CVE-2026-125179 is a low-severity vulnerability rated 3.3/10 on the CVSS scale. FFmpeg through 9.0.2 contains an uninitialized memory vulnerability in the VQA video decoder in libavcodec/vqavideo.c that allows attackers to disclose heap memory via a crafted VQA file. Attackers can supply a Westwood VQA file omitting or truncating the CBF0/CBFZ codebook chunk, causing vqa_decode_frame() to render frames from leftover heap bytes visible in decoded output.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
