Wireshark 4.6.6 addresses several security and stability issues discovered during fuzz testing — most notably a ROHC dissector crash (wnpa-sec-2026-51) that can be triggered by malformed packets or crafted pcap files and a MACsec global-buffer-overflow (Issue 21235) — while also resolving multiple Windows compatibility, file reader, and packaging regressions and updating bundled Npcap to 1.88.
