Hello,

I noticed there was a new pull request https://github.com/deepseek-ai/DeepEP/pull/454， but could not find the issue related. So what's the orignal issue?

Thanks

The pr fixed a potential integer overflow in the buffer address offset calculation. If your buffer size exceeds the range of a 32‑bit integer, you may encounter this issue.
