Ensure that all known CPU vulnerabilities are mitigated. This ensures that known attacks, such as Spectre, Meltdown, etc. either do not affect the node or are mitigated via software.
Vulnerability mitigation ensures that known attacks cannot be exploited.
Impact analysis should be performed on a per-mitigation basis.
View CPU mitigations:
$ ls /sys/devices/system/cpu/vulnerabilities
Output may resemble the following:
"Not affected" CPU is not affected by the vulnerability
"Vulnerable" CPU is affected and no mitigation in effect
"Mitigation: $M" CPU is affected and mitigation $M is in effect
Add the appropriate kernel arguments to the MachineConfigPools of the workers nodes and reboot them. See Documentation Chapter 1.Customizing nodes | Red Hat Product Documentation
