CVE-2026-125707

medium

Description

A flaw was found in GStreamer's MXF demuxer. When an application processes a crafted MXF file, an off-by-one bounds check can allow a one-byte write past the logical end of a temporal offset array. This may corrupt memory and cause the application to crash. The extent of the impact has not been demonstrated by a runtime test.
