CVE-2023-29162

Local privilege escalation

Published Feb 14, 2024 · Updated Mar 20, 2025

Improper buffer restrictions in Intel C++ Compiler Classic before 2021.8 allow local users with high privileges to escalate privileges. The compiler is included in affected Intel oneAPI Toolkits before 2022.3.1, but Intel has not disclosed the affected buffer or unsafe operation. Exploitation requires local access, high privileges, and high complexity; success can expose or alter data and cause limited service interruption.
