Hi,
We are writing to report the results of a recent analysis we conducted on the DHCPv6 implementation in dnsmasq. Our work focused on verifying its compliance against the most recent DHCPv6 specification, RFC 8415.
During our analysis, we identified dozens of instances where the implementation's behavior deviates from the mandatory requirements of the RFC. While many of these are minor protocol non-compliances, several have potential security implications that we believe warrant a high-priority review.
Due to the number of findings, we have compiled a comprehensive report detailing each issue, which is provided as an attachment to this email. We hope this report is helpful.
Best regards,
Xiangpu Song
