leds: lp5860: Fix a potential double-unlock
In lp5860_device_init(), if lp5860_init_dt() fails, an already unlocked
mutex is unlocked another time.
Slightly rework how the lock is taken/released to avoid this potential
double unlock. |

| In the Linux kernel, the following vulnerability has been resolved:
drm/lima: call drm_mm_init() with a valid allocation range
lima_vm_create() is currently run before va_start and va_end are set up,
meaning they are both 0. lima_vm_create() runs drm_mm_init() with them
as arguments for the allocator, and if DRM_DEBUG_MM is enabled the
DRM_MM_BUG_ON check in drm_mm_init then fires, as seen here on
exynos4412-odroid-u2:

| In the Linux kernel, the following vulnerability has been resolved:
udf: Mark LVID buffer as uptodate before marking it dirty
When an I/O error occurs while writing the Logical Volume Integrity
Descriptor (LVID) buffer to the block device, the block layer's completion
handler (`end_buffer_write_sync()`) clears the `BH_Uptodate` flag on the
buffer. However, the buffer still contains valid LVID data in memory. If
the filesystem is subsequently remounted read-write or synced,
`udf_open_lvid()` or `udf_sync_fs()` will modify the LVID buffer and call
`mark_buffer_dirty()`. This triggers a spurious
`WARN_ON_ONCE(!buffer_uptodate(bh))` warning in `mark_buffer_dirty()`
because the buffer is not marked uptodate, even though its in-memory
contents are valid and are about to be overwritten.
To prevent this spurious warning, unconditionally set the `BH_Uptodate`
flag before calling `mark_buffer_dirty()` in `udf_open_lvid()` and
`udf_sync_fs()`. This acknowledges that the in-memory buffer is valid and
matches the workaround previously applied to `udf_close_lvid()` in commit
853a0c25baf9 ("udf: Mark LVID buffer as uptodate before marking it dirty").
Extending this workaround ensures consistent behavior across all LVID
updates.

| In the Linux kernel, the following vulnerability has been resolved:
bpf,lsm: Drop bpf_prog_free from sleepable_lsm_hooks
__bpf_prog_put_rcu() is the call_rcu() callback for non-sleepable programs.
security_bpf_prog_free() called from there fires bpf_prog_free in softirq;
if a sleepable LSM prog is attached to that hook, might_fault() BUGs:
BUG: sleeping function called from invalid context

The call_rcu/call_rcu_tasks_trace split reflects the freed program's
sleepability, not that of any attached observer.
security_bpf_prog_free() also frees prog->aux->security, which has to stay
after the grace period, so drop bpf_prog_free from sleepable_lsm_hooks
rather than move the call. Non-sleepable observers still run there. |

sched/fair: Fix overflow in update_tg_cfs_runnable()
A divide-by-zero crash is observed when running hackbench:

