Security readout for executives and security teams
This CVE describes a denial-of-service flaw in Cisco IOS 12.3 and 12.4 on Aironet access points. A remote attacker could make the radio interface input queue hang using specific IAPP packets, potentially disrupting wireless service. The available bundle does not provide CVSS, affected model details, or a confirmed fixed version. Exposure is most likely limited to legacy Cisco Aironet access points still running IOS 12.3 or 12.4. Organizations with retired, upgraded, or segmented wireless infrastructure are less likely to be affected, but the bundle does not identify specific Aironet models. Treat this as a legacy wireless availability risk. It is unlikely to require emergency action without vulnerable Aironet hardware, but business-critical sites should verify exposure because successful exploitation could disrupt wireless connectivity. Mitigation focus: Inventory Cisco Aironet access points and record IOS versions.; Check Cisco guidance for CSCtc12426 and applicable fixed releases.; Upgrade or replace affected IOS 12.3 or 12.4 access points where supported..
