CVE-2022-50246

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> usb: typec: tcpci: fix of node refcount leak in tcpci_register_port()<br /> <br /> I got the following report while doing device(mt6370-tcpc) load<br /> test with CONFIG_OF_UNITTEST and CONFIG_OF_DYNAMIC enabled:<br /> <br /> OF: ERROR: memory leak, expected refcount 1 instead of 2,<br /> of_node_get()/of_node_put() unbalanced - destroy cset entry:<br /> attach overlay node /i2c/pmic@34/tcpc/connector<br /> <br /> The &amp;#39;fwnode&amp;#39; set in tcpci_parse_config() which is called<br /> in tcpci_register_port(), its node refcount is increased<br /> in device_get_named_child_node(). It needs be put while<br /> exiting, so call fwnode_handle_put() in the error path of<br /> tcpci_register_port() and in tcpci_unregister_port() to<br /> avoid leak.
