      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: uvc: fix dangling pointers in uvc_function_bind() and uvc_function_unbind()\n\nIn uvc_function_bind() error path, we use usb_ep_free_request which\nuses uvc->control_req but does not set it to NULL afterwards. Thus,\nuvc->control_req is a dangling pointer causing a UAF. Also we do not set\nthe uvc->control_buf pointer to NULL after freeing it, which is another\ndangling pointer. Fix it by setting uvc->control_req to NULL after we run\nusb_ep_free_request() and uvc->control_buf to NULL after kfree. Do the\nsame for uvc_function_unbind().",
