CVE-2025-20012

Physical-access information disclosure

Published May 13, 2025 · Updated Nov 3, 2025

Incorrect behavior order in Intel Core Ultra Processors allows physically proximate attackers to disclose information via physical access. Intel identifies the affected locus only as processor hardware and has not disclosed which operations execute out of order or how crafted physical interaction exposes data. Exploitation requires physical proximity, high attack complexity, and no prior privileges or user interaction; confidentiality is affected without reported integrity or availability impact.
