Thanks, I guess you are actually supporting my point, and that is -- there 
is no consensus whatsoever of what assigning a CVE actually means, at all.

To me -- physical damage to the system, fair enough, that might really 
easily be security relevant.

Something being too loud, causing distress ... that's really a grey zone 
(to put it mildly) for me. How about e.g. a bug in GPU driver, leading to 
a flickering screen? Many people are very sensitive to that (both 
physically and mentally) for various reasons.

Bug worth fixing? Absolutely, as soon as possible. Security-relevant? Not 
in my book.

To me, kernel is in no way special, in this respect, actually. With each 
and every coding error in software of your choice, given anough fantasy, 
you'll come up with a scenario where this will cause some real issues to 
some living human.

That's not what CVE is about at all, at least in my understaing.
