CVE ID:	CVE-2014-3122
Description:	The try_to_unmap_cluster 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.
Test IDs:	1.3.6.1.4.1.25623.1.0.702926   1.3.6.1.4.1.25623.1.1.1.2.2014.0015
