MNN-Code-Doc-ZH
MNN-Code-Doc-ZH: MNN源码结构化中文文档数据集
数据集简介
本数据集是针对深度学习推理框架 MNN(https://github.com/alibaba/MNN/tree/3.2.2) 版本的源代码，通过 AI 协同的方式，生成的结构化中文文档。数据集旨在为 MNN 的学习者、开发者和研究人员提供一份可被机器理解的高质量语料，以促进代码理解、代码生成、智能问答等领域的大模型研究。
数据集包含两种格式，以适应不同的训练任务：
继续预训练 (Pre-train) 数据集: mnn-code-doc-pretrain-322.jsonl
指令微调 (SFT) 数据集: mnn-code-doc-sft-322.jsonl
数据格式
1. 预训练 (Pre-train) 数据
文件 mnn-code-doc-pretrain-322.jsonl 用于领域知识注入，每一行是一个 JSON 对象，包含一个字段：

MNN computeShapeForBlob dims overflow + outputIndexes OOB
Vulnerability
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:
