Descriptions

drivers/hid/hid-cp2112.c in the Linux kernel 4.9.x before 4.9.9 uses a spinlock without considering that sleeping is possible in a USB HID request callback, which allows local users to cause a denial of service (deadlock) via unspecified vectors.

drivers/hid/hid-cp2112.c en el kernel de Linux 4.9.x en versiones anteriores a 4.9.9 utiliza un spinlock sin considerar que es posible el sleeping en una solicitud de devolución de llamada en HID USB, lo que permite a los usuarios locales provocar una denegación de servicio (punto muerto) a través de vectores no especificados.
