A vulnerability in the packet processing functionality of Cisco access point (AP) software could allow an unauthenticated, adjacent attacker to exhaust resources on an affected device.&nbsp;<br><br> This vulnerability is due to insufficient management of resources when handling certain types of traffic. An attacker could exploit this vulnerability by sending a series of specific wireless packets to an affected device. A successful exploit could allow the attacker to consume resources on an affected device. A sustained attack could lead to the disruption of the Control and Provisioning of Wireless Access Points (CAPWAP) tunnel and intermittent loss of wireless client traffic.<br><br> Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.<br><br> This advisory is available at the following link:<br><a href="https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-dos-capwap-DDMCZS4m">https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-dos-capwap-DDMCZS4m</a><br><br> <br/>Security Impact Rating: Medium <br/>CVE: CVE-2023-20268
