    Added Description 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.
