Discussion

The "noexec" mount option causes the system to not execute binary files. This option must be used for mounting any file system not containing approved binary files, as they may be incompatible. Executing files from untrusted file systems increases the opportunity for nonprivileged users to attain unauthorized administrative access.

Verify "/home" is mounted with the "noexec" option with the following command:

Note: If a separate file system has not been created for the user home directories (user home directories are mounted under "/"), this is automatically a finding, as the "noexec" option cannot be used on the "/" system.

$ mount | grep /home

/dev/mapper/luks-10a20c46-483d-4d12-831f-5328eda18fd1 on /home type xfs (rw,noexec,nosuid,nodev,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota)

If the "/home" file system is mounted without the "noexec" option, this is a finding.
