CVE-2023-25779

Local privilege escalation via uncontrolled search path

Published Feb 14, 2024 · Updated Aug 16, 2024

Uncontrolled search path in Intel Thunderbolt DCH drivers for Windows before 88 allows local users to elevate privileges. Intel has not disclosed the affected file or function, the searched location, or how an attacker-controlled search-path element is consumed. Exploitation requires low local privileges and user interaction; success grants a higher-privileged security context with expanded access to protected data and system operations.
