes init_waitqueue_head() before creating
the kthread.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtl818x: rtl8187: Fix potential buffer underflow in rtl8187_rx_cb()
The rtl8187_rx_cb() calculates the rx descriptor header address
by subtracting its size from the skb tail pointer.
However, it does not validate if the received packet
(skb->len from urb->actual_length) is large enough to contain this
header.
If a truncated packet is received, this will lead to a buffer
underflow, reading memory before the start of the skb data area,
and causing a kernel panic.
Add length checks for both rtl8187 and rtl8187b descriptor headers
before attempting to access them, dropping the packet cleanly if the
check fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: 8250: Fix oops for port->pm on uart_change_pm()
Unloading a hardware specific 8250 driver can produce error "Unable to
handle kernel paging request at virtual address" about ten seconds after
unloading the driver. This happens on uart_hangup() calling
uart_change_pm().
Turns out commit 04e82793f068 ("serial: 8250: Reinit port->pm on port
specific driver unbind") was only a partial fix. If the hardware specific
driver has initialized port->pm function, we need to clear port->pm too.
Just reinitializing port->ops does not do this. Otherwise serial8250_pm()
will call port->pm() instead of serial8250_do_pm().

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btusb: mediatek: Avoid btusb_mtk_claim_iso_intf() NULL deref
In btusb_mtk_setup(), we set `btmtk_data->isopkt_intf` to:
usb_ifnum_to_if(data->udev, MTK_ISO_IFNUM)
That function can return NULL in some cases. Even when it returns
NULL, though, we still go on to call btusb_mtk_claim_iso_intf().
As of commit e9087e828827 ("Bluetooth: btusb: mediatek: Add locks for
usb_driver_claim_interface()"), calling btusb_mtk_claim_iso_intf()
when `btmtk_data->isopkt_intf` is NULL will cause a crash because
we'll end up passing a bad pointer to device_lock(). Prior to that
commit we'd pass the NULL pointer directly to
usb_driver_claim_interface() which would detect it and return an
error, which was handled.
Resolve the crash in btusb_mtk_claim_iso_intf() by adding a NULL check
at the start of the function. This makes the code handle a NULL
`btmtk_data->isopkt_intf` the same way it did before the problematic
commit (just with a slight change to the error message printed).

It complains about acquiring a local_lock while holding a raw_spin_lock.
It means it should not allocate memory while holding a raw_spin_lock
since it is not safe for RT.
raw_spin_lock is needed because bpf_local_storage supports tracing
context. In particular for task local storage, it is easy to
get a "current" task PTR_TO_BTF_ID in tracing bpf prog.
However, task (and cgroup) local storage has already been moved to
bpf mem allocator which can be used after raw_spin_lock.
The splat is for the sk storage. For sk (and inode) storage,
it has not been moved to bpf mem allocator. Using raw_spin_lock or not,
kzalloc(GFP_ATOMIC) could theoretically be unsafe in tracing context.
However, the local storage helper requires a verifier accepted
sk pointer (PTR_TO_BTF_ID), it is hypothetical if that (mean running
a bpf prog in a kzalloc unsafe context and also able to hold a verifier
accepted sk pointer) could happen.
This patch avoids kzalloc after raw_spin_lock to silent the splat.
There is an existing kzalloc before the raw_spin_lock. At that point,
a kzalloc is very likely required because a lookup has just been done
before. Thus, this patch always does the kzalloc before acq

Summary
In the Linux kernel, the following vulnerability has been resolved:
inotify: Avoid reporting event with invalid wd
When inotify_freeing_mark() races with inotify_handle_inode_event() it
can happen that inotify_handle_inode_event() sees that i_mark->wd got
already reset to -1 and reports this value to userspace which can
confuse the inotify listener. Avoid the problem by validating that wd is
sensible (and pretend the mark got removed before the event got
generated otherwise).

Summary
In the Linux kernel, the following vulnerability has been resolved:
i2c: xiic: xiic_xfer(): Fix runtime PM leak on error path
The xiic_xfer() function gets a runtime PM reference when the function is
entered. This reference is released when the function is exited. There is
currently one error path where the function exits directly, which leads to
a leak of the runtime PM reference.
Make sure that this error path also releases the runtime PM reference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
exfat: validate cluster allocation bits of the allocation bitmap
syzbot created an exfat image with cluster bits not set for the allocation
bitmap. exfat-fs reads and uses the allocation bitmap without checking
this. The problem is that if the start cluster of the allocation bitmap
is 6, cluster 6 can be allocated when creating a directory with mkdir.
exfat zeros out this cluster in exfat_mkdir, which can delete existing
entries. This can reallocate the allocated entries. In addition,
the allocation bitmap is also zeroed out, so cluster 6 can be reallocated.
This patch adds exfat_test_bitmap_range to validate that clusters used for
the allocation bitmap are correctly marked as in-use.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipmi:ssif: Fix a memory leak when scanning for an adapter
The adapter scan ssif_info_find() sets info->adapter_name if the adapter
info came from SMBIOS, as it's not set in that case. However, this
function can be called more than once, and it will leak the adapter name
if it had already been set. So check for NULL before setting it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rcuscale: Move rcu_scale_writer() schedule_timeout_uninterruptible() to _idle()
The rcuscale.holdoff module parameter can be used to delay the start
of rcu_scale_writer() kthread. However, the hung-task timeout will
trigger when the timeout specified by rcuscale.holdoff is greater than
hung_task_timeout_secs:
runqemu kvm nographic slirp qemuparams="-smp 4 -m 2048M"
bootparams="rcuscale.shutdown=0 rcuscale.holdoff=300"

This commit therefore replaces schedule_timeout_uninterruptible() with
schedule_timeout_idle().

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Prevent decl_tag from being referenced in func_proto arg
Syzkaller managed to hit another decl_tag issue:
btf_func_proto_check kernel/bpf/btf.c:4506 [inline]
btf_check_all_types kernel/bpf/btf.c:4734 [inline]

This seems similar to commit ea68376c8bed ("bpf: prevent decl_tag from being
referenced in func_proto") but for the argument.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915: Avoid lock inversion when pinning to GGTT on CHV/BXT+VTD
On completion of i915_vma_pin_ww(), a synchronous variant of
dma_fence_work_commit() is called. When pinning a VMA to GGTT address
space on a Cherry View family processor, or on a Broxton generation SoC
with VTD enabled, i.e., when stop_machine() is then called from
intel_ggtt_bind_vma(), that can potentially lead to lock inversion among
reservation_ww and cpu_hotplug locks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Enforce expected_attach_type for tailcall compatibility
Yinhao et al. recently reported:
Our fuzzer tool discovered an uninitialized pointer issue in the
bpf_prog_test_run_xdp() function within the Linux kernel's BPF subsystem.
This leads to a NULL pointer dereference when a BPF program attempts to
deference the txq member of struct xdp_buff object.
The test initializes two programs of BPF_PROG_TYPE_XDP: progA acts as the
entry point for bpf_prog_test_run_xdp() and its expected_attach_type can
neither be of be BPF_XDP_DEVMAP nor BPF_XDP_CPUMAP. progA calls into a slot
of a tailcall map it owns. progB's expected_attach_type must be BPF_XDP_DEVMAP
to pass xdp_is_valid_access() validation. The program returns struct xdp_md's
egress_ifindex, and the latter is only allowed to be accessed under mentioned
expected_attach_type. progB is then inserted into the tailcall which progA
calls.
The underlying issue goes beyond XDP though. Another example are programs
of type BPF_PROG_TYPE_CGROUP_SOCK_ADDR. sock_addr_is_valid_access() as well
as sock_addr_func_proto() have different logic depending on the programs'
expected_attach_type. Similarly, a program attached to BPF_CGROUP_INET4_GETPEERNAME
should not be allowed doing a tailcall into a program which calls bpf_bind()
out of BPF which is only enabled for BPF_CGROUP_INET4_CONNECT.
In short, specifying expected_attach_type allows to open up additional
functionality or restrictions beyond what the basic bpf_prog_type enables.
The use of tailcalls must not violate these constraints. Fix it by enforcing
expected_attach_type in __bpf_prog_map_compatible().
Note that we only enforce this for tailcall maps, but not for BPF devmaps or
cpumaps: There, the programs are invoked through dev_map_bpf_prog_run*() and
cpu_map_bpf_prog_run*() which set up a new environment / context and therefore
these situations are not prone to this issue.

The program returns struct xdp_md\u0027s\negress_ifindex, and the latter is only allowed to be accessed under mentioned\nexpected_attach_type. progB is then inserted into the tailcall which progA\ncalls.\n\nThe underlying issue goes beyond XDP though. Another example are programs\nof type BPF_PROG_TYPE_CGROUP_SOCK_ADDR. sock_addr_is_valid_access() as well\nas sock_addr_func_proto() have different logic depending on the programs\u0027\nexpected_attach_type. Similarly, a program attached to BPF_CGROUP_INET4_GETPEERNAME\nshould not be allowed doing a tailcall into a program which calls bpf_bind()\nout of BPF which is only enabled for BPF_CGROUP_INET4_CONNECT.\n\nIn short, specifying expected_attach_type allows to open up additional\nfunctionality or restrictions beyond what the basic bpf_prog_type enables.\nThe use of tailcalls must not violate these constraints. Fix it by enforcing\nexpected_attach_type in __bpf_prog_map_compatible().\n\nNote that we only enforce this for tailcall maps, but not for BPF devmaps or\ncpumaps: There, the programs are invoked through dev_map_bpf_prog_run*() and\ncpu_map_bpf_prog_run*() which set up a new environment / context and therefore\nthese situations are not prone to this issue."

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm: fix NULL pointer dereference in __dm_suspend()
There is a race condition between dm device suspend and table load that
can lead to null pointer dereference. The issue occurs when suspend is
invoked before table load completes:
BUG: kernel NULL pointer dereference, address: 0000000000000054
Oops: 0000 [#1] PREEMPT SMP PTI
CPU: 6 PID: 6798 Comm: dmsetup Not tainted 6.6.0-g7e52f5f0ca9b #62
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.1-2.fc37 04/01/2014
RIP: 0010:blk_mq_wait_quiesce_done+0x0/0x50
Call Trace:

The issue can be triggered as below:
T1 T2
dm_suspend table_load
__dm_suspend dm_setup_md_queue
dm_mq_init_request_queue
blk_mq_init_allocated_queue
=> q->mq_ops = set->ops; (1)
dm_stop_queue / dm_wait_for_completion
=> q->tag_set NULL pointer! (2)
=> q->tag_set = set; (3)
Fix this by checking if a valid table (map) exists before performing
request-based suspend and waiting for target I/O. When map is NULL,
skip these table-dependent suspend steps.
Even when map is NULL, no I/O can reach any target because there is
no table loaded; I/O submitted in this state will fail early in the
DM layer. Skipping the table-dependent suspend logic in this case
is safe and avoids NULL pointer dereferences.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ata: pata_via: Force PIO for ATAPI devices on VT6415/VT6330
The controller has a hardware bug that can hard hang the system when
doing ATAPI DMAs without any trace of what happened. Depending on the
device attached, it can also prevent the system from booting.
In this case, the system hangs when reading the ATIP from optical media
with cdrecord -vvv -atip on an _NEC DVD_RW ND-4571A 1-01 and an
Optiarc DVD RW AD-7200A 1.06 attached to an ASRock 990FX Extreme 4,
running at UDMA/33.
The issue can be reproduced by running the same command with a cygwin
build of cdrecord on WinXP, although it requires more attempts to cause
it. The hang in that case is also resolved by forcing PIO. It doesn't
appear that VIA has produced any drivers for that OS, thus no known
workaround exists.
HDDs attached to the controller do not suffer from any DMA issues.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: deal with integer overflows in kmalloc_reserve()
Blamed commit changed:
ptr = kmalloc(size);
if (ptr)
size = ksize(ptr);
size = kmalloc_size_roundup(size);
ptr = kmalloc(size);
This allowed various crash as reported by syzbot [1]
and Kyle Zeng.
Problem is that if @size is bigger than 0x80000001,
kmalloc_size_roundup(size) returns 2^32.
kmalloc_reserve() uses a 32bit variable (obj_size),
so 2^32 is truncated to 0.
kmalloc(0) returns ZERO_SIZE_PTR which is not handled by
skb allocations.
Following trace can be triggered if a netdev->mtu is set
close to 0x7fffffff
We might in the future limit netdev->mtu to more sensible
limit (like KMALLOC_MAX_SIZE).
This patch is based on a syzbot report, and also a report
and tentative fix from Kyle Zeng.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xfrm: also call xfrm_state_delete_tunnel at destroy time for states that were never added
In commit b441cf3f8c4b ("xfrm: delete x->tunnel as we delete x"), I
missed the case where state creation fails between full
initialization (->init_state has been called) and being inserted on
the lists.
In this situation, ->init_state has been called, so for IPcomp
tunnels, the fallback tunnel has been created and added onto the
lists, but the user state never gets added, because we fail before
that. The user state doesn't go through __xfrm_state_delete, so we
don't call xfrm_state_delete_tunnel for those states, and we end up
leaking the FB tunnel.
There are several codepaths affected by this: the add/update paths, in
both net/key and xfrm, and the migrate code (xfrm_migrate,
xfrm_state_migrate). A "proper" rollback of the init_state work would
probably be doable in the add/update code, but for migrate it gets
more complicated as multiple states may be involved.
At some point, the new (not-inserted) state will be destroyed, so call
xfrm_state_delete_tunnel during xfrm_state_gc_destroy. Most states
will have their fallback tunnel cleaned up during __xfrm_state_delete,
which solves the issue that b441cf3f8c4b (and other patches before it)
aimed at. All states (including FB tunnels) will be removed from the
lists once xfrm_state_fini has called flush_work(&xfrm_state_gc_work).

Summary
In the Linux kernel, the following vulnerability has been resolved:
xfrm: delete x->tunnel as we delete x
The ipcomp fallback tunnels currently get deleted (from the various
lists and hashtables) as the last user state that needed that fallback
is destroyed (not deleted). If a reference to that user state still
exists, the fallback state will remain on the hashtables/lists,
triggering the WARN in xfrm_state_fini. Because of those remaining
references, the fix in commit f75a2804da39 ("xfrm: destroy xfrm_state
synchronously on net exit path") is not complete.
We recently fixed one such situation in TCP due to defered freeing of
skbs (commit 9b6412e6979f ("tcp: drop secpath at the same time as we
currently drop dst")). This can also happen due to IP reassembly: skbs
with a secpath remain on the reassembly queue until netns
destruction. If we can't guarantee that the queues are flushed by the
time xfrm_state_fini runs, there may still be references to a (user)
xfrm_state, preventing the timely deletion of the corresponding
fallback state.
Instead of chasing each instance of skbs holding a secpath one by one,
this patch fixes the issue directly within xfrm, by deleting the
fallback state as soon as the last user state depending on it has been
deleted. Destruction will still happen when the final reference is
dropped.
A separate lockdep class for the fallback state is required since
we're going to lock x->tunnel while x is locked.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm: fix a race condition in retrieve_deps
There's a race condition in the multipath target when retrieve_deps
races with multipath_message calling dm_get_device and dm_put_device.
retrieve_deps walks the list of open devices without holding any lock
but multipath may add or remove devices to the list while it is
running. The end result may be memory corruption or use-after-free
memory access.
See this description of a UAF with multipath_message():
https://listman.redhat.com/archives/dm-devel/2022-October/052373.html
Fix this bug by introducing a new rw semaphore "devices_lock". We grab
devices_lock for read in retrieve_deps and we grab it for write in
dm_get_device and dm_put_device.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sched: fix ordering of qlen adjustment
Changes to sch->q.qlen around qdisc_tree_reduce_backlog() need to happen
_before_ a call to said function because otherwise it may fail to notify
parent qdiscs when the child is about to become empty.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: Fix pci_device_is_present() for VFs by checking PF
pci_device_is_present() previously didn't work for VFs because it reads the
Vendor and Device ID, which are 0xffff for VFs, which looks like they
aren't present. Check the PF instead.
Wei Gong reported that if virtio I/O is in progress when the driver is
unbound or "0" is written to /sys/.../sriov_numvfs, the virtio I/O
operation hangs, which may result in output like this:
task:bash state:D stack: 0 pid: 1773 ppid: 1241 flags:0x00004002
Call Trace:
schedule+0x4f/0xc0
blk_mq_freeze_queue_wait+0x69/0xa0
blk_mq_freeze_queue+0x1b/0x20
blk_cleanup_queue+0x3d/0xd0
virtblk_remove+0x3c/0xb0 [virtio_blk]
virtio_dev_remove+0x4b/0x80
...
device_unregister+0x1b/0x60
unregister_virtio_device+0x18/0x30
virtio_pci_remove+0x41/0x80
pci_device_remove+0x3e/0xb0
This happened because pci_device_is_present(VF) returned "false" in
virtio_pci_remove(), so it called virtio_break_device(). The broken vq
meant that vring_interrupt() skipped the vq.callback() that would have
completed the virtio I/O operation via virtblk_done().
[bhelgaas: commit log, simplify to always use pci_physfn(), add stable tag]

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: set tx_tstamps when creating new Tx rings via ethtool
When the user changes the number of queues via ethtool, the driver
allocates new rings. This allocation did not initialize tx_tstamps. This
results in the tx_tstamps field being zero (due to kcalloc allocation), and
would result in a NULL pointer dereference when attempting a transmit
timestamp on the new ring.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix WARNING in mark_buffer_dirty due to discarded buffer reuse
A syzbot stress test using a corrupted disk image reported that
mark_buffer_dirty() called from __nilfs_mark_inode_dirty() or
nilfs_palloc_commit_alloc_entry() may output a kernel warning, and can
panic if the kernel is booted with panic_on_warn.
This is because nilfs2 keeps buffer pointers in local structures for some
metadata and reuses them, but such buffers may be forcibly discarded by
nilfs_clear_dirty_page() in some critical situations.
This issue is reported to appear after commit 28a65b49eb53 ("nilfs2: do
not write dirty data after degenerating to read-only"), but the issue has
potentially existed before.
Fix this issue by checking the uptodate flag when attempting to reuse an
internally held buffer, and reloading the metadata instead of reusing the
buffer if the flag was lost.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i2c: cadence: cdns_i2c_master_xfer(): Fix runtime PM leak on error path
The cdns_i2c_master_xfer() function gets a runtime PM reference when the
function is entered. This reference is released when the function is
exited. There is currently one error path where the function exits
directly, which leads to a leak of the runtime PM reference.
Make sure that this error path also releases the runtime PM reference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: firewire-digi00x: prevent potential use after free
This code was supposed to return an error code if init_stream()
failed, but it instead freed dg00x->rx_stream and returned success.
This potentially leads to a use after free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio_vdpa: build affinity masks conditionally
We try to build affinity mask via create_affinity_masks()
unconditionally which may lead several issues:
- the affinity mask is not used for parent without affinity support
(only VDUSE support the affinity now)
- the logic of create_affinity_masks() might not work for devices
other than block. For example it's not rare in the networking device
where the number of queues could exceed the number of CPUs. Such
case breaks the current affinity logic which is based on
group_cpus_evenly() who assumes the number of CPUs are not less than
the number of groups. This can trigger a warning[1]:
if (ret >= 0)
WARN_ON(nr_present + nr_others < numgrps);
Fixing this by only build the affinity masks only when
- Driver passes affinity descriptor, driver like virtio-blk can make
sure to limit the number of queues when it exceeds the number of CPUs
- Parent support affinity setting config ops
This help to avoid the warning. More optimizations could be done on
top.

