You may recall that at the beginning of this year very serious safety deficiencies were uncovered in Intel’s 6th generation and in the upstream processors. The real threat of outages was not fully identified, but the potential threat to your data was there.
The big giants took their time, but finally, the solution came with a new Windows 10 update released, providing Intel users with multiple patches to prevent at least two types of Spectre infiltrations and some problems with the L1 Terminal Fault, also known as Foreshadow.
On the official update page, Microsoft said that the patch fixes the following problems:
Spectre Variant 3a (CVE-2018-3640: “Rogue System Register Read (RSRE)”)
Spectre variant 4 (CVE-2018-3639: “Speculative Store Bypass (SSB)”)
L1TF (CVE-2018-3620, CVE-2018-3646: “L1 Terminal error”)
These agreements were made in a joint work between Intel and Microsoft. The update is part of the October update, version 1809, which has caused Microsoft so many problems.
