CVE-2024-47601

Application crash via unchecked demuxer buffer

Published Dec 11, 2024 · Updated Nov 3, 2025

Null pointer dereference in the Matroska/WebM demuxer in GStreamer before 1.24.10 allows attackers to crash applications via crafted media. The gst_matroska_demux_parse_blockgroup_or_simpleblock function dereferences a GstBuffer sub pointer without first verifying that it is non-null. Processing the malformed media is required, and the resulting segmentation fault interrupts the affected application without reported data disclosure or modification.