More optimizations could be done on\ntop.\n\n[1]\n[ 682.146655] WARNING: CPU: 6 PID: 1550 at lib/group_cpus.c:400 group_cpus_evenly+0x1aa/0x1c0\n[ 682.146668] CPU: 6 PID: 1550 Comm: vdpa Not tainted 6.5.0-rc5jason+ #79\n[ 682.146671] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.2-0-gea1b7a073390-prebuilt.qemu.org 04/01/2014\n[ 682.146673] RIP: 0010:group_cpus_evenly+0x1aa/0x1c0\n[ 682.146676] Code: 4c 89 e0 5b 5d 41 5c 41 5d 41 5e c3 cc cc cc cc e8 1b c4 74 ff 48 89 ef e8 13 ac 98 ff 4c 89 e7 45 31 e4 e8 08 ac 98 ff eb c2 \u003c0f\u003e 0b eb b6 e8 fd 05 c3 00 45 31 e4 eb e5 cc cc cc cc cc cc cc cc\n[ 682.146679] RSP: 0018:ffffc9000215f498 EFLAGS: 00010293\n[ 682.146682] RAX: 000000000001f1e0 RBX: 0000000000000041 RCX: 0000000000000000\n[ 682.146684] RDX: ffff888109922058 RSI: 0000000000000041 RDI: 0000000000000030\n[ 682.146686] RBP: ffff888109922058 R08: ffffc9000215f498 R09: ffffc9000215f4a0\n[ 682.146687] R10: 00000000000198d0 R11: 0000000000000030 R12: ffff888107e02800\n[ 682.146689] R13: 0000000000000030 R14: 0000000000000030 R15: 0000000000000041\n[ 682.146692] FS: 00007fef52315740(0000) GS:ffff888237380000(0000) knlGS:0000000000000000\n[ 682.146695] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[ 682.146696] CR2: 00007fef52509000 CR3: 0000000110dbc004 CR4: 0000000000370ee0\n[ 682.146698] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n[ 682.146700] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n[ 682.146701] Call Trace:\n[ 682.146703] \u003cTASK\u003e\n[ 682.146705] ? __warn+0x7b/0x130\n[ 682.146709] ? group_cpus_evenly+0x1aa/0x1c0\n[ 682.146712] ? report_bug+0x1c8/0x1e0\n[ 682.146717] ? handle_bug+0x3c/0x70\n[ 682.146721] ? exc_invalid_op+0x14/0x70\n[ 682.146723] ? asm_exc_invalid_op+0x16/0x20\n[ 682.146727] ? group_cpus_evenly+0x1aa/0x1c0\n[ 682.146729] ? group_cpus_evenly+0x15c/0x1c0\n[ 682.146731] create_affinity_masks+0xaf/0x1a0\n[ 682.146735] virtio_vdpa_find_vqs+0x83/0x1d0\n[ 682.146738] ? __pfx_default_calc_sets+0x10/0x10\n[ 682.146742] virtnet_find_vqs+0x1f0/0x370\n[ 682.146747] virtnet_probe+0x501/0xcd0\n[ 682.146749] ? vp_modern_get_status+0x12/0x20\n[ 682.146751] ? get_cap_addr.isra.0+0x10/0xc0\n[ 682.146754] virtio_dev_probe+0x1af/0x260\n[ 682.146759] really_probe+0x1a5/0x410"

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfp: clean mc addresses in application firmware when closing port
When moving devices from one namespace to another, mc addresses are
cleaned in software while not removed from application firmware. Thus
the mc addresses are remained and will cause resource leak.
Now use `__dev_mc_unsync` to clean mc addresses when closing port.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm: bridge: dw_hdmi: fix connector access for scdc
Commit 5d844091f237 ("drm/scdc-helper: Pimp SCDC debugs") changed the scdc
interface to pick up an i2c adapter from a connector instead. However, in
the case of dw-hdmi, the wrong connector was being used to pass i2c adapter
information, since dw-hdmi's embedded connector structure is only populated
when the bridge attachment callback explicitly asks for it.
drm-meson is handling connector creation, so this won't happen, leading to
a NULL pointer dereference.
Fix it by having scdc functions access dw-hdmi's current connector pointer
instead, which is assigned during the bridge enablement stage.
[narmstrong: moved Fixes tag before first S-o-b and added Reported-by tag]

Summary
In the Linux kernel, the following vulnerability has been resolved:
dccp: Fix out of bounds access in DCCP error handler
There was a previous attempt to fix an out-of-bounds access in the DCCP
error handlers, but that fix assumed that the error handlers only want
to access the first 8 bytes of the DCCP header. Actually, they also look
at the DCCP sequence number, which is stored beyond 8 bytes, so an
explicit pskb_may_pull() is required.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: imon: make send_packet() more robust
syzbot is reporting that imon has three problems which result in
hung tasks due to forever holding device lock [1].
First problem is that when usb_rx_callback_intf0() once got -EPROTO error
after ictx->dev_present_intf0 became true, usb_rx_callback_intf0()
resubmits urb after printk(), and resubmitted urb causes
usb_rx_callback_intf0() to again get -EPROTO error. This results in
printk() flooding (RCU stalls).
Alan Stern commented [2] that
In theory it's okay to resubmit _if_ the driver has a robust
error-recovery scheme (such as giving up after some fixed limit on the
number of errors or after some fixed time has elapsed, perhaps with a
time delay to prevent a flood of errors). Most drivers don't bother to
do this; they simply give up right away. This makes them more
vulnerable to short-term noise interference during USB transfers, but in
reality such interference is quite rare. There's nothing really wrong
with giving up right away.
but imon has a poor error-recovery scheme which just retries forever;
this behavior should be fixed.
Since I'm not sure whether it is safe for imon users to give up upon any
error code, this patch takes care of only union of error codes chosen from
modules in drivers/media/rc/ directory which handle -EPROTO error (i.e.
ir_toy, mceusb and igorplugusb).
Second problem is that when usb_rx_callback_intf0() once got -EPROTO error
before ictx->dev_present_intf0 becomes true, usb_rx_callback_intf0() always
resubmits urb due to commit 8791d63af0cf ("[media] imon: don't wedge
hardware after early callbacks"). Move the ictx->dev_present_intf0 test
introduced by commit 6f6b90c9231a ("[media] imon: don't parse scancodes
until intf configured") to immediately before imon_incoming_packet(), or
the first problem explained above happens without printk() flooding (i.e.
hung task).
Third problem is that when usb_rx_callback_intf0() is not called for some
reason (e.g. flaky hardware; the reproducer for this problem sometimes
prevents usb_rx_callback_intf0() from being called),
wait_for_completion_interruptible() in send_packet() never returns (i.e.
hung task). As a workaround for such situation, change send_packet() to
wait for completion with timeout of 10 seconds.

This results in\nprintk() flooding (RCU stalls).\n\nAlan Stern commented [2] that\n\n In theory it\u0027s okay to resubmit _if_ the driver has a robust\n error-recovery scheme (such as giving up after some fixed limit on the\n number of errors or after some fixed time has elapsed, perhaps with a\n time delay to prevent a flood of errors). Most drivers don\u0027t bother to\n do this; they simply give up right away. This makes them more\n vulnerable to short-term noise interference during USB transfers, but in\n reality such interference is quite rare. There\u0027s nothing really wrong\n with giving up right away.\n\nbut imon has a poor error-recovery scheme which just retries forever;\nthis behavior should be fixed.\n\nSince I\u0027m not sure whether it is safe for imon users to give up upon any\nerror code, this patch takes care of only union of error codes chosen from\nmodules in drivers/media/rc/ directory which handle -EPROTO error (i.e.\nir_toy, mceusb and igorplugusb).\n\nSecond problem is that when usb_rx_callback_intf0() once got -EPROTO error\nbefore ictx-\u003edev_present_intf0 becomes true, usb_rx_callback_intf0() always\nresubmits urb due to commit 8791d63af0cf (\"[media] imon: don\u0027t wedge\nhardware after early callbacks\"). Move the ictx-\u003edev_present_intf0 test\nintroduced by commit 6f6b90c9231a (\"[media] imon: don\u0027t parse scancodes\nuntil intf configured\") to immediately before imon_incoming_packet(), or\nthe first problem explained above happens without printk() flooding (i.e.\nhung task).\n\nThird problem is that when usb_rx_callback_intf0() is not called for some\nreason (e.g. flaky hardware; the reproducer for this problem sometimes\nprevents usb_rx_callback_intf0() from being called),\nwait_for_completion_interruptible() in send_packet() never returns (i.e.\nhung task). As a workaround for such situation, change send_packet() to\nwait for completion with timeout of 10 seconds."

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-multipath: fix lockdep WARN due to partition scan work
Blktests test cases nvme/014, 057 and 058 fail occasionally due to a
lockdep WARN. As reported in the Closes tag URL, the WARN indicates that
a deadlock can happen due to the dependency among disk->open_mutex,
kblockd workqueue completion and partition_scan_work completion.
To avoid the lockdep WARN and the potential deadlock, cut the dependency
by running the partition_scan_work not by kblockd workqueue but by
nvme_wq.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/efa: Fix wrong resources deallocation order
When trying to destroy QP or CQ, we first decrease the refcount and
potentially free memory regions allocated for the object and then
request the device to destroy the object. If the device fails, the
object isn't fully destroyed so the user/IB core can try to destroy the
object again which will lead to underflow when trying to decrease an
already zeroed refcount.
Deallocate resources in reverse order of allocating them to safely free
them.

Summary
In the Linux kernel, the following vulnerability has been resolved:
soc: qcom: smsm: Fix refcount leak bugs in qcom_smsm_probe()
There are two refcount leak bugs in qcom_smsm_probe():
(1) The 'local_node' is escaped out from for_each_child_of_node() as
the break of iteration, we should call of_node_put() for it in error
path or when it is not used anymore.
(2) The 'node' is escaped out from for_each_available_child_of_node()
as the 'goto', we should call of_node_put() for it in goto target.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sctp: fix a null dereference in sctp_disposition sctp_sf_do_5_1D_ce()
If new_asoc->peer.adaptation_ind=0 and sctp_ulpevent_make_authkey=0
and sctp_ulpevent_make_authkey() returns 0, then the variable
ai_ev remains zero and the zero will be dereferenced
in the sctp_ulpevent_free() function.

Any host with a listening SCTP socket (telecom SIGTRAN/M3UA/Diameter signalling nodes are routinely inter-carrier and internet facing) is remotely reachable.\nAC:L - The attacker deterministically controls both selectable preconditions by simply omitting the Adaptation Layer Indication parameter (leaving `ai_ev` NULL) and omitting the SCTP-AUTH parameters (forcing the `sctp_ulpevent_make_authkey()` call), which are the default characteristics of a plain handshake. The only remaining factor is the GFP_ATOMIC allocation failing, which the attacker can influence by flooding the target with concurrent association attempts and traffic to exhaust atomic reserves \u2014 particularly effective on the memory-constrained embedded/telecom devices where SCTP is deployed.\nPR:N - SCTP association establishment is entirely unauthenticated; the attacker only needs to complete the standard INIT / INIT-ACK / COOKIE ECHO exchange against a listening socket, with the state cookie having been minted by the victim itself. No credentials, capabilities, or local account are involved anywhere along the path.\nUI:N - Exploitation requires nothing from any local user or administrator beyond the pre-existing condition that an SCTP service is listening. The attacker drives the entire handshake unilaterally.\nS:U - The NULL dereference faults inside the kernel handling the same network stack that received the packet; there is no crossing into another security authority such as a hypervisor, IOMMU, or sandbox boundary.\nC:N - The dereference is a read of `event-\u003emsg_flags` at a fixed low offset from NULL, which faults immediately; no data is returned to the attacker and no kernel memory contents are disclosed.\nI:N - The bug is a read fault on a NULL pointer with no write, no out-of-bounds access, and no object lifetime confusion, so no kernel data is modified and no control-flow hijack primitive is produced.\nA:H - The dereference occurs in NET_RX softirq context, producing a fatal exception in interrupt \u2014 a kernel panic and complete loss of availability, or at minimum an oops that kills the softirq path (and an immediate panic on the `panic_on_oops` configurations common in embedded and telecom deployments). The attacker can repeat the attempt indefinitely across reboots."

Summary
In the Linux kernel, the following vulnerability has been resolved:
kcm: Fix memory leak in error path of kcm_sendmsg()
syzbot reported a memory leak like below:
BUG: memory leak
unreferenced object 0xffff88810b088c00 (size 240):
comm "syz-executor186", pid 5012, jiffies 4294943306 (age 13.680s)
hex dump (first 32 bytes):

[<ffffffff84c0008b>] entry_SYSCALL_64_after_hwframe+0x63/0xcd
In kcm_sendmsg(), kcm_tx_msg(head)->last_skb is used as a cursor to append
newly allocated skbs to 'head'. If some bytes are copied, an error occurred,
and jumped to out_error label, 'last_skb' is left unmodified. A later
kcm_sendmsg() will use an obsoleted 'last_skb' reference, corrupting the
'head' frag_list and causing the leak.
This patch fixes this issue by properly updating the last allocated skb in
'last_skb'.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: reject malicious packets in ipv6_gso_segment()
syzbot was able to craft a packet with very long IPv6 extension headers
leading to an overflow of skb->transport_header.
This 16bit field has a limited range.
Add skb_reset_transport_header_careful() helper and use it
from ipv6_gso_segment()

A \u003e64KB extension-header chain cannot be delivered in a single frame over any real link and GRO does not grow the header chain, so a purely remote packet cannot reach it.\nAC:L - The attacker fully controls the number and size of IPv6 extension headers, the linear-area size (`vnet_hdr.hdr_len`), the gso_type/gso_size and `csum_start`, so `skb-\u003edata - skb-\u003ehead` can be driven deterministically past 65535 and made to satisfy the `skb_checksum_start() != skb_transport_header()` guard in `tcp_gso_segment()`. No race, timing window, or memory grooming is involved.\nPR:L - A local socket is required, but `unshare -Urn` gives any unprivileged user CAP_NET_RAW and CAP_NET_ADMIN inside a fresh user+net namespace \u2014 enough to open an `AF_PACKET` socket, disable GSO offload on a veth/dummy, and transmit; the `IPV6_2292PKTOPTIONS` (64KB) plus `UDP_SEGMENT` route needs no capability at all.\nUI:N - The attacking process triggers the flaw entirely on its own by sending a packet; no victim action such as mounting, opening a file, or connecting is required.\nS:U - The truncated header offset and all resulting bad accesses stay inside the kernel\u0027s own security authority \u2014 no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - `skb_transport_header()` is left pointing at an attacker-chosen wrong location and `skb_network_header_len()` wraps to a ~64K u16, so segmentation reads header fields and copies data from out-of-bounds/unintended offsets into the emitted segments, which are then transmitted on the wire \u2014 an unbounded disclosure primitive rather than a few strictly bounded bytes.\nI:H - The corrupted offset is propagated into every segment by `__copy_skb_header()`/`skb_headers_offset_update()` (u16 arithmetic that itself wraps), and the callbacks then write `th-\u003eseq`, `th-\u003echeck`, `th-\u003efin/psh/cwr`, `uh-\u003elen`, `uh-\u003echeck` and `*prevhdr` through it, giving attacker-directed writes at offsets the kernel never validated.\nA:H - The negative `skb_transport_offset()` flows into `skb_push()`/length computations in `skb_segment()`/`skb_segment_list()` where it can trip `skb_under_panic()`, each segment forces a \u003e64KB allocation, and on `CONFIG_DEBUG_NET`/`panic_on_warn` kernels the `WARN` in `skb_reset_transport_header()` panics outright \u2014 all repeatable at will from an unprivileged process."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix peer HE MCS assignment
In ath11k_wmi_send_peer_assoc_cmd(), peer's transmit MCS is sent to
firmware as receive MCS while peer's receive MCS sent as transmit MCS,
which goes against firmwire's definition.
While connecting to a misbehaved AP that advertises 0xffff (meaning not
supported) for 160 MHz transmit MCS map, firmware crashes due to 0xffff
is assigned to he_mcs->rx_mcs_set field.
Ext Tag: HE Capabilities
[...]
Supported HE-MCS and NSS Set
[...]
Rx and Tx MCS Maps 160 MHz
[...]
Tx HE-MCS Map 160 MHz: 0xffff
Swap the assignment to fix this issue.
As the HE rate control mask is meant to limit our own transmit MCS, it
needs to go via he_mcs->rx_mcs_set field. With the aforementioned swapping
done, change is needed as well to apply it to the peer's receive MCS.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix memory leak in ocfs2_mount_volume()
There is a memory leak reported by kmemleak:
unreferenced object 0xffff88810cc65e60 (size 32):
comm "mount.ocfs2", pid 23753, jiffies 4302528942 (age 34735.105s)
hex dump (first 32 bytes):

