Intel Will Not Patch Spectre And Meltdown In Some Intel Chips

Intel Z300 Series, Intel Chips Spectre And Meltdown

Intel has been facing a lot of trouble since the Spectre and Meltdown security flaws were made public earlier this year and Intel has been trying to patch these security flaws in its chips but turns out these exploits won’t be patched out in some Intel chips.

According to Intel, it won’t be patching out Spectre and Meltdown exploits in some of its chips. Intel has stopped the microcode production for a total of 10 product families covering more than 200 processor models as you can see in the image below.

After a comprehensive investigation of the microarchitectures and microcode capabilities for these products, Intel has determined to not release microcode updates for these products for one or more reasons

The reason why Intel won’t be patching the Spectre and meltdown exploits in specific Intel chips is that of three reasons which are as follows.

• Micro-architectural characteristics that preclude a practical implementation of features mitigating Variant 2 (CVE-2017-5715)
• Limited Commercially Available System Software support
• Based on customer inputs, most of these products are implemented as “closed systems” and therefore are expected to have a lower likelihood of exposure to these vulnerabilities.

In related news, Intel has announced a slew of Coffee Lake Mobile CPUs with Intel Core i9 8950HK leading the H-Series. The Intel Core i9-8950HK has a base clock speed of 2.9GHz and the boost clock is 4.6GHz.

However, the boost clock for Intel Core i9-8950HK can go up to 4.8GHz thanks to Thermal Velocity Boost or TVB but, to reach this level of boost clock a certain criteria is to be met.

Intel Coffee Lake desktop CPUs along with mobile CPUs, all of them, will be using Intel 300 series chipset platform. The following are the CPU with which Intel is expanding its Desktop CPU range.

What do you think of some Intel chips not being patched for Spectre and meltdown exploits? Let us know i the comments.
