Security readout for executives and security teams
This flaw can let someone within wireless proximity crash certain Cisco Catalyst switches when they are acting as wireless LAN controllers. The result is a denial-of-service outage, not data theft based on the provided sources. Exposure is limited to Catalyst 3650 and 3850 switches running IOS XE 16.1 through 16.3.3 in WLC mode. Organizations are likely exposed only where Catalyst 3650 or 3850 switches run IOS XE 16.1 through 16.3.3 and provide WLC functionality. Pure wired switching deployments or other platforms are not identified as affected in the supplied sources. Treat this as a targeted availability risk. It is not described as data compromise, but a successful attack can disrupt wireless services and restart affected switches. Prioritize branch, campus, or operational locations that depend on the affected switches for wireless connectivity. Mitigation focus: Check Cisco advisory guidance for fixed IOS XE releases or supported workarounds.; Inventory Catalyst 3650 and 3850 switches that operate as wireless LAN controllers.; Prioritize remediation for sites where wireless outage would affect operations or safety..
