Researchers Uncover Critical runC Bugs Allowing Full Container Escape
Security researchers have revealed three serious vulnerabilities in runC, the Open Container Initiative (OCI)-compliant runtime that powers platforms such as Docker and Kubernetes, which could allow attackers to break container isolation and gain control of the host system. The flaws, tracked as CVE-2025-31133, CVE-2025-52565, and CVE-2025-52881, stem from weaknesses in how runC manages temporary bind…

Runtime bugs break container walls, enabling root on Docker hosts
Console and Write-Gadget Lurkers: CVE-2025-52565 & CVE-2025-52881: The second vulnerability, tracked as CVE-2025-52565, targets “/dev/console” bind-mount handling. An attacker can replace the target path with a symlink, which will cause runc to bind-mount the wrong target, allowing the attacker to gain write access to procfs paths.”As with CVE-2025-31133, this happens after pivot_root(2) and so cannot…
