Comment on New ZenHammer memory attack impacts AMD Zen CPUs
Tobberone@lemm.ee 3 months agoAnd unlike the rowhammer report which came a few years ago, neither AM4 nor AM5 is reported at 100% success rate, which asks the question why? What made those specific systems vulnerable?

It might just come down to timing issues. They did mention that one reason DDR5 is so hard to attack is that the time window for flipping a bit is impractically short.
