A fix is available — apply it.

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. sysfs: cannot create duplicate filename '/devices/virtual/mac80211_hwsim' Call Trace:
