In the Linux kernel, the following vulnerability has been resolved:
ax25: Fix netdev refcount issue
The dev_tracker is added to ax25_cb in ax25_bind(). When the
ax25 device is detaching, the dev_tracker of ax25_cb should be
deallocated in ax25_kill_by_device() instead of the dev_tracker
of ax25_dev. The log reported by ref_tracker is shown below:

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.
