Summary

CVE-2022-49718 is a vulnerability affecting the Linux kernel where a refcount leak issue was identified in the 'irqchip/apple-aic' component. This vulnerability arises due to the failure to use 'of_node_put()' to decrease the reference count of nodes obtained using 'of_get_child_by_name()'. The consequence of this oversight is a potential refcount leak, which may have security implications if it leads to resource exhaustion or memory corruption. The issue has been rectified in recent kernel releases.
