CVE-2021-37649 Null pointer dereference in `UncompressElement` in TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. The code for tf.rawops.UncompressElement can be made to trigger a null pointer dereference. The implementation obtains a pointer to a CompressedElement from a Variant tensor and then proceeds to dereference it for decompressin...

CVE-2021-37649

CVE-2021-37649 describes a null pointer dereference in tf.raw_ops.UncompressElement within TensorFlow. The issue arises when a Variant tensor does not actually contain a CompressedElement, leading to a nullptr dereference during decompression. A patch has been applied in GitHub commit 7bdf50bb4f5...

CVE-2021-37647 Null pointer dereference in `SparseTensorSliceDataset` in TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. When a user does not supply arguments that determine a valid sparse tensor, tf.rawops.SparseTensorSliceDataset implementation can be made to dereference a null pointer. The implementation has some argument validation but fails...

CVE-2021-37647

CVE-2021-37647 describes a null pointer dereference in TensorFlow’s tf.raw_ops.SparseTensorSliceDataset when creating an empty sparse tensor with mismatched indices/values. The description specifies that validation exists but can dereference a null pointer if indices are empty, leading to a crash...

CVE-2021-37643 Null pointer dereference in `MatrixDiagPartOp` in TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. If a user does not provide a valid padding value to tf.rawops.MatrixDiagPartOp, then the code triggers a null pointer dereference if input is empty or produces invalid behavior, ignoring all values after the first. The...

CVE-2021-37643

CVE-2021-37643 affects TensorFlow’s MatrixDiagPartOp. The issue arises when a user does not supply a valid padding value, causing a NULL pointer dereference (if input is empty) or invalid behavior that ignores subsequent values.
