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. (NVD)
