  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnvdimm/bus: Fix potential use after free in asynchronous initialization\n\nDingisoul with KASAN reports a use after free if device_add() fails in\nnd_async_device_register().\n\nCommit b6eae0f61db2 (\"libnvdimm: Hold reference on parent while\nscheduling async init\") correctly added a reference on the parent device\nto be held until asynchronous initialization was complete.  However, if\ndevice_add() results in an allocation failure the ref count of the\ndevice drops to 0 prior to the parent pointer being accessed.  Thus\nresulting in use after free.\n\nThe bug bot AI correctly identified the fix.  Save a reference to the\nparent pointer to be used to drop the parent reference regardless of the\noutcome of device_add().",
