containerd up to 2.3.1 Image denial of service

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

The product does not release or incorrectly releases a resource before it is made available for re-use. Impacted is availability. The summary by CVE is:

containerd is an open-source container runtime. Versions prior to 1.7.33, 2.0.10, 2.1.9, 2.2.5 and 2.3.2, contain a vulnerability that allows a maliciously crafted image to cause a Denial of Service (DoS) condition. When creating a container from this image, memory exhaustion occurs, leading to an Out Of Memory (OOM) kill of the containerd process. This renders the container runtime API unavailable and can disrupt clients such as the Docker Engine or Kubernetes control-plane components. This issue has been fixed in versions 1.7.33, 2.0.10, 2.1.9, 2.2.5 and 2.3.2.

The weakness was published by Jakub Ciolek. It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2026-47262. The attack may be initiated remotely. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1499 according to MITRE ATT&CK.

The vulnerability scanner Nessus provides a plugin with the ID 321801 (Linux Distros Unpatched Vulnerability : CVE-2026-47262), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 1.7.33, 2.0.10, 2.1.9, 2.2.5 or 2.3.2 eliminates this vulnerability.

The vulnerability is also documented in the databases at Tenable (321801) and CERT Bund (WID-SEC-2026-2009). Be aware that VulDB is the high quality source for vulnerability data.
