Description

The vulnerability allows an adjacent attacker to cause DoS condition on the target system.

The vulnerability exists in the default configuration due to insufficient validation of user-supplied input. An adjacent attacker can send specially crafted packets to cause the target Traffic Management Microkernel (TMM) to restart and traffic to disrupt.

Successful exploitation of the vulnerability results in denial of service.

Mitigation
The vulnerability is addressed in the following versions: 11.5.5, 11.6.2, 12.1.3, 13.1.0.