[<ffffffff8300006a>] entry_SYSCALL_64_after_hwframe+0x46/0xb0
This call stack is related to two problems. Firstly, the ocfs2 super uses
"replay_map" to trace online/offline slots, in order to recover offline
slots during recovery and mount. But when ocfs2_truncate_log_init()
returns an error in ocfs2_mount_volume(), the memory of "replay_map" will
not be freed in error handling path. Secondly, the memory of "replay_map"
will not be freed if d_make_root() returns an error in ocfs2_fill_super().
But the memory of "replay_map" will be freed normally when completing
recovery and mount in ocfs2_complete_mount_recovery().
Fix the first problem by adding error handling path to free "replay_map"
when ocfs2_truncate_log_init() fails. And fix the second problem by
calling ocfs2_free_replay_slots(osb) in the error handling path
"out_dismount". In addition, since ocfs2_free_replay_slots() is static,
it is necessary to remove its static attribute and declare it in header
file.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: Fix UAF in hci_disconnect_all_sync
Use-after-free can occur in hci_disconnect_all_sync if a connection is
deleted by concurrent processing of a controller event.
To prevent this the code now tries to iterate over the list backwards
to ensure the links are cleanup before its parents, also it no longer
relies on a cursor, instead it always uses the last element since
hci_abort_conn_sync is guaranteed to call hci_conn_del.
UAF crash log:

The victim-side trigger (adapter power-off or the routine autosuspend path via `hci_suspend_sync()`) recurs constantly, and attempts can be retried indefinitely.\nPR:N - The attacker needs no account, capability, or credential on the target host \u2014 only an in-range Bluetooth link, which for LE/L2CAP/CIS can be established without pairing. No local privilege on the victim is required to deliver the disconnect that frees the `hci_conn`.\nUI:N - `hci_disconnect_all_sync()` is reached automatically by `hci_suspend_sync()` on every system/auto suspend that has active connections, and by rfkill/adapter power-down performed by system daemons. No deliberate victim action is needed.\nS:U - The corruption stays within the kernel\u0027s own security authority; there is no crossing into a hypervisor, IOMMU, or other separate security scope.\nC:H - The freed `hci_conn` is read after free (`conn-\u003estate`, `conn-\u003ehandle`, `conn-\u003etype`, `conn-\u003edst`) from a sprayable general kmalloc cache, letting an attacker who reallocates the slot both leak kernel memory contents and steer subsequent reads for arbitrary disclosure.\nI:H - The dangling object is passed on to `hci_conn_failed()`/`hci_conn_del()`, which performs `list_del` on attacker-controlled list pointers (write primitive) and calls the `conn-\u003ecleanup(conn)` function pointer out of freed memory in `hci_conn_cleanup()`, giving control-flow hijack and privilege escalation potential.\nA:H - The confirmed KASAN slab-use-after-free in the `hci_cmd_sync_work` kernel worker crashes the kernel, and it can be re-triggered on every power-off/suspend cycle for persistent denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: Fix device use-after-free on unbind
A recent change fixed device reference leaks when looking up drm
platform device driver data during bind() but failed to remove a partial
fix which had been added by commit 80805b62ea5b ("drm/mediatek: Fix
kobject put for component sub-drivers").
This results in a reference imbalance on component bind() failures and
on unbind() which could lead to a user-after-free.
Make sure to only drop the references after retrieving the driver data
by effectively reverting the previous partial fix.
Note that holding a reference to a device does not prevent its driver
data from going away so there is no point in keeping the reference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda: cs35l41: Fix NULL pointer dereference in cs35l41_hda_read_acpi()
The acpi_get_first_physical_node() function can return NULL, in which
case the get_device() function also returns NULL, but this value is
then dereferenced without checking,so add a check to prevent a crash.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

==================================================================
In the above issue, ioctl invokes the swap_inode_boot_loader function to
swap inode<5> and inode<12>. However, inode<5> contain incorrect imode and
disordered extents, and i_nlink is set to 1. The extents check for inode in
the ext4_iget function can be bypassed bacause 5 is EXT4_BOOT_LOADER_INO.
While links_count is set to 1, the extents are not initialized in
swap_inode_boot_loader. After the ioctl command is executed successfully,
the extents are swapped to inode<12>, in this case, run the `cat` command
to view inode<12>. And Bug_ON is triggered due to the incorrect extents.
When the boot loader inode is not initialized, its imode can be one of the
following:
1) the imode is a bad type, which is marked as bad_inode in ext4_iget and
set to S_IFREG.
2) the imode is good type but not S_IFREG.
3) the imode is S_IFREG.
The BUG_ON may be triggered by bypassing the check in cases 1 and 2.
Therefore, when the boot loader inode is bad_inode or its imode is not
S_IFREG, initialize the inode to avoid triggering the BUG.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vhost_vdpa: fix the crash in unmap a large memory
While testing in vIOMMU, sometimes Guest will unmap very large memory,
which will cause the crash. To fix this, add a new function
vhost_vdpa_general_unmap(). This function will only unmap the memory
that saved in iotlb.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs: drop peer group ids under namespace lock
When cleaning up peer group ids in the failure path we need to make sure
to hold on to the namespace lock. Otherwise another thread might just
turn the mount from a shared into a non-shared mount concurrently.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommufd: Don't overflow during division for dirty tracking
If pgshift is 63 then BITS_PER_TYPE(*bitmap->bitmap) * pgsize will overflow
to 0 and this triggers divide by 0.
In this case the index should just be 0, so reorganize things to divide
by shift and avoid hitting any overflows.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommufd: Set end correctly when doing batch carry
Even though the test suite covers this it somehow became obscured that
this wasn't working.
The test iommufd_ioas.mock_domain.access_domain_destory would blow up
rarely.
end should be set to 1 because this just pushed an item, the carry, to the
pfns list.
Sometimes the test would blow up with:
BUG: kernel NULL pointer dereference, address: 0000000000000000

No network or physical access is involved.\nAC:L - The attacker fully controls every precondition: hugepage-backed source memory for the contiguous PFN run, the overlapping area layout via IOMMU_IOAS_COPY, and the exact unmap offset that lands the hole/used boundary mid-run. Once the layout is arranged the `end=0` desynchronization and the resulting over-walk in batch_unpin() are deterministic; only the severity of the resulting garbage varies.\nPR:L - iommufd_fops_open() and the ioctl dispatcher perform no capability check whatsoever \u2014 access is gated only by permissions on /dev/iommu, which are routinely granted to unprivileged service accounts (qemu/libvirt for device passthrough, DPDK/SPDK users). An unprivileged local user with that device access can drive the entire path.\nUI:N - The full sequence \u2014 map, copy, attach, unmap/destroy \u2014 is performed by the attacker\u0027s own process with no victim action required.\nS:C - This breaks the invariant the code explicitly documents (\"For security we must not unpin something that is still DMA mapped\"): pages still mapped into a live IOMMU domain get their refcount dropped, so they can be freed and reallocated while an assigned device \u2014 programmed by a guest VM or by VFIO userspace \u2014 retains DMA access to them. That is an IOMMU/DMA boundary bypass reaching resources beyond iommufd\u0027s security authority.\nC:H - batch_unpin() walks past `end` with no bound check, reading adjacent kernel stack (the on-stack `u64 backup[32]` array) as PFNs, and the resulting refcount underflow frees pages that remain IOMMU-mapped and are then reallocated to arbitrary consumers \u2014 giving a device or attacker read access to reused kernel/user memory.\nI:H - The over-walk performs unpin_user_page_range_dirty_lock() and set_page_dirty on attacker-influenced wild struct page pointers, yielding an arbitrary refcount-decrement primitive plus premature page free (use-after-free) \u2014 a well-known route to heap grooming, arbitrary write and privilege escalation. The inflated index also drives iommu_unmap() over IOVA ranges beyond the intended area.\nA:H - The commit message documents a reproducible NULL pointer dereference oops in batch_unpin+0xa2 during iommufd_hw_pagetable_destroy, on a non-failable destroy path that holds pages-\u003emutex, so the crash also wedges other iommufd users. Any use-after-free from the refcount underflow crashes the kernel as well."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm: fix workqueue leak on bind errors
Make sure to destroy the workqueue also in case of early errors during
bind (e.g. a subcomponent failing to bind).
Since commit c3b790ea07a1 ("drm: Manage drm_mode_config_init with
drmm_") the mode config will be freed when the drm device is released
also when using the legacy interface, but add an explicit cleanup for
consistency and to facilitate backporting.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: zoned: skip splitting and logical rewriting on pre-alloc write
When doing a relocation, there is a chance that at the time of
btrfs_reloc_clone_csums(), there is no checksum for the corresponding
region.
In this case, btrfs_finish_ordered_zoned()'s sum points to an invalid item
and so ordered_extent's logical is set to some invalid value. Then,
btrfs_lookup_block_group() in btrfs_zone_finish_endio() failed to find a
block group and will hit an assert or a null pointer dereference as
following.
This can be reprodcued by running btrfs/028 several times (e.g, 4 to 16
times) with a null_blk setup. The device's zone size and capacity is set to
32 MB and the storage size is set to 5 GB on my setup.

</TASK>
On the zoned mode, writing to pre-allocated region means data relocation
write. Such write always uses WRITE command so there is no need of splitting
and rewriting logical address. Thus, we can just skip the function for the
case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
kcm: Fix error handling for SOCK_DGRAM in kcm_sendmsg().
syzkaller found a memory leak in kcm_sendmsg(), and commit c821a88bd720
("kcm: Fix memory leak in error path of kcm_sendmsg()") suppressed it by
updating kcm_tx_msg(head)->last_skb if partial data is copied so that the
following sendmsg() will resume from the skb.
However, we cannot know how many bytes were copied when we get the error.
Thus, we could mess up the MSG_MORE queue.
When kcm_sendmsg() fails for SOCK_DGRAM, we should purge the queue as we
do so for UDP by udp_flush_pending_frames().
Even without this change, when the error occurred, the following sendmsg()
resumed from a wrong skb and the queue was messed up. However, we have
yet to get such a report, and only syzkaller stumbled on it. So, this
can be changed safely.
Note this does not change SOCK_SEQPACKET behaviour.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sched: act_ife: initialize struct tc_ife to fix KMSAN kernel-infoleak
Fix a KMSAN kernel-infoleak detected by the syzbot .
[net?] KMSAN: kernel-infoleak in __skb_datagram_iter
In tcf_ife_dump(), the variable 'opt' was partially initialized using a
designatied initializer. While the padding bytes are reamined
uninitialized. nla_put() copies the entire structure into a
netlink message, these uninitialized bytes leaked to userspace.
Initialize the structure with memset before assigning its fields
to ensure all members and padding are cleared prior to beign copied.
This change silences the KMSAN report and prevents potential information
leaks from the kernel memory.
This fix has been tested and validated by syzbot. This patch closes the
bug reported at the following syzkaller link and ensures no infoleak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_ct: add seqadj extension for natted connections
Sequence adjustment may be required for FTP traffic with PASV/EPSV modes.
due to need to re-write packet payload (IP, port) on the ftp control
connection. This can require changes to the TCP length and expected
seq / ack_seq.
The easiest way to reproduce this issue is with PASV mode.
Example ruleset:
table inet ftp_nat {
ct helper ftp_helper {
type "ftp" protocol tcp
l3proto inet
}
chain prerouting {
type filter hook prerouting priority 0; policy accept;
tcp dport 21 ct state new ct helper set "ftp_helper"
}
}
table ip nat {
chain prerouting {
type nat hook prerouting priority -100; policy accept;
tcp dport 21 dnat ip prefix to ip daddr map {
192.168.100.1 : 192.168.13.2/32 }
}
chain postrouting {
type nat hook postrouting priority 100 ; policy accept;
tcp sport 21 snat ip prefix to ip saddr map {
192.168.13.2 : 192.168.100.1/32 }
}
}
Note that the ftp helper gets assigned *after* the dnat setup.
The inverse (nat after helper assign) is handled by an existing
check in nf_nat_setup_info() and will not show the problem.
Topoloy:
+-------------------+ +----------------------------------+
| FTP: 192.168.13.2 | <-> | NAT: 192.168.13.3, 192.168.100.1 |
+-------------------+ +----------------------------------+
|
+-----------------------+
| Client: 192.168.100.2 |
+-----------------------+
ftp nat changes do not work as expected in this case:
Connected to 192.168.100.1.
[..]
ftp> epsv
EPSV/EPRT on IPv4 off.
ftp> ls
227 Entering passive mode (192,168,100,1,209,129).
421 Service not available, remote server has closed connection.
Kernel logs:
Missing nfct_seqadj_ext_add() setup call
WARNING: CPU: 1 PID: 0 at net/netfilter/nf_conntrack_seqadj.c:41

..
Fix this by adding the required extension when a conntrack helper is assigned
to a connection that has a nat binding.

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

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix NULL deref in debugfs odm_combine_segments
When a connector is connected but inactive (e.g., disabled by desktop
environments), pipe_ctx->stream_res.tg will be destroyed. Then, reading
odm_combine_segments causes kernel NULL pointer dereference.
BUG: kernel NULL pointer dereference, address: 0000000000000000

Fix amdgpu_bo_validate_size() to check whether the TTM domain manager for the
requested memory exists, else we get a kernel oops when dereferencing "man".
v2: Make the patch standalone, i.e. not dependent on local patches.
v3: Preserve old behaviour and just check that the manager pointer is not
NULL.
v4: Complain if GTT domain requested and it is uninitialized--most likely a
bug.

No race, timing window, or uncontrollable precondition is involved.\nPR:L - VMW_EXECBUF is declared DRM_RENDER_ALLOW and vmwgfx sets DRIVER_RENDER, so no DRM master or authentication is needed \u2014 any unprivileged local user with access to the render node (standard for graphics/desktop users and containers in VMware guests) can submit commands.\nUI:N - The attacker triggers the flaw entirely on their own by issuing the execbuf ioctl with a crafted SVGA3D command header. No victim action or interaction is required.\nS:U - The integer overflow and the resulting out-of-bounds accesses occur within the guest kernel\u0027s own address space and are confined to the kernel\u0027s security authority. No hypervisor, IOMMU, or sandbox boundary is crossed by the kernel-side defect itself.\nC:H - The unchecked header-\u003esize drives pointer arithmetic in vmw_cmd_dma(), vmw_cmd_draw(), and vmw_cmd_tex_state(), producing large out-of-bounds reads of adjacent kernel memory whose contents are interpreted as resource handles; success/failure of vmw_user_resource_lookup_handle() forms a scanning oracle over kernel heap contents, so arbitrary kernel memory disclosure is achievable.\nI:H - The same overflow yields out-of-bounds writes \u2014 vmw_cmd_dma() writes bo_size into suffix-\u003emaximumOffset past the buffer, and OOB-derived relocation offsets cause vmw_resource_relocations_apply() to write 32-bit resource IDs outside the command buffer. Controlled heap corruption of this kind is a standard path to privilege escalation.\nA:H - A header-\u003esize of 0xFFFFFFF8 makes *size zero, causing vmw_cmd_check_all() to spin forever while holding dev_priv-\u003ecmdbuf_mutex, and the far out-of-bounds reads past a vmalloc\u0027d bounce buffer hit a guard page and oops the kernel. Either outcome is a full denial of service."

Summary
In the Linux kernel, the following vulnerability has been resolved:
md/raid10: fix memleak for 'conf->bio_split'
In the error path of raid10_run(), 'conf' need be freed, however,
'conf->bio_split' is missed and memory will be leaked.
Since there are 3 places to free 'conf', factor out a helper to fix the
problem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: read sk->sk_family once in sk_mc_loop()
syzbot is playing with IPV6_ADDRFORM quite a lot these days,
and managed to hit the WARN_ON_ONCE(1) in sk_mc_loop()
We have many more similar issues to fix.

xdp->frame_sz > PAGE_SIZE check was introduced in commit c8741e2bfe87
("xdp: Allow bpf_xdp_adjust_tail() to grow packet size"). But Jesper
Dangaard Brouer <jbrouer@redhat.com> noted that after introducing the
xdp_init_buff() which all XDP driver use - it's safe to remove this
check. The original intend was to catch cases where XDP drivers have
not been updated to use xdp.frame_sz, but that is not longer a concern
(since xdp_init_buff).
Running the initial syzkaller repro it was discovered that the
contiguous physical memory allocation is used for both xdp paths in
tun_get_user(), e.g. tun_build_skb() and tun_alloc_skb(). It was also
stated by Jesper Dangaard Brouer <jbrouer@redhat.com> that XDP can
work on higher order pages, as long as this is contiguous physical
memory (e.g. a page).

