Description
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.

Executive Summary

This vulnerability is a reference count leak in the Linux kernel component related to the Xilinx VIPP media driver. Specifically, the function of_get_child_by_name() returns a node pointer with its reference count incremented, but the code did not properly release this reference using of_node_put() when it was no longer needed. This missing release causes a reference count leak.

Impact Analysis

The reference count leak can lead to resource leaks in the kernel, potentially causing increased memory usage or instability over time in systems using the affected Xilinx VIPP driver. This could degrade system performance or reliability.
