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

  - An issue was discovered in ksmbd in the Linux kernel 5.15 through 5.19 before 5.19.2. fs/ksmbd/smb2pdu.c     omits a kfree call in certain smb2_handle_negotiate error conditions, aka a memory leak. (CVE-2022-47941)

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-2026-013443 advisory.

    An issue was discovered in ksmbd in the Linux kernel 5.15 through 5.19 before 5.19.2. fs/ksmbd/smb2pdu.c     omits a kfree call in certain smb2_handle_negotiate error conditions, aka a memory leak.

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 version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-47941 advisory.

    (CVE-2022-47939)

  - An authenticated remote code execution vulnerability in the ksmbd component of the Linux kernel.
    (CVE-2022-47942)

  - An unauthenticated remote denial of service vulnerability in the ksmbd component of the Linux     kernel. (CVE-2022-47941)

  - Authenticated denial of service vulnerabilities in the ksmbd component of the Linux kernel.
    (CVE-2022-47938, CVE-2022-47940)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
