CVE-2026-90613Hinoki check available

Process crash via inconsistent sample-to-chunk metadata

Published Sep 14, 2026 · Updated Sep 14, 2026

Reachable assertion in GPAC MP4Box at commit f1219cde allows local users to crash the process by opening a crafted MP4 file. stbl_GetSampleInfos asserts that firstSampleInCurrentChunk does not exceed the requested sample before rejecting inconsistent sample-to-chunk metadata. A local user must cause MP4Box to parse attacker-controlled ISOBMFF content; the bounded consequence is termination of that process.
