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-2026-013178 advisory.

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

    f2fs: fix to drop all dirty pages during umount() if cp_error is set

    xfstest generic/361 reports a bug as below:

    f2fs_bug_on(sbi, sbi->fsync_node_num);

    kernel BUG at fs/f2fs/super.c:1627!     RIP: 0010:f2fs_put_super+0x3a8/0x3b0     Call Trace:

    During umount(), if cp_error is set, f2fs_wait_on_all_pages() should     not stop waiting all F2FS_WB_CP_DATA pages to be writebacked, otherwise,     fsync_node_num can be non-zero after f2fs_wait_on_all_pages() causing     this bug.

    In this case, to avoid deadloop in f2fs_wait_on_all_pages(), it needs     to drop all dirty pages rather than redirtying them.

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.

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

In this case, to avoid deadloop in     f2fs_wait_on_all_pages(), it needs to drop all dirty pages rather than redirtying them. (CVE-2023-54124)

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