Latest News from the Web

Weekend edition · archive

It's a gentle start to the weekend, with one change that will please anyone stuck mid-upgrade. KB 457944, the article about Supervisor control plane VMs disappearing from inventory after an upgrade to VCF 9.1 or 9.1.1, now names its fix: 9.1.1.0100, build 25784172, the vCenter and Supervisor patch level from 12 October. If you were waiting on that KB before upgrading, you can stop waiting.

There's no new VMSA today, and SDDC Manager is still waiting for its Brotli patch, so keep the workaround in place.

Elsewhere, Ansible's vmware.vmware_rest collection shipped 5.1.0 with a couple of deprecations, Virtually Speaking has a new episode on KubeVM Service, and today's deep dive looks at Protection and Recovery in VCF 9.1, the product you may still know as Live Recovery.

This is an earlier briefing. Read today's Latest Tech News →

  • Security No new VMSA SDDC Manager's Brotli patch is still pending
  • Releases & KBs One KB worth reading KB 457944 now names its fix
  • Terraform & Packer Nothing new vcf 0.19.0 is still the one for VCF 9.1.1
  • Next deadline 10 Nov CISA deadline for the Brotli flaw, per press

Key Takeaways

  • Urgent Keep the Brotli workaround on SDDC Manager, and get the ESX logging fix in before Wednesday. VMSA-2026-0008.1 still shows "Patch pending" for every SDDC Manager version, so KB 460732 on 9.1.1 (or KB 460734 on 5.2.x, 9.0.x and 9.1.0) is what's protecting you. Press reports put the US federal deadlines at 10 November for the Brotli flaw and 11 November for ESX CVE-2026-41709, whose fixed builds are in the VMSA-2026-0006 matrix.
  • Before upgrading If you're heading to VCF 9.1.1 with Supervisor enabled, land on the 9.1.1.0100 patches or later. KB 457944 now says the missing Supervisor control plane VMs issue is fixed in 9.1.1.0100 build 25784172, and that upgrading to that version or later avoids it. While you're planning, KB 458474 is a reminder that a distributed switch spanning 9.0.1 and 9.1 hosts can throw "High pNic error rate detected" alarms until you finish the upgrade.
  • This month If you run vSphere Standard or Enterprise Plus 8 in the EEA, get the extended-support terms in writing before you count on 2028. Broadcom's portfolio post keeps both editions on sale to 31 October 2027 with extended support until the earlier of your subscription end or 31 October 2028, but doesn't say what extended support covers. Everyone else is still working to the 11 October 2027 end of general support in KB 459135.
  • Watch Run your vmware.vmware_rest playbooks against 5.1.0 and look for deprecation warnings. 5.1.0 deprecates vcenter_vm_hardware and vcenter_vm_hardware_info. Nothing is removed yet, but after the large removals in 5.0.0 (see the CHANGELOG) it's worth knowing which tasks will need moving to vmware.vmware next.
  • Lab Keep Workstation and Fusion on 26H1u1 if your nested labs live on a laptop. VMSA-2026-0007 fixes two guest-to-host flaws (9.3 and 8.1) in 25H2 and 26H1, with no workarounds, and nested ESX VMs with VMXNET3 adapters are exactly the kind of guest it's about.

Security Advisories Latest four

There's no new VMSA today, so these are the four most recently released or updated advisories; Broadcom's advisory portal has the rest. VMSA-2026-0008.1 is still waiting for its SDDC Manager patch, and vCenter CVE-2026-59310 in VMSA-2026-0006 remains the most important fix if you haven't applied it. The OpenSSH flaw now tracked as CVE-2026-123158 ("SSHole", CVSS 8.1 per SecurityWeek) only affects musl-based systems with PAM disabled, such as Alpine, and Broadcom hasn't published a statement on it. There's still no Broadcom impact statement for the Linux kernel TCP flaw CVE-2026-98432 either.

VMSA-2026-0008.1 Critical Open Rev .1 · 28 Oct 2026

Node.js, as used in SDDC Manager, has a Brotli decoder out-of-bounds write that an attacker with network access to SDDC Manager could use to run code. It is critical (9.8) on SDDC Manager 9.1.1 and important (7.5) on 9.0.x, 9.1.0 and 5.2.x; revision .1 on 28 Oct clarified the impacted products in the response matrix. Every fixed version in the matrix is still "Patch pending", and the newest SDDC Manager patch on TechDocs, 9.1.1.0200, doesn't mention it. Broadcom's portfolio statement KB 460791 says SDDC Manager in VCF 9.1.1 is the only critically affected product. BleepingComputer [Press] reports CISA added the underlying Brotli flaw to its KEV catalogue on 27 Oct with a federal deadline of 10 Nov; the Broadcom advisory itself makes no statement on exploitation. Issue date 27 Oct 2026.

