Description Johannes Segitz 2017-11-06 15:52:35 UTC 
rh#1505905

Race condition in legousbtower driver exposes a null pointer dereference caused by not removing the device file interface on an error when the probe function is called. This can cause a write-what-where condition by remapping dev->interrupt_out_buffer in tower_write, leading to privilege escalation.
