“Something has gone seriously wrong,” dual-boot systems warn after Microsoft update
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.

"secure" boot, the industry standard for ensuring that devices don't run software other than Windows during the bootup process
FTFY
Nah, you can enroll your own keys and set it up so you can be reasonably certain that your boot image hasn't been altered, validating its integrity against the potential threat of bootkits. I do this with my Gentoo install.
