Last modified
CVE-2025-10256 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.30% chance of exploitation in the next 30 days.
