CVSS v3.1 |
| A flaw was found in GStreamer gst-plugins-good (avidemux). In gst_avi_demux_riff_parse_vprp(), the number of available gst_riff_vprp_video_field_desc entries is calculated by dividing the remaining buffer size by the attacker-controlled vprp->fields value, rather than by sizeof(gst_riff_vprp_video_field_desc). This can cause the parser to treat more field descriptors as available than fit in the input buffer, resulting in out-of-bounds reads. Processing a crafted AVI via playbin/decodebin can crash the application (denial of service). Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072). |
| A flaw was found in GStreamer gst-plugins-good (avidemux). When parsing FUJIFILM metadata in an AVI strd chunk, gst_avi_demux_parse_strd() decrements a remaining-length counter by fixed offsets (98 and 10 bytes) without verifying sufficient data remains. For crafted strd payloads of exactly 106 or 107 bytes, the counter underflows to a very large unsigned value, causing subsequent null-terminated string scanning to read far beyond the allocated heap buffer. Date-format normalization may also write beyond the buffer end. Confirmed impacts include heap out-of-bounds read, out-of-bounds write, heap information disclosure (adjacent data appearing in parsed metadata), and application crash/denial of service. The avidemux element is auto-plugged by playbin, decodebin, and gst-discoverer, so opening or previewing a crafted AVI is sufficient to trigger the issue. Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072). |
| Some Hikvision intercom products utilize an immutable factory value which should be obtained from local network or physical interaction with the device within their main card, which may allow attackers to forge a legitimate main card, thereby gaining the permission to issue cards. |
| A flaw was found in Quarkus HTTP security. An unauthenticated attacker can exploit a discrepancy in how paths are normalized between the security matcher and HTTP request dispatchers. This allows the attacker to craft a URL that the security matcher considers public, but which is then routed to a protected endpoint, leading to an authorization bypass and potential unauthorized access to sensitive information. |

mm/damon/core: avoid infinite kdamond_merge_regions() internal loop
Patch series "mm/damon: unurgent fixes for infinite loop, NULL de-ref and
races", v1.1.
Sashiko found a few issues in DAMON that could cause infinite loop, NULL
dereference and monitoring results degradation. The first two sounds
scary but the infinite loop happens only under unreasonable user setup.
The NULL dereference is only in a unit test. Monitoring results
degradation is trivial since it is only best-effort, and those happens
from only unlikely races. Still those are bugs that better to fix if
possible. Fix those.
This patch (of 6):
Due to online parameter update like events, the number of DAMON regions
could be higher than the user-set upper limit. kdamond_merge_regions()
repeats merge regions until the number meets the limit, while doubling the
merge threshold up to the theoretical maximum threshold. It is tried only
up to the theoretical maximum threshold because even the aggressive
merging can fail from reducing the number of regions under the
user-defined upper limit. For example, there could be many user-defined
non-contiguous regions that cannot be merged.
The threshold based loop break condition is evaluated by comparing the
threshold for the next merging try against the theoretical maximum
threshold. If max_thres is larger than UINT_MAX / 2, doubling the
threshold could make it overflow, and bypass the loop break condition. In
the case, if the number of regions cannot be reduced under the upper limit
like explained above, the loop will run infinitely.
Prevent the case by doing the break condition check before doubling the
threshold. Also, prevent the threshold exceeding the maximum threshold,
as it could overflow and apply the wrong merge threshold.
This issue is unlikely to occur in real world, since having the max_thres
higher than UINT_MAX / 2 require unrealistically large aggregation
intervals compared to the sampling interval. Also, it requires an
unrealistically large number of uncontiguous regions setup. Nonetheless,
the consequence is bad and the fix is simple.
