Microsoft's August security update included a patch to prevent vulnerable GRUB2 (susceptible to bypassing UEFI secure boot) installations from booting.
https://www.omgubuntu.co.uk/2024/08/windows-update-breaking-linux-dualboot-f...
The update was supposed to not install on already-configured dual boot systems, but that apparently failed, so lots of dual-boot systems had their Linux boot blocked after the update.
I wondered if up-to-date Fedora users were affected by this issue. Would like to know before I apply Windows updates whether I will need to deal with it.
TIA for any information, experiences.

Fedora is not affected, I understand, because Fedora patched, about 2 years ago, soon after the security issue was discovered.
Some distributions have not been updating the installed grub which is why those systems were affected.
And as you say Microsoft has a bug in their update that did update the SBAT on some dual boot systems.

Hmm, would they prevent their own system from booting if it had (yet another) security flaw?
Perhaps they should.

There are various kinds of security. Consider that cars these days are basically phones on wheels. Software is updated over the air without the user even being aware. How would you like to own a car with a security flaw that prevented it from starting when you were trying to evacuate from a wildfire?

You're comparing apples and oranges. I was comparing apples and apples, pun intended.
