CVE-2010-4343

Estado: ModificadaMedia (5.5)—

drivers/scsi/AMB/bfa_core.c en el kernel de Linux anterior a v2.6.35 no inicializa una estructura de datos en un determinado puerto, lo que permite a usuarios locales causar una denegación de servicio (caída del sistema) a través de las operaciones de lectura en un fichero de estadísticas fc_host.