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/srpt: Add a check for valid 'mad_agent' pointer
When unregistering MAD agent, srpt module has a non-null check
for 'mad_agent' pointer before invoking ib_unregister_mad_agent().
This check can pass if 'mad_agent' variable holds an error value.
The 'mad_agent' can have an error value for a short window when
srpt_add_one() and srpt_remove_one() is executed simultaneously.
In srpt module, added a valid pointer check for 'sport->mad_agent'
before unregistering MAD agent.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: uas: fix urb unmapping issue when the uas device is remove during ongoing data transfer
When a UAS device is unplugged during data transfer, there is
a probability of a system panic occurring. The root cause is
an access to an invalid memory address during URB callback handling.
Specifically, this happens when the dma_direct_unmap_sg() function
is called within the usb_hcd_unmap_urb_for_dma() interface, but the
sg->dma_address field is 0 and the sg data structure has already been
freed.
The SCSI driver sends transfer commands by invoking uas_queuecommand_lck()
in uas.c, using the uas_submit_urbs() function to submit requests to USB.
Within the uas_submit_urbs() implementation, three URBs (sense_urb,
data_urb, and cmd_urb) are sequentially submitted. Device removal may
occur at any point during uas_submit_urbs execution, which may result
in URB submission failure. However, some URBs might have been successfully
submitted before the failure, and uas_submit_urbs will return the -ENODEV
error code in this case. The current error handling directly calls
scsi_done(). In the SCSI driver, this eventually triggers scsi_complete()
to invoke scsi_end_request() for releasing the sgtable. The successfully
submitted URBs, when being unlinked to giveback, call
usb_hcd_unmap_urb_for_dma() in hcd.c, leading to exceptions during sg
unmapping operations since the sg data structure has already been freed.
This patch modifies the error condition check in the uas_submit_urbs()
function. When a UAS device is removed but one or more URBs have already
been successfully submitted to USB, it avoids immediately invoking
scsi_done() and save the cmnd to devinfo->cmnd array. If the successfully
submitted URBs is completed before devinfo->resetting being set, then
the scsi_done() function will be called within uas_try_complete() after
all pending URB operations are finalized. Otherwise, the scsi_done()
function will be called within uas_zap_pending(), which is executed after
usb_kill_anchored_urbs().
The error handling only takes effect when uas_queuecommand_lck() calls
uas_submit_urbs() and returns the error value -ENODEV . In this case,
the device is disconnected, and the flow proceeds to uas_disconnect(),
where uas_zap_pending() is invoked to call uas_try_complete().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: da7219: Fix an error handling path in da7219_register_dai_clks()
If clk_hw_register() fails, the corresponding clk should not be
unregistered.
To handle errors from loops, clean up partial iterations before doing the
goto. So add a clk_hw_unregister().
Then use a while (--i >= 0) loop in the unwind section.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-fc: use lock accessing port_state and rport state
nvme_fc_unregister_remote removes the remote port on a lport object at
any point in time when there is no active association. This races with
with the reconnect logic, because nvme_fc_create_association is not
taking a lock to check the port_state and atomically increase the
active count on the rport.

Summary
In the Linux kernel, the following vulnerability has been resolved:
comedi: multiq3: sanitize config options in multiq3_attach()
Syzbot identified an issue [1] in multiq3_attach() that induces a
task timeout due to open() or COMEDI_DEVCONFIG ioctl operations,
specifically, in the case of multiq3 driver.
This problem arose when syzkaller managed to craft weird configuration
options used to specify the number of channels in encoder subdevice.
If a particularly great number is passed to s->n_chan in
multiq3_attach() via it->options[2], then multiple calls to
multiq3_encoder_reset() at the end of driver-specific attach() method
will be running for minutes, thus blocking tasks and affected devices
as well.
While this issue is most likely not too dangerous for real-life
devices, it still makes sense to sanitize configuration inputs. Enable
a sensible limit on the number of encoder chips (4 chips max, each
with 2 channels) to stop this behaviour from manifesting.
[1] Syzbot crash:
INFO: task syz.2.19:6067 blocked for more than 143 seconds.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ixgbe: Fix panic during XDP_TX with > 64 CPUs
Commit 4fe815850bdc ("ixgbe: let the xdpdrv work with more than 64 cpus")
adds support to allow XDP programs to run on systems with more than
64 CPUs by locking the XDP TX rings and indexing them using cpu % 64
(IXGBE_MAX_XDP_QS).
Upon trying this out patch on a system with more than 64 cores,
the kernel paniced with an array-index-out-of-bounds at the return in
ixgbe_determine_xdp_ring in ixgbe.h, which means ixgbe_determine_xdp_q_idx
was just returning the cpu instead of cpu % IXGBE_MAX_XDP_QS. An example
splat:

I think this is how it happens:
Upon loading the first XDP program on a system with more than 64 CPUs,
ixgbe_xdp_locking_key is incremented in ixgbe_xdp_setup. However,
immediately after this, the rings are reconfigured by ixgbe_setup_tc.
ixgbe_setup_tc calls ixgbe_clear_interrupt_scheme which calls
ixgbe_free_q_vectors which calls ixgbe_free_q_vector in a loop.
ixgbe_free_q_vector decrements ixgbe_xdp_locking_key once per call if
it is non-zero. Commenting out the decrement in ixgbe_free_q_vector
stopped my system from panicing.
I suspect to make the original patch work, I would need to load an XDP
program and then replace it in order to get ixgbe_xdp_locking_key back
above 0 since ixgbe_setup_tc is only called when transitioning between
XDP and non-XDP ring configurations, while ixgbe_xdp_locking_key is
incremented every time ixgbe_xdp_setup is called.
Also, ixgbe_setup_tc can be called via ethtool --set-channels, so this
becomes another path to decrement ixgbe_xdp_locking_key to 0 on systems
with more than 64 CPUs.
Since ixgbe_xdp_locking_key only protects the XDP_TX path and is tied
to the number of CPUs present, there is no reason to disable it upon
unloading an XDP program. To avoid confusion, I have moved enabling
ixgbe_xdp_locking_key into ixgbe_sw_init, which is part of the probe path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xen: speed up grant-table reclaim
When a grant entry is still in use by the remote domain, Linux must put
it on a deferred list. Normally, this list is very short, because
the PV network and block protocols expect the backend to unmap the grant
first. However, Qubes OS's GUI protocol is subject to the constraints
of the X Window System, and as such winds up with the frontend unmapping
the window first. As a result, the list can grow very large, resulting
in a massive memory leak and eventual VM freeze.
To partially solve this problem, make the number of entries that the VM
will attempt to free at each iteration tunable. The default is still
10, but it can be overridden via a module parameter.
This is Cc: stable because (when combined with appropriate userspace
changes) it fixes a severe performance and stability problem for Qubes
OS users.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xen/events: Return -EEXIST for bound VIRQs
Change find_virq() to return -EEXIST when a VIRQ is bound to a
different CPU than the one passed in. With that, remove the BUG_ON()
from bind_virq_to_irq() to propogate the error upwards.
Some VIRQs are per-cpu, but others are per-domain or global. Those must
be bound to CPU0 and can then migrate elsewhere. The lookup for
per-domain and global will probably fail when migrated off CPU 0,
especially when the current CPU is tracked. This now returns -EEXIST
instead of BUG_ON().
A second call to bind a per-domain or global VIRQ is not expected, but
make it non-fatal to avoid trying to look up the irq, since we don't
know which per_cpu(virq_to_irq) it will be in.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: Fix UAF on kernel BO VA nodes
If the MMU is down, panthor_vm_unmap_range() might return an error.
We expect the page table to be updated still, and if the MMU is blocked,
the rest of the GPU should be blocked too, so no risk of accessing
physical memory returned to the system (which the current code doesn't
cover for anyway).
Proceed with the rest of the cleanup instead of bailing out and leaving
the va_node inserted in the drm_mm, which leads to UAF when other
adjacent nodes are removed from the drm_mm tree.

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: sc16is7xx: setup GPIO controller later in probe
The GPIO controller component of the sc16is7xx driver is setup too
early, which can result in a race condition where another device tries
to utilise the GPIO lines before the sc16is7xx device has finished
initialising.
This issue manifests itself as an Oops when the GPIO lines are configured:
Unable to handle kernel read from unreadable memory at virtual address
...
pc : sc16is7xx_gpio_direction_output+0x68/0x108 [sc16is7xx]
lr : sc16is7xx_gpio_direction_output+0x4c/0x108 [sc16is7xx]
...

This patch moves the setup of the GPIO controller functions to later in the
probe function, ensuring the sc16is7xx device has already finished
initialising by the time other devices try to make use of the GPIO lines.
The error handling has also been reordered to reflect the new
initialisation order.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: Fix a null-ptr access in the cursor snooper
Check that the resource which is converted to a surface exists before
trying to use the cursor snooper on it.
vmw_cmd_res_check allows explicit invalid (SVGA3D_INVALID_ID) identifiers
because some svga commands accept SVGA3D_INVALID_ID to mean "no surface",
unfortunately functions that accept the actual surfaces as objects might
(and in case of the cursor snooper, do not) be able to handle null
objects. Make sure that we validate not only the identifier (via the
vmw_cmd_res_check) but also check that the actual resource exists before
trying to do something with it.
Fixes unchecked null-ptr reference in the snooping code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-iocost: fix divide by 0 error in calc_lcoefs()
echo max of u64 to cost.model can cause divide by 0 error.
# echo 8:0 rbps=18446744073709551615 > /sys/fs/cgroup/io.cost.model
divide error: 0000 [#1] PREEMPT SMP

calc_lcoefs() uses the input value of cost.model in DIV_ROUND_UP_ULL,
overflow would happen if bps plus IOC_PAGE_SIZE is greater than
ULLONG_MAX, it can cause divide by 0 error.
Fix the problem by setting basecost

Summary
In the Linux kernel, the following vulnerability has been resolved:
misc: pci_endpoint_test: Free IRQs before removing the device
In pci_endpoint_test_remove(), freeing the IRQs after removing the device
creates a small race window for IRQs to be received with the test device
memory already released, causing the IRQ handler to access invalid memory,
resulting in an oops.
Free the device IRQs before removing the device to avoid this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/secretmem: fix use-after-free race in fault handler
When a page fault occurs in a secret memory file created with
`memfd_secret(2)`, the kernel will allocate a new folio for it, mark the
underlying page as not-present in the direct map, and add it to the file
mapping.
If two tasks cause a fault in the same page concurrently, both could end
up allocating a folio and removing the page from the direct map, but only
one would succeed in adding the folio to the file mapping. The task that
failed undoes the effects of its attempt by (a) freeing the folio again
and (b) putting the page back into the direct map. However, by doing
these two operations in this order, the page becomes available to the
allocator again before it is placed back in the direct mapping.
If another task attempts to allocate the page between (a) and (b), and the
kernel tries to access it via the direct map, it would result in a
supervisor not-present page fault.
Fix the ordering to restore the direct map before the folio is freed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ipw2200: fix memory leak in ipw_wdev_init()
In the error path of ipw_wdev_init(), exception value is returned, and
the memory applied for in the function is not released. Also the memory
is not released in ipw_pci_probe(). As a result, memory leakage occurs.
So memory release needs to be added to the error path of ipw_wdev_init().

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: anysee: fix null-ptr-deref in anysee_master_xfer
In anysee_master_xfer, msg is controlled by user. When msg[i].buf
is null and msg[i].len is zero, former checks on msg[i].buf would be
passed. Malicious data finally reach anysee_master_xfer. If accessing
msg[i].buf[0] without sanity check, null ptr deref would happen.
We add check on msg[i].len to prevent crash.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ip6_vti: fix slab-use-after-free in decode_session6
When ipv6_vti device is set to the qdisc of the sfb type, the cb field
of the sent skb may be modified during enqueuing. Then,
slab-use-after-free may occur when ipv6_vti device sends IPv6 packets.
The stack information is as follows:

The buggy address belongs to the object at ffff88802e08ed00
which belongs to the cache skbuff_small_head of size 640
The buggy address is located 194 bytes inside of
freed 640-byte region [ffff88802e08ed00, ffff88802e08ef80)
As commit f855691975bb ("xfrm6: Fix the nexthdr offset in
_decode_session6.") showed, xfrm_decode_session was originally intended
only for the receive path. IP6CB(skb)->nhoff is not set during
transmission. Therefore, set the cb field in the skb to 0 before
sending packets.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: fix refcount leak in nfsd_set_fh_dentry()
nfsd exports a "pseudo root filesystem" which is used by NFSv4 to find
the various exported filesystems using LOOKUP requests from a known root
filehandle. NFSv3 uses the MOUNT protocol to find those exported
filesystems and so is not given access to the pseudo root filesystem.
If a v3 (or v2) client uses a filehandle from that filesystem,
nfsd_set_fh_dentry() will report an error, but still stores the export
in "struct svc_fh" even though it also drops the reference (exp_put()).
This means that when fh_put() is called an extra reference will be dropped
which can lead to use-after-free and possible denial of service.
Normal NFS usage will not provide a pseudo-root filehandle to a v3
client. This bug can only be triggered by the client synthesising an
incorrect filehandle.
To fix this we move the assignments to the svc_fh later, after all
possible error cases have been detected.

Summary
In the Linux kernel, the following vulnerability has been resolved:
smc: Use __sk_dst_get() and dst_dev_rcu() in smc_clc_prfx_match().
smc_clc_prfx_match() is called from smc_listen_work() and
not under RCU nor RTNL.
Using sk_dst_get(sk)->dev could trigger UAF.
Let's use __sk_dst_get() and dst_dev_rcu().
Note that the returned value of smc_clc_prfx_match() is not
used in the caller.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: toshsd: fix return value check of mmc_add_host()
mmc_add_host() may return error, if we ignore its return value, the memory
that allocated in mmc_alloc_host() will be leaked and it will lead a kernel
crash because of deleting not added device in the remove path.
So fix this by checking the return value and goto error path which will call
mmc_free_host(), besides, free_irq() also needs be called.

In the Linux kernel, the following vulnerability has been resolved:
crypto: marvell/octeontx - prevent integer overflows
The "code_length" value comes from the firmware file. If your firmware
is untrusted realistically there is probably very little you can do to
protect yourself. Still we try to limit the damage as much as possible.
Also Smatch marks any data read from the filesystem as untrusted and
prints warnings if it not capped correctly.
The "code_length * 2" can overflow. The round_up(ucode_size, 16) +
sizeof() expression can overflow too. Prevent these overflows.

Summary
In the Linux kernel, the following vulnerability has been resolved:
opp: Fix use-after-free in lazy_opp_tables after probe deferral
When dev_pm_opp_of_find_icc_paths() in _allocate_opp_table() returns
-EPROBE_DEFER, the opp_table is freed again, to wait until all the
interconnect paths are available.
However, if the OPP table is using required-opps then it may already
have been added to the global lazy_opp_tables list. The error path
does not remove the opp_table from the list again.
This can cause crashes later when the provider of the required-opps
is added, since we will iterate over OPP tables that have already been
freed. E.g.:
Unable to handle kernel NULL pointer dereference when read
CPU: 0 PID: 7 Comm: kworker/0:0 Not tainted 6.4.0-rc3
PC is at _of_add_opp_table_v2 (include/linux/of.h:949
drivers/opp/of.c:98 drivers/opp/of.c:344 drivers/opp/of.c:404
drivers/opp/of.c:1032) -> lazy_link_required_opp_table()
Fix this by calling _of_clear_opp_table() to remove the opp_table from
the list and clear other allocated resources. While at it, also add the
missing mutex_destroy() calls in the error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rsi: Do not configure WoWlan in shutdown hook if not enabled
In case WoWlan was never configured during the operation of the system,
the hw->wiphy->wowlan_config will be NULL. rsi_config_wowlan() checks
whether wowlan_config is non-NULL and if it is not, then WARNs about it.
The warning is valid, as during normal operation the rsi_config_wowlan()
should only ever be called with non-NULL wowlan_config. In shutdown this
rsi_config_wowlan() should only ever be called if WoWlan was configured
before by the user.
Add checks for non-NULL wowlan_config into the shutdown hook. While at it,
check whether the wiphy is also non-NULL before accessing wowlan_config .
Drop the single-use wowlan_config variable, just inline it into function
call.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: aspeed - fix double free caused by devm
The clock obtained via devm_clk_get_enabled() is automatically managed
by devres and will be disabled and freed on driver detach. Manually
calling clk_disable_unprepare() in error path and remove function
causes double free.
Remove the manual clock cleanup in both aspeed_acry_probe()'s error
path and aspeed_acry_remove().

