Short explanation

A vulnerability in the containerd CRI plugin allows checkpoint restore operations to bypass the destination ContainerConfig and restore process security states directly from checkpoint data.

Why does it matter?

Attackers can use a crafted checkpoint to bypass restrictions and execute processes as root with full capabilities.

What should be done?

Follow vendor security advisories
Update to fixed versions as advised by the vendor
Review environments where CRI checkpoint restore is enabled

Show the technical text from the sources

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.
