But it looks like users of the long-term supported CentOS 6 Linux operating system series are also affected, and the CentOS Errata and Security Advisory 2016:2105 informs them about an important kernel update. Yes, of course, we’re talking about the “Dirty COW” bug patched recently by Linus Torvalds himself and pushed to all supported Linux kernel branches, and documented at CVE-2016-5195. The CentOS 6 Linux series is based on the freely distributed source code of the Red Hat Enterprise Linux (RHEL) 6 operating system, which means that it always receives the latest security updates as soon as they are pushed upstream. Being used mainly in server environments, your CentOS 6 installation must always be patched and up to date, so make sure that you apply kernel-2.6.32-642.6.2.el6 immediately.
