Privilege escalation via firmware buffer restriction
Published Aug 18, 2022 · Updated Feb 18, 2025
Improper buffer restrictions in Intel NUC Laptop Kits firmware before BC0076 allow remote authenticated users to enable privilege escalation via local access. Firmware buffer-bound enforcement performs an incorrect restriction operation on attacker-influenced data, but Intel has not published the precise routine or input path. A privileged local user is required, and the consequence is escalation of privileges with potential confidentiality, integrity, and availability impact.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
