Answer in brief
CVE-2026-0269 records a Medium severity (CVSS 5.7) vulnerability in PAN-OS: Denial of Service (DoS) in Tunnel Traffic Processing. The current sources do not mark it as known exploited. The current feed maps Palo Alto Networks/PAN-OS (generic), Siemens/RUGGEDCOM APE1808 (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 5.7. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

A memory corruption vulnerability in the processing of tunnel traffic in Palo Alto Networks PAN-OS® software allows an authenticated user to initiate system reboots using a maliciously crafted packet. Repeated attempts to initiate a reboot causes the firewall to enter maintenance mode. Panorama, Cloud NGFW, and Prisma® Access are not impacted by this vulnerability.
