Descriptions
An issue was discovered in Xen through 4.11.x on AMD x86 platforms, possibly allowing guest OS users to gain host OS privileges because small IOMMU mappings are unsafely combined into larger ones.
Se ha descubierto un problema en Xen hasta las versiones 4.11.x en plataformas AMD x86, que podría permitir que usuarios invitados del sistema operativo obtengan privilegios del host del sistema operativo. Esto se debe a que los mapeos de IOMMU pequeños se combinan de forma insegura con mapeos más grandes.
