      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: macb: destroy the phylink instance on the probe error path\n\nmacb_mii_init() creates a phylink instance on both of its success paths,\nbut the probe unwind frees the netdev without destroying it, so a failing\nmacb_alloc_tieoff() or register_netdev() leaks the instance.\n\nDestroy it at err_out_unregister_mdio, which is only reachable once\nmacb_mii_init() has succeeded, so bp->phylink is valid there."
