Second paragraph in the description of patch #21:

These patches have been in use by RHEL and Fedora kernels for years,
and so have been thoroughly tested.

Any module for which the kernel has a key, but which proves to have a
signature mismatch will not be permitted to load (returning
EKEYREJECTED).
