Memory Usage Pattern Denial of Service Vulnerability in Linux Kernel

CVE-2014-3122 · MEDIUM Severity

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

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.
