Description OSIDB Bzimport 2026-11-10 19:27:00 UTC 
FFmpeg through 9.0.2 contains an uncontrolled resource consumption vulnerability in parse_frame_header() in libavcodec/jpegxl_parser.c that fails to validate TOC entry counts against remaining input. Attackers can supply a crafted JPEG XL frame header with a permuted TOC and huge toc_count, making the parser loop excessively and exhaust CPU.
