El kernel de Linux v2.6.33.2 y anteriores, cuando esta sobre un sistema de fichero ReiserFS, no restringe adecuadamente la lectura o escritura al directorio .reiserfs_priv, lo que permite a usuarios locales conseguir privilegios mediante la modificación de (1) atributos extendidos o (2) ACLs, como se demuestra mediante el borrado de un fichero bajo .reiserfs_priv/xattrs/.

Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
