Last Tuesday, loads of Linux users—many running packages released as early as this year—started reporting their devices were failing to boot. Instead, they received a cryptic error message that included the phrase: “Something has gone seriously wrong.”
The cause: an update Microsoft issued as part of its monthly patch release. It was intended to close a 2-year-old vulnerability in GRUB, an open source boot loader used to start up many Linux devices. The vulnerability, with a severity rating of 8.6 out of 10, made it possible for hackers to bypass secure boot, the industry standard for ensuring that devices running Windows or other operating systems don’t load malicious firmware or software during the bootup process. CVE-2022-2601 was discovered in 2022, but for unclear reasons, Microsoft patched it only last Tuesday.
…
The reports indicate that multiple distributions, including Debian, Ubuntu, Linux Mint, Zorin OS, Puppy Linux, are all affected. Microsoft has yet to acknowledge the error publicly, explain how it wasn’t detected during testing, or provide technical guidance to those affected. Company representatives didn’t respond to an email seeking answers.
So, no booting into Windows until this is fixed then? Fine by me. Hell, might actually make me uninstall it completely and free some disk space…
Well… It’s the opposite… People affected by this issue could not boot Linux…
Right, but you have to boot into Windows first to even get the update in the first place…
But if you don’t boot Windows first you’ll not be affected by this issue. So my statement is correct
That’s… What the person you replied to said in the first place.

Nice meme, bro!
No, they’re literally saying the same thing
Woah, interesting.
Is that like a legal option because it looks like it doesn’t ask you to provide an image or whatever? Not that I mind either way, just curious if this is prone to be deleted soon or not.What’s the upside of having it in a VM?
Edit: nevermind the legality, found a disclaimer at the bottom of the page.
The upside is you can treat it as just another program with a big flat file that serves as it’s hard disk. You can move a VM between computers, they’re universal. Hell you can move it to a data center and hardly notice a difference. You can make a snapshot, try something out, and if it borks, roll it back to a previous snapshot. You can copy the VM any number of times.
Basically it decouples operating systems from hardware so you can treat a computer like software.
Oh cool! I’ll need to look into that, thanks! Wonder if there’s a way to convert an existing Windows parition into this somehow, installed software and all, because that would be perfect…
Not that I know of, though imaging a physical Windows install to a VM is very possible. I just kinda like the docker solution because it’s fairly lightweight, but if you want a more robust solution, a VM is the way to go. There’s still limitations on both solutions like gaming not really being a thing unless you get deep in the weeds with things like VFIO and Looking Glass.
There is also the option to use two GPUs (or one and not use it for Linux). https://github.com/mr2527/pop_OS-win10-KVM-setup
Yah, that’s the VFIO method I was referring to.
Ah, okey! I saw the guide and thought it looked interesting at first. But then my wallet saw two GPUs and promptly said no.
Why would anyone want to game in a VM?

Hey Microsoft: Windows is yours, GRUB is mine. I don’t give a shit if GRUB is vulnerable, I’ll fix that myself if I choose to.
Mind your own fucking business. The most you should ever do is let me know about it, not try to patch things you aren’t responsible for…
The update was meant to fix a situation where an attacker would somehow get grub onto a machine that was SINGLE booting windows and use grub to tamper with secureboot. this fix was meant to only apply in single boot situations where it should be entirely unexpected to see grub. as they said, something went seriously wrong.
if only there was some way people could test updates before rolling them out to everyone
this here is the real issue.
Preach brother
CVE-2022-2601 was discovered in 2022, but for unclear reasons, Microsoft patched it only last Tuesday.
I respect their journalistic integrity for not speculating, but it was definitely because the NSA was exploiting it.
Ehhh i that’s likely enough, but Microsoft is also just shit at fixing things
That’s what they want you to believe.
No, they really are. No doubt they do plenty of stuff at the behest of the NSA, but they are also a deeply disfunctional company with conflicts between departments and bare minimum funding for security, since it’s seen as a cost centre
I hate to break it to you but why would the NSA need a security hole in secure boot. They already have all your data from Windows plus Microsoft has the decryption keys.
Because some users are putting that data on Linux. So they want Linux to be killed.
They can’t change grub. But they sure as hell can convince micro$org to search for and nuke it.
Of course no idea if this happened. Just answering why they would might want to.
So all afected people were potential targets?
Potential targets? Sir, thats everybody.
