The remote Red Hat host is missing a security update for qemu-kvm.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2023:5094 advisory.

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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
