## Overview

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.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
