CVE-2022-21727

Advisory

Tensorflow-gpu versions 2.5.3, 2.6.3, 2.7.1 and 2.8.0 include a fix for CVE-2022-21727: The implementation of shape inference for 'Dequantize' is vulnerable to an integer overflow weakness. The 'axis' argument can be '-1' (the default value for the optional argument) or any other positive value at most the number of dimensions of the input. Unfortunately, the upper bound is not checked, and, since the code computes 'axis + 1', an attacker can trigger an integer overflow.
