What is CVE-2022-45854?

The Zyxel NWA110AX firmware, prior to version 6.50(ABTG.0)C0, contains an implementation flaw that permits a local area network (LAN) attacker to initiate a temporary denial of service (DoS) attack. By sending specially crafted VLAN frames upon intercepting the MAC address of the affected access point, an adversary can disrupt the service, rendering the network inoperable. This vulnerability highlights the need for timely updates to firmware to safeguard against potential exploits.
