CVE-2026-125102
Discovered by AISLEPUBLISHEDCWE-908
Description
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.
