CVE-2021-33092

Local privilege escalation via insecure installer permissions

Published Nov 17, 2021 · Updated Aug 3, 2024

Incorrect default permissions in the Intel NUC M15 HID Event Filter driver pack before 2.2.1.383 allow local users to escalate privileges. The installer assigns overly permissive defaults, but Intel has not disclosed the affected files, directories, or access-control entries. Exploitation requires low-privileged local access and user interaction, after which elevated privileges can compromise data and system operation.
