FKIE_CVE-2025-65566

Vulnerability from fkie_nvd - Published: 2025-12-18 20:16 - Updated: 2026-10-13 11:10
Severity
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
A denial-of-service vulnerability exists in the omec-project UPF (pfcpiface component) in version upf-epc-pfcpiface:2.1.3-dev. When the UPF receives a PFCP Session Report Response that is missing the mandatory Cause Information Element, the session report handler dereferences a nil pointer instead of rejecting the malformed message. This triggers a panic and terminates the UPF process. An attacker who can send PFCP Session Report Response messages to the UPF's N4/PFCP endpoint can exploit this flaw to repeatedly crash the UPF and disrupt user-plane services.

Cuando el UPF recibe una respuesta de informe de sesi\u00f3n PFCP a la que le falta el elemento de informaci\u00f3n de causa obligatorio, el gestor de informes de sesi\u00f3n desreferencia un puntero nulo en lugar de rechazar el mensaje malformado. Esto desencadena un p\u00e1nico y termina el proceso del UPF. Un atacante que puede enviar mensajes de respuesta de informe de sesi\u00f3n PFCP al punto final N4/PFCP del UPF puede explotar esta falla para bloquear repetidamente el UPF y perturbar los servicios del plano de usuario."
