The Debian security team deemed this advisory irrelevant for Debian:14.
NVD Description
Note: Versions mentioned in the description apply only to the upstream guix package and not the guix package as distributed by Debian.
A race condition in the Nix, Lix, and Guix package managers enables changing the ownership of arbitrary files to the UID and GID of the build user (e.g., nixbld* or guixbuild*). 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.
