"The version of IBM WebSphere eXtreme Scale installed on the remote host is prior to 8.6.1.6. It is, therefore, affected
by multiple vulnerabilities as referenced in the 7267689 advisory.

  - In the Eclipse OMR port library component since release 0.2.0, an API function to return the textual names
    of all supported processor features was not accounting for the separator inserted between processor
    features. If the output buffer supplied to this function was incorrectly sized, failing to account for the
    separator when determining when a write to the buffer was safe could lead to a buffer overflow. This issue
    is fixed in Eclipse OMR version 0.8.0. (CVE-2026-1188)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: Security). Supported versions that are affected are Oracle Java SE: 8u471,
    8u471-b50, 8u471-perf, 11.0.29, 17.0.17, 21.0.9, 25.0.1; Oracle GraalVM for JDK: 17.0.17 and 21.0.9;
    Oracle GraalVM Enterprise Edition: 21.3.16. Easily exploitable vulnerability allows unauthenticated
    attacker with network access via multiple protocols 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 hang or frequently repeatable crash (complete DOS) of Oracle Java SE, Oracle GraalVM
    for JDK, Oracle GraalVM Enterprise Edition. Note: This vulnerability applies to Java deployments,
    typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load
    and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for
    security. This vulnerability does not apply to Java deployments, typically in servers, that load and run
    only trusted code (e.g., code installed by an administrator). (CVE-2026-21945)

  - A Blind Server-Side Request Forgery (SSRF) vulnerability exists in Oracle Java 21. The vulnerability,
    which leads to Denial of Service (DoS), is present in the x509 certificate path validation mechanism when
    the non-default system property com.sun.security.enableAIAcaIssuers is set to true. (CVE-2026-21945)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
