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.

AI Powered Q&A
Can you explain this vulnerability to me?
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.
How can this vulnerability impact me? :
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.
