In the Linux kernel, the following vulnerability has been resolved:
mmc: vub300: fix return value check of mmc_add_host()
mmc_add_host() may return error, if we ignore its return value, the memory that allocated in mmc_alloc_host() 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 mmc_free_host(), besides, the timer added before mmc_add_host() needs be del.
And this patch fixes another missing call mmc_free_host() if usb_control_msg() fails.
