CVE-2026-53657

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.

Summary		(es) Lima lanza máquinas virtuales Linux, típicamente en macOS, para ejecutar containerd. Antes de la versión 2.1.3, en una instancia de Lima ejecutándose con el controlador qemu, un usuario arbitrario en la MV podía acceder a /run/lima-guestagent.sock cuando el agente invitado estaba habilitado, lo que podría resultar en la ejecución de comandos arbitrarios con privilegios de root en la MV porque el socket del agente invitado proporciona tunelización para direcciones arbitrarias, incluyendo direcciones de socket Unix para demonios privilegiados como D-Bus. Este problema está solucionado en la versión 2.1.3.
