Topic

Updated linux-firmware packages that fix one bug are now available for Red Hat Enterprise Linux 7.2 Advanced Update Support.

Description

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

This update fixes the following bug:

  • A previous update to the linux-firmware packages that added new capabilities to enhance mitigation of CVE-2017-5715 (the Spectre variant 2 vulnerability) introduced a regression when it inadvertently removed support for AMD CPUID 0x00610f01. As a consequence, the kernel would be unable to update the microcode loaded by BIOS or UEFI if it was outdated because the loaded microcode version is dependent on the BIOS or UEFI version in use. This update restores microcode support for the mentioned CPU family, and the microcode can be correctly updated again. (BZ#1585936)

Users of linux-firmware are advised to upgrade to these updated packages, which fix this bug.

Solution

Before applying this update, make sure all previously released errata