The issue was discovered [1] by Sashiko. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau: unsubscribe the channel-kill event before the fence context
nouveau_channel_del() tears the fence context down first and only drops
the channel-kill subscription later, in the middle of the nvif object
teardown:
if (chan->fence)
nouveau_fence(chan->cli->drm)->context_del(chan);
...
nvif_object_dtor(&chan->vram);
nvif_event_dtor(&chan->kill);
The subscribed handler is nouveau_channel_killed(), which calls
nouveau_channel_kill() and from there nouveau_fence_context_kill() on
chan->fence. A kill event delivered in that window takes fctx->lock and
walks fctx->pending on a fence context that context_del() has already
freed.
Nothing reaches this below Fermi today, because the subscription is
gated on FERMI_CHANNEL_GPFIFO and nothing kills a channel there. On
Fermi and newer the window is real but narrow, since a kill has to land
exactly while the channel is being destroyed. That is reason enough on
its own, which is why this carries a Fixes: tag. The last patch in this
series subscribes Tesla channels as well; nothing kills those today, so
it does not widen the exposure now, but it is the groundwork for a
recovery path that would, and the ordering is better fixed before that
lands than alongside it.
Drop the subscription before anything it depends on is torn down. |

drm/pagemap: Fix folio allocation fallback and use-after-put
drm_pagemap_migrate_populate_ram_pfn() had two issues when populating
RAM PFNs with higher-order folios:
1. The higher-order vma_alloc_folio()/folio_alloc() calls did not pass
__GFP_NOWARN, so a THP allocation failure under memory pressure
would spam the kernel log, and there was no fallback path despite a
TODO comment stating one was needed. Add __GFP_NOWARN to the
higher-order allocation and, on failure, fall back to order-0
allocations for the entire range originally covered by the failed
higher-order allocation, leaving MIGRATE_PFN_COMPOUND unset for
those PFNs.
2. In the free_pages error path, order was computed via
folio_order(page_folio(page)) *after* put_page(page) had already
dropped the reference, resulting in a use-after-free/put when that
was the last reference on the page. Compute order before releasing
the page.
Introducing the fallback in 1. also requires the source page array
handed to ->copy_to_ram() to be built differently. Both callers only
populated the entry at the head of each source folio, relying on the
copy callback to derive the rest of the folio from the order recorded
in the matching drm_pagemap_addr. Once the destination has been demoted
to order-0 folios the drm_pagemap_addr entries are per-page, so a source
page is needed for every one of them; leaving them NULL makes the copy
callback stop after the first page and the remainder of the range is
never copied.
The source folio is only split later, by migrate_vma_pages() /
migrate_device_pages(), so its order cannot be used to detect the
demotion - test the destination for MIGRATE_PFN_COMPOUND instead. Factor
the array population out into drm_pagemap_migrate_populate_src_pages()
and use it from both drm_pagemap_evict_to_ram() and
__drm_pagemap_migrate_to_ram(). |

drm/amdkfd: guard against NULL restore_mqd in CRIU queue restore
Both create_queue_cpsch() and create_queue_nocpsch() unconditionally
call mqd_mgr->restore_mqd() when a CRIU restore is in progress
(qd != NULL), with no NULL guard. On any system where restore_mqd is
not implemented for the given queue type, a user holding
CAP_CHECKPOINT_RESTORE can trigger a kernel NULL pointer dereference
and panic the machine by issuing KFD_IOC_CRIU_OP_RESTORE with a
crafted queue restore object. Note that checkpoint_mqd is likewise
unimplemented on GFX12, so no legitimate CRIU image can reach this
path — only a hand-crafted restore payload.
Add a NULL guard for restore_mqd immediately after mqd_mgr is
resolved, unwinding via the existing error labels and returning
-EOPNOTSUPP if the callback is not implemented. This mirrors the
existing checkpoint_mqd guard in checkpoint_mqd(). |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Add TLB flush after MES queue eviction/suspension
MES (Micro Engine Scheduler) does not perform heavy-weight TLB
invalidation after unmapping queues, unlike HWS which does this
automatically. This causes a race condition where in-flight DMA
descriptors can access memory that has been unmapped, leading to page
faults and GPU queue hangs during SVM page migration.
