Intel TDX Modules Privilege Escalation Vulnerability

A race condition vulnerability has been identified in some Intel Trust Domain Extensions (TDX) modules within Ring 0 of the hypervisor. This vulnerability may allow a system software adversary with privileged user access to escalate privileges, potentially leading to unauthorized actions or access. The issue arises from a low complexity attack that can be executed locally, without special internal knowledge or user interaction. The vulnerability has a high impact on the confidentiality and integrity of the affected system.

Impact

Exploitation of this vulnerability could lead to unauthorized privilege escalation, allowing a user to gain elevated rights or access within the system.

Remediation

Intel recommends that users of affected Intel Xeon processors update to the latest version provided by their system manufacturer that addresses this vulnerability.
