CVE-2022-35969Public exploitNetwork attack vector

Process crash via unchecked gradient tensor rank

Published Sep 16, 2022 · Updated Apr 23, 2025

Reachable assertion in Google TensorFlow versions before 2.7.2 and versions 2.8.0 and 2.9.0 allows remote attackers to crash a hosting process. Conv2DBackpropInput passes an out_backprop tensor with an unchecked non-four-dimensional rank into shape computation, where a CHECK aborts execution. The affected operation must process a crafted tensor, and failure terminates the containing process rather than only rejecting the operation.
