{"id":"PYSEC-2026-3376","summary":"Out of bounds segmentation fault due to unequal op inputs in Tensorflow","details":"### Impact\n [`tf.raw_ops.DynamicStitch`](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/kernels/dynamic_stitch_op.cc) specifies input sizes when it is [registered](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/ops/data_flow_ops.cc). \n```cpp\nREGISTER_OP(\"DynamicStitch\")\n    .Input(\"indices: N * int32\")\n    .Input(\"data: N * T\")\n    .Output(\"merged: T\")\n    .Attr(\"N : int \u003e= 1\")\n    .Attr(\"T : type\")\n    .SetShapeFn(DynamicStitchShapeFunction);\n```\nWhen it receives a differing number of inputs, such as when it is called with an `indices` size 1 and a `data` size 2, it will crash.\n```python\nimport tensorflow as tf\n\n# indices = 1*[tf.random.uniform([1,2], dtype=tf.dtypes.int32, maxval=100)]\nindices = [tf.constant([[0, 1]]),]\n\n# data = 2*[tf.random.uniform([1,2], dtype=tf.dtypes.float32, maxval=100)]\ndata = [tf.constant([[5, 6]]), tf.constant([[7, 8]])]\n\ntf.raw_ops.DynamicStitch(\n    indices=indices, \n    data=data)\n```\n\n### Patches\nWe have patched the issue in GitHub commit [f5381e0e10b5a61344109c1b7c174c68110f7629](https://github.com/tensorflow/tensorflow/commit/f5381e0e10b5a61344109c1b7c174c68110f7629).\n\nThe fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1 as this is also affected.\n\n\n### For more information\nPlease consult [our security guide](https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md) for more information regarding the security model and how to contact us with issues and questions.\n\n\n### Attribution\nThis vulnerability has been reported by Zizhuang Deng of IIE, UCAS\n","aliases":["BIT-tensorflow-2022-41883","CVE-2022-41883","GHSA-w58w-79xv-6vcj","PYSEC-2026-1042","PYSEC-2026-3251"],"modified":"2026-07-13T16:42:49.026599256Z","published":"2026-07-13T14:19:51.457784Z","references":[{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-w58w-79xv-6vcj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-41883"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/commit/f5381e0e10b5a61344109c1b7c174c68110f7629"},{"type":"PACKAGE","url":"https://github.com/tensorflow/tensorflow"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/kernels/dynamic_stitch_op.cc"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/ops/data_flow_ops.cc"},{"type":"PACKAGE","url":"https://pypi.org/project/tensorflow-cpu"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-w58w-79xv-6vcj"}],"affected":[{"package":{"name":"tensorflow-cpu","ecosystem":"PyPI","purl":"pkg:pypi/tensorflow-cpu"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.10.0"},{"fixed":"2.10.1"}]}],"versions":["2.10.0"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/tensorflow-cpu/PYSEC-2026-3376.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:H"}]}
