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

  - In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix NULL deref in     ntfs_update_mftmirr If ntfs_fill_super() wasn't called then sbi->sb will be equal to NULL. Code should     check this ptr before dereferencing. Syzbot hit this issue via passing wrong mount param as can be seen     from log below Fail log: ntfs3: Unknown parameter 'iochvrset' general protection fault, probably for non-     canonical address 0xdffffc0000000003: 0000 [#1] PREEMPT SMP KASAN KASAN: null-ptr-deref in range     [0x0000000000000018-0x000000000000001f] CPU: 1 PID: 3589 Comm: syz-executor210 Not tainted     5.18.0-rc3-syzkaller-00016-gb253435746d9 #0 ...

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-2026-131747 advisory.

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

    fs/ntfs3: Fix NULL deref in ntfs_update_mftmirr

    If ntfs_fill_super() wasn't called then sbi->sb will be equal to NULL.
    Code should check this ptr before dereferencing. Syzbot hit this issue     via passing wrong mount param as can be seen from log below

    Fail log:

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.
