| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix memory leak in ath12k_wifi7_dp_rx_h_verify_tkip_mic()
In ath12k_wifi7_dp_rx_h_verify_tkip_mic(), the call to
ath12k_dp_rx_check_nwifi_hdr_len_valid() may return false when the
NWIFI header length is invalid, causing the function to abort early with
-EINVAL.
When this happens, the error propagates to
ath12k_wifi7_dp_rx_h_defrag(), which clears first_frag by setting it
to NULL. As a result, the corresponding MSDU is no longer referenced
by the defragmentation path and is never freed.
This leads to a memory leak for the affected MSDU on this error path.
Proper cleanup is required to ensure the MSDU is released when header
validation fails during TKIP MIC verification.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00302-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.115823.3 |
| In the Linux kernel, the following vulnerability has been resolved:
gpu: host1x: Allow entries in BO caches to be freed
When a buffer object is pinned via host1x_bo_pin() with a cache, the
resulting mapping is kept in the cache so it can be reused on subsequent
pins. Each mapping held a reference to the underlying host1x_bo (taken
in tegra_bo_pin / gather_bo_pin), so as long as a mapping was cached,
the bo itself could not be freed.
However, the only way to remove the cached mapping was through the free
path of the buffer object. This meant that if a bo got cached, it could
never get freed again.
Resolve the circularity by holding a weak reference to the bo from the
cache side. This is done by having the .pin callbacks not bump the bo's
refcount -- instead the common Host1x bo code does so, except for the
cache reference.
Also move the remove-cache-mapping-on-free code into a common function
inside Host1x code. This is only called from the TegraDRM GEM buffers
since those are the only ones that can be cached at the moment. |
| @fastify/multipart is a multipart form-data parser for Fastify. In versions from 5.3.0 up to but not including 10.1.1, when the busboy fileSize limit truncates a file part, the plugin clears its internal current-file reference while the underlying stream is still open. If the client then aborts the connection before sending the terminating boundary, the abort cleanup finds no stream to destroy, so saveRequestFiles() never settles, the request handler hangs, and the temporary file already written to disk is never cleaned up. An unauthenticated client can repeat this to permanently leak temporary files and suspended handler executions, leading to disk and event-loop exhaustion. The issue is fixed in @fastify/multipart 10.1.1. Users should upgrade to 10.1.1. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7921: fix resource leak in probe error path
When pcim_iomap_region() or devm_kmemdup() fail, the code returns
directly without cleaning up previously allocated resources:
- mt76_device allocated by mt76_alloc_device()
- pci irq vectors allocated by pci_alloc_irq_vectors()
Fix this by jumping to the existing error cleanup path instead of
returning directly. |
| In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: call _ntfs_bad_inode() when failing to rename
It is safe to call _ntfs_bad_inode on live inodes since:
commit 519b078998ce ("fs/ntfs3: Exclude call make_bad_inode for live nodes.")
The WARN_ON was added when it wasn't safe by:
commit d99208b91933 ("fs/ntfs3: cancle set bad inode after removing name fails")
Replace the WARN_ON with a call to _ntfs_bad_inode() to prevent further
operations on the inconsistent inode. |
| In the Linux kernel, the following vulnerability has been resolved:
NFSD: Handle layout stid in nfsd4_drop_revoked_stid()
nfsd4_drop_revoked_stid() has no SC_TYPE_LAYOUT case, so when a
client sends FREE_STATEID for an admin-revoked layout stid, the
default branch releases cl_lock and returns without unhashing or
releasing the stid. The stid remains in the IDR and on the
per-client list until the client is destroyed.
Remove the layout stid from the per-client list and call
nfs4_put_stid() to drop the creation reference. When the
refcount reaches zero, nfsd4_free_layout_stateid() handles the
remaining cleanup: cancelling the fence worker, removing from
the per-file list, and freeing the slab object. |
| In the Linux kernel, the following vulnerability has been resolved:
md/raid10: fix writes_pending leak on write request failures
raid10_make_request() acquires a writes_pending reference with
md_write_start() before dispatching write requests. Several failure
paths in raid10_write_request() complete the bio and return without
reaching the normal write completion path, causing the corresponding
md_write_end() to be skipped.
