InformationThe noexec mount option specifies that the filesystem cannot contain executable binaries.
Setting this option on a file system prevents users from executing programs from shared memory. This deters users from introducing potentially malicious software on the system.
SolutionEdit the /etc/fstab file and add noexec to the fourth field (mounting options) for the /dev/shm partition.
<device> /dev/shm <fstype> defaults,rw,nosuid,nodev,noexec,relatime 0 0
Run the following command to remount /dev/shm with the configured options:
# mount -o remount /dev/shm
NOTE It is recommended to use tmpfs as the device/filesystem type as /dev/shm is used as shared memory space by applications.
