Summary

TensorFlow, an open source machine learning platform, has a flaw in `QuantizedBiasAdd`. When the `min_input`, `max_input`, `min_bias` and `max_bias` tensors have a nonzero rank, the operation segfaults, which an attacker can use to trigger a denial of service. The issue is tracked as CVE-2022-35972.

Mitigation

Patched in GitHub commit 785d67a78a1d533759fcd2f5e8d6ef778de849e0. The fix will be included in TensorFlow 2.10.0 and cherrypicked to TensorFlow 2.9.1, 2.8.1 and 2.7.2. There are no known workarounds.
