AI-suggested
Upgrade Suricata to version 8.0.5 or later, where the deadlock issue in IP defragmentation is fixed. No known workarounds are available, so patching is the recommended remediation.
Description
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Starting in version 8.0.0 and prior to version 8.0.5, Suricata's IP defragmentation code could deadlock when processing fragmented traffic containing an encapsulated tunnel protocol whose payload is itself fragmented. Version 8.0.5 contains a fix. No known workarounds are available.
