In the layered architecture of modern computing, security has long been imagined as a series of walls built ever closer to the data — yet Christopher Domas has demonstrated that a door left open at the foundation can render every wall above it meaningless. By manipulating the memory controller's translation registers on AMD Family 14h–16h processors, an attacker with kernel access can silently redirect memory operations into regions — hypervisor tables, firmware stores, security processor enclaves — that the entire platform assumes are unreachable. This is not a misconfiguration or a software
