content: Hard to say, its not mentioned in the article or the scientific paper linked in it, so this is speculation based off my personal understanding of the paper. Yes, ddr2 is likely vulnerable, but the risk on ddr2 modules is likely significantly lower, for a couple of reasons.   This is a problem caused by the increased density of memory. Ddr2 squeezes less memory into the same area.   You need a decent amount of free space to make this work, they suggest 2mb of adjacent free space Certainly not impossible, but considering the last ddr2 stick I bought was 256mb, it seems like having that is a lot less likely.   Ddr2 is slower, and you need many memory cycles to take advantage of this, so you can't make it as efficient.   While they demonstrated that his is possible on 32 bit, they note that it takes significantly more work to do so. Now, not all ddr2 machines are 32 bit, but if I had to guess, I'd say that almost all machines with ddr2 either employ ecc (so they are an outdated server), or are long outdated office machines stuck on 32bit. As it shows, all you can do with ecc is cause system instability, not more pressing concerns like privilege elevation.
