I understand--we are also not keen on the way grsec distributes their patches or the timeliness with which they follow stable/LTS kernel releases.
In this case, I can't conceive of a way to reproduce the problem with an upstream kernel or any other, yet to my limited understanding of the evidence it appears there may indeed be a real problem lurking in there.
I will follow up with the grsec folks.
