TensorFlow vulnerable to `CHECK` failure in `SobolSample` via missing validation
Medium5.9CVE-2022-35935 · Published Sep 16, 2022 · updated Jul 13, 2026
### Impact The implementation of SobolSampleOp is vulnerable to a denial of service via CHECK-failure (assertion failure) caused by assuming `input(0)`, `input(1)`, and `input(2)` to be scalar. ```python import tensorflow as tf tf.raw_ops.SobolSample(dim=tf.constant([1,0]), num_results=tf.constant([1]), skip=tf.constant([1])) ``` ### Patches We have patched the issue in GitHub commit [c65c67f88ad770662e8f191269a907bf2b94b1bf](https://github.com/tensorflow/tensorflow/commit/c65c67f88ad770662e8f191269a907bf2b94b1bf). The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range. ### For more information Please 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. ### Attribution This vulnerability has been reported by: - Kang Hong Jin from Singapore Management University - Neophytos Christou, Secure Systems Labs, Brown University - 刘力源, Information System & Security and Countermeasures Experiments Center, B...
