CVE-2014-3122

Priority
Medium
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.
Ubuntu-Description
Sasha Levin reported a bug in the Linux kernel's virtual memory management
subsystem. An unprivileged local user could exploit this flaw to cause a
denial of service (system crash).
