Vulnerability Discussion
Ensuring that "/home" is mounted on its own partition enables the setting of more restrictive mount options, and also helps ensure that users cannot trivially fill partitions used for log or audit data storage.
Check
Verify that a separate file system/partition has been created for "/home" with the following command:
$ mount | grep /home
/dev/mapper/luks-10a20c46-483d-4d12-831f-5328eda18fd1 on /home type xfs (rw,nosuid,nodev,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota)
If a separate entry for "/home" is not in use, this is a finding.
Fix
Migrate the "/home" directory onto a separate file system/partition.
