DESCRIPTION:
A weakness has been reported in Linux Kernel, which can be exploited
by malicious, local users to disclose potentially sensitive system
information.

information structure as a result of the "uname()" system call. This
can be exploited to disclose some kernel stack-based memory via the
UNAME26 execution domain.

Reported by Brad Spengler via a patch.
