The flaw lies in VMware\u2019s service-discovery logic, which can execute attacker-controlled binaries from writable paths like /tmp. An unprivileged user who runs a process with a listening socket can have it invoked by the privileged discovery routine, resulting in arbitrary code execution.  Only systems with guest service discovery enabled are affected; those without this feature configured are not exposed.\n\nExploitation requires the service-discovery plugin (open-vm-tools-sdmp) to be installed. Red Hat CoreOS (RHCOS) is not affected, as it only ships the standard open-vm-tools package, which by default, does not include the -sdmp subpackage. Customers concerned about exposure should use the command `rpm -q open-vm-tools-sdmp` to verify whether the impacted package is present on their systems.",
