Dirty COW
Dirty COW (Dirty copy-on-write) is a computer security vulnerability for the Linux operating system kernel. It is a local privilege escalation bug that exploits a race condition in the implementation of the copy-on-write mechanism.[1][2] As of October 2016[update], it is actively being exploited.[2]
Although it is a local privilege escalation bug, remote attackers can use it in conjunction with other exploits that allow remote execution of non-privileged code to achieve remote root access on a computer.[1] The attack itself doesn't leave traces in the system log.[2]
It has the CVE designation CVE-2016-5195.[3] The Debian operating system distribution has announced that it has released a patch for the vulnerability.[4]
