Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
VMware ESXi contains an out-of-bounds read vulnerability. A malicious actor with local administrative privileges on a virtual machine with an existing snapshot may trigger an out-of-bounds read leading to a denial-of-service condition of the host.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

VMware ESXi contains an out-of-bounds read vulnerability that can be exploited by a malicious actor with local administrative privileges on a virtual machine that has an existing snapshot. Successful exploitation leads to denial-of-service of the ESXi host.

MitigationApply VMware security patches for CVE-2024-37086 when available. Review and limit administrative privileges on VMs, and manage snapshot lifecycle to minimize exposure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify ESXi host version
    Run 'esxcli system version get' on the ESXi host or check via vCenter under Host > Configuration > Security Profile > Product Versions
    Affected if Version is 7.0 or 8.0, or VMware Cloud Foundation is between 4.0 and 5.1 (not patched)
  2. Check for existing VM snapshots
    Run 'vim-cmd vmsvc/snapshot.get <vmid>' for each VM, or use the vSphere Client to view VMs with snapshots under Snapshots tab in VM inventory
    Affected if Any VM has one or more existing snapshots (the vulnerability requires an existing snapshot to be present)
  3. Identify users with local administrative privileges on VMs
    Review VM guest OS user accounts with administrator or root privileges, or check if non-administrative users have been granted elevated privileges on VM operating systems
    Affected if There are user accounts with local administrative privileges on VMs that also have snapshots

You are affected if your ESXi version is 7.0 or 8.0 (or Cloud Foundation 4.0-5.1), AND there exists a VM with an existing snapshot, AND a malicious actor could obtain local administrative privileges on that VM.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Upgrade available Upgrade to 5.2 or later
Fixed in 5.2
Interim mitigation

Apply VMware security patches for CVE-2024-37086 when available. Review and limit administrative privileges on VMs, and manage snapshot lifecycle to minimize exposure.

Recommended fix Moderate confidence

Cloud Foundation 5.2+ or ESXi 7.0/8.0 latest patched releases

  1. Identify the current VMware ESXi version installed on the host using the command: esxcli system version get
  2. For Cloud Foundation: Upgrade to version 5.2 or later, which contains the security fix
  3. For standalone ESXi 7.0: Apply the latest ESXi 7.0 security patch from Broadcom support portal (support.broadcom.com)
  4. For standalone ESXi 8.0: Apply the latest ESXi 8.0 security patch from Broadcom support portal (support.broadcom.com)
  5. Before applying updates, ensure all virtual machines have valid backups and snapshots can be restored
  6. After patching, verify the fix by checking the ESXi version matches the patched release
Caveat Major version upgrades (e.g., ESXi 7.0 to 8.0) may require VM compatibility updates and should be tested in a non-production environment first
