CVE-2026-90685Hinoki check available

Media-processing crash via active-bitstream assertion

Published Sep 14, 2026 · Updated Sep 14, 2026

Reachable assertion in GPAC MP4Box f1219cde allows local users to crash media processing via a crafted file. The lsr_exec_command_list function in src/laser/lsr_dec.c assumes the decoder has no active bitstream and calls gf_assert when codec->bs is already set instead of rejecting that state. Local access and processing attacker-controlled LASeR scene data are required; successful exploitation aborts the affected MP4Box process without reported data disclosure or modification.
