CVE-2017-8072
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.41%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
