Description

In the Linux kernel, the following vulnerability has been resolved: clk: tegra20: Fix refcount leak in tegra20_clock_init of_find_matching_node() 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's tegra20 clock initialization code. The function of_find_matching_node() returns a node pointer with its reference count incremented, but the code did not call of_node_put() to decrement the reference count when the node was no longer needed. This missing call 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 as resources are not properly released.
