Local information disclosure via coarse access controls
Published Aug 11, 2026 · Updated Aug 11, 2026
Information disclosure in some Intel Xeon 6 processors with Intel TDX allows local users to expose protected system data. An undisclosed processor subsystem applies access controls at insufficient granularity, permitting data exposure across a boundary Intel has not identified publicly. Exploitation requires authenticated low-privileged access, high attack complexity, special internal knowledge, and a TDX-enabled affected processor; no user interaction is required.

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.
