Summary

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

usb: gadget: rndis: add spinlock for rndis response list

There's no lock for rndis response list. It could cause list corruption if there're two different list_add at the same time like below. It's better to add in rndis_add_response / rndis_free_response / rndis_get_next_response to prevent any race condition on response list.
