CVE-2026-125170

medium

Description

FFmpeg through 9.0.2 contains an uninitialized memory disclosure vulnerability in targa_decode_rle() in libavcodec/targa.c caused by missing packet length checks. Attackers can supply truncated RLE-compressed TGA images so decoded frames contain leftover heap buffer data and replicated uninitialized stack bytes.
