CVE-2025-52565 is a container escape vulnerability in runc, the OCI reference runtime, affecting versions 1.0.0-rc3 through 1.2.7, 1.3.0-rc.1 through 1.3.2, and 1.4.0-rc.1 through 1.4.0-rc.2. The flaw is caused by insufficient validation during the bind-mount of the container console device from /dev/pts/$n to /dev/console during container initialization. An attacker can exploit races or symlink redirection so that runc bind-mounts an unintended target onto a path writable from inside the container, including paths that would normally later be masked or made read-only. Because this mount occurs after pivot_root(2) but before maskedPaths and readonlyPaths protections are applied, the attacker can bypass intended filesystem restrictions inside the container. The issue is conceptually similar to CVE-2025-31133 but specifically targets console setup for containers that allocate a console.

A runC vulnerability affecting versions 1.0.0-rc3 and later, where insufficient validation of the /dev/pts/$n to /dev/console mount during container initialization allows attackers to redirect the mount and gain write access to protected procfs files, enabling security bypass and possible host compromise.
A flaw in runc's handling of /dev/console bind-mounts allows attackers to use symlinks to gain write access to procfs files, leading to container breakout.
A vulnerability in runC that allows container escape via writable access to procfs entries, enabling attackers to break out of Docker and Kubernetes containers.
A vulnerability in runC where /dev/console bind mount can be redirected via race conditions or symlinks, exposing writable access to critical files and enabling container breakout.
