Broadcom has implemented several significant changes regarding its VMware software suite. In early September 2026, the company released VMware Workstation Pro 26H1u1 to patch critical security vulnerabilities, specifically addressing integer-overflow and stack-based buffer overflow flaws that could enable VM-escape attacks. This update also introduced automated Secure Boot Platform Key remediation.

Shortly thereafter, Broadcom ended public access to the VMware Virtual Disk Development Kit (VDDK), which is used for virtual disk backup, recovery, and cloning. The removal of public downloads impacts migration tools from competitors such as Nutanix, Red Hat, and Microsoft. While Broadcom stated that vendors are entitled to change SDK distribution methods, access to the VDDK is now restricted to select Technology Alliance Partners.
