NewCVE-2025-62596 (opens in a new tab)How to fix?
Upgrade libcontainer to version 0.5.7 or higher.
Overview
libcontainer is a library for container control.
Affected versions of this package are vulnerable to UNIX Symbolic Link (Symlink) Following via insufficiently strict validation in the apparmor handling when resolving pathnames. An attacker can perform arbitrary writes to unintended procfs locations and potentially escape container isolation or cause denial of service by exploiting a race condition with shared-mount path substitution during component-by-component path resolution.
Note:
This vulnerability has a similar logic to CVE-2025-52881 in runc
