Descriptions

AMD processors may speculatively re-order load instructions which can result in stale data being observed when multiple processors are operating on shared memory, resulting in potential data leakage.

Los procesadores AMD pueden reordenar especulativamente las instrucciones de carga, lo que puede resultar en que sean observados datos obsoletos cuando varios procesadores operan en la memoria compartida, resultando en un posible filtrado de datos
