CVE-2022-0897 [MEDIUM] libvirt vulnerabilities
Title: libvirt vulnerabilities
Summary: Several security issues were fixed in libvirt.
It was discovered that libvirt incorrectly handled the nwfilter driver. A
local attacker could possibly use this issue to cause libvirt to crash,
resulting in a denial of service. This issue only affected Ubuntu 22.04
LTS. (CVE-2022-0897)
It was discovered that libvirt incorrectly handled queries for the SR-IOV
PCI device capabilities. A local attacker could possibly use this issue to
cause libvirt to consume resources, leading to a denial of service.
(CVE-2023-2700)
Instructions: After a standard system update you need to reboot your computer to make all
the necessary changes.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If imp
