CVE-2026-90683Hinoki check available

Local process crash via zero-count node unregister

Published Sep 14, 2026 · Updated Sep 14, 2026

Reachable assertion in MP4Box at GPAC f1219cde allows local users to crash the process by processing a crafted MP4 file. The gf_node_unregister function assumes that a scene-graph node has a nonzero instance count and asserts when untrusted scene data causes an extra unregister operation. Exploitation requires a local MP4Box invocation against the crafted file, and the demonstrated consequence is process termination rather than persistent system disruption.
