Impact

NVIDIA Dynamo for Linux contains a race condition in the LoRA manager singleton initialization. This flaw allows an attacker to trigger concurrent initialization attempts, potentially causing the service to crash or become corrupted. The consequence is loss of availability and the possibility of data tampering, as the Manager may become inconsistently updated or corrupted during the race.

Affected Systems

The vulnerability affects NVIDIA Dynamo running on Linux platforms. No specific version numbers are provided in the CVE data, so any instance of Dynamo that has not been patched or updated after the disclosure is considered at risk.

Risk and Exploitability

The CVSS score of 6.5 places this vulnerability in the medium severity range. The EPSS score is not available, and the issue is not listed in CISA’s KEV catalog, suggesting a lower probability of active exploitation. The attack likely requires local or privileged access to the Dynamo process, as the race condition occurs during internal initialization. Without a remote exploitation vector, the risk is confined to environments where the attacker can influence the execution of Dynamo or its configuration.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Review NVIDIA’s product security portal for a Dynamo release that fixes the race condition and upgrade to that version immediately.
  • If an update is not yet available, disable or remove the LoRA manager functionality to eliminate the vulnerable initialization path until a patch is released.
  • Enable verbose logging for Dynamo and regularly inspect logs for signs of race condition failures or data corruption, and isolate any affected instances.
  • Apply system‑level kernel hardening such as SELinux or AppArmor profiles to limit Dynamo’s permissions and reduce the impact of a potential exploit.
