[Context:] Patch commits are useful to complete vulnerability datasets for training ML models and for developers to find a safe version for their dependencies. [Objective:] However, there is a gap in the state-of-the-art (SOTA) for a lightweight low False Positive patch commit finder. [Method:] We implemented Hash4Patch, a new tool to be used along with a current SOTA patch finder. We then validated it with a dataset of 160 CVEs. [Results:] Our approach significantly reduced the False Positives produced by a state-of-the-art tool with only 1 minute of additional running time on average. [Conclusions:] Our tool is able to effectively and efficiently reduce the number of alerts found by other patch commit finders, thus minimizing the manual effort needed by developers.
