CVE-2026-90684Hinoki check available

Process abort via misordered scene node fields

Published Sep 14, 2026 · Updated Sep 14, 2026

Reachable assertion in MP4Box at GPAC f1219cde allows local users to crash the process by opening a crafted media file. Generated MPEG-4 node structures place child-list members at offsets inconsistent with field metadata, so gf_node_get_field_count reaches its assertion while enumerating a crafted scene. Local processing of attacker-supplied scene content is required, and the bounded consequence is an MP4Box process abort.
