About this tag
The ipvs load balancing tag covers Microsoft’s tracking of a Linux kernel IPVS vulnerability involving IPv6 extension headers and failed TCP, UDP, or SCTP checksum validation before traffic rewriting. Coverage focuses on CVE-2026-45850 and its relevance to infrastructure beyond the Windows kernel, including Linux load balancers, Kubernetes nodes, WSL-adjacent development environments, and hybrid estates used by Windows organizations. It provides context for how Microsoft security reporting increasingly follows dependencies across mixed operating systems and network platforms, making the tag useful for readers monitoring load-balancing behavior, cross-platform exposure, and infrastructure risks connected to IP Virtual Server deployments.
