CVE-2026-22717: VMware Workstation out-of-bound read vulnerability

Out-of-bound read vulnerability in VMware Workstation 25H1 and below on any platform allows an actor with non-administrative privileges on a guest VM to obtain limited information disclosure from the machine where VMware Workstation is installed.

Security readout for executives and security teams

Plain-English summary

CVE-2026-22717 is a low-severity VMware Workstation information disclosure issue. A non-administrative user inside a guest VM may be able to read limited information from the host machine running Workstation. The business impact appears limited, but organizations using Workstation for sensitive workloads should still track remediation.

Executive priority

Handle through normal vulnerability management, not emergency response. Prioritize environments where Workstation hosts process sensitive information or run untrusted guest VMs. The issue is low severity and limited to information disclosure, but host-to-guest boundary weaknesses deserve timely cleanup.

Technical view

The issue is an out-of-bounds read, classified as CWE-125, affecting VMware Workstation 25H1 and below on any platform. CVSS 3.1 score is 2.7: local attack vector, high complexity, user interaction required, changed scope, low confidentiality impact, and no integrity or availability impact.

Likely exposure

Exposure is limited to environments running VMware Workstation 25H1 or earlier where guest VM users are present. The attacker position is inside a guest VM, not remote network access to the host.

Exploitation context

The provided sources do not indicate active exploitation, and the CVE is not listed as CISA KEV. Exploitation appears constrained by local guest access, high attack complexity, and required user interaction. Public exploit status is not established in the provided sources.

Researcher notes

The CVE metadata says Workstation 25H1 and below are affected, while 25H2 is marked unaffected. Available details do not describe the vulnerable component, trigger condition, or exact user interaction requirement. Avoid assuming exploitability beyond limited host information disclosure from a guest VM.

Mitigation direction

  • Identify VMware Workstation installations and versions across endpoints and lab systems.
  • Prioritize systems running Workstation 25H1 or earlier.
  • Review the Broadcom advisory for the vendor-recommended update path.
  • Move affected systems to an unaffected release where operationally feasible.
  • Limit untrusted guest VM access until remediation is complete.

Validation and detection

  • Confirm installed VMware Workstation version on managed endpoints.
  • Verify whether each system is 25H1 or earlier, or an unaffected release.
  • Check vulnerability scanner results against CVE-2026-22717.
  • Review guest VM access for non-administrative users on affected hosts.
  • Document remediation status and exceptions for Workstation systems.

Out-of-bounds Read

Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
