Descriptions
xen/arm: Boot modules are not scrubbed The bootloader will load boot modules (e.g. kernel, initramfs...) in a temporary area before they are copied by Xen to each domain memory. To ensure sensitive data is not leaked from the modules, Xen must "scrub" them before handing the page over to the allocator. Unfortunately, it was discovered that modules will not be scrubbed on Arm.
xen/arm: Los módulos de arranque no se limpian. El cargador de arranque cargará los módulos de arranque (por ejemplo, kernel, initramfs...) en un área temporal antes de que sean copiados por Xen a la memoria de cada dominio. Para asegurar que no se filtren datos confidenciales de los módulos, Xen debe "scrub" antes de entregar la página al asignador. Desgraciadamente, se ha detectado que los módulos no se limpian en Arm