  • CVE-2026-111497 9.8 SDDC Manager Node.js Brotli · 9.8 on 9.1.1, 7.5 elsewhere · reported KEV 27 Oct

DoApply KB 460732 on 9.1.1 or KB 460734 on 5.2.x, 9.0.x and 9.1.0, keep SDDC Manager reachable only from trusted admin hosts, and subscribe to the advisory so you see the patch the day it lands.

VMSA-2026-0007 Critical Open Initial · 3 Sep 2026

For desktop hypervisors: Workstation 25H2 and 26H1 and Fusion 25H2 and 26H1, CVSSv3 8.1 to 9.3. Both CVEs need local admin rights inside a guest and can lead to code execution on the host. There are no workarounds and the advisory makes no statement on exploitation.

  • CVE-2026-59346 9.3 VMXNET3 integer overflow
  • CVE-2026-59347 8.1 HGFS stack overflow

DoUpdate Workstation and Fusion to 26H1u1, especially if you run nested labs on a laptop.

VMSA-2026-0006.2 Critical Exploited Open Rev .2 · 19 Aug 2026

Still the one to prioritise. It covers vCenter, ESX, Workstation and Fusion (and so VCF, VVF and Telco Cloud), CVSSv3 2.7 to 9.8, with no workarounds. CISA added vCenter CVE-2026-59310 to its KEV catalogue on 18 Aug 2026 with known ransomware use. Security Affairs [Press] reports CISA added the ESX logging flaw CVE-2026-41709 on 28 Oct with a federal deadline of 11 Nov; it has its own fixed builds in the matrix. The Broadcom advisory itself makes no statement on exploitation. First published 29 Jul 2026; revision .2 on 19 Aug added 7.0 patch guidance for the critical issues.

On 9.1 the matrix lists ESXi-9.1.0.0200-25557999 for CVE-2026-47876 and ESXi-9.1.0.0-25370933 for the other two. On 8.0, ESXi80U3k-25595708 fixes CVE-2026-47876, U3i-25205845 CVE-2026-41703 and U3j-25429389 CVE-2026-41709; ESXi80U2f-25626445 covers only CVE-2026-47876. For VCF 5.x the matrix lists 5.2.4 for CVE-2026-41709.

VMSA-2026-0005.1 Critical Open Rev .1 · 7 Aug 2026

If you run Avi Load Balancer (including for VKS or VCF Automation), this one matters. Seven CVEs, CVSSv3 7.1 to 9.8, no workarounds; the worst, CVE-2026-47865, is an authentication bypass on the Avi control plane. The advisory makes no statement on exploitation. First published 14 Jul 2026; revision .1 on 7 Aug added the 22.1.7-2p12 patch.

  • CVE-2026-47865 9.8 control-plane auth bypass
  • CVE-2026-47871 8.8 directory traversal
  • CVE-2026-47867 8.7 RCE

KB Articles & Known Issues One KB worth reading

The other articles we follow haven't moved. KB 460732, KB 460734 and KB 460791 still name no fixed SDDC Manager version; KB 460199 on the eMudhra certificate compromise still promises fixes "in upcoming product releases"; KB 458671 (NSX Manager startup with host-based agent VM services) still offers only the proton timeout workaround; KB 452660 (NSX SCRX after a 9.0.1 to 9.1.1 upgrade) still points to an upcoming NSX version; and KB 456305 (VCF Operations certificate alerts) still has a fix planned for an upcoming release.

  • KB 457944: Supervisor control plane VMs missing from inventory after a VCF 9.1 upgrade Broadcom KB Updated Official The resolution now says the issue is fixed in 9.1.1.0100 build 25784172 and that upgrading to that version or later avoids it; until recently it only promised "the next release of VCF 9.1.1". That matches the Supervisor 9.1.1.0100 release notes, so if you upgrade from 8.0 U3 or 9.0.x, target the 12 October patches rather than plain 9.1.1.
  • KB 458474: "High pNic error rate detected" alarms during a 9.0.1 to 9.1 upgrade Broadcom KB Undated Official While a distributed switch spans hosts on 9.0.1 and 9.1, upgraded hosts can raise high receive-error alarms on their physical NICs. Broadcom's answer is to finish the job: upgrade the remaining hosts and the distributed switch to 9.1, after which the alarms stop. Worth knowing so a rolling upgrade doesn't send you chasing cabling faults.

Releases & Release Notes Nothing new

No new VCF patches since 26 October. The 9.1.1.x patch index still tops out at SDDC Manager 9.1.1.0200, vCenter, ESX and NSX 9.1.1.0100, VCF Operations and VCF Automation 9.1.1.0200 and vSAN File Services 9.1.1.0200; the SDDC Manager patch page still has no Brotli fix; and Async Releases shows no 9.1.2 or 9.2 line. Avi is still on 32.1.4 (13 Oct), VKS on 3.8.0, VMware Tools on 13.1.6 and Protection and Recovery on 9.1.1.0100 (12 Oct).

