Bug Description

The ipc subsystem in the Linux kernel before 2.6.37-rc1 does not initialize
certain structures, which allows local users to obtain potentially
sensitive information from kernel stack memory via vectors related to the
(1) compat_sys_semctl, (2) compat_sys_msgctl, and (3) compat_sys_shmctl
functions in ipc/compat.c; and the (4) compat_sys_mq_open and (5)
compat_sys_mq_getsetattr functions in ipc/compat_mq.c.
