Upstream information
Description
In the Linux kernel, the following vulnerability has been resolved:driver core: fix resource leak in device_add()
When calling kobject_add() failed in device_add(), it will call
cleanup_glue_dir() to free resource. But in kobject_add(),
dev->kobj.parent has been set to NULL. This will cause resource leak.
The process is as follows:
device_add()
get_device_parent()
class_dir_create_and_add()
kobject_add() //kobject_get()
...
dev->kobj.parent = kobj;
...
kobject_add() //failed, but set dev->kobj.parent = NULL
...
glue_dir = get_glue_dir(dev) //glue_dir = NULL, and goto
//"Error" label
...
cleanup_glue_dir() //becaues glue_dir is NULL, not call
//kobject_put()
The preceding problem may cause insmod mac80211_hwsim.ko to failed.
