Overview

CVE-2022-50482 is a medium-severity vulnerability. It was published on October 4, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

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

A splat from kmem_cache_destroy() was seen with a kernel prior to

commit ee2653bbe89d ("iommu/vt-d: Remove domain and devinfo mempool")

when there was a failure in init_dmars(), because the iommu_domain

cache still had objects. While the mempool code is now gone, there

still is a leak of the si_domain memory if init_dmars() fails. So

clean up si_domain in the init_dmars() error path.

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.
