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

  - f2fs修正 f2fs_move_inline_dirents() 中的資訊洩漏。將內嵌目錄轉換為一般目錄時f2fs 未初始化整個目錄區塊因此將未初始化的記憶體洩漏至磁碟。藉由零初始化區塊來修正此問題。此錯誤是由認可 4ec17d688d74 (f2fs
    避免在轉換內嵌 dentry 時發生不需要的初始化)其未考慮將未初始化記憶體洩漏至磁碟的安全性影響。這是在支援 KMSAN 的核心上執行 xfstest generic/435 所發現的。 (CVE-2023-53796)

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。

  - f2fs修复 f2fs_move_inline_dirents() 中的信息泄漏。将内联目录转换为常规目录时f2fs 会将未初始化的内存泄漏到磁盘因为它不会初始化整个目录块。通过对该区块进行零初始化来修复此问题。此缺陷由提交 4ec17d688d74f2fs
    避免转换内联 dentry 时不必要的初始化其未考虑将未初始化的内存泄漏到磁盘所造成的安全影响。是通过在启用了 KMSAN 的内核上运行 xfstest generic/435 发现的。 (CVE-2023-53796)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-010968 advisory.

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

    f2fs: fix information leak in f2fs_move_inline_dirents()

    When converting an inline directory to a regular one, f2fs is leaking     uninitialized memory to disk because it doesn't initialize the entire     directory block.  Fix this by zero-initializing the block.

    This bug was introduced by commit 4ec17d688d74 (f2fs: avoid unneeded     initializing when converting inline dentry), which didn't consider the     security implications of leaking uninitialized memory to disk.

    This was found by running xfstest generic/435 on a KMSAN-enabled kernel.

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.
