Doc Text:
A flaw was found in FFmpeg. This vulnerability allows for information disclosure due to missing validation in the TAK (Tom's lossless Audio Kompressor) audio decoder, which fails to ensure multichannel decorrelation lists cover every channel. An attacker could exploit this flaw by providing a specially crafted multichannel TAK audio file, causing undecoded sample buffers to leak uninitialized heap memory into the decoded audio output.

Description OSIDB Bzimport 2026-11-10 20:21:14 UTC
FFmpeg through 9.0.2 contains an uninitialized memory disclosure vulnerability in tak_decode_frame() in libavcodec/takdec.c that fails to verify multichannel decorrelation lists cover every channel. Attackers can supply crafted multichannel TAK files omitting channels from the list, causing undecoded sample buffers to leak heap memory through decoded audio.
