AMD EPYC是美国超威半导体（AMD）公司的一款高性能服务器处理器。 AMD EPYC™ 9005 Series Processors和AMD EPYC™ Embedded 9005 Series Processors存在安全漏洞，该漏洞源于对分段反向映射表与系统管理模式内存重叠处理不当，可能导致特权攻击者损坏或部分推断SMM内存，进而造成完整性或机密性丢失。
Description (English)
AMD EPYC is a high-performance server processor for the U.S. Supermassive Semiconductor (AMD). AMD EPYCTM 905 Series Officers and AMD EPYCTM Embeded 905 Series Officers have a security loophole, which stems from an inadequate treatment of the internal memory of the branch map and the system management model, which may lead to damage to or partial extrapolation of the SMM memory by the privileged attacker, resulting in a loss of integrity or confidentiality.
