Advisory details

Impact

On an instance of Lima running with qemu driver, an arbitrary user in the VM could access /run/lima-guestagent.sock when the guest agent is enabled.

This could result in running an arbitrary command with the root privileges in the VM (not on the host), as lima-guestagent.sock provides the tunneling service for an arbitrary address, including a Unix socket address for privileged daemons like D-Bus.

This vulnerability is not exploitable on vz driver, as the guest agent uses vsocks instead of Unix sockets.

Patches

Patched in Lima v2.1.3 (8a45892378d22f40505c31a38f786a07701b6d50)

[!NOTE] The default user account in the VM can still run an arbitrary command as the root via the guest agent socket. This is not a vulnerability, as the user can already run an arbitrary command with sudo by design.
