Technical details
An unsafe deserialization vulnerability (CWE-502) exists in the visual gen server component of NVIDIA TensorRT-LLM. The flaw is rooted in the unauthorized deserialization of ZeroMQ messages. To exploit this, an attacker requires local access to the system with high privileges and must overcome high architectural complexity (AC:H). If successfully exploited, the attacker can achieve arbitrary code execution, leading to a full compromise of confidentiality, integrity, and availability. The vulnerability affects versions up to and including v1.3.0 rc11.
Affected products
- NVIDIA TensorRT-LLM v1.3.0 rc11 and earlier
