CVE-2022-35981: TensorFlow is an open source platform for machine learning. `FractionalMaxPoolGrad` validates its inputs with `CHECK` fa

TensorFlow, an open source machine learning platform, has a vulnerability in its `FractionalMaxPoolGrad` function (a component that processes pooling operations) where it uses CHECK failures instead of returning errors to validate inputs. If someone sends incorrectly sized inputs to this function, they can trigger a denial of service attack (making the system crash or become unresponsive).
