CVE-2026-5299 Details
Description
ICMPv6 PvD protocol dissector crash in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service
A denial-of-service vulnerability has been identified in the Wireshark ICMPv6 protocol dissector, specifically in versions 4.6.0 through 4.6.4 and 4.4.0 through 4.4.14. The issue arises from the PvD ID option handler, which recursively processes nested options in a way that leads to exponential growth in processing time and memory usage. This can cause Wireshark to hang and consume excessive resources until the process is terminated.
Users are advised to upgrade to Wireshark versions 4.6.5, 4.4.15 or later.
