CVE-2025-52565 is an improper link-resolution vulnerability in runc console setup. Affected runc releases insufficiently validate the pseudoterminal source used to establish a container console bind mount. An attacker can replace that source with a symbolic link, causing runc to mount the link target at a location writable from the container, including content ordinarily masked or read-only. The vulnerable operation occurs after pivot_root, preventing direct host-file writes through this flaw, but writable procfs targets can enable host or container denial of service and container escape.

A high-severity runc container-isolation flaw caused by insufficient validation during the bind mount of a pseudo-terminal device to /dev/console. It can enable host denial of service or container escape through a writable copy of /proc/sysrq-trigger or /proc/sys/kernel/core_pattern.
A high-severity runc container-runtime flaw caused by insufficient validation of a console-related bind mount. A local attacker can obtain a writable copy of otherwise protected or masked kernel-control paths, potentially causing host denial of service or enabling container escape via /proc/sysrq-trigger or /proc/sys/kernel/core_pattern.
A runc container escape vulnerability involving a malicious config, /dev/console mount handling, and related race conditions.
