CVE-2024-45777: GNU GRUB2

Medium severity, CVSS 6.7. EPSS: 0.2% chance of exploitation in the next 30 days.

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 issue can be leveraged by an attacker to overwrite grub2's sensitive heap data, eventually leading to the circumvention of secure boot protections.

• Red Hat Enterprise Linux: version 7.0 only; version 8.0 only; version 9.0 only; version 10.0 only
