English(EN) Researchers attack AMD's Infinity Fabric to bypass hardware security protections with 'Fabricked' — flaw lets malicious cloud hosts silently read confidential VM memory and forge attestation reports

Fabricked 漏洞绕过 AMD EPYC 安全，暴露虚拟机内存

作者 PulseAugur 编辑部 · [2 个来源] ·

研究人员发现了一个名为“Fabricked”的纯软件漏洞，该漏洞可以绕过 EPYC 处理器上 AMD 的 SEV-SNP 机密计算保护。该漏洞利用了启动过程中的 Infinity Fabric 互连，允许恶意云主机获得对虚拟机内存的未经授权的读写访问。此漏洞还能够伪造证明报告，从而破坏租户对其云环境的信任。 AI

影响 破坏了依赖硬件级安全进行机密计算的云环境的信任。

排序理由 研究人员披露了一个影响 AMD 硬件安全保护的纯软件漏洞。
