CVE-2025-65564

A denial-of-service vulnerability exists in the omec-upf (upf-epc-pfcpiface) in version upf-epc-pfcpiface:2.1.3-dev. When the UPF receives a PFCP Association Setup Request that is missing the mandatory Recovery Time Stamp Information Element, the association setup handler dereferences a nil pointer via IE.RecoveryTimeStamp() instead of validating the message. This results in a panic and terminates 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) Existe una vulnerabilidad de denegación de servicio en el omec-upf (upf-epc-pfcpiface) en la versión upf-epc-pfcpiface:2.1.3-dev. Cuando el UPF recibe una solicitud de configuración de asociación PFCP a la que le falta el elemento de información obligatorio 'Recovery Time Stamp', el gestor de configuración de asociación desreferencia un puntero nulo a través de IE.RecoveryTimeStamp() en lugar de validar el mensaje. Esto resulta en un pánico y termina el proceso del UPF. Un atacante que puede enviar mensajes de solicitud de configuración 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.
