CVE-2022-21229 is a high-severity vulnerability affecting Intel(R) NUC 9 Extreme Laptop Kit drivers prior to version 2.2.0.22. The root cause is improper buffer restrictions within these drivers, which can be exploited by an authenticated local user to escalate their privileges on the affected system. Specifically, the vulnerability allows a user with limited privileges (local authenticated user) to gain higher privileges, potentially administrative or SYSTEM-level access, by leveraging the flawed buffer handling in the driver code. The vulnerability does not require user interaction beyond authentication and is exploitable locally, meaning an attacker must already have some level of access to the system. The CVSS 3.1 base score of 7.8 reflects the significant impact on confidentiality, integrity, and availability, as the attacker could gain control over the system, access sensitive data, or disrupt system operations. No known exploits are currently reported in the wild, but the vulnerability's nature makes it a critical concern for environments where Intel NUC 9 Extreme Laptop Kits are deployed, especially in scenarios where multiple users share access or where local access controls are weak. The vulnerability was publicly disclosed on August 18, 2022, and affects driver versions before 2.2.0.22, indicating that updating to the latest driver version is essential for mitigation.

For European organizations, the impact of this vulnerability can be substantial, particularly in sectors where Intel NUC 9 Extreme Laptop Kits are used as compact, high-performance computing platforms—such as in engineering, media production, research, and edge computing deployments. An attacker exploiting this vulnerability could escalate privileges from a standard user account to administrative levels, enabling unauthorized access to sensitive corporate data, modification of system configurations, installation of persistent malware, or disruption of critical services. This could lead to data breaches, intellectual property theft, operational downtime, and compliance violations under regulations such as GDPR. The local access requirement limits remote exploitation but does not eliminate risk, especially in environments with shared workstations, insufficient endpoint security, or insider threats. Given the high integrity and availability impact, organizations relying on these devices for critical workloads could face significant operational and reputational damage if exploited.

European organizations should prioritize updating Intel NUC 9 Extreme Laptop Kit drivers to version 2.2.0.22 or later, as this is the definitive fix for the vulnerability. Beyond patching, organizations should enforce strict local access controls and user privilege management to minimize the risk of unauthorized local access. Implementing endpoint detection and response (EDR) solutions can help detect suspicious privilege escalation attempts. Regular auditing of user accounts and permissions on affected devices is recommended to ensure that only necessary privileges are granted. Additionally, organizations should consider network segmentation to isolate devices that use Intel NUC 9 Extreme Laptop Kits, limiting lateral movement in case of compromise. Employing application whitelisting and restricting the execution of unauthorized code can further reduce exploitation risk. Finally, educating users about the risks of local privilege escalation and enforcing strong authentication mechanisms (e.g., multifactor authentication) for local access can help mitigate insider threats.
