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
Researchers at ETH Zurich have revealed a vulnerability in AMD's Infinity Fabric that compromises hardware security protections. This flaw, known as 'Fabricked', allows malicious cloud hosts to access confidential virtual machine memory and manipulate attestation reports. The exploit operates without requiring physical access or code execution within the victim VM.
- ▪The vulnerability undermines AMD SEV-SNP confidential computing protections on EPYC platforms.
- ▪Fabricked exploits flaws in memory routing during boot, enabling unauthorized access to protected VM memory.
- ▪The exploit has a 100% success rate and does not require physical access to the victim's environment.
