CVE-2025-35972

Local privilege escalation via uncontrolled search path

Published Nov 11, 2025 · Updated Nov 11, 2025

Uncontrolled search path in Intel MPI Library for Windows before 2021.16 allows local users to escalate privileges. Intel has not disclosed which executable, library lookup, or search-path input resolves attacker-controlled content ahead of the intended component. Exploitation requires an authenticated low-privileged local user, high complexity, attack requirements, and active user interaction, with impact confined to the vulnerable system.
