- Platform/SRE — Plan: Three containerd security fixes ship in this patch: two crash-on-pull vectors and a disk-exhaustion flaw (GHSA-hc94-p972-ch66) that could drain host storage on malicious image pulls. None are KEV-listed or actively exploited, but any team running Docker Engine or raw containerd in production should schedule an upgrade to 29.9.1 this sprint.

- Platform/SRE — Plan: CVE-2026-95839 is a security fix in the container runtime underlying every Kubernetes node, but it is not KEV-listed and carries no public exploitation signal, so this does not meet the Act bar. Plan to upgrade containerd to 2.4.2 across node pools this quarter.

- Signals: containerd 2.4 EOL 2027-05-16 · CVE-2026-95839 — CISA KEV: not listed, EPSS n/a, reported by 2 collected sources
- Platform/SRE — Plan: CVE-2026-95839 is not KEV-listed and no active exploitation is reported, but this patch hardens symlink handling, seccomp socket allowlisting, and image reference validation in the container runtime — all within the production-critical containerd path. Schedule an upgrade to 2.3.7 across node pools within your next maintenance window; containerd 2.3 EOL is 2028-04-30, so no forced-upgrade urgency.

- Signals: containerd 2.3 EOL 2028-04-30 · CVE-2026-95839 — CISA KEV: not listed, EPSS n/a, reported by 2 collected sources
- Platform/SRE — Plan: New Docker 29 installs default to the containerd image store, which has different behavior for image layering, multi-platform support, and tooling compatibility; review and test before rolling out Docker 29 on new nodes or golden AMIs to avoid unexpected differences from existing hosts still on the legacy store.
- CI/CD — Plan: Any CI runner provisioning that installs Docker 29 fresh will get the containerd image store by default, which may affect build caching behavior and image layer handling; audit runner provisioning scripts and validate build pipelines against Docker 29 before upgrading runner images.

- Platform/SRE — Plan: Four HTTP/2 CVEs in the Docker daemon (daemon crash, memory exhaustion, flow-control bypass, CPU spike) are fixed in this release; none are KEV-listed and EPSS scores are near zero, so no active exploitation clock, but schedule an upgrade to v29.9.0 if running Docker Engine on cluster nodes or VM fleets.
- CI/CD — Plan: If Docker-in-Docker or a Docker socket is part of your build runners, the same HTTP/2 daemon vulnerabilities apply; plan to update the Docker Engine version in runner images or host provisioning to v29.9.0, no hard deadline but meaningful DoS risk in shared build infrastructure.

- Platform/SRE — Plan: CVE-2026-17106 allows a crafted tar archive to write outside the extraction directory in the Docker engine — real exposure for any host running Moby/Docker, but not KEV-listed and EPSS is 0.00 with no active exploitation evidence. Schedule an upgrade to v25.0.18 this sprint rather than treating it as an emergency.

- Platform/SRE — Plan: This GA release deprecates the containerd.io/runtime-allow-mounts shim annotation (replaced by MountCapabilities extension) and task API address/version fields in runc options; plan migration away from both, though no removal date is confirmed yet.

- Platform/SRE — Plan: containerd 2.4.0 is a GA non-LTS release that removes previously deprecated features, so audit your current deployments for deprecation warnings before upgrading; the 2.3 LTS remains the stability-first choice, and this release’s EOL is 2027-05-16.

- Platform/SRE — Plan: Despite being a patch release, 2.3.4 ships a breaking change: checkpoint restore in CreateContainer is now disabled by default, requiring an explicit config opt-in. Also fixes a memory leak in the OOM watcher and binary protobuf shim corruption. Review workloads using CRIU/checkpoint restore before upgrading; schedule the upgrade this quarter.

- Platform/SRE — Plan: containerd 2.2 reaches EOL on 2026-11-06 (81 days), so plan migration to a supported branch before then; also note this patch disables checkpoint restore in CreateContainer by default, which may break CRIU-based workloads that haven’t set enable_experimental_restore_via_create.

- Platform/SRE — Plan: Two regressions introduced in 29.7.0 — image pulls rejecting hardlink targets and file-permission failures on older kernels — are fixed in 29.7.2; if you upgraded to 29.7.x recently, schedule a patch to 29.7.2 to restore stable image pull behavior.

- Platform/SRE — Plan: Two confirmed regressions patched: image pulls failing for layers with implicit parent directories, and CopyToContainer rejecting valid symlink paths like /var/run. Schedule an upgrade to 29.7.1 if running 29.7.x in production.

- Platform/SRE — Plan: Upgrade Docker Engine to v29.7.0 to patch CVE-2026-17106 (go-archive archive-traversal fix) and resolve two daemon panic bugs in container network cleanup paths; the CVE is not KEV-listed so no hard deadline, but schedule this within the current sprint.

- Platform/SRE — Plan: Five CVEs fixed in Docker Engine including a command injection via git bundle checkout and a directory traversal that can wipe /tmp — no KEV listing or known active exploitation, but the severity warrants scheduling an upgrade to 29.6.2 this sprint.
- CI/CD — Plan: If Docker Engine runs on self-hosted CI runners or build hosts, the git-bundle command injection (CVE-2026-15793) and local-source upload bypass (CVE-2026-15789) are directly relevant to build-time workloads; plan to update runner environments to Docker 29.6.2.
