CVE-2025-65563

A denial-of-service vulnerability exists in the omec-project UPF (component upf-epc/pfcpiface) up to at least version upf-epc-pfcpiface:2.1.3-dev. When the UPF receives a PFCP Association Setup Request that is missing the mandatory NodeID Information Element, the association setup handler dereferences a nil pointer instead of validating the message, causing a panic and terminating the UPF process. An attacker who can send PFCP Association Setup Request messages to the UPF's N4/PFCP endpoint can exploit this issue to repeatedly crash the UPF and disrupt user-plane services.

Summary		(es) Una vulnerabilidad de denegación de servicio existe en el UPF del proyecto omec (componente upf-epc/pfcpiface) hasta al menos la versión upf-epc-pfcpiface:2.1.3-dev. Cuando el UPF recibe una solicitud de establecimiento de asociación PFCP a la que le falta el elemento de información NodeID obligatorio, el gestor de establecimiento de asociación desreferencia un puntero nulo en lugar de validar el mensaje, lo que provoca un pánico y la terminación del proceso del UPF. Un atacante que puede enviar mensajes de solicitud de establecimiento de asociación PFCP al punto final N4/PFCP del UPF puede explotar este problema para bloquear repetidamente el UPF y perturbar los servicios del plano de usuario.
