CVE-2025-62161

CVE-2025-62161 is a critical container escape vulnerability affecting Youki container runtime versions 0.5.6 and below. The flaw stems from insufficient validation of /dev/null during bind mounting, allowing an attacker to escape the container environment. With a CVSS score of 10.0, this vulnerability is easily exploitable over the network with no user interaction, leading to complete compromise of confidentiality, integrity, and availability of the host system. While no public exploit code or active exploitation has been observed, and community discussion is minimal, the high FAUCET Risk Score of 88/100 indicates significant potential danger. Organizations using affected Youki versions should upgrade to 0.5.7 immediately to mitigate this critical risk.
