Hi, Thanks for providing the capture. A quick look with Wireshark 2.2.4 at packet 27 reveal the same problem I assume. When looking at the numbers my first guess would be that the last fragment (in packet 27) isn’t added to the reassembled payload before being passed to the IPv6 dissector. Therefore the UDPv6 dissector comes up short. I would suggest filing a bug report (https://bugzilla.wireshark.org <https://bugzilla.wireshark.org/>) with this capture file and a proper description, so that it can be investigated further and possibly solved with a code change. Thanks, Jaap

When I attempt to analysis protocol, wireshark said fragemented packet is malformed, but I can't see the why. (Dissecting unfragmented packet is OK.) ................... </snip>
