CVE-2025-10256 (GCVE-0-2025-10256)

Vulnerability from cvelistv5 – Published: 2026-02-18 20:26 – Updated: 2026-02-25 16:55

Title

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

Summary

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.

Severity ?

5.3 (Medium)
