Subject: Fwd: CVE Request: Linux: usbnet: memory corruption triggered by
 invalid USB descriptor

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

> There's a flaw in the usbnet Linux kernel driver:
>
>> usbnet_link_change will call schedule_work and should be
>> avoided if bind is failing. Otherwise we will end up with
>> scheduled work referring to a netdev which has gone away.
>>
>> Instead of making the call conditional, we can just defer
>> it to usbnet_probe, using the driver_info flag made for
>> this purpose.
>
> The bug allows physically proximate attackers to cause a denial of
> service (NULL pointer dereference and system crash) or possibly have
> other impact by inserting a USB device with an invalid USB descriptor.
