Description OSIDB Bzimport 2025-06-18 12:01:43 UTC
In the Linux kernel, the following vulnerability has been resolved:

powerpc/xive: Fix refcount leak in xive_get_max_prio

of_find_node_by_path() returns a node pointer with
refcount incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
