Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： 媒体子系统：v4l2-ctrls：验证 AV1 的瓦片（tile）数量 无状态 AV1 解码器使用 和 作为循环边界，并将其用作 和 数组的索引、 的除数，且它们的乘积用于限定每个瓦片描述符缓冲区的大小。然而， 并未对这些 类型的字段进行边界检查。 现在，当提交的 控制项中 或 超过 / ，或其乘积超过 时，将拒绝该请求。 零瓦片数量留给消费该控制项的驱动处理，因此现有用户空间提交的零初始化控制项仍可被正常接受。

Vulnerability Title
media: v4l2-ctrls: validate AV1 tile counts
Source: CVE Program / CVE List V5
Vulnerability Description
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.
