CVSS v3.1 |
| Race condition in WebAppInstalls in Google Chrome on on Android prior to 152.0.7977.65 allowed a remote attacker leveraging social engineering to bypass web origin policy via a co-installed app. (Chromium security severity: High) |
| libjpeg-turbo 3.2.0 contains an integer division-by-zero vulnerability in the PNG loader. When processing a valid indexed-color PNG image with a non-gray palette through tj3LoadImage12() or tj3LoadImage16() using the default pixel format, the application may trigger a division-by-zero in alloc_sarray(), causing a SIGFPE and denial of service. |
| Race condition in Core in Google Chrome on on Windows prior to 152.0.7977.65 allowed a remote attacker leveraging social engineering to bypass web origin policy via a crafted HTML page. (Chromium security severity: Low) |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: ipc4-topology: Refresh copier IPC payload before widget setup
The ipc_config_data buffer for copier widgets is built once during
ipc_prepare (called from sof_pcm_setup_connected_widgets) and cached
for reuse. For host copiers this buffer contains the copier_data with
gtw_cfg.node_id (host DMA ID). For DAI copiers it additionally includes
a dma_config_tlv trailer with stream_id and dma_channel_id for HDA link
DMA.
On suspend/resume, both host and link DMA streams are released and
re-allocated with potentially different stream tags. The underlying
copier_data and dma_config_tlv structures are correctly updated by
host_config and sdw_hda_dai_hw_params respectively. However, since the
widget list (spcm->stream[].list) persists across suspend,
sof_pcm_hw_params skips sof_pcm_setup_connected_widgets and ipc_prepare
never runs again to rebuild ipc_config_data. The stale cached payload
is then sent to firmware with boot-time DMA channel assignments, causing
DMA channel conflicts that lead to firmware errors and crashes.
Fix this by refreshing copier_data and dma_config_tlv portions of
ipc_config_data in sof_ipc4_widget_setup right before the IPC message
is sent. This ensures the payload always reflects the current DMA state
regardless of whether ipc_prepare ran.
For DAI copiers, the gtw_cfg.config_length in copier_data is temporarily
inflated to include the TLV size (matching the ipc_config_data layout)
before copying, then restored, mirroring what
sof_ipc4_prepare_copier_module does when first building the buffer. |
| An issue in Vanderbilt Industries, Acre Security SPC5300.000 Main Board v.3.14.1 allows a physically proximate attacker to cause a denial of service via spoofed TCP FIN packets without validating the sequence or acknowledgment numbers. |
| In the Linux kernel, the following vulnerability has been resolved:
af_unix: Unlink scc_entry in unix_del_edge().
Kyle Zeng reported that GC could free a dead SCC partially.
The scenario is as follows:
1) Create two SCCs:
X -. A <-> B
^--'
2) Run the following concurrently:
2-1) send() sk-B to sk-B from sk-X
2-2) close() both A and B
At 2-1), there is a small window where unix_add_edges()
publishes a new edge (B <-> B) to GC but its skb is not queued
by skb_queue_tail().
If 2-2) completes before skb_queue_tail() and GC is triggered,
it judges A <-> B as dead, but B is not freed because GC cannot
collect the not-yet-queued skb holding the B <-> B edge.
X -. A <-> B -. This edge is visible
^--' ^..' but skb is not
This itself is not a problem since the next GC run will judge
B as dead as well and free it finally.
X -. A <.> B -.
^--' ^--'
However, X's SCC forces the next GC to call unix_walk_scc_fast(),
and it iterates over A through B's scc_entry.
Let's unlink scc_entry before freeing the vertex in unix_del_edge(). |
| In the Linux kernel, the following vulnerability has been resolved:
Input: byd - synchronize timer deletion before freeing private data
byd_disconnect() uses timer_delete() before freeing the driver's private
data. This does not wait for a running byd_clear_touch() callback, which
dereferences the private data and its psmouse pointer. A callback racing
with disconnect can therefore access the private data after it has been
freed. The timer can also still be re-armed by byd_process_byte() while
the disconnect is in progress.
