The federal response to the recently revealed “Meltdown” and “Spectre” computer chip vulnerabilities, requiring a massive “patch” to public and private systems, is earning rare high marks from lawmakers and industry sources.

Federal officials are unlikely to mandate private-sector actions related to the vulnerabilities discovered in chips made by Intel, Advanced Micro Devices, and ARM Holdings, but rather are playing an information-sharing and supportive role, according to government and private-sector sources who said this is the appropriate response.
