CVE-2024-21828

Local privilege escalation via undisclosed installer access control

Improper access control in Intel Ethernet administrative tools before 28.3 allows local users to elevate privileges during installation. Intel has not published the affected installer component or the access-control operation it performs incorrectly. Exploitation requires authenticated local access, high attack complexity, and user interaction, and successful exploitation grants elevated privileges.
