    CVE-2026-114820:
    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: 8u511-b32,
    8u511-perf-b32, 11.0.33.0.2, 17.0.21.0.2, 21.0.13.0.2, 25.0.5.0.2, 27.0.1.0.2; Oracle GraalVM for JDK:
    17.0.21.0.2 and 21.0.13.0.2; Oracle GraalVM Enterprise Edition: 21.3.20.0.2. 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 creation, deletion or modification access to critical data or all
    Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data as well as
    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. CVSS 3.1 Base Score 9.1 (Confidentiality and
    Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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