Description
In the Linux kernel, the following vulnerability has been resolved: irqchip/irq-mvebu-gicp: Fix refcount leak in mvebu_gicp_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.

Can you explain this vulnerability to me?

This vulnerability is a reference count leak in the Linux kernel's irqchip/irq-mvebu-gicp component. Specifically, the function of_irq_find_parent() returns a node pointer with its reference count incremented, but the code was missing a call to of_node_put() to decrement the reference count when the node is 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. However, no direct exploit or severe impact such as code execution or data corruption is described.
