Descriptions
The dvb_frontend_free function in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel through 4.13.11 allows local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device. NOTE: the function was later renamed __dvb_frontend_free.
La función dvb_frontend_free en drivers/media/dvb-core/dvb_frontend.c en el kernel de Linux, en versiones hasta la 4.13.11, permite que los usuarios locales provoquen una denegación de servicio (uso de memoria previamente liberada y cierre inesperado del sistema) o, posiblemente, causen otros impactos no especificados mediante un dispositivo USB manipulado. NOTA: la función fue posteriormente renombrada como __dvb_frontend_free.
The dvb frontend management subsystem in the Linux kernel contains a use-after-free which can allow a malicious user to write to memory that may be assigned to another kernel structure. This could create memory corruption, panic, or possibly other side affects.
