Technical details
Improper resource reuse in SEV firmware allows an attacker with hypervisor-level access to write to the Reverse Map Table (RMP), which protects encrypted guest memory from unauthorized modifications. The vulnerability requires existing hypervisor access and results in loss of guest memory integrity. No public exploit is known.
