Researchers disclosed a critical vulnerability in AMD's Infinity Fabric interconnect that allows malicious cloud hosts to bypass hardware security protections, read confidential VM memory, and forge attestation reports. The attack, dubbed 'Fabricked,' undermines AMD's trusted execution environment guarantees in multi-tenant cloud deployments.
The flaw affects AMD's SEV-SNP isolation model and has implications for enterprises relying on AMD EPYC processors for confidential computing. Patches and mitigation strategies from AMD are expected to address the issue across Genoa and Bergamo generations.
