What the advisory describes

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: printer: fix infinite loop in printer_read() printer_read() uses the same variable for the requested copy size and the number of bytes actually copied to user space. copy_to_user() returns the number of bytes not copied, so when it fails to copy anything, the computed copied length becomes zero. In that case len, buf, current_rx_bytes and current_rx_buf are left unchanged. If RX data is available and the user buffer remains unwritable, the read loop can repeat indefinitely. Track the copied length separately and return -EFAULT, or the number of bytes already copied, if an iteration makes no progress.

Source: EUVD (ENISA), in the words of the advisory.
