mISDN: prevent possible NULL pointer dereference A return value of the bchannel_get_rxbuf() function is compared with the positive ENOMEM value instead of the negative -ENOMEM value to detect a memory allocation problem. Thus, after a possible memory allocation failure the bc->bch.rx_skb will be NULL which will lead to a NULL pointer dereference.
