Intel won't patch Spectre v2 flaw in older processors

Haifa team sires Intel's 'best processor ever' for laptops

Intel gets hurt in the process because all of the hardware success of Apple Mac systems over the years have been through Intel CPUs, associated technologies, and innovation.

Most of the chips are older, with some starting production in 2008, and are probably less widely used today than the already patched Kaby Lake, Skylake, and Coffee Lake CPUs.

Despite Mac products dropping Intel chips being the main focus points of news, it was also announced that iPhones and iPads will also stop using them, as part of Apple's larger plan to develop their own chip systems, which is still in the earlier stages of development.

Micro-architectural characteristics that preclude a practical implementation of features mitigating variant 2 CVE-2017-5715.

Those processors that will not receive the firmware update are: Bloomfield, Bloomfield Xeon, Clarksfield, Gulftown, Harpertown Xeon C0 and E0, Jasper Forest, Penryn/QC, SoFIA 3GR, Wolfdale, Wolfdale Xeon, Yorkfield, and Yorkfield Xeon series. Over the top, the 8 Gen Intel Core i9-8950HK processor is optimized to overshoot the performance limits of portable devices.

Use HP, Lenovo or Dell?

Intel's chips are some of the only components in Apple's products that are designed by others.


Sensitive data protected by Intel's Software Guard Extensions could be open to a new side-channel attack.

However, there are microcodes updates that do protect against the first variation of Spectre and the more serious Meltdown flaw.

Today at a global event in Beijing, Intel unveiled the first ever Intel® Core™ i9 processor for laptops. In its inimitable way the Reg says that the 10 product families will be neglected by Intel fixers and patchers "in some cases because it's too tricky to remove the Spectre v2 class of vulnerabilities".

And offers patching tips from US CERT, which it failed to brief on the bugs.

Now, financial analyst Wasmi Mohan - who works at Merrill Lynch - has added further discussion to the rumours by claiming that Apple would be able to boost productivity by making its own chips.

Intel has warned that it nearly certainly won't be able to provide a fix for the second variant of the Spectre flaw for all but the latest of its desktop, laptop and server CPUs.
