CVE-2022-27651 is a medium-severity vulnerability rated 6.8/10 on the CVSS scale. A flaw was found in buildah where containers were incorrectly started with non-empty default permissions. A bug was found in Moby (Docker Engine) where containers were incorrectly started with non-empty inheritable Linux process capabilities, enabling an attacker with access to programs with inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs. EPSS estimates a 1.23% chance of exploitation in the next 30 days.
