Problems on Dual-Boot systems after Windows updates

On Tuesday, many Linux users installed alongside Windows began reporting that their devices could not boot. They saw an error message that included the phrase: “Something went very wrong.” from Something has gone seriously wrong. latest windows update problems

Cause: an update released by Microsoft as part of monthly security updates. It was intended to close a 2-year-old security hole in GRUB, an open-source bootloader used to boot many Linux distributions

The vulnerability, rated 8,6 out of 10, allowed attackers to bypass secure boot, the industry standard that ensures devices running Windows or other operating systems do not load malicious firmware or software during the boot process.

The vulnerability was discovered in 2022, but for unknown reasons, Microsoft patched it only last Tuesday.

With Microsoft remaining radio silent, those affected by the bug were forced to come up with their own solutions.

One option is to access the EFI panel and disable secure boot. Depending on the user's security needs, this option is not the most secure. A better short-term solution is to delete the SBAT that Microsoft pushed on your computer last Tuesday.

This means that you will still be using secure boot but will be vulnerable to attacks that exploit it CVE-2022-2601.

The steps for the second way are described here

  1. It's not the only one causing problems!! One more thing is the version: КВ5041585 Build:22631.4037 does not allow Speccy to check the temperatures of the CPU and the Socket !! When we have a car, we love it, we adore it and we take care of it, don't rev the engine too much, make sure the fuel is in good condition and that the temperatures don't rise!! Likewise our computer, we have to pay attention to what it is doing behind Othoni and to know at all times what is creating a problem for us, when it appears, that is why I give importance to the control tools I have installed, so I made sure that before Update KB5041585 my Temperatures they were perfect, for example picture 1:

    As you understand, I Uninstalled KB5041585
    and now everything is fine, if they fix it remains to be seen in the future, because Microsoft ordered us to install it because a new version is coming that will remove the bypass of TMP 2 and the CPU if it is the right one, let's build a new computer as if we're running out of money!!
    Anyway, it's not the only thing that's embarrassing if we think about the Censorship that has entered YouTube itself, which isn't just censorship, but that they don't like it and it's a nuisance, they say it has hate speech, etc. They threw me 2 videos like this and on the third one it says... !! hahahaha bourgeois to say……………..
    Thanks for your patience in reading me
