## Description

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.  [  361.894299] [1:   irq/191-dwc3:16979] list_add corruption. next->prev should be prev (ffffff80651764d0), but was ffffff883dc36f80. (next=ffffff80651764d0).
