MediumCVSS 5.5/10Last modified Jun 17, 2026

Description

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

powerpc/iommu: Add missing of_node_put in iommu_init_early_dart

The device_node pointer is returned by of_find_compatible_node with refcount incremented. We should use of_node_put() to avoid the refcount leak.
