The kernel CNA provides NO "score" as that obviously is impossible to do
given that we do NOT know your use case.

What exactly are you trying to do here? Backport random changes to
older kernels for what reason? We are glad to take backports for fixes
that did not apply to older kernels, but you have to test them and
provide a reason for why they should be included. To not have that on
your side already feels very odd.

You have read the in-kernel documentation about how we handle CVEs,
right? It's listed there :)
