Linux Kernel IBM S/390 strnlen_user Local Vulnerability

The Linux kernel on IBM S/390 platforms is prone to a local vulnerability. This issue is due to a flaw in the 'strnlen_user()' kernel function.

The direct impact of exploiting this issue is currently unknown, but local users may potentially exploit this issue to cause denial-of-service conditions or possibly gain access to potentially sensitive information.

This BID will be updated as more information is disclosed.

This issue affects Linux kernel versions prior to 2.6.16 running on the IBM S/390 platform.
