The "Dirty COW" privilege escalation vulnerability in the Linux kernel,
as reported in CVE-2016-5195 [1], has been patched in CoreOS Linux. The
update is currently rolling out to the Alpha [1192.2.0], Beta
[1185.2.0], and Stable [1122.3.0] channels. If automatic updates are
enabled (the default configuration), your server should be patched
within the next several hours (if it hasn’t already received the
update).
If automatic updates are disabled, you can force an update by running
`update_engine_client -check_for_update`.
