aiqbench analysis

MIT researchers have identified a systemic timing vulnerability in Intel and AMD processors that bypasses modern security defenses like saferet. By exploiting the fleeting window between when a chip's prediction machinery is cleared and when it is used, attackers can reliably inject code to extract sensitive data such as Linux password files. This discovery underscores a critical weakness in current hardware security architectures where interrupt mechanisms can be weaponized to contaminate processor predictions across multiple generations of chips.

MIT researchers defeated key security measures in Intel and AMD chips, extracting a Linux password file.

MIT Computer Science and Artificial Intelligence Laboratory researchers demonstrated a new attack that bypasses critical security defenses in processors from both Intel and AMD. The team exploited a fleeting gap between when a chip’s prediction machinery is…
