Descriptions
arch/s390/kernel/ptrace.c in the Linux kernel before 3.15.8 on the s390 platform does not properly restrict address-space control operations in PTRACE_POKEUSR_AREA requests, which allows local users to obtain read and write access to kernel memory locations, and consequently gain privileges, via a crafted application that makes a ptrace system call.
arch/s390/kernel/ptrace.c en el kernel de Linux anterior a 3.15.8 en el plataforma s390 no restringe debidamente las operaciones de control de la restricción del espacio para direcciones en las solicitudes PTRACE_POKEUSR_AREA, lo que permite a usuarios locales obtener el acceso a la lectura y la escritura en las localizaciones de la memoria del kernel, y como consecuencia ganar privilegios, a través de una aplicación que realiza una llamada al sistema ptrace.
It was found that Linux kernel's ptrace subsystem did not properly sanitize the address-space-control bits when the program-status word (PSW) was being set. On IBM S/390 systems, a local, unprivileged user could use this flaw to set address-space-control bits to the kernel space, and thus gain read and write access to kernel memory.
