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...

SUSE CVE-2026-31628

In the Linux kernel, the following vulnerability has been resolved: x86/CPU: Fix FPDSS on Zen1 Zen1's hardware divider can leave, under certain circumstances, partial results from previous operations. Those results can be leaked by another, attacker thread. Fix that with a chicken bit...

CVE-2026-31628

CVE-2026-31628 concerns the Linux kernel on Zen1 CPUs, where the x86/CPU FPDSS issue could allow a local attacker to leak partial results from prior operations via the hardware divider. Patches fix the vulnerability by applying a kernel change (the “chicken bit”) to prevent leakage. Connected adv...
