CVE-2025-31655

Local privilege escalation via incorrect default permissions

Published Feb 10, 2026 · Updated Feb 10, 2026

Incorrect default permissions in Intel Battery Life Diagnostic Tool before 2.7 allow local users to escalate privileges with active user interaction. Intel identifies the locus only as Ring 3 user applications and does not disclose which installed files or directories receive permissive access controls. Exploitation requires a low-privilege authenticated context, high attack complexity, additional attack requirements, and active user interaction; success grants higher local privileges on the same system.