Make raid10_write_request() return a status indicating whether the write
request was successfully queued. This allows raid10_make_request() to
release the writes_pending reference with md_write_end() when a write
request fails. |
| In the Linux kernel, the following vulnerability has been resolved:
octeontx2-pf: Fix leak of SQ timestamp buffer on teardown
The send-queue timestamp ring is allocated with qmem_alloc() when
timestamping is used, but otx2_free_sq_res() never freed sq->timestamps,
leaking that memory across ifdown and device removal. Add the missing
qmem_free() alongside the other SQ companion buffers. |
| In the Linux kernel, the following vulnerability has been resolved:
apparmor: release exe file resources on path failure
get_current_exe_path() takes both an exe_file reference and a path
reference before resolving the path name. If aa_path_name() failed, it
returned immediately and leaked both references.
Route the failure through the common cleanup path so fput() and path_put()
always run after the references are acquired. |
| In the Linux kernel, the following vulnerability has been resolved:
apparmor: fix refcount leak when updating the sk_ctx
Currently update_sk_ctx() transfers the plabel reference, unfortunately
it is also unconditionally put in the caller. Ideally we would make
the caller conditionally put the reference based on whether it was
transferred but for now just fix the bug by getting a reference. |
| In the Linux kernel, the following vulnerability has been resolved:
iomap: release pages on atomic dio size mismatch
If bio_iov_iter_get_pages() or the bounce helper succeeds but builds a
short bio, the REQ_ATOMIC size check rejects it before submission. The
old error path only dropped the bio reference, leaving any pages already
attached to the bio unreleased.
Release or unbounce the pages before falling through to out_put_bio on
this error path.

| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix insn_aux_data leak on verifier err_free_env path
When bpf_check() allocates env->insn_aux_data successfully but later
fails to allocate env->succ, it jumps directly to err_free_env.
The existing vfree(env->insn_aux_data) sits before the err_free_env
label, so that direct jump bypasses it and leaks insn_aux_data.
Move vfree(env->insn_aux_data) into err_free_env so all early and late
exit paths release it consistently. |
| In the Linux kernel, the following vulnerability has been resolved:
net: mvneta: re-enable percpu interrupt on resume
On Marvell MPIC platforms (Armada 370/XP/38x), mvneta uses a percpu
IRQ disable/enable scheme for NAPI: the ISR (mvneta_percpu_isr) calls
disable_percpu_irq() to mask the MPIC per-CPU interrupt and schedules
NAPI poll, which calls enable_percpu_irq() on completion to unmask.
If suspend occurs while NAPI poll is pending (between
disable_percpu_irq in the ISR and enable_percpu_irq in poll
completion), the interrupt is never re-enabled:
1. mvneta_percpu_isr: disable_percpu_irq() + napi_schedule()
=> MPIC masked, percpu_enabled cpumask bit cleared
2. NAPI poll does not complete before suspend proceeds
(on PREEMPT_RT this is highly likely since softirqs run in
ksoftirqd which gets frozen; on non-RT it can happen when
softirq processing is deferred to ksoftirqd)
3. mvneta_stop_dev => napi_disable(): cancels the pending poll
without executing the completion path
4. suspend_device_irqs => IRQCHIP_MASK_ON_SUSPEND: masks MPIC
(already masked, but records IRQS_SUSPENDED)
5. Resume: mpic_resume checks irq_percpu_is_enabled() => false
(bit was cleared in step 1) => skips unmask
6. mvneta_start_dev only restores device-level INTR_NEW_MASK,
does not touch the MPIC per-CPU mask
Result: MPIC per-CPU interrupt stays masked permanently. The NIC
generates interrupts (INTR_NEW_CAUSE != 0) but the CPU never
receives them, causing complete loss of network connectivity.
Fix by calling on_each_cpu(mvneta_percpu_enable) in the resume path
to unconditionally unmask the MPIC per-CPU interrupt regardless of
pre-suspend state. |
| In the Linux kernel, the following vulnerability has been resolved:
sctp: fix err_chunk memory leaks in INIT handling
When sctp_verify_init() encounters unrecognized parameters, it allocates an
err_chunk to report them. However, this chunk is leaked in several code
paths:
1. In sctp_sf_do_5_1B_init(), if security_sctp_assoc_request() fails after
sctp_verify_init() has populated err_chunk, the function returns
immediately without freeing it.
