Summary

CVE-2022-49719 is a vulnerability affecting the Linux kernel. Specifically, in the "irqchip/gic/realview" component, a refcount leak was identified in the "realview_gic_of_init" function. The issue arises because the node pointer returned by "of_find_matching_node_and_match()" is not properly handled when no longer needed. To mitigate this vulnerability, the missing call to "of_node_put()" has been added to prevent refcount leaks.
