CVE-2026-15163 is an infinite-loop vulnerability affecting the MIH, MPEG DSM-CC, eDonkey, and MEGACO protocol dissectors in Wireshark 4.6.0 through 4.6.6 and 4.4.0 through 4.4.16. Malformed protocol data can cause dissector parsing loops to fail to advance their input offset, resulting in repeated processing of the same data. The affected loops include MPEG DSM-CC resource parsing, eDonkey list parsing, and MIH handling of an unknown link-address type.
