On launching a TCP SYN flood against a device running the vulnerable versions of Android, the device becomes unresponsive and in extreme cases, crash. The large number of SYN packets sent to the device probably leads to kernel memory exhaustion due to the excess of Transmission Control Blocks created in response. A TCB is allocated for each SYN packet sent by the attacker and is of a length that varies according to the operating system. If the attacker keeps sending packets incessantly, this leads to the exhaustion of memory and causes the Android operating system to hang.
