Description
In the Linux kernel, the following vulnerability has been resolved: cpufreq: zynq: Fix refcount leak in zynq_get_revision of_find_compatible_node() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. 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 cpufreq driver for Zynq devices. Specifically, the function of_find_compatible_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 done, causing a refcount leak. The fix adds the missing of_node_put() call to properly manage the reference count.


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, the exact impact depends on how the affected code is used in the system.
