Last modified
CVE-2026-125174 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. FFmpeg before 8.1.3 and 9.x before 9.0.2 contains a NULL pointer dereference vulnerability in ff_hap_set_chunk_count() in libavcodec/hap.c, where a shadowed return variable masks reallocation failures. Attackers can supply a crafted Hap video frame with an oversized chunk count so the decoder writes through a NULL chunk table, crashing the application.. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
