CVE-2026-12706 · Ffmpeg: ffmpeg: heap use-after-free read in rasc decoder decode_move()

This page contains facts from public vulnerability sources. Check the original advisory before updating.

A use-after-free vulnerability was found in FFmpeg's RASC video decoder. The decode_move() function initializes a read pointer into a decompressed buffer, but a subsequent reallocation of that same buffer during move-table processing leaves the pointer dangling. An attacker could exploit this by providing a specially crafted AVI file containing a malicious RASC video stream. When a user opens or plays the file, the decoder reads from freed heap memory, which could lead to a denial of service (crash).
