The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Vulnerability in the Oracle JavaFX product of Oracle Java SE (component: JavaFX). Supported versions that     are affected are Oracle JavaFX: 25.0.4 and 27. Difficult to exploit vulnerability allows unauthenticated     attacker with network access via multiple protocols to compromise Oracle JavaFX. Successful attacks     require human interaction from a person other than the attacker. Successful attacks of this vulnerability     can result in unauthorized read access to a subset of Oracle JavaFX 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-2026-91477)

Note that Nessus relies on the presence of the package as reported by the vendor.

The 8u503, 8u503-perf, 11.0.32.1, 17.0.20.1, 21.0.12.1, 25.0.4.1, 26.0.2 and 27 releases of Oracle Java SE installed on the remote host are affected by multiple vulnerabilities as referenced in the October 2026 CPU advisory.

  - Vulnerability in the Oracle Java SE, Oracle JavaFX product of Oracle Java SE (component: JavaFX     (WebKitGTK)). Supported versions that are affected are Oracle Java SE: 8u503; Oracle JavaFX: 21.0.12, 25.0.4     and 27. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple     protocols to compromise Oracle Java SE, Oracle JavaFX. Successful attacks require human interaction from a     person other than the attacker. Successful attacks of this vulnerability can result in takeover of Oracle     Java SE, Oracle JavaFX. (CVE-2026-43660)

  - Vulnerability in Oracle Java SE (component: Java plugin). Supported versions that are affected are Oracle     Java SE: 8u503 and 8u503-perf. Difficult to exploit vulnerability allows low privileged attacker with logon     to the infrastructure where Oracle Java SE executes to compromise Oracle Java SE. While the vulnerability is     in Oracle Java SE, attacks may significantly impact additional products (scope change). (CVE-2026-91484)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of     Oracle Java SE (component: 2D). Supported versions that are affected are Oracle Java SE: 8u503, 8u503-perf,     11.0.32.1, 17.0.20.1, 21.0.12.1, 25.0.4.1, 27; Oracle GraalVM for JDK: 17.0.20.1 and 21.0.12.1; Oracle     GraalVM Enterprise Edition: 21.3.19.1.1. 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 as well as unauthorized update, insert or delete access to some of     Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data and unauthorized     read access to a subset of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition     accessible data. (CVE-2026-91415)

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