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
What happened
ETH Zurich researchers discovered a 100% success rate vulnerability in AMD EPYC that allows memory read access via Infinity Fabric. The exploit bypasses SEV-SNP confidential computing protections without physical access or code execution. Bearish impact on AMD EPYC demand as cloud providers reassess security trust.
