CVE-2022-49609
Linux Kernel Power Reset Arm Versatile Refcount Leak
Description
In the Linux kernel, the following vulnerability has been resolved: power/reset: arm-versatile: Fix refcount leak in versatile_reboot_probe of_find_matching_node_and_match() 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.
