When a user does not supply arguments that…","summary":"TensorFlow's `tf.raw_ops.SparseTensorSliceDataset` implementation can dereference a null pointer when a user does not supply arguments that determine a valid sparse tensor. The argument validation does not handle the case where either `indices` or `values` is provided for an empty sparse tensor while the other is not, so an empty `indices` input causes a null pointer dereference during the monotonic-increase check.","solution":"Fixed in GitHub commit 02cc160e29d20631de3859c6653184e3f876b9d7.
