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. The root cause is in MatrixDiagV2/V3 path handling inputs, and patches fix the issue (commit a7116dd39…) with the fix slated for TensorFlow 2...

CVE-2021-29516

TensorFlow CVE-2021-29516 describes a null pointer dereference in tf.raw_ops.RaggedTensorToVariant when provided with an invalid ragged tensor. The issue arises because batched_ragged.splits(0) is dereferenced without validating non-emptiness. Affected: TensorFlow and related entries indicate the...

CVE-2021-29516 Null pointer dereference via invalid Ragged Tensors

TensorFlow is an end-to-end open source platform for machine learning. Calling tf.rawops.RaggedTensorToVariant with arguments specifying an invalid ragged tensor results in a null pointer dereference. The implementation of RaggedTensorToVariant...

CVE-2021-29517

CVE-2021-29517 affects TensorFlow Conv3D: division-by-zero in the Conv3D kernel caused by a modulo on user input (fifth filter dimension), potentially triggering an Eigen assertion and a crash. The issue is addressed by a TensorFlow fix in 2.5.0, with cherry-picks to 2.4.2, 2.3.3, 2.2.3 and 2.1.4...

CVE-2021-29518

CVE-2021-29518 describes a vulnerability in TensorFlow where, in eager mode, session operations can dereference a null session_state pointer, leading to undefined behavior. Concrete details from connected documents show the root cause in tensor flow core/kernels/session_ops.cc, where ctx->sess...

CVE-2021-29518 Session operations in eager mode lead to null pointer dereferences

TensorFlow is an end-to-end open source platform for machine learning. In eager mode default in TF 2.0 and later, session operations are invalid. However, users could still call the raw ops associated with them and trigger a null pointer dereference. The...

CVE-2021-29519

TensorFlow vulnerability CVE-2021-29519 arises from a type-confusion in tf.raw_ops.SparseCross where a tstring input is treated as int64, enabling a CHECK-fail and potential DoS. The issue is rooted in SparseCross_op.cc logic that mishandles dtype, returning a fingerprint from a string when value...

CVE-2021-29519 CHECK-fail in SparseCross due to type confusion

TensorFlow is an end-to-end open source platform for machine learning. The API of tf.rawops.SparseCross allows combinations which would result in a CHECK-failure and denial of service. This is because the...

CVE-2021-29520

TensorFlow CVE-2021-29520 concerns a heap buffer overflow in Conv3DBackprop* due to missing validation that assumes input, filter_sizes, and out_backprop have identical shapes. Multiple sources (OSV entries and GHSA advisory) corroborate the issue and patch lineage. The vulnerability affects Conv...

CVE-2021-29520 Heap buffer overflow in `Conv3DBackprop*`

TensorFlow is an end-to-end open source platform for machine learning. Missing validation between arguments to tf.rawops.Conv3DBackprop operations can result in heap buffer overflows. This is because the...

CVE-2021-29521

TensorFlow is an end-to-end open source platform for machine learning. Specifying a negative dense shape in tf.rawops.SparseCountSparseOutput results in a segmentation fault being thrown out from the standard library as std::vector invariants are broken. This is because the...

CVE-2021-29521

TensorFlow CVE-2021-29521: A bug in tf.raw_ops.SparseCountSparseOutput triggers a segmentation fault when dense_shape contains negative values. Root cause is the implementation assuming the first element of dense_shape is positive to initialize BatchedMap; with multi-element shapes, num_batches d...
