A frame\nthat claims more than AV1_MAX_TILES tiles also leaves the hardware\nprogrammed for more tiles than the descriptor buffer holds.\n\nReject both in prepare_run(): tile_cols * tile_rows must not exceed the\nsubmitted entry count or AV1_MAX_TILES. The entry count is read via\nv4l2_ctrl_find() (ctrl->elems). This mirrors the bound the mediatek AV1\ndecoder already enforces.","state":0,"publishedAt":"2026-09-25T10:21:59.95+00:00","modifiedAt":"2026-10-19T09:09:39.822+00:00","affected":[{"ecosystem":"Vendor
