Lima: An arbitrary user in a QEMU VM could gain the root privilege in the VM via the guest agent socket

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

Lima launches Linux virtual machines, typically on macOS, for running containerd. Prior to 2.1.3, on an instance of Lima running with the qemu driver, an arbitrary user in the VM could access /run/lima-guestagent.sock when the guest agent is enabled, which could result in running arbitrary commands with root privileges in the VM because the guest agent socket provides tunneling for arbitrary addresses, including Unix socket addresses for privileged daemons like D-Bus. This issue is fixed in version 2.1.3.

### 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. ### Workarounds - On macOS hosts, use `vz` driver instead of `qemu` (`limactl create --vm-type=vz`. Default since v1.0.) - Or, disable the guest agent (`limactl create --plain`)
