AI Analysis
Technical Summary
CVE-2026-47475 is a reachable assertion vulnerability (CWE-617) in NVIDIA TensorRT-LLM's OpenAI-compatible inference API. An attacker can cause the sampler thread to hit an assertion failure, leading to denial of service conditions. The CVSS 3.1 base score is 6.2 (medium severity) with local attack vector, low attack complexity, no privileges required, no user interaction, and impact limited to availability. The affected version explicitly identified is 0.0. No vendor advisory or patch information is currently available.
Potential Impact
Successful exploitation results in denial of service by triggering an assertion failure in the sampler thread. There is no impact on confidentiality or integrity. The service may become unavailable or crash, affecting system availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider restricting local access to the vulnerable component to trusted users only, as the attack vector is local. Monitor for vendor updates regarding patches or official mitigations.
