Intel haswell cpus receive microcode in windows update against vulnerabilities

Some time ago, Microsoft started rolling out microcode updates on some generations of older processors. Generations of processors like Core, Pentium and Celeron from Intel have already received them through Windows Update. Now it is the turn of a new cumulative update, which in this case is released to computers with fourth generation Intel Core Haswell processor.

Intel Haswell CPUs receive microcode in Windows Update against vulnerabilities

This update is also released for low-power Celeron and Pentium variants based on Apollo Lake, Gemini Lake, Cherry View, and Valley View. This is the KB4497165 update that has been released.

Official update

For users with an Intel Haswell processor, all you have to do is wait and let Windows Update do its thing. So this is an automatic update for users in this case. This update improves security and protects against vulnerabilities. It does this in four main variants in this case, related to MDS vulnerabilities.

As they have said from Microsoft, these are the vulnerabilities CVE -2019-11091 (MDS Uncacheable Memory), CVE-2018-12126 (Microarchitectural Store Buffer Data Sampling), CVE-2018-12127 (Microarchitectural Load Port Data Sampling), and CVE- 2018-12130 (Microarchitectural Fill Buffer Data Sampling).

Therefore, if you have a computer that uses an Intel Haswell processor, then you will already have this update, or it will arrive shortly. It is unknown if there will be performance loss due to upgrade. Nothing has been said in this regard so far, but it may happen.
