Last week, the Intel microcode firmware update officially arrived at the Ubuntu repository to close the system's vulnerabilities using Intel Cherry Trail and Intel Bay Trail processors.
Canonical now releases another update for all supported Ubuntu operating systems to fix hardware bugs in the Intel Sandy Bridge processor family. Canonical said in Security Bulletin:
USN-3977-1 and USN-3977-2 provide targeted fixes for Microarchitecture Data Sampling (MDS) vulnerabilities in Intel Microcode, which provides microcode updates for the Intel Sandy Bridge processor family. .
If your computer is running the following versions of Ubuntu and Intel processors, make this update available now:
Users who are running Ubuntu 19.04 (Disco Dingo), Ubuntu 18.10 (Cosmic Cuttlefish), Ubuntu 18.04 LTS (Bionic Beaver), Ubuntu 16.04 LTS (Xenial Xerus), and Ubuntu 14.04 ESM (Trusty Tahr), if your Intel processor is affected, please update the Intel microcode firmware immediately to version 3.20190618.0.
Also make sure you have the latest Linux kernel for your current Ubuntu Linux distribution to completely reduce the impact of new vulnerabilities.
