CVE-2026-5299: CWE-674: Uncontrolled Recursion in Wireshark Foundation Wireshark
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
AI Analysis
Technical Summary
This vulnerability (CVE-2026-5299) affects the Wireshark network protocol analyzer in specific versions (4.6.0 to 4.6.4 and 4.4.0 to 4.4.14). It is caused by uncontrolled recursion within the ICMPv6 PvD protocol dissector, which can lead to a crash of the application and thus a denial of service condition. The CVSS v3.1 base score is 5.5, reflecting a medium severity with local attack vector, low attack complexity, no privileges required, user interaction required, and impact limited to availability. No official fix or patch has been documented in the provided data, and no known exploits have been reported.
Potential Impact
Successful exploitation causes a denial of service by crashing Wireshark when processing malicious ICMPv6 PvD packets. There is no impact on confidentiality or integrity. The attack requires local access and user interaction, limiting the scope of exploitation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid opening untrusted ICMPv6 PvD traffic in affected Wireshark versions. Monitor official Wireshark Foundation communications for updates on patches or mitigations.
