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.

An issue was discovered in the Linux kernel before 4.19.9. The USB subsystem mishandles size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c.
A flaw was discovered in the Linux kernel's USB subsystem in the __usb_get_extra_descriptor() function in the drivers/usb/core/usb.c which mishandles a size check during the reading of an extra descriptor data. By using a specially crafted USB device which sends a forged extra descriptor, an unprivileged user with physical access to the system can potentially cause a privilege escalation or trigger a system crash or lock up and thus to cause a denial of service (DoS).
