## Overview

In the Linux kernel, the following vulnerability has been resolved:

media: rkvdec: bound HEVC tile loops and PPS id to the array capacity

compute_tiles_uniform() and compute_tiles_non_uniform() loop over
num_tile_columns_minus1 + 1 / num_tile_rows_minus1 + 1 entries, and
assemble_hw_pps() writes one COLUMN_WIDTH / ROW_HEIGHT register per tile
and indexes priv_tbl->param_set[] by pic_parameter_set_id, all taken from
the untrusted PPS. Use the bounded v4l2_hevc_pps_num_tile_columns() /
v4l2_hevc_pps_num_tile_rows() helpers for the tile loops, and bail out of
assemble_hw_pps() before indexing priv_tbl->param_set[] with an
out-of-range pic_parameter_set_id, so the writes stay within the hardware
tables.
