Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
Ziming Zhang and VictorV discovered that the QEMU SLiRP networking
implementation incorrectly handled replying to certain ICMP echo requests.
An attacker inside a guest could possibly use this issue to leak host
memory to obtain sensitive information. This issue only affected Ubuntu
18.04 LTS. (CVE-2020-10756)
Eric Blake and Xueqiang Wei discovered that the QEMU NDB implementation
incorrectly handled certain requests. A remote attacker could possibly use
this issue to cause QEMU to crash, resulting in a denial of service. This
issue only affected Ubuntu 20.04 LTS. (CVE-2020-10761)
Ziming Zhang discovered that the QEMU SM501 graphics driver incorrectly
handled certain operations. An attacker inside a guest

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 impact to additional products is identified, we will update the CVE to reflect this.

QEMU: division by zero in oss_write() in audio/ossaudio.c
oss_write in audio/ossaudio.c in QEMU before 5.0.0 mishandles a buffer position.
A divide-by-zero flaw was found in the Open Sound System (OSS) implementation of the QEMU emulator. A guest user or process may use this flaw to crash the QEMU process on the host, resulting in a denial of service.
Statement: Open Sound System (OSS) is deprecated in favor of ALSA and disabled in Red Hat products. This flaw did not affect the following versions of QEMU as they did not include support for OSS:
* `qemu-kvm-ma` as shipped with Red Hat Enterprise Linux 7.
* `qemu-kvm-rhev` as shipped with Red Hat Virtualization and Red Hat OpenStack.
* `qemu-kvm` as shipped with Red Hat Enterprise Linux 6, 7 and 8.
* `virt:8.2/qemu-kvm` as shipped with RH
