Microsoft said its update wouldn't install on Linux devices. It did anyway.

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…

        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: nevermin 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…
