| In the Linux kernel, the following vulnerability has been resolved:
greybus: audio: bound the topology section sizes against the fetched size
gb_audio_gb_get_topology() fetches a topology blob of a module-supplied
size, and gbaudio_tplg_parse_data() then walks it by adding the
module-supplied size_dais, size_controls and size_widgets fields to
form the control, widget and route section offsets. Those le32 sizes
are never checked against the fetched blob, so a module reporting a
small topology size but large section sizes makes the offsets point
past the allocation, and parsing reads out of bounds.
Reject a topology whose section sizes do not fit within the fetched
size before it is parsed. |
| In the Linux kernel, the following vulnerability has been resolved:
ocfs2: do not use make_bad_inode() in ocfs2_read_inode_block_full()
This reverts commit 58b6fcd2ab34 ("ocfs2: mark inode bad upon validation
failure during read").
Since 'make_bad_inode()' resets inode type to S_IFREG, doing this for
directory inode during active VFS lookup is likely to confuse the latter,
including VFS_BUG_ON_INODE() triggered in this case. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: skip extra isize expansion during mount to prevent deadlock
ext4_try_to_expand_extra_isize() is called from __ext4_mark_inode_dirty()
while holding an active jbd2 handle. During mount (!SB_ACTIVE), the
expand path may move xattrs to external blocks and release ea_inodes via
iput(). When !SB_ACTIVE, iput() calls write_inode_now() which acquires
s_writepages_rwsem, creating a circular lock dependency:
s_writepages_rwsem --> jbd2_handle --> xattr_sem --> s_writepages_rwsem
This can be triggered via:
ext4_process_orphan() -> ext4_truncate() -> ext4_mark_inode_dirty()
-> ext4_try_to_expand_extra_isize()
or:
ext4_evict_inode() -> ext4_mark_inode_dirty()
-> ext4_try_to_expand_extra_isize()
Skip expansion when !SB_ACTIVE. This is a minor loss of functionality
(extra isize won't grow for these inodes during mount), which e2fsck
can resolve later if needed. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/bnxt_re: Validate udata before executing commands
The destroy callbacks currently zero the udata output after tearing down
driver resources. If the userspace access fails, uverbs preserves the
uobject and allows the destroy callback to run again, even though the
driver resource has already been freed.
Call ib_no_udata_io() before teardown so udata failures are detected
while the resource is still intact, then return success after teardown
completes.
As part of this change, move ib_respond_empty_udata() to the start of
the create and modify flows. While this is not strictly required for
general create flows, as the core layer unwinds uobjects on failure, it
is necessary for create AH. In _rdma_create_ah(), the HW object is
otherwise leaked. |
| In the Linux kernel, the following vulnerability has been resolved:
apparmor: policy_int make sure list heads are initialized before fail path
If profile create fails before policy_init is complete the list heads
are not properly initialized causing profile_free() sanity checks to
trigger the following splat.

octeontx2-af: fix out-of-bounds read setting MSI-X irq affinity
rvu_register_interrupts() walks every MSI-X vector and uses strstr()
to match "Mbox" or "FLR" in irq_name before pinning those interrupts
to CPU 0. irq_name is a per-vector NAME_SIZE buffer, but not every
slot is populated before this loop runs. strstr() keeps scanning until
it finds a NUL terminator, so an uninitialized slot can trigger a KASAN
slab-out-of-bounds read at boot when debug options are enabled.
Use strnstr() with NAME_SIZE to bound the search within each vector's
name buffer. |
| In the Linux kernel, the following vulnerability has been resolved:
phy: renesas: phy-rcar-gen3-usb2: Fix devm action registration for disabled VBUS regulator
devm_regulator_get_exclusive() initialises the regulator with
enable_count = 1, requiring the consumer to disable it before release.
The devm disable action was previously only registered when the caller
explicitly requested enable, so when the regulator was left in its initial
enabled state without an explicit enable call, the cleanup path skipped
decrementing enable_count, triggering a WARN_ON during regulator
release on device removal.
Fix this by always registering the devm disable action based on the actual
enabled state via regulator_is_enabled(), regardless of whether the
caller requested an explicit enable. This covers both the explicitly
enabled case and the initial state set by devm_regulator_get_exclusive(). |
| In the Linux kernel, the following vulnerability has been resolved:
LoongArch: Add DIRECT_MAP_PHYSMEM_END definition
get_free_mem_region() and mhp_get_pluggable_range() bound their search
to DIRECT_MAP_PHYSMEM_END. LoongArch does not define it, so the fallback
in include/linux/mm.h applies: under CONFIG_SPARSEMEM_VMEMMAP it is
(1ULL << MAX_PHYSMEM_BITS) - 1, a compile-time constant that does not
adapt to the CPU's physical address space bits (cpu_pabits, probed from
CPUCFG1).
