Frequently Asked Questions

1

Who is exposed to this issue?

SEV-SNP guest environments are exposed if an attacker already has privileged access to the hypervisor. The issue affects guest-memory integrity rather than confidentiality or availability.

2

What access does an attacker need to exploit it?

The attacker needs local access and high privileges, specifically hypervisor access. No user interaction is required.

3

What is the potential impact on an affected guest?

A privileged hypervisor attacker may overwrite SEV-SNP guest memory, causing loss of data integrity.
