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

  - smb: client: reject short READ responses in CIFSSMBRead() CIFSSMBRead() reads DataLengthHigh, DataLength     and DataOffset out of the READ_RSP returned by the server without first checking that a whole READ_RSP was     actually received. The length of the response is recorded in rsp_iov.iov_len, but nothing constrains it to     be at least read_rsp_size before those fields are dereferenced. A malicious or compromised SMB1 server can     return a response shorter than the READ_RSP header, so that parsing the header itself reads past the end     of the receive buffer. SMB1 is not negotiated by default; reaching this code requires an explicit vers=1.0     mount. Reject the response unless it is at least read_rsp_size bytes long. (CVE-2026-97565)

Note that Nessus relies on the presence of the package as reported by the vendor.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3192 advisory.

    An issue in the Linux kernel's virtio-net/TAP networking path could allow an actor with privileged access     inside a guest virtual machine to send specially crafted network packets that corrupt host kernel memory     on KVM-based hypervisors running unpatched Linux kernel versions 4.4 through 6.18. This could result in     disclosure of host memory or a denial of service.
