CVE-2025-0121

Agent crash via undisclosed null pointer dereference

Published Apr 11, 2025 · Updated Apr 11, 2025

Null pointer dereference in affected Windows releases of Palo Alto Networks Cortex XDR Agent allows local users to crash the agent. The vendor identifies a null pointer dereference but has not published the affected process, function, or attacker-controlled input that triggers it. Low-privileged local access is sufficient, no special configuration is required, and the crash leaves malware activity undetected until protection recovers.
