This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

A local user with an ordinary account on the same host can place a file in a shared temporary location that the JDBC driver's native library loading routine will accept and load without verifying its origin. Loading the driver class in a Java application may then run code of that user's choosing inside the application process, which may result in disclosure or alteration of data held by that process or in the process becoming unavailable.
