Miggo AIRoot Cause Analysis
The vulnerability stems directly from unvalidated divisions by stride_h and stride_w in the TransposeConv operator's optimized implementation. The code snippet shows raw division operations ((height + pad_t + pad_b - filter_h)/stride_h) without prior validation of stride values. The subsequent patch added validation checks in transpose_conv.cc, confirming the vulnerability existed in the calculation logic within optimized_ops.h. Though the exact function name isn't explicitly stated, the line numbers and context indicate this is part of the TransposeConv operator's implementation.
