Summary

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.
