Summary

In the Linux kernel, the following vulnerability has been resolved: usb: typec: wusb3801: fix fwnode refcount leak in wusb3801_probe() I got the following report while doing fault injection test: OF: ERROR: memory leak, expected refcount 1 instead of 4, of_node_get()/of_node_put() unbalanced - destroy cset entry: attach overlay node /i2c/tcpc@60/connector If wusb3801_hw_init() fails, fwnode_handle_put() needs be called to avoid refcount leak.
