Intel initially released patches for Spectre and Meltdown on Jan. 15 which covers 90% of the modern CPUs, but it results in higher system reboots after applying firmware updates. Most affected ones are the systems running Intel Broadwell and Haswell CPUs for both client and data center.
Intel told now they have identified the root cause of the reboot issue that affected Broadwell and Haswell CPUs and they are preparing a solution to address the issue and asks to hold off applying patches for Spectre and Meltdown.
Over the weekend, we began rolling out an early version of the updated solution to industry partners for testing, and we will make a final release available once that testing has been completed.

Intel Statement – Patches for Spectre and Meltdown
Intel says We recommend that OEMs, cloud service providers, system manufacturers, software vendors and end users stop deployment of current versions, as they may introduce higher than expected reboots and other unpredictable system behavior. We also ask that our industry partners focus efforts on testing early versions of the updated solution for Broadwell and Haswell we started rolling out this weekend. so we can accelerate its release. We expect to share more details on timing later this week. For those concerned about system stability, while we finalize the updated solutions, we are also working with our OEM partners on the option to utilize a previous version of microcode that does not display these issues but removes the Variant 2 (Spectre) mitigations. This would be delivered via a BIOS update, and would not impact mitigations for Variant 1 (Spectre) and Variant 3 (Meltdown).
CVE-2017-5753 and CVE-2017-5715 are the references to Spectre, CVE-2017-5754 is for Meltdown.Crooks trying to take advantage of the infamous Meltdown and Spectre bug and pushing malware with fake patches.
