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

  - rxrpc: Fix recvmsg() unconditional requeue If rxrpc_recvmsg() fails because MSG_DONTWAIT was specified but     the call at the front of the recvmsg queue already has its mutex locked, it requeues the call - whether or     not the call is already queued. The call may be on the queue because MSG_PEEK was also passed and so the     call was not dequeued or because the I/O thread requeued it. The unconditional requeue may then corrupt     the recvmsg queue, leading to things like UAFs or refcount underruns. Fix this by only requeuing the call     if it isn't already on the queue - and moving it to the front if it is already queued. If we don't queue     it, we have to put the ref we obtained by dequeuing it. Also, MSG_PEEK doesn't dequeue the call so     shouldn't call rxrpc_notify_socket() for the call if we didn't use up all the data on the queue, so fix     that also. (CVE-2026-23066)

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