Summary

Oracle MySQL Server versions 8.4.0-8.4.12, 9.7.0-9.7.3 and 26.7.0-26.7.1, and MySQL Cluster versions 8.0.0-8.0.49, 8.4.0-8.4.12, 9.7.0-9.7.3 and 26.7.0-26.7.1, contain an uncontrolled resource consumption flaw (CWE-400) in the InnoDB component. A highly privileged local attacker with logon to the host can exploit it, and it requires interaction from a person other than the attacker, to cause a hang or repeatable crash of the server.
