CVE-2022-20848: Cisco IOS XE Software for Embedded Wireless Controllers on Catalyst 9100 Series Access Points UDP Processing Denial of Service Vulnerability

First published: Fri Sep 30 2022(Updated: )

A vulnerability in the UDP processing functionality of Cisco IOS XE Software for Embedded Wireless Controllers on Catalyst 9100 Series Access Points could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. This vulnerability is due to the improper processing of UDP datagrams. An attacker could exploit this vulnerability by sending malicious UDP datagrams to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition.
