CVE-2026-35349

A vulnerability in the rm utility of uutils coreutils allows a bypass of the --preserve-root protection. The implementation uses a path-string check rather than comparing device and inode numbers to identify the root directory. An attacker or accidental user can bypass this safeguard by using a symbolic link that resolves to the root directory (e.g., /tmp/rootlink -> /), potentially leading to the unintended recursive deletion of the entire root filesystem.

Summary		(es) Una vulnerabilidad en la utilidad rm de uutils coreutils permite eludir la protección --preserve-root. La implementación utiliza una comprobación de cadena de ruta en lugar de comparar números de dispositivo e inodo para identificar el directorio raíz. Un atacante o usuario accidental puede eludir esta salvaguarda mediante el uso de un enlace simbólico que se resuelve en el directorio raíz (p. ej., /tmp/rootlink -> /), lo que podría llevar a la eliminación recursiva no intencionada de todo el sistema de archivos raíz.
