  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ntg3: clean up PHYLIB resources on probe failure\n\ntg3_get_invariants() can register an MDIO bus and connect a PHY for\nUSE_PHYLIB devices. If tg3_init_one() later fails, its common error path\nreleases the mappings and netdev without undoing those PHYLIB resources.\n\nDisconnect the PHY and unregister the MDIO bus before the remaining\nteardown. Guard PHY cleanup with USE_PHYLIB to match tg3_phy_init(), and\ncall tg3_mdio_fini() unconditionally to match tg3_mdio_init(). The existing\nIS_CONNECTED and MDIOBUS_INITED flags make both helpers safe when\ninitialization only completed partially.\n\nThis issue was identified during our ongoing static-analysis research while\nreviewing kernel code.",
