Intel CPU 存在安全漏洞的安全警告 - 2017

Intel CPU 的安全性漏洞發布,不過... 目前還沒看到 Linux 該怎麼 patch (某些大廠於 Windows 有出 Patch)

Patch 過 BIOS、firmware (韌體)... 還沒 Patch 過 CPU,也不知道 CPU 的漏洞該怎麼玩,先紀錄如何查看是否有漏洞的方式就好。

Intel CPU 存在安全漏洞的安全警告 - 2017

Intel CPU 的漏洞,沒補過,不知道該怎麼補,總是一個新的嘗試,先看看新聞:

Intel CPU 偵測是否有漏洞的工具 與 韌體更新

Intel SA-00086 的偵測工具與韌體

  1. 下載 Intel-SA-00086 偵測工具
