Summary

Dell OS10 Networking Switches running 10.5.2.x and above contain an Uncontrolled Resource Consumption (Denial of Service) vulnerability, when switches are configured with VLT and VRRP.

This is a high severity vulnerability as it allows an attacker to cause an outage of network. Dell recommends customers to upgrade at the earliest opportunity.
