Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且廠商未提供可用的修補程式。

  - powercap: intel_rapl修正 UBSAN shift-out-of-bounds 問題當 value < time_unit 時ilog2() 的參數將會為零且傳回值為 -1。 u64(-1) 對於移位指數而言太大然後將觸發移位超出邊界移位指數 18446744073709551615 對於 32 位元類型「int」呼叫追踪太大

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-992177 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    powercap: intel_rapl: fix UBSAN shift-out-of-bounds issue

    When value < time_unit, the parameter of ilog2() will be zero and     the return value is -1. u64(-1) is too large for shift exponent     and then will trigger shift-out-of-bounds:

    shift exponent 18446744073709551615 is too large for 32-bit type 'int'     Call Trace:
     rapl_compute_time_window_core      rapl_write_data_raw      set_time_window      store_constraint_time_window_us

Tenable has extracted the preceding description block directly from the Unity 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.

An update of the linux package has been released.

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