AV:L/AC:L/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.14.3

Description The issue is related to errors in memory handling, specifically in the try to unmap cluster function in mm/rmap.c, which does not properly consider which pages must be locked. This allows local users to cause a denial of service (system crash) by triggering a memory-usage pattern that requires removal of page-table mappings. The vulnerability can be exploited to disrupt confidentiality, integrity, and availability of protected information.

Recommendations For Linux kernel versions prior to 3.14.3, update to version 3.14.3 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive memory areas to minimize the risk of exploitation.