Summary
In the Linux kernel, the following vulnerability has been resolved:
irqchip/mchp-eic: Fix error code in mchp_eic_domain_alloc()
If irq_domain_translate_twocell() sets "hwirq" to >= MCHP_EIC_NIRQ (2) then
it results in an out of bounds access.
The code checks for invalid values, but doesn't set the error code. Return
-EINVAL in that case, instead of returning success.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix BUG in ext4_mb_new_inode_pa() due to overflow
When we calculate the end position of ext4_free_extent, this position may
be exactly where ext4_lblk_t (i.e. uint) overflows. For example, if
ac_g_ex.fe_logical is 4294965248 and ac_orig_goal_len is 2048, then the
computed end is 0x100000000, which is 0. If ac->ac_o_ex.fe_logical is not
the first case of adjusting the best extent, that is, new_bex_end > 0, the
following BUG_ON will be triggered:
=========================================================
kernel BUG at fs/ext4/mballoc.c:5116!
invalid opcode: 0000 [#1] PREEMPT SMP PTI
CPU: 3 PID: 673 Comm: xfs_io Tainted: G E 6.5.0-rc1+ #279
RIP: 0010:ext4_mb_new_inode_pa+0xc5/0x430
Call Trace:

iomap_dio_rw+0x16/0x80
=========================================================
A simple reproducer demonstrating the problem:
mkfs.ext4 -F /dev/sda -b 4096 100M
mount /dev/sda /tmp/test
fallocate -l1M /tmp/test/tmp
fallocate -l10M /tmp/test/file
fallocate -i -o 1M -l16777203M /tmp/test/file
fsstress -d /tmp/test -l 0 -n 100000 -p 8 &
sleep 10 && killall -9 fsstress
rm -f /tmp/test/tmp
xfs_io -c "open -ad /tmp/test/file" -c "pwrite -S 0xff 0 8192"
We simply refactor the logic for adjusting the best extent by adding
a temporary ext4_free_extent ex and use extent_logical_end() to avoid
overflow, which also simplifies the code.

In the Linux kernel, the following vulnerability has been resolved:
MIPS: KVM: Fix NULL pointer dereference

The root cause is the deletion of kvm_mips_commpage_init() leaves vcpu
->arch.cop0 NULL. So fix it by making cop0 from a pointer to an embedded
object.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: MGMT: fix crash in set_mesh_sync and set_mesh_complete
There is a BUG: KASAN: stack-out-of-bounds in set_mesh_sync due to
memcpy from badly declared on-stack flexible array.
Another crash is in set_mesh_complete() due to double list_del via
mgmt_pending_valid + mgmt_pending_remove.
Use DEFINE_FLEX to declare the flexible array right, and don't memcpy
outside bounds.
As mgmt_pending_valid removes the cmd from list, use mgmt_pending_free,
and also report status on error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Don't redirect packets with invalid pkt_len
Syzbot found an issue [1]: fq_codel_drop() try to drop a flow whitout any
skbs, that is, the flow->head is null.
The root cause, as the [2] says, is because that bpf_prog_test_run_skb()
run a bpf prog which redirects empty skbs.
So we should determine whether the length of the packet modified by bpf
prog or others like bpf_prog_test is valid before forwarding it directly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: htc_hst: free skb in ath9k_htc_rx_msg() if there is no callback function
It is stated that ath9k_htc_rx_msg() either frees the provided skb or
passes its management to another callback function. However, the skb is
not freed in case there is no another callback function, and Syzkaller was
able to cause a memory leak. Also minor comment fix.
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: mte: Avoid setting PG_mte_tagged if no tags cleared or restored
Prior to commit 69e3b846d8a7 ("arm64: mte: Sync tags for pages where PTE
is untagged"), mte_sync_tags() was only called for pte_tagged() entries
(those mapped with PROT_MTE). Therefore mte_sync_tags() could safely use
test_and_set_bit(PG_mte_tagged, &page->flags) without inadvertently
setting PG_mte_tagged on an untagged page.
The above commit was required as guests may enable MTE without any
control at the stage 2 mapping, nor a PROT_MTE mapping in the VMM.
However, the side-effect was that any page with a PTE that looked like
swap (or migration) was getting PG_mte_tagged set automatically. A
subsequent page copy (e.g. migration) copied the tags to the destination
page even if the tags were owned by KASAN.
This issue was masked by the page_kasan_tag_reset() call introduced in
commit e5b8d9218951 ("arm64: mte: reset the page tag in page->flags").
When this commit was reverted (20794545c146), KASAN started reporting
access faults because the overriding tags in a page did not match the
original page->flags (with CONFIG_KASAN_HW_TAGS=y):
BUG: KASAN: invalid-access in copy_page+0x10/0xd0 arch/arm64/lib/copy_page.S:26
Read at addr f5ff000017f2e000 by task syz-executor.1/2218
Pointer tag: [f5], memory tag: [f2]
Move the PG_mte_tagged bit setting from mte_sync_tags() to the actual
place where tags are cleared (mte_sync_page_tags()) or restored
(mte_restore_tags()).

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/pseries: Rework lppaca_shared_proc() to avoid DEBUG_PREEMPT
lppaca_shared_proc() takes a pointer to the lppaca which is typically
accessed through get_lppaca(). With DEBUG_PREEMPT enabled, this leads
to checking if preemption is enabled, for example:
BUG: using smp_processor_id() in preemptible [00000000] code: grep/10693
caller is lparcfg_data+0x408/0x19a0
CPU: 4 PID: 10693 Comm: grep Not tainted 6.5.0-rc3 #2
Call Trace:
dump_stack_lvl+0x154/0x200 (unreliable)
check_preemption_disabled+0x214/0x220
lparcfg_data+0x408/0x19a0
...
This isn't actually a problem however, as it does not matter which
lppaca is accessed, the shared proc state will be the same.
vcpudispatch_stats_procfs_init() already works around this by disabling
preemption, but the lparcfg code does not, erroring any time
/proc/powerpc/lparcfg is accessed with DEBUG_PREEMPT enabled.
Instead of disabling preemption on the caller side, rework
lppaca_shared_proc() to not take a pointer and instead directly access
the lppaca, bypassing any potential preemption checks.
[mpe: Rework to avoid needing a definition in paca.h and lppaca.h]

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dpu: Disallow unallocated resources to be returned
In the event that the topology requests resources that have not been
created by the system (because they are typically not represented in
dpu_mdss_cfg ^1), the resource(s) in global_state (in this case DSC
blocks, until their allocation/assignment is being sanity-checked in
"drm/msm/dpu: Reject topologies for which no DSC blocks are available")
remain NULL but will still be returned out of
dpu_rm_get_assigned_resources, where the caller expects to get an array
containing num_blks valid pointers (but instead gets these NULLs).
To prevent this from happening, where null-pointer dereferences
typically result in a hard-to-debug platform lockup, num_blks shouldn't
increase past NULL blocks and will print an error and break instead.
After all, max_blks represents the static size of the maximum number of
blocks whereas the actual amount varies per platform.
^1: which can happen after a git rebase ended up moving additions to
_dpu_cfg to a different struct which has the same patch context.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix potential overflow of PCM transfer buffer
The PCM stream data in USB-audio driver is transferred over USB URB
packet buffers, and each packet size is determined dynamically. The
packet sizes are limited by some factors such as wMaxPacketSize USB
descriptor. OTOH, in the current code, the actually used packet sizes
are determined only by the rate and the PPS, which may be bigger than
the size limit above. This results in a buffer overflow, as reported
by syzbot.
Basically when the limit is smaller than the calculated packet size,
it implies that something is wrong, most likely a weird USB
descriptor. So the best option would be just to return an error at
the parameter setup time before doing any further operations.
This patch introduces such a sanity check, and returns -EINVAL when
the packet size is greater than maxpacksize. The comparison with
ep->packsize[1] alone should suffice since it's always equal or
greater than ep->packsize[0].

The\npacket sizes are limited by some factors such as wMaxPacketSize USB\ndescriptor. OTOH, in the current code, the actually used packet sizes\nare determined only by the rate and the PPS, which may be bigger than\nthe size limit above. This results in a buffer overflow, as reported\nby syzbot.\n\nBasically when the limit is smaller than the calculated packet size,\nit implies that something is wrong, most likely a weird USB\ndescriptor. So the best option would be just to return an error at\nthe parameter setup time before doing any further operations.\n\nThis patch introduces such a sanity check, and returns -EINVAL when\nthe packet size is greater than maxpacksize. The comparison with\nep-\u003epacksize[1] alone should suffice since it\u0027s always equal or\ngreater than ep-\u003epacksize[0]."

Although a malformed descriptor is one way to reach it, no physical interaction is required for a local attacker on a machine with an attached USB audio device.\nAC:L - The attacker deterministically chooses the rate and sample format that make `packsize[1] * stride` exceed the `wMaxPacketSize`-derived buffer, then triggers the copy by starting playback \u2014 no race, no memory-layout guessing, and the condition is fully reproducible on every URB submission.\nPR:L - Only access to the ALSA PCM device node is required, which is granted to the logged-in session user via logind ACLs or membership in the `audio` group; no CAP_SYS_ADMIN or root is needed.\nUI:N - The attacking process performs open/hw_params/prepare/write entirely on its own; no victim action is needed, and on desktop/Android systems PipeWire/AudioFlinger will even drive the stream automatically on hotplug.\nS:U - The corruption stays within the kernel\u0027s own memory and the USB host controller\u0027s DMA-coherent pool, managed by the same security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:H - The oversized `iso_frame_desc` lengths cause the host controller to DMA kernel memory beyond the allocated coherent buffer out to the USB device, disclosing adjacent kernel heap contents to the attacker; heap corruption can also be leveraged for broader arbitrary read.\nI:H - `copy_to_urb()` memcpy\u0027s an attacker-controlled length of attacker-controlled PCM bytes past the end of the coherent URB buffer, giving a heap out-of-bounds write with controlled content \u2014 a primitive suitable for corrupting adjacent objects and hijacking control flow.\nA:H - Overrunning the DMA-coherent transfer buffer corrupts neighbouring kernel/DMA-pool memory and reliably produces an oops or panic, as observed in the syzbot report and the related bugzilla crash reports."

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: Avoid use-after-free in dbg for hci_add_adv_monitor()
KSAN reports use-after-free in hci_add_adv_monitor().
While adding an adv monitor,
hci_add_adv_monitor() calls ->
msft_add_monitor_pattern() calls ->
msft_add_monitor_sync() calls ->
msft_le_monitor_advertisement_cb() calls in an error case ->
hci_free_adv_monitor() which frees the *moniter.
This is referenced by bt_dev_dbg() in hci_add_adv_monitor().
Fix the bt_dev_dbg() by using handle instead of monitor->handle.

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/dcssblk: fix kernel crash with list_add corruption
Commit fb08a1908cb1 ("dax: simplify the dax_device <-> gendisk
association") introduced new logic for gendisk association, requiring
drivers to explicitly call dax_add_host() and dax_remove_host().
For dcssblk driver, some dax_remove_host() calls were missing, e.g. in
device remove path. The commit also broke error handling for out_dax case
in device add path, resulting in an extra put_device() w/o the previous
get_device() in that case.
This lead to stale xarray entries after device add / remove cycles. In the
case when a previously used struct gendisk pointer (xarray index) would be
used again, because blk_alloc_disk() happened to return such a pointer, the
xa_insert() in dax_add_host() would fail and go to out_dax, doing the extra
put_device() in the error path. In combination with an already flawed error
handling in dcssblk (device_register() cleanup), which needs to be
addressed in a separate patch, this resulted in a missing device_del() /
klist_del(), and eventually in the kernel crash with list_add corruption on
a subsequent device_add() / klist_add().
Fix this by adding the missing dax_remove_host() calls, and also move the
put_device() in the error path to restore the previous logic.

Summary
In the Linux kernel, the following vulnerability has been resolved:
erofs: kill hooked chains to avoid loops on deduplicated compressed images
After heavily stressing EROFS with several images which include a
hand-crafted image of repeated patterns for more than 46 days, I found
two chains could be linked with each other almost simultaneously and
form a loop so that the entire loop won't be submitted. As a
consequence, the corresponding file pages will remain locked forever.
It can be _only_ observed on data-deduplicated compressed images.
For example, consider two chains with five pclusters in total:
Chain 1: 2->3->4->5 -- The tail pcluster is 5;
Chain 2: 5->1->2 -- The tail pcluster is 2.
Chain 2 could link to Chain 1 with pcluster 5; and Chain 1 could link
to Chain 2 at the same time with pcluster 2.
Since hooked chains are all linked locklessly now, I have no idea how
to simply avoid the race. Instead, let's avoid hooked chains completely
until I could work out a proper way to fix this and end users finally
tell us that it's needed to add it back.
Actually, this optimization can be found with multi-threaded workloads
(especially even more often on deduplicated compressed images), yet I'm
not sure about the overall system impacts of not having this compared
with implementation complexity.

it's memory address. Otherwise, the list will be damaged. Also should call
bch_cannibalize_unlock() to release the btree_cache_alloc_lock and wake_up
other waiters.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: hif_usb: fix memory leak of urbs in ath9k_hif_usb_dealloc_tx_urbs()
Syzkaller reports a long-known leak of urbs in
ath9k_hif_usb_dealloc_tx_urbs().
The cause of the leak is that usb_get_urb() is called but usb_free_urb()
(or usb_put_urb()) is not called inside usb_kill_urb() as urb->dev or
urb->ep fields have not been initialized and usb_kill_urb() returns
immediately.
The patch removes trying to kill urbs located in hif_dev->tx.tx_buf
because hif_dev->tx.tx_buf is not supposed to contain urbs which are in
pending state (the pending urbs are stored in hif_dev->tx.tx_pending).
The tx.tx_lock is acquired so there should not be any changes in the list.
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix invalid prog->stats access when update_effective_progs fails
Syzkaller triggers an invalid memory access issue following fault
injection in update_effective_progs. The issue can be described as
follows:
__cgroup_bpf_detach
update_effective_progs
compute_effective_progs
bpf_prog_array_alloc <-- fault inject
purge_effective_progs
/* change to dummy_bpf_prog */
array->items[index] = &dummy_bpf_prog.prog
---softirq start---
__do_softirq
...
__cgroup_bpf_run_filter_skb
__bpf_prog_run_save_cb
bpf_prog_run
stats = this_cpu_ptr(prog->stats)
/* invalid memory access */
flags = u64_stats_update_begin_irqsave(&stats->syncp)
---softirq end---
static_branch_dec(&cgroup_bpf_enabled_key[atype])
The reason is that fault injection caused update_effective_progs to fail
and then changed the original prog into dummy_bpf_prog.prog in
purge_effective_progs. Then a softirq came, and accessing the members of
dummy_bpf_prog.prog in the softirq triggers invalid mem access.
To fix it, skip updating stats when stats is NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: tegra210-quad: Fix timeout handling
When the CPU that the QSPI interrupt handler runs on (typically CPU 0)
is excessively busy, it can lead to rare cases of the IRQ thread not
running before the transfer timeout is reached.
While handling the timeouts, any pending transfers are cleaned up and
the message that they correspond to is marked as failed, which leaves
the curr_xfer field pointing at stale memory.
To avoid this, clear curr_xfer to NULL upon timeout and check for this
condition when the IRQ thread is finally run.
While at it, also make sure to clear interrupts on failure so that new
interrupts can be run.
A better, more involved, fix would move the interrupt clearing into a
hard IRQ handler. Ideally we would also want to signal that the IRQ
thread no longer needs to be run after the timeout is hit to avoid the
extra check for a valid transfer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: ptdma: check for null desc before calling pt_cmd_callback
Resolves a panic that can occur on AMD systems, typically during host
shutdown, after the PTDMA driver had been exercised. The issue was
the pt_issue_pending() function is mistakenly assuming that there will
be at least one descriptor in the Submitted queue when the function
is called. However, it is possible that both the Submitted and Issued
queues could be empty, which could result in pt_cmd_callback() being
mistakenly called with a NULL pointer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: akcipher - default implementation for setting a private key
Changes from v1:
* removed the default implementation from set_pub_key: it is assumed that
an implementation must always have this callback defined as there are
no use case for an algorithm, which doesn't need a public key
Many akcipher implementations (like ECDSA) support only signature
verifications, so they don't have all callbacks defined.
Commit 78a0324f4a53 ("crypto: akcipher - default implementations for
request callbacks") introduced default callbacks for sign/verify
operations, which just return an error code.
However, these are not enough, because before calling sign the caller would
likely call set_priv_key first on the instantiated transform (as the
in-kernel testmgr does). This function does not have a default stub, so the
kernel crashes, when trying to set a private key on an akcipher, which
doesn't support signature generation.
I've noticed this, when trying to add a KAT vector for ECDSA signature to
the testmgr.
With this patch the testmgr returns an error in dmesg (as it should)
instead of crashing the kernel NULL ptr dereference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: fix race in hci_cmd_sync_dequeue_once
hci_cmd_sync_dequeue_once() does lookup and then cancel
the entry under two separate lock sections. Meanwhile,
hci_cmd_sync_work() can also delete the same entry,
leading to double list_del() and "UAF".
Fix this by holding cmd_sync_work_lock across both
lookup and cancel, so that the entry cannot be removed
concurrently.

