CVE-2018-9567
This may lead to local escalation of privilege if people are relying on those fingerprints to determine what version of the OS the device is running, with System execution privileges needed.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.15%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
