Vulnerability Title
N/A
Source: NVD (National Vulnerability Database)
Vulnerability Description
The Linux kernel before 2.6.16.9 and the FreeBSD kernel, when running on AMD64 and other 7th and 8th generation AuthenticAMD processors, only save/restore the FOP, FIP, and FDP x87 registers in FXSAVE/FXRSTOR when an exception is pending, which allows one process to determine portions of the state of floating point instructions of other processes, which can be leveraged to obtain sensitive information such as cryptographic keys. NOTE: this is the documented behavior of AMD64 processors, but it is inconsistent with Intel processors in a security-relevant fashion that was not addressed by the kernels.

多家厂商AMD CPU本地FPU信息泄露漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
AMD是全球领先的微处理器解决方案供应商，提供各种微处理器解决方案。 在AMD所生产的第7代和第8代处理器上，除非将x87状态字中的异常摘要(ES)位设置为1，否则fxsave和fxrstor指令不会保存FOP、FIP和FDP寄存器指示出现了无掩码x87异常。 这种行为与AMD提供的文档所述是一致的，但与其他厂商的处理器不一致。其他厂商的处理器无论ES位设置为何值都会保存FOP、FIP和FDP寄存器。由于这种差异，在环境切换时无法恢复FOP、FIP和FDP寄存器的内容。 在受影响的处理器上，本地攻击者可以
