Descriptions
In the Linux kernel, the following vulnerability has been resolved:
iommufd: Fix missing update of domains_itree after splitting iopt_area
In iopt_area_split(), if the original iopt_area has filled a domain and is
linked to domains_itree, pages_nodes have to be properly
reinserted. Otherwise the domains_itree becomes corrupted and we will UAF.
