Yes, 5.4 will be going end-of-life in December. Right now, with the
5.4.299 kernel release, I count 1419 unfixed CVEs in that release, which
does NOT include the known CPU vulnerabilities that are not fixed in
that branch as well (kernel.org does not assign CPU bug CVEs).
So if I were to just go off of that number, I would think that this was
already an "unsupported" kernel tree, and would never recommend anyone
use it for anything that is exposed to untrusted users.
Anyway, I understand that's not the business model you all are in, and I
wish you the best of luck maintaining that beast for longer periods of
time. Hopefully people are throwing large buckets of cash at you to do
so :)
thanks,
