Advisory ID: RHSA-2023:2162-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2023:2162
Issue date: 2023-05-09
CVE Names: CVE-2022-3165 CVE-2022-4172
=====================================================================
1. Summary:
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 Moderate. 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.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AppStream (v. 9) - aarch64, ppc64le, s390x, x86_64
3. 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.
The following packages have been upgraded to a later upstream version:
qemu-kvm (7.2.0). (BZ#2111769, BZ#2135806)
Security Fix(es):
* QEMU: VNC: integer underflow in vnc_client_cut_text_ext leads to CPU
exhaustion (CVE-2022-3165)
* QEMU: ACPI ERST: memory corruption issues in read_erst_record and
write_erst_record (CVE-2022-4172)
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.
Additional Changes:
For detailed information on changes in this release, see the Red Hat
Enterprise Linux 9.2 Release Notes linked from the References section.
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
all virtual machines have shut down, start them again for this update to
take effect.
