CVE-2025-0034 is a medium-severity vulnerability identified in the AMD Instinct™ MI300X accelerator, specifically within the Trusted Execution Environment (TEE) System on Chip (SOC) driver. The vulnerability arises due to insufficient parameter sanitization when processing the DRV_SOC_CMD_ID_SRIOV_SPATIAL_PART command. This flaw allows an attacker with high privileges and local access to issue a malformed command that triggers an out-of-bounds write or read operation beyond the allocated array boundaries. Such memory corruption can lead to a loss of platform integrity or cause a denial of service (DoS) by crashing or destabilizing the affected system. The vulnerability is classified under CWE-787 (Out-of-bounds Write), indicating a memory safety issue. Exploitation requires local access with high privileges and no user interaction, and the attack complexity is high, as reflected in the CVSS vector (AV:L/AC:H/PR:H/UI:N). No known exploits are currently reported in the wild, and no patches have been linked yet. The affected product, AMD Instinct™ MI300X, is a high-performance GPU accelerator used primarily in data centers and high-performance computing environments, often deployed in servers handling critical workloads.

For European organizations, especially those operating data centers, research institutions, and enterprises relying on AMD Instinct MI300X accelerators for AI, machine learning, or HPC workloads, this vulnerability poses a risk to system stability and platform integrity. An attacker exploiting this flaw could cause denial of service conditions, potentially disrupting critical computational tasks and services. While the vulnerability does not directly compromise confidentiality, the integrity of computations and availability of services could be impacted, leading to operational downtime and potential loss of trust in computational results. Given the high privilege and local access requirements, the threat is more relevant in environments where multiple users or tenants share hardware resources, such as cloud providers or multi-tenant HPC clusters. The lack of known exploits reduces immediate risk, but the potential for future exploitation necessitates proactive mitigation.

European organizations should implement strict access controls to limit local high-privilege access to systems running AMD Instinct MI300X accelerators. Employing robust user and process isolation mechanisms can reduce the risk of unauthorized command issuance. Monitoring and auditing of driver-level commands and system logs may help detect anomalous activities related to DRV_SOC_CMD_ID_SRIOV_SPATIAL_PART usage. Organizations should engage with AMD for timely updates and patches once available and plan for prompt deployment. Additionally, adopting hardware and software integrity verification tools can help detect memory corruption or instability early. For multi-tenant environments, consider isolating workloads to minimize the risk of privilege escalation or lateral movement. Finally, maintaining up-to-date system firmware and drivers reduces exposure to known vulnerabilities.
