CVE-2009-4895

Estado: ModificadaMedia (4.7)—

Condición de carrera en la función tty_fasync en drivers/char/tty_io.c en el kernel de Linux v2.6.32.6, permite a usuarios locales provocar una denegación de servicio (deferencia puntero nulo o caída del sistema) o posiblemente tener otro impacto no especificado a través de vectores desconocidos, relacionado con las funciones put_tty_queue y __f_setown. NOTA: la vulnera fue dirigida de un modo distinto en v2.6.32.9.
