iommufd: Fix missing update of domains_itree after splitting iopt_area
Noroxi assessment
Priority: Monitor (action score 35/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.59% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Linux Linux 836db2e7e4565d8218923b3552304a1637e2f28d, e7250ab7ca4998fe026f2149805b03e09dc32498, fcb32111f01ddf3cbd04644cde1773428e31de6a.
Low priority for now. Upgrade to Linux Linux 836db2e7e4565d8218923b3552304a1637e2f28d, e7250ab7ca4998fe026f2149805b03e09dc32498, fcb32111f01ddf3cbd04644cde1773428e31de6a or later.

Primary sources: NVD · CVE.org · FIRST EPSS
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.
