Nessus は、ベンダーによって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 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-2022-47943 advisory.

  - An issue was discovered in ksmbd in the Linux kernel 5.15 through 5.19 before 5.19.2. There is an out-of-     bounds read and OOPS for SMB2_WRITE, when there is a large length in the zero DataOffset case.
    (CVE-2022-47943)

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-010702 advisory.
