alt Hacker NewsThis workaround only applies to kernels with the impacted code compiled as a module. RHEL, Fedora, and Gentoo (we use a modified Fedora config) all are configured to build this in directly. Without a patch or config change (as Sam from Gentoo was alluding to), those distributions remain vulnerable.

This worked as a mitigation on distros with the module compiled into the kernel: https://gist.github.com/m3nu/c19269ef4fd6fa53b03eb388f77464d...
Basically: sudo grubby --update-kernel=ALL --args=initcall_blacklist=algif_aead_init
sudo reboot

F44 is safe as the kernel is greater than 6.18.22
There was some discussion on the GitHub issues about workarounds to disable it, even though it is baked in.
