CVE-2016-5195 kernel: mm: privilege escalation via MAP_PRIVATE COW breakageA race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.
