CVE-2026-47472 is a vulnerability in NVIDIA TensorRT-LLM involving unsafe deserialization of untrusted data within its inter-process communication layer. An attacker with local access and the same user privileges could exploit this flaw to execute arbitrary code, disclose sensitive information, tamper with data, or cause denial of service. The CVSS 3.1 vector indicates low attack complexity and privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. No vendor advisory or patch information is provided at this time.

The vulnerability allows a local attacker with the same user privileges to potentially execute arbitrary code, access sensitive information, modify data, or disrupt service availability within the affected NVIDIA TensorRT-LLM environment. This could compromise system integrity and confidentiality, leading to significant operational impact.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict local access to trusted users only and monitor for suspicious activity related to inter-process communication in TensorRT-LLM.
