AGMP Partners Initial Discovery and Context Alright team, let’s dig into something that just dropped on the vulnerability front: CVE-2026-44512. It’s a null pointer dereference impacting Open Neural Network Exchange (ONNX), specifically within the onnx.version_converter.convert_version() function. This bug affects ONNX versions from 1.9.0 up to, but not including, 1.22.0. Given today’s date, July 12, 2026, it’s a critical reminder that vulnerabilities aren't just for traditional software stacks; machine learning frameworks are increasingly becoming prime targets for adversaries. The fact that this is a null pointer dereference, while often associated with denial-of-service (DoS), in the right context with careful exploit development, can absolutely open doors to more severe outcomes. Remember, ONNX is becoming a de-facto standard for ML model interoperability across various runtimes and
