CVE-2007-5938

Estado: ModificadaMedia (5)—

La función iwl_set_rate en compatible/iwl3945-base.c de iwlwifi 1.1.21 y anteriores hace referencia a un valor de retorno de iwl_get_hw_mode sin comprobar si es NULL, lo cual podría permitir a atacantes remotos provocar una denegación de servicio (error irrecuperable del sistema) mediante vectores no especificados durante la inicialización del módulo.
