Any system where you do not have 100% trust in your users, their
passwords and the devices they use will (IMHO) need to be patched.

But as ever this will need to be a site-specific risk assessment.

For sites running Slurm with Munge they might want to consider what
the impact of a user being able to read the munge secret key out of
memory and potentially reusing it, for instance.

All the best,
