Root Cause Analysis
The vulnerability stems directly from the unvalidated tensor element access in the Compute
method of RequantizationRangeOp
. The patch adds explicit checks for NumElements()
> 0 before accessing tensor data, confirming the vulnerability was in this function. The code context shows direct memory access operations on potentially empty tensors, matching the CWE-125 description.
