Description Adam Mariš 2017-04-25 13:45:44 UTC 
The cp2112_gpio_direction_input function in drivers/hid/hid-cp2112.c
in the Linux kernel 4.9.x before 4.9.9 does not have the expected EIO
error status for a zero-length report, which allows local users to
have an unspecified impact via unknown vectors.
