CVE-2025-65568

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, a PFCP Session Establishment Request that includes a CreateFAR with an empty or truncated IPv4 address field is not properly validated. During parsing, parseFAR() calls ip2int(), which performs an out-of-bounds read on the IPv4 address buffer and triggers an index-out-of-range panic. 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 la asociación PFCP, una solicitud de establecimiento de sesión PFCP que incluye un CreateFAR con un campo de dirección IPv4 vacío o truncado no se valida correctamente. Durante el análisis, parseFAR() llama a ip2int(), que realiza una lectura fuera de límites en el búfer de dirección IPv4 y desencadena un pánico por índice fuera de rango. 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.
