CVE-2026-47473

Local data tampering via arbitrary write

Published Jul 14, 2026 · Updated Jul 14, 2026

Memory corruption in NVIDIA TensorRT-LLM 1.3.0rc16 and earlier allows local users to write data, interrupt service, or read data. NVIDIA identifies a write-what-where condition but has not disclosed the affected component, attacker-controlled value or destination, or operation that performs the write. Exploitation requires local access, no privileges or user interaction, and high-complexity conditions; the bounded impacts are data tampering, service interruption, and information disclosure.
