CVE-2024-21857

Local privilege escalation via uncontrolled search path

Published Aug 14, 2024 · Updated Aug 14, 2024

Uncontrolled search path in Intel oneAPI DPC++/C++ Compiler before 2024.1 allows local users to escalate privileges. Intel has not disclosed which compiler component searches an attacker-influenced path or what privileged executable or library it loads. Exploitation requires low-privileged local access, high attack complexity, and active user interaction, and can compromise host confidentiality, integrity, and availability.
