Description OSIDB Bzimport 2026-09-25 10:44:19 UTC
In the Linux kernel, the following vulnerability has been resolved:

media: verisilicon: rockchip: guard VPU981 AV1 divisor and tile buffer

rockchip_vpu981_av1_dec_set_tile_info() divides context_update_tile_id by
tile_info->tile_cols and writes one descriptor per tile into the tile_info
DMA buffer, which holds AV1_MAX_TILES entries; tile_cols and tile_rows
come from the bitstream. Guard the division against a zero tile_cols by
initialising the context-update values to zero and computing them only
when tile_cols is non-zero, and stop the descriptor writes once the
tile_info buffer is full. The tile geometry written to the hardware
registers is left unmodified; the per-dimension and total tile bounds are
enforced by the control validation.
