CVE-2024-2312
Fixed in a distro release EPSS <1%CVSS 6.7
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.
Products: Debian based GNU GRUB, gnu grub2