The divide-by-zero happens here:
if (scale_load_down(gcfs_rq->load.weight)) {
load_sum = div_u64(gcfs_rq->avg.load_sum,
scale_load_down(gcfs_rq->load.weight));
}
gcfs_rq->load.weight is an insane large value and is truncated
to the lower 32 bits by div_u64, which happen to be 0.
Using AI for investigation, the cause is a u32 overflow in
update_tg_cfs_runnable(), and flat pickup became a victim when using
tg_tasks():
u32 new_sum, divider;
...
new_sum = se->avg.runnable_avg * divider; <-- boom
The following sequence shows how this triggers the crash:
propagate_entity_load_avg()
update_tg_cfs_runnable() # u32 overflow corrupts runnable_sum
__update_load_avg_cfs_rq()
___update_load_avg() # computes insane runnable_avg
update_tg_load_avg() # propagates to tg->runnable_avg
update_cfs_group()
calc_concur_shares()
tg_tasks() # long-to-int truncation, negative nr
reweight_entity() # corrupted se->load.weight
update_load_add() # corrupted cfs_rq->load.weight
propagate_entity_load_avg()
update_tg_cfs_load()
div_u64() # divide-by-zero
Fix by widening new_sum from u32 to u64 (no need to force tg_tasks()
to return unsigned long after this fix) |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: fsl_audmix: rework runtime PM handling in probe
After pm_runtime_enable() the AUDMIX block is powered off and stays
suspended until the first runtime resume. Register writes issued between
probe() and the first resume (e.g. from DAPM or ALSA control paths)
target unpowered hardware and cause a system hang.
Fix this by calling pm_runtime_resume_and_get() immediately after
pm_runtime_enable() to power the hardware up and enable its clocks.
Release the reference afterwards with pm_runtime_put() to allow the
runtime PM framework to suspend the device and switch the regmap to
cache-only mode when idle.
When CONFIG_PM is disabled or runtime PM is not enabled, pm_runtime_*
calls are stubs that do not power up the hardware. Handle this case
explicitly by calling fsl_audmix_runtime_resume() directly so the
hardware is always initialised and its clocks are enabled, ensuring
register accesses succeed regardless of PM configuration. |
| In the Linux kernel, the following vulnerability has been resolved:
dm-pcache: validate the persisted dirty_tail chain at load
The writeback worker follows the persisted dirty_tail chain, which is
decoded from the cache device independently of the key_tail chain that
cache_replay() walks and bounds. A crafted image, whose on-media fields are
authenticated only by a crc32c with a fixed seed, can aim dirty_tail at a
chain of last ksets that never terminates, so cache_writeback_fn() re-arms
itself with no delay forever.
Walk the dirty_tail chain once at load with the same hop cap cache_replay()
uses and fail the table load with -EIO if it does not reach an end within
n_segs hops. |
| In the Linux kernel, the following vulnerability has been resolved:
i3c: master: Do not treat master device as a duplicate target
i3c_master_search_i3c_dev_duplicate() searches the bus for another I3C
device with the same PID as the reference device. The search can match
master->this, causing the controller itself to be returned as a
duplicate.
Since the controller is not a target device, it cannot be a duplicate of
one. Exclude master->this from matching so that the function only
returns real duplicate target devices. |
| go-openapi/swag jsonutils before 0.27.1 contains a stack overflow vulnerability in ordered JSON parsing and serialization due to unbounded recursion with no depth limit. Remote unauthenticated attackers can submit deeply nested JSON documents to services accepting OpenAPI specifications, causing fatal stack overflow that terminates the process and all in-flight requests. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: rk3288 - fail ahash requests on HASH idle timeout
rk_hash_run() waits for RK_CRYPTO_HASH_STS to become idle after the
final DMA transfer, but ignores the poll result. If the hash engine
never becomes idle, the driver still reads the digest registers and
finalizes the request with the previous success value.
Store the poll result and finalize the request with the timeout error
before reading the digest registers. |
| In the Linux kernel, the following vulnerability has been resolved:
hwrng: xilinx-trng - propagate timeout before any data is read
xtrng_readblock32() polls for 16-byte chunks but returns the number of
bytes read even when the first poll times out. Its caller then treats a
zero return as a short successful read, and partial reads for full
32-byte blocks can make the tail copy use a fixed block offset rather
than the amount already produced.
Return the poll error when no data has been read, preserve partial
positive returns after some data is available, stop the generator on all
collection exits, and append tail bytes at the current output count. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: atmel-ecc - reject hardware ECDH without a public key
The hardware ECDH path in atmel_ecdh_compute_shared_secret() uses the
private key stored in the device. However, the public key is cached only
after atmel_ecdh_set_secret() successfully generated that private key
for the current tfm.
atmel_ecdh_generate_public_key() already rejects requests when no public
key is cached. Add the same check to atmel_ecdh_compute_shared_secret()
to prevent the device from using a private key that was not generated
for the current tfm. |
| In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Unwind P2A receiver mailbox setup failure
mailbox_chan_setup() can request an additional P2A receiver channel after
successfully acquiring the primary P2A channel. If that later request
fails, the function returns immediately and leaves the primary channel
allocated.
Unwind the primary mailbox channel before returning the error so probe
deferral or other setup failures do not leave the channel busy for later
probe attempts. |
| In the Linux kernel, the following vulnerability has been resolved:
cxl/mbox: Break poison list loop on an empty payload
A device that returns count == 0 with CXL_POISON_FLAG_MORE set on every
iteration never advances nr_records, so the max_errors guard never
trips and the do/while loops forever while holding poison.mutex. That
hangs the sysfs-triggered scan thread and blocks all subsequent poison
operations on the device. The existing "Protect against an uncleared
_FLAG_MORE" guard was intended to bound a misbehaving device but does
not cover the count == 0 case.
Stop the loop on an empty payload so a malfunctioning or malicious
device cannot wedge the poison scan. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/hfi1: Preserve unit 0 on allocation failure
hfi1_free_devdata() assumes that the device was inserted into the unit
table and unconditionally erases dd->unit. If xa_alloc_irq() fails, the
zero-initialized unit remains zero, so full cleanup can remove an
unrelated device from index 0.
Release only the rdmavt allocation and return immediately while the unit
table has not acquired the device. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Reject arena frees below the arena base
bpf_arena_free_pages() accepts scalar arena addresses. The runtime
masks the address to the low 32 bits and reconstructs a full user
address from the arena base before returning the range to the arena
free tree.
When the scalar value is below the low 32 bits of the arena base,
full_uaddr falls below user_vm_start. The existing upper-end clipping
then turns this into an out-of-range free-tree offset. A later
allocation can reuse that offset and return an address below the arena
mapping.
Reject such frees before computing the clipped range. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/msm: Only fini scheduler after successful init
msm_ringbuffer_new() destroys a partially initialized ring through
msm_ringbuffer_destroy() when an allocation or scheduler setup step
fails.
If drm_sched_init() fails before it finishes initializing the scheduler,
the failure path still calls drm_sched_fini(). That teardown path assumes
the scheduler work items, lists, and workqueue state were initialized.
Track successful scheduler initialization and call drm_sched_fini() only
after drm_sched_init() returned 0.
This issue was found by a static analysis checker and confirmed by
manual source review.
Patchwork: https://patchwork.freedesktop.org/patch/738905/ |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/bnxt_re: Clear VM_MAYWRITE on DBR/toggle page mmap
bnxt_re_mmap() rejects VM_WRITE for the DBR_PAGE and TOGGLE_PAGE mmap
flags, but a read-only mapping can still retain VM_MAYWRITE. nd later
be upgraded with mprotect(PROT_WRITE). This can bypass the write check
that only runs at mmap time.
Clear VM_MAYWRITE before vm_insert_page() in the shared DBR/toggle-page
branch, matching the existing policy that userspace writes are not
expected for these pages. |
| In the Linux kernel, the following vulnerability has been resolved:
dax/fsdev: clear vmemmap_shift when binding static pgmap
Clear pgmap->vmemmap_shift for static DAX devices. When rebinding a static
device from device_dax (which may set vmemmap_shift based on alignment) to
fsdev_dax, the stale vmemmap_shift persists on the shared pgmap. Explicitly
zero it before devm_memremap_pages() so the vmemmap is built for order-0
folios as fsdev requires. |
