CVE-2024-45777
Date: February 19, 2025
A flaw was found in grub2. The calculation of the translation buffer when reading a language .mo file in grub_gettext_getstr_from_position() may overflow leading to a Out-of-bound write. This may be leveraged by an attacker to overwrite senstive grub2's heap data, eventually leading to the circumvention of secure boot protections
