SUSE CVE-2022-21505

In the linux kernel, if IMA appraisal is used with the "imaappraise=log" boot param, lockdown can be defeated with kexec on any machine when Secure Boot is disabled or unavailable. IMA prevents setting "imaappraise=log" from the boot param when Secure Boot is enabled, but this does not cover case...
