Threats Tagged 'cve-2026-20885'

CVE-2026-20885 is an improper authentication vulnerability in the Intel TDX module on some Intel platforms operating within Ring 0 Trust Domain. It may allow a system software adversary with privileged user access and high attack complexity to escalate privileges and cause information disclosure. The vulnerability requires local access, no user interaction, and no special internal knowledge. It impacts confidentiality and integrity with no availability impact.

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.
