Ffmpeg: null pointer dereference in firequalizer filter (libavfilter/af_firequalizer.c)

Published Feb 18, 2026

Modified 3 months ago

Details

A NULL pointer dereference vulnerability exists in FFmpeg’s Firequalizer filter (libavfilter/af_firequalizer.c) due to a missing check on the return value of av_malloc_array() in the config_input() function. An attacker could exploit this by tricking a victim into processing a crafted media file with the Firequalizer filter enabled, causing the application to dereference a NULL pointer and crash, leading to denial of service.
