Descriptions

The altivec_unavailable_exception function in arch/powerpc/kernel/traps.c in the Linux kernel before 2.6.19 on 64-bit systems mishandles the case where CONFIG_ALTIVEC is defined and the CPU actually supports Altivec, but the Altivec support was not detected by the kernel, which allows local users to cause a denial of service (panic) by triggering execution of an Altivec instruction.

La función altivec_unavailable_exception en arch/powerpc/kernel/traps.c en el kernel de Linux en versiones anteriores a la 2.6.19 en sistemas de 64 bits gestiona de manera incorrecta el caso en el que se define CONFIG_ALTIVEC y la CPU es compatible con Altivec, pero esa compatibilidad no la detecta el kernel, lo que hace que los usuarios locales provoquen una denegación de servicio (pánico) desencadenando la ejecución de una instrucción de Altivec.
