CVE-2026-47475: CWE-617 Reachable Assertion in NVIDIA TensorRT-LLM
CVE-2026-47475 is a medium severity vulnerability in NVIDIA TensorRT-LLM's OpenAI-compatible inference API. It involves a reachable assertion in the sampler thread that an attacker could trigger. Successful exploitation may cause a denial of service condition. No patch or official remediation guidance is currently provided by the vendor. The affected version is 0.0. No known exploits are reported in the wild.
AI Analysis
Technical Summary
NVIDIA TensorRT-LLM contains a reachable assertion vulnerability (CWE-617) in its OpenAI-compatible inference API. An attacker with local access could trigger this assertion in the sampler thread, potentially causing the application to crash and resulting in denial of service. The CVSS 3.1 base score is 6.2, reflecting medium severity with local attack vector, low complexity, no privileges required, no user interaction, and impact limited to availability. The vulnerability affects version 0.0 of TensorRT-LLM. No vendor advisory or patch information is currently available.
Potential Impact
Exploitation of this vulnerability may lead to denial of service by crashing the sampler thread in the TensorRT-LLM inference API. There is no impact on confidentiality or integrity reported. The attack requires local access and does not require privileges or user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit access to the affected TensorRT-LLM instance to trusted users to reduce risk of local exploitation.
