## Overview

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.
