CVE-2025-4619Network attack vector

Firewall reboot via crafted dataplane packet

Published Nov 13, 2025 · Updated Nov 14, 2025

Denial of service in Palo Alto Networks PAN-OS and Prisma Access allows remote attackers to reboot firewalls via crafted dataplane packets. The dataplane packet-processing path improperly handles an unusual or exceptional condition in the packet and restarts the firewall. Exposure requires URL proxy or any decrypt policy; repeated packets can force maintenance mode and interrupt protected network traffic.
