Description OSIDB Bzimport 2025-09-11 06:13:10 UTC 
A potential 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. If the memory allocation for s->dump_buf fails, the subsequent dereference of the returned pointer may cause a crash (denial of service).

The issue was introduced in commit d3be186ed1, which added the dumpfile and dumpscale options to the Firequalizer filter, but did not handle memory allocation failures for s->dump_buf.
