Detailed vulnerability description

The vulnerability allows a local user to gain access to sensitive information.

The copy_from_user function in the uaccess code in Linux kernel 2.6 before 2.6.19-rc1, when running on s390, does not properly clear a kernel buffer, which allows local user space programs to read portions of kernel memory by 'appending to a file from a bad address,' which triggers a fault that prevents the unused memory from being cleared in the kernel buffer. This vulnerability is addressed in the following product update: Linux, Linux kernel, 2.6.19 rc1
