I too agree with the above answer, there is always a chance to miss the issues, it may be major or minor. The reason may be the impact of new changes, etc.

So the solution may be we've to escalate the issue first to our lead then we can decided what to do, i can escalate in a smarter way like " Found below issue while doing regression testing as it may be due to new changes ..." as my project is always having change requests.