The issue manifests as KFDSVMRangeTest.MultiThreadMigrationTest
failures on gfx1151 (Strix Point) with XNACK mode 1 enabled - the GPU
compute queue hangs with packets submitted but never consumed.
Add kfd_flush_tlb() calls after MES queue removal in two locations:
- evict_process_queues_cpsch(): after all queues removed during eviction
- suspend_queues(): after debug/criu queue suspension (with mem_fence barrier)
This ensures all in-flight memory accesses from unmapped queues are
flushed before memory is freed or migrated.

| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Reject non-SCSI SRB on status IOCB fast path
qla2x00_status_entry() filters out non-TYPE_SRB entries and the
SRB_NVME_CMD, SRB_BIDI_CMD and SRB_TM_CMD types, then falls through to a
SCSI fast path that assumes the command is an SRB_SCSI_CMD. The first
thing on that path, qla_chk_edif_rx_sa_delete_pending(), and the
subsequent handling both evaluate GET_CMD_SP(sp), i.e. sp->u.scmd.cmd.
The srb u union overlays the SCSI command pointer with other command
layouts (bsg_job, iocb_cmd). If firmware delivers an unexpected
STATUS_TYPE IOCB for a non-SCSI handle, sp->u.scmd.cmd can read as a
non-NULL garbage pointer, bypassing the NULL checks in
qla_chk_edif_rx_sa_delete_pending() and at the cp == NULL test, and
leading to a wild pointer dereference.
Reject any SRB whose type is not SRB_SCSI_CMD before entering the fast
path. The outstanding_cmds slot is left untouched so a genuinely
non-SCSI command still completes through its proper handler. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Don't query firmware state while chip is down
qla2x00_fw_state_show() initializes rval to QLA_FUNCTION_FAILED and jumps
to the out: label when the chip is down or EEH is busy. The out: block
then re-issued qla2x00_get_firmware_state() because rval != QLA_SUCCESS,
defeating the chip-down/EEH-busy guards and issuing a mailbox command
(outside optrom_mutex) during ISP reset or PCI error recovery, which can
hang the adapter. It also turned a normal in-lock mailbox failure into a
second unsynchronized mailbox attempt.
Make the out: fallback only mark the firmware state as unknown. The
mailbox is now issued at most once, inside optrom_mutex, and only when
the chip is up and not EEH-busy. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Clamp MSI-X derived queue counts to avoid truncation
ha->msix_count is u16, but ha->max_req_queues, ha->max_rsp_queues and
ha->max_qpairs are u8. Deriving the queue count as
"ha->max_req_queues = ha->msix_count - 1" therefore truncates: a board
(or a misconfigured/malicious hot-plugged device) advertising 257 MSI-X
vectors yields msix_count - 1 == 256, which truncates to 0. An MSI-X
count of 1 zeroes it as well, and in target mode the subsequent
"ha->max_req_queues--" then underflows 0 to 255.
When the count is 0, qla2x00_alloc_queues() calls
kzalloc_objs(struct req_que *, 0), which returns ZERO_SIZE_PTR. That is
not NULL, so the allocation check passes and the following
"ha->req_q_map[0] = req" dereferences ZERO_SIZE_PTR, corrupting memory
or crashing the kernel.
Add qla_calc_queue_count() to clamp the derived value into
[1, QLA_MAX_QUEUES - 1] so it always fits in u8 and is never zero, and
use it at all three derivation sites (qla25xx_iospace_config(),
qla83xx_iospace_config() and qla24xx_enable_msix()). Also guard the
target-mode decrement so it cannot reintroduce a zero (which would in
turn underflow max_qpairs). |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Hold qpair lock when sending NVMe LS reject
qla_nvme_ls_reject_iocb() allocates from and advances the request ring
through __qla2x00_alloc_iocbs() (which assumes the hardware_lock is
held) and qla2x00_start_iocbs() (which advances the ring and rings the
request-in doorbell), but takes no lock itself. Two of its callers
invoke it without the producer lock held:
- qla_nvme_xmt_ls_rsp(), the NVMe-FC .xmt_ls_rsp transport callback, on
its error path, and
- qla2xxx_process_purls_pkt(), run from the purex work/DPC context.
