Summary

A vulnerability in Cisco Catalyst 6000, 5000, and 4000 switches allows remote attackers to trigger a denial of service condition by connecting to the SSH service using a non-SSH client. This action leads to a protocol mismatch, causing the device to become unresponsive to legitimate SSH requests, thereby affecting network operations and availability.
