CVE-2026-47471: NVIDIA TensorRT-LLM Heap Buffer Overflow

NVIDIA TensorRT-LLM

NVIDIA TensorRT-LLM contains a vulnerability in tensor deserialization that enables heap-based buffer overflows. Successful exploitation could lead to information disclosure, data tampering, or denial of service.

disclosed CVENo confirmed exploitation, so this record is tracked as a disclosed vulnerability and not counted as an incident. It moves into the counts if CISA or the vendor confirms exploitation. Why
