A flaw was found in crun. During terminal setup, when the OCI configuration does not mount /dev, crun unlinks and recreates /dev/console without preventing symlink follows. A malicious image can make /dev/console a symlink so that crun creates a root-owned file outside the container rootfs. Affected versions are crun 1.29.1 and earlier. This is not CVE-2026-47766, which addressed following a rootfs /dev directory symlink and was fixed in crun 1.28. No fixed release is published yet.
