InformationThe nosuid mount option specifies that the filesystem cannot contain setuid files.
Note: /dev/shm is mounted automatically by systemd. /dev/shm needs to be added to /etc/fstab to add mount options even though it is already being mounted on boot.
Setting this option on a file system prevents users from introducing privileged programs onto the system and allowing non-root users to execute them.
SolutionEdit the /etc/fstab file and add nosuid to the fourth field (mounting options) for the /dev/shm partition. See the fstab(5) manual page for more information.
Run the following command to remount /dev/shm:
# mount -o remount,noexec,nodev,nosuid /dev/shm
