Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the input_l2cap_frame_flow_channel() function in ble-l2cap.c. When fragments are reassembled in the BLE-L2CAP module they are stored in a packet buffer of a configurable size, but there is no check to verify that the packet buffer is large enough to hold the reassembled packet. An out-of-bounds write of up to 1152 bytes is possible.
