Now Meltdown Patches Are Making Industrial Control Systems Lurch (theregister.co.uk)

Patches for the Meltdown vulnerability are causing stability issues in industrial control systems. From a report: SCADA vendor Wonderware admitted that Redmond's Meltdown patch made its Historian product wobble. "Microsoft update KB4056896 (or parallel patches for other Operating System) causes instability for Wonderware Historian and the inability to access DA/OI Servers through the SMC," an advisory on Wonderware's support site explains. Rockwell Automation revealed that the same patch had caused issues with Studio 5000, FactoryTalk View SE, and RSLinx Classic (a widely used product in the manufacturing sector). "In fairness [this] may be RPC [Remote Procedure Call] change related," said cybersecurity vulnerability manager Kevin Beaumont.
