CVE-2022-41880

Tensorflow vulnerable to Out-of-Bounds Read

Impact

When the BaseCandidateSamplerOp function  receives a value in true_classes larger than range_max, a heap oob vuln occurs.

tf.raw_ops.ThreadUnsafeUnigramCandidateSampler(
    true_classes=[[0x100000,1]],
    num_true = 2,
    num_sampled = 2,
    unique = False,
    range_max = 2,
    seed = 2,
    seed2 = 2)

Patches

We have patched the issue in GitHub commit b389f5c944cadfdfe599b3f1e4026e036f30d2d4.

The 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.
