CVE-2022-49415

Estado: AnalizadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

ipmi:ipmb: Fix refcount leak in ipmi_ipmb_probe

of_parse_phandle() 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.