In the critical scenario, rx-gro-list GRO-ed packets are fed, via a
bridge, both to the local input path and to an egress device (tun).
The segmentation of such packets unsafely writes to the cloned skbs
with shared heads.
This change addresses the issue by uncloning as needed the
to-be-segmented skbs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: nsh: Use correct mac_offset to unwind gso skb in nsh_gso_segment()
As the call trace shows, skb_panic was caused by wrong skb->mac_header
in nsh_gso_segment():
invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI
CPU: 3 PID: 2737 Comm: syz Not tainted 6.3.0-next-20230505 #1
RIP: 0010:skb_panic+0xda/0xe0

The root cause is:
nsh_gso_segment() use skb->network_header - nhoff to reset mac_header
in skb_gso_error_unwind() if inner-layer protocol gso fails.
However, skb->network_header may be reset by inner-layer protocol
gso function e.g. mpls_gso_segment. skb->mac_header reset by the
inaccurate network_header will be larger than skb headroom.
nsh_gso_segment
nhoff = skb->network_header - skb->mac_header;
__skb_pull(skb,nsh_len)
skb_mac_gso_segment

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - fix out-of-bounds read
When preparing an AER-CTR request, the driver copies the key provided by
the user into a data structure that is accessible by the firmware.
If the target device is QAT GEN4, the key size is rounded up by 16 since
a rounded up size is expected by the device.
If the key size is rounded up before the copy, the size used for copying
the key might be bigger than the size of the region containing the key,
causing an out-of-bounds read.
Fix by doing the copy first and then update the keylen.
This is to fix the following warning reported by KASAN:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: prevent NULL pointer deref during reload
Calling ethtool during reload can lead to call trace, because VSI isn't
configured for some time, but netdev is alive.
To fix it add rtnl lock for VSI deconfig and config. Set ::num_q_vectors
to 0 after freeing and add a check for ::tx/rx_rings in ring related
ethtool ops.
Add proper unroll of filters in ice_start_eth().
Reproduction:
$watch -n 0.1 -d 'ethtool -g enp24s0f0np0'
$devlink dev reload pci/0000:18:00.0 action driver_reinit
Call trace before fix:

Summary
In the Linux kernel, the following vulnerability has been resolved:
md/raid10: fix null-ptr-deref in raid10_sync_request
init_resync() inits mempool and sets conf->have_replacemnt at the beginning
of sync, close_sync() frees the mempool when sync is completed.
After [1] recovery might be skipped and init_resync() is called but
close_sync() is not. null-ptr-deref occurs with r10bio->dev[i].repl_bio.
The following is one way to reproduce the issue.
1) create a array, wait for resync to complete, mddev->recovery_cp is set
to MaxSector.
2) recovery is woken and it is skipped. conf->have_replacement is set to
0 in init_resync(). close_sync() not called.
3) some io errors and rdev A is set to WantReplacement.
4) a new device is added and set to A's replacement.
5) recovery is woken, A have replacement, but conf->have_replacemnt is
0. r10bio->dev[i].repl_bio will not be alloced and null-ptr-deref
occurs.
Fix it by not calling init_resync() if recovery skipped.
[1] commit 7e83ccbecd60 ("md/raid10: Allow skipping recovery when clean arrays are assembled")

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: mts64: fix possible null-ptr-defer in snd_mts64_interrupt
I got a null-ptr-defer error report when I do the following tests
on the qemu platform:
make defconfig and CONFIG_PARPORT=m, CONFIG_PARPORT_PC=m,
CONFIG_SND_MTS64=m
Then making test scripts:
cat>test_mod1.sh<<EOF
modprobe snd-mts64
modprobe snd-mts64
EOF
Executing the script, perhaps several times, we will get a null-ptr-defer
report, as follow:
syzkaller:~# ./test_mod.sh
snd_mts64: probe of snd_mts64.0 failed with error -5
modprobe: ERROR: could not insert 'snd_mts64': No such device
BUG: kernel NULL pointer dereference, address: 0000000000000000
#PF: supervisor write access in kernel mode

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: TC, Fix internal port memory leak
The flow rule can be splited, and the extra post_act rules are added
to post_act table. It's possible to trigger memleak when the rule
forwards packets from internal port and over tunnel, in the case that,
for example, CT 'new' state offload is allowed. As int_port object is
assigned to the flow attribute of post_act rule, and its refcnt is
incremented by mlx5e_tc_int_port_get(), but mlx5e_tc_int_port_put() is
not called, the refcnt is never decremented, then int_port is never
freed.
The kmemleak reports the following error:
unreferenced object 0xffff888128204b80 (size 64):

So fix this by moving int_port cleanup code to the flow attribute
free helper, which is used by all the attribute free cases.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: av7110: prevent underflow in write_ts_to_decoder()
The buf[4] value comes from the user via ts_play(). It is a value in
the u8 range. The final length we pass to av7110_ipack_instant_repack()
is "len - (buf[4] + 1) - 4" so add a check to ensure that the length is
not negative. It's not clear that passing a negative len value does
anything bad necessarily, but it's not best practice.
With the new bounds checking the "if (!len)" condition is no longer
possible or required so remove that.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: ipu3-imgu: Fix NULL pointer dereference in active selection access
What the IMGU driver did was that it first acquired the pointers to active
and try V4L2 subdev state, and only then figured out which one to use.
The problem with that approach and a later patch (see Fixes: tag) is that
as sd_state argument to v4l2_subdev_get_try_crop() et al is NULL, there is
now an attempt to dereference that.
Fix this.
Also rewrap lines a little.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: avoid referencing uninit memory in ath9k_wmi_ctrl_rx
For the reasons also described in commit b383e8abed41 ("wifi: ath9k: avoid
uninit memory read in ath9k_htc_rx_msg()"), ath9k_htc_rx_msg() should
validate pkt_len before accessing the SKB.
For example, the obtained SKB may have been badly constructed with
pkt_len = 8. In this case, the SKB can only contain a valid htc_frame_hdr
but after being processed in ath9k_htc_rx_msg() and passed to
ath9k_wmi_ctrl_rx() endpoint RX handler, it is expected to have a WMI
command header which should be located inside its data payload.
Implement sanity checking inside ath9k_wmi_ctrl_rx(). Otherwise, uninit
memory can be referenced.
Tested on Qualcomm Atheros Communications AR9271 802.11n .
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix potential memory leak in ext4_fc_record_modified_inode()
As krealloc may return NULL, in this case 'state->fc_modified_inodes'
may not be freed by krealloc, but 'state->fc_modified_inodes' already
set NULL. Then will lead to 'state->fc_modified_inodes' memory leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: idmouse: fix an uninit-value in idmouse_open
In idmouse_create_image, if any ftip_command fails, it will
go to the reset label. However, this leads to the data in
bulk_in_buffer[HEADER..IMGSIZE] uninitialized. And the check
for valid image incurs an uninitialized dereference.
Fix this by moving the check before reset label since this
check only be valid if the data after bulk_in_buffer[HEADER]
has concrete data.
Note that this is found by KMSAN, so only kernel compilation
is tested.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_eem: Fix memory leak in eem_unwrap
The existing code did not handle the failure case of usb_ep_queue in the
command path, potentially leading to memory leaks.
Improve error handling to free all allocated resources on usb_ep_queue
failure. This patch continues to use goto logic for error handling, as the
existing error handling is complex and not easily adaptable to auto-cleanup
helpers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: accel: bmc150: Fix irq assumption regression
The code in bmc150-accel-core.c unconditionally calls
bmc150_accel_set_interrupt() in the iio_buffer_setup_ops,
such as on the runtime PM resume path giving a kernel
splat like this if the device has no interrupts:
Unable to handle kernel NULL pointer dereference at virtual
address 00000001 when read
PC is at bmc150_accel_set_interrupt+0x98/0x194
LR is at __pm_runtime_resume+0x5c/0x64
(...)
Call trace:
bmc150_accel_set_interrupt from bmc150_accel_buffer_postenable+0x40/0x108
bmc150_accel_buffer_postenable from __iio_update_buffers+0xbe0/0xcbc
__iio_update_buffers from enable_store+0x84/0xc8
enable_store from kernfs_fop_write_iter+0x154/0x1b4
This bug seems to have been in the driver since the beginning,
but it only manifests recently, I do not know why.
Store the IRQ number in the state struct, as this is a common
pattern in other drivers, then use this to determine if we have
IRQ support or not.

JFS_SBI(ipbmap->i_sb)->bmap wasn't set to NULL after kfree() in
dbUnmount().
Syzkaller uses faultinject to reproduce this KASAN double-free
warning. The issue is triggered if either diMount() or dbMount() fail
in jfs_remount(), since diUnmount() or dbUnmount() already happened in
such a case - they will do double-free on next execution: jfs_umount
or jfs_remount.
Tested on both upstream and jfs-next by syzkaller.

No network or adjacent-network path exists into JFS mount handling.\nAC:L - The attacker deterministically forces dbMount() to fail on the remount re-read, because jfs_mount_rw() calls truncate_inode_pages() on ipbmap first: mutating the backing store so the bmap descriptor fails the sanity checks yields -EINVAL, and truncating it yields -EIO from read_metapage(). No race and no condition outside the attacker\u0027s control is involved.\nPR:L - Untrusted JFS media is routinely mounted and remounted on behalf of unprivileged users on kiosks, embedded/automotive and Android-class devices via udisks/autofs and mount-ro-then-remount-rw boot flows, and semi-privileged container/service contexts can drive the same path; consistent with sibling JFS crafted-image CVEs, a low-privileged local actor is assumed rather than full init-namespace root.\nUI:N - The attacker drives the whole sequence \u2014 mount read-only, remount read-write with a poisoned/erroring backing store, then unmount \u2014 with no victim action required at any step.\nS:U - The freed struct bmap, the slab it lives in, and all corrupted state belong to the kernel\u0027s own memory-management authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Before the second kfree(), dbSync() reads the already-freed bmap and writes over a kilobyte of its contents \u2014 including all 128 db_agfree[] entries \u2014 into the on-disk bmap descriptor, which the attacker reads back from the device, leaking freed kernel heap memory; the double-free itself further yields arbitrary read via overlapping allocations.\nI:H - A double-free of a ~1.6 KiB object in the sprayable kmalloc-2k cache lets the attacker reclaim it and hand two owners the same allocation, a classic type-confusion path to arbitrary kernel write; additionally, since jfs_remount() clears SB_RDONLY even on failure, dbAlloc()/dbFree() subsequently write through the dangling bmap pointer.\nA:H - The bug was reported by syzbot as a KASAN double-free that corrupts SLUB freelist state; with freelist hardening or slub_debug this is an immediate kernel panic, and unchecked it produces allocator corruption and crashes."

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers: dio: fix possible memory leak in dio_init()
If device_register() returns error, the 'dev' and name needs be
freed. Add a release function, and then call put_device() in the
error path, so the name is freed in kobject_cleanup() and to the
'dev' is freed in release function.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/sprd: Release dma buffer to avoid memory leak
When attaching to a domain, the driver would alloc a DMA buffer which
is used to store address mapping table, and it need to be released
when the IOMMU domain is freed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/vmem: split pages when debug pagealloc is enabled
Since commit bb1520d581a3 ("s390/mm: start kernel with DAT enabled")
the kernel crashes early during boot when debug pagealloc is enabled:
mem auto-init: stack:off, heap alloc:off, heap free:off
addressing exception: 0005 ilc:2 [#1] SMP DEBUG_PAGEALLOC

This is caused by using large mappings on machines with EDAT1/EDAT2. Add
the code to split the mappings into 4k pages if debug pagealloc is enabled
by CONFIG_DEBUG_PAGEALLOC_ENABLE_DEFAULT or the debug_pagealloc kernel
command line option.

Summary
In the Linux kernel, the following vulnerability has been resolved:
md/raid1: stop mdx_raid1 thread when raid1 array run failed
fail run raid1 array when we assemble array with the inactive disk only,
but the mdx_raid1 thread were not stop, Even if the associated resources
have been released. it will caused a NULL dereference when we do poweroff.
This causes the following Oops:

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: SVM: Get source vCPUs from source VM for SEV-ES intrahost migration
Fix a goof where KVM tries to grab source vCPUs from the destination VM
when doing intrahost migration. Grabbing the wrong vCPU not only hoses
the guest, it also crashes the host due to the VMSA pointer being left
NULL.
BUG: unable to handle page fault for address: ffffe38687000000

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Fix skb refcnt race after locking changes
There is a race where skb's from the sk_psock_backlog can be referenced
after userspace side has already skb_consumed() the sk_buff and its refcnt
dropped to zer0 causing use after free.
The flow is the following:
while ((skb = skb_peek(&psock->ingress_skb))
sk_psock_handle_Skb(psock, skb, ..., ingress)
if (!ingress) ...
sk_psock_skb_ingress
sk_psock_skb_ingress_enqueue(skb)
msg->skb = skb
sk_psock_queue_msg(psock, msg)
skb_dequeue(&psock->ingress_skb)
The sk_psock_queue_msg() puts the msg on the ingress_msg queue. This is
what the application reads when recvmsg() is called. An application can
read this anytime after the msg is placed on the queue. The recvmsg hook
will also read msg->skb and then after user space reads the msg will call
consume_skb(skb) on it effectively free'ing it.
But, the race is in above where backlog queue still has a reference to
the skb and calls skb_dequeue(). If the skb_dequeue happens after the
user reads and free's the skb we have a use after free.
The !ingress case does not suffer from this problem because it uses
sendmsg_*(sk, msg) which does not pass the sk_buff further down the
stack.
The following splat was observed with 'test_progs -t sockmap_listen':

[ 1022.726201][ T2556] </TASK>
To fix we add an skb_get() before passing the skb to be enqueued in the
engress queue. This bumps the skb->users refcnt so that consume_skb()
and kfree_skb will not immediately free the sk_buff. With this we can
be sure the skb is still around when we do the dequeue. Then we just
need to decrement the refcnt or free the skb in the backlog case which
we do by calling kfree_skb() on the ingress case as well as the sendmsg
case.
Before locking change from fixes tag we had the sock locked so we
couldn't race with user and there was no issue here.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Silence a warning in btf_type_id_size()
syzbot reported a warning in [1] with the following stacktrace:

[2] PTR '(anon)' type_id=0
[3] TYPE_TAG 'a' type_id=2
[4] VAR 'a' type_id=3, linkage=static
and when the bpf_attr.btf_key_type_id = 1 (DECL_TAG),
the following WARN_ON_ONCE in btf_type_id_size() is triggered:
if (WARN_ON_ONCE(!btf_type_is_modifier(size_type) &&
!btf_type_is_var(size_type)))
return NULL;
Note that 'return NULL' is the correct behavior as we don't want
a DECL_TAG type to be used as a btf_{key,value}_type_id even
for the case like 'DECL_TAG -> STRUCT'. So there
is no correctness issue here, we just want to silence warning.
To silence the warning, I added DECL_TAG as one of kinds in
btf_type_nosize() which will cause btf_type_id_size() returning
NULL earlier without the warning.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: bcsp: receive data only if registered
Currently, bcsp_recv() can be called even when the BCSP protocol has not
been registered. This leads to a NULL pointer dereference, as shown in
the following stack trace:
KASAN: null-ptr-deref in range [0x0000000000000108-0x000000000000010f]
RIP: 0010:bcsp_recv+0x13d/0x1740 drivers/bluetooth/hci_bcsp.c:590
Call Trace:

To prevent this, ensure that the HCI_UART_REGISTERED flag is set before
processing received data. If the protocol is not registered, return
-EUNATCH.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfc: pn533: Clear nfc_target before being used
Fix a slab-out-of-bounds read that occurs in nla_put() called from
nfc_genl_send_target() when target->sensb_res_len, which is duplicated
from an nfc_target in pn533, is too large as the nfc_target is not
properly initialized and retains garbage values. Clear nfc_targets with
memset() before they are used.
Found by a modified version of syzkaller.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/irdma: Fix data race on CQP completion stats
CQP completion statistics is read lockesly in irdma_wait_event and
irdma_check_cqp_progress while it can be updated in the completion
thread irdma_sc_ccq_get_cqe_info on another CPU as KCSAN reports.
Make completion statistics an atomic variable to reflect coherent updates
to it. This will also avoid load/store tearing logic bug potentially
possible by compiler optimizations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
jbd2: fix potential buffer head reference count leak
As in 'jbd2_fc_wait_bufs' if buffer isn't uptodate, will return -EIO without
update 'journal->j_fc_off'. But 'jbd2_fc_release_bufs' will release buffer head
from ‘j_fc_off - 1’ if 'bh' is NULL will terminal release which will lead to
buffer head buffer head reference count leak.
To solve above issue, update 'journal->j_fc_off' before return -EIO.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix race when deleting free space root from the dirty cow roots list
When deleting the free space tree we are deleting the free space root
from the list fs_info->dirty_cowonly_roots without taking the lock that
protects it, which is struct btrfs_fs_info::trans_lock.
This unsynchronized list manipulation may cause chaos if there's another
concurrent manipulation of this list, such as when adding a root to it
with ctree.c:add_root_to_dirty_list().
This can result in all sorts of weird failures caused by a race, such as
the following crash:

Summary
In the Linux kernel, the following vulnerability has been resolved:
sfc: fix crash when reading stats while NIC is resetting
efx_net_stats() (.ndo_get_stats64) can be called during an ethtool
selftest, during which time nic_data->mc_stats is NULL as the NIC has
been fini'd. In this case do not attempt to fetch the latest stats
from the hardware, else we will crash on a NULL dereference:
BUG: kernel NULL pointer dereference, address: 0000000000000038
RIP efx_nic_update_stats
abridged calltrace:
efx_ef10_update_stats_pf
efx_net_stats
dev_get_stats
dev_seq_printf_stats
Skipping the read is safe, we will simply give out stale stats.
To ensure that the free in efx_ef10_fini_nic() does not race against
efx_ef10_update_stats_pf(), which could cause a TOCTTOU bug, take the
efx->stats_lock in fini_nic (it is already held across update_stats).

