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)
4. 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
