Can you explain this vulnerability to me?
This vulnerability exists in the MySQL Server product of Oracle MySQL, specifically in the InnoDB component. It affects supported versions 8.0.0-8.0.45, 8.4.0-8.4.8, and 9.0.0-9.6.0. The flaw allows a highly privileged attacker with network access through multiple protocols to exploit the server.
Exploitation of this vulnerability can lead to unauthorized ability to cause the MySQL Server to hang or crash repeatedly, resulting in a complete denial of service (DoS).
How can this vulnerability impact me? :
The main impact of this vulnerability is on the availability of the MySQL Server. An attacker with high privileges and network access can cause the server to hang or crash repeatedly, leading to a denial of service.
This means that legitimate users may be unable to access the database services, potentially disrupting business operations that rely on MySQL Server.
