Mitigating Copy Fail CVE-2026-31431

Is anyone aware of gotchas when mitigating Copy Fail CVE-2026-31431 [lwn.net, arstechnica.com, theregister.com] with

# echo "install algif_aead /bin/false" > /etc/modprobe.d/disable-algif.conf
# rmmod algif_aead

as detailed on the researchers’ site, or

# grubby --update-kernel=ALL --args="initcall_blacklist=algif_aead_init"

which Red Hat recommends here?
