An anonymous reader quotes a report from TechCrunch: In a blog post published minutes ago, Google's Security team announced what they have done to protect Google Cloud customers against the Chip vulnerability announced earlier today. They also indicated their Project Zero team discovered this vulnerability last year (although they weren't specific with the timing). The company stated that it informed the chip makers of the issue, which is caused by a process known as "speculative execution." This is an advanced technique that enables the chip to essentially guess what instructions might logically be coming next to speed up execution. Unfortunately, that capability is vulnerable to malicious actors who could access critical information stored in memory, including encryption keys and passwords. According to Google, this affects all chip makers, including those from AMD, ARM and Intel (although AMD has denied they are vulnerable). In a blog post, Intel denied the vulnerability was confined to their chips, as had been reported by some outlets. The Google Security team wrote that they began taking steps to protect Google services from the flaw as soon as they learned about it.
