Privilege escalation via unsafe dispatcher directory switching
Published Feb 12, 2025 · Updated Feb 13, 2025
Uncontrolled search path in Intel oneAPI Video Processing Library before 2023.4.0 allows local users to escalate privileges. The dispatcher calls SetCurrentDirectory unsafely during MFXEnumImplementations, enabling library resolution through an attacker-influenced search location. Exploitation requires low-privileged local access, user interaction, and control of a searched location; loaded code inherits the application's privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
