Windows上的Meltdown检测方法

寂寞艹无聊

操作系统版本要求：
Windows 10 (RTM, 1511, 1607, 1703, 1709)
Windows 8.1
Windows 7 SP1

安装2018年1月3日的安全更新

然后运行PowerShell
安装PowerShell模块的代码
PS > Install-Module SpeculationControl

运行PowerShell模块，验证保护是否启用
PS > Get-SpeculationControlSettings

会显示如下代码：
PS C:\> Get-SpeculationControlSettings

Speculation control settings for CVE-2017-5715 [branch target injection]

Hardware support for branch target injection mitigation is present: True

Windows OS support for branch target injection mitigation is present: True

Windows OS support for branch target injection mitigation is enabled: True

Speculation control settings for CVE-2017-5754 [rogue data cache load]

Hardware requires kernel VA shadowing: True

Windows OS support for kernel VA shadow is present: True

Windows OS support for kernel VA shadow is enabled: True

Windows OS support for PCID optimization is enabled: True

是True的就代表开启了。


AMD处理器不受Meltdown影响，因此VA shadowing为False



Intel处理器受Meltdown影响，因此需要VA Shadowing
