Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

containerd (Go module github.com/containerd/containerd/v2) versions 2.1.0 up to 2.2.7 and 2.3.0 up to 2.3.4 are affected. A container restored through the CRI CreateContainer API from a crafted checkpoint can run with root and full capabilities, ignoring the requested security context and seccomp settings. Upgrade to containerd 2.2.7 or 2.3.4; on unpatched versions, restrict container creation to trusted users and reject images containing checkpoint data.
