NULL Pointer Dereference in FFmpeg CLJR Decoder

Publication date: 2026-11-09

Last updated on: 2026-11-09

Assigner: VulnCheck

Description
FFmpeg through 9.0.2 contains a NULL pointer dereference vulnerability in the Cirrus Logic AccuPak (CLJR) decoder in libavcodec/cljrdec.c because decode_frame() ignores init_get_bits() failure. Attackers can supply a crafted AVI file with a 2^28-byte CLJR frame that overflows the bit count, causing reads from a NULL buffer and crashing the process.
