CVE-2025-62161

CWE-61Published: November 6, 2025· Updated: Jun 17, 2026

10.0

CVSS v3.1

Official Description

Youki is a container runtime written in Rust. In versions 0.5.6 and below, the initial validation of the source /dev/null is insufficient, allowing container escape when youki utilizes bind mounting the container's /dev/null as a file mask. This issue is fixed in version 0.5.7.

NVD Source

Risk Analysis

This critical vulnerability in Youki container runtime versions 0.5.6 and below allows for container escape due to insufficient validation of /dev/null bind mounts. With a perfect CVSS score of 10.0, this flaw poses an extremely severe risk, enabling remote attackers to achieve high impact on confidentiality, integrity, and availability. The absence of an EPSS score and KEV listing means its exploitation likelihood is not yet publicly assessed or confirmed.

No public exploit is currently known for this vulnerability. Given the network attack vector and low attack complexity, it is remotely exploitable.

Recommended Action

Upgrade Youki to version 0.5.7 or newer. Ensure rigorous validation of bind mount sources, especially for special devices like /dev/null, to prevent container escapes. For generic hardening, regularly update container runtimes and apply security best practices for container deployments.

Technical Analysis

CVE-2025-62161 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 10.0.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
