Crun is a lightweight container runtime focused on OCI-compliant execution, with a narrow product footprint centered on the crun binary itself but occupying a strategic position in container orchestration and edge-deployment scenarios. Its observed vulnerability signal clusters around file-access and permissions handling, with recurrent issues in symlink resolution, privilege management, and default permission assignments that are characteristic of system-level tools operating on untrusted or partially controlled filesystems. Live severity, exploitation, and exposure counts are shown alongside this summary.
