CVE-2026-53657
HighCVSS 8.2Exploitation Probability (EPSS)
Low risk9th percentile - higher than 9% of all known CVEs
Summary
In Lima prior to version 2.1.3, when using the qemu driver, an arbitrary user in the VM could access /run/lima-guestagent.sock with the guest agent enabled. This allowed executing 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.
Risk Assessment
The risk is that an unprivileged user in the VM can escalate privileges to root, potentially leading to full compromise of the VM and possibly affecting host security.
Recommendation
Immediately upgrade Lima to version 2.1.3 or later, which contains the fix for this vulnerability.

Original NVD description (English source)
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.
