HighCVSS 7.5/10Last modified Jun 17, 2026

Description

A vulnerability in the IPv4 Software-Defined Access (SD-Access) fabric edge node feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause high CPU utilization and stop all traffic processing, resulting in a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of certain IPv4 packets. An attacker could exploit this vulnerability by sending certain IPv4 packets to an affected device. A successful exploit could allow the attacker to cause the device to exhaust CPU resources and stop processing traffic, resulting in a DoS condition.
