Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
