Symptoms

Broadcom has published a VMware Security Advisory (VMSA) on several Critical and Important security issues with ESXi 7.0, and 8.0 described in VMSA-2025-0013. They have developed several ESXi patches to resolve these issues. For more information, see:

VxRail Engineering released an updated VxRail Software 8.0.3xx package which includes the fix the issue described in VMSA-2025-0013. Details of this release are outlined below.

 
Note: There are no plans to provide a VxRail Software release for VxRail 7.0.411+ (ESXi 7.0U3) or 8.0.2xx (ESXi 8.0U2).
VxRail environments using these builds must install the ESXi patch manually to obtain the fix.
 

VxRail Engineering approved installing ESXi patches with the fix for these issues on existing VxRail and VMware Cloud Foundation on VxRail (VCF) clusters. Details of these and the process to install them are outlined below.

Cause

There are four issues described in VMSA-2025-0013:

  • VMXNET3 integer-overflow vulnerability (CVE-2025-41236) - CVSSv3 9.3 (Critical)
  • VMware Virtual Machine Communication Interface (VMCI) integer-underflow vulnerability (CVE-2025-41237) - CVSSv3 9.3 (Critical)
  • PVSCSI heap-overflow vulnerability (CVE-2025-41238) - CVSSv3 9.3 (Critical)
  • vSockets information-disclosure vulnerability (CVE-2025-41239) - CVSSv3 7.1 (Important)

For more information about these issues, see the above VMware Security Advisory (VMSA) article.

Resolution

VxRail environments

Status of the issue in VxRail releases:

  • This issue is resolved in VxRail 8.0.361

VxRail engineering recommends all customers upgrade to the above VxRail release to remediate this issue.

Manual remediation of the issue:

  • This issue can be remediated in VxRail 7.0.411 and later releases with the ESXi 7.0U3w patch
  • This issue can be remediated in VxRail 8.0.210 - 8.0.214 releases with the ESXi 8.0U2e patch

A guide to installing the appropriate ESXi patch mentioned above can be found at: How to manually update ESXi Nodes in a VxRail environment

 
Note: There are no workarounds to the issues described in the above VMware Security Advisory (VMSA) article.
 

VMware Cloud Foundation (VCF) on VxRail

Status of the issue in VCF releases:

  • VCF 4.5.x environments should be upgraded to VCF 5.2.x. The ESXi 7.0U3w patch is not supported in VCF 4.5.x
  • This issue is resolved in VCF 5.2.2 which includes VxRail 8.0.361
 
Note: Attempting to install the ESXi 7.0U3w patch on a VCF 4.5.x environment is not supported and may prevent upgrades or migrations to VCF 5.2.x.
 

Recommended upgrade paths when manually updating clusters

The following are the suggested upgrade paths:

  • VxRail 8.0.210 - 8.0.214 can apply the ESXi 8.0U2e patch
  • VxRail 7.0.411 - 7.0.550 can apply the ESXi 7.0U3w patch. If clusters are running VxRail 7.0.410 or lower, the cluster must upgrade to VxRail 7.0.411 release or later before applying a patch
  • VxRail 8.0.000 - 8.0.120, 8.0.230, and 8.0.240 must upgrade to VxRail 8.0.361 or later

VxRail Engineering management has provided the following statement regarding support for nodes which are updated outside a VxRail upgrade.

"Customers that manually apply the relevant security patches can continue to expect full support for their VxRail system"
