Title: Intel CPU Foreshadow-NG（预兆下一代版本）漏洞（CNVD-2018-15494）

Description:

L1终端故障VMM漏洞和CVE-2018-3620一样，属于Foreshadow-NG（预兆下一代版本），同样，其他厂商CPU可能也受到影响，利用推测执行侧信道攻击，具有本地用户访问权限的攻击者可以实现未经授权读取到L1缓存中的数据（包括虚拟主机），从而触发信息泄露效果，可能导致云平台虚拟主机内存信息被未经授权越权读取，同时，针对侧信道攻击早期版本Meltdown（熔断）和Spectre（幽灵）的缓解措施可能对其无效。

Severity: 中

Patch Name: Intel CPU Foreshadow-NG（预兆下一代版本）漏洞（CNVD-2018-15494）的补丁