Both use ha->base_qpair, whose qp_lock_ptr is hardware_lock, so they can
run concurrently with normal I/O submission on the base ring and corrupt
the ring producer state, leading to duplicated or dropped commands. The
third caller, qla2xxx_process_purls_iocb(), runs inside
qla24xx_process_response_queue() with the qpair lock already held and is
safe; that is also why the lock cannot be taken inside the helper itself
(it would recursively re-acquire hardware_lock on the response path).
Take qp_lock_ptr around the two unlocked callers and document the helper
as caller-locked. Both run in process context, so spin_lock_irqsave() is
used and nothing in the locked region sleeps. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Hold vport reference in qla24xx_report_id_acquisition()
In the format 1 path, the virtual port is located on ha->vp_list while
holding vport_slock, but the lock is dropped before vp is used:
qla_update_host_map() is called and VP_IDX_ACQUIRED/REGISTER_FC4_NEEDED/
REGISTER_FDMI_NEEDED are set on vp. No reference is taken across that
window, so a concurrent qla24xx_deallocate_vp_id() can tear the vport
down and free it, leading to a use-after-free.
Take a vport reference (vref_count) under vport_slock when the matching
vp is found, and drop it after the last use of
vp. qla24xx_deallocate_vp_id() waits for vref_count to reach zero before
unlinking and freeing the vport, so the pointer stays valid. This
matches the reference idiom already used by the other ha->vp_list
traversals. |
| In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-ctrls: validate HEVC EXT SPS RPS counts
The HEVC SPS control carries the short-term and long-term RPS counts
that decoder drivers use to walk the matching EXT SPS dynamic arrays.
Reject SPS values that exceed the HEVC limits of 64 short-term sets and
32 long-term references so drivers cannot later index beyond those
controls.
Also reject EXT SPS ST RPS entries whose negative or positive picture
counts exceed the 16-entry arrays, or whose combined delta-POC count
exceeds the HEVC DPB maximum. |
| In the Linux kernel, the following vulnerability has been resolved:
media: cx23885: cancel NetUP CI work before teardown
netup_ci_exit() frees a netup_ci_state while its work item,
netup_read_ci_status(), may still be pending or running on the system
workqueue. The worker obtains the state with container_of() and
dereferences it, so it must not outlive the state.
netup_ci_init() queues the initial status read, and CI GPIO interrupts
subsequently queue the same work from netup_ci_slot_status(). During
remove, cx23885_finidev() calls free_irq() before the CI device is
unregistered. free_irq() prevents further IRQ handlers from running,
but does not drain work queued previously, so the worker can run after
netup_ci_exit() frees the state.
Call cancel_work_sync() before dvb_ca_en50221_release() and kfree().

| In the Linux kernel, the following vulnerability has been resolved:
media: cobalt: Avoid freeing ALSA private data twice
snd_cobalt_card_create() stores cobsc in sc->private_data and installs
snd_cobalt_card_private_free() as sc->private_free. From that point,
snd_card_free(sc) releases cobsc through the ALSA card cleanup path.
If cobalt_alsa_init() fails after snd_cobalt_card_create(), the
err_exit_free path calls snd_card_free(sc) and then kfree(cobsc). That
second free releases the same object again.
Remove the explicit kfree(cobsc) and leave ownership with the ALSA card.
This issue was found by a static analysis checker and confirmed by
manual source review. |

| The Popup Maker – Boost Sales, Conversions, Optins, Subscribers with the Ultimate WP Popup Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via values[Name] Parameter in all versions up to, and including, 1.24.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
