CVE-2026-95837 is a high-severity vulnerability in containerd, published on 12 Oct 2026. It can only be exploited from the same machine or local network, with no action from the victim. ### Official description containerd is an open-source container runtime. From 2.1.0 until 2.2.7 and 2.3.4, containerd's CRI CreateContainer checkpoint restore is vulnerable because CRIU restores process security state from checkpoint data instead of enforcing the destination ContainerConfig. An attacker who can create a container from a crafted checkpoint can supply restored credentials, capabilities, no_new_privs, and seccomp state. The restored process can run as root with full capabilities and no enforced seccomp filters while CRI status reports the requested configuration. Systems that do not use CRI checkpoint restore are not affected. This issue is fixed in versions 2.2.7 and 2.3.4. Weakness: CWE-269 (Improper Privilege Management) ## Which versions are affected by CVE-2026-95837? 6 open source packages ship an affected version, including github.com/containerd/containerd/v2 and github.com/containerd/containerd. | Package | Ecosystem | Affected | Fixed in | | --- | --- | --- | --- | | `github.com/containerd/containerd/v2` | Go | From 2.1.0 | 2.2.7, 2.3.4 | | `github.com/containerd/containerd/v2` | Go | From 2.1.0 | 2.2.7 | | `github.com/containerd/containerd/v2` | Go | From 2.1.0 | 2.2.7 | | `github.com/containerd/containerd/v2` | Go | From 2.3.0 | 2.3.4 | | `github.com/containerd/containerd/v2` | Go | From 2.3.0 | 2.3.4 | | `github.com/containerd/containerd` | Go | All versions | None | ## How do I fix CVE-2026-95837?

There is no known exploitation of CVE-2026-95837 in the wild and no public exploit code. ## Fix prompt for AI coding agents ```text Check this codebase for CVE-2026-95837 and fix it if it is affected. What it is: CVE-2026-95837 is a high-severity vulnerability in containerd, published on 12 Oct 2026. It can only be exploited from the same machine or local network, with no action from the victim. Exploitation: There is no known exploitation of CVE-2026-95837 in the wild and no public exploit code. Affected packages and fixed versions: - github.com/containerd/containerd/v2 (Go): affected from 2.1.0; fixed in 2.2.7, 2.3.4 - github.com/containerd/containerd/v2 (Go): affected from 2.1.0; fixed in 2.2.7 - github.com/containerd/containerd/v2 (Go): affected from 2.1.0; fixed in 2.2.7 - github.com/containerd/containerd/v2 (Go): affected from 2.3.0; fixed in 2.3.4 - github.com/containerd/containerd/v2 (Go): affected from 2.3.0; fixed in 2.3.4 - github.com/containerd/containerd (Go): affected all versions; no fix listed Task: 1. 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.
