RMPocalypse: How a Catch-22 Breaks AMD SEV-SNP

This paper presents RMPocalypse, a novel attack that shows a critical gap in the security of RMP initialization, wherein the x86 cores maliciously control parts of the initial RMP state. The analysis shows that the vulnerability arises due to the complex, but insufficient, interplay of multiple...
