Impact
A NULL pointer dereference in the gf_filter_in_parent_chain function of GPAC Project/MP4Box before version 26.02.0 can be triggered by a crafted media file, causing the application to crash and leading to a denial of service. The weakness is a dereference of an invalid pointer, which underlines the potential for service disruption when the software processes malicious content.
Affected Systems
All users of GPAC Project/MP4Box versions earlier than 26.02.0 are vulnerable. The issue resides in the filter_pid.c component of the project, affecting any deployment that processes MP4 or other supported media containers with this version of the tool.
Risk and Exploitability
The vulnerability enables processes that can supply arbitrary input to MP4Box to stop the service. The EPSS score is not available, and the issue is not listed in CISA KEV; the operational impact is clear, but no evidence of widespread exploitation is available.
