Hypervisor-memory disclosure via Bluetooth-sharing out-of-bounds read
Published Oct 20, 2023 · Updated Aug 2, 2024
Out-of-bounds read in VMware Workstation before 17.5 and Fusion before 13.5 allows guest OS users to read privileged hypervisor memory. The host Bluetooth device-sharing functionality reads beyond an intended memory boundary; VMware has not disclosed the affected routine or input field. Exploitation requires local administrative privileges inside a virtual machine and exposes hypervisor memory without reported modification or interruption.
