CVE-2025-31938 Intel CVE debrief

Who should care

System administrators and security teams responsible for Intel(R) Xeon(R) 6 Scalable processors with Intel(R) TDX should assess and verify exposure to potential information disclosure.

Why it matters

CVE-2025-31938 is a medium-severity vulnerability in Intel(R) Xeon(R) 6 Scalable processors with Intel(R) TDX that may allow information disclosure via local access. System administrators and security teams should assess and verify exposure, review system configurations, and update incident response plans as necessary.

• Verify local access controls and user authentication mechanisms to prevent unauthorized data exposure.
• Assess system configurations to ensure they are up-to-date and secure.
• Review and update incident response plans to address potential information disclosure.

Technical summary

Insufficient granularity of access control in some Intel(R) Xeon(R) 6 Scalable processors with Intel(R) TDX may allow an information disclosure. An authorized adversary with authenticated user access and high complexity attack may enable data exposure via local access with special internal knowledge and no user interaction. The vulnerability affects Intel(R) Xeon(R) 6 Scalable processors with Intel(R) TDX and has a CVSS score of 4.3, indicating medium-severity impact. System administrators and security teams should assess and verify exposure to potential information disclosure.
