Preventing Meltdown and Spectre on IBM i

To properly protect your IBM i systems, you need to install patches to both the OS and the firmware to address the Spectre and Meltdown security exposures.  Below are the required fixes depending on your OS level:

Release 7.1 – MF64553
Release 7.2 – MF64552
Release 7.3 – MF64551

The OS fix can be applied independently of the firmeware fix.  Keep in mind that BOTH the OS and firmware fixes are required to mitigate the security vulnerabilities presented by Spectre and Meltdown.
