Descriptions
The restore_fpu_checking function in arch/x86/include/asm/fpu-internal.h in the Linux kernel before 3.12.8 on the AMD K7 and K8 platforms does not clear pending exceptions before proceeding to an EMMS instruction, which allows local users to cause a denial of service (task kill) or possibly gain privileges via a crafted application.
La función restore_fpu_checking en arch/x86/include/asm/fpu-internal.h en el kernel Linux anteriores a 3.12.8 en las plataformas AMD K7 y K8 no limpia las excepciones pendientes antes de proceder a una instrucción EMMS, lo cual permite a usuarios locales causar una denegación de servicio (task kill) o posiblemente obtener privilegios a través de una aplicación manipulada.
