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.

In the Linux kernel before 5.6.1, drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink camera USB driver) mishandles invalid descriptors, aka CID-a246b4d54770.
A NULL pointer dereference flaw was found in the Xirlink camera USB driver 'xirlink-cit' in the Linux kernel. The driver mishandles invalid descriptors leading to a denial-of-service (DoS). This could allow a local attacker with user privilege to crash the system or leak kernel internal information.
Mitigation: Mitigation for this issue is to skip loading the affected module 'xirlink-cit' onto the system till we have a fix available, this can be done by a blacklist mechanism, this will ensure the driver is not loaded at the boot time.
