CVE-2026-47262: Linuxfoundation Containerd

Medium severity, CVSS 5.5. EPSS: 0.3% chance of exploitation in the next 30 days.

containerd is an open-source container runtime. Versions prior to 1.7.33, 2.0.10, 2.1.9, 2.2.5 and 2.3.2, contain a vulnerability that allows a maliciously crafted image to cause a Denial of Service (DoS) condition. When creating a container from this image, memory exhaustion occurs, leading to an Out Of Memory (OOM) kill of the containerd process. This renders the container runtime API unavailable and can disrupt clients such as the Docker Engine or Kubernetes control-plane components. This issue has been fixed in versions 1.7.33, 2.0.10, 2.1.9, 2.2.5 and 2.3.2.

Affected products

• Linuxfoundation Containerd: from 1.7.0, before 1.7.33 (fixed in 1.7.33); from 2.0.0, before 2.0.10 (fixed in 2.0.10); from 2.1.0, before 2.1.9 (fixed in 2.1.9); from 2.2.0, before 2.2.5 (fixed in 2.2.5); from 2.3.0, before 2.3.2 (fixed in 2.3.2)
