    Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

    CVE-2026-41254:
    Little CMS (lcms2) through 2.18 has an integer overflow in CubeSize in cmslut.c because the overflow check
    is performed after the multiplication.

    CVE-2026-46968:
    Vulnerability in Oracle Java SE (component: JSSE).  Supported versions that are affected are Oracle Java
    SE: 8u491, 8u491-perf, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1; Oracle GraalVM for JDK: 17.0.19 and
    21.0.11; Oracle GraalVM Enterprise Edition: 21.3.18. Difficult to exploit vulnerability allows
    unauthenticated attacker with network access via TLS to compromise Oracle Java SE.  Successful attacks of
    this vulnerability can result in  unauthorized creation, deletion or modification access to critical data
    or all Oracle Java SE accessible data. Note: This vulnerability can only be exploited by supplying data to
    APIs in the specified Component without using Untrusted Java Web Start applications or Untrusted Java
    applets, such as through a web service. CVSS 3.1 Base Score 5.9 (Integrity impacts).  CVSS Vector:
    (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N).

    Oracle GraalVM Enterprise Edition: 21.3.18. 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 of this vulnerability can result in  unauthorized
    update, insert or delete access to some of 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 3.7 (Integrity impacts).  CVSS Vector:
    (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N).

    CVE-2026-47021:
    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: 8u491,
    8u491-perf, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1; Oracle GraalVM for JDK: 17.0.19 and  21.0.11;
    Oracle GraalVM Enterprise Edition: 21.3.18. 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 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. CVSS 3.1 Base Score 5.3 (Availability impacts).  CVSS Vector:
    (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).

    CVE-2026-47027:

    CVE-2026-47057:
    Vulnerability in Oracle Java SE (component: Scripting).  Supported versions that are affected are Oracle
    Java SE: 8u491, 8u491-perf and  11.0.31. Easily exploitable vulnerability allows unauthenticated attacker
    with network access via multiple protocols to compromise Oracle Java SE.  Successful attacks of this
    vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete
    DOS) of Oracle Java SE. Note: This vulnerability can be exploited by using APIs in the specified
