What the advisory describes
In the Linux kernel, the following vulnerability has been resolved: usb: mtu3: unmap request DMA on queue failure mtu3_gadget_queue() maps the request before checking whether the QMU GPD ring can accept another transfer. the request is returned with -EAGAIN before it is linked on the endpoint request list if mtu3_prepare_transfer() fails. Normal completion and dequeue paths unmap requests from mtu3_req_complete(), but this error path never reaches that helper, so the DMA mapping is left active. Unmap the request before returning from the failed queue path.
Source: EUVD (ENISA), in the words of the advisory.
