FFmpeg through 9.0.2 contains a heap buffer overflow vulnerability in vaapi_hevc_start_frame() in libavcodec/vaapi_hevc.c that copies unbounded PPS tile counts into fixed-size arrays. Attackers can supply a crafted HEVC bitstream with a large picture and many tiles to write controlled 16-bit values past heap-allocated hwaccel data, corrupting memory in applications decoding with VAAPI.
