No Red Hat patch yet
Despite the article claiming Red Hat have a patch out, the article link is only to the CVE announcement on Red Hat's site. If you check the Bugzilla bug for it here:
https://bugzilla.redhat.com/show_bug.cgi?id=1384344
You'll see that there isn't actually a patch out yet as of Monday morning UK time. There is a (fiddly) mitigation procedure involving systemtap documented at the above URL, but no new kernel RPM to fix the issue yet. This means that CentOS and other RHEL clones are also unpatched at this moment in time as well.
Biting the hand that feeds IT
