FKIE_CVE-2014-3122

Vulnerability from fkie_nvd - Published: 2014-05-11 21:55 - Updated: 2026-06-17 00:07
Severity
Summary
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.
