In some special cases, an authenticated attacker can exploit this vulnerability because the software processes data improperly. Successful exploitation may lead to information leakage.

CloudEngine 12800 has a DoS vulnerability. An attacker of a neighboring device sends a large number of specific packets. As a result, a memory leak occurs after the device uses the specific packet. As a result, the attacker can exploit this vulnerability to cause DoS attacks on the target device.
