In the Linux kernel, the following vulnerability has been resolved: usb: typec: wusb3801: fix fwnode refcount leak in wusb3801probe() I got the following report while doing fault injection test: OF: ERROR: memory leak, expected refcount 1 instead of 4, ofnodeget()/ofnodeput() unbalanced - destroy cset entry: attach overlay node /i2c/tcpc@60/connector If wusb3801hwinit() fails, fwnodehandle_put() needs be called to avoid refcount leak.
