In the Linux kernel, the following vulnerability has been resolved:
serial: mxs-auart: add spinlock around changing cts state
The uart_handle_cts_change() function in serial_core expects the caller
to hold uport->lock. For example, I have seen the below kernel splat,
when the Bluetooth driver is loaded on an i.MX28 board.
