The following commit has been merged in the master branch: commit ae3cdc97dc10c7a3b31f297dab429bfb774c9ccb Author: Sven Eckelmann <sven(a)narfation.org> Date: Sun Aug 12 21:04:45 2018 +0200 batman-adv: Prevent duplicated tvlv handler The function batadv_tvlv_handler_register is responsible for adding new tvlv_handler to the handler_list. It first checks whether the entry already is in the list or not. If it is, then the creation of a new entry is aborted. But the lock for the list is only held when the list is really modified. This could lead to duplicated entries because another context could create an entry with the same key between the check and the list manipulation. The check and the manipulation of the list must therefore be in the same locked code section.

This is usually a lot more than the number of bytes which the template ELP packet requires. These extra padding bytes were not initialized and thus could contain data which were previously stored at the same location. It is therefore required to set it to some predefined or random values to avoid leaking private information from the system transmitting these kind of packets.
