You've completely missed the point, which is very very simply, that if there are known security implications regarding a bug, people want to know. We're not talking about putting a risk factor score against every bug so people can weight up how much of a security threat every bug is, that'd quite obviously get silly. We're not talking about studying all the bugs scientifically so we know what the effects and interactions with others are, that would be more work than fixing the things! But, when there already /is/ knowledge about a *specific* bug having security implications, then people want that knowledge shared.
When the e1000 bug hit that bricked peoples network cards, everyone knew about it, which was the responsible thing to do, so people with that card could avoid those releases. Does that mean people expect all bugs to be released with a "chances of destroying your hardware:" score? No. We're talking about sharing any known information. If the information isn't known, then it is outside of the scope of the discussion of what is being asked for.
