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.

CVE-2018-19665 Qemu: bt: Integer overflow in Bluetooth routines allows memory corruption
An integer overflow resulting in memory corruption issue was found in various Bluetooth functions. It could occur in routines wherein 'len' parameter is a 'signed int' which subsequently converts to an unsigned integer resulting in memcpy() copying large amounts of memory.
A user inside guest could use this flaw to crash the Qemu process resulting in DoS.
