CVE-2026-22715

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.
