Windows Update and dual booting linux

From George at Clug@21:1/5 to All on Tue Aug 27 15:40:01 2024

Hi,

I noticed the below issue today.

I think it only affects certain configuration of dual booting so not
too many people should be affected.

Does anyone know of people who have been affected?

Distributions including Ubuntu, Debian, Linux Mint, Zorin OS, and
Puppy Linux have all been affected by Microsoft’s patch.

Microsoft has been using Secure Boot in Windows for years, and made it
a key requirement for Windows 11 [1] to use the technology to secure
against BIOS rootkits. Researchers have found plenty of
vulnerabilities in Secure Boot over the years, and recently it was
discovered that Secure Boot is completely broken on many PCs [2].

George.
