January 5, 2018
An update that fixes one vulnerability is now available.
Description
This update for ucode-intel fixes the following issues:
The CPU microcode for Haswell-X, Skylake-X and Broadwell-X chipsets was
updated to report both branch prediction control via CPUID flag and
ability to control branch prediction via an MSR register.
This update is part of a mitigation for a branch predictor based
information disclosure attack, and needs additional code in the Linux
Kernel to be active (bsc#1068032 CVE-2017-5715)
