Rejected reason: ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn by its CNA. Further investigation showed that it was not a security issue. Notes: Based on the analysis by MITRE and review of community feedback, the reported conditions represent expected and intentional behavior within dnsmasq's documented design, rather than security vulnerabilities.
