Severity ?
6.4 (Medium) - CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H
Summary
A flaw was found in command/gpg. In some scenarios, hooks created by loaded modules are not removed when the related module is unloaded. This flaw 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.

Este defecto permite que un atacante obliga a Grub2 llamar a los ganchos una vez que el m\u00f3dulo que lo registr\u00f3 se descarg\u00f3, lo que llev\u00f3 a una vulnerabilidad de use-after-free. Si se explota correctamente, esta vulnerabilidad puede dar como resultado una ejecuci\u00f3n de c\u00f3digo arbitraria, lo que eventualmente permite que el atacante pase por alto las protecciones seguras de arranque."
