CVE-2026-14647

ONNX Runtime (onnxruntime) up to 1.21.x is affected by CVE-2026-14647 due to a weakness in convPoolShapeInference_opset19 in ONNX’s old.cc (onnx/defs/nn). The root cause is an out-of-bounds read introduced in this path, enabling remote exploitation. Public exploits exist per the description. Reme...

CVE-2026-14647 onnx onnxruntime old.cc convPoolShapeInference_opset19 out-of-bounds

A weakness has been identified in onnx up to 1.21.x. This vulnerability affects the function convPoolShapeInferenceopset19 of the file onnx/defs/nn/old.cc of the component onnxruntime. This manipulation causes out-of-bounds read. It is possible to initiate the attack remotely. The exploit has bee...

CVE-2021-41216
