April 2026 CPU advisory.

  - Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: JAXP). Supported versions that are affected are Oracle Java SE: 8u481,
    8u481-b50, 8u481-perf, 11.0.30, 17.0.18, 21.0.10, 25.0.2, 26; Oracle GraalVM for JDK: 17.0.18 and 21.0.10;
    Oracle GraalVM Enterprise Edition: 21.3.17. 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
    access to critical data or complete access to all Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM
    Enterprise Edition accessible data. Note: This vulnerability can be exploited by using APIs in the
    specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also
    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. (CVE-2026-22016)

    Oracle Java SE (component: Networking). Supported versions that are affected are Oracle Java SE: 8u481-perf,
    11.0.30, 17.0.18, 21.0.10, 25.0.2, 26; Oracle GraalVM for JDK: 17.0.18 and 21.0.10; Oracle GraalVM Enterprise
    Edition: 21.3.17. 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 can be exploited by using APIs in the specified Component, e.g., through a web
    service which supplies data to the APIs. This vulnerability also 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. (CVE-2026-34282)

  - The issue was addressed with improved memory handling. This issue is fixed in Safari 26.3, iOS 18.7.5 and
    iPadOS 18.7.5, iOS 26.3 and iPadOS 26.3, macOS Tahoe 26.3, visionOS 26.3. A remote attacker may be able to
    cause a denial-of-service. (CVE-2026-20652)

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