    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).
    (CVE-2026-46917)

    Vulnerability in Oracle Java SE (component: JSSE).  Supported versions that are affected are Oracle Java
    SE: 8u491, 8u491-perf, 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. Difficult to exploit vulnerability allows
    unauthenticated attacker with network access via TLS to compromise Oracle Java SE.  Successful attacks of
    this vulnerability can result in  unauthorized creation, deletion or modification access to critical data
    or all Oracle Java SE accessible data. 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 5.9 (Integrity impacts).  CVSS Vector:
