Description

A local overflow exists in the Linux kernel. The 'ipv6_getsockopt_sticky()' function in script 'ipv6_sockglue.c' fails to provide proper boundary checking resulting in a null pointer dereference overflow. With a specially crafted request, an unprivileged user can read arbitrary kernel memory resulting in a loss of confidentiality. The information gathered could be of use in further attacks on the system.
