Information

Amazon Linux 2023 must mount /dev/shm with the nosuid option.

GROUP ID: V-274180RULE ID: SV-274180r1120528

The "nosuid" mount option causes the system to not execute "setuid" and "setgid" files with owner privileges. This option must be used for mounting any file system not containing approved "setuid" and "setguid" files. Executing files from untrusted file systems increases the opportunity for nonprivileged users to attain unauthorized administrative access.

Solution

Configure Amazon Linux 2023 so that "/dev/shm" is mounted with the "nosuid" option.

Modify "/etc/fstab" to use the "nosuid" option on the "/dev/shm" file system.
