Red Hat Security Advisory

Synopsis: Important: linux-firmware security update
Advisory ID: RHSA-2018:0094-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2018:0094
Issue date: 2018-01-16
=====================================================================

1. Summary:

An update for linux-firmware is now available for Red Hat Enterprise Linux
7, Red Hat Enterprise Linux 7.2 Advanced Update Support, Red Hat Enterprise
Linux 7.2 Telco Extended Update Support, Red Hat Enterprise Linux 7.2
Update Services for SAP Solutions, and Red Hat Enterprise Linux 7.3

Red Hat Enterprise Linux for ARM and IBM Power LE (POWER9) Server (v. 7) – noarch

3. Description:

The linux-firmware packages contain all of the firmware files that are
required by various devices to operate.

This update supersedes microcode provided by Red Hat with the CVE-2017-5715
(“Spectre”) CPU branch injection vulnerability mitigation. (Historically,
Red Hat has provided updated microcode, developed by our microprocessor
partners, as a customer convenience.) Further testing has uncovered
problems with the microcode provided along with the “Spectre” mitigation
that could lead to system instabilities. As a result, Red Hat is providing
an microcode update that reverts to the last known good microcode version
dated before 03 January 2018. Red Hat strongly recommends that customers
contact their hardware provider for the latest microcode updates.

IMPORTANT: Customers using Intel Skylake-, Broadwell-, and Haswell-based
platforms must obtain and install updated microcode from their hardware
vendor immediately. The “Spectre” mitigation requires both an updated
kernel from Red Hat and updated microcode from your hardware vendor.
