First install the updates and then you will read. And it is that several security flaws have been discovered that are known as ZombieLoad, vulnerabilities that basically allow a malicious user to collect sensitive information from our processor. This sensitive information may include browser history, passwords, and more. The bug has affected devices with an Intel processor since 2011, although Apple assures that its iOS is not affected. If Windows, macOS and the systems that interest us most are affected Linux Adictos, Android and Linux.
Intel has already released an update to its firmware microcode, but this update cannot reach Linux-based operating systems. Systems based on the Linus Torvadls kernel have to wait for companies to release new versions of their kernel to tackle the problem. Among the early risers has been Canonical, who has already made available to Ubuntu users and all its official flavors new versions of your kernel that solve the problem.
ZombieLoad affects Windows, macOS, Android and Linux
It is recommended for almost any user with a device that has an operating system update as soon as possible. The failure is considered so serious that they even recommend restarting the computer after applying the update. I mention this because Canonical recommends it even though its Live Patch has been created just to avoid having to reboot after updating the Ubuntu kernel. It is also recommended to go to the BIOS of the computer and disable SMT (Symmetric Multi-Threading or Hyper-Threading), something that will be different depending on the computer and its BIOS version.
The video above these lines gives us an idea of the severity of the failure. As you can see, a malicious user can know which websites we visit. The moment in which you enter Wikipedia and the terminal appears "Reading about Privacy" is especially striking, since we all tend to search the internet for what interests us or, what is worse, what worries us. So, if you still haven't listened to the first thing I said: UPDATE.
