CVE-2026-47470

Local service interruption via invalid chat input

Published Jul 14, 2026 · Updated Jul 14, 2026

Improper input validation in NVIDIA TensorRT-LLM 1.3.0rc14 and earlier allows local users to interrupt the gRPC server via the chat API. NVIDIA identifies the gRPC chat endpoint as the affected locus but has not published which request field bypasses validation or whether the resulting failure is a crash or hang. No privileges or user interaction are required, but the attacker must have local access; the published impact is limited to service availability.
