The vulnerability exists because the affected software attempts to free the same area of memory twice. An attacker could exploit this vulnerability by sending a pong request to an affected device from a location on the network that causes the pong reply packet to egress both a FabricPath port and a non-FabricPath port. An exploit could allow the attacker to cause a dual or quad supervisor virtual port-channel (vPC) to reload. This vulnerability affects the following products when running Cisco NX-OS Software Release 7.2(1)D(1), 7.2(2)D1(1), or 7.2(2)D1(2) with both the Pong and FabricPath features enabled and the FabricPath port is actively monitored via a SPAN session: Cisco Nexus 7000 Series Switches and Cisco Nexus 7700 Series Switches.

Un atacante podr\u00eda explotar esta vulnerabilidad enviando una petici\u00f3n pong a un dispositivo afectado desde una ubicaci\u00f3n en la red que provoca que el paquete de respuesta pong salga tanto de un puerto FabricPath como de un puerto no FabricPath. Su explotaci\u00f3n podr\u00eda permitir que el atacante haga que se reinicie el vPC (Virtural port-channel) supervisor dual o quad.
