high Nessus Plugin ID 162653

Synopsis

The remote Red Hat host is missing one or more security updates for qemu-kvm.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:5263 advisory.

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: virtio-net: map leaking on error during receive (CVE-2022-26353)

* QEMU: vhost-vsock: missing virtqueue detach on error can lead to memory leak (CVE-2022-26354)

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):

* RHEL 9.0 guest with vsock device migration failed from RHEL 9.0 > RHEL 8.6 (BZ#2071102)

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

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

Solution

Update the RHEL qemu-kvm package based on the guidance in RHSA-2022:5263.
