Nessus は、ベンダーから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-2025-989419 advisory.

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

    f2fs: avoid format-overflow warning

    With gcc and W=1 option, there's a warning like this:

    fs/f2fs/compress.c: In function f2fs_init_page_array_cache:
    fs/f2fs/compress.c:1984:47: error: %u directive writing between     1 and 7 bytes into a region of size between 5 and 8     [-Werror=format-overflow=]      1984 |  sprintf(slab_name, f2fs_page_array_entry-%u:%u, MAJOR(dev),                     MINOR(dev));
          |                                               ^~

    String f2fs_page_array_entry-%u:%u can up to 35. The first %u can up     to 4 and the second %u can up to 7, so total size is 24 + 4 + 7 = 35.
    slab_name's size should be 35 rather than 32.

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 Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-989693 advisory.
