The Debian security team deemed this advisory irrelevant for Debian:13.
NVD Description
Note: Versions mentioned in the description apply only to the upstream guix package and not the guix package as distributed by Debian.
The Nix, Lix, and Guix package managers allow a bypass of build isolation in which a user can elevate their privileges to the build user account (e.g., nixbld or guixbuild). This affects Nix through 2.24.15, 2.26.4, 2.28.4, and 2.29.1; Lix through 2.91.2, 2.92.2, and 2.93.1; and Guix before 1.4.0-38.0e79d5b.
