Permission Misconfigurations in Nix, Lix, and Guix Package Managers

CVE-2025-52992

What is CVE-2025-52992?

Nix, Lix, and Guix package managers exhibit improper permissions management during build failures, potentially allowing unauthorized processes to alter the contents of a storage environment outside of the intended build sandbox. This vulnerability compromises the security model, as it could lead to privilege escalation by enabling processes to access and modify sensitive data. Updates are necessary to ensure that permissions are correctly set, mitigating risks associated with such failures.
