FFmpeg through 9.0.2 contains a memory leak vulnerability in libavcodec/vdpau.c that allows attackers to exhaust heap memory by aborting pictures before end_frame. Attackers can supply crafted H.264 streams with malformed NAL units that repeatedly abandon pictures, leaking the bitstream_buffers table continuously and causing denial of service.
