  "description": "In the Linux kernel, the following vulnerability has been resolved:  ubi: Fix possible null-ptr-deref in ubi_free_volume()  It willl cause null-ptr-deref in the following case:  uif_init()   ubi_add_volume()     cdev_add() -\u003E if it fails, call kill_volumes()     device_register()  kill_volumes() -\u003E if ubi_add_volume() fails call this function   ubi_free_volume()     cdev_del()     device_unregister() -\u003E trying to delete a not added device, \t\t\t   it causes null-ptr-deref  So in ubi_free_volume(), it delete devices whether they are added or not, it will causes null-ptr-deref.  Handle the error case whlie calling ubi_add_volume() to fix this problem. If add volume fails, set the corresponding vol to null, so it can not be accessed in kill_volumes() and release the resource in ubi_add_volume() error path.",
