Subject: [char-misc-next 0/3] mei: bus: null derefence in rx
Date: Thu, 29 Oct 2020 11:54:41 +0200 [thread overview]
Message-ID: <20201029095444.957924-1-tomas.winkler@intel.com> (raw)
Fix race in receive callback for drivers on me client
bus, that results in null dereferencing and improve
the error handling.
The first patch 'mei: protect mei_cl_mtu from null dereference'
itself is sufficient to prevent the failure and is intended
for stable.
Alexander Usyskin (3):
mei: protect mei_cl_mtu from null dereference
mei: bus: do not start a read for disconnected clients
mei: bus: deinitialize callback functions on init failure
