CVE-2024-31073 is a medium-severity vulnerability affecting Intel(R) oneAPI Level Zero software, which is a low-level programming interface designed to provide direct access to GPU and accelerator hardware. The vulnerability arises from an uncontrolled search path issue, where the software improperly handles the locations from which it loads certain components or libraries. This flaw can be exploited by an authenticated user with local access to the system to escalate their privileges. Specifically, the attacker could manipulate the search path to load malicious code or libraries, thereby gaining higher privileges than originally granted. The vulnerability requires local access and user interaction, and the attacker must already have low-level privileges (PR:L) but can potentially elevate these privileges to a higher level. The CVSS 4.0 score of 5.4 reflects a medium severity, considering the complexity of attack (AC:H), the need for authentication (AT:P), and user interaction (UI:A). The vulnerability impacts confidentiality, integrity, and availability at a high level (VC:H, VI:H, VA:H), indicating that successful exploitation could lead to significant compromise of system security. There are no known exploits in the wild at this time, and no patches or mitigations have been explicitly linked in the provided data. Intel oneAPI Level Zero is primarily used in environments requiring high-performance computing and GPU acceleration, including research institutions, data centers, and enterprises leveraging AI and machine learning workloads.

For European organizations, this vulnerability poses a risk primarily to entities utilizing Intel oneAPI Level Zero software for GPU-accelerated computing tasks. This includes sectors such as scientific research, financial services employing high-frequency trading algorithms, automotive industries engaged in AI development, and cloud service providers hosting GPU workloads. Exploitation could allow malicious insiders or compromised low-privilege users to escalate privileges, potentially leading to unauthorized access to sensitive data, disruption of critical computational tasks, or deployment of persistent malicious code within high-performance computing environments. Given the high impact on confidentiality, integrity, and availability, organizations could face data breaches, intellectual property theft, or operational downtime. The requirement for local access and authentication limits remote exploitation risks but does not eliminate insider threats or risks from compromised accounts. The absence of known exploits reduces immediate risk but does not preclude targeted attacks, especially in high-value environments.

European organizations should implement the following specific mitigations: 1) Restrict local access to systems running Intel oneAPI Level Zero software to trusted personnel only, employing strict access controls and monitoring. 2) Employ application whitelisting and integrity verification mechanisms to detect unauthorized modifications or loading of untrusted libraries. 3) Monitor system logs and use behavioral analytics to detect unusual privilege escalation attempts or anomalous library loading activities. 4) Maintain up-to-date inventories of software versions and promptly apply patches or updates from Intel once available. 5) Use containerization or sandboxing techniques to isolate GPU workloads and limit the impact of potential privilege escalations. 6) Conduct regular security training to raise awareness about the risks of local privilege escalation and the importance of safeguarding credentials and access. 7) Implement multi-factor authentication for local logins where feasible to reduce the risk of credential compromise. These measures go beyond generic advice by focusing on controlling local access, monitoring for specific exploitation behaviors, and isolating vulnerable components.
