Descriptions

In FreeBSD before 11.1-STABLE(r332303), 11.1-RELEASE-p10, 10.4-STABLE(r332321), and 10.4-RELEASE-p9, due to insufficient initialization of memory copied to userland in the Linux subsystem and Atheros wireless driver, small amounts of kernel memory may be disclosed to userland processes. Unprivileged authenticated local users may be able to access small amounts of privileged kernel data.

En FreeBSD, en versiones anteriores a la 11.1-STABLE(r332303), 11.1-RELEASE-p10, 10.4-STABLE(r332321) y 10.4-RELEASE-p9, debido a la insuficiente inicialización de la memoria copiada en userland en el subsistema de Linux y el controlador inalámbrico de Atheros, pequeñas cantidades de la memoria del kernel pueden divulgarse a los procesos de userland. Los usuarios locales sin privilegios autenticados podrían ser capaces de acceder a pequeñas cantidades de datos privilegiados del kernel.
