Summary

Matrix::new() drops uninitialized memory

Details

Matrix::new() internally calls Matrix::fill_with() which uses *ptr = value pattern to initialize the buffer. This pattern assumes that there is an initialized struct at the address and drops it, which results in dropping of uninitialized struct.

Severity

9.8 (Critical)
