CVE-2022-40196

Local privilege escalation via undisclosed access-control flaw

Published Feb 6, 2023 · Updated Jan 27, 2025

Improper access control in Intel oneAPI DPC++/C++ before 2022.2.1 and C++ Classic before 2021.7.1 allows local users to escalate privileges. Intel has not published the affected component, the incorrect access-control operation, or the attacker-controlled input involved. A low-privileged authenticated local account is required; successful exploitation crosses a security boundary and grants higher privileges.
