   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)
