DRAM Address Scrambling and the Layer Beneath a Security Boundary — What Happens When the Fence Sits Above the Translation
A research tool was published that reads the most hidden memory regions inside a CPU by perturbing address translation in the DRAM controller. The vulnerability is not in any cipher or permission check. It is in the layo
