CVE-2026-5299 [MEDIUM] CWE-674 wireshark: Uncontrolled Recursion in Wireshark
wireshark: Uncontrolled Recursion in Wireshark
A flaw was found in the ICMPv6 PvD protocol dissector in Wireshark. This issue occurs when malformed packets are decoded from a pcap file or the network, causing an uncontrolled recursion that leads to an excessive consumption of CPU and memory resources, resulting in a denial of service.
Statement: This issue will cause a crash in Wireshark with no other security impact. Also, this flaw can only be exploited when a malformed pcap file is processed. Due to these reasons, this vulnerability has been rated with a moderate severity.
Mitigation: If the ICMPv6 PvD protocol dissector is not being used, it can be disabled via the "Enabled Protocols" dialog box in the Wireshark GUI application. This will also disable the protocol dissector when usi
