CVE-2022-21731: Tensorflow is an Open Source Machine Learning Framework. The implementation of shape inference for `ConcatV2` can be use

TensorFlow, an open-source machine learning framework, has a bug in its shape inference (the process of figuring out data dimensions) for the `ConcatV2` operation that can be exploited to crash a program through a segfault (a memory access error). The vulnerability occurs because a type confusion (mixing up different data types) allows a negative value to bypass a safety check, potentially letting attackers cause a denial of service attack (making the system unavailable).
