Hmm.  It seems that it didn't make it into Linus' tree.  Crap.

IMO we need some kind of real tracking system for issues reported to
security at .  This shouldn't have been possible (and if I'd realized
that the patch got dropped, I wouldn't have publicly disclosed it).

For whoever applies this: it's CVE-2014-3917.
