CVE-2026-11329: A vulnerability has been found in onnx onnx-mlir up to 0.5.0.0. Affected by this issue is the function generate_hash_key

A vulnerability exists in ONNX MLIR (a tool that converts machine learning models to code) versions up to 0.5.0.0 where the generate_hash_key function uses a weak hash (a simple algorithm for converting data into a fixed-length code that is easy to reverse or predict). The vulnerability requires local access to exploit and is difficult to execute in practice.
