漏洞描述
中文描述:
AMD Embedded Processors等都是美国超威半导体（AMD）公司的产品。AMD Embedded Processors是一系列嵌入式高性能 GPU。AMD Client Processor是面向客户端设备（如个人电脑、笔记本电脑等）的处理器。AMD Server Processor是面向服务器市场的处理器产品，主要用于数据中心、云计算、高性能计算等领域。 AMD多款产品存在安全漏洞，该漏洞源于加载CPU微码补丁后清理不完整，可能导致特权攻击者降低RDRAND指令的熵，影响SEV-SNP客户端的完整性。以下产品及版本受到影响：AMD Client Processor、AMD Server Processor和AMD Embedded Processors。
英文描述:
Incomplete cleanup after loading a CPU microcode patch may allow a privileged attacker to degrade the entropy of the RDRAND instruction, potentially resulting in loss of integrity for SEV-SNP guests.
