As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

When performing the inference shape operation of the Transpose operator, if the value in the perm element is greater than or equal to the size of the input_shape, it will access data outside of bounds of input_shape which allocated from heap buffers.

The weakness was disclosed 06/27/2022 as mssa-2021-006. The advisory is available at gitee.com. This vulnerability was named CVE-2021-33649 since 05/28/2021. Technical details are known, but there is no available exploit.
