CVE-2026-125188

LowCVSS 2.5/10Last modified Nov 10, 2026

Description

FFmpeg through 9.0.2 contains a heap out-of-bounds read vulnerability in libavcodec/proresenc_anatoliy.c that occurs when the prores_aw encoder processes interlaced, odd-height frames. Attackers can supply odd-height video that causes subimage_with_fill_template() to fill padding rows from memory before the fill_y buffer, leaking heap contents into the encoded output.
