| Description: | The __munlock_pagevec function in mm/mlock.c in the Linux kernel before 4.11.4 allows local users to cause a denial of service (NR_MLOCK accounting corruption) via crafted use of mlockall and munlockall system calls. Kefeng Wang discovered that a race condition existed in the memory locking implementation in the Linux kernel. A local attacker could use this to cause a denial of service.
