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.
SolutionRun the following command to remount /dev/shm:
# mount -o remount,noexec /dev/shm
/etc is stateless on Container-Optimized OS. Therefore, /etc cannot be used to make these changes persistent across reboots. The steps mentioned above needs to be performed after every boot.
