Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> vdpasim: fix memory leak when freeing IOTLBs<br /> <br /> After commit bda324fd037a ("vdpasim: control virtqueue support"),<br /> vdpasim-&gt;iommu became an array of IOTLB, so we should clean the<br /> mappings of each free one by one instead of just deleting the ranges<br /> in the first IOTLB which may leak maps.
