Quoting from the README.md on the repo:

In other words, the publication of this information was done in consultation with, and at the request of, the kernel and distro security groups - not something that deserves to be called "stupidity". Particularly given there's a pretty simple mitigation (blacklisting and removing the vulnerable modules).
