      <title>CVE-2026-53493 — Containerd has image-pull DoS via crafted OCI index graph amplification</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-53493</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; containerd&lt;/p&gt;
&lt;p&gt;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. Versions 1.7.36, 2.0.13, 2.2.9, 2.3.6, and 2.4.1 fix the issue.&lt;/p&gt;</description>
