CVE-2022-26354 [MEDIUM] QEMU vulnerabilities
Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
Alexander Bulekov discovered that QEMU incorrectly handled floppy disk
emulation. A privileged attacker inside the guest could use this issue to
cause QEMU to crash, resulting in a denial of service, or possibly leak
sensitive information. (CVE-2021-3507)
It was discovered that QEMU incorrectly handled NVME controller emulation.
An attacker inside the guest could use this issue to cause QEMU to crash,
resulting in a denial of service, or possibly execute arbitrary code. This
issue only affected Ubuntu 22.04 LTS. (CVE-2021-3929)
It was discovered that QEMU incorrectly handled QXL display device
emulation. A privileged attacker inside the guest could use this issue to
cause QEMU to crash, resulting in a deni

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.
