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
Integer overflow in the vmx86 kernel extension in VMware Fusion before 2.0.6 build 196839 allows host OS users to cause a denial of service to the host OS via unspecified vectors.

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 · high confidence

Integer overflow vulnerability in VMware Fusion's vmx86 kernel extension allows a user with access to the host OS to trigger the overflow via unspecified vectors, causing a denial of service condition on the host system.

MitigationUpdate VMware Fusion to version 2.0.6 (build 196839) or later to patch the integer overflow in the vmx86 kernel extension.

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. Confirm VMware Fusion is installed
    Look for VMware Fusion application in /Applications folder or check via command: ls /Applications | grep -i vmware
    Affected if VMware Fusion is not found in the system, the vulnerability does not apply
  2. Identify installed VMware Fusion version
    Open VMware Fusion, go to VMware Fusion menu > About VMware Fusion, or run: defaults read /Applications/VMware\ Fusion.app/Contents/Info CFBundleVersion
    Affected if Version is 1.0, 1.1, 1.1.1, 1.1.2, 1.1.3, 2.0, 2.0.1, 2.0.2, 2.0.3, 2.0.4, or 2.0.5 (or any version <= 2.0.5)
  3. Check if vmx86 kernel extension is loaded
    Run: kextstat | grep vmx86, or look for com.vmware.kext.vmx86 in kernel extension list
    Affected if The vmx86 kext is loaded and the VMware Fusion version is in the affected range
  4. Verify running virtual machines
    Check if any VMs are currently running via: vmrun list, or check Activity Monitor for vmware-vmx processes
    Affected if The vulnerability is triggered via unspecified vectors during VM operations; active VMs increase likelihood of exposure but the version check is definitive

If VMware Fusion version is 2.0.5 or earlier (including all 1.x versions listed), the environment is vulnerable to the integer overflow in the vmx86 kernel extension.
