  Multiple race conditions in ipc/shm.c in the Linux kernel before 3.12.2
  allow local users to cause a denial of service (use-after-free and system
  crash) or possibly have unspecified other impact via a crafted application
  that uses shmctl IPC_RMID operations in conjunction with other shm system
  calls.
