What is CVE-2023-20176?

A vulnerability in the networking component of Cisco access point software allows unauthenticated remote attackers to cause temporary service disruption. By connecting to the access point as a wireless client and transmitting excessive traffic for a prolonged duration, the attacker can exploit this weakness. This leads to the tearing down and resetting of the Datagram TLS (DTLS) session, ultimately resulting in a denial of service condition.
