Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-core package and not the kernel-zfcpdump-core package as distributed by Centos. See How to fix? for Centos:9 relevant fixed versions and status.

In the linux kernel, if IMA appraisal is used with the "ima_appraise=log" boot param, lockdown can be defeated with kexec on any machine when Secure Boot is disabled or unavailable. IMA prevents setting "ima_appraise=log" from the boot param when Secure Boot is enabled, but this does not cover cases where lockdown is used without Secure Boot.
