SUSE CVE-2026-53493

containerd is an open-source container runtime. Prior to versions 1.7.36, 2.0.13, 2.2.9, 2.3.6, and 2.4.1, a crafted OCI index graph can force very high CPU/memory usage during PullImage before container start, causing long ContainerCreating stalls and, at larger sizes, node/runtime instability...

GHSA-PG57-6JWG-Q645 Containerd has image-pull DoS via crafted OCI index graph amplification

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 PullImage operation, the recursive traversal and processing of child...

Excessive Iteration

Overview Affected versions of this package are vulnerable to Excessive Iteration in the PullImage process. An attacker can cause excessive CPU and memory consumption by supplying a crafted OCI image index with deeply nested or heavily fanned-out descriptor graphs, leading to prolonged stalls and...
