Vulnerability Discussion
The "/var/tmp" partition is used as temporary storage by many programs. Placing "/var/tmp" in its own partition enables the setting of more restrictive mount options, which can help protect programs that use it.
Check
Verify that a separate file system/partition has been created for "/var/tmp" with the following command:
$ mount | grep /var/tmp
/dev/mapper/luks-0e7206e7-bfb1-4a23-ae14-b9cea7cf76d5 on /var/tmp type xfs (rw,nosuid,nodev,noexec,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota)
If a separate entry for "/var/tmp" is not in use, this is a finding.
Fix
Migrate the "/var/tmp" path onto a separate file system.
