Does this matter?
Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
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.
