In that case, it's pretty much a random number (of a random page used as a leave page table) and does not let g1 identify locations of symbols etc. If so, I don't think this is a "clear security issue" and suggest squashing this into the actual fix (#p4 I assume).
yeah __maybe__ I overstated the importance ;)
But I would still like to keep it as a separate patch, looks more straightforward to me
I don't see a need to split this up. Just fix it right away.
