What is the CVSS score of CVE-2023-31324?

CVE-2023-31324 has a CVSS 3.1 base score of 7.8 (High). CVSS vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H. EPSS exploitation probability: 0.0%.

How to fix or mitigate CVE-2023-31324?

Within 24 hours: Inventory all systems running ROCm and assess exposure in production environments. Within 7 days: Implement network segmentation to isolate ROCm-enabled systems and restrict GPU workload sources to trusted internal networks only. Within 30 days: Establish continuous monitoring for ROCm updates and vendor patch releases; evaluate alternative GPU frameworks if risk tolerance is low and patches remain unavailable.

Executive ViewAI

Why It Matters

CVE-2023-31324 affects ROCm GPU software and allows attackers to manipulate trusted GPU memory interconnect commands, potentially compromising systems using AMD ROCm for compute workloads. Organizations running machine learning, HPC, or data analytics on ROCm-enabled infrastructure should prioritize assessment and mitigation due to the high CVSS score and absence of available patches.

Business Impact: High

Compensating Controls

Implement network segmentation to restrict untrusted code execution on ROCm systems; disable GPU compute features if not essential to business operations; restrict user and application access to ROCm APIs through role-based access controls; monitor GPU command queues for anomalous activity; consider containerization with strict resource policies to limit GPU access scope; maintain air-gapped or restricted network access for systems running ROCm until patches become available.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
