CVE-2019-15030

Estado: ModificadaMedia (4.4)—

En el kernel de Linux versiones hasta 5.2.14 en la plataforma powerpc, un usuario local puede leer registros vectoriales de los procesos de otros usuarios por medio de una excepción Facility Unavailable. Para explotar la venerabilidad, un usuario local inicia una transacción (por medio de la instrucción de memoria transaccional de hardware tbegin) y entonces accede a los registros vectoriales. En algún punto, los registros vectoriales se corromperán con los valores de un proceso de Linux local diferente debido a una falta de comprobación del archivo arch/powerpc/kernel/process.c.
