CVE-2026-35362

The safe_traversal module in uutils coreutils, which provides protection against Time-of-Check to Time-of-Use (TOCTOU) symlink races using file-descriptor-relative syscalls, is incorrectly limited to Linux targets. On other Unix-like systems such as macOS and FreeBSD, the utility fails to utilize these protections, leaving directory traversal operations vulnerable to symlink race conditions.

Summary		(es) El módulo safe_traversal en uutils coreutils, que proporciona protección contra las condiciones de carrera de enlaces simbólicos (symlink races) de tipo Time-of-Check to Time-of-Use (TOCTOU) utilizando llamadas al sistema (syscalls) relativas a descriptores de archivo, está incorrectamente limitado a objetivos Linux. En otros sistemas tipo Unix como macOS y FreeBSD, la utilidad no logra utilizar estas protecciones, dejando las operaciones de salto de directorio vulnerables a condiciones de carrera de enlaces simbólicos.
