  "details": "In the Linux kernel, the following vulnerability has been resolved:  usb: gadget: uvc: clamp SEND_RESPONSE length to the response buffer  uvc_send_response() builds the UVC control response from a user-supplied struct uvc_request_data:  \treq-\u003elength = min_t(unsigned int, uvc-\u003eevent_length, data-\u003elength); \t... \tmemcpy(req-\u003ebuf, data-\u003edata, req-\u003elength);  req-\u003elength is clamped to uvc-\u003eevent_length, which is taken from the host control request wLength (up to UVC_MAX_REQUEST_SIZE, 64), and to data-\u003elength, which comes from the UVCIOC_SEND_RESPONSE ioctl and is only checked for being negative.  The source buffer data-\u003edata is only 60 bytes, so a response with uvc-\u003eevent_length and data-\u003elength both greater than 60 makes memcpy() read past the end of data-\u003edata.  Clamp req-\u003elength to sizeof(data-\u003edata) as well.",
