CVE-2024-22255
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 · uneditedVMware ESXi, Workstation, and Fusion contain an information disclosure vulnerability in the UHCI USB controller. A malicious actor with administrative access to a virtual machine may be able to exploit this issue to leak memory from the vmx process.
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 confidenceVMware ESXi, Workstation, and Fusion contain an information disclosure vulnerability in the UHCI USB controller. A malicious actor with administrative access to a virtual machine may exploit this issue to leak memory from the vmx process, potentially exposing sensitive host-level information.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify VMware product and versionRun 'vmware -v' on the host system to determine the installed VMware product (Workstation, Fusion, or ESXi) and its exact version number. For ESXi, you can also use 'esxcli system version get' or check the vSphere Client login screen.Affected if The product is Workstation version >= 17.0.0 and < 17.5.1, Fusion >= 13.0.0 and < 13.5.1, ESXi 7.0 or 8.0, or Cloud Foundation version >= 4.0 and <= 5.0
-
Verify UHCI USB controller is attached to any VMFor Workstation/Fusion: Open each VM settings and inspect the USB Controller device. For ESXi: Use the vSphere Client to view VM configuration, expand the USB controller section, and check if the controller type is set to UHCI. Alternatively, examine the VM's .vmx file for 'usb_xhci' or 'usb' controller settings.Affected if A UHCI USB controller is present and attached to any virtual machine on the affected host
-
Confirm administrative access to guest VMs existsReview who has administrator or root-level access to the virtual machines running on this host. This vulnerability requires a malicious actor with administrative privileges inside the guest VM to exploit the UHCI controller.Affected if Non-trusted users have administrative/root access to guest virtual machines on this host
Your environment is affected if you run an affected VMware product version AND have a UHCI USB controller attached to any virtual machine AND non-trusted users have administrative access to those VMs.

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.
dbcve · scoped13.5.117.5.1
Apply vendor-provided patches for ESXi, Workstation, and Fusion. Limit administrative access to virtual machines to trusted personnel only, as this is a required attack precondition.
Workstation: 17.5.1+ | Fusion: 13.5.1+ | ESXi: Apply VMSA-2024-0006 patch | Cloud Foundation: Apply corresponding patch
- Identify the affected VMware product (ESXi, Workstation, Fusion, or Cloud Foundation) in your environment
- Determine the current installed version using the product's built-in version information
- For VMware Workstation: Upgrade to version 17.5.1 or later
- For VMware Fusion: Upgrade to version 13.5.1 or later
- For VMware ESXi: Apply the appropriate patch from VMware security advisory VMSA-2024-0006 or later, or upgrade to a patched ESXi version
- For VMware Cloud Foundation: Apply the appropriate patch or upgrade to a patched Cloud Foundation version
- Restart the virtual machines if required after applying patches
- Verify the fix by checking the updated version
