Power/Performance Bits: May 21


More speculative vulnerabilities Security researchers at the Graz University of Technology, KU Leuven, Cyberus Technology, and Worcester Polytechnic Institute point to two new speculative execution vulnerabilities related to Meltdown and Spectre. The first, which they dubbed ZombieLoad, uses a similar approach to Meltdown. After preparing tasks in parallel, the processor needs to discard th... » read more

The Week In Review: Design


Security Security researchers identified a major exploit of the "speculative execution" technique used to optimize performance in modern processors. The flaws allow an attacker to read sensitive information in the system's memory such as passwords, encryption keys, or sensitive information open in applications, according to Google's Jann Horn. Multiple researchers discovered the issues indepen... » read more
