## Technical details

A vulnerability classified as Missing Authentication for Critical Function (CWE-306) exists in NVIDIA TensorRT-LLM for Linux. The flaw allows a local attacker with high privileges to bypass authentication requirements for sensitive functions. Due to the high complexity of the attack and the requirement for elevated local permissions, the CVSS score is 6.4. Successful exploitation could enable arbitrary code execution, unauthorized data modification, and information disclosure within the affected environment. The vulnerability impacts versions up to and including v1.3.0 rc12.
