CVE-2022-21325

Information disclosure via array out-of-bounds read

Published Jan 19, 2022 · Updated Sep 24, 2024

Improper array-index validation in affected Oracle MySQL Cluster releases allows adjacent high-privilege attackers to read data and disrupt service. A Data Node job handler uses user-supplied data as an array index without proper validation, allowing a read past the array's end. Oracle states that exploitation requires access to the physical communication segment, high privileges, high complexity, and another person's interaction; impact is limited to partial data disclosure and partial service interruption.
