En el kernel de Linux se ha resuelto la siguiente vulnerabilidad:

s390/debug: Corregir la desreferenciación de puntero NULL en debug_info_copy()

Cuando debug_register_static() falla, borra areas, active_pages y active_entries, pero deja sin cambios los límites de las áreas. Al copiar un área de este tipo, ya sea abriendo su archivo de vista o mediante debug_dump(), debug_info_copy() desreferencia los punteros NULL.

Omitir el bucle de copia cuando el origen no tiene áreas.
