CVE-2025-65565

A denial-of-service vulnerability exists in the omec-project UPF (pfcpiface component) in version upf-epc-pfcpiface:2.1.3-dev. After PFCP association is established, a PFCP Session Establishment Request that is missing the mandatory F-SEID (CPF-SEID) Information Element is not properly validated. The session establishment handler calls IE.FSEID() on a nil pointer, which triggers a panic and terminates the UPF process. An attacker who can send PFCP Session Establishment 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 pfcpiface) en la versión upf-epc-pfcpiface:2.1.3-dev. Después de que se establece la asociación PFCP, una Solicitud de Establecimiento de Sesión PFCP a la que le falta el Elemento de Información F-SEID (CPF-SEID) obligatorio no se valida correctamente. El gestor de establecimiento de sesión llama a IE.FSEID() en un puntero nulo, lo que desencadena un pánico y termina el proceso UPF. Un atacante que puede enviar mensajes de Solicitud de Establecimiento de Sesión PFCP al punto final N4/PFCP del UPF puede explotar este problema para bloquear repetidamente el UPF e interrumpir los servicios del plano de usuario.
