Severity ?
7.4 (High) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H
Summary
A vulnerability in the handling of specific packets that are punted from a line card to a route processor in Cisco IOS XR Software Release 7.9.2 could allow an unauthenticated, adjacent attacker to cause control plane traffic to stop working on multiple Cisco IOS XR platforms.  This vulnerability is due to incorrect handling of packets that are punted to the route processor. An attacker could exploit this vulnerability by sending traffic, which must be handled by the Linux stack on the route processor, to an affected device. A successful exploit could allow the attacker to cause control plane traffic to stop working, resulting in a denial of service (DoS) condition.

Esta vulnerabilidad se debe a la gestión incorrecta de los paquetes que se envían al procesador de rutas. Un atacante podría explotar esta vulnerabilidad enviando tráfico, que debe ser gestionado por la pila de Linux en el procesador de rutas, a un dispositivo afectado. Una explotación exitosa podría permitir al atacante provocar la interrupción del tráfico del plano de control, lo que resultaría en una denegación de servicio (DoS).",
