CVE-2010-0623

Estado: ModificadaMedia (4.9)—

La función futex_lock_pi en kernel/futex.c en el kernel de Linux anterior a 2.6.33-rc7 no maneja adecuadamente determinadas cuentas de referencia, lo que permite a usuarios locales provocar una denegación de servicio (OOPS) a través de vectores que involucran el desmontado del sistema de ficheros ext3.
