The recommended method for undo an update is https://access.redhat.com/solutions/64069, but it's not supported if glibc, kernel, or selinux are changed. I'd give it a try if the system is not critical. Make backups first.
Some other people's experience on downgrading a point release: https://access.redhat.com/discussions/2933711
If you couldn't read that article, just search "yum history undo".
That didn't work unfortunately. The lesson learned here is :
* CR repository works great for servers
* never use it to upgrade a desktop
