Technical details

A deserialization vulnerability (CWE-502) exists in NVIDIA TensorRT-LLM (TRT-LLM) across all supported platforms. The flaw stems from the use of an unsafe serialized handle during data processing. An attacker with local access and low privileges can exploit this vulnerability by providing specially crafted serialized data. Successful exploitation can lead to arbitrary code execution, unauthorized data modification, or information disclosure, with the potential to impact components beyond the immediate library (Scope: Changed). Users are advised to refer to NVIDIA advisory 5805 for specific version patching information.
