Intel Releases Processor Microcode Patch for Linux OSes, Here’s How to Update

By now, everyone heard about Meltdown and Spectre, two severe hardware bugs that affect billions of devices, putting them at risk of attacks as unprivileged attackers could steal your sensitive data stored in kernel memory using a locally installed application or via the Internet using malicious scripts. Intel, AMD, and ARM processors are affected by these security exploits. Intel promised last week to release updated microcode to address the Meltdown and Spectre bugs, and the patch is finally here, available for numerous of its processors released in the past five years. Users are urged to update the microcode (installation instructions are available below) immediately. The entire list is attached at the end of the article, and Intel has also listed some of the officially supported Linux-based operating systems.
