CVE-2024-31157

Privileged information disclosure via OutOfBandXML initialization

Published Feb 12, 2025 · Updated Nov 3, 2025

Improper initialization in the OutOfBandXML UEFI firmware module in some Intel processors allows local users to disclose information. Intel has not disclosed which state remains uninitialized or how the OutOfBandXML module exposes data from that state. Exploitation requires high privileges, local access, high complexity, and specific execution conditions; the reported consequence is information disclosure only.