Automation & IaC

Terraform & Packer Nothing new

Nothing new from the providers or Packer plugins today. vcf 0.19.0 is still the one to use for VCF 9.1.1, per the README, and the vsphere provider's CHANGELOG still lists 2.18.0, with its storage_policies to storage_policy breaking change on vsphere_namespace, as not released. A ~> 2.17 pin remains the safe choice if Terraform manages your Supervisor namespaces.

Automation & API Ecosystem One release

Elsewhere it's steady: vmware.vmware 2.13.0 (5 Nov), VCF.PowerCLI 9.1.1, govmomi 0.56.2 and pyVmomi 9.1.1.0 are still current.

  • vmware.vmware_rest 5.1.0 deprecates the VM hardware modules GitHub (ansible-collections) 6 Nov Official Released on 6 November as a minor version, as reviewers had asked, because it deprecates vcenter_vm_hardware and vcenter_vm_hardware_info. It also adds request metadata to the REST logs, which helps when you're debugging a failing task. No new modules and nothing removed this time.

Nested Lab Corner All quiet

Nothing new for labs this weekend. The Holodeck 9.1 release notes still list VCF 9.1.0.0, 9.0.x and 5.2.x as supported, so deploying straight to 9.1.1 or its patches in Holodeck remains an unsupported workaround.

Deep Dive of the Day

Protection and Recovery in VCF 9.1: what replaced Live Recovery, and the traps in moving to it

If your disaster recovery runbooks still say "Live Recovery", it's worth catching up on the name change first. Per the 9.1 release notes, VMware Live Recovery "has been renamed and integrated into VMware Cloud Foundation (VCF) as Protection and Recovery", and it now covers operational recovery, disaster recovery, cyber recovery and multi-tenant DR through VCF Automation. Version 9.1 went GA on 12 May 2026 (build 25367487), and the newest patch is 9.1.1.0100 from 12 October (build 25753785), which the notes describe only as security enhancements.

The moving parts will look familiar. There's a Protection and Recovery appliance, a scale-out appliance and a proxy, plus a VCF Operations management pack and a REST API gateway. Underneath, you choose a replication engine: vSphere Replication (host-based, and able to protect VMs on vSAN without a storage replication adapter), vSAN snapshots with local and replicated retention, or array-based replication through SRAs. New in 9.1, vSAN replication works from any source storage as long as the target is vSAN ESA, snapshot schedules get daily, weekly and monthly retention, protection groups can pick up members by tag, and you can seed from an existing replica so only the changes cross the wire.

The headline feature is cyber recovery. Instead of failing over to whatever the last replica holds, you recover from vSAN snapshots into an isolated clean room, with push-button network isolation through vDefend and integrated EDR to check what you're bringing back. Several vCenter sites can replicate to a single cyber recovery site. Duncan Epping's short demo on Yellow Bricks walks through a ransomware recovery and notes the Carbon Black and CrowdStrike integrations, which is the quickest way to see the workflow end to end.

Upgrades are where people get caught. Both sites need vSphere 8.0 Update 3 or later. Coming from Live Site Recovery 9.0.2.3, vSphere Replication 9.0.2.3 or vSAN Data Protection 8.0 U3, you deploy the 9.1 appliance on both sites first, and moving vSphere Replication to 9.1 means reconfiguring every replication as enhanced replication, so budget for that rather than treating it as an in-place bump. Two things are also on their way out: 9.1 is the last release that supports vSphere Virtual Volumes and the last with the VCF Operations orchestrator plug-in. Broadcom recommends moving vVols replications to array-based replication, and moving orchestrator workflows to the REST API gateway or the DR REST plug-in.

Check the limits before you design around it. 4Kn datastores and PMem aren't supported, NFS 4.1 datastores work with vSphere Replication but not array-based replication, the largest disk is 62 TB, one management server handles up to 5,000 replicated VMs, and VMs with IOFilter storage policies can't be replicated. A few known issues matter in labs as much as production: if you switch a cluster's vSphere Lifecycle Manager image to 9.1 without remediating, then back to 9.0.x, the next remediation can remove the hbr-agent VIB and leave hosts unable to replicate (restart the hms service from the appliance management interface to recover), so don't flip images back and forth; pairing several services at once can fail, so pair them one at a time; and staging many VMs at once in a cyber recovery can hit ESX kernel memory limits, so stage in smaller batches. If a ransomware failover fails, the notes say to run revertCurentImage on that replication before you retry.
