InformationThe nosuid mount option specifies that the filesystem cannot contain setuid files.
Since the /tmp filesystem is only intended for temporary file storage, set this option to ensure that users cannot create setuid files in /tmp.
SolutionEdit /etc/systemd/system/local-fs.target.wants/tmp.mount to add nodev to the /tmp mount options:
Run the following command to remount /tmp :
# mount -o remount,nodev /tmp
systemd includes the tmp.mount service which should be used instead of configuring /etc/fstab. Mounting options are configured in the Options setting in /etc/systemd/system/local-fs.target.wants/tmp.mount.
