Hello, Our UC-KLEE tool discovered a memcpy() read overrun bug in dg_dispatch_as_host() (drivers/misc/vmw_vmci/vmci_datagram.c). This bug may allow a malicious user to leak private kernel heap data across the VMware VMCI interface (in a nearly identical fashion to the OpenSSL Heartbleed vulnerability from 2014), but the impact is probably minimal since this interface is only used for local communication.
