Ars Technica’s Dan Goodwin writes: Last Tuesday, loads of Linux usersâ”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. […]
With Microsoft maintaining radio silence, those affected by the glitch have been forced to find their own remedies. One option is to access their EFI panel and turn off secure boot. Depending on the security needs of the user, that option may not be acceptable. A better short-term option is to delete the SBAT Microsoft pushed out last Tuesday. This means users will still receive some of the benefits of Secure Boot even if they remain vulnerable to attacks that exploit CVE-2022-2601. The steps for this remedy are outlined here (thanks to manutheeng for the reference).
