    Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: JSSE).  Supported versions that are affected are Oracle Java SE: 11.0.31,
    17.0.19, 21.0.11, 25.0.3, 26.0.1; Oracle GraalVM for JDK: 17.0.19 and  21.0.11; Oracle GraalVM Enterprise
    Edition: 21.3.18. Easily exploitable vulnerability allows unauthenticated attacker with network access via
    TLS to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition.  Successful
    attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service
    (partial DOS) of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Note: This
    vulnerability can only be exploited by supplying data to APIs in the specified Component without using
    Untrusted Java Web Start applications or Untrusted Java applets, such as through a web service. CVSS 3.1
    Base Score 5.3 (Availability impacts).  CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).
