| In the Linux kernel, the following vulnerability has been resolved:
drm/dp/mst: fix buffer overflows in sideband chunk accumulation
drm_dp_sideband_append_payload() has three related bugs when processing
device-provided sideband reply data:
1. Zero-length curchunk_len underflow: msg_len is a 6-bit field taken
directly from the DP sideband header. If a device sends msg_len=0,
curchunk_len is set to zero. The condition (curchunk_idx >= curchunk_len)
is immediately true, and curchunk_len-1 wraps to 255 (u8 underflow).
drm_dp_msg_data_crc4() reads 255 bytes from chunk[48], then memcpy()
writes 255 bytes into msg[], both far out of bounds.
2. chunk[48] overflow: curchunk_len can reach 63 (6-bit field). chunk[] is
only 48 bytes. Multi-iteration payload assembly appends 16-byte blocks
until curchunk_idx reaches curchunk_len, writing up to 15 bytes past
the end of chunk[] into msg[].
3. msg[256] overflow: each chunk contributes (curchunk_len-1) bytes to
msg[]. No check ensures curlen + (curchunk_len-1) stays within msg[256],
so the memcpy can spill into adjacent struct fields.
All three are reachable from any DP MST device that can forge sideband
reply messages on a physical connection. |

| In the Linux kernel, the following vulnerability has been resolved:
drm/dp/mst: fix OOB reads on 2-byte fields in sideband reply parsers
Three sideband reply parsers read 16-bit fields as:
val = (raw->msg[idx] << 8) | (raw->msg[idx+1]);
and check bounds only after the fact. When idx == raw->curlen,
raw->msg[idx+1] reads one byte past the received message data into
the following struct fields (curchunk_len, curchunk_idx, curlen).
Affected functions:
- drm_dp_sideband_parse_enum_path_resources_ack()
full_payload_bw_number and avail_payload_bw_number fields
- drm_dp_sideband_parse_allocate_payload_ack()
allocated_pbn field
- drm_dp_sideband_parse_query_payload_ack()
allocated_pbn field
Fix by using a single combined check (idx + 2 > curlen) before each
2-byte read. Since the check is strictly tighter than idx > curlen,
no separate step is needed.

drm/i915/gem: Add missing nospec on parallel submit slot
Add missing Spectre mitigation for userspace controlled parallel
submission slot.

Product Security.

| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Check bounds in allocate_event_notification_slot
The valid event ids go from 0 to KFD_SIGNAL_EVENT_LIMIT
allocate_event_notification_slot has an option to specify
an event id to allocate at, used by CRIU. We weren't checking
the bounds on that value.
Check them.
v2: Lower bounds check is unecessary because of idr_alloc
already rejecting negative numbers. Upper bounds check should
be KFD_SIGNAL_EVENT_LIMIT since the signal mode mappings might
not yet exist

| In the Linux kernel, the following vulnerability has been resolved:
drm/virtio: bound EDID block reads to the response buffer
virtio_get_edid_block() validates the read offset only against the
device-supplied resp->size field, never against the fixed-size resp->edid
array. The EDID block index is driven by the device-supplied extension
count, so a malicious virtio-gpu backend can advertise a large size
together with a high block count and read far past the array into adjacent
kernel memory, which is then surfaced in the parsed EDID (an out-of-bounds
read / info leak).
Also reject any read whose end exceeds the size of the edid array.
Conforming EDID responses stay within the array and are unaffected. |

| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix bo->pin leaking in amdgpu_bo_create_reserved
amdgpu_bo_create_reserved() only allocates a new BO when
*bo_ptr (struct amdgpu_bo **bo_ptr as input parameter) is
NULL, it simply skips creation when *bo_ptr is non-NULL.
But it unconditionally reserves, pins, gart allocates
and maps the BO afterwards.
When the same non-NULL BO pointer is passed in again,
for example firmware buffers that live in adev and are
re-loaded on every resume / cp_resume / start
under AMDGPU_FW_LOAD_DIRECT, amdgpu_bo_pin() just increases
pin_count unconditionally, however the matching teardown only unpins
once, so pin_count never drops to zero, so TTM is not able
to move, swap or evict a BO, causing BO leaks.
This commit fixes this issue by only pinning the bo
once at creation, and repeated calls no longer
take additional pin references.

| In the Linux kernel, the following vulnerability has been resolved:
media: airspy: Return queued buffers on start_streaming() failure
The vb2 framework hands buffers to the driver via buf_queue() before
calling start_streaming(). If start_streaming() returns an error
without first returning those buffers via vb2_buffer_done(),
vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued
buffers leak.
airspy_start_streaming() returned -ENODEV early when the USB device had
been disconnected (s->udev == NULL) without returning any buffers that
buf_queue() had already accepted. Take v4l2_lock first and jump to the
existing err_clear_bit label, which already drains s->queued_bufs via
vb2_buffer_done(..., VB2_BUF_STATE_QUEUED) before unlocking.
This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo:
Return queued buffers on start_streaming() failure"). |

| In the Linux kernel, the following vulnerability has been resolved:
media: cedrus: skip invalid H.264 reference list entries
Cedrus consumes H.264 ref_pic_list0/ref_pic_list1 entries from the
stateless slice control and later uses their indices to look up
decode->dpb[] in _cedrus_write_ref_list().
Rejecting such controls in cedrus_try_ctrl() would break existing
userspace, since stateless H.264 reference lists may legitimately carry
out-of-range indices for missing references. Instead, guard the actual
DPB lookup in Cedrus and skip entries whose indices do not fit the fixed
V4L2_H264_NUM_DPB_ENTRIES array.
This keeps the fix local to the driver use site and avoids out-of-bounds
reads from malformed or unsupported reference list entries. |
| In the Linux kernel, the following vulnerability has been resolved:
media: cx231xx: fix devres lifetime
USB drivers bind to USB interfaces and any device managed resources
should have their lifetime tied to the interface rather than parent USB
device. This avoids issues like memory leaks when drivers are unbound
without their devices being physically disconnected (e.g. on probe
deferral or configuration changes).
Fix the driver state lifetime so that it is released on driver unbind. |
