A flaw was found in the vhost-vsock device of QEMU. In case of error an invalid element was not detached from the virtqueue before freeing its memory leading to memory leakage and other unexpected results. Affected QEMU versions 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 identifi
