"According to its self-reported version number, IBM Db2 is affected by multiple denial of service vulnerabilities:

  - IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) could allow an authenticated user to
    cause a denial of service due to improper neutralization of special elements in data query logic when
    certain configurations exist. (CVE-2025-14688)

  - IBM Db2 for Linux, UNIX and Windows (includes DB2 Connect Server) could allow an authenticated user to
    cause a denial of service using a specially crafted SQL query due to improper allocation of system
    resources. (CVE-2025-36122)

  - IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) could allow an authenticated user to
    cause a denial of service due to improper neutralization of special elements in data query logic.
