Vulnerability Details CVE-2026-20885

Improper authentication in the Intel(R) TDX module for some Intel(R) platforms within Ring 0: Trust Domain may allow an information disclosure and escalation of privilege. System software adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. 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 (high), integrity (high) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (low), integrity (low) and availability (none) impacts.
