Security readout for executives and security teams

Plain-English summary

CVE-2026-22716 affects VMware Workstation 25H1 and below. A non-administrative user inside a guest VM can trigger a flaw that terminates certain Workstation processes. The known impact is disruption and limited integrity/availability impact, not confirmed host takeover.

Executive priority

Treat as a moderate operational risk. It is not currently known to be exploited, but affected Workstation systems used with untrusted guest users should be updated or restricted promptly to reduce disruption risk.

Technical view

This is a CWE-787 out-of-bounds write in VMware Workstation. The CVSS 3.1 score is 5.0, with local attack vector, low complexity, changed scope, and user interaction required. The source states affected versions are Workstation 25H1 and below on any platform; 25H2 is listed as unaffected.

Likely exposure

Organizations using VMware Workstation 25H1 or earlier, especially where guest VMs are accessible to non-administrative or less-trusted users, are the likely exposure group. Workstation 25H2 is listed as unaffected in the provided data.

Exploitation context

The provided sources do not show active exploitation, and the CVE is not listed as KEV. Exploitation requires local access from a guest VM context and user interaction per the CVSS vector. Public details are limited, so exact triggering conditions are not described.

Researcher notes

The source bundle has limited technical detail. The key ambiguity is version mapping: the description names 25H1 and below as affected, while the affected record lists 25H2 as unaffected. No exploit code, active exploitation, or deeper root-cause details are provided.

Mitigation direction

  • Identify VMware Workstation installations and versions across endpoints.
  • Prioritize systems running Workstation 25H1 or earlier.
  • Move to vendor-listed unaffected Workstation 25H2 where applicable.
  • Review Broadcom advisory 36986 for official remediation guidance.
  • Restrict access to guest VMs from untrusted users until remediated.

Validation and detection

  • Confirm installed VMware Workstation version on managed endpoints.
  • Verify whether any instance is 25H1 or earlier.
  • Check Broadcom advisory 36986 for affected build details.
  • Review crash logs for unexpected Workstation process termination.
  • Document systems hosting guest VMs used by non-administrative users.
