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

  - ksmbd: pin conn during async oplock break notification smb2_oplock_break_noti() and     smb2_lease_break_noti() store a ksmbd_conn pointer in an async ksmbd_work and then queue that work on     ksmbd-io. The work only increments conn->r_count, which prevents teardown from passing the pending-request     wait after the increment, but it does not pin the struct ksmbd_conn object. If connection teardown races     with an oplock break notification, the last conn reference can be dropped before the queued worker     finishes. The worker then uses the freed conn in ksmbd_conn_write() and ksmbd_conn_r_count_dec(). Take a     real conn reference when publishing the conn pointer to the async work item, and drop it after the     notification work has decremented r_count. Apply the same lifetime rule to lease break notification, which     uses the same work->conn pattern. (CVE-2026-68381)

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