RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version:	libvirt-3.2.0-14.el7_4.8	Doc Type:	Bug Fix
Doc Text:	After applying all security patches for CVE-2017-5715 libvirt is supposed to report the host CPU as a model with "-IBRS" suffix (such as Westmere-IBRS). However, on some hosts the original model (without "-IBRS" suffix, such as Westmere) was reported by libvirt. This didn't have any effect on the actual availability of the security measures to virtual machines started on the host, but the incorrect CPU model could falsely indicate that the host was not secured yet. This update fixes the issue and the correct CPU model with "-IBRS" suffix should be reported on all updated hosts.	Story Points:	---
