F5 Networks BIG-IP : Linux kernel vulnerability (SOL15852)
Medium Nessus Plugin ID 79340
SynopsisThe remote device is missing a vendor-supplied security patch.
DescriptionThe 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.
