Description OSIDB Bzimport 2025-02-26 03:20:49 UTC 
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.
