CVE-2021-33088

Local privilege escalation via permissive installer defaults

Published Nov 17, 2021 · Updated Aug 3, 2024

Incorrect default permissions in the Intel NUC M15 Laptop Kit ISH Driver Pack before 5.4.1.4449 allow local users to escalate privileges. The installer assigns overly permissive defaults to an undisclosed resource instead of restricting access to the account running installation. Successful exploitation requires an authenticated local user and user interaction, and grants elevated privileges on the affected system.
