{"id":"GHSA-8w5g-3wcv-9g2j","summary":"Tensorflow vulnerable to Out-of-Bounds Read","details":"### Impact\nWhen the [`BaseCandidateSamplerOp`](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/kernels/candidate_sampler_ops.cc) function  receives a value in `true_classes` larger than `range_max`, a heap oob vuln occurs.\n```python\ntf.raw_ops.ThreadUnsafeUnigramCandidateSampler(\n    true_classes=[[0x100000,1]],\n    num_true = 2,\n    num_sampled = 2,\n    unique = False,\n    range_max = 2,\n    seed = 2,\n    seed2 = 2)\n```\n\n### Patches\nWe have patched the issue in GitHub commit [b389f5c944cadfdfe599b3f1e4026e036f30d2d4](https://github.com/tensorflow/tensorflow/commit/b389f5c944cadfdfe599b3f1e4026e036f30d2d4).\n\nThe fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these are also affected and still in supported range.\n\n\n### For more information\nPlease consult [our
