Title: 多个产品SMM本地代码执行漏洞

Description:

System Management Mode (SMM)是x86处理器上最高权限执行模式。

多个BIOS实现中允许SMM功能调用SMRAM之外的内存位置，能够访问物理内存的攻击者先破坏SMM调用的函数指针或功能，然后在SMI命令端口0xb2写操作，触发SMM，在SMM上下文中执行任意代码。

Summary

The System Management Mode (SMM) implementation in Dell Latitude E6430 BIOS Revision A09, HP EliteBook 850 G1 BIOS revision L71 Ver. 01.09, and possibly other BIOS implementations does not ensure that function calls operate on SMRAM memory locations, which allows local users to bypass the Secure Boot protection mechanism and gain privileges by leveraging write access to physical memory.
