CVE-2026-45762
Description
A flaw was found in Suricata, a network Intrusion Detection System. The IP defragmentation tracker lookup did not properly verify the IP address family of incoming packets. A remote attacker could send specially crafted fragmented IPv4/IPv6 traffic, causing an IPv6 fragment to be incorrectly associated with an IPv4 defragmentation tracker. This could lead to a crash and a denial of service when Suricata processes the fragmented packets.
