Vulnerability Description
In Lenovo systems, SMM BIOS Write Protection is used to prevent writes to SPI Flash. While this provides sufficient protection, an additional layer of protection is provided by SPI Protected Range Registers (PRx). After resuming from S3 sleep mode in various versions of BIOS for some Lenovo ThinkPad systems, the PRx is not set. This does not impact the SMM BIOS Write Protection, which keeps systems protected.

Lenovo 安全漏洞
Vulnerability Description
Lenovo ThinkPad是联想（Lenovo）的一个便携式计算机。 在Lenovo系统中，SMM BIOS Write Protection用于防止写入SPI Flash。尽管这提供了足够的保护，但SPI保护范围寄存器（PRx）提供了额外的保护层。在某些Lenovo ThinkPad系统版本的BIOS中从S3睡眠模式恢复后，并未设置PRx。这会影响SMM BIOS Write Protection，从而导致系统不受保护。
