  "details": "In the Linux kernel, the following vulnerability has been resolved:  btrfs: fix double free in create_space_info_sub_group() error path  When kobject_init_and_add() fails, the call chain is:  create_space_info_sub_group() -\u003e btrfs_sysfs_add_space_info_type() -\u003e kobject_init_and_add() -\u003e failure -\u003e kobject_put(\u0026sub_group-\u003ekobj) -\u003e space_info_release() -\u003e kfree(sub_group)  Then control returns to create_space_info_sub_group(), where:  btrfs_sysfs_add_space_info_type() returns error -\u003e kfree(sub_group)  Thus, sub_group is freed twice.  Keep parent-\u003esub_group[index] = NULL for the failure path, but after btrfs_sysfs_add_space_info_type() has called kobject_put(), let the kobject release callback handle the cleanup.",
