Vulnerability from fkie_nvd - Published: 2026-02-23 22:16 - Updated: 2026-02-25 16:20
Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
free5GC is an open-source project for 5th generation (5G) mobile core networks. free5GC go-upf versions up to and including 1.2.6, corresponding to free5gc smf up to and including 1.4.0, have an Improper Input Validation and Protocol Compliance vulnerability leading to Denial of Service. Remote attackers can disrupt core network functionality by sending a malformed PFCP Association Setup Request. The UPF incorrectly accepts it, entering an inconsistent state that causes subsequent legitimate requests to trigger SMF reconnection loops and service degradation. All deployments of free5GC using the UPF and SMF components may be affected. As of time of publication, a fix is in development but not yet available. No direct workaround is available at the application level. Applying the official patch, once released, is recommended.

Los atacantes remotos pueden interrumpir la funcionalidad de la red de n\u00facleo enviando una Solicitud de Configuraci\u00f3n de Asociaci\u00f3n PFCP malformada. El UPF la acepta incorrectamente, entrando en un estado inconsistente que causa que las solicitudes leg\u00edtimas subsiguientes activen bucles de reconexi\u00f3n del SMF y degradaci\u00f3n del servicio. Todas las implementaciones de free5GC que utilizan los componentes UPF y SMF pueden verse afectadas. En el momento de la publicaci\u00f3n, se est\u00e1 desarrollando una correcci\u00f3n pero a\u00fan no est\u00e1 disponible. No hay una soluci\u00f3n alternativa directa disponible a nivel de aplicaci\u00f3n. Se recomienda aplicar el parche oficial, una vez lanzado."
