It is attacked over the network, in a network appliance.

Am I affected by CVE-2026-0318?

Check whether you run Palo Alto Networks PAN-OS at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

CVE-2026-0318: Palo Alto Networks PAN-OS stack-based buffer overflow on Panorama

CVE-2026-0318 · Severity: info · Published 2026-10-14

A stack-based buffer overflow in Panorama's log processing functionality allows a network attacker to trigger repeated denial-of-service conditions that can force the Panorama system into maintenance mode. Panorama is a centralized management platform that controls and monitors enterprise firewalls, so repeated outages prevent administrators from managing and monitoring their security infrastructure. Standalone firewalls and cloud deployments are not affected.

Technologies: Palo Alto Networks PAN-OS. Vendors: Palo Alto Networks.

Technical details

A stack-based buffer overflow in the log processing component of PAN-OS on Panorama can be exploited remotely by unauthenticated attackers to cause denial of service. The vulnerability requires a specific configuration (Panorama in panorama-mode or management-only with Log Collector and a Collector Group configured) and allows an attacker to repeatedly crash Panorama and force it into maintenance mode. No code execution is possible; the impact is availability only.
