CVE-2021-0106

Local privilege escalation via incorrect default permissions

Published Jun 9, 2021 · Updated Aug 3, 2024

Incorrect default permissions in Intel Optane DCPM software before 2.00.00.3842 or 1.00.00.3515 allow local users to escalate privileges. Intel has not disclosed the affected file, object, or ACL, only that the software assigns overly broad permissions by default. Exploitation requires local authenticated access, high attack complexity, and user interaction, and successful abuse grants elevated privileges.
