CVE-2020-11492
If a local attacker sets up their own named pipe prior to starting Docker with the same name, this attacker can intercept a connection attempt from Docker Service (which runs as SYSTEM), and then impersonate their privileges.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.94%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
