Please Note: Java CVEs do not always include OpenJDK versions, but are confirmed separately by Tenable using the patch
versions from the referenced OpenJDK security 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)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    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)

  - 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: 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 HTTPS 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 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-2026-22021)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of
    Oracle Java SE (component: JGSS). 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. Difficult to exploit 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 require human interaction from a person other than
    the attacker. 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 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-2026-22013)

  - An integer overflow in the tt_var_load_item_variation_store function of the Freetype library in versions
    2.13.2 and 2.13.3 may allow for an out of bounds read operation when parsing HVAR/VVAR/MVAR tables in
    OpenType variable fonts. This issue is fixed in version 2.14.2. (CVE-2026-23865)
