MediumMetricsAV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions
Grub2 (affected versions not specified)
Description
A flaw was found in command/gpg, where hooks created by loaded modules are not removed when the related module is unloaded. This allows an attacker to force Grub2 to call the hooks once the module that registered it was unloaded, leading to a use-after-free vulnerability. If correctly exploited, this vulnerability may result in arbitrary code execution, eventually allowing the attacker to bypass secure boot protections.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
