CVE-2025-10256  (opens in a new tab)

How to fix?

Upgrade Ubuntu:20.04 ffmpeg to version 7:4.2.7-0ubuntu0.1+esm11 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ffmpeg package and not the ffmpeg package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

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.
