Name of the Vulnerable Software and Affected Versions TensorFlow versions prior to 2.6.0 TensorFlow versions 2.5.1 and earlier TensorFlow versions 2.4.3 and earlier TensorFlow versions 2.3.4 and earlier

Description An attacker can craft a TFLite model that would trigger a null pointer dereference, resulting in a crash and denial of service. The implementation unconditionally dereferences a pointer.

Recommendations For versions prior to 2.6.0, update to TensorFlow 2.6.0 or later. For versions 2.5.1 and earlier, update to TensorFlow 2.5.1 or later. For versions 2.4.3 and earlier, update to TensorFlow 2.4.3 or later. For versions 2.3.4 and earlier, update to TensorFlow 2.3.4 or later.
