Descriptions

The KVM implementation in the Linux kernel before 2.6.36 does not properly reload the FS and GS segment registers, which allows host OS users to cause a denial of service (host OS crash) via a KVM_RUN ioctl call in conjunction with a modified Local Descriptor Table (LDT).

La implementación de KVM en el kernel de Linux anterior a v2.6.36 no recarga adecuadamente los segmentos de registro FS y GS, lo cual permite a usuarios del sistema operativo anfitrión causar una denegación de servicio (cuelgue del sistema operativo anfitrión) a través de una llamada KVM_RUN ioctl junto con una versión modificada de la Tabla de Descriptores Locales (LDT).
