CVE-2023-32633

Authenticated local privilege escalation

Published Mar 14, 2024 · Updated Nov 4, 2025

Improper input validation in Intel CSME Software Installer before 2328.5.5.0 allows local users to escalate privileges during installation. Intel has not disclosed the affected installer component or the input that is accepted without adequate validation. Exploitation requires low-privileged local access, high attack complexity, and user interaction; successful abuse grants elevated privileges and can compromise system confidentiality, integrity, and availability.
