  "details": "In the Linux kernel, the following vulnerability has been resolved:  btrfs: fix double free in create_space_info() error path  When kobject_init_and_add() fails, the call chain is:  create_space_info() -\u003e btrfs_sysfs_add_space_info_type() -\u003e kobject_init_and_add() -\u003e failure -\u003e kobject_put(\u0026space_info-\u003ekobj) -\u003e space_info_release() -\u003e kfree(space_info)  Then control returns to create_space_info():  btrfs_sysfs_add_space_info_type() returns error -\u003e goto out_free -\u003e kfree(space_info)  This causes a double free.  Keep the direct kfree(space_info) for the earlier failure path, but after btrfs_sysfs_add_space_info_type() has called kobject_put(), let the kobject release callback handle the cleanup.",
