CVE-2024-2312 (GCVE-0-2024-2312)

Vulnerability from cvelistv5 – Published: 2024-04-05 19:40 – Updated: 2025-02-13 17:33

Summary

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.

Severity
