Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send specially manipulated packets, cause the module state to change to halt-mode and cause a denial of service condition on the target device.
