Bluetooth: Fix leak of uninitialized data to userspace
struct hci_dev_list_req {
__u16 dev_num;
struct hci_dev_req dev_req[0]; /* hci_dev_req structures */
};
sizeof(struct hci_dev_list_req) == 4, so the two bytes immediately
following "dev_num" will never be initialized. When this structure
is copied to userspace, these uninitialized bytes are leaked.
Fix by using kzalloc() instead of kmalloc(). Found using kmemcheck.
