In the Linux kernel, the following vulnerability has been resolved:

mcb: mcb-parse: fix error handing in chameleon_parse_gdd()

If mcb_device_register() returns error in chameleon_parse_gdd(), the refcount
of bus and device name are leaked. Fix this by calling put_device() to give up
the reference, so they can be released in mcb_release_dev() and kobject_cleanup().
