  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Packaging). Supported versions that are
    affected are 8.0.0-8.0.44, 8.4.0-8.4.7 and 9.0.0-9.5.0. Easily exploitable vulnerability allows unauthenticated attacker
    with network access via MySQL Protocol 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. (CVE-2025-9230)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported versions that are
    affected are 9.0.0-9.5.0. Easily exploitable vulnerability allows low privileged attacker with network access via MySQL
    Protocol 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. (CVE-2026-21949)
