CVE-2024-21213

Privileged service interruption via undisclosed InnoDB flaw

Published Oct 15, 2024 · Updated Nov 3, 2025

Denial of service in Oracle MySQL Server 8.0.39, 8.4.2, and 9.0.1 and earlier allows local users to hang or repeatedly crash the server. Oracle identifies InnoDB as the component but has not published the vulnerable locus or the operation that mishandles input. Exploitation requires high privileges on the host and interaction by another person; the documented consequence is service interruption only.
