CVE-2022-3190Network attack vector

Analysis hang via F5 trailer infinite loop

Published Sep 13, 2022 · Updated Nov 3, 2025

Infinite loop in Wireshark F5 Ethernet Trailer dissector 3.6.0–3.6.7 and 3.4.0–3.4.15 allows remote attackers to hang analysis via packets. The dissector fails to advance while processing a malformed F5 Ethernet Trailer, creating an infinite loop that consumes excessive CPU. Packet injection requires network reachability to a capture interface, while crafted capture files require convincing a user to open them; the bounded impact is denial of service of Wireshark analysis.