The vmemmap window only covers physical space below 2^(cpu_pabits+1)
(i.e. VMEMMAP_SIZE), so on CPUs with fewer physical address bits than
MAX_PHYSMEM_BITS the fallback allows get_free_mem_region() to return
a ZONE_DEVICE region outside the vmemmap window; vmemmap_populate() then
wraps the memmap range around and maps it into low memory, silently
corrupting the page tables. The same search also picked the top-of-
address-space region that crashed memmap_init_zone_device() with amdkfd
on Loongson-3C6000 in 6.16 [1]; the commit 2969b42c8f99 ("LoongArch/mm:
align vmemmap to maximal folio size") keeps that region in bounds on
current Loongson-3C6000 configs, but CPUs with smaller cpu_pabits (e.g.
the Loongson-2K series) are still affected.
Define DIRECT_MAP_PHYSMEM_END as the vmemmap-covered physical range,
(1ULL << (cpu_pabits + 1)) - 1, capped at (1ULL << MAX_PHYSMEM_BITS) - 1
under CONFIG_SPARSEMEM, similar to the commit f3336b48cf9d ("riscv: mm:
Define DIRECT_MAP_PHYSMEM_END").

BTRFS warning (device sdd): unable to release extent buffer 365985792 owner 3 gen 17 refs 3 flags 0x5
[CAUSE]
In that invalidate_and_check_btree_folios() we wait for the eb to finish
its read, then check if it's only held by us and the btree inode.
If not, then do a warning as it may be still held, and could cause
problems.
But there is a small window where the check can lead to false alerts:
Thread A (Read endio) | Thread B (Unmount)
----------------------------------+-------------------------------------
end_bbio_meta_read() |
| The eb has one extra ref held |
| by the reader, and has |
| EXTENT_BUFFER_READING flag set | invalidate_and_check_btree_folios()
| | |
|- clear_extent_buffer_reading() | |
| | |- wait_on_bit_io();
| | | The EXTENT_BUFFER_READING flag is
| | | cleared
| | |- if (refcount_read(eb->refs) > 2)
| | The eb is held by the read, us
| | and btree inode, thus it
| | will trigger the warning
|- free_extent_buffer() |
[FIX]
Introduce a helper, free_extent_buffer_clear_reading().
If the new parameter, @clear_reading, is set, we will hold the spinlock
at the beginning of free_extent_buffer_clear_reading() to make sure the
EXTENT_BUFFER_READING flag is cleared inside the same critical section
of decreasing refs.
Now free_extent_buffer() will just call
free_extent_buffer_clear_reading() with @clear_reading set to false, so
no behavior change.
But for end_bbio_meta_read(), it will not clear_extent_buffer_reading()
directly, but pass @clear_reading as true.
Then inside invalidate_and_check_btree_folios(), hold the refs_lock
before reading refs.
So that we eliminate the race window completely. |
| In the Linux kernel, the following vulnerability has been resolved:
arm64: mm: Fix the lockless page-table walk in show_pte()
show_pte() walks page tables locklessly and can run with interrupts
enabled. A concurrent teardown can free a table page while it is being
walked. It can also clear a parent entry after show_pte() checked it; the
regular pXd_offset() helpers then reread the cleared entry and can derive a
bogus lower-level pointer and fault again.
Use the lockless offset helpers with the saved parent entries, as
gup_fast() does, and pass the saved PMD to pte_offset_map().
For task page tables, arm64 selects MMU_GATHER_RCU_TABLE_FREE. Disable
local interrupts around the walk to hold off RCU-deferred table frees and
block the tlb_remove_table_sync_one() IPI until the walk is finished.
Place the IRQ guard after the header print. This does not make the output a
consistent snapshot, but prevents the task page-table walk from
dereferencing a released table page or deriving a pointer from a different
parent value. |
| In the Linux kernel, the following vulnerability has been resolved:
signal: avoid shared siginfo namespace rewrites
send_signal_locked() rewrites sender ids for the target namespace. Group
sends reuse the same siginfo, so one recipient can affect the next.
