Descriptions

The osf_wait4 function in arch/alpha/kernel/osf_sys.c in the Linux kernel before 2.6.39.4 on the Alpha platform uses an incorrect pointer, which allows local users to gain privileges by writing a certain integer value to kernel memory.

La función osf_wait4 de arch/alpha/kernel/osf_sys.c del kernel de Linux en versiones anteriores a la 2.6.39.4 de la plataforma Alpha utiliza un puntero incorrecto, lo que permite a usuarios locales escalar privilegios escribiendo un valor entero determinado en la memoria del kernel.
