PoC Usage This repo contains a VMM that boots an SEV-SNP guest with a custom kernel. The VMM and kernel are a stripped-down version of a project of mine. A modified Linux kernel is required to run on the host: https://github.com/Freax13/linux/tree/for-amd. The Proof of Concept can be run like thi...

New DDRop Attack Breaks Intel TDX and AMD SEV-SNP Confidential Computing
Researchers have disclosed a new hardware attack, called DDRop , that breaks the memory protection in Intel and AMD confidential computing by silently dropping writes to a server's memory, so the processor keeps reading old encrypted data as if it were current. The attack requires an attacker who...
Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15
In the Linux kernel before version 6.9, a trusted-to-non-trusted hypervisor can inject Virtual Interrupt 29 VC at any point in time and can trigger its handler. This affects AMD SEV-SNP and AMD SEV-ES...
