Intel Chips Have Memory Access Design Flaw and Fix Could Lead to Performance Drop
Wednesday January 3, 2018. 03:27 AM , from MacRumors
A serious design flaw and security vulnerability has been discovered in Intel's CPUs that will require an update at the operating system level to fix, reports The Register. All modern computers with Intel chips from the last 10 years appear to be affected, including those running Windows, Linux, and macOS.
Similar operating systems, such as Apple's 64-bit macOS, will also need to be updated - the flaw is in the Intel x86 hardware, and it appears a microcode update can't address it. It has to be fixed in software at the OS level, or go buy a new processor without the design blunder.Full details on the vulnerability aren't yet known as the information is currently under embargo until later in the month. The Register has unearthed some data, however, and it seems the bug allows normal user programs to see some of the contents of the protected kernel memory.
It's not yet clear how Macs will be impacted, as there is little information available at this time. Software updates are in the works for Linux and Windows, and though not mentioned, Apple is also likely working on a fix for the issue.
Full details on what's known about the vulnerability can be found at The Register, and additional information will be available later this month when complete details on the design flaw are shared.Tag: IntelDiscuss this article in our forums
