CVE-2021-29518: NULL Pointer Dereference
(updated )
TensorFlow is an end-to-end open source platform for machine learning. In eager mode (default in TF), session operations are invalid. However, users could still call the raw ops associated with them and trigger a null pointer dereference. The implementation dereferences the session state pointer without checking if it is valid. Thus, in eager mode, ctx->session_state()
is nullptr and the call of the member function is undefined behavior.
