CVE-2021-29513

TensorFlow vulnerability CVE-2021-29513 arises when calling TF operations with tensors of non-numeric types, causing a null pointer dereference due to a type confusion in the Python-to-C++ array conversion (ndarray_tensor.cc). Root cause: PyArray_DESCR_to_TF_DataType path can dereference NULL in ...

CVE-2021-29514

TensorFlow RaggedBincount vulnerability (CVE-2021-29514) in the RaggedBincount kernel can cause a heap out-of-bounds write when the splits argument references an invalid SparseTensor, leading to a write at out(-1, bin). The issue is triggered by setting splits(0) to 7, causing batch_idx to remain...

CVE-2021-29515

The CVE-2021-29515 issue affects TensorFlow MatrixDiag* ops: input tensors are not validated to be non-empty, which can lead to a null pointer dereference.
