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

mcb: fix a double free bug in chameleon_parse_gdd()

In chameleon_parse_gdd(), if mcb_device_register() fails, 'mdev' would be released in mcb_device_register() via put_device(). Thus, goto 'err' label and free 'mdev' again causes a double free. Just return if mcb_device_register() fails.
