Dan Goodin / Ars Technica:
Researchers say they used a new Rowhammer exploit to successfully flip bits on all 40 PC-DDR4 DRAM devices they tested, defeating recent hardware mitigations  —  Researchers build “fuzzer” that supercharges potentially serious bitflipping exploits.  —  Rowhammer exploits that allow unprivileged attackers …
