Since adev is embedded in\nstruct mana_adev, the subsequent fall-through to init_fail and access\nto adev->id may result in a use-after-free.\n\nFix this by saving the allocated auxiliary device id in a local\nvariable before calling auxiliary_device_add(), and use that saved id\nin the cleanup path after auxiliary_device_uninit().","state":0,"publishedAt":"2026-05-01T14:15:48.837+00:00","modifiedAt":"2026-10-19T19:06:11.769+00:00","affected":[{"ecosystem":"Vendor
