Description OSIDB Bzimport 2025-02-26 03:01:39 UTC 
In the Linux kernel, the following vulnerability has been resolved:

irqchip/gic-v3: Fix refcount leak in gic_populate_ppi_partitions

of_find_node_by_phandle() 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.
