# MySQL Server: high-privilege user can crash the server over network

A flaw in the MySQL Server Components Services component lets a highly privileged user cause a hang or repeatable crash of MySQL Server and MySQL Cluster. The sources describe only a denial of service, with no data exposure or code execution.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Run `SELECT VERSION();` in the MySQL client and compare against the affected ranges 9.7.0-9.7.3 and 26.7.0-26.7.1
- Check whether MySQL Cluster is in use on the affected versions

## Fix

- Upgrade MySQL Server to a release after 9.7.3 or 26.7.1 as published by Oracle (exact fixed version: unknown)
- Upgrade MySQL Cluster to the same fixed release line (exact fixed version: unknown)
