      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nilfs2: propagar errores de lectura de directorio desde nilfs_find_entry() Syzbot inform\u00f3 que se produce un bloqueo de tarea en vcs_open() durante una prueba de fuzzing para nilfs2. La causa ra\u00edz de este problema es que en nilfs_find_entry(), que busca entradas de directorio, ignora los errores cuando falla la carga de una p\u00e1gina/folio de directorio a trav\u00e9s de nilfs_get_folio(). Si las im\u00e1genes del sistema de archivos est\u00e1n da\u00f1adas, y el i_size del inodo del directorio es grande, y la p\u00e1gina/folio del directorio se lee correctamente pero falla la comprobaci\u00f3n de cordura, por ejemplo, cuando est\u00e1 llena de ceros, nilfs_check_folio() puede seguir arrojando mensajes de error en r\u00e1fagas. Solucione este problema propagando el error a los llamadores cuando falla la carga de una p\u00e1gina/folio en nilfs_find_entry(). La interfaz actual de nilfs_find_entry() y sus llamadores est\u00e1 desactualizada y no puede propagar c\u00f3digos de error como -EIO y -ENOMEM devueltos a trav\u00e9s de nilfs_find_entry(), as\u00ed que arr\u00e9glenlo juntos."
