A group of academics from KU Leuven and the University of Birmingham has demonstrated a new vulnerability called Battering RAM to bypass the latest defenses on Intel and AMD cloud processors. However, defending against Battering RAM would require a fundamental redesign of memory encryption itself, the researchers noted. "Battering RAM exposes the fundamental limits of the scalable memory encryption designs currently used by Intel and AMD, which omit cryptographic freshness checks in favor of larger protected memory sizes," they added. "Battering RAM [...] is capable of introducing memory aliases dynamically at runtime. As a result, Battering RAM can circumvent Intel's and AMD's boot-time alias checks."
