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

  - 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. (CVE-2023-52748)

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-2025-989419 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:

    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.
