Description Prasad Pandit 2013-12-10 12:14:11 UTC
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.
