Summary
CVE-2021-41204 affects TensorFlow versions where the Grappler optimizer's constant folding phase may deep copy a resource tensor. This causes a segfault, since those tensors are meant to remain unchanged.
Mitigation
The fix will be included in TensorFlow 2.7.0. The commit will also be cherry-picked to TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4.
