Description
In the Linux kernel, the following vulnerability has been resolved: irqchip/ti-sci: Fix refcount leak in ti_sci_intr_irq_domain_probe of_irq_find_parent() returns a node pointer with refcount incremented, We should use of_node_put() on it when not needed anymore. Add missing of_node_put() to avoid refcount leak.

Executive Summary

This vulnerability is a reference count leak in the Linux kernel's irqchip/ti-sci component. Specifically, the function of_irq_find_parent() returns a node pointer with its reference count incremented, but the code did not properly decrement the reference count by calling of_node_put() 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. However, no direct security impact or exploit scenario is described.
