CVE-2024-25621

Local privilege escalation via overpermissive runtime directories

Published Nov 6, 2025 · Updated Nov 6, 2025

Incorrect directory permissions in affected containerd releases allow local users to access protected host data and elevate privileges. The daemon creates its state, CRI, sandbox-controller, and configured temporary directories with group or world traversal or read permissions instead of mode 0700. A local host account can inspect metadata or Kubernetes volume contents, and privilege escalation requires useful content such as a setuid binary in an exposed volume.
