AMD 官方确认，部分 EPYC 和 Ryzen 处理器存在一个名为“Sinkclose”的新漏洞，代码为“CVE-2023-31315”。
以下EPYC处理器会受影响：
1st Gen AMD EPYC™ Processors formerly codenamed "Naples"
2nd Gen AMD EPYC™ Processors formerly codenamed "Rome"
3rd Gen AMD EPYC™ Processors formerly codenamed “Milan" and “Milan-X”
4th Gen AMD EPYC™ Processors formerly codenamed "Genoa", “Genoa-X”, “Bergamo”, and “Siena”
以下桌面处理器会受影响：
Ryzen™ 3000 (Matisse)：没有修复计划；
Ryzen™ 4000 Series Desktop Processors with Radeon™ Graphics(Renoir) ComboAM4v2PI 1.2.0.cb (2024-07-30) 已经修复
Ryzen™ 5000 (Vermeer)： ComboAM4v2PI 1.2.0.cb (2024-07-30) 已经修复
Ryzen™ 5000 Series Desktop processor with Radeon™ Graphics (Cezanne)：ComboAM4v2PI 1.2.0.cb (2024-07-30) 已经修复
Ryzen™ 7000 Series Desktop Processors(Raphael)：ComboAM5PI 1.2.0.1(2024-08-07)已经修复
Ryzen™ 8000 Series Processors with Radeon™ Graphics(Phoenix) ComboAM5PI 1.2.0.1(2024-08-07)已经修复
具体全貌可以看表格：

当前该漏洞需要内核级访问权限才能充分利用，影响相对较小。但对于已经遭受到该漏洞攻击的机器，影响极大，且难以修复。
参考：The issue is so severe that, in some cases, it may be easier to abandon an infected machine than to repair it, reports Wired.
目前尚不清楚AMD的修复方案是否会影响性能。
