CVE (CAN) ID: CVE-2012-6396
 
Cisco NX-OS is a data center-level operating system that represents a modular design, always-on and maintainability.
 
A denial of service vulnerability exists when Cisco Nexus 7000 series switches running NX-OS do not properly handle some line-card replacement events. Remote authenticated attackers construct a configuration to make the affected module reference interfaces that do not exist on the new card, resulting in a large amount of memory and system resource consumption of the affected device and DOS.