Use timer_shutdown_sync() before freeing the private data: it waits for
a running callback and turns any later re-arm attempt into a no-op. |
| In the Linux kernel, the following vulnerability has been resolved:
net: enetc: fix potential divide-by-zero when num_vsi is zero
For i.MX94 series, all the standalone ENETCs do not support SR-IOV, so
pf->caps.num_vsi is zero. This leads to a divide-by-zero in
enetc4_default_rings_allocation() when distributing rings among PF and
VFs.
Division by zero is undefined behavior in C. On ARM64, the UDIV/SDIV
instructions silently return zero rather than raising an exception, so
the issue does not cause a visible crash. However, relying on this
behavior is incorrect and poses a cross-platform compatibility risk.
Add an explicit check for num_vsi == 0 and return early after the PF's
rings have been configured. |
| In the Linux kernel, the following vulnerability has been resolved:
ACPI: processor_idle: Mark LPI enter functions as __cpuidle
When function tracing or Kprobes is enabled, entering an ACPI Low
Power Idle (LPI) state triggers the following RCU splat:
RCU not on for: acpi_idle_lpi_enter+0x4/0xd8
WARNING: CPU: 8 PID: 0 at include/linux/trace_recursion.h:162 function_trace_call+0x1e8/0x228
The acpi_idle_lpi_enter() function is invoked within the cpuidle
path after RCU has already been disabled for the current local CPU.
Consequently, ftrace's function_trace_call() expects RCU to be
actively watching before recording trace data, emitting a warning
if it is not.
Fix this by annotating acpi_idle_lpi_enter(), the generic __weak
stub, and the RISC-V implementation of acpi_processor_ffh_lpi_enter()
with __cpuidle. This moves these functions into the '.cpuidle.text'
section, implicitly disabling ftrace instrumentation (notrace) along
this sensitive path and preventing trace-induced RCU warnings during
idle entry. |
| In the Linux kernel, the following vulnerability has been resolved:
mm: mglru: fix stale batch updates after memcg reparenting
The mglru page table walker batches per-generation size deltas in
walk->nr_pages while walking page tables without holding the lruvec lock.
The reset_batch_size() later folds those deltas into walk->lruvec under
the lruvec lock.
The page table walker can run concurrently with the memcg reparenting path
as follows:
CPU0 CPU1
==== ====
walk_mm
--> walk_page_range
--> update_batch_size
--> walk->nr_pages += delta
mem_cgroup_css_offline
--> memcg_reparent_objcgs
--> lock lruvec
lru_gen_reparent_memcg
--> reparent child folios to parent
unlock lruvec
lock lruvec
reset_batch_size
--> child lrugen->nr_pages += delta
This will trigger the following warning in lru_gen_exit_memcg():
VM_WARN_ON_ONCE(memchr_inv(lruvec->lrugen.nr_pages, 0,
sizeof(lruvec->lrugen.nr_pages)));
And the user-visible impact of underestimated nr_pages in MGLRU was
premature OOMs because MGLRU does not try to reclaim memory when nr_pages
reaches zero, but there are still more pages.
To fix it, make reset_batch_size() check CSS_DYING under RCU before
flushing the pending batch. A non-dying memcg keeps the original lruvec
stable against RCU-delayed offlining; a dying memcg redirects the deltas
to the first non-dying ancestor. |
| In the Linux kernel, the following vulnerability has been resolved:
s390/vfio_ccw: Selectively expand io_mutex
The io_mutex was defined to serialize the io_regions, but then has
also sort of been associated with the I/O themselves because of
the close relationship they share.
With the handful of races that are possible, the choices are either to:
A) expand the scope of io_mutex to close these remaining windows, or
B) reduce the scope of io_mutex to just io_region, and introduce a new
lock mechanism for the remaining I/O resources
This patch implements A, since B brings with it a lot more interactions
that would need to be tracked and kept in a correct hierarchy. It also
takes advantage of the workqueue element for cp_free() that now gets
called out of fsm_notoper(), which could be invoked out of an interrupt
context and thus cannot acquire a mutex itself. |
| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: LAG, MPESW, Fix missing complete() on devcom error
mlx5_mpesw_work() returned without calling complete() when
mlx5_lag_get_devcom_comp() returned NULL. A caller that queued the
work and waited on mpesww->comp would block indefinitely.
