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

  - apparmor: fix unprivileged local user can do privileged policy management An unprivileged local user can     load, replace, and remove profiles by opening the apparmorfs interfaces, via a confused deputy attack, by     passing the opened fd to a privileged process, and getting the privileged process to write to the     interface. This does require a privileged target that can be manipulated to do the write for the     unprivileged process, but once such access is achieved full policy management is possible and all the     possible implications that implies: removing confinement, DoS of system or target applications by denying     all execution, by-passing the unprivileged user namespace restriction, to exploiting kernel bugs for a     local privilege escalation. The policy management interface can not have its permissions simply changed     from 0666 to 0600 because non-root processes need to be able to load policy to different policy     namespaces. Instead ensure the task writing the interface has privileges that are a subset of the task     that opened the interface. This is already done via policy for confined processes, but unconfined can     delegate access to the opened fd, by-passing the usual policy check. (CVE-2026-23268)

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