Name of the Vulnerable Software and Affected Versions TensorFlow versions prior to 2.7.0 TensorFlow versions 2.6.1 and earlier TensorFlow versions 2.5.2 and earlier TensorFlow versions 2.4.4 and earlier

Description TensorFlow is an open source platform for machine learning. The ImmutableConst operation in TensorFlow can be tricked into reading arbitrary memory contents. This is because the tstring TensorFlow string class has a special case for memory mapped strings but the operation itself does not offer any support for this datatype.

Recommendations For versions prior to 2.7.0, update to TensorFlow 2.7.0 or later. For versions 2.6.1 and earlier, update to TensorFlow 2.6.1 or later. For versions 2.5.2 and earlier, update to TensorFlow 2.5.2 or later. For versions 2.4.4 and earlier, update to TensorFlow 2.4.4 or later. As a temporary workaround, consider disabling the ImmutableConst operation until a patch is available.
