It's crazy that the researchers who discovered Copy Fail only worked with the Linux Kernel Organization to patch it in the mainline kernel but didn't work with any of the major distros to make sure a patch was available before disclosing the exploit. Unless you're running a rolling distro, a dev version or a distro with short release windows, it's effectively an unpatched zeroday.

The ones most vulnerable to this are the type of systems that run on long term release kernels, not rolling releases or short release distros like Fedora.

This whole saga is a big clusterfuck for the Linux community to scramble to patch this major flaw.
