CVE-2023-33874

Local privilege escalation via uncontrolled installer search path

Published Nov 14, 2023 · Updated Aug 30, 2024

Uncontrolled search path in Intel HID Event Filter Driver installers before 2.2.2.1 allows local users to gain elevated privileges. The published record identifies the installation software as the affected locus but does not disclose the executable, load target, or search order responsible. Exploitation requires low-privileged local access, user interaction, and a compatible NUC12WS system; successful execution obtains the installer's elevated privileges.
