In the Linux kernel, the following vulnerability has been resolved:
mmc: moxart: fix return value check of mmcaddhost()
mmcaddhost() may return error, if we ignore its return value, the memory that allocated in mmcallochost() will be leaked and it will lead a kernel crash because of deleting not added device in the remove path.
So fix this by checking the return value and goto error path which will call mmcfreehost().
