Guest traffic interception or interruption via NAT logic
Published Feb 26, 2026 · Updated Feb 26, 2026
Logic flaw in VMware Workstation 17.0 through 25H2 and Fusion 13.0 through 25H2 allows guest OS users to intercept or interrupt peer VM traffic. Broadcom identifies the locus only as NAT network-packet management and has not disclosed the state or validation error that redirects or drops traffic. Exploitation requires administrative privileges inside one guest VM and is bounded to intercepting or interrupting connections of other guest VMs.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