Copy the siginfo before changing it. |

| In the Linux kernel, the following vulnerability has been resolved:
ext4: fix buffer_head leak in ext4_init_orphan_info
ext4_init_orphan_info() reads orphan file blocks with ext4_bread()
and stores the returned buffer_head in oi->of_binfo[i].ob_bh.
If ext4_bread() succeeds but the orphan block magic or checksum
validation fails, the function jumps to out_free. However, the old
out_free loop starts releasing buffers from i - 1, so the current
buffer_head at index i is skipped.
This leaks the buffer_head reference obtained by ext4_bread() on the
bad magic and bad checksum error paths.
Fix this by tracking the number of successfully read buffer_heads and
releasing exactly those buffer_heads on the error path. |
| In the Linux kernel, the following vulnerability has been resolved:
irqchip/renesas-irqc: Fix generic interrupt chip leak on remove
The driver allocates domain generic chips probe. However, on driver
removal, the generic chips are not automatically freed when the interrupt
domain is removed because the domain flags do not include
IRQ_DOMAIN_FLAG_DESTROY_GC.
This causes both the domain generic chips structure and the associated
generic chips to be leaked. Additionally, the generic chips remain on the
global list and may later be accessed by generic interrupt chip suspend,
resume, or shutdown callbacks after the driver has been removed,
potentially resulting in a use-after-free and kernel crash.
Fix the resource leak by setting IRQ_DOMAIN_FLAG_DESTROY_GC on the
interrupt domain; this lets the interrupt domain core automatically
release all generic chips when irq_domain_remove() is invoked, removing
the need for manual cleanup calls in error paths and remove callback. |
| In the Linux kernel, the following vulnerability has been resolved:
platform/x86: asus-wmi: fix resource leaks on probe failure
During driver initialization in asus_wmi_add(), various subsystems are
registered sequentially. However, the error path labels are out of order
relative to the registration sequence.
Specifically:
1. If asus_wmi_custom_fan_curve_init() fails, the driver jumps to
fail_custom_fan_curve. Because this label is placed below fail_sysfs,
it bypasses the cleanup calls for the input device and sysfs groups,
which were successfully registered before, leaking those resources.
2. If asus_screenpad_init() fails, the driver jumps to fail_screenpad.
Because fail_screenpad is placed below fail_backlight, it bypasses the
cleanup calls for backlight and rfkill, leaking those resources.
Fix these resource leaks by reordering the error path labels in
asus_wmi_add() to match the exact reverse order of the resource
allocations. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: fix dc_lock leak on GPU reset error paths
On GPU reset, dm_suspend() takes dc_lock and leaves it for dm_resume()
to drop. If amdgpu_dm_commit_zero_streams() or dm_dmub_hw_init() fails,
the function returns with the lock still held. The matching resume path
is then skipped, so every later dc_lock take hangs.
Release the cached DC state and unlock before returning the error. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix BSG job leak on validate flash image error path
qla28xx_validate_flash_image() returns QLA_SUCCESS (0) unconditionally,
telling the FC BSG transport (fc_bsg_host_dispatch()) that the driver
owns and will complete the request. But bsg_job_done() is guarded by "if
(!rval)", so on the error path (rval == -EINVAL) neither the driver nor
the transport completes the job. The request dangles until it times out,
leaking block layer resources.
Commit c2c68225b145 ("scsi: qla2xxx: Fix bsg_done() causing double
free") added the "if (!rval)" guard to a batch of BSG handlers. That is
correct for handlers that also return the error code (the transport then
completes the job once via fail_host_msg), but this function returns
QLA_SUCCESS unconditionally, so the guard turned a correct single
completion into a leak.
Always call bsg_job_done(): bsg_reply->result is DID_OK and the error is
reported in vendor_rsp[0], and since the function returns 0 the
transport will not complete the job a second time. |
| In the Linux kernel, the following vulnerability has been resolved:
media: intel/ipu6: fix async notifier cleanup leak on parse error
isys_notifier_init() calls v4l2_async_nf_init() and then adds fwnode
remote subdevs in a loop with v4l2_async_nf_add_fwnode_remote(). If an
endpoint parse or add fails partway through the loop, it jumps to
err_parse and returns without calling v4l2_async_nf_cleanup(), leaking
every v4l2_async_connection already added to the notifier's waiting
list.
The register-failure path just below already cleans up correctly, and
the caller only tears the notifier down (isys_notifier_cleanup()) once
isys_notifier_init() has returned success. Clean up the notifier on the
parse error path too. |
