Hi,
There is a bug reported on link below
http://bugzilla.kernel.org/show_bug.cgi?id=3745.
When i simulate that bug on 2.16.17.6 kernel on intel i386 i got same results as reported in bug.
But still i am not able to figure out whether the bug reported is actually a security issue or it is actually a bug inside a kernel.
Can anyone help me in this aspect?

Thanking in advance,
Pranavkumar Sawargaonkar.
