What is CVE-2025-31356?
CVE-2025-31356 is a medium-severity vulnerability in Intel(R) Trust Domain Extensions (Intel(R) TDX), published on 11 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
Insufficient verification of data authenticity for some Intel(R) Trust Domain Extensions (Intel(R) TDX) within Ring 0: Hypervisor may allow an information disclosure. A system software adversary with a privileged user access combined with a high complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are present without any user interaction. The potential vulnerability may impact the confidentiality (high), integrity (low) and no effect on availability. Subsequent system impacts include reduced confidentiality (low), integrity (low), and no effect on availability.
Weakness: CWE-345
