CVE-2022-21216

Privilege escalation via insufficiently granular access controls

Published Feb 16, 2023 · Updated Feb 13, 2025

Access-control failure in out-of-band management on affected Intel Atom and Xeon Scalable Processors allows attackers to escalate privileges. Intel identifies insufficient access-control granularity but has not disclosed the affected operation or authorization decision. Exploitation requires existing high privileges and adjacent-network access; the resulting management privileges and their precise scope remain undisclosed.
