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。

  - kernel/fail_function使用 debugfs_lookup() 修正記憶體洩漏。呼叫 debugfs_lookup() 時結果必須有呼叫 dput() 否則記憶體會隨著時間推移而洩漏。為使事情變得更簡單只要呼叫 debugfs_lookup_and_remove() 而不是它會立即處理所有邏輯。 (CVE-2023-53346)

請注意，Nessus 依賴供應商報告的套件存在。

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。

  - kernel/fail_function使用 debugfs_lookup() 修复内存泄漏调用 debugfs_lookup() 时结果必须调用 dput() 否则内存将随着时间泄漏。要使事情更简单只需调用 debugfs_lookup_and_remove()其会同时处理所有逻辑。 (CVE-2023-53346)

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。

  - kernel/fail_functiondebugfs_lookup() を使用した場合のメモリリークを修正します。debugfs_lookup() を呼び出す場合、結果には dput() が呼び出される必要があります。そうしないと、メモリは時間とともにリークします。そうするためには、すべてのロジックを一度に処理する代わりに、debugfs_lookup_and_remove() を呼び出すだけで済みます。CVE-2023-53346

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

  - kernel/fail_function: fix memory leak with using debugfs_lookup() When calling debugfs_lookup() the result     must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call     debugfs_lookup_and_remove() instead which handles all of the logic at once. (CVE-2023-53346)

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-992536 advisory.

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

    kernel/fail_function: fix memory leak with using debugfs_lookup()

    When calling debugfs_lookup() the result must have dput() called on it,     otherwise the memory will leak over time.  To make things simpler, just     call debugfs_lookup_and_remove() instead which handles all of the logic     at once.

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.
