Summary

The _distributeToGauges function allocates a fixed-size array matching _gaugeList.length, regardless of how many gauges are actually active. This implementation creates unnecessary memory overhead when working with partially active gauge lists.

Vulnerability Details

The current implementation pre-allocates memory for all possible gauges:

This approach reserves memory space for every gauge in _gaugeList, even though only active gauges require storage. When dealing with lists containing numerous inactive gauges, this creates unnecessary memory bloat.

Impact

• Excessive gas consumption from over-allocation of memory

• Inefficient resource utilization, particularly noticeable in scenarios with a low ratio of active to total gauges

Tools Used

• Manual code review

Recommendations

• Implement dynamic array allocation to store only active gauge weights:

• Consider using a mapping structure to eliminate excess memory allocation

This revised approach using push() ensures memory allocation aligns with the actual number of active gauges, leading to improved gas efficiency and better resource management.
