Title
media: verisilicon: hantro: bound G2 HEVC tile loop to the buffer capacity
Summary
In the Linux kernel, the following vulnerability has been resolved: media: verisilicon: hantro: bound G2 HEVC tile loop to the buffer capacity prepare_tile_info_buffer() writes one entry per tile into the tile_sizes DMA buffer, sized for a grid equal to the PPS uAPI array capacity. Use the bounded v4l2_hevc_pps_num_tile_columns() / v4l2_hevc_pps_num_tile_rows() helpers so the loops stay inside the buffer.
Severity
