Security readout for executives and security teams
This issue affects Cisco IOS XR on CRS-3 carrier routers. A remote attacker could send specially crafted IPv6 traffic that causes a network processor scan and line-card reload, creating a denial of service. The business risk is outage or degraded routing on affected carrier-grade infrastructure, not data theft. Exposure appears limited to CRS-3 systems running Cisco IOS XR 4.0.1 through 4.2.0 where IPv6 traffic can reach affected forwarding paths. Organizations without CRS-3, without these IOS XR versions, or without reachable IPv6 packet processing are less likely exposed based on the supplied evidence. Prioritize if the organization operates CRS-3 routers in production, especially in carrier, backbone, or high-availability environments. The available evidence supports availability risk to routing infrastructure, but does not show data compromise or confirmed active exploitation. Mitigation focus: Identify CRS-3 routers running Cisco IOS XR 4.0.1 through 4.2.0.; Consult Cisco advisory cisco-sa-20150611-iosxr for fixed software and official workarounds.; Prioritize remediation for internet-facing or transit-facing IPv6 routing infrastructure..
