Vulnerability from github – Published: 2024-04-05 21:32 – Updated: 2024-04-26 09:30

Details

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 ?

6.7 (Medium)
