Intel issued security patches for infamous security bugs that issued by Google Project Zero and the update is only for Skylake processors to address Spectre vulnerability.
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. Later Intel said 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.
Now after a week, Intel released microcode updates to Skylake chips, and these updates are made available via OEM firmware updates.Intel said we expect to do the same for more platforms in the coming days.
Intel fixed the vulnerability only with Skylake, leaving Kaby Lake, Sandy Bridge, Ivy Bridge, Broadwell H, Haswell, Haswell Perf, Coffee Lake.
Crooks started trying to take advantage of the infamous bug Meltdown and Spectre which affects almost all the modern processors and pushes Smoke Loader malware as a patch.