Summary
In the Linux kernel, the following vulnerability has been resolved:
spmi: Add a check for remove callback when removing a SPMI driver
When removing a SPMI driver, there can be a crash due to NULL pointer
dereference if it does not have a remove callback defined. This is
one such call trace observed when removing the QCOM SPMI PMIC driver:
dump_backtrace.cfi_jt+0x0/0x8
dump_stack_lvl+0xd8/0x16c
panic+0x188/0x498
__cfi_slowpath+0x0/0x214
__cfi_slowpath+0x1dc/0x214
spmi_drv_remove+0x16c/0x1e0
device_release_driver_internal+0x468/0x79c
driver_detach+0x11c/0x1a0
bus_remove_driver+0xc4/0x124
driver_unregister+0x58/0x84
cleanup_module+0x1c/0xc24 [qcom_spmi_pmic]
__do_sys_delete_module+0x3ec/0x53c
__arm64_sys_delete_module+0x18/0x28
el0_svc_common+0xdc/0x294
el0_svc+0x38/0x9c
el0_sync_handler+0x8c/0xf0
el0_sync+0x1b4/0x1c0
If a driver has all its resources allocated through devm_() APIs and
does not need any other explicit cleanup, it would not require a
remove callback to be defined. Hence, add a check for remove callback
presence before calling it when removing a SPMI driver.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: drop unnecessary user-triggerable WARN_ONCE in verifierl log
It's trivial for user to trigger "verifier log line truncated" warning,
as verifier has a fixed-sized buffer of 1024 bytes (as of now), and there are at
least two pieces of user-provided information that can be output through
this buffer, and both can be arbitrarily sized by user:
- BTF names;
- BTF.ext source code lines strings.
Verifier log buffer should be properly sized for typical verifier state
output. But it's sort-of expected that this buffer won't be long enough
in some circumstances. So let's drop the check. In any case code will
work correctly, at worst truncating a part of a single line output.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: hpsa: Fix possible memory leak in hpsa_init_one()
The hpda_alloc_ctlr_info() allocates h and its field reply_map. However, in
hpsa_init_one(), if alloc_percpu() failed, the hpsa_init_one() jumps to
clean1 directly, which frees h and leaks the h->reply_map.
Fix by calling hpda_free_ctlr_info() to release h->replay_map and h instead
free h directly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix possible use-after-free in async command interface
mlx5_cmd_cleanup_async_ctx should return only after all its callback
handlers were completed. Before this patch, the below race between
mlx5_cmd_cleanup_async_ctx and mlx5_cmd_exec_cb_handler was possible and
lead to a use-after-free:
1. mlx5_cmd_cleanup_async_ctx is called while num_inflight is 2 (i.e.
elevated by 1, a single inflight callback).
2. mlx5_cmd_cleanup_async_ctx decreases num_inflight to 1.
3. mlx5_cmd_exec_cb_handler is called, decreases num_inflight to 0 and
is about to call wake_up().
4. mlx5_cmd_cleanup_async_ctx calls wait_event, which returns
immediately as the condition (num_inflight == 0) holds.
5. mlx5_cmd_cleanup_async_ctx returns.
6. The caller of mlx5_cmd_cleanup_async_ctx frees the mlx5_async_ctx
object.
7. mlx5_cmd_exec_cb_handler goes on and calls wake_up() on the freed
object.
Fix it by syncing using a completion object. Mark it completed when
num_inflight reaches 0.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: Fix DMA mappings leak
During reallocation of RX buffers, new DMA mappings are created for
those buffers.
steps for reproduction:
while :
do
for ((i=0; i<=8160; i=i+32))
do
ethtool -G enp130s0f0 rx $i tx $i
sleep 0.5
ethtool -g enp130s0f0
done
done
This resulted in crash:

This was caused because of new buffers with different RX ring count should
substitute older ones, but those buffers were freed in
i40e_configure_rx_ring and reallocated again with i40e_alloc_rx_bi,
thus kfree on rx_bi caused leak of already mapped DMA.
Fix this by reallocating ZC with rx_bi_zc struct when BPF program loads. Additionally
reallocate back to rx_bi when BPF program unloads.
If BPF program is loaded/unloaded and XSK pools are created, reallocate
RX queues accordingly in XSP_SETUP_XSK_POOL handler.

Summary
In the Linux kernel, the following vulnerability has been resolved:
devlink: report devlink_port_type_warn source device
devlink_port_type_warn is scheduled for port devlink and warning
when the port type is not set. But from this warning it is not easy
found out which device (driver) has no devlink port set.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_conn: return ERR_PTR instead of NULL when there is no link
hci_connect_sco currently returns NULL when there is no link (i.e. when
hci_conn_link() returns NULL).
sco_connect() expects an ERR_PTR in case of any error (see line 266 in
sco.c). Thus, hcon set as NULL passes through to sco_conn_add(), which
tries to get hcon->hdev, resulting in dereferencing a NULL pointer as
reported by syzkaller.
The same issue exists for iso_connect_cis() calling hci_connect_cis().
Thus, make hci_connect_sco() and hci_connect_cis() return ERR_PTR
instead of NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sh: dma: Fix DMA channel offset calculation
Various SoCs of the SH3, SH4 and SH4A family, which use this driver,
feature a differing number of DMA channels, which can be distributed
between up to two DMAC modules. The existing implementation fails to
correctly accommodate for all those variations, resulting in wrong
channel offset calculations and leading to kernel panics.
Rewrite dma_base_addr() in order to properly calculate channel offsets
in a DMAC module. Fix dmaor_read_reg() and dmaor_write_reg(), so that
the correct DMAC module base is selected for the DMAOR register.

Summary
In the Linux kernel, the following vulnerability has been resolved:
hwrng: amd - Fix PCI device refcount leak
for_each_pci_dev() is implemented by pci_get_device(). The comment of
pci_get_device() says that it will increase the reference count for the
returned pci_dev and also decrease the reference count for the input
pci_dev @from if it is not NULL.
If we break for_each_pci_dev() loop with pdev not NULL, we need to call
pci_dev_put() to decrease the reference count. Add the missing
pci_dev_put() for the normal and error path.

The window is further made near-deterministic because the victim thread blocks on mutex_lock(\u0026mem-\u003elock) which the freeing thread holds, so it is woken onto memory that has already been mutex_destroy()\u0027d and kfree()\u0027d.\nPR:L - The map/unmap/free memory ioctls are defined with flags 0 \u2014 no capability check whatsoever; the only requirement is an open fd on /dev/kfd, which distro/ROCm udev rules grant to ordinary local users (mode 0666, render/video group, or uaccess for the seat user) on any AMD GPU workstation or GPU-compute node.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: hugetlb: avoid soft lockup when mprotect to large memory area
When calling mprotect() to a large hugetlb memory area in our customer's
workload (~300GB hugetlb memory), soft lockup was observed:

Soft lockup is not triggered with THP or base page because there is
cond_resched() called for each PMD size.
Although the soft lockup was triggered by MTE, it should be not MTE
specific. The other processing which takes long time in the loop may
trigger soft lockup too.
So add cond_resched() for hugetlb to avoid soft lockup.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: increase max link count and fix link->enc NULL pointer access
[why]
1.) dc->links[MAX_LINKS] array size smaller than actual requested.
max_connector + max_dpia + 4 virtual = 14.
increase from 12 to 14.
2.) hw_init() access null LINK_ENC for dpia non display_endpoint.
(cherry picked from commit d7f5a61e1b04ed87b008c8d327649d184dc5bb45)

ov5675_init_controls() won't clean all the allocated resources in fail
path, which may causes the memleaks. Add v4l2_ctrl_handler_free() to
prevent memleak.

autofs_wait_queue structs should be freed if their wait_ctr becomes zero.
Otherwise they will be lost.
In this case an AUTOFS_IOC_EXPIRE_MULTI ioctl is done, then a new
waitqueue struct is allocated in autofs_wait(), its initial wait_ctr
equals 2. After that wait_event_killable() is interrupted (it returns
-ERESTARTSYS), so that 'wq->name.name == NULL' condition may be not
satisfied. Actually, this condition can be satisfied when
autofs_wait_release() or autofs_catatonic_mode() is called and, what is
also important, wait_ctr is decremented in those places. Upon the exit of
autofs_wait(), wait_ctr is decremented to 1. Then the unmounting process
begins: kill_sb calls autofs_catatonic_mode(), which should have freed the
waitqueues, but it only decrements its usage counter to zero which is not
a correct behaviour.
edit:imk
This description is of course not correct. The umount performed as a result
of an expire is a umount of a mount that has been automounted, it's not the
autofs mount itself. They happen independently, usually after everything
mounted within the autofs file system has been expired away. If everything
hasn't been expired away the automount daemon can still exit leaving mounts
in place. But expires done in both cases will result in a notification that
calls autofs_wait_release() with a result status. The problem case is the
summary execution of of the automount daemon. In this case any waiting
processes won't be woken up until either they are terminated or the mount
is umounted.
end edit: imk
So in catatonic mode we should free waitqueues which counter becomes zero.
edit: imk
Initially I was concerned that the calling of autofs_wait_release() and
autofs_catatonic_mode() was not mutually exclusive but that can't be the
case (obviously) because the queue entry (or entries) is removed from the
list when either of these two functions are called. Consequently the wait
entry will be freed by only one of these functions or by the woken process
in autofs_wait() depending on the order of the calls.

Upon the exit of\nautofs_wait(), wait_ctr is decremented to 1.

The umount performed as a result\nof an expire is a umount of a mount that has been automounted, it\u0027s not the\nautofs mount itself. They happen independently, usually after everything\nmounted within the autofs file system has been expired away. If everything\nhasn\u0027t been expired away the automount daemon can still exit leaving mounts\nin place. But expires done in both cases will result in a notification that\ncalls autofs_wait_release() with a result status. The problem case is the\nsummary execution of of the automount daemon. In this case any waiting\nprocesses won\u0027t be woken up until either they are terminated or the mount\nis umounted.\nend edit: imk\n\nSo in catatonic mode we should free waitqueues which counter becomes zero.\n\nedit: imk\nInitially I was concerned that the calling of autofs_wait_release() and\nautofs_catatonic_mode() was not mutually exclusive but that can\u0027t be the\ncase (obviously) because the queue entry (or entries) is removed from the\nlist when either of these two functions are called. Consequently the wait\nentry will be freed by only one of these functions or by the woken process\nin autofs_wait() depending on the order of the calls.\nend edit: imk"

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Fix mmap write lock not release
If mmap write lock is taken while draining retry fault, mmap write lock
is not released because svm_range_restore_pages calls mmap_read_unlock
then returns. This causes deadlock and system hangs later because mmap
read or write lock cannot be taken.
Downgrade mmap write lock to read lock if draining retry fault fix this
bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ubifs: Fix memleak when insert_old_idx() failed
Following process will cause a memleak for copied up znode:
dirty_cow_znode
zn = copy_znode(c, znode);
err = insert_old_idx(c, zbr->lnum, zbr->offs);
if (unlikely(err))
return ERR_PTR(err); // No one refers to zn.
Fetch a reproducer in [Link].
Function copy_znode() is split into 2 parts: resource allocation
and znode replacement, insert_old_idx() is split in similar way,
so resource cleanup could be done in error handling path without
corrupting metadata(mem & disk).
It's okay that old index inserting is put behind of add_idx_dirt(),
old index is used in layout_leb_in_gaps(), so the two processes do
not depend on each other.

Summary
In the Linux kernel, the following vulnerability has been resolved:
comedi: check device's attached status in compat ioctls
Syzbot identified an issue [1] that crashes kernel, seemingly due to
unexistent callback dev->get_valid_routes(). By all means, this should
not occur as said callback must always be set to
get_zero_valid_routes() in __comedi_device_postconfig().
As the crash seems to appear exclusively in i386 kernels, at least,
judging from [1] reports, the blame lies with compat versions
of standard IOCTL handlers. Several of them are modified and
do not use comedi_unlocked_ioctl(). While functionality of these
ioctls essentially copy their original versions, they do not
have required sanity check for device's attached status. This,
in turn, leads to a possibility of calling select IOCTLs on a
device that has not been properly setup, even via COMEDI_DEVCONFIG.
Doing so on unconfigured devices means that several crucial steps
are missed, for instance, specifying dev->get_valid_routes()
callback.
Fix this somewhat crudely by ensuring device's attached status before
performing any ioctls, improving logic consistency between modern
and compat functions.
[1] Syzbot report:
BUG: kernel NULL pointer dereference, address: 0000000000000000

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: mediatek: vcodec: Fix potential array out-of-bounds in decoder queue_setup
variable *nplanes is provided by user via system call argument. The
possible value of q_data->fmt->num_planes is 1-3, while the value
of *nplanes can be 1-8. The array access by index i can cause array
out-of-bounds.
Fix this bug by checking *nplanes against the array size.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ipa: only reset hashed tables when supported
Last year, the code that manages GSI channel transactions switched
from using spinlock-protected linked lists to using indexes into the
ring buffer used for a channel. Recently, Google reported seeing
transaction reference count underflows occasionally during shutdown.
Doug Anderson found a way to reproduce the issue reliably, and
bisected the issue to the commit that eliminated the linked lists
and the lock. The root cause was ultimately determined to be
related to unused transactions being committed as part of the modem
shutdown cleanup activity. Unused transactions are not normally
expected (except in error cases).
The modem uses some ranges of IPA-resident memory, and whenever it
shuts down we zero those ranges. In ipa_filter_reset_table() a
transaction is allocated to zero modem filter table entries. If
hashing is not supported, hashed table memory should not be zeroed.
But currently nothing prevents that, and the result is an unused
transaction. Something similar occurs when we zero routing table
entries for the modem.
By preventing any attempt to clear hashed tables when hashing is not
supported, the reference count underflow is avoided in this case.
Note that there likely remains an issue with properly freeing unused
transactions (if they occur due to errors). This patch addresses
only the underflows that Google originally reported.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock: fix lock inversion in vsock_assign_transport()
Syzbot reported a potential lock inversion deadlock between
vsock_register_mutex and sk_lock-AF_VSOCK when vsock_linger() is called.
The issue was introduced by commit 687aa0c5581b ("vsock: Fix
transport_* TOCTOU") which added vsock_register_mutex locking in
vsock_assign_transport() around the transport->release() call, that can
call vsock_linger(). vsock_assign_transport() can be called with sk_lock
held. vsock_linger() calls sk_wait_event() that temporarily releases and
re-acquires sk_lock. During this window, if another thread hold
vsock_register_mutex while trying to acquire sk_lock, a circular
dependency is created.
Fix this by releasing vsock_register_mutex before calling
transport->release() and vsock_deassign_transport(). This is safe
because we don't need to hold vsock_register_mutex while releasing the
old transport, and we ensure the new transport won't disappear by

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915: fix race condition UAF in i915_perf_add_config_ioctl
Userspace can guess the id value and try to race oa_config object creation
with config remove, resulting in a use-after-free if we dereference the
object after unlocking the metrics_lock. For that reason, unlocking the
metrics_lock must be done after we are done dereferencing the object.
[tursulin: Manually added stable tag.]
(cherry picked from commit 49f6f6483b652108bcb73accd0204a464b922395)

There is no remote or network-facing path to `i915_perf_add_config_ioctl`.\nAC:L - The attacker controls both sides of the race, running the add and remove ioctls concurrently from its own threads, and `idr_alloc()` starts at 2 so the config id to target is trivially guessable rather than secret. The race can be retried without limit and without any precondition the attacker cannot influence.\nPR:L - Both ioctls are `DRM_RENDER_ALLOW`, so they require no DRM authentication or master status and are usable by any unprivileged local user holding the render node, which udev ACLs grant to logged-in users and which is exposed to sandboxed GPU processes and GPU containers. With the commonly deployed `dev.i915.perf_stream_paranoid=0` setting used by Intel GPU profiling tooling, the `perfmon_capable()` check is bypassed entirely, leaving only ordinary user access.\nUI:N - The attacker issues both ioctls itself from its own processes; no victim action, file open, or administrative operation is needed. The race is entirely self-driven.\nS:U - The use-after-free corrupts kernel slab memory within the same kernel security authority that the ioctl already executes in. No VM, IOMMU, or sandbox boundary is crossed by the flaw itself.\nC:H - The freed `struct i915_oa_config` is read after `kfree_rcu()`, and the stale `oa_config-\u003eid` is returned to userspace as the ioctl return value (with `oa_config-\u003euuid` additionally leaked to dmesg), giving a repeatable oracle for reading attacker-resprayed kernel heap contents. As a use-after-free on a kmalloc object it can be leveraged for broader kernel memory disclosure.\nI:H - This is a use-after-free on an attacker-groomable slab object whose lifetime the attacker fully controls, which is the standard starting point for heap-spray and cross-cache attacks yielding kernel write primitives. Memory corruption of this class is treated as exploitable for control-flow hijacking and thus high integrity impact.\nA:H - Dereferencing the freed `i915_oa_config` triggers a KASAN/hardened-allocator oops and, once the slab page is recycled or the object is reused, can panic or destabilise the kernel. The race can be repeated indefinitely by an unprivileged user to force the crash."

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtl818x: Fix potential memory leaks in rtl8180_init_rx_ring()
In rtl8180_init_rx_ring(), memory is allocated for skb packets and DMA
allocations in a loop. When an allocation fails, the previously
successful allocations are not freed on exit.
Fix that by jumping to err_free_rings label on error, which calls
rtl8180_free_rx_ring() to free the allocations. Remove the free of
rx_ring in rtl8180_init_rx_ring() error path, and set the freed
priv->rx_buf entry to null, to avoid double free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: af9005: Fix null-ptr-deref in af9005_i2c_xfer
In af9005_i2c_xfer, msg is controlled by user. When msg[i].buf
is null and msg[i].len is zero, former checks on msg[i].buf would be
passed. Malicious data finally reach af9005_i2c_xfer. If accessing
msg[i].buf[0] without sanity check, null ptr deref would happen.
We add check on msg[i].len to prevent crash.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dccp: fix data-race around dp->dccps_mss_cache
dccp_sendmsg() reads dp->dccps_mss_cache before locking the socket.
Same thing in do_dccp_getsockopt().
Add READ_ONCE()/WRITE_ONCE() annotations,
and change dccp_sendmsg() to check again dccps_mss_cache
after socket is locked.

