Description OSIDB Bzimport 2025-09-15 15:10:18 UTC 
In the Linux kernel, the following vulnerability has been resolved:

media: xilinx: vipp: Fix refcount leak in xvip_graph_dma_init

of_get_child_by_name() 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.
