Hotfix versions were inferred because the vendor did not list them explicitly: 11.1.10-h1, 11.1.10-h2, 11.1.10-h3, 11.1.10-h4, 11.1.10-h6 Known affected versions were inferred from fixed-version data and were not explicitly confirmed by the vendor: 11.2.9, 12.1.4-h5

The earliest recollection of this bug is traced back to PAN-OS 11.1.10-h5 - October 14, 2026. This bug is fixed in PAN-OS versions 11.1.10-h5, 11.1.10-h7, 12.1.5, 11.1.12, 11.2.10, 11.2.11, 11.1.14. ( PA-7500 and PA-5450 firewalls in FIPS-CC mode ) Fixed an issue where the affected firewalls would boot into maintenance mode when a reboot was initiated from the web interface. This was due to a device reboot triggering a power down to all slots, leading to maintenance mode. A hard reboot would allow the firewall to boot normally.
