LGTM, however, can we keep it under availability vulnerabilities?

@StanFromIreland do you mean keeping it in the previous paragraph?
Suggested change
We can do that, but I think it reads better when it's separate.

I'm +1 for keeping it together, it goes naturally with "Vulnerabilities that affect availability" but I'll leave it up to you.

This is mostly word nitpicking, but: by "crash" we generally mean a segfault or similar; see
Lib/test/crashersfor example.Unhandled exceptions are not crashes, and are not a security concern.
However, since segfaults usually can be weaponized, a “crash resulting from unhandled exception” would be a PSRT issue.
