Description OSIDB Bzimport 2025-02-26 03:07:27 UTC 
In the Linux kernel, the following vulnerability has been resolved:

powerpc/xive: Fix refcount leak in xive_spapr_init

of_find_compatible_node() 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.
