What is CVE-2024-47602?

A null pointer dereference vulnerability exists in the gst_matroska_demux_add_wvpk_header function within the GStreamer library. This issue arises from insufficient validation of the stream->codec_priv pointer. If this pointer is NULL, a subsequent call to GST_READ_UINT16_LE will attempt to dereference it. This situation can cause the application utilizing GStreamer to crash unexpectedly. The vulnerability has been addressed in version 1.24.10 of GStreamer, ensuring proper checks are in place to prevent such dereferences.
