CWE ID Description
CWE-416 The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Impact Analysis

The impact of this vulnerability is primarily a potential loss of integrity. A malicious hypervisor exploiting this flaw could cause a migrated guest VM to run on an unintended CPU socket, which might compromise the integrity of the virtualized environment.

Executive Summary

This vulnerability is a use after free issue in the SEV firmware. It allows a malicious hypervisor to activate a migrated guest virtual machine with the SINGLE_SOCKET policy on a different CPU socket than the migration agent. This mismatch can potentially lead to a loss of integrity in the system.
