CVE-2026-125252

FFmpeg through 9.0.2 contains a memory leak vulnerability in libavcodec/vaapi_decode.c that allows attackers to exhaust memory by supplying streams with slice parse errors. Attackers can craft H.264 or other VAAPI-decoded video where later slices fail to parse on every frame, continuously leaking VA parameter and slice buffers plus driver and heap memory.
