Descriptions
The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation.
La función xen_biovec_phys_mergeable en drivers/xen/biomerge.c en Xen podría permitir que usuarios invitados locales del sistema operativo corrompan transmisiones en bloque de datos del sistema y, consecuentemente, obtengan información sensible de la memoria, provoquen una denegación de servicio o consigan privilegios del SO mediante el aprovechamiento del cálculo incorrecto de block IO merge-ability.
