Technical details

A reachable assertion vulnerability (CWE-617) exists in the OpenAI-compatible inference API of NVIDIA TensorRT-LLM. The flaw is located within the sampler thread and can be triggered by a local attacker. By providing specific input that violates internal logic assumptions, an attacker can cause the program to terminate unexpectedly. This results in a denial of service (DoS) for the affected inference service. The vulnerability affects versions up to and including v1.3.0 rc15.

Affected products