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: mm: fix VA-range sanity check
Both create_mapping_noalloc() and update_mapping_prot() sanity-check
their 'virt' parameter, but the check itself doesn't make much sense.
The condition used today appears to be a historical accident.
The sanity-check condition:
if ((virt >= PAGE_END) && (virt < VMALLOC_START)) {
[ ... warning here ... ]
return;
}
... can only be true for the KASAN shadow region or the module region,
and there's no reason to exclude these specifically for creating and
updateing mappings.
When arm64 support was first upstreamed in commit:
c1cc1552616d0f35 ("arm64: MMU initialisation")
... the condition was:
if (virt < VMALLOC_START) {
[ ... warning here ... ]
return;
}
At the time, VMALLOC_START was the lowest kernel address, and this was
checking whether 'virt' would be translated via TTBR1.
Subsequently in commit:
14c127c957c1c607 ("arm64: mm: Flip kernel VA space")
... the condition was changed to:
if ((virt >= VA_START) && (virt < VMALLOC_START)) {
[ ... warning here ... ]
return;
}
This appear to have been a thinko. The commit moved the linear map to
the bottom of the kernel address space, with VMALLOC_START being at the
halfway point. The old condition would warn for changes to the linear
map below this, and at the time VA_START was the end of the linear map.
Subsequently we cleaned up the naming of VA_START in commit:
77ad4ce69321abbe ("arm64: memory: rename VA_START to PAGE_END")
... keeping the erroneous condition as:
if ((virt >= PAGE_END) && (virt < VMALLOC_START)) {
[ ... warning here ... ]
return;
}
Correct the condition to check against the start of the TTBR1 address
space, which is currently PAGE_OFFSET. This simplifies the logic, and
more clearly matches the "outside kernel range" message in the warning.

In the Linux kernel, the following vulnerability has been resolved:

The address being probed has some special:
cmdline_proc_show: Probe based on ftrace
cmdline_proc_show+16: Probe for the next instruction at the ftrace location
The ftrace-based kprobe does not generate kprobe::ainsn::insn, it gets
set to NULL. In arch_prepare_kprobe() it will check for:
...
prev = get_kprobe(p->addr - 1);
preempt_enable_no_resched();
if (prev && ppc_inst_prefixed(ppc_inst_read(prev->ainsn.insn))) {
...
If prev is based on ftrace, 'ppc_inst_read(prev->ainsn.insn)' will occur
with a null pointer reference. At this point prev->addr will not be a
prefixed instruction, so the check can be skipped.
Check if prev is ftrace-based kprobe before reading 'prev->ainsn.insn'
to fix this problem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
smc: Fix use-after-free in __pnet_find_base_ndev().
syzbot reported use-after-free of net_device in __pnet_find_base_ndev(),
which was called during connect(). [0]
smc_pnet_find_ism_resource() fetches sk_dst_get(sk)->dev and passes
down to pnet_find_base_ndev(), where RTNL is held. Then, UAF happened
at __pnet_find_base_ndev() when the dev is first used.
This means dev had already been freed before acquiring RTNL in
pnet_find_base_ndev().
While dev is going away, dst->dev could be swapped with blackhole_netdev,
and the dev's refcnt by dst will be released.
We must hold dev's refcnt before calling smc_pnet_find_ism_resource().
Also, smc_pnet_find_roce_resource() has the same problem.
Let's use __sk_dst_get() and dst_dev_rcu() in the two functions.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Move representor neigh cleanup to profile cleanup_tx
For IP tunnel encapsulation in ECMP (Equal-Cost Multipath) mode, as
the flow is duplicated to the peer eswitch, the related neighbour
information on the peer uplink representor is created as well.
In the cited commit, eswitch devcom unpair is moved to uplink unload
API, specifically the profile->cleanup_tx. If there is a encap rule
offloaded in ECMP mode, when one eswitch does unpair (because of
unloading the driver, for instance), and the peer rule from the peer
eswitch is going to be deleted, the use-after-free error is triggered
while accessing neigh info, as it is already cleaned up in uplink's
profile->disable, which is before its profile->cleanup_tx.
To fix this issue, move the neigh cleanup to profile's cleanup_tx
callback, and after mlx5e_cleanup_uplink_rep_tx is called. The neigh
init is moved to init_tx for symmeter.

If there is a encap rule\noffloaded in ECMP mode, when one eswitch does unpair (because of\nunloading the driver, for instance), and the peer rule from the peer\neswitch is going to be deleted, the use-after-free error is triggered\nwhile accessing neigh info, as it is already cleaned up in uplink\u0027s\nprofile-\u003edisable, which is before its profile-\u003ecleanup_tx.\n\nTo fix this issue, move the neigh cleanup to profile\u0027s cleanup_tx\ncallback, and after mlx5e_cleanup_uplink_rep_tx is called.

Summary
In the Linux kernel, the following vulnerability has been resolved:
jfs: fix uninitialized waitqueue in transaction manager
The transaction manager initialization in txInit() was not properly
initializing TxBlock[0].waitor waitqueue, causing a crash when
txEnd(0) is called on read-only filesystems.
When a filesystem is mounted read-only, txBegin() returns tid=0 to
indicate no transaction. However, txEnd(0) still gets called and
tries to access TxBlock[0].waitor via tid_to_tblock(0), but this
waitqueue was never initialized because the initialization loop
started at index 1 instead of 0.
This causes a 'non-static key' lockdep warning and system crash:
INFO: trying to register non-static key in txEnd
Fix by ensuring all transaction blocks including TxBlock[0] have
their waitqueues properly initialized during txInit().

Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/lcs: Fix return type of lcs_start_xmit()
With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),
indirect call targets are validated against the expected function
pointer prototype to make sure the call target is valid to help mitigate
ROP attacks. If they are not identical, there is a failure at run time,
which manifests as either a kernel panic or thread getting killed. A
proposed warning in clang aims to catch these at compile time, which
reveals:
drivers/s390/net/lcs.c:2090:21: error: incompatible function pointer types initializing 'netdev_tx_t (*)(struct sk_buff *, struct net_device *)' (aka 'enum netdev_tx (*)(struct sk_buff *, struct net_device *)') with an expression of type 'int (struct sk_buff *, struct net_device *)' [-Werror,-Wincompatible-function-pointer-types-strict]
.ndo_start_xmit = lcs_start_xmit,
^~~~~~~~~~~~~~
drivers/s390/net/lcs.c:2097:21: error: incompatible function pointer types initializing 'netdev_tx_t (*)(struct sk_buff *, struct net_device *)' (aka 'enum netdev_tx (*)(struct sk_buff *, struct net_device *)') with an expression of type 'int (struct sk_buff *, struct net_device *)' [-Werror,-Wincompatible-function-pointer-types-strict]
.ndo_start_xmit = lcs_start_xmit,
^~~~~~~~~~~~~~
->ndo_start_xmit() in 'struct net_device_ops' expects a return type of
'netdev_tx_t', not 'int'. Adjust the return type of lcs_start_xmit() to
match the prototype's to resolve the warning and potential CFI failure,
should s390 select ARCH_SUPPORTS_CFI_CLANG in the future.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: wcd-mbhc-v2: fix resource leaks on component remove
The MBHC resources must be released on component probe failure and
removal so can not be tied to the lifetime of the component device.
This is specifically needed to allow probe deferrals of the sound card
which otherwise fails when reprobing the codec component:
snd-sc8280xp sound: ASoC: failed to instantiate card -517
genirq: Flags mismatch irq 299. 00002001 (mbhc sw intr) vs. 00002001 (mbhc sw intr)
wcd938x_codec audio-codec: Failed to request mbhc interrupts -16
wcd938x_codec audio-codec: mbhc initialization failed
wcd938x_codec audio-codec: ASoC: error at snd_soc_component_probe on audio-codec: -16
snd-sc8280xp sound: ASoC: failed to instantiate card -16

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Return error for inconsistent extended attributes
ntfs_read_ea is called when we want to read extended attributes. There
are some sanity checks for the validity of the EAs. However, it fails to
return a proper error code for the inconsistent attributes, which might
lead to unpredicted memory accesses after return.

No network or remote protocol path exists into ntfs3 xattr handling.\nAC:L - The attacker fully controls both inputs \u2014 the on-disk `EA_INFO.size`/non-resident `ATTR_EA` layout that makes `ntfs_read_ea()` return 0 with a NULL buffer, and the `setxattr` name/value that determines the undersized `kzalloc(add)`. There is no race and no condition outside the attacker\u0027s control; the OOB write offset is deterministically chosen.\nPR:L - The `ntfs_other_xattr_handler` has an empty prefix, so a plain `user.*` xattr set by any unprivileged user on a file they own reaches `ntfs_set_ea()` with no capability check. Only an ordinary local account is needed once the crafted volume is mounted.\nUI:N - In the realistic deployment (kiosk, shared workstation, Android/embedded/automotive with udisks2 or a media daemon auto-mounting removable NTFS read-write), the attacker performs every step themselves \u2014 insert the media, then issue the syscall \u2014 with no distinct victim action required at exploitation time.\nS:U - The heap corruption occurs in kernel memory belonging to the same security authority as the vulnerable component; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - After the failed consistency check, `memcpy(p, ea_all, size)` / `ntfs_sb_write_run(..., ea_all, size, ...)` copies up to 64 KiB read out of bounds from a small `kzalloc` buffer into the file\u0027s EA, which the attacker reads back with `getxattr` \u2014 a direct, large kernel heap disclosure. The write primitive additionally enables arbitrary read via corrupted kernel structures.\nI:H - `new_ea = Add2Ptr(ea_all, size)` writes past the undersized allocation at an attacker-chosen offset (up to 64 KiB) with attacker-controlled content of attacker-controlled length, before any bounds check. This is a controlled heap out-of-bounds write suitable for corrupting adjacent slab objects and hijacking control flow.\nA:H - The bug reproduces as a KASAN use-after-free/out-of-bounds write that panics the kernel, and unconstrained slab corruption reliably crashes the system even when not exploited for escalation."

In the Linux kernel, the following vulnerability has been resolved:
USB: usbtmc: Fix direction for 0-length ioctl control messages
The syzbot fuzzer found a problem in the usbtmc driver: When a user
submits an ioctl for a 0-length control transfer, the driver does not
check that the direction is set to OUT:

Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: mxcmmc: fix return value check of mmc_add_host()
mmc_add_host() may return error, if we ignore its return value, the memory
that allocated in mmc_alloc_host() will be leaked and it will lead a kernel
crash because of deleting not added device in the remove path.
So fix this by checking the return value and goto error path which will call
mmc_free_host().

Summary
In the Linux kernel, the following vulnerability has been resolved:
seccomp: Move copy_seccomp() to no failure path.
Our syzbot instance reported memory leaks in do_seccomp() [0], similar
to the report [1]. It shows that we miss freeing struct seccomp_filter
and some objects included in it.
We can reproduce the issue with the program below [2] which calls one
seccomp() and two clone() syscalls.
The first clone()d child exits earlier than its parent and sends a
signal to kill it during the second clone(), more precisely before the
fatal_signal_pending() test in copy_process(). When the parent receives
the signal, it has to destroy the embryonic process and return -EINTR to
user space. In the failure path, we have to call seccomp_filter_release()
to decrement the filter's refcount.
Initially, we called it in free_task() called from the failure path, but
the commit 3a15fb6ed92c ("seccomp: release filter after task is fully
dead") moved it to release_task() to notify user space as early as possible
that the filter is no longer used.
To keep the change and current seccomp refcount semantics, let's move
copy_seccomp() just after the signal check and add a WARN_ON_ONCE() in
free_task() for future debugging.

Summary
In the Linux kernel, the following vulnerability has been resolved:
swiotlb: fix info leak with DMA_FROM_DEVICE
The problem I'm addressing was discovered by the LTP test covering
cve-2018-1000204.
A short description of what happens follows:
1) The test case issues a command code 00 (TEST UNIT READY) via the SG_IO
interface with: dxfer_len == 524288, dxdfer_dir == SG_DXFER_FROM_DEV
and a corresponding dxferp. The peculiar thing about this is that TUR
is not reading from the device.
2) In sg_start_req() the invocation of blk_rq_map_user() effectively
bounces the user-space buffer. As if the device was to transfer into
it. Since commit a45b599ad808 ("scsi: sg: allocate with __GFP_ZERO in
sg_build_indirect()") we make sure this first bounce buffer is
allocated with GFP_ZERO.
3) For the rest of the story we keep ignoring that we have a TUR, so the
device won't touch the buffer we prepare as if the we had a
DMA_FROM_DEVICE type of situation. My setup uses a virtio-scsi device
and the buffer allocated by SG is mapped by the function
virtqueue_add_split() which uses DMA_FROM_DEVICE for the "in" sgs (here
scatter-gather and not scsi generics). This mapping involves bouncing
via the swiotlb (we need swiotlb to do virtio in protected guest like
s390 Secure Execution, or AMD SEV).
4) When the SCSI TUR is done, we first copy back the content of the second
(that is swiotlb) bounce buffer (which most likely contains some
previous IO data), to the first bounce buffer, which contains all
zeros. Then we copy back the content of the first bounce buffer to
the user-space buffer.
5) The test case detects that the buffer, which it zero-initialized,
ain't all zeros and fails.
One can argue that this is an swiotlb problem, because without swiotlb
we leak all zeros, and the swiotlb should be transparent in a sense that
it does not affect the outcome (if all other participants are well
behaved).
Copying the content of the original buffer into the swiotlb buffer is
the only way I can think of to make swiotlb transparent in such
scenarios. So let's do just that if in doubt, but allow the driver
to tell us that the whole mapped buffer is going to be overwritten,
in which case we can preserve the old behavior and avoid the performance
impact of the extra bounce.

The peculiar thing about this is that TUR\n is not reading from the device.\n2) In sg_start_req() the invocation of blk_rq_map_user() effectively\n bounces the user-space buffer. As if the device was to transfer into\n it. Since commit a45b599ad808 (\"scsi: sg: allocate with __GFP_ZERO in\n sg_build_indirect()\") we make sure this first bounce buffer is\n allocated with GFP_ZERO.\n3) For the rest of the story we keep ignoring that we have a TUR, so the\n device won\u0027t touch the buffer we prepare as if the we had a\n DMA_FROM_DEVICE type of situation. My setup uses a virtio-scsi device\n and the buffer allocated by SG is mapped by the function\n virtqueue_add_split() which uses DMA_FROM_DEVICE for the \"in\" sgs (here\n scatter-gather and not scsi generics). This mapping involves bouncing\n via the swiotlb (we need swiotlb to do virtio in protected guest like\n s390 Secure Execution, or AMD SEV).\n4) When the SCSI TUR is done, we first copy back the content of the second\n (that is swiotlb) bounce buffer (which most likely contains some\n previous IO data), to the first bounce buffer, which contains all\n zeros. Then we copy back the content of the first bounce buffer to\n the user-space buffer.\n5) The test case detects that the buffer, which it zero-initialized,\n ain\u0027t all zeros and fails.\n\nOne can argue that this is an swiotlb problem, because without swiotlb\nwe leak all zeros, and the swiotlb should be transparent in a sense that\nit does not affect the outcome (if all other participants are well\nbehaved).\n\nCopying the content of the original buffer into the swiotlb buffer is\nthe only way I can think of to make swiotlb transparent in such\nscenarios. So let\u0027s do just that if in doubt, but allow the driver\nto tell us that the whole mapped buffer is going to be overwritten,\nin which case we can preserve the old behavior and avoid the performance\nimpact of the extra bounce."

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: release path before inode lookup during the ino lookup ioctl
During the ino lookup ioctl we can end up calling btrfs_iget() to get an
inode reference while we are holding on a root's btree. If btrfs_iget()
needs to lookup the inode from the root's btree, because it's not
currently loaded in memory, then it will need to lock another or the
same path in the same root btree. This may result in a deadlock and
trigger the following lockdep splat:

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: videobuf2: forbid remove_bufs when legacy fileio is active
vb2_ioctl_remove_bufs() call manipulates queue internal buffer list,
potentially overwriting some pointers used by the legacy fileio access
mode. Forbid that ioctl when fileio is active to protect internal queue
state between subsequent read/write calls.

No special memory layout or timing beyond attacker control is required.\nPR:L - Any local unprivileged user with access to the video device node can trigger this \u2014 desktop distros grant the active session user access via logind uaccess ACLs/the video group, and Android/embedded camera sandboxes expose these nodes directly. No CAP_SYS_ADMIN or other capability is checked on the ioctl path.\nUI:N - The attacking process performs every step itself on its own file descriptor; no victim action, mount, or plug-in event is needed.\nS:U - The corruption is confined to kernel memory within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - After the buffers are freed, __vb2_perform_fileio() still does copy_to_user(data, buf-\u003evaddr + buf-\u003epos, count) using the stale cached kernel address, disclosing up to a full frame (potentially megabytes) of freed kernel memory \u2014 reusable by kernel stacks, slab objects, or page tables \u2014 directly to userspace.\nI:H - On output/write queues the same stale pointer is used in copy_from_user(buf-\u003evaddr + buf-\u003epos, data, count), giving an attacker-controlled write of arbitrary length into freed kernel memory (vfree\u0027d vmalloc region reusable by VMAP kernel stacks, or page-allocator pages with dma-contig), a classic UAF write primitive for privilege escalation; a NULL-pointer write via b-\u003eplanes[0].bytesused also occurs.\nA:H - vb2_get_buffer() returns NULL for the removed index despite the code asserting it \"can never be NULL when using fileio\", producing a NULL-pointer dereference oops, and the use-after-free of vfree\u0027d vmalloc addresses causes unrecoverable kernel faults."
