MediumCVSS 5.5/10Last modified Nov 10, 2026

Description

FFmpeg through 9.0.2 contains a NULL pointer dereference vulnerability in vble_decode_frame() in libavcodec/vble.c because it ignores init_get_bits() failure on oversized packets. Attackers can supply a crafted AVI file with a 268435452-byte VBLE frame, causing reads from a NULL bit reader buffer that crash the process.