Funnel the early-return path through a new "complete" label so the
waiter is always woken. |
| In the Linux kernel, the following vulnerability has been resolved:
s390/vfio_ccw: Ensure first IDAW remains constant
The first IDAW in a list does not need to be on a 2K/4K boundary
like all others, and so is read separately to accurately calculate
the size of the buffer needed to read the full IDAL.
Verify that the address found in the first IDAW is unchanged between
reads, to ensure a consistent set of IDAWs being worked with. |
| In the Linux kernel, the following vulnerability has been resolved:
mmc: vub300: defer reset until cmd_mutex is unlocked
vub300_cmndwork_thread() holds cmd_mutex while it sends a command and
waits for the command response. If the response wait times out,
__vub300_command_response() kills the command URBs and then synchronously
resets the USB device through usb_reset_device().
That reset path re-enters the driver through vub300_pre_reset(), which
also takes cmd_mutex. The worker therefore tries to acquire the same
mutex recursively while it is still holding it from the command path.
This issue was found by our static analysis tool and then manually
reviewed against the current tree.
The grounded PoC kept the real worker and timeout/reset carrier:
vub300_cmndwork_thread()
__vub300_command_response()
usb_lock_device_for_reset()
usb_reset_device()
vub300_pre_reset()
Lockdep reported the same-task recursive acquisition on cmd_mutex:
WARNING: possible recursive locking detected
... (&test_vub300.cmd_mutex) ... at: usb_reset_device... [vuln_msv]
... (&test_vub300.cmd_mutex) ... at: vub300_cmndwork_thread+0x12/0x20 [vuln_msv]
Workqueue: vub300_cmd_wq vub300_cmndwork_thread [vuln_msv]
*** DEADLOCK ***
Return a flag from __vub300_command_response() when the timeout path needs
a device reset, then perform the reset after vub300_cmndwork_thread() has
cleared the in-flight command state and dropped cmd_mutex. The reset is
still attempted before mmc_request_done(), preserving the existing request
completion ordering while avoiding the recursive lock. |
| SvelteKit versions from 2.38.0 before 2.60.1 contain a race condition in query.batch that allows concurrent requests from different users to merge under a single request context. Attackers can exploit specific timing conditions to access sensitive data from other users' concurrent requests. |
| filebrowser from version 2.24.0 contains a race condition in the TUS upload handler that allows authenticated users to write past the declared Upload-Length by sending concurrent PATCH requests. Attackers can send multiple simultaneous PATCH requests at the same offset to bypass length validation, resulting in files that exceed their declared size and triggering completion hooks for oversized uploads. |
| In the Linux kernel, the following vulnerability has been resolved:
s390/vfio_ccw: Cancel existing workqueues
The initialization of the io_work and crw_work workqueues begs the
question of whether they should be un-initialized. Add the corresponding
cleanup tags in _release_dev to ensure work isn't dispatched after
the private struct is free'd. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: ipset: fix refcount race between list:set GC and swap
__ip_set_put_byindex() resolved the index to a set pointer under RCU,
then took ip_set_ref_lock in __ip_set_put() to decrement set->ref.
ip_set_swap() holds that same lock while swapping both the ip_set_list
slots and the two sets' ref counters, so it can interleave between the
dereference and the lock acquisition, leaving the caller to decrement a
set whose reference already moved to the other index and hit
BUG_ON(set->ref == 0). list_set_gc() reaches this from timer softirq,
which the nfnl mutex does not serialize against swap: an expiring
list:set member calls list_set_del() -> ip_set_put_byindex() while
IPSET_CMD_SWAP runs on the referenced sets.
Resolve the index and decrement under ip_set_ref_lock, as ip_set_swap()
already does, keeping the refcount tied to the index rather than to a
stale set pointer.
