It was a bad week for processors. Three teams independently discovered the Meltdown attack, and two teams discovered the Spectre attack. Google’s Project Zero has a great writeup on these major vulnerabilities with Intel, AMD, and ARM processors. Intel has responded to the security findings, which The Register has found will lead to as much as a 30% slowdown for older computers. Read more about the design flaw ‘at the heart of Intel CPUs’ or read Linus Torvalds’s thoughts on the situation. By the way, some people saw it coming. For an overview of the past couple days take a look at Peter Brights article on Ars Technica. For a chuckle, read some kernel code submitted by AMD in the aftermath.
