CVE-2025-46415 Details
Description
A race condition in the Nix, Lix, and Guix package managers allows the removal of content from arbitrary folders. This affects Nix before 2.24.15, 2.26.4, 2.28.4, and 2.29.1; Lix before 2.91.2, 2.92.2, and 2.93.1; and Guix before 1.4.0-38.0e79d5b.
A race condition vulnerability has been identified in the Nix, Lix, and Guix package managers, allowing local users to delete files from arbitrary directories. This issue arises from a flawed recursive deletion function that fails to properly manage temporary file paths, creating a window for exploitation. The vulnerability affects Nix versions prior to 2.24.15, 2.26.4, 2.28.4, and 2.29.1; Lix versions prior to 2.91.2, 2.92.2, and 2.93.1; and Guix versions prior to 1.4.0-38.0e79d5b.
Users are advised to upgrade to Nix versions 2.24.15, 2.26.4, 2.28.4, or 2.29.1; Lix versions 2.91.2, 2.92.2, or 2.93.1; and Guix version 1.4.0-38.0e79d5b. Instructions for upgrading Guix on NixOS and other distributions are available on the Guix website.
