ncnn is a high-performance neural network inference framework optimized for the mobile platform. In commit e54f7b1f88434e1d844ea0551b880a1cfb079ce1 and earlier, ncnn allows an out-of-bounds heap write in ncnn::ParamDict::loadparam() when Net::loadparam() loads a malicious .param model file because the parsed parameter id is checked only against id >= NCNNMAXPARAMCOUNT, allowing a negative id to index before the params[NCNNMAXPARAMCOUNT] array. This vulnerability is fixed by commit 5a0288f255daa6c3294f77109f67718e434ec020.
