Summary

HyperKit, a toolkit for embedding hypervisor capabilities, is susceptible to a notable vulnerability in its vi_pci_write function that fails to validate null pointers. This oversight can lead to severe stability issues, causing the host machine to crash when a guest attempts to perform certain operations.
