Lima

v2.1.3Kubernetes Core

Lima v2.1.3 is a security-focused patch release fixing two CVEs: a privilege escalation in QEMU VMs and multiple containerd CVEs bundled via nerdctl v2.3.3. Upgrade promptly.

• securityPatch QEMU privilege escalation (CVE-2026-53657) immediately

  Any unprivileged user inside a QEMU-backed Lima VM could gain root inside that VM by abusing the guest agent socket. If you share Lima VMs among multiple users or run untrusted workloads, this is high priority. Upgrade to v2.1.3 and restart affected VMs.

• securitycontainerd CVE batch via nerdctl v2.3.3 — upgrade required

  Five CVEs in containerd are fixed in the bundled nerdctl v2.3.3 (containerd v2.3.2). If your Lima instances run container workloads, the old containerd is exposed. Upgrade Lima and recreate or restart VMs to pick up the new nerdctl binary.

• breakingcontainerd.user defaults changed for non-Linux guests

  Lima no longer sets containerd.user=true by default on non-Linux guests (macOS, Windows). If you relied on rootless containerd on those platforms without explicitly setting this, validate your VM config after upgrading and set containerd.user=true explicitly if needed.
