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

  - f2fs: fix to do sanity check on total_data_blocks As Yanming reported in bugzilla:
    https://bugzilla.kernel.org/show_bug.cgi?id=215916 The kernel message is shown below: kernel BUG at     fs/f2fs/segment.c:2560!

    ckpt.valid_block_count is inconsistent with SIT table, stat info indicates filesystem has free blocks, but     SIT table indicates filesystem has no free segment. So that during garbage colloection, it triggers panic     when LFS allocator fails to find free segment. This patch tries to fix this issue by checking consistency     in between ckpt.valid_block_count and block accounted from SIT. (CVE-2022-49360)

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-2025-989219 advisory.

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