USN-6567-1 fixed vulnerabilities QEMU. The fix for CVE-2023-2861 was too
restrictive and introduced a behaviour change leading to a regression in
certain environments. This update fixes the problem.
Original advisory details:
Gaoning Pan and Xingwei Li discovered that QEMU incorrectly handled the
USB xHCI controller device. A privileged guest attacker could possibly use
this issue to cause QEMU to crash, leading to a denial of service. This
issue only affected Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2020-14394)
It was discovered that QEMU incorrectly handled the TCG Accelerator. A
local attacker could use this issue to cause QEMU to crash, leading to a

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.
