Description OSIDB Bzimport 2025-02-26 03:19:09 UTC 
In the Linux kernel, the following vulnerability has been resolved:

irqchip/gic/realview: Fix refcount leak in realview_gic_of_init

of_find_matching_node_and_match() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
