Guest to host: escaping Docker's hypervisor

Docker has patched a sandbox escape we reported in its hypervisor for Mac: a container can get complete read and write access to the host filesystem by running three lines of bash. Docker Desktop and Docker Sandboxes are both affected. Docker Desktop is only affected if Docker VMM is turned on in Settings. It’s a good thing we found it now, because Docker VMM is scheduled to become the default for Docker Desktop at the end of October 2026.