2. In sctp_sf_do_unexpected_init(), the same leak occurs on the
security_sctp_assoc_request() failure path.
3. In sctp_sf_do_unexpected_init(), on the success path after copying
unrecognized parameters to the INIT-ACK, the function returns without
freeing err_chunk, unlike sctp_sf_do_5_1B_init() which properly frees
it.
Fix all three leaks by adding sctp_chunk_free(err_chunk) calls before
returning in the error paths and on the success path in
sctp_sf_do_unexpected_init(). |
| In the Linux kernel, the following vulnerability has been resolved:
fbdev: efifb: fix memory leak in efifb_probe()
Since commit 73ce73c30ba9 ("fbdev: Transfer video= option strings to
caller; clarify ownership") the string returned from fb_get_options()
is expected to be freed by the caller, but the string is not freed in
efifb_probe(). Fix that by freeing the option string after setup. |
| In the Linux kernel, the following vulnerability has been resolved:
cachefiles: Fix double unlock in nomem_d_alloc error path
When start_creating() fails and returns -ENOMEM, it has already
released the parent directory lock in __start_dirop():
static struct dentry *__start_dirop(...)
{
...
inode_lock_nested(dir, I_MUTEX_PARENT);
dentry = lookup_one_qstr_excl(name, parent, lookup_flags);
if (IS_ERR(dentry))
inode_unlock(dir); <-- Lock released on error
return dentry;
}
However, the nomem_d_alloc error path in cachefiles_get_directory()
unconditionally calls inode_unlock(d_inode(dir)) again, causing a
double unlock that corrupts the rwsem state.
This is a leftover from commit 7ab96df840e60 which replaced manual
locking with start_creating() but failed to update the nomem_d_alloc
path (while correctly updating mkdir_error and lookup_error paths). |
| Uncontrolled resource consumption vulnerability in Apache Struts. An application that exposes an endpoint collecting Content Security Policy violation reports reads the submitted report into memory without bounding how much it will accept, so a single request can exhaust the heap and deny service to other users. Such endpoints are ordinarily reachable without authentication. The core distribution maps no such endpoint by default; applications that do not collect violation reports are not affected.
This issue affects Apache Struts: from 6.0.0 through 6.10.0, from 7.0.0 through 7.2.1.
Users are recommended to upgrade to version 6.11.0 or 7.3.0, which fixes the issue. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv4: igmp: Fix potential memory leaks in igmp_mod_timer() and igmp_stop_timer()
When a timer is deleted and not re-armed in igmp_mod_timer(), or stopped
in igmp_stop_timer(), the code currently decrements the reference counter
of the multicast list entry @im using refcount_dec(&im->refcnt).
However, both functions can be called from the RCU reader path:
- igmp_mod_timer() via igmp_heard_query() -> for_each_pmc_rcu()
- igmp_stop_timer() via igmp_rcv() -> igmp_heard_report()
If the group im was concurrently removed from the list by ip_mc_dec_group(),
its reference count might have already been decremented to 1.
In this case, timer_delete() succeeds, and refcount_dec() decrements
the refcount from 1 to 0. Since refcount_dec() does not free the object
when it hits 0 (unlike ip_ma_put()), the im structure is leaked.
Fix this by using ip_ma_put(im) instead of refcount_dec(&im->refcnt),
and deferring the put until after the spinlock is released. |
| In the Linux kernel, the following vulnerability has been resolved:
gpio: mvebu: free generic chips on unbind
irq_alloc_domain_generic_chips() allocates generic chip data that must
be freed via irq_domain_remove_generic_chips(). The devres action
mvebu_gpio_remove_irq_domain() only called irq_domain_remove(), which
only frees the generic chips if IRQ_DOMAIN_FLAG_DESTROY_GC is set.
Call irq_domain_remove_generic_chips() explicitly before
irq_domain_remove() instead. |
| In the Linux kernel, the following vulnerability has been resolved:
fbdev: nvidia: fix potential memory leak in nvidiafb_probe()
In nvidiafb_probe(), the memory allocated for modelist in
nvidia_set_fbinfo() is not freed in the subsequent error paths.
Fix that by calling fb_destroy_modelist(). |
