CWE-787: Out-of-bounds Write in MNN model loading (InitNet.cpp).
Bug 1: dims overflow — heap-buffer-overflow WRITE
computeShapeForBlob() loops over Blob.dims from the model file and writes
each element into a fixed dim[MNN_MAX_TENSOR_DIM=9] array. The FlatBuffers
schema allows arbitrary dims vector length, but the C++ struct is fixed:
// InitNet.cpp:24-26… See the full description on the dataset page: https://huggingface.co/datasets/Talson/mnn-dims-oob-poc.
