Privileged information disclosure via unverified hypervisor data
Published Aug 11, 2026 · Updated Aug 11, 2026
Information disclosure in Intel TDX module 1.5.24 and earlier and 2.0.14 and earlier allows local users to cause data exposure. The module insufficiently verifies data authenticity in the Ring 0 hypervisor context, but Intel has not disclosed the affected data path or verification operation. Exploitation requires privileged system-software access, high attack complexity, and additional attack requirements; it exposes data without interrupting service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
