FKIE_CVE-2025-65564

Vulnerability from fkie_nvd - Published: 2025-12-18 19:16 - 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-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.

Cuando el UPF recibe una solicitud de configuraci\u00f3n de asociaci\u00f3n PFCP a la que le falta el elemento de informaci\u00f3n obligatorio \u0027Recovery Time Stamp\u0027, el gestor de configuraci\u00f3n de asociaci\u00f3n desreferencia un puntero nulo a trav\u00e9s de IE.RecoveryTimeStamp() en lugar de validar el mensaje.
