Linux kernel kernel's Memory Management subsystem is vulnerable to a crash caused by unlocked memory pages. It could occur during the memory page migration or while cleaning the swap cache pages.

An unprivileged user/program could use this flaw to crash the system kernel, resulting in DoS.

Red Hat

The trytounmapcluster function in mm/rmap.c in the Linux kernel before 3.14.3 does not properly consider which pages must be locked, which allows local users to cause a denial of service (system crash) by triggering a memory-usage pattern that requires removal of page-table mappings.
