CVE-2022-26076

Local privilege escalation via uncontrolled search path

Published Feb 16, 2023 · Updated Jan 27, 2025

Uncontrolled search path handling in Intel oneDNN before 2022.1 allows local users to escalate privileges through local access. Intel identifies an uncontrolled search path element but has not disclosed the affected loader, path, or lookup operation. Exploitation requires low-privileged local access and user interaction, and successful abuse can execute attacker-controlled code with elevated privileges.
