Description
In the Linux kernel, the following vulnerability has been resolved: clk: tegra: Fix refcount leak in tegra210_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 Tegra clock initialization code. Specifically, 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 in systems using the affected Tegra clock code.

Mitigation Strategies

To mitigate this vulnerability, update the Linux kernel to a version that includes the fix for the refcount leak in tegra210_clock_init, where the missing of_node_put() call has been added to prevent the leak.
