we can just add //nolint:gosec // G115 we validate that there is no overflow here or something similar. since we already validate it in this block, but the linter isn't smart enough to detect that.

@lanc07 thank you so much allan, let me know you want me to help / continue this. we mostly need to check if we validate boundaries and don't have any overflows and add nolint.

Thank you Allan, sorry i didn't see that you fixed the issues.
