Telco Cloud Platform folds into VCF, and an open-source stand-in for VDDK appears

  • Keep the Brotli workaround on SDDC Manager, and finish the ESX logging fix this week. VMSA-2026-0008.1 still lists every SDDC Manager fix as "Patch pending", so KB 460732 on 9.1.1 or KB 460734 on 9.0.x, 9.1.0 and 5.2.x is what protects you. BleepingComputer reports a US federal deadline of 10 November for the underlying Brotli flaw, and GBHackers reports 11 November for the ESX logging flaw CVE-2026-41709, whose fixed builds are in the VMSA-2026-0006 matrix.
  • Check ClusterClass and Supervisor versions before you move to VKS 3.8. The VKS 3.8 release notes need VKS 3.5.0 or later and a Supervisor Kubernetes version of at least 1.33, remove ClusterClasses builtin-generic-v3.1.0 to v3.3.0, and ask for every cluster to be on ClusterClass 3.6.0 or later before you upgrade the Supervisor to 9.1, or you may get system-initiated rolling updates. Today's deep dive has the rest.
  • Keep the vsphere provider pinned to ~> 2.17 if Terraform manages your Supervisor namespaces. The CHANGELOG still shows 2.18.0 as not released, with storage_policies on vsphere_namespace replaced by storage_policy blocks. Nothing has shipped yet, so there's time to plan the change.
  • Security No new VMSA
  • Releases & KBs All quiet
  • Terraform & Packer Nothing new
  • Next deadline 10 Nov
