An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the prl_hypervisor module. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer.
