CVE-2024-2312  (opens in a new tab)

How to fix?

Upgrade SLES:15.7 shim to version 16.1-150300.4.31.3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream shim package and not the shim package as distributed by SLES. See How to fix? for SLES:15.7 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.
