Accessing shared memory objects via the filesystem On Linux, shared memory objects are created in a (tmpfs(5)) virtual filesystem, normally mounted under /dev/shm. Since kernel 2.6. 19, Linux supports the use of access control lists (ACLs) to control the permissions of objects in the virtual filesystem.
