CVE-2025-62596

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, youki’s apparmor handling performs insufficiently strict write-target validation, and when combined with path substitution during pathname resolution, can allow writes to unintended procfs locations. While resolving a path component-by-component, a shared-mount race can substitute intermediate components and redirect the final target. This issue is fixed in version 0.5.7.

Risk Analysis

This critical vulnerability in Youki container runtime versions 0.5.6 and below allows for writes to unintended procfs locations due to insufficient write-target validation and path substitution. With a perfect CVSS score of 10.0, this flaw poses an extremely severe risk, enabling remote attackers to achieve high impact on 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 strict validation of write targets and robust path resolution to prevent path substitution attacks within container runtimes. For generic hardening, regularly update container runtimes and apply security best practices for container deployments.

Technical Analysis

CVE-2025-62596 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 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.
