Exiting grub-efi causes my OVMF virtual machine to crash with the above error.
The #UD likely comes from some global hook not being uninstalled. |
[Impact]
Signed grub2 binaries in Ubuntu Mantic are affected by CVE-2024-2312. Please see details below.
[Test Plan]
Make sure Ubuntu Mantic still boots with the new GRUB.
[Where problems could occur]
Not very likely, Ubuntu Mantic fix is a simple git revert of the faulty change.
