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

  - selinux: use sk blob accessor in socket permission helpers SELinux socket state lives in the composite LSM     socket blob. sock_has_perm() and nlmsg_sock_has_extended_perms() currently dereference sk->sk_security     directly, which assumes the SELinux socket blob is at offset zero. In stacked configurations that     assumption does not hold. If another LSM allocates socket blob storage before SELinux, these helpers may     read the wrong blob and feed invalid SID and class values into AVC checks. Use selinux_sock() instead of     accessing sk->sk_security directly. (CVE-2026-46104)

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