CVE-2026-40693
Published:November 10, 2026
Updated:November 11, 2026
Improper input validation for some Intel(R) TDX Workload Attestation software within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
