CVE-2024-2312  (opens in a new tab)

How to fix?

Upgrade Debian:13 grub2 to version 2.12-2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream grub2 package and not the grub2 package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

GRUB2 does not call the module fini functions on exit, leading to Debian/Ubuntu's peimage GRUB2 module leaving UEFI system table hooks after exit. This lead to a use-after-free condition, and could possibly lead to secure boot bypass.
