CVE-2019-1834 affects Cisco Aironet Series Access Points, allowing an unauthenticated, adjacent attacker to cause a denial of service (DoS) on the AP if the connecting switch port has security configured. The vulnerability, rated Medium severity (CVSS 6.5), stems from the AP forwarding malformed wireless client packets outside the CAPWAP tunnel, triggering a switch port security violation. While a workaround exists and exploitation requires a specific switch configuration, there is no known active exploitation, public exploit code, or significant community discussion surrounding this CVE.
