Summary
iommu/vt-d: Clean up si_domain in the init_dmars() error path
Details

In the Linux kernel, the following vulnerability has been resolved:

iommu/vt-d: Clean up sidomain in the initdmars() error path

A splat from kmemcachedestroy() was seen with a kernel prior to commit ee2653bbe89d ("iommu/vt-d: Remove domain and devinfo mempool") when there was a failure in initdmars(), because the iommudomain cache still had objects. While the mempool code is now gone, there still is a leak of the sidomain memory if initdmars() fails. So clean up sidomain in the initdmars() error path.
