  3. CVE-2026-107695
FFmpeg before 8.1.3 contains an infinite loop vulnerability in the HLS demuxer that allows remote attackers to cause denial of service because parse_playlist() accepts Master Playlist tags inside Media Playlists. Attackers can trick victims into opening a crafted self-referencing playlist that endlessly adds variants in hls_read_header(), causing unbounded CPU and I/O consumption.
