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->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.
