Date: Tue, 15 Dec 2009 17:55:06 +0000 [thread overview]
Message-ID: <200912151755.06796.strakh@ispras.ru> (raw)
KERNEL_VERSION: 2.6.32
SUBJECT: null dereference after check
DESCRIBE:
In driver ./drivers/isdn/icn/icn.c in function icn_addcard:
1. If in line 1580 card2 = NULL then we goto line 1581
2. In line 1581 we have null dereference because printk called with card2-
>interface.id in third parameter.
1580 if (!(card2 = icn_initcard(port, id2))) {
1581 printk(KERN_INFO
1582 "icn: (%s) half ICN-4B, port 0x%x added\n",
1583 card2->interface.id, port);
1584 return 0;
1585 }
