CVE-2020-12523
After a reboot these ports get functional independent from their configuration setting: Missing Initialization of Resource
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.90%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
