Descriptions

In the Linux kernel, the following vulnerability has been resolved:

HID: betop: fix slab-out-of-bounds Write in betop_probe

Syzbot reported slab-out-of-bounds Write bug in hid-betopff driver.
The problem is the driver assumes the device must have an input report but
some malicious devices violate this assumption.

So this patch checks hid_device's input is non empty before it's been used.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: HID: betop: corrige escritura slab-out-of-bounds en betop_probe. Syzbot informó un error de escritura slab-out-of-bounds en el controlador hid-betopff. El problema es que el controlador supone que el dispositivo debe tener un informe de entrada, pero algunos dispositivos maliciosos violan esta suposición. Entonces, este parche verifica que la entrada de hid_device no esté vacía antes de usarse.
