{"schema_version":"1.7.5","id":"GHSA-27j5-4p9v-pp67","published":"2021-08-25T14:43:40Z","modified":"2026-07-08T06:27:27.688704624Z","aliases":["BIT-tensorflow-2021-37644","CVE-2021-37644","PYSEC-2021-266","PYSEC-2021-557","PYSEC-2021-755"],"summary":"`std::abort` raised from `TensorListReserve`","details":"### Impact\nProviding a negative element to `num_elements` list argument of  `tf.raw_ops.TensorListReserve` causes the runtime to abort the process due to reallocating a `std::vector` to have a negative number of elements:\n\n```python\nimport tensorflow as tf\n\ntf.raw_ops.TensorListReserve(\n  element_shape = tf.constant([1]),\n  num_elements=tf.constant([-1]),\n  element_dtype = tf.int32)\n```\n\nThe [implementation](https://github.com/tensorflow/tensorflow/blob/8d72537c6abf5a44103b57b9c2e22c14f5f49698/tensorflow/core/kernels/list_kernels.cc#L312) calls `std::vector.resize()` with the new size controlled by input given by the user, without checking that this input is valid.\n\n### Patches\nWe have patched the issue in GitHub commit [8a6e874437670045e6c7dc6154c7412b4a2135e2](https://github.com/tensorflow/tensorflow/commit/8a6e874437670045e6c7dc6154c7412b4a2135e2).\n\nThe fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.\n\n### For more information \nPlease consult
