Linux kernel: Dirty COW (CVE-2016-5195)

REF: https://github.com/dirtycow/dirtycow.github.io/wiki/VulnerabilityDetails

Impact

• 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.
• This flaw allows an attacker with a local system account to modify on-disk binaries, bypassing the standard permission mechanisms that would prevent modification without an appropriate permission set.
