CVE-2026-41703 is an out-of-bounds read vulnerability in VMware ESX/ESXi, VMware Workstation, and VMware Fusion. An actor possessing virtual-machine deployment privileges can trigger a read outside the intended memory bounds. On ESX/ESXi, this may disclose information and is more likely to cause a denial-of-service condition in the host process. On Workstation and Fusion, the impact is limited to information disclosure.
