The Linux vulnerability called Dirty COW (CVE-2016-5195) was first disclosed to the public in 2016.

It is categorized as a serious privilege escalation flaw that allows an attacker to gain root access on the targeted system. Dirty COW attacks on Android has been silent since its discovery, perhaps because it took attackers some time to build a stable exploit for major devices.
