AMD 悄然移除 CPU 内存加密功能，用户面临风险

作者 PulseAugur 编辑部 · [1 个来源] · 2026-06-17 10:00

据报道，AMD 已在未事先通知的情况下从其消费级 Ryzen CPU 中移除了透明安全内存加密 (TSME) 功能。这项安全功能此前可在低端芯片上使用，用于加密内存数据以防止物理攻击，但现在 AMD 官方声明该功能仅限于其 PRO Technologies 产品线。在 Windows 上移除此功能难以察觉，在 Linux 上则需要技术手段才能检测，导致许多用户对这一变更毫不知情。移除的确切原因尚不清楚，有猜测认为这可能是故意的政策调整，也可能是最新 AGESA 固件中的无意回归错误。 AI

AMD silently removes memory encryption from consumer Ryzen CPUs, leaving users unaware that they may be vulnerable — security feature vanishes after newer AGESA firmware, AMD engineers go radio silent when pressed about the change

AMD has reportedly stripped TSME from consumer Ryzen processors after years of working support, with testing suggesting newer AGESA firmware disables the memory-encryption feature while Pro and EPYC CPUs remain unaffected.
