Name of the Vulnerable Software and Affected Versions MySQL Server versions 8.4.3 and prior MySQL Server versions 9.1.0 and prior

Description The issue is related to the MySQL Server product, specifically the Server: Security: Privileges component.

Successful attacks can result in the unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. The vulnerability is difficult to exploit and can be triggered remotely through the MySQL network protocol.

For MySQL Server versions 9.1.0 and prior, update to a version later than 9.1.0 to resolve the issue. As a temporary workaround, consider restricting network access to MySQL Server to minimize the risk of exploitation.
