Linux kernel built with the Sys V IPC support(CONFGI_SYSVIPC) is vulnerable to a use-after-free flaw caused by a race condition during deletion of a shared memory file object. It could occur while using shmctl(IPC_RMID) along with other shm system calls. A user/program could use this flaw to crash a system resulting in DoS.
