CVE-2015-1465

Estado: ModificadaAlta (7.8)—

La implementación IPv4 en el kernel de Linux anterior a 3.18.8 no considera correctamente la longitud del periodo de gracia de Read-Copy Update (RCU) para redirigir búsquedas en la ausencia de cacheo, lo que permite a atacantes remotos causar una denegación de servicio (corrupción de memoria o caída de sistema) a través de una inundación de paquetes.
