This is triggered by a malformed PFCP SessionReportRequest on the SMF PFCP (UDP/8805) interface. No known upstream fix is available, but some workarounds are available. ACL/firewall the PFCP interface so only trusted UPF IPs can reach SMF (reduce spoofing/abuse surface); drop/inspect malformed PFCP SessionReportRequest messages at the network edge where feasible, and/or add recover() around PFCP handler dispatch to avoid whole-process termination (mitigation only)."}, {"lang": "es", "value": "free5GC SMF proporciona la Funci\u00f3n de Gesti\u00f3n de Sesiones para free5GC, un proyecto de c\u00f3digo abierto para redes centrales m\u00f3viles de quinta generaci\u00f3n (5G).
