CVE-2022-21486

Data disclosure and partial service disruption

Published Apr 19, 2022 · Updated Sep 24, 2024

Information disclosure and partial DoS in affected Oracle MySQL Cluster releases allows adjacent attackers to read data and disrupt service. Oracle identifies only the Cluster: General component and has not disclosed the faulty operation or attacker-controlled input. A high-privileged attacker must access the hardware's physical communication segment and obtain another person's interaction; affected branches end at 7.4.35, 7.5.25, 7.6.21, and 8.0.28, and impact is limited to subset disclosure and partial interruption.
