CVE-2026-27828

EVerest is an EV charging software stack. Prior to version 2026.02.0, ISO15118_chargerImpl::handle_session_setup uses v2g_ctx after it has been freed when ISO15118 initialization fails (e.g., no IPv6 link-local address). The EVSE process can be crashed remotely by an attacker with MQTT access who issues a session_setup command while v2g_ctx has been released. Version 2026.02.0 contains a patch.

Summary		(es) EVerest es una pila de software de carga de vehículos eléctricos. Antes de la versión 2026.02.0, ISO15118_chargerImpl::handle_session_setup utiliza v2g_ctx después de que ha sido liberado cuando la inicialización de ISO15118 falla (p. ej., no hay dirección IPv6 link-local). El proceso EVSE puede ser colapsado remotamente por un atacante con acceso MQTT que emite un comando session_setup mientras v2g_ctx ha sido liberado. La versión 2026.02.0 contiene un parche.
