Doc Text:
A flaw was found in FFmpeg. The DXA video decoder fails to properly initialize internal memory buffers before copying data into output video frames. By tricking a user or service into processing a specially crafted DXA video file, an attacker can access sensitive residual heap memory in the decoded output, leading to information disclosure.

Description OSIDB Bzimport 2026-11-10 19:40:16 UTC
FFmpeg through 9.0.2 contains an uninitialized memory vulnerability in the DXA decoder in libavcodec/dxa.c that allows attackers to disclose heap memory via crafted DXA files. Attackers can supply a DXA video with a type 4 frame that copies the uninitialized decomp_buf buffer into output pictures, exposing leftover heap contents in decoded frames.
