Exploit grants hardware-level control over older AMD CPUs

A newly discovered exploit, dubbed Skitter Creek Bath Salts (Skitter), allows for hardware-level control over certain AMD CPUs from 2011-2015. Developed by hacker Christopher Domas, the exploit leverages a single instruction to disable memory mapping, granting access to sensitive areas like the Platform Security Processor (PSP), microcode, and System Management Mode (SMM). While requiring kernel-level access to initiate, the exploit effectively bypasses security protections by manipulating the CPU's bank interleaving feature, known as BankSwizzleMode. AI
