Description

This issue is similar to https://issues.apache.org/jira/browse/ARROW-10662.

For the current implementation in the templates, int * int multiplication is used to calculate buffer offset. The result may be larger than Integer.MAX_VALUE, which will lead to integer overflow and unexpected behaviors.
