Description OSIDB Bzimport 2026-11-10 20:23:50 UTC 
FFmpeg through 9.0.2 contains a NULL pointer dereference vulnerability in libavcodec/jvdec.c that allows attackers to crash applications by supplying oversized JV video packets. Attackers can pass a roughly 268435460-byte packet through the libavcodec API, overflowing the bit count so decode_frame() reads from a NULL buffer and causes denial of service.
