CVE-2023-33870

Local privilege escalation via inherited installer permissions

Published Feb 14, 2024 · Updated Aug 9, 2024

Insecure inherited permissions in Intel Ethernet tools and driver installation software before 28.2 allow local users to escalate privileges. Intel identifies inherited installer permissions but has not disclosed the affected files, permission entries, or privileged operation. Exploitation requires existing local access, low privileges, high-complexity conditions, and user interaction; success grants elevated privileges.
