Wenwen Wang cbb88db76a ALSA: usx2y: fix a double free bug ... In usX2Y_In04_init(), a new urb is firstly created through usb_alloc_urb() and saved to 'usX2Y->In04urb'. Then, a buffer is allocated through kmalloc() and saved to 'usX2Y->In04Buf'. If the allocation of the buffer fails, the error code ENOMEM is returned after usb_free_urb(), which frees the created urb. However, the urb is actually freed at card->private_free callback, i.e., snd_usX2Y_card_private_free(). So the free operation here leads to a double free bug. To fix the above issue, simply remove usb_free_urb(). Signed-off-by: Wenwen Wang <wang6495@umn.edu> Signed-off-by: Takashi Iwai <tiwai@suse.de>		2019-04-29 19:56:41 +02:00
