Summary
TensorFlow, an open source machine learning platform, has a vulnerability in its `tf.function` API (a feature that converts Python functions into optimized operations) where mutually recursive functions (functions that call each other back and forth) can cause a deadlock using a non-reentrant Lock (a mechanism that prevents simultaneous access but doesn't allow the same thread to re-enter it). An attacker could cause a denial of service by tricking users into loading vulnerable models, though this scenario is uncommon.
Solution / Mitigation
The fix will be included in TensorFlow 2.7.0. The fix will also be backported (applied to older supported versions) to TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4.
