CoreOS 1122.3.0 is now the current stable version of the Linux-based operating system, shipping with a fix for the privilege escalation vulnerability in Linux kernel that’s fully documented at CVE-2016-5195, as well as a patch for a denial of service (DoS) issue with the systemd init system, documented at CVE-2016-7795. On the other hand, the Beta channel of CoreOS is now at version 1185.2.0, and the Alpha channel at version 1192.2.0, also shipping with the patches mentioned above, but running a more recent kernel from the now deprecated Linux 4.7 branch, build 4.7.3, as CoreOS 1122.3.0 is using Linux kernel 4.7.0.
