CVE-2018-19023
This can lead to unauthorized replay of a command, spoofing of an arbitrary message, or keeping the controlled load in a permanent "stop" state.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.75%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
