CVE-2023-52801 is a use-after-free vulnerability in the Linux kernel iommufd subsystem. When iopt_area_split() splits an iopt_area that has populated a domain and is linked into domains_itree, its page-node entries were not properly reinserted into domains_itree. The resulting inconsistent interval-tree state can lead to use-after-free access during subsequent domain or I/O page-table operations.
