An update of the mysql package has been released.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported     versions that are affected are 8.0.0-8.0.45, 8.4.0-8.4.8 and 9.0.0-9.6.0. 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. (CVE-2026-22002)

Note that Nessus relies on the presence of the package as reported by the vendor.

The versions of MySQL Server installed on the remote host are affected by multiple vulnerabilities as referenced in the April 2026 CPU advisory.

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Packaging (OpenSSL)). Supported versions     that are affected are 8.0.0-8.0.45, 8.4.0-8.4.8 and 9.0.0-9.6.0. Easily exploitable vulnerability allows     unauthenticated attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of     this vulnerability can result in takeover of MySQL Server. (CVE-2025-15467)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported versions that are     affected are 8.0.0-8.0.45, 8.4.0-8.4.8 and 9.0.0-9.6.0.

    (CVE-2026-22009)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Packaging (curl)). Supported versions     that are affected are 8.0.0-8.0.45, 8.4.0-8.4.8 and 9.0.0-9.6.0. Difficult to exploit vulnerability allows     unauthenticated attacker with logon to the infrastructure where MySQL Server executes to compromise MySQL Server.
    Successful attacks require human interaction from a person other than the attacker. Successful attacks of this     vulnerability can result in unauthorized creation, deletion or modification access to critical data or all MySQL Server     accessible data as well as unauthorized access to critical data or complete access to all MySQL Server accessible data.
