RHEA-2014:1236 - Product Enhancement Advisory

Topic

Updated microcode_ctl packages that add one enhancement are now available for
Red Hat Enterprise Linux 5.

Description

The microcode_ctl packages provide utility code and microcode data to assist the
kernel in updating the CPU microcode at system boot time. This microcode
supports all current x86-based, Intel 64-based, and AMD64-based CPU models. It
takes advantage of the mechanism built-in to Linux that allows microcode to be
updated after system boot. When loaded, the updated microcode corrects the
behavior of various processors, as described in processor specification updates
issued by Intel and AMD for those processors.

This update adds the following enhancement:

• With this update, the Intel CPU microcode has been updated to version

20140430. (BZ#1064359)

Users of microcode_ctl are advised to upgrade to these updated packages, which
add this enhancement. Note that a system reboot is necessary for this update to
take effect.
