{"schema":"threatline.record/2","record":{"id":"CVE-2026-97973","aliases":[],"summary":"net: macb: destroy the phylink instance on the probe error path","details":"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.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
