🛡️ USN-8473-1 — containerd-stable

containerd-stable vulnerabilities

It was discovered that containerd incorrectly handled HTTP/2 SETTINGS

frames. A remote attacker could possibly use this issue to cause containerd

to enter an infinite loop, resulting in a denial of service. (CVE-2026-33814)

Jakub Ciolek and Kyle Elliott discovered that containerd incorrectly

handled group parsing when creating containers from images. An attacker

could possibly use this issue to cause containerd to consume excessive

memory, resulting in a denial of service. (CVE-2026-47262)

Henry Beberman and Robert Prast discovered that containerd incorrectly

validated image references when importing container checkpoints. An

attacker could possibly use this issue to poison the local image cache and

execute arbitrary code in other pods. (CVE-2026-50195)

Robert Prast discovered that containerd incorrectly propagated labels

from image configurations to containers. An attacker could possibly use

this issue to execute arbitrary code on the host. (CVE-2026-53488)

Yuming Zhang, Song Li, Sangwon Ryu, Henry Beberman, Robert Prast, Kyle

Elliott and Zhenchen Wang discovered that containerd incorrectly validated

symlinked paths when restoring container checkpoints. An attacker could

possibly use this issue to read arbitrary files on the host, resulting in

information disclosure. (CVE-2026-53489)

Robert Prast discovered that containerd incorrectly trusted device

interface annotations when restoring container checkpoints. An attacker

could possibly use this issue to bypass resource allocation restrictions

and inject devices or host mounts into a container. (CVE-2026-53492)
