Last Modified: Sep 13, 2023

Affected Product(s):
BIG-IP TMOS(all modules)

Known Affected Versions:, 13.1.4,

Fixed In:

Opened: Jun 09, 2021

Severity: 2-Critical


After EHF installation, the Linux kernel contains the base installation version only.


Any new patches/changes present at the new Linux kernel which is part of the Hotfix image will not be effective (run).


Hotfix BIG-IP ISO should contain the Kernel RPM.


When the fix requires changes to the Linux kernel, install the regular full ISO instead of the hotfix.

Fix Information

Updated the install post scripts to handle new Linux kernel files properly.
