Security researcher Christopher Domas has released a proof-of-concept project called “skitter-creek-bath-salts,” which demonstrates a vulnerability in AMD’s DRAM-controller configuration that could compromise hardware-enforced memory isolation. This technique, tested on AMD Family 16h processors, manipulates address-translation behavior in the memory-controller layer, allowing access to data typically protected from the operating system, the kernel, and even ring-0 […]
