Fabricked flaw bypasses AMD EPYC security, exposing VM memory

Researchers have discovered a software-only vulnerability named "Fabricked" that bypasses AMD's SEV-SNP confidential computing protections on EPYC processors. The exploit targets the Infinity Fabric interconnect during the boot process, allowing malicious cloud hosts to gain unauthorized read and write access to virtual machine memory. This flaw also enables the forging of attestation reports, undermining the trust tenants place in their cloud environments. AI
