Descriptions

Xen 4.4.x, when running on an ARM system and "handling an unknown system register access from 64-bit userspace," returns to an instruction of the trap handler for kernel space faults instead of an instruction that is associated with faults in 64-bit userspace, which allows local guest users to cause a denial of service (crash) and possibly gain privileges via a crafted process.

Xen 4.4.x, cuando funciona con un sistema ARM y 'maneja un acceso al registro de un sistema desconocido de un espacio de usuario de 64 bits,' vuelve a una instrucción del manejador trap para fallos en espacios del kernel en lugar de una instrucción que está asociada con fallos en el espacio de usuario de 64 bits, lo que permite a usuarios locales invitados causar una denegación de servicio (caída) y posiblemente ganar privilegios a través de un proceso manipulado.
