The earliest recollection of this bug is traced back to PAN-OS 10.2.18-h5 - July 21, 2026. This bug is fixed in PAN-OS versions 11.1.13-h2, 11.2.11, 11.1.14, 11.1.6-h29, 11.1.10-h21, 11.2.10-h5, 10.2.18-h5, 11.2.7-h12, 12.1.5. Fixed an issue where the firewalls restarted due to a function lacking a NULL-pointer sanity check. Firewalls may restart unexpectedly due to an internal error in content inspection processing. This issue can occur when the firewall is performing antivirus scanning, URL filtering, or WildFire analysis.
