  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: macb: put the \u0022mdio\u0022 child node reference on success  macb_mii_init() holds the reference returned by of_get_child_by_name() for macb_mdiobus_register() and drops it only on the error paths, so every successful probe leaks a node reference. On a CM5, overlay removal after four bind cycles reports    OF: ERROR: memory leak, expected refcount 1 instead of 5  Drop the reference after registration, where __mdiobus_register() has already taken its own for the lifetime of the bus.",
