CVE-2026-63125

Incus is a system container and virtual machine manager.

Published Aug 21, 2026 · updated Oct 15, 2026

Incus is a system container and virtual machine manager. Prior to version 7.3.0, an unprivileged, project-confined Incus user (a non-admin TLS/RBAC identity with and ) can execute arbitrary code as root on the host. A crafted image ships as a symlink to a host file. When the root daemon writes the instance's backup file, it follows the symlink. Version 7.3.0 patches the issue.
