PAN-OS: Denial of Service Vulnerabilities in Network Traffic Processing

Published Jul 9, 2026 · Updated Nov 10, 2026 · Assigned by palo_alto

Description

Multiple denial of service vulnerabilities in Palo Alto Networks PAN-OS® software allow an unauthenticated attacker with network access to cause a denial of service (DoS) condition by sending specially crafted network traffic to or through a dataplane interface. Repeated attempts to trigger this condition result in the firewall entering maintenance mode.

Panorama is not impacted by these vulnerabilities.
