I'm not super familiar with Red Hat, but can someone do a sanity check for me? The recommended mitigation for DirtyFrag is to add the relevant modules to a modprobe blocklist. But...I wasn't aware the modules were loaded dynamically? At least on Fedora, they were not.
I very much want to be wrong about this. And expect I am, but want to be sure.
