  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: cpsw_new: unregister devlink on port registration failure\n\ncpsw_probe() registers devlink before registering the CPSW ports.\n\nIf cpsw_register_ports() fails, the error path only unregisters the\nnotifiers and then releases the lower level resources. It does not undo\nthe successful cpsw_register_devlink() call, leaving the devlink instance\nand its parameters registered after probe has failed.\n\nAdd a devlink cleanup label for the path where devlink registration has\nalready succeeded, and use it when port registration fails.",
