AMD SEV-SNP Breached: How Firmware Misconfiguration Enables Memory Attacks

The Fabricked attack fundamentally undermines AMD SEV-SNP by exploiting untrusted UEFI's control over memory routing through Infinity Fabric. As confidential computing becomes critical infrastructure for cloud providers, this research reveals that even hardware-based trusted execution environments remain vulnerable to firmware-level attacks. The discovery demands urgent attention to securing the hardware-firmware boundary in confidential computing deployments.
