CVE-2026-47262 is a medium-severity denial of service vulnerability in containerd, published on 1 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim. ### Official description 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. Weakness: CWE-400 (Uncontrolled Resource Consumption) ## Which versions are affected by CVE-2026-47262? 12 open source packages ship an affected version, including github.com/containerd/containerd/v2 and github.com/containerd/containerd.

Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
