v1.7.35→v1.7.36Containerd has image-pull DoS via crafted OCI index graph amplification
CVE-2026-53493 / GHSA-pg57-6jwg-q645
More information
Details
Impact
A vulnerability exists in containerd's image pull handlers where a crafted OCI image index containing deeply nested or heavily fanned-out descriptor graphs can cause unbounded CPU and memory consumption. During the
PullImageoperation, the recursive traversal and processing of child descriptors lack sufficient depth and breadth limits, and fail to adequately deduplicate identical descriptors. This unbounded traversal leads to excessive resource allocation.Consequently, pulling a malicious image reference can result in prolonged stalls during container creation and significant resource pressure on the host system. This issue occurs entirely during the image pull phase, prior to any container execution.
Patches
This bug has been fixed in containerd 2.4.1, 2.3.6, 2.2.9, 2.0.13, and 1.7.36. Users should update to these versions to resolve the issue.
Workarounds
There are no known workarounds for this issue. Users are advised to only pull trusted images from known registries until the patch can be applied.
