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

  - When verifying a certificate chain containing excluded DNS constraints, these constraints are not     correctly applied to wildcard DNS SANs which use a different case than the constraint. This only affects     validation of otherwise trusted certificate chains, issued by a root CA in the VerifyOptions.Roots     CertPool, or in the system certificate pool. (CVE-2026-33810)

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