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.
