AWS is aware of CVE-2024-21626, an issue affecting the runc component of several open source container management systems. Under certain conditions, an actor could leverage a specially crafted container or container configuration to access files or directories outside the container’s file system namespace.

An updated version of runc that addresses the issue is available for Amazon Linux 1 (runc-1.1.11-1.0.amzn1), Amazon Linux 2 (runc-1.1.11-1.amzn2) and for Amazon Linux 2023 (runc-1.1.11-1.amzn2023). AWS recommends that customers using runc or any container-related software apply those updates or a newer version.
