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 info

A flaw was found in the way the stv06xx driver in the Linux kernel handled certain types of USB descriptors. This flaw allows an attacker with the ability to induce the error conditions to crash the system.
Statement: This issue is rated as having Low impact because of the preconditions needed to trigger the issue (physical access).
Mitigation: In order to mitigate this issue it is possible to prevent the affect
