Last modified

CVE-2026-53657 is a high-severity vulnerability rated 8.2/10 on the CVSS scale. 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. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
