CVE-2026-1415Public exploitHinoki check available

Platform-dependent crash via NULL handler formatting

Published Jan 26, 2026 · Updated Jan 26, 2026

NULL pointer dereference in GPAC 2.4.0 and earlier allows local users to crash MP4Box by exporting metadata from a crafted MP4 file. gf_media_export_webvtt_metadata passes a NULL handler name from a nameless hdlr box to gf_fprintf with the %s format specifier. The file must be processed with WebVTT metadata export; Windows and other non-glibc platforms crash, while glibc prints (null) instead.
