To clarify so that I’m not responding incompletely, are we seeing all page faults, i.e. process swapped to disk, now raise SIGKILL — or is this behavior reserved only for certain page faults, i.e. out-of-bounds and permission-denied (R^X) accesses?

The former would be a catastrophic defect and probably result in the release being pulled from distribution.

The latter would be a new classification of certain kinds of page faults as “safe” and “unsafe”, and only the safe ones are allowed to comply with POSIX signal handling. Perhaps they’ll propose an update to POSIX now that the zero day response has shipped.
