Cisco IOS 11.1CC through 12.2 with Cisco Express Forwarding (CEF) enabled includes portions of previous packets in the padding of a MAC level packet when the MAC packet's length is less than the IP level packet length.

Security readout for executives and security teams

This flaw can cause Cisco IOS routers using Cisco Express Forwarding to leak small fragments of earlier network traffic inside packet padding. The business risk is unintended disclosure of sensitive data passing through affected infrastructure, especially if legacy Cisco IOS devices remain in service. Exposure is most likely in legacy Cisco IOS environments running versions 11.1CC through 12.2 with Cisco Express Forwarding enabled. Modern supported images are not identified as affected in the supplied bundle. Treat this as a legacy infrastructure exposure review. Urgency is higher where old Cisco IOS routers still carry sensitive or regulated traffic. Absence from KEV lowers immediate exploitation urgency but does not remove disclosure risk. Mitigation focus: Inventory Cisco IOS routers and identify versions 11.1CC through 12.2.; Confirm whether Cisco Express Forwarding is enabled on identified devices.; Review Cisco's advisory for fixed releases or supported vendor remediation..
