Known affected versions were inferred from fixed-version data and were not explicitly confirmed by the vendor: 10.1.8-h8, 10.2.3-h14

The earliest recollection of this bug is traced back to PAN-OS 10.1.9 - May 06, 2026. This bug is fixed in PAN-OS versions 10.2.4, 10.1.9. Fixed an issue with firewalls in HA configurations where the passive firewall attempted to connect to a hardware security module (HSM) client when a service route was configured, which caused dynamic updates and software updates to fail.
