 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:firmware: arm_scmi: Balance device refcount when destroying devicesUsing device_find_child() to lookup the proper SCMI device to destroycauses an unbalance in device refcount, since device_find_child() calls animplicit get_device(): this, in turns, inhibits the call of the providedrelease methods upon devices destruction.As a consequence, one of the structures that is not freed properly upondestruction is the internal struct device_private dev->p populated by thedrivers subsystem core.KMemleak detects this situation since loading/unloding some SCMI drivercauses related devices to be created/destroyed without calling anydevice_release method.unreferenced object 0xffff00000f583800 (size 512):  comm  insmod , pid 227, jiffies 4294912190  hex dump (first 32 bytes):    00 00 00 00 ad 4e ad de ff ff ff ff 00 00 00 00  .....N..........    ff ff ff ff ff ff ff ff 60 36 1d 8a 00 80 ff ff  ........`6......  backtrace (crc 114e2eed):    kmemleak_alloc+0xbc/0xd8    __kmalloc_cache_noprof+0x2dc/0x398    device_add+0x954/0x12d0    device_register+0x28/0x40    __scmi_device_create.part.0+0x1bc/0x380    scmi_device_create+0x2d0/0x390    scmi_create_protocol_devices+0x74/0xf8    scmi_device_request_notifier+0x1f8/0x2a8    notifier_call_chain+0x110/0x3b0    blocking_notifier_call_chain+0x70/0xb0    scmi_driver_register+0x350/0x7f0    0xffff80000a3b3038    do_one_initcall+0x12c/0x730    do_init_module+0x1dc/0x640    load_module+0x4b20/0x5b70    init_module_from_file+0xec/0x158$ ./scripts/faddr2line ./vmlinux device_add+0x954/0x12d0device_add+0x954/0x12d0:kmalloc_noprof at include/linux/slab.h:901(inlined by) kzalloc_noprof at include/linux/slab.h:1037(inlined by) device_private_init at drivers/base/core.c:3510(inlined by) device_add at drivers/base/core.c:3561Balance device refcount by issuing a put_device() on devices found viadevice_find_child().
