| In the Linux kernel, the following vulnerability has been resolved:
ipvs: reject invalid states in connection template sync records
IPVS sync receivers validate protocol states before creating or updating a
connection. For connection templates, however, they only log states outside
the template state range and still store the value in the connection.
A template can be returned by ordinary connection lookup. TCP and SCTP then
use the invalid state as an index into their transition tables.
Reject invalid template states in both sync protocol versions before
looking up or modifying a connection. The version 1 path handles both
IPv4 and IPv6 records. |
| In the Linux kernel, the following vulnerability has been resolved:
media: mediatek: vcodec: bound AV1 tile-start copy to the array capacity
vdec_av1_slice_setup_tile() copies tile_cols + 1 / tile_rows + 1 entries
into mi_col_starts[] / mi_row_starts[] from the bitstream tile_info. Bound
the copy to the array capacity. |
| In the Linux kernel, the following vulnerability has been resolved:
media: verisilicon: rockchip: guard VPU981 AV1 divisor and tile buffer
rockchip_vpu981_av1_dec_set_tile_info() divides context_update_tile_id by
tile_info->tile_cols and writes one descriptor per tile into the tile_info
DMA buffer, which holds AV1_MAX_TILES entries; tile_cols and tile_rows
come from the bitstream. Guard the division against a zero tile_cols by
initialising the context-update values to zero and computing them only
when tile_cols is non-zero, and stop the descriptor writes once the
tile_info buffer is full. The tile geometry written to the hardware
registers is left unmodified; the per-dimension and total tile bounds are
enforced by the control validation. |
| In the Linux kernel, the following vulnerability has been resolved:
media: verisilicon: rockchip: reject AV1 frames exceeding the tile capacity
rockchip_vpu981_av1_dec_set_tile_info() indexes the tile group entry
array by tile1 * tile_cols + tile0, reading up to tile_cols * tile_rows
entries, lays out one descriptor per tile in the AV1_MAX_TILES tile_info
buffer, and programs the real tile_cols / tile_rows into the hardware.
The tile group entry control is a dynamic array sized to the number of
entries userspace submitted, independent of tile_cols / tile_rows, so a
frame that claims more tiles than entries reads past the array. A frame
that claims more than AV1_MAX_TILES tiles also leaves the hardware
programmed for more tiles than the descriptor buffer holds.
Reject both in prepare_run(): tile_cols * tile_rows must not exceed the
submitted entry count or AV1_MAX_TILES. The entry count is read via
v4l2_ctrl_find() (ctrl->elems). This mirrors the bound the mediatek AV1
decoder already enforces. |
| In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-ctrls: validate HEVC tile counts
The stateless HEVC decoders read num_tile_columns_minus1 + 1 entries from
column_width_minus1[] and num_tile_rows_minus1 + 1 from row_height_minus1[]
and use them as tile-loop bounds, but std_validate_compound() does not
bound these u8 counts. Reject a V4L2_CTRL_TYPE_HEVC_PPS with tiling
enabled whose tile counts exceed the uAPI array capacity, mirroring the
existing compound-control range checks. |
| In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-ctrls: validate AV1 tile counts
The stateless AV1 decoders use tile_info.tile_cols and tile_rows as loop
bounds and as indices into the mi_*_starts[] and *_in_sbs_minus_1[]
arrays, as the divisor for context_update_tile_id, and their product
bounds the per-tile descriptor buffers, but std_validate_compound() does
not bound these u8 fields. Reject a V4L2_CTRL_TYPE_AV1_FRAME whose
tile_cols or tile_rows exceeds V4L2_AV1_MAX_TILE_COLS / _ROWS, or whose
product exceeds V4L2_AV1_MAX_TILE_COUNT. A zero tile count is left to the
consuming driver so the zero-initialised control that existing userspace
submits is still accepted. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix one-byte OOB read in smb2_parse_native_symlink()
When parsing a share-root relative native symlink, memcpy copies
smb_target+1 (skipping the leading separator) but uses
strlen(smb_target)+1 as the length, reading one byte past the
allocated buffer.
This fixes the following KASAN splat when accessing an SMB symlink
with a target of '\a\b':

| In the Linux kernel, the following vulnerability has been resolved:
net: usb: pegasus: don't rely on id table pointer arithmetic
The current code is broken when dynamic ID is involved; in such cases
usb_device_id parameter of probe lives on the heap and the pointer
arithmetic will get an index that is wildly out of bound. Instead of
keeping a side table for additional information, use driver_info field of
the usb_device_id.
The dynamic ID parsing code needs to be updated for this; convert it to
just write to the reserved entry for dynamic ID and remove the weird loop. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: xusbatm: don't rely on id table pointer arithmetic
The current code is broken when dynamic ID is involved; in such cases
usb_device_id parameter of probe lives on the heap and the pointer
arithmetic will get an index that is wildly out of bound. xusbatm
initialize the USB device IDs dynamically so it can just use driver_info
too.
Even with conversion, xusbatm still cannot support dynamic IDs, so also set
no_dynamic_id. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: nl80211: reject beacons with bad HE operation
The HE operation element not only needs to be longer than
the fixed part, but also have an appropriate size for the
variable part inside of it. Check this. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Check bounds for allocate_sdma_queue restore_sdma_id
allocate_sdma_queue has an option where the sdma queue id can be
specified (used by CRIU). We weren't bounds-checking that
value.
Confirm it's less than the maximum number of queues. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Fix OOB memory exposure in get_wave_state()
The get_wave_state() function for v9 trusts cp_hqd_cntl_stack_size and
cp_hqd_cntl_stack_offset values read directly from the MQD, which are
written by GPU microcode and fully attacker-controlled on the
CRIU-restore path (via AMDKFD_IOC_RESTORE_PROCESS with H3).
this leads to an unbounded copy_to_user() that can leak adjacent
GTT/kernel memory. If offset > size, integer underflow produces a ~4 GiB
read length, if size is set to 1 MiB against a 4 KiB allocation, we leak
1 MiB of adjacent kernel memory (other queues' MQDs, ring buffers, KASLR
pointers).
Fix by clamping both cp_hqd_cntl_stack_size to the actual allocated
buffer size (q->ctl_stack_size) and cp_hqd_cntl_stack_offset to the
clamped size before performing arithmetic and copy_to_user().
This ensures we never read beyond the allocated kernel BO regardless of
attacker-supplied MQD field values. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Check bounds on allocate_doorbell
allocated_doorbell has an option to set the doorbell id
to a specific value (used by CRIU). This value was not
bounds checked.
Check to confirm it's less than KFD_MAX_NUM_OF_QUEUES_PER_PROCESS. |
| In the Linux kernel, the following vulnerability has been resolved:
jfs: handle set_blocksize failures
jfs uses buffer_heads, which don't handle block size > PAGE_SIZE well.
Without this, mounting we will hit the
BUG_ON(offset >= folio_size(folio));
in folio_set_bh on the first __bread_gfp call. |
| In the Linux kernel, the following vulnerability has been resolved:
omfs: handle set_blocksize failures

size parameter being passed to memcpy(). |

access. |
