Subject: [PATCH 0/2] Bluetooth: fix hci-uart crashes
Date: Wed, 29 Mar 2017 18:15:26 +0200 [thread overview]
Message-ID: <20170329161528.17843-1-johan@kernel.org> (raw)
Not every tty has a class device and this could be used to trigger
NULL-pointer dereferences in two hci-uart drivers that lacked the
required sanity checks.
