macb: destroy the phylink instance on the probe error path","description":"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.","state":0,"publishedAt":"2026-09-25T10:23:12.759+00:00","modifiedAt":"2026-10-19T09:11:39.063+00:00","affected":[{"ecosystem":"Vendor
