Descriptions
The ioapic_read_indirect function in virt/kvm/ioapic.c in the Linux kernel through 3.8.4 does not properly handle a certain combination of invalid IOAPIC_REG_SELECT and IOAPIC_REG_WINDOW operations, which allows guest OS users to obtain sensitive information from host OS memory or cause a denial of service (host OS OOPS) via a crafted application.
La función ioapic_read_indirect virt/kvm/ioapic.c en el kernel de Linux hasta v3.8.4 no controla correctamente una determinada combinación de IOAPIC_REG_SELECT inválida y operaciones IOAPIC_REG_WINDOW, permitiendo a usuarios invitados del SO obtener información confidencial de la memoria principal o causar una denegación de servicio a través de una aplicación diseñada.
