漏洞描述

中文描述:

grub2是GNU社区的一款Linux系统引导程序。 GRUB2 2.04及之前版本中存在数据伪造问题漏洞。该漏洞源于当没有shim直接启动时，程序未验证内核签名。攻击者可利用该漏洞绕过安全启动。

英文描述:

GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed. This only affects systems where the kernel signing certificate has been imported directly into the secure boot database and the GRUB image is booted directly without the use of shim. This issue affects GRUB2 version 2.04 and prior versions.

CWE类型:
