Details

In reassembleanddispatch of packet_fragmenter.cc, there is a possible way to inject packets into an encrypted Bluetooth connection due to improper input validation. This could lead to remote escalation of privilege between two Bluetooth devices by a proximal attacker, with no additional execution privileges needed. User interaction is not needed for exploitation.
