Intel revealed Vulnerability-related.DiscoverVulnerability that it will not be issuing Vulnerability-related.PatchVulnerability Spectre patches to a number of older Intel processor families , potentially leaving many customers vulnerable to the security exploit . Intel claims the processors affected are mostly implemented as closed systems , so they aren ’ t at risk from the Spectre exploit , and that the age of these processors means they have limited commercial availability . The processors which Intel won ’ t be patching Vulnerability-related.PatchVulnerability include four lines from 2007 , Penryn , Yorkfield , and Wolfdale , along with Bloomfield ( 2009 ) , Clarksfield ( 2009 ) , Jasper Forest ( 2010 ) and the Intel Atom SoFIA processors from 2015 . According to Tom ’ s Hardware , Intel ’ s decision not to patch Vulnerability-related.PatchVulnerability these products could stem from the relative difficulty of patching Vulnerability-related.PatchVulnerability the Spectre exploit on older systems . “ After a comprehensive investigation of the microarchitectures and microcode capabilities for these products , Intel has determined to not release Vulnerability-related.PatchVulnerability microcode updates for these products , ” Intel said . Because of the nature of the Spectre exploit , patches for it need to be delivered Vulnerability-related.PatchVulnerability as an operating system or BIOS update , and if Microsoft and motherboard OEMs aren ’ t going to distribute Vulnerability-related.PatchVulnerability the patches , developing Vulnerability-related.PatchVulnerability them isn ’ t much of a priority . “ However , the real reason Intel gave up on patching Vulnerability-related.PatchVulnerability these systems seems to be that neither motherboard makers nor Microsoft may be willing to update Vulnerability-related.PatchVulnerability systems sold a decade ago , ” Tom ’ s Hardware reports . It sounds bad , but as Intel pointed out , these are all relatively old processors — with the exception of the Intel Atom SoFIA processor , which came out in 2015 — and it ’ s unlikely they ’ re used in any high-security environments . The Spectre exploit is a serious security vulnerability to be sure , but as some commentators have pointed out in recent months , it ’ s not the kind of exploit the average user needs to worry about . “ We ’ ve now completed release Vulnerability-related.PatchVulnerability of microcode updates for Intel microprocessor products launched in the last 9+ years that required protection against the side-channel vulnerabilities discovered Vulnerability-related.DiscoverVulnerability by Google Project Zero , ” said an Intel spokseperson . “ However , as indicated in our latest microcode revision guidance , we will not be providing Vulnerability-related.PatchVulnerability updated microcode for a select number of older platforms for several reasons , including limited ecosystem support and customer feedback. ” If you have an old Penryn processor toiling away in an office PC somewhere , you ’ re probably more at risk for a malware infection arising from a bad download than you are susceptible to something as technically sophisticated as the Spectre or Meltdown vulnerabilities .
