Discussion

File system extended ACLs provide access to files beyond what is allowed by the mode numbers of the files. If extended ACLs are present on the system's boot loader configuration file(s), these files may be vulnerable to unauthorized access or modification, which could compromise the system's boot process.

Check Content

Check the permissions of the file.
# ls -lLd /etc/zipl.conf

If the mode the file or directory contains a '+', an extended ACL is present. This is a finding.

Fix Text

Remove the extended ACL from the file.
# setfacl --remove-all /etc/zipl.conf
