Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Options). Supported versions that are affected are 5.7.38 and prior and 8.0.29 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. CVSS 3.1 Base Score 4.9 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H).

Security readout for executives and security teams

Plain-English summary

This is a MySQL Server denial-of-service issue. An attacker who already has high privileges and network access can make affected MySQL servers hang or crash repeatedly. It does not indicate data theft or tampering, but an outage can disrupt applications that depend on the database.

Executive priority

Treat as a reliability risk for business-critical databases. Prioritize systems supporting customer-facing or operational applications, especially where many privileged accounts or exposed database networks exist.

Technical view

CVE-2022-21515 affects Oracle MySQL Server component Server: Options in versions 5.7.38 and prior, and 8.0.29 and prior. The CVSS vector is network-accessible, low complexity, high privileges required, no user interaction, with high availability impact only.

Likely exposure

Exposure is most relevant where affected MySQL versions are reachable over a network by privileged database users, administrators, service accounts, or compromised high-privilege credentials.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation. Exploitation requires high privileges, limiting broad external risk, but successful abuse can cause a complete MySQL denial of service.

Researcher notes

No CWE is supplied in the bundle. The issue is availability-only with PR:H and AV:N. Evidence supports affected versions and DoS impact, but the bundle does not provide exploit details or a specific root cause.

Mitigation direction

  • Identify MySQL Server instances at 5.7.38 or prior, and 8.0.29 or prior.
  • Apply updates or packages referenced by Oracle, Fedora, or applicable vendor advisories.
  • Restrict network access to MySQL management and database interfaces.
  • Review high-privilege MySQL accounts and remove unnecessary access.
  • Monitor MySQL availability and repeated crash or hang events.

Validation and detection

  • Inventory MySQL Server versions across production, staging, and managed appliances.
  • Confirm whether any affected instance is network reachable by high-privilege users.
  • Check vendor advisory status for Oracle, Fedora, NetApp, or appliance dependencies.
  • Verify updated systems no longer report affected MySQL versions.
  • Review logs for unexplained MySQL hangs or repeated crash patterns.
