stop-zenbleed-win

在 Windows 上阻止 Zenbleed（CVE-2023-20593） 新发现的 Zenbleed 漏洞（CVE-2023-20593）影响所有 AMD Zen2 处理器。 不幸的是，AMD 要到 2023 年 11 月或 12 月才会为其许多处理器提供微码更新。 在此期间如何保持安全？ 幸运的是，存在一种软件规避方案。 虽然在 Linux 上应用软件规避方案只需一行命令，但在 Windows 上情况更为复杂。 要应用软件规避方案，需要在 MSR CPU 寄存器中设置一个特定的位（chicken bit DECFG9）。 正如 Travis Ormandy 指出的，以下命令可用于在...
