DRAM Rowhammer "bug"


Basically, it looks like google has found a way to make bits kindof "leak" into places where they shouldnt be.

I was wondering if someone with more knowledge of how DRAM/Phsics works than me was around here, and could comment on whether ECC would help or not, the post mentions ECC may be hiding bit flips, but maybe all you would have to do is flip 2 bits and then the ECC would be defunct?

from what I've read it does seem to be a bigger problem with LP and LV ram. Hopefully DDR4 doesn't make it into a "real" problem.

Edit: it would be cool if someone with some programming-fu wrote a tool to test this, would it be as simple as spam writing a memory address and then reading the adjacent ones to see if they changed?
