CVE-2026-125236
FFmpeg through 9.0.2 contains a memory leak vulnerability in alloc_frame() in libavcodec/vvc/refs.c that leaks SPS and PPS references when frame buffer allocation fails. Attackers can supply a crafted VVC (H.266) stream that repeatedly replaces parameter sets, steadily growing memory use and causing denial of service.
