RHSA-2023:5094 - Important: qemu-kvm security and bug fix update

Synopsis

Important: qemu-kvm security and bug fix update

Type/Severity

Security Advisory Important

Topic

An update for qemu-kvm is now available for Red Hat Enterprise Linux 9.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm packages provide the user-space component for running virtual machines that use KVM.

Security Fix(es):

• QEMU: VNC: improper I/O watch removal in TLS handshake can lead to remote unauthenticated denial of service (CVE-2023-3354)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

• [qemu-kvm] rhel guest failed boot with multi disks on error Failed to start udev Wait for Complete Device Initialization (BZ#2211923)

• [rhel9.2] hotplug/hotunplug mlx vdpa device to the occupied addr port, then qemu core dump occurs after shutdown guest (BZ#2227721)

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect.
