[PATCH 0/2] bluetooth: fix NULL-pointer dereferences

[Johan Hovold]

Hi, 

These patches fixes two races in hci_ldisc and hci_core which can lead to
NULL-pointer dereferences.

The first one is 100% reproducible on 3.2 as well as 3.3-rc6 and needs to be
backported to all stable kernels as the offending code has been around for
quite some time.

The second one is 100% reproducible on 3.3-rc6 but I haven't seen it on 3.2 or
earlier, but as far as I can see it could be possibly to trigger it at least on
3.0 and later.


Thanks,
Johan
